Abstract
The invention discloses a mounting and construction method of U-shaped tunnel pipelines. The method comprises the following steps of: mounting pipelines of a left inclined shaft section firstly and meanwhile, carrying out pipeline transportation and distribution of a level section; after the pipeline transportation and distribution of the level section is finished, mounting pipelines of a right inclined shaft section; and finally, connecting the heads on the level section to run through, wherein the pipeline mounting of the inclined shaft sections comprises the following steps of: laying a light rail through the whole course at the bottom of the tunnel; then embedding a ground anchor, fixing a winding machine and beginning to excavate a working pit; mounting a hoop and a sled on a pipeline; connecting a pulley block with the ground anchor, the pipeline, the loop and the winding machine; ensuring that the pipeline downwards slides along the light rail through the sled until the upper port of the pipeline arrives at the working pit; then continuing to mount another pipeline; and repeating in such a way until the inclined shaft pipelines and the level pipelines are butt jointed. In the construction method, the operations of welding, flaw detecting and joint repairing aiming at the inclined shaft pipelines are all finished outside the port of the tunnel, thereby avoiding the construction in the tunnel, improving the construction safety, reducing the labor intensity and being beneficial to improving the welding quality, shortening the construction period and saving the construction cost.
Description
Technical field
The present invention relates to a kind of construction method of installation of large diameter pipeline, the U type tunnel pipelines construction method of installation that particularly a kind of lower curved section is long.
Background technique
At present, piping erection for U type tunnel, usually adopt the method for construction of in the tunnel, installing by root from lower to upper, pipeline group is mended, welding, flaw detection, repaired mouth and is hindered construction and all finish at tunnel internal, and there is following shortcoming in this method: (1) workmen's whole process is carried out the piping erection construction in the tunnel, potential safety hazard is bigger, in case it is not smooth to occur ventilating, roll into foreign matter or landslide, security incident will take place, naked hole section and first section construction safety problem are especially outstanding; (2) humidity is bigger in the tunnel, influence welding largely and repaired mouth quality; (3) in the tunnel, be subjected to spatial constraints, can't be by machinery, work efficiency is very low, and construction period is longer relatively, and construction cost also will increase relatively; (4) workmen's materials hauling, equipment on foot about, run out of space.
Summary of the invention
For solving in the existing U type tunnel pipelines construction method of installation, workmen's whole process is installed in the tunnel, and potential safety hazard is big, long in time limit, the problem that installation quality is difficult to guarantee the invention provides a kind of U type tunnel pipelines construction method of installation, and the pipeline welding of lower curved section is finished outside the tunnel.
For solving above technical problem, a kind of U type tunnel pipelines construction method of installation provided by the present invention, U type tunnel comprises left lower curved section, gallery section and right lower curved section, this method of construction comprises the steps: to carry out earlier the piping erection of left lower curved section, carry out the pipeline fortune stringing of gallery section simultaneously, after gallery section fortune stringing finishes, then carry out the piping erection of right lower curved section, connect at gallery Duan Liantou at last; (1) the omnidistance guiding device of laying light rail as the pipeline downslide in the bottom of tunnel lower curved section; (2) bury the earth anchor that can carry pipeline downslide load underground in the place ahead, tunnel face, and in position fix winch; (3) outside the tunnel face, excavate working pit; (4) anchor ear is installed on prefabricated tube section, anchor ear below is fixedly connected with sled, and described sled and described light rail are suitable and can slide along light rail; (5) form head pulley group and auxiliary pulley group respectively by static pulley, movable pulley and wire rope, the static pulley of two sheave block all is connected on the earth anchor, the movable pulley of head pulley group is connected with the anchor ear of pipeline, and the traction end of head pulley group wire rope is connected to winch and is drawn by winch; (6) prefabricated tube section glides along light rail by sled, controls its gliding speed and distance by winch, arrives the working pit place until the prefabricated tube section upper end-hole and stops; (7) continue to install a pipeline, the group of finishing two pipelines at the working pit place is successively mended, welding, flaw detection and repaired mouth and is hindered; (8) pipeline that welding is good continues to slide in inclined shaft, continues to install a pipeline; (9) after the wire rope of winch is discharged into safe length, use the auxiliary pulley group to draw prefabricated tube section in the tunnel face temporarily, rope traction end with a digging machine traction auxiliary pulley group is fixed prefabricated tube section, after again the head pulley group being decontroled withdrawal, again be bundled in the top of prefabricated tube section, draw the traction end of head pulley group wire rope after the wire rope of winch is regained again, carry out the welding of next root pipeline again and transfer construction, so alternately back and forth, dock with the gallery pipeline until the inclined shaft pipeline.
With respect to prior art, the present invention has obtained following beneficial effect: (1) has changed the method for construction of installing by root from lower to upper, makes the piping erection of left lower curved section and the pipeline fortune stringing of gallery section to carry out simultaneously, has shortened the duration; (2) group of lower curved section pipeline is mended to hinder to, welding, flaw detection and repaired mouth and is all finished outside the tunnel, has significantly reduced the activity duration of workmen in the tunnel, the Security that has greatly improved tunnel construction; (3) workmen mends to hinder to the welding of pipeline, flaw detection, repaired mouth and all finishes in the working pit the tunnel face outside, avoided round on foot on the slope in the tunnel, operated, and has also avoided the frequent displacement of welding, defect-detecting equipment; (4) compare with the high humidity environment in the tunnel, help improving welding and repaired mouth quality; (5) prefabricated pipeline can improve work efficiency by machinery outside the tunnel face, shortens construction period, saves construction cost; (6) reduce workmen's working strength, significantly reduce workmen's materials hauling, equipment on foot about.
As improvement of the present invention, be welded to connect whole between each sled by steel part, the end socket device of the minor details lower end mouth of the anchor ear of the minor details of pipeline and pipeline connects into integral body.Can prevent from like this to be shifted between pipeline and the anchor ear, avoid sled to move and the pipeline downslide.
As another kind of improvement the of the present invention, be provided with the rubber protective layer between described anchor ear and the described prefabricated tube section.Slide in the process at prefabricated tube section, the rubber protective layer can effectively be protected pipeline anticorrosion coating.
