Detailed description of the invention
In order to make the object, technical solutions and advantages of the present invention clearer, below in conjunction with drawings and Examples pair
The present invention is used for the method for bridge construction in special formation and device is further elaborated.It should be understood that this place is retouched
The specific embodiment stated only in order to explain the present invention, is not intended to limit the present invention.
In one embodiment, as shown in Figure 1, it is provided that a kind of method for bridge construction in special formation, wherein,
The present embodiment is chosen vibrating liquefaction sandy strata and carries out example.It should be noted that special formation of the present invention does not limits
In vibrating liquefaction sandy strata, it is also possible to include profundal zone sand-pebble layer.Concrete the method comprises the following steps:
Step 100, cast anchor execution positioning action to crane barge, and guide table completes welding.
In the present embodiment, platform pipe pile foundation squeezes into employing crane barge, and crane barge is taken turns by 120t binary and fixed 1 200KN vapour
Car hangs to be made, and is mounted laterally cantilevered leading truck platform at hull, is used for fixing steel-pipe pile and steel pile casting.Crane barge location uses double
The hoist engine traction anchor line of body wheel corner is carried out.Crane barge location after, install and adjust leading truck, utilize total powerstation to steel-pipe pile,
Steel pile casting position is accurately positioned, and squeezes into riverbed section by section with vibratory pile driving hammer.
Step 200, then squeeze into steel-pipe pile and steel pile casting, complete the erection of work platforms.Wherein, squeeze into steel-pipe pile and steel protects
Cylinder includes: perform to squeeze into operation by crossing location to steel-pipe pile and steel pile casting.The buried depth of steel pile casting processes.Liquefaction sandy strata
Steel pile casting buried depth first does not the most all reach requirement, uses the little impact of 50KN to bore, by thin for powder at steel pile casting footing before formally spudding in
Sand is compacted, then uses pile hammer to continue injection steel pile casting, buried depth 4-6m.Impact brill is used to continue to creep into steel pile casting footing
About 4m, uses rotary rig instead and creeps into, it is to avoid string water spillage phenomenon occur.
In the present embodiment, aquatic work Platform Designing load is 2 GQ-12 rigs, 2 set mud circular slurry making ponds, experience
Calculate platform pipe pile foundation, be made up of 18 steel-pipe piles, steel-pipe pile center distance 3.14,3.54,4.00m, single pile design bearing capacity
200KN, use 700KN vibratory pile driving beat into.Further, after steel-pipe pile has been beaten, top is evened up by designed elevation and slots,
Welding ∠ 75*75*6 links angle steel, lays steel plate, and thickness 5cm forms work platforms, and welds railing at platform outer edge, really
Ensure safety.
Further, mud circulating system is made up of mud pit, sedimentation tank, circulating pump and is formed by 1cm Plate Welding, outward
Shape size 5m*3m*1.5m, is fixed on work platforms, and cell body bottom is stayed and set 50cm*40cm movable rows cinder notch.
Step 300, processes flour sand at steel pile casting footing, and performs steel pile casting spreading and squeezed into operation by pile hammer.
In the present embodiment, before rig pierces fine sand layer with creep into casing footing, mud balance to be strengthened, coagulate the soup
Mud, the rate of penetration that slows down controls at 80cm/h, after this section of 3-4m, changes middling speed into and creeps into.Suitably adjust head height, dimension
Hold head difference the most stable, reduce the impact of river breathing, communicating pipe can be used if desired；Occur during collapse hole certain at collapse hole
The interior clay of altitude range mixes the backfill of a small amount of cement, then bores little stroke (40-50cm) with impact and creeps into, by collapse hole location.
Step 400, rig para-position is spudded in, and is performed clear hole and concrete perfusion operation.Wherein, selecting of rig model,
With past construction experiences, geological prospecting rock stratum hardness, fine sand layer mechanics are specific etc. determines, the present embodiment uses GQ-12 type liquid
Pressure rotary rig, and include after the step spudded in of rig para-position: adjust rig drilling parameter and mud index.Wherein, bore
Enter parameter as shown in the table:
Wherein, the outfit of hand-hole mud.Thin silt at vibrating liquefaction is constructed, and the control of Mud Technology index is very
Important, after overtesting, use the cellulose participating in potter's clay weight 5 ‰, the Caustic soda of 6 ‰, the R425 cement of 4 ‰.Mud during perforate
Slurry proportion 1.23-1.35, viscosity 26-28s, sand factor 4%, colloidity > 95%.Further, boring selects single waist three to plough
Type cut drill, direct circulation creeps into, the clear hole of direct circulation, hand-hole mud balance 1.15-1.2, viscosity 19-20s, final clear hole, mud
Slurry proportion 1.15, viscosity 19s.
Step 500, improves steel pile casting and hangs with assembling group, complete the repacking of work platforms.
Step 600, assembles and spells steel jacket box, and complete the installation of guide device.
In the present embodiment, use group to hang spelling, sinking steel jacket box, save Large-scale Hoisting equipment, with form
The oriention benchmark that pile foundation is sunk as steel jacket box, is not required to rectify a deviation specially, entangle torsion operation, shortens the duration.
Further, steel jacket box is designed as rectangular band knuckle bivalve truss-like, cushioning sealing adhesive tape between joint, block, uses
Bolt connects.Casing is overall according to 2-4m height merogenesis, often saves and to design its intensity, avoids least favorable with maximum water pressure at this
Positional symmetry piecemeal, often joint steel jacket box be divided into 8 pieces and 8 separations, in order to assembly, transport and sink.Further, steel bushing
Before case spelling, connect high drilled pile steel pile casting, horizontal-associate I36b I-steel, hang 100KN jack composition group and hang.Steel jacket box crane barge exists
After assembly is good on lower floor's platform, group hangs to mention and put in water, utilize buoyancy assembled section by section on the water surface, water filling suck sediment subsidence,
The back cover that draws water after putting in place carries out cushion cap associated construction.
Step 700, performs water filling, the operation of suck sediment subsidence, and removes group and hang.
Step 800, performs to throw the fence operation of sheet gabion, and completes to irrigate cutting shoe concrete and back cover operation.
Step 900, draws water and performs next step working procedure.
Above-mentioned method for bridge construction in special formation, first cast anchor execution positioning action to crane barge, and to guiding
Platform completes welding；Squeeze into steel-pipe pile and steel pile casting again, complete the erection of work platforms；Process flour sand at steel pile casting footing, and
Perform steel pile casting spreading and squeezed into operation by pile hammer；Rig para-position is spudded in, and performs clear hole and concrete perfusion operation；Improve steel
