Embodiment
As shown in Figure 1, underwater pump tube of the present invention comprises one section horizontal pipe 1 and two sections vertical pipelines 2, and horizontal pipe is connected with vertical pipeline by the elbow 11 at two ends.Horizontal pipe and vertical pipeline have been arranged side by side many groups.As shown in Figure 2, the anchor ear 3 that is provided with by the interval between each horizontal pipe is connected and fixed and is one, and the anchor ear bottom is provided with a plurality of vertical pins 31.Vertical pipeline is also fixedlyed connected with the truss 4 of steel except connecting by anchor ear.
The underwater pump tube method of construction of the embodiment of the invention may further comprise the steps successively:
1, pump line processing, whole pump line divides three parts to process, and comprises the vertical section (length is respectively about 16m) at horizontal segment (comprise the elbow at two ends, be about 110m) and two ends.Pump line adopts liquid seamless steel pipe processing and fabricating, and the straight-tube portion specification is φ 159*5mm, and the bent tube section specification is φ 159*6mm, the pump line butt joint adopts plays earlier the groove butt welding, add the long sleeve pipe of 40cm again and weld, to guarantee the seal of whole pump line, the sleeve pipe specification is φ 175*5mm.Carry out the pump line waterproof test after machining.
2, pump line is fixed, in order to guarantee the safety coefficient of concrete in course of conveying, and disposable laying 6 road pipelines, the 2 tunnel normally use, and 4 the tunnel is standby.For the global stability that increases multiple-way duct and the whole lateral stiffness in the installation process, the rigidity anchor ear is set near each joint one, 6 road pipelines are fixed into an integral body, and the anchor ear spacing is not more than 12m.The two ends vertical duct also is fixed on vertical duct on the Steel Truss except that being provided with on request the anchor ear, does not destroy in the process of lifting to guarantee vertical duct.Simultaneously, for the ease of the lifting of two ends vertical pipeline, the vertical pump line with two ends is horizontally fixed on Steel Truss earlier, during lifting, directly lifts truss, to increase lifting rigidity, guarantees the quality of pump line.
C. the pump line annex is installed, after pump line is fixedly finished, and hanger, the draw ring that stays rope and the colligation keg float of each suspension centre of welding on anchor ear.Floating drum all is provided with 1 group on each anchor ear, 3 every group.The keg float of 36 φ 56 * 88cm is set altogether.
D. pump line afloat joining, the both fixed positions at the pump line two ends respectively set 1 group of dowel pile, so that carry out pump line location and fixing.
Horizontal pipe adopts many crane gears, according to the position of each suspension centre of calculated in advance, carries out the slowly lifting synchronously of many suspension centres, and integral body hangs in the water.Utilize on the buoyancy of keg float and pump line self bubbles through the water column.
Fasten the two ends of horizontal pipe with the tow rope of the set position of tractor tug and two ends, the traction horizontal pipe is to specified position, traversing for preventing that pipeline is produced by flow action simultaneously, in the pipeline both sides hawser is set all, to avoid the pump line middle part to produce traversing, cause pump line stressed excessive, produce and destroy.For guaranteeing the stress balance of pipeline, hawser position, corresponding both sides is arranged on the same anchor ear of fixing tube.In the pipeline distraction procedure, crane barge is set in the water with the moving of pump line, in case special circumstances occur.After horizontal pipe enters the dowel pile position, carrying out interim fixing with dowel pile, lift vertical pipeline with crane gear respectively in pipe ends, is leading truck with the dowel pile, slowly transfers to the joint, docks with horizontal pipe.For accelerating field joint speed, guarantee this joint quality, the high undersea hydrostatic pressures pipe clamp is adopted in the joint butt joint, to and joint adopt quick high-strength sealing to handle.
E. the pump line installation in position after butt joint finishes, removes the keg float of colligation on pump line by the centre to the two ends symmetric solution.Allow horizontal pipe utilization deadweight sink, the vertical pipeline at pump line two ends adopts crane gear D1 to sink synchronously gradually simultaneously.Be to guarantee the conformity of two ends vertical pipeline and horizontal pipe subsidence velocity, utilize that crane barge D2 is provided with two suspension centres in the water on horizontal pipe,, and keep coordination with the vertical pipeline subsidence velocity at two ends with controlling level pipeline subsidence velocity.After pump line sinks down on the riverbed, all pipelines are carried out water filling simultaneously, make in the darker insertion riverbed of pin on the anchor ear, after water filling is finished, will fix between vertical pipeline, truss and dowel pile.
Carry out in the course of conveying of concrete at the underwater pump tube that utilizes method of construction of the present invention to install, underwater pump tube all is lubricated with mortar earlier before each the use, carries out concrete again and carries; After each use finishes, adopt cotton batting and column rotating wash bowl to clean pump line earlier, and then carry out hole clearly, repeat repeatedly, make the interior water full scale clearance of whole pump line with pressurized air.
