SHOVEL ATTACHMENT SAVES TIME AND EFFORT

On the Deschutes Project in Oregon, constructed by the Bureau
of Reclamation and now operated by the North Unit Irrigation District, a
Model U-9, Quickway Shovel is used most of the time as a dragline. The
equipment as designed requires the operator to use three levers in ex-
cavation work; one to swing the machine, one to drag the bucket, and one
to hoist the bucket. A skilled operator will drag and hoist the bucket and
swing the machine all at the same time, requiring operation of the three
levers against pressure with two hands. To do this means that the op-
erator has to let go of the swing lever with his left hand to operate one
of the bucket levers or use his right forearmto operate two bucket levers.
Such an operation results in delayed motion or, where the latter type of
operation is used, in extreme fatigue and a temporary paralysis of the
forearm at the end of an eight-hour shift.

An attachment designed and constructed by Mr. Huron Wise in
the Project's, Madras shop, provides for easier operation and increases
the output of the machine. Use of the device, by actual count and meas-
urement, permits handling 1/3 more material in a day.

The Attachment

As constructed in the factory, the drag and hoist levers of the
Model U9, Quickway Shovel are connected directly to hydraulic cylinders,
which in turn are connected with hydraulic lines to the main winch. They
are live levers. That is, they cannot be set in position. The operator
must pull these levers and hold them against hydraulic pressure in order
to operate the particular mechanism.

The attachment shown on the following page permits the oper-
ator to pull either one or both of the bucket levers against pressure in
the hydraulic cylinder and lock them into position until released. The
device consists of an arrangement of adjustable links connecting the le-
vers to the hydraulic cylinders. Locking is accomplished without the use
of "dogs" or ratchets, by adjusting the vertical linkage so that the center
pin of the horizontal links is slightly below the axis of the horizontal link-
age.

The device can be constructed in any reasonably well equipped
shop. The installation made on the Deschutes Project has been in opera~
tion for some time without further adjustment. It has proven to be very
satisfactory.

If further details are desired, write the Manager, North Unit
Irrigation District, Madras, Oregon, or the Regional Director, Bureau
of Reclamation, Boise, Idaho.

COLUMBIA BASIN TRASHRACK

The trashrack shown in the photograph below is of the type
presently being installed on laterals in the West Canal area of the
Columbia Basin Project, Washington, The flat slope of the rack aids
in the removal of weeds and the landing mat deck provides good foot-
ing. The trashrack shown was installed in a lateral having a capac-
ity of 400 cfs,

Construction:
—

Surplus rails are used for the supporting cross members
and pipe for the rack varies from 3/4- to 1-1/4-inch heavy duty, de-
pending on the length of span, The rack shown was constructed of
1-1/4-inch pipe with the longest pipe length being about 20 feet,

The pipe is spaced 8-inch center to center and placed ona
slope no steeper than 4:1, Upper ends of the pipes are loosely at-
tached to the rail by large spikes which pass through holes in the ends
of the pipes and through the web of the rail, The foundation for the
rail cross member can be of concrete or serviceable timber, The


In the photograph below, an air compressor, concrete mixer, and agi-
tator, together with the water and cement, are conveniently available
to the work.

The 4-1/2-inch thick unreinforced concrete linings placed in
the West and East Low Canals have developed cracks in the side slopes
in certain areas, The trouble is occurring where the lining was placed
over fractured and jointed rock or permeable gravel in cut sections. The
distress is characterized by a settlement and cracking of the lining,
which upon removal discloses voids as much as 2 feet in depth, normal to
the canal slope, beneath the lining. The voids are apparently caused by
the seepage of water through joints in the lining, causing settlement of
the backfill material, or carrying the silt backfill material into voids in
the underlying rock or gravel subgrade.

Repairs for the lining, where the slabs of concrete are still in-
tact, are accomplished by drilling 2-1/2- to 3-inch holes through, the
lining in cracked and "hollow sounding" areas, and filling the voids with
a lean cement-sand grout. The grout consists of 1 part cement to 3 parts
of sand, using about 8 gallons of water per sack of cement and Durite,a


the operator finger tip control when spraying 100 to 200 feet from
the machine,

The unit is built on a metal base which can be placed in
any one-half-ton pickup with room to spare, It has a tank capacity

of 50 gallons, A diagram of the complete unit is shown on the fol-
lowing page and a wiring diagram and details of the hollow bronze

shaft are given below,

DESCHUTES WEIR POOL WEED SPRAYER

Use of the "Deschutes Weir Pool Weed Sprayer", planned and
constructed by Mr, Huron D, Wise, heavy duty mechanic, Deschutes
Project, Oregon, and used on the project, results in considerable sav-
ings in time, more weir pools and isolated areas being sprayed, and
the spraying operation being much better than that usually performed
with less efficient 3-gallon back-pack-type sprayers. The new device
delivers the spray material from the spray wand held in the operator's
hand in response to his pressing a button on the handle of the wand,
The device is shown in the photograph below.

Construction:

The unique feature of this unit is the elimination of a gas
engine for power, The pump and reel are both operated by two 6-volt
starter motors with remote controls on the boom handle which gives



Removing dogs and small animals both dead and alive from
concrete lined canals is a common chore on the Central Valley Proj-
ect in California, It can be a dangerous chore, Recently a ditch-
rider was bitten seriously about the face by a dog he had rescued and
the bites made hospitalization, including rabies treatment, necessary,
The ditchrider lost 14 days working time,

Gordon Johnson of the project came up with the idea of a dip~
net. As shown above, the dipnet is Similar to the type used by com-
mercial fishermen, with a long telescoping handle carried as standard
equipment by ditchriders in their vehicles, For further detail write

The new edition of the Concrete Manual will be of interest to all
engaged in project operation and maintenance. Like previous editions, a
full chapter has been devoted to the repair and maintenance of concrete,
and concrete structures. Some of the items covered in the new edition
of the Manual are: methods of repair; preparation of concrete for repair;
use of dry-pack mortar; procedure for the replacement of formed and un-
formed concrete; procedure for mortar replacements; repairs under seep-
age conditions; curing of repairs; and treatment for protection of concrete
against weathering.

In the field of repair and replacement, the sixth edition of the
Concrete Manual states:

"New information is presented in this edition on factors in-
fluencing strength of concrete. .. .- Precautions are given
for the use of calcium chloride where sulfate attack is ex-
pected because test results have shown that this admixture
may impair the resistance of concrete to this attack.

" _ More detail is included on the repair of cracks in
siphons and on the repair of concrete pipe. In many in-
stances better photographs and drawings have been used, "'

into a hopper from which the grout flows by gravity through a flexible
hose to the holes drilled through the lining. No attempt is made to raise
settled slabs into place, but if they are too badly cracked and have settled
an excessive amount, the slabs are removed backfilled with soil and re-
placed. The photograph below is a general view of the operation on the
West Canal.

The project advises that in addition to the equipment now mounted
on the low-boy a water supply tank will be added to the equipment in the
future. For further details of the equipment and its use write the Project

Construction:

The scaffold consists of a wooden platform and adjustable
legs, connected by removable 7/8-inch diameter steel rods, Held in
position by rope or a cable attached to a block and tackle, the plat-
form can be raised or lowered into the working position with a mini-
mum of effort and lost time.

The project advises that the scaffold can be constructed for
about $20.00 and is durable and sufficiently light in weight to be easily
moved from place to place.

PORTABLE ELECTRIC DRILL RAISES AND LOWERS GATES

Where electric power is available, the time consuming and
laborious task of raising and lowering gates by hand can be eliminated.
The device shown below and constructed by A. J. Phipps, Central Val-
ley Project, California, accomplishes just this, and is adaptable to
other hand-operated gates and hoists.

An electric
drill furnishes the
motive power and
an old Chevrolet
steering gear as-
sembly with a gear
reduction ratio of
7:1, transmits the
power to the orig-
inal gate-raising
mechanism, Di-
rection of the gate
travel can be re-
versed by attach-
ing the driving
mechanism to the
opposite side of the
original hand-crank-
“ing gear.

INTRODUCTION

This is release No. 12 of the Operation and Maintenance
Equipment and Procedures Bulletin, From material supplied by re-
gional, project, and field offices, this issue of the Bulletin has been
prepared in the Office of the Assistant Commissioner and Chief En-
gineer, Denver Federal Center, Denver, Colorado, by the Division
of Irrigation Operations, Our thanks to the people who have contrib-
uted the very worthwhile information.

In addition to the many suggested items for improvement in
equipment or procedures included in this issue, your attention is di-
rected to the article on page 12, the new edition of the Bureau of Rec-
lamation's Concrete Manual. This new edition, the Sixth Edition, is
the first published since 1949. Quoting from the new edition:

"Since publication of the fifth edition of the Concrete
Manual in 1949, the knowledge of the use and behaviour of
concrete has advanced in many important details. The text
of the fifth edition has been rewritten or supplemented to re-
flect the effect of these advancements on the practices of the
Bureau of Reclamation.

Release No. 11 of the Operation and Maintenance Equipment
and Procedures Bulletin (our last issue), was devoted to the subject,
"Good Concrete on Operating Projects." Aimed at our maintenance
problems, the release pointed out some of the advancements made
in concrete construction in accordance with the Sixth Edition of the
Concrete Manual. In fact, the subject matter of our last release
was prepared primarily by authors of the new Concrete Manual,
Material contained in the Bulletin necessarily was brief. Accord-
ingly, the new edition of the Concrete Manual contains much useful
information for construction and maintenance personnel interested
in concrete work.

The Operation and Maintenance Equipment and Procedures
Bulletin is circulated for the benefit of project operation and main-
tenance people. Its principal purpose is to provide a medium for ex-
change of operating and maintenance information, Reference in the
Bulletin to a trade name does not constitute an endorsement of a par-
ticular product and omission of any commercially available item does
not imply discrimination against any manufacturer. It is hoped that
labor saving or less costly equipment developed by the resourceful wa-
ter users will be a step toward commercial development of equipment
for use on irrigation projects in a continued effort to reduce costs and
increase operating efficiency.

Another suggestion from the
Tracy Operations Field Division,
Central Valley Project, California,
is the porcelain enameled metal
gauge marker for radial gates shown
in the photograph at left,

Mr. F. S. Icardi made the sug-
gestion and his idea was immedi-
ately adopted. The installation
shown is on a radial gate on the
Delta-Mendota Canal and provides
for a saving in annual painting costs,
It should have merit in similar in-
stallations on other projects.
