The butt end of disk, pipeline 2 to be installed is equipped with ring flange, further comprising the steps of: S1: using air bag 6 by pipe laying 1
Butt end is lifted, and installs drawing device 10 and limiting device 11 in the butt end of the pipe laying 1；S2: it removes
The blind plate and sandboard of the butt end of pipe laying 1 carry out sedimentation of pouring water to pipe laying 1；S3: the progress of pipe laying 2 is treated
It pours water and settles and keep its pipeline 2 to be installed corresponding with the height of pipe laying 1 by the crawler crane 4；S4: it is described to
The butt end installs fixture of pipe laying 2, the fixture are equipped with idler wheel；S5: the steel wire penetrating of hoist engine 5 pipeline 2 to be installed
The fixture of butt end is simultaneously connect with the drawing device 10 of 1 butt end of pipe laying；S6: the wirerope of tensioning hoisting machine 5, drawing
Pipeline 2 to be installed is close to pipe laying 1 and is laterally and axially positioned by the progress pipeline of limiting device 11 until to be installed
Pipeline 2 fits with pipe laying 1；S7: coarse positioning is carried out by ring flange of the steel screw rod to both ends；S8: mounting flange
Matched fixing bolt is simultaneously tightened；S9: air bag 6 is sequentially discharged from 1 direction of pipe laying, sinking pipeline completes pipeline docking.
Air bag 6 is bound within the scope of the about 70m of the butt end of pipe laying 1, pipe laying 1 is sling using 6 multiple spot of air bag
Butt end, making the segment pipe, away from bottom about 1.5m, barge 3 is docked in the top of pipe laying 1, distance for lifting after sedimentation of pouring water
Butt end about 15m, the air bag 6 under barge 3 are bound in 1 two sides of pipe laying.
Concrete anchor block 7,1 butt end of pipe laying are equipped at the 1 butt end two sides about 5m of pipe laying
It is fixed on the concrete anchor block 7 by hawser, so that docking pipeline is maintained a relatively stable state, pipe laying 1
Butt end is equipped with multiple kentledges 9, and the drawing device 10 is two and is symmetrically set in first ballast of pipe laying 1
The two sides of block 9.
Contraposition adjustment is equipped between the ring flange of 2 butt end of the ring flange of 1 butt end of pipe laying and pipeline to be installed
Wirerope 12, contraposition adjustment wirerope 12 are being installed when pipeline 2 to be installed is close to 1 certain distance of pipe laying,
Hole location check and correction can be carried out to the flange hole at both ends.
The drawing device 10 includes support plate 101, the first fixed plate 102 and the second fixed plate 103, and described first is fixed
