Problems solved by technology

However, this method requires traffic control, and the excavation of the surface will also destroy the original balance of ground stress. The construction period is long, and it cannot achieve rapid and continuous repair of pipeline misalignment.

Embodiment 1

[0047] like Figures 1 to 5 As shown in the figure, a pipeline dislocation repairing device includes a main support 1, which is provided with a ring-direction top-stretching component, and the ring-direction top-stretching component is connected with at least two strip-shaped thrust plates 4, all the The push plates 4 are evenly arranged in the circumferential direction around the main support 1, the length directions of all the push plates 4 are parallel to each other, and the annular push plate 4 drives all the push plates 4 to expand or expand synchronously in the radial direction. retract. The main support 1 is also provided with a walking mechanism 5 .

[0048] like figure 1 and 3 , the annular push-up assembly includes a radial push-up unit 3, the radial push-up unit 3 is in one-to-one correspondence with the push plate 4, the radial push-up unit 3 is connected with the main support 1 and the main support The corresponding push plates 4 are connected. The radial top...

Embodiment 2

[0061] A pipeline dislocation repair method, using the repair device of the first embodiment, the steps are:

[0062] Step 1. The repairing device is lowered to the bottom of the pipeline through the inspection well, and is moved by the roller 52 inside the pipeline to reach the dislocation joint b of the two pipeline units a. At this time, the two ends of the push plate 4 are are located on both sides of the dislocation seam b, such as Image 6 , 7 or 8 shown.

[0063] Step 2, the two hydraulic cylinders work synchronously, respectively push the corresponding thrust connecting rod 32, and the thrust connecting rod 32 pushes the outer support push rod 31, so as to make the push plate 4 expand outward, and gradually connect with the pipeline unit a. The inner walls are attached until the two ends of all the push plates 4 are respectively attached to the inner walls of the two pipe units a, and the alignment of the two pipe units a is completed. At this time, the dislocation s...

Abstract

The invention discloses a pipeline dislocation repairing method. The steps are as follows: a repairing device is installed, the repairing device includes a main support, a ring-direction top-stretching component is arranged on the main support, and the ring-direction top-stretching component is connected with a circumferential distribution At least two strip-shaped ejector plates, the annular ejector assembly drives all the ejector plates to expand or retract synchronously in the radial direction, and then the repair device is lowered to the bottom of the pipeline through the inspection well, and the repair device is moved to the two pipelines At the dislocation joint of the unit, the annular jacking component pushes all the ejector plates to open in the circumferential direction to align the two pipe units, and then grouting is performed at the joint, and finally the soil at the reset joint is removed from the outside of the pipeline. The body is grouted for reinforcement. Beneficial effects of the invention: since the reset work is performed in the pipeline, many inconveniences caused by hoisting and reset on ground excavation in the prior art are avoided, and the whole process has high repair efficiency, little disturbance to the road surface, and reduced cost.

Description

technical field [0001] The invention belongs to the field of underground pipeline maintenance devices, in particular to a pipeline dislocation repair method. Background technique [0002] In my country, underground space has been gradually developed and utilized, and urban water supply, sewage, rainwater pipes, etc. are all buried underground, forming an intricate underground pipe network. With the increase of the service life and the uneven settlement of the foundation, the spliced ​​pipes will inevitably be dislocated, causing the internal water resources to seep outward, wasting my country's precious water resources; in addition, the seepage water migrates in the soil foundation. The penetration force will also scour the soil foundation, weaken the bearing strength of the soil foundation, and cause voids under the pipeline; with the influence of the vehicle load above the pipeline or the self-gravity of the soil, the pipeline will further sink at the loose and void of the ...
