Problems solved by technology

Especially for coal mining under the pipeline, the most commonly used method is to leave a protective coal pillar underground and reroute the surface pipeline: leaving a protective coal pillar is similar to coal mining under the railway. Although it can protect the pipeline well, it will waste a lot of coal. Resources are the cost; pipeline rerouting requires re-burying the pipeline, which greatly increases the cost of the pipeline
At present, there are not many studies and applications of protective measures for pipelines. Some experts have proposed the application of pipe lifting technology in goafs, which is to use lifting devices to adjust pipelines. Many, it is very unsuitable for implementation under various subsidence surface conditions, and it is difficult to meet the needs of production

Embodiment 1

[0021] Such as figure 1 and figure 2 As shown, this embodiment is an anti-mining deformation adjustment device for shallow buried gas pipelines, which includes an excavated pipe trench 1, a smooth backing plate 2 for supporting the pipeline, and an adjustable base for supporting the smooth backing plate 2. Seat 3, the smooth backing plate 2 is placed on the top of the adjustable base 3, the smooth backing plate 2 and the adjustable base 3 are both located in the excavated pipe trench 1, and the smooth backing plate 2 and the adjustable base 3 form a support support for the pipe. Excavating the pipe trench 1 refers to digging out the covering layer of the pipe, and forming a certain excavation space, which facilitates free relative movement between the pipe and its support.

[0022] In this embodiment, the smooth backing plate 2 is a wooden backing plate, a porcelain backing plate or a rectangular plate made of other materials with a smooth upper surface, and the pipeline ca...

Embodiment 2

[0024] Such as image 3 As shown, in this embodiment, a shallow-buried gas pipeline anti-mining deformation adjustment device includes excavation pipe trench 1, a smooth backing plate 2 for supporting the pipeline, and an adjustable base for supporting the smooth backing plate 2. Seat 3, the first jack 6 for supporting the smooth backing plate 2 and the second jack 7 for supporting the smooth backing plate 2, the smooth backing plate 2 is placed on the top of the adjustable base 3, the first The first jack 6 and the second jack 7 are located on both sides of the adjustable base 3 respectively, and the smooth backing plate 2, the adjustable base 3, the first jack 6 and the second jack 7 are all located on the Excavate the trench 1. Excavating the pipe trench 1 refers to digging out the covering layer of the pipe, and forming a certain excavation space, which facilitates free relative movement between the pipe and its support. The parameters of the first jack 6 and the second ...

Abstract

The invention discloses a trample-deformation-resistant adjusting device for a shallow-buried gas pipe. The trample-deformation-resistant adjusting device for the shallow-buried gas pipe comprises an excavated pipe ditch, a smooth surface base plate and an adjustable base seat, wherein the smooth surface base plate is used for supporting the pipe, and the adjustable base seat is used for supporting the smooth surface base plate. The smooth surface base plate is placed on the top of the adjustable base seat, and both the smooth surface base plate and the adjustable base seat are located in the excavated pipe ditch. The trample-deformation-resistant adjusting device for the shallow-buried gas pipe is simple and reasonable in structure and capable of overcoming the impact on the shallow-buried pipe from coal mining ground surface depression and horizontal migration and various deformations, and preventing the pipe from being damaged by ground surface movement and deformations. In addition, construction operation is simple, convenient and efficient, the problems that pipe resource recovery through coal depression areas and pipe safety are solved, and a novel approach is provided for pipe compressed coal mining.

Description

technical field [0001] The invention relates to a pipeline adjustment device, in particular to an anti-mining deformation adjustment device for a shallow buried gas transmission pipeline. Background technique [0002] The exploitation of underground resources will lead to different degrees of surface subsidence, which in turn will have different degrees of impact and damage on surface objects (buildings, railways, pipelines, etc.). Especially for coal mining under the pipeline, the most commonly used method is to leave a protective coal pillar underground and reroute the surface pipeline: leaving a protective coal pillar is similar to coal mining under the railway. Although it can protect the pipeline well, it will waste a lot of coal. Resources are the cost; pipeline rerouting requires re-burying the pipeline, which greatly increases the cost of the pipeline. At present, there are not many studies and applications of protective measures for pipelines. Some experts have pro...
