Even suddenly highway extension project across Overpass Bridge of Jingjiu Railway (K78+360.93-K78+597.05), overall length of bridge
236.12m, roadbed position setting abutment support pile is 64 total before away from 0#, 9# abutment, and top is connected by crown beam, left and right half range
Crown beam is connected by coupling beam.The long 23m of support pile, diameter 1m, every support pile design amount of concrete is 18.06m3, using reacting cycle
Churning driven construction.
Construction site is located at before abutment on existing 13m broad way face, and road surface is that embankment embankment is taken away from 10 meters of ground level
The mode of half range construction, left half range are normally open to traffic.Construction site is narrow, and scene, which can not excavate, builds mud pit, and mud is easy
Road surface and widened section roadbed are polluted, left half range driving is influenced, it has been decided through consideration that production one mobile mud pit, for solving
The certainly problem.
(1) according to construction condition, movable type mud pit size is determined；
Mobile mud pit design meets the following conditions:
1, known single support pile design concrete is 18.06m3, to recycle convenient for mud, mobile mud pit volume is not
18.06m can be less than3。
2, mobile mud pit cannot be filled, and mud is avoided to overflow pollution road surface and widening road bed.
3, width of roadway is narrow, and construction machinery is numerous, therefore mobile mud pit length is unsuitable too long, in order to avoid influence equipment
It turns and turns around.
4, for convenient for sidewalk transport, mobile mud pit width be should not be too large.
5, consider tire bearing capacity, mobile mud pit is integrally self-possessed cannot be excessive.
6, mud is considered to lateral wall pressure, and mobile mud pit height should not be too large.
7, it is convenient for mud sediment, partition 13 need to be set；13 height of partition should be 0.5m lower than 11 height of cabinet.
8, a pair of of water outlet is set, is recycled for mud；Water outlet height cannot be too low, in order to avoid mud sediment accumulated plugging
Intake-outlet.
It is 3 meters wide in conclusion 6 meters long using the production of 0.5cm thickness iron sheet, high 1.5 meters of mud pit carry out mud circulation and
Precipitating, water outlet diameter 15cm.
(2) mobile bracket 244 is arranged；
Using two 200*200HW fashioned iron as girder, 2.6 meters of center spacing.Top transverse weld 10# channel steel 2112
Root, spacing 0.5m, both ends cantilever 20cm.The base plate drilling at 0.5 meter of girder H profile steel cantilever and span centre position, anchor bolt fix 6
Overweight shaped iron core rubber universal wheel 24 realizes 360 ° of movements of mobile device.The setting of girder one end forms pull rod using steel-pipe welding,
For drawing.Iron sheet cabinet 11 is formed a whole with mobile device.
(3) bindiny mechanism；
Limited block 231 uses reinforcing bar；First pipe fitting 232, the second pipe fitting 233, third pipe fitting 234, the 4th pipe fitting 235 are adopted
Use steel pipe.
(4) using and shifting for mud pit is moved；
Using the characteristic of 60 ° of universal wheel mobile rotations when marching into the arena, the adjustment of mud pit position is carried out, can be the half range
All support piles of abutment carry out mud circulation.
Mud pit at 1.5 meters of kingpost cantalever in use, be respectively set 4 screw jack, by integral raising to girder
For bottom plate away from ground about 40cm, the 4 0.5 meter long 400*400 lumps of wood 25, which is filled in jack position, keeps bracket 244 hanging, then drops
Lower jack.The lumps of wood 25 is used to support mobile mud pit self weight and mud load.
Drilled pile reacting cycle construct when, mud is discharged into mud pit from drilling machine, precipitated in sedimentation basin, when mud be higher than every
It after plate 13, spills over and follows stock tank, the mud after precipitating is discharged among drilling by water outlet, to recycle.When being poured concrete,
The mud overflowed in hole is pumped into the sedimentation basin of cabinet 11 using mud, if mud is excessive in sedimentation basin, should use mud of technological requirement
Mud in mud pit is cleared up.
After the completion of construction, slurry liquid in cabinet 11 is taken away using mud of technological requirement and is discharged into designated position；Cooperated with excavator
Manually, the inner remaining mud of cabinet 11 is shoveled out, transports to designated position stacking with dump truck and dries；When an abutment support pile
After the completion of construction, cabinet 11 is emptied, the lumps of wood 25 is extracted with very heavy top support, universal wheel 24 is made to land, using traction device by case
Body 11 is transferred to next abutment, and cooperation carries out the drilling construction of support pile.
