Description

Technical Field

[0001] The present application relates to the technical field of pipeline laying, and more specifically, to a gas pipeline laying mechanism. Background Art

[0002] When the gas pipeline is installed in the municipal construction trench, a casing is generally set on the outside of the gas pipe body, and anti-corrosion and flexible materials are filled in the casing. Then the gas pipeline is directly laid and installed in the municipal construction trench through the casing, and then backfilled with soil. If multiple pipelines are buried in the municipal construction trench at the same time, the pipelines are easily laid in a chaotic manner. Generally, a row seat is required to arrange and install them in an orderly manner. The existing public technology number CN220037629U proposes a gas pipeline laying mechanism. The device has a simple structure and can achieve unevenness by setting an arc-shaped installation plate. The installation and fixation of the whole ground or the ground position with insufficient supporting force, and the triangular supporting area is set up, so the support is stable and convenient for laying pipelines. With respect to the above-mentioned related technologies, the utility model inventor believes that there are still the following defects: when the pipeline laying mechanism in the comparative literature lays multiple pipelines at the same time, there is no limiting mechanism between the pipelines, which leads to disordered pipeline laying and insufficient stability. Moreover, the gas pipeline is buried underground and the humid underground environment will cause pipeline corrosion. The pipeline protection is poor and the service life is short. In view of this, we propose a gas pipeline laying mechanism. Utility Model Content
