Embodiment 1

[0038] Such as figure 1 , figure 2 , image 3 As shown, the first repairing device includes a top plate 9, a first clamping plate 8, an oil cylinder 11, and a first advancing cutterhead unit 12, and the second repairing device includes a second clamping plate 13 and a second advancing cutterhead unit 14. The top plate 9 and the second splint 13 are connected and fixed by the pull rod 1; the cylinder block of the oil cylinder 11 is fixed on the first splint 8, and the piston rod 10 of the oil cylinder is fixedly connected with the top plate 9; The first splint 8 drives the steel mold 7 to advance, and the steel mold 7 pushes the first advancing cutterhead unit 12 ; the second splint 13 drives the second advancing cutterhead unit 14 to advance. Wherein, in order to put the pull rod better, one end of the pull rod is detachably connected to the top plate, and the other end of the pull rod is detachably connected to the second splint.

[0039] It should be noted that, in order...

Embodiment 2

[0052] The difference from Embodiment 1 is that the first repairing device and the second repairing device are arranged symmetrically, and the movement state of the oil cylinder is opposite to that of the second oil cylinder.

[0053] Such as Figure 4 As shown, the second repair device also includes a second oil cylinder and a second top plate, the cylinder body of the second oil cylinder is fixed on the second splint, and the piston rod of the second oil cylinder is fixed on the second On the top board (not marked in the figure), the second top board is detachably connected to the pull rod.

[0054] The use of oil cylinders on both sides can effectively prevent the oil cylinder on one side from being unusable due to failure, while the oil cylinder on the other side can still be used, which effectively improves the construction efficiency and reduces the impact of construction equipment failure on the construction process. In addition, the use of oil cylinders on both sides ...

Abstract

The invention discloses a pipeline counter-pulling and repairing device and a repairing method thereof. The pipeline counter-pulling and repairing device comprises a first repairing device and a second repairing device, wherein the first repairing device and the second repairing device are arranged at the two ends of a pipeline to be repaired respectively, the first repairing device and the secondrepairing device move oppositely, and the first repairing device and the second repairing device are connected through a counter-pulling device. Compared with the prior art, the pipeline counter-pulling and repairing device and the repairing method thereof have the advantages of being high in repairing efficiency, good in repairing quality, and low in repairing cost.

Description

technical field [0001] The invention relates to the field of repairing underground pipe networks, in particular to a pipe pulling repair device and a repairing method thereof. Background technique [0002] At present, in the renewal and repair of underground pipelines, many construction techniques such as trenchless expansion (expansion) pipes, rammed pipes, interspersed pipes, and lined pipes are used. A rough description is as follows: [0003] 1. Non-excavation pipe expansion (pipe expansion) process: non-excavation pipe expansion (pipe expansion) process is a hydraulic power equipment that connects, transports, and pulls back the quick-loading rod, and pulls the cutting head, While splitting and expanding the old pipe, the expansion head squeezes the old segment into the soil around the old pipe, drags the new pipe connected behind the expansion head to the required position, and realizes the process of replacing the old pipe. [0004] 2. Non-excavation and intersperse...
