Abstract:
An end point closing wall forming device of an extrusion type underground diaphragm wall comprises a main body ( 1 ) and a vibration water spraying device. The vibration water spraying device is fixedly disposed inside the main body ( 1 ). The end point closing wall forming device of an extrusion type underground diaphragm wall further comprises a separation device. The separation device is movably sheathed on the outer side of a short edge ( 11 ′) of the main body ( 1 ). Also provided is a method for operating an end point closing wall forming device of an extrusion type underground diaphragm wall.

Claim (Index 5):
A method for closing end-of-wall for a press-fit underground continuous wall, comprises the following steps: Step 1: Assembly: According to the design of the depth and thickness of the diaphragm wall, select the appropriate type of basic section ( 10 ) and The auxiliary section ( 10 \u2032) is in turn docked on the ground. The vertical total length is limited by the design elevation and the construction process conditions by increasing or decreasing the auxiliary sections ( 10 \u2032) of different lengths. When the upper and lower sections are connected, ( 8 ) aligned to prevent water seepage, but also should be set vertically on the outer wall ( 3 ) of the threaded holes ( 35 \u2033) aligned, the outer wall body ( 3 ), The fastening cover ( 44 ) is provided with the plastic rivets ( 22 ) at the bottom ends of the separation rail ( 5 ) and the small external wall body ( 3 \u2032) by tightening the bolts ( 35 )  5 ) and the small external wall body ( 3 \u2032) to prevent the muddy water from entering the blockage. Process Step Two-way motion application: When the fixed body ( 1 ) does not produce displacement:) Small dovetail ( 21 \u2032) from the main body ( 1 ) into the small concave dovetail ( 17 ) Along the small concave dovetail groove ( 17 ) from top to bottom for a single movement of the unit, so that the pawl ( 18 ) and the shoulder abutment ( 6 ) touch, then the bottom of the pawl ( 18 ) The slope of the upper part of the convex shoulder ( 6 ) in the center of the small concave dovetail groove ( 17 ) on the short side ( 11 \u2032) of the cavity ( 2 ) continues to crawl, forcing the pawl ( 18 ) to convert the vertical movement energy through the bevel mechanics principle The pawl shaft  23  is urged to move the pawl back shoulder  23  to press the supporting spring  25  to move horizontally along the guide shaft  27  so that the pawl  18  is compressed and retracted into the pawl chamber  24 ), The small dovetail ( 21 \u2032) can reach the predetermined position at the bottom of the basic section ( 10 ) through the protruding shoulder ( 6 ); when the separating device is glued with concrete without displacement: the main body And the upper bevel of the convex shoulder ( 6 ) collides with the lower bevel of the pawl ( 18 ). According to the aforementioned bevel mechanics, the pawl ( 18 ) is compressed and retracted into the pawl chamber ( 24 ), So that the convex shoulder ( 6 ) passes smoothly through the pawl ( 18 ), the main body ( 1 ) can continue to ascend until it is pulled out of the ground; when the main body ( 1 ) and the separation device are simultaneously pushed into the ground, One-way body movement At this time, the flat lower surface of the convex shoulder ( 6 ) fixed at the center of the small concave dovetail groove ( 17 ) on the side of the short side ( 11 \u2032) is connected with the upper part of the pawl ( 18 ) ( 21 \u2032) of the separation orbit, the small dovetail ( 21 \u2032) of the separation orbit can not be used except for the vertical movement up and down, due to the restriction of the small concave dovetail groove ( 17 ) on the small dovetail ( 21 \u2032 Unless the top contact surface is damaged by shearing, otherwise, the flat surface at the lower part of the convex shoulder ( 6 ) drives the upper flat surface of the pawl ( 18 ) to drive the whole separation device Can only be synchronized down until it arrives at a predetermined underground place without mutual movement or separation; process step three, the end of the separation closed: first closed wall into the wall device ( 45 ) The first automatic wall forming device ( 46 ) concave dovetail groove ( 7 ) into the closed wall device ( 45 ) separation track Dovetail ( 21 ) and squeezed into the ground, timely filled with concrete, and then static pile driver along Next to the axis of the diaphragm wall, insert the concave groove ( 7 ) of the second automatic walling device ( 46 \u2032 ( 46 \u2032) into the underground swallowtail track ( 7 \u2032) and squeeze into the ground, fill the concrete in time and slowly raise the first automatic wall-forming device ( 46 ) and double-flap valve Under the action of gravity, the inner cavity ( 2 ) concrete immediately flows out of the soil space which is filled upwards by the filling body ( 1 ) to form the first segment of underground unit wall. Due to the unidirectional motion principle, the separation device does not have the function of following the automatic wall The upper condition of the device ( 46 ) is still attached to the wall-closing device ( 45 ), and the concrete flowing out of the automatic wall-forming device ( 46 ) is rapidly adhered to the outside of the separation track ( 5 ) and the fin ( 19 ) When the construction of underground continuous wall reaches the end of the enclosure, the last automatic wall forming device ( 46 \u2033) convex dovetail track ( 7 \u2032) into the closed wall device ( 45 ) rear concave The dovetail slot ( 7 ) is extruded into the same depth underground to complete the mechanical closure between the end closure devices; both the first ( 45 ) and the other ( 46 \u2033) Fill the concrete, start the electric vibrator ( 32 ) or the air source vibrator ( 32 \u2032) to gradually raise the closed wall Since the earliest concrete is already hardened and sticking to the separation track ( 5 ) near the concrete and the wing ( 19 ), its viscosity is much greater than that of the supporting spring ( 25 ) plus wing) Plastic Rivets ( 22 ) The sum of the pulling forces plus the side friction between the small female dovetail ( 17 ) and the small dovetail ( 21 \u2032), so as to meet the upward unidirectional motion of the body ( 1 ) The main body  1  of the closed wall forming device  45  is pulled out and the separation rails  5  and the wing  19  and the protective cover  44  are left in the newly formed concrete underground continuous wall; An automatic wall forming device ( 46 \u2033) is lifted while vibrating, and the last automatic wall forming device ( 46 \u2033) is pulled out because no concrete is solidified at the front and rear sleeves of the device, The separation rails ( 5 ), the wings ( 19 ) and the \u201c \u201d flaps ( 19 \u2032) are left in the concrete wall section to form a good impermeable structure.
