DETAILED DESCRIPTION

For a general understanding, reference is made to the drawings. In the drawings, like references have been used throughout to designate identical or equivalent elements. It is also noted that the drawings may not have been drawn to scale and that certain regions may have been purposely drawn disproportionately so that the features and concepts may be properly illustrated.

An example of a pile for providing gripping contact with grout and resisting grout from shearing is illustrated inFIG.2. More specifically,FIG.2is a schematic view of one embodiment of a deformed displacement pile.

As illustrated inFIG.2, a deformed displacement pile100is an elongated, tubular pipe with a hollow central chamber having threads300on the outer surface. A bottom section of the deformed displacement pile100includes a soil (medium) displacement head108. Soil (medium) displacement head108has a cutting blade112that has a leading edge114and a trailing edge116.

The leading edge114of cutting blade112cuts into the soil (medium) as the deformed displacement pile100is rotated and loosens the soil (medium) at such contact point. The soil (medium) displacement head108may be equipped with a point118to promote this cutting.

The loosened soil (medium) passes over cutting blade112and thereafter past trailing edge116. As the loosened soil medium passes over cutting blade112and thereafter past trailing edge116, the soil (medium) is laterally compacted by lateral compaction elements (discussed in more detail below). The lateral compaction elements create an annulus having outer wall500and void510.

The deformed displacement pile100also includes a deformation structure120that cuts into or gouges the outer wall500of the annulus or bore created by the displacement head108, so as to create a deformation in the outer wall500of the annulus or bore or a spiral groove in the outer wall500of the annulus or bore. The deformation in the outer wall500of the annulus or bore assists in preventing shearing between the grout and the soil (medium).

After the deformed displacement pile100is driven into position, grout (not shown) is introduced into the void510of the annulus. The grout can be introduced by means of gravity or pressure into the void510of the annulus.

Additionally, since the deformed displacement pile100is a hollow tube, the grout can be introduced into the void510of the annulus through the hollow tube by means of gravity or pressure, wherein the deformed displacement pile100would include openings (not shown) that allows the grout to leave the pile and enter into the void510of the annulus.

The introduced grout surrounds the threads300of the deformed displacement pile100to provide gripping interface between the grout and the deformed displacement pile100, as well as, providing an interface that resists the grout from shearing along the surface between the grout and the deformed displacement pile100.

Another example of a pile for providing gripping contact with grout and resisting grout from shearing is illustrated inFIG.3. More specifically,FIG.3is a schematic view of one embodiment of a deformed displacement pile.

As illustrated inFIG.3, a deformed displacement pile100is an elongated, tubular pipe400with a hollow central chamber having projections410on the outer surface. The projections410may be randomly placed on the outer surface of the deformed displacement pile100or be placed in a pattern. The projections410extend out from the outer surface of the deformed displacement pile100into the void510of an annulus without coming into contact with an outer wall500of the annulus.

A bottom section of the deformed displacement pile100includes a soil (medium) displacement head108. Soil (medium) displacement head108has a cutting blade112that has a leading edge114and a trailing edge116.

The leading edge114of cutting blade112cuts into the soil (medium) as the deformed displacement pile100is rotated and loosens the soil (medium) at such contact point. The soil (medium) displacement head108may be equipped with a point118to promote this cutting.

The loosened soil (medium) passes over cutting blade112and thereafter past trailing edge116. As the loosened soil medium passes over cutting blade112and thereafter past trailing edge116, the soil (medium) is laterally compacted by lateral compaction elements (discussed in more detail below). The lateral compaction elements create an annulus having outer wall500and void510.

The deformed displacement pile100also includes a deformation structure120that cuts into or gouges the outer wall500of the annulus or bore created by the displacement head108, so as to create a deformation in the outer wall500of the annulus or bore or a spiral groove in the outer wall500of the annulus or bore. The deformation in the outer wall500of the annulus or bore assists in preventing shearing between the grout and the soil (medium).

After the deformed displacement pile100is driven into position, grout (not shown) is introduced into the void510of the annulus. The grout can be introduced by means of gravity or pressure into the void510of the annulus.

Additionally, since the deformed displacement pile100is a hollow tube, the grout can be introduced into the void510of the annulus through the hollow tube by means of gravity or pressure, wherein the deformed displacement pile100would include openings (not shown) that allows the grout to leave the pile and enter into the void510of the annulus.

The introduced grout surrounds the projections410of the deformed displacement pile100to provide gripping interface between the grout and the deformed displacement pile100, as well as, providing an interface that resists the grout from shearing along the surface between the grout and the deformed displacement pile100.

A third example of a pile for providing gripping contact with grout and resisting grout from shearing is illustrated inFIG.4. More specifically,FIG.4is a schematic view of one embodiment of a deformed displacement pile.

As illustrated inFIG.4, a deformed displacement pile100is an elongated, tubular pipe400with a hollow central chamber having indentations420on the outer surface. The indentations420may be randomly placed on the outer surface of the deformed displacement pile100or be placed in a pattern. The indentations420extend inwardly from the outer surface of the deformed displacement pile100away from the void510of an annulus.

A bottom section of the deformed displacement pile100includes a soil (medium) displacement head108. Soil (medium) displacement head108has a cutting blade112that has a leading edge114and a trailing edge116.

The leading edge114of cutting blade112cuts into the soil (medium) as the deformed displacement pile100is rotated and loosens the soil (medium) at such contact point. The soil (medium) displacement head108may be equipped with a point118to promote this cutting.

The loosened soil (medium) passes over cutting blade112and thereafter past trailing edge116. As the loosened soil medium passes over cutting blade112and thereafter past trailing edge116, the soil (medium) is laterally compacted by lateral compaction elements (discussed in more detail below). The lateral compaction elements create an annulus having outer wall500and void510.

The deformed displacement pile100also includes a deformation structure120that cuts into or gouges the outer wall500of the annulus or bore created by the displacement head108, so as to create a deformation in the outer wall500of the annulus or bore or a spiral groove in the outer wall500of the annulus or bore. The deformation in the outer wall500of the annulus or bore assists in preventing shearing between the grout and the soil (medium).

After the deformed displacement pile100is driven into position, grout (not shown) is introduced into the void510of the annulus. The grout can be introduced by means of gravity or pressure into the void510of the annulus.

Additionally, since the deformed displacement pile100is a hollow tube, the grout can be introduced into the void510of the annulus through the hollow tube by means of gravity or pressure, wherein the deformed displacement pile100would include openings (not shown) that allows the grout to leave the pile and enter into the void510of the annulus.

The introduced grout surrounds the indentations420of the deformed displacement pile100to provide gripping interface between the grout and the deformed displacement pile100, as well as, providing an interface that resists the grout from shearing along the surface between the grout and the deformed displacement pile100.

A fourth example of a pile for providing gripping contact with grout and resisting grout from shearing is illustrated inFIG.5. More specifically,FIG.5is a schematic view of one embodiment of a deformed displacement pile.

As illustrated inFIG.5, a deformed displacement pile100is an elongated, tubular pipe400with a hollow central chamber having indentations420and projections410on the outer surface. The indentations420and projections410may be randomly placed on the outer surface of the deformed displacement pile100or be placed in a pattern. The indentations420extend inwardly from the outer surface of the deformed displacement pile100away from the void510of an annulus, and the projections410extend out from the outer surface of the deformed displacement pile100into the void510of an annulus without coming into contact with an outer wall500of the annulus.

A bottom section of the deformed displacement pile100includes a soil (medium) displacement head108. Soil (medium) displacement head108has a cutting blade112that has a leading edge114and a trailing edge116.

The leading edge114of cutting blade112cuts into the soil (medium) as the deformed displacement pile100is rotated and loosens the soil (medium) at such contact point. The soil (medium) displacement head108may be equipped with a point118to promote this cutting.

The loosened soil (medium) passes over cutting blade112and thereafter past trailing edge116. As the loosened soil medium passes over cutting blade112and thereafter past trailing edge116, the soil (medium) is laterally compacted by lateral compaction elements (discussed in more detail below). The lateral compaction elements create an annulus having outer wall500and void510.

The deformed displacement pile100also includes a deformation structure120that cuts into or gouges the outer wall500of the annulus or bore created by the displacement head108, so as to create a deformation in the outer wall500of the annulus or bore or a spiral groove in the outer wall500of the annulus or bore. The deformation in the outer wall500of the annulus or bore assists in preventing shearing between the grout and the soil (medium).

After the deformed displacement pile100is driven into position, grout (not shown) is introduced into the void510of the annulus. The grout can be introduced by means of gravity or pressure into the void510of the annulus.

Additionally, since the deformed displacement pile100is a hollow tube, the grout can be introduced into the void510of the annulus through the hollow tube by means of gravity or pressure, wherein the deformed displacement pile100would include openings (not shown) that allows the grout to leave the pile and enter into the void510of the annulus.

The introduced grout surrounds the indentations420and projections410of the deformed displacement pile100to provide gripping interface between the grout and the deformed displacement pile100, as well as, providing an interface that resists the grout from shearing along the surface between the grout and the deformed displacement pile100.

In the embodiment shown inFIGS.6and7, there are three such lateral compaction elements. The lateral compaction element220near the end of the deformed displacement pile has a diameter less than the diameter from the lateral compaction element200near deformation structure120.

In this fashion, the soil is laterally compacted by the first lateral compaction element220, more compacted by the second lateral compaction element210(enlarging the diameter of the bored hole) and even more compacted by the third lateral compaction element200.

The cutting blade112primarily cuts into the soil and only performs minimal soil compaction. The deformation structure120is disposed above the lateral compaction elements200. After the widest compaction element200has established an annulus with a regular diameter, deformation structure120cuts into the edge of the outer wall500of the annulus to leave a spiral pattern in the annulus's perimeter or circumference.

It is noted that, as illustrated inFIG.7, the deformation structure120has a height that changes over the length of the deformation structure120from its greatest height at end206to a lesser height at end208as the deformation structure120coils about the deformed displacement pile in a helical configuration.

Large pipe shaped piles to be driven into the ground are difficult to handle and move to the vertical position to install. Conventionally, to couple handle large pipe shaped piles with the driver, the heavy drive equipment is turned near horizontal and a coupler type section is slid over the end. This conventional coupling process is difficult and requires alignment radially with the drive machine. The conventional coupling process often jambs and pinches during this operation.

FIG.17illustrates another example of a bottom section of the deformed displacement pile ofFIG.5. As illustrated inFIG.17, the deformed displacement pile includes threads300on the outer surface of the deformed displacement pile.

The bottom section of the deformed displacement pile also includes a soil (medium) loosen bit or head600to loosen the soil (medium) around the deformed displacement pile as the deformed displacement pile is driven therein. The soil (medium) loosen bit or head600includes a lateral compaction structure700to laterally compact the loosen soil (medium) to create an annulus with an outer wall500and a void510.

FIG.18illustrates an example of bottom section of a displacement pile wherein the lateral compaction element extends up the pile shaft beyond the cutting blade. As illustrated inFIG.18, the soil (medium) displacement head108is connected to an elongated, tubular pipe102with a hollow central chamber. A top section of the elongated, tubular pipe102may include a reverse auger (not shown) and/or the top section of the elongated, tubular pipe102may include indentations (not shown) and/or projections (not shown) to provide a gripping interface between grout introduced into an annulus produced by the displacement pile and the displacement pile, as well as, providing an interface that resists the grout from shearing along the surface between the grout and the displacement pile.

The soil (medium) displacement head108also includes a cutting blade112that has a leading edge114and a trailing edge116.

The leading edge114of cutting blade112cuts into the soil (medium) as the displacement pile is rotated and loosens the soil (medium) at such contact point. The soil (medium) displacement head108may be equipped with a point118to promote this cutting.

The loosened soil (medium) passes over cutting blade112and thereafter past trailing edge116.

The soil (medium) displacement head108includes at least one lateral compaction element. In the embodiment shown inFIG.18, there are at least three lateral compaction elements. The lateral compaction element220has a diameter less than the diameter of the lateral compaction element200. The lateral compaction element210has a diameter that is between the diameters of the lateral compaction element220and the lateral compaction element200. In this fashion, the soil is laterally compacted by the first lateral compaction element220, more compacted by the second lateral compaction element210(enlarging the diameter of the bored hole) and even more compacted by the third lateral compaction element200. The lateral compaction elements (220,210, and200), as the displacement head108is rotated into the soil (medium), laterally compacts the soil (medium) to create an annulus or bore.

As illustrated inFIG.18, the lateral compaction element200includes, thereon, a deformation structure120that cuts into or gouges the wall of the annulus or bore created by lateral compaction elements (220,210, and200), so as to create a deformation in the wall of the annulus or bore. The deformation in the wall of the annulus or bore assists in preventing shearing between the grout and the soil (medium).

In this embodiment, as further illustrated inFIG.18, the annulus or bore created by the lateral compaction is maintained beyond the trailing edge116of the cutting blade112. As illustrated inFIG.18, a first lateral retention element201and a second lateral retention element202extend beyond the trailing edge116of the cutting blade112. The first lateral retention element201and the second lateral retention element202have the same diameter as the lateral compaction element200. The lateral retention elements assist in preventing a portion of the annulus, above the trailing edge116of the cutting blade112, from collapsing before the grout can be introduced into the annulus, thereby enabling an effectively filling of the annulus with grout.

It is noted that is preferred the lateral retention element or elements extend at least one rotation around the tube102beyond the trailing edge116of the cutting blade112. However, any number or fraction thereof of rotations beyond the trailing edge116of the cutting blade112can be realized in preventing the annulus from collapsing before the grout can be introduced into the annulus, thereby enabling an effectively filling of the annulus with grout.

As illustrated inFIG.18, the deformation structure120may be co-located with the lateral compaction element200, or alternatively, the deformation structure120may be co-located with the first lateral retention element201or the second lateral retention element202. Alternatively, the deformation structure120may be continuously co-located with the lateral compaction element200, the first lateral retention element201, and the second lateral retention element202.

Although illustrated as separate lateral compaction elements, the first lateral compaction element extension201and/or the second lateral compaction element extension202may be a continuous lateral compaction element of lateral compaction element200.

Although described in all the embodiments above as separate lateral compaction element, the lateral compaction element may be a continuous lateral compaction element.

FIG.33illustrates an example of bottom section of a displacement pile wherein a lateral compaction maintenance element extends up the pile shaft beyond the cutting blade. As illustrated inFIG.33, the soil (medium) displacement head108is connected to an elongated, tubular pipe102with a hollow central chamber. A top section of the elongated, tubular pipe102may include a reverse auger (not shown) and/or the top section of the elongated, tubular pipe102may include indentations (not shown) and/or projections (not shown) to provide a gripping interface between grout introduced into an annulus produced by the displacement pile and the displacement pile, as well as, providing an interface that resists the grout from shearing along the surface between the grout and the displacement pile.

The soil (medium) displacement head108also includes a cutting blade112that has a leading edge114and a trailing edge116.

The leading edge114of cutting blade112cuts into the soil (medium) as the displacement pile is rotated and loosens the soil (medium) at such contact point. The soil (medium) displacement head108may be equipped with a point118to promote this cutting. The loosened soil (medium) passes over cutting blade112and thereafter past trailing edge116.

The soil (medium) displacement head108includes at least one lateral compaction element. In the embodiment shown inFIG.33, there are at least four lateral compaction elements (220,210,200,201). The lateral compaction element220has a diameter less than the diameter of the lateral compaction element200. The lateral compaction element210has a diameter that is between the diameters of the lateral compaction element220and the lateral compaction element200. The lateral compaction element201may have a diameter greater than a diameter of the lateral compaction element200, or the lateral compaction element201may have a diameter equal to the diameter of the lateral compaction element200. In this fashion, the soil is laterally compacted by the first lateral compaction element220, more compacted by the second lateral compaction element210(enlarging the diameter of the bored hole) and even more compacted by the third lateral compaction element200, and if the lateral compaction element201has a diameter greater than a diameter of the lateral compaction element200, even more compacted by the fourth lateral compaction element201.

The lateral compaction element201includes a deformation structure120that cuts into or gouges the wall of the annulus or bore created by lateral compaction elements (220,210,200,201), so as to create a deformation in the wall of the annulus or bore. The deformation in the wall of the annulus or bore assists in preventing shearing between the grout and the soil (medium).

In this embodiment, as illustrated inFIG.33, a lateral compaction maintenance element2102is positioned above the trailing edge116of the cutting blade112and the fourth lateral compaction element201. As illustrated inFIG.33, the lateral compaction maintenance element2102has the same diameter as the lateral compaction element201. The lateral compaction maintenance element2102assists in preventing the annulus from collapsing before the grout can be introduced into the annulus, thereby enabling an effectively filling of the annulus with grout.

The lateral compaction maintenance element2102may be, as illustrated inFIG.33, a hollow cylinder that is connected to the elongated, tubular pipe102via spacers2103. The spacers2103may be constructed of a metal or metal alloy and welded to the elongated, tubular pipe102and the lateral compaction maintenance element2102.

It is noted that the length or extension of the lateral compaction maintenance element2102may vary depending upon the nature of the medium (soil). If the medium (soil) is very loose, the length or extension of the lateral compaction maintenance element2102will be greater than the length or extension of the lateral compaction maintenance element2102when the medium (soil) is hard.

As illustrated inFIG.33, the deformation structure120may be co-located with the lateral compaction element201, or alternatively, the deformation structure120may be co-located with the lateral compaction maintenance element2102. Alternatively, the deformation structure120may be continuously co-located with the lateral compaction element201and the lateral compaction maintenance element2102.

Although described and illustrated as separate lateral compaction elements, the lateral compaction elements may be a continuous lateral compaction element.

It is noted that the lateral compaction maintenance element2102is located on the elongated, tubular pipe102above the cutting blade112.

It is further noted that a bottom of the lateral compaction maintenance element2102is located in close proximity to the trailing edge116of the cutting blade112to prevent a collapse of the annulus formed by the lateral compaction element(s).

The swing provided by the first swivel connector3450and the second swivel connector3455is orthogonal to the swing provided by the third swivel connector3450and the fourth swivel connector3455.

In other words, as illustrated inFIG.34, the two-direction swing pile adapter3400provides a minimum swing of 40° in a first direction and a minimum swing of 20° in a second direction, wherein the first direction is orthogonal to the second direction.

More specifically, as illustrated inFIG.34, the two-direction swing pile adapter3400provides a minimum swing of 40° in a direction orthogonal to the cross support bar3412and provides a minimum swing of 20° in a direction parallel to the cross support bar3412.

The degrees of freedom, provided by the two-direction swing pile adapter3400, enable a coupling to a non-plumb pile and erecting plumb supporting excavation members.

The two-direction swing pile adapter3400provides two degrees of adaptability when attempting to couple a pile to pile driver. The adaptability enhances the coupling process when the pile driver cannot be positioned directly over the pile, thereby enabling driving the pile from different angles.

FIG.35illustrates a pound-driven pile3500. A pound-driven pile is a pile that is driven into the medium (ground) solely by a pile driver that pounds (hammers) the pile. The pile driver applies no rotation to the pile as it is driven.

As illustrated inFIG.35, the pound-driven pile3500includes a shaft3510and a displacement head3530that includes a head3525for transferring the force from the pounding to the medium to break up the medium and a lateral compaction member3523for laterally compacting the medium to create an annulus3520in the medium.

The shaft3510may be hollow to allow the introduction of grout into the annulus3520. Moreover, the displacement head3530may include an opening to allow the introduction of grout into the annulus3520.

FIG.36illustrates a pound-driven pile3600that includes fins (3640and3650). A pound-driven pile is a pile that is driven into the medium (ground) solely by a pile driver that pounds (hammers) the pile. The pile driver applies no rotation to the pile as it is driven.

As illustrated inFIG.36, the pound-driven pile3600includes a shaft3610and a displacement head3630that includes a head3625for transferring the force from the pounding to the medium to break up the medium and a lateral compaction member3623for laterally compacting the medium to create an annulus3620in the medium.

The shaft3610has fins (3640and3650) orientated at different angles. The fins (3640and3650) orientated such that when the pound-driven pile3600is pounded by the pile driver, the fins (3640and3650) cause the pound-driven pile3600to rotate.

The fins (3640and3650) are solid projections that extend outwardly from the shaft3610. The fins (3640and3650) extend outwardly enough from the shaft3610to engage the annulus3610and cut continuous grooves3625into the wall of the annulus3610. The continuous grooves3625prevent shearing at the interface between the grout and the wall of the annulus3610.

The shaft3610may be hollow to allow the introduction of grout into the annulus3620. Moreover, the displacement head3630may include an opening to allow the introduction of grout into the annulus3620.

The shaft3610may include threads, projections, and/or indentations, as illustrated inFIG.2,3,4, or5. The threads, projections, and/or indentations of shaft3610provide a gripping interface between the grout introduced into the annulus3620and the shaft3610, as well as, providing an interface that resists the grout from shearing along the surface between the grout and the shaft3610.

FIG.37illustrates a micropile4000that includes a casing4100. A pile shaft4200is located within the casing4100. A displacement head4400is connected to the pile shaft4200. The displacement head4400creates an annulus500in a medium (such as soil) as the displacement head4400is driven (rotated in direction4500) into the medium.

As illustrated inFIG.37, the displacement head4400may include a helical blade4450having a leading edge and a trailing edge. The driving helical blade4450is configured to move the displacement head4400into the medium. The displacement head4400also may include a lateral compaction member4425to create the annulus500within the medium. The lateral compaction member4425has a diameter equal to or larger than a diameter of the casing4100. The displacement head4400may include a displacement head point member4475.

The micropile4000, as illustrated inFIG.37, includes a helical blade4300on the casing4100. The helical blade4300is configured to drive the casing4100out of a medium when the casing4100is rotated in the direction4550, as illustrated inFIG.38.

More specifically, as illustrated inFIG.38, as the casing4100, with helical blade4300, is rotated in the direction4550, the casing4100travels out of the medium, and the helical blade4300creates deformations550in the wall of the annulus500. The deformations550assist in preventing shear between a grout (not shown), which is used to fill the annulus500, and the wall of the annulus500.

FIG.39illustrates a micropile4000that includes a casing4100. A pile shaft4200is located within the casing4100. A displacement head4400is connected to the pile shaft4200. The displacement head4400creates an annulus500in a medium as the displacement head4400is driven (rotated in direction4500) into the medium.

As illustrated inFIG.39, the displacement head4400may include a helical blade4450having a leading edge and a trailing edge. The driving helical blade4450is configured to move the displacement head4400into the medium. The displacement head4400also may include a lateral compaction member4425to create the annulus500within the medium. The lateral compaction member4425has a diameter equal to or larger than a diameter of the casing4100. The displacement head4400may include a displacement head point member4475.

The micropile4000, as illustrated inFIG.39, does not include a helical blade on the casing.

As illustrated inFIG.40, the casing4100is disengaged from the displacement head4500when the casing4100is rotated in the direction4550. This allows the displacement head4500to remain in place in the medium as the casing4100is moved away from the displacement head4500or out of the annulus500. The casing4100maintains the integrity of the annulus500as the micropile4000is driven into the medium, and the casing4100can be removed after the micropile4000has been driven to a desired depth in the medium. The casing4100can be removed as grout or other filling material is pumped into the annulus500.

As illustrated inFIGS.41and42, the casing4100and displacement head4400have an interface5000. More specifically, casing4100has an interface that includes surface4150and surface4155, and displacement head4400has an interface that includes surface4450and surface4455.

It is note that surface4150is non-orthogonal to surface4155, and surface4450is non-orthogonal to surface4455.

As illustrated inFIG.41, as the casing is rotated in direction4500, the surface4150of casing4100engages the surface4450of displacement head4400, as shown by the arrows. More specifically, as the casing is rotated in direction4500, the surface4150of casing4100engages the surface4450of displacement head4400so that torque, if desired, can be transferred from the casing4100to the displacement head4500. The surfaces4150and4450are orientated to enable effective transference of torque; preferably, the surfaces4150and4450are substantially orthogonal to the direction of torque being applied thereto.

As illustrated inFIG.42, as the casing4100is rotated in direction4550, the surface4150of casing4100disengages the surface4450of displacement head4400, as shown by the arrows. The surfaces4155and4455are orientated so as to enable effective disengagement when the casing is rotated in direction4550; preferably, the surfaces4155and4455are substantially parallel or non-orthogonal to the direction of torque being applied thereto when the casing is rotated in direction4500.

This allows the displacement head4500to remain in place in the medium as the casing4100is moved away from the displacement head4500or out of the annulus500. The casing4100maintains the integrity of the annulus500as the micropile4000is driven into the medium, and the casing4100can be removed after the micropile4000has been driven to a desired depth in the medium. The casing4100can be removed as grout or other filling material is pumped into the annulus500.

The interface5000ofFIGS.41and42allows the casing4100to be removed from the annulus or moved away from the displacement head4500, while leaving the displacement head4500in place.

As illustrated inFIGS.41and42, the interface of the casing4100is configured to engage the interface of the displacement head4500when the casing is rotated in a first direction (4500), and the interface of the casing4100is configured to disengage from the interface of the displacement head4500when the casing is rotated in a second (opposite) direction (4550).

This allows the displacement head4500to remain in place in the medium as the casing4100is moved away from the displacement head4500or out of the annulus500. The casing4100maintains the integrity of the annulus500as the micropile4000is driven into the medium, and the casing4100can be removed after the micropile4000has been driven to a desired depth in the medium. The casing4100can be removed as grout or other filling material is pumped into the annulus500.

It is noted that the displacement head4500may include a deformation structure to form a deformation in a wall of the annulus created by the displacement head4500.

It is noted that the torque needed to drive the displacement head4500into the medium can be supplied by rotating the casing4100or the pile shaft4200or a combination of both.

FIG.43illustrates a pile with different sized lateral compaction elements above the displacement head of the pile. As illustrated inFIG.43, a pile includes a shaft5102and soil (medium) displacement head5008having a cutting blade5112that has a leading edge5114and a trailing edge5116.

The leading edge5114of cutting blade5112cuts into the soil (medium) as the displacement pile is rotated and loosens the soil (medium) at such contact point. The soil (medium) displacement head5008may be equipped with a point5118to promote this cutting.

The loosened soil (medium) passes over cutting blade5112and thereafter past trailing edge5116.

The soil (medium) displacement head5008includes at least one lateral compaction element. In the embodiment shown inFIG.43, there are at least five lateral compaction elements. The lateral compaction element5220has a diameter less than the diameter of the lateral compaction element5200. The lateral compaction element5210has a diameter that is between the diameters of the lateral compaction element5220and the lateral compaction element5200. In this fashion, the soil is laterally compacted by the first lateral compaction element5220, more compacted by the second lateral compaction element5210(enlarging the diameter of the bored hole) and even more compacted by the third lateral compaction element5200. The lateral compaction elements (5220,5210, and5200), as the soil (medium) displacement head5008is rotated into the soil (medium), laterally compacts the soil (medium) to create an annulus or bore, having the walls thereof a first distance5010from the shaft5102.

As illustrated inFIG.43, the lateral compaction element5200includes, thereon, a deformation structure5120that cuts into or gouges the wall of the annulus or bore created by lateral compaction elements (5220,5210, and5200), so as to create a deformation in the wall of the annulus or bore. The deformation in the wall of the annulus or bore assists in preventing shearing between the grout and the soil (medium).

As further illustrated inFIG.43, the annulus or bore is further widened by lateral compaction elements (5310and5320) located on the shaft5102, above the soil (medium) displacement head5008. The lateral compaction element5310widens the annulus or bore such that the walls thereof, formed by the lateral compaction element5310, have a second distance5020from the shaft5102. Moreover, the lateral compaction element5320further widens the annulus or bore such that the walls thereof, formed by the lateral compaction element5330, have a third distance5030from the shaft5102.

It is noted that these lateral compaction elements (5310and5320) may include, thereon, a deformation structure5120that cuts into or gouges the wall of the annulus or bore created by lateral compaction elements (5310and5320).

The pile illustrated inFIG.43creates a stepped or variable annulus or bore, wherein the diameter of the annulus or bore incrementally increases in a direction away from the soil (medium) displacement head5008. The actual incremental increases depend on the number of lateral compaction elements located on the shaft5102, above the soil (medium) displacement head5008, wherein each lateral compaction element is a distinct size so as to annulus or bore walls that having varying distances from the from the shaft5102.

FIG.44illustrates a stepped lateral compaction element. As illustrated inFIG.4, a stepped lateral compaction element6000has a plurality of sections that have different diameters. It is noted that the stepped lateral compaction element6000may be located on a shaft of a pile above the displacement head.

In a first section, defined by walls6010, the stepped lateral compaction element6000has a first diameter6015(a distance between walls6010) that creates an annulus or bore with a diameter approximately equal to the first diameter6015.
