Adjustable protection device for gas pipe

Abstract

The invention relates to an adjustable protection device for a gas pipe. The device comprises the gas pipe, wherein a base is arranged under the gas pipe; a steel plate is pre-embedded on the top of the base and provided with a door-shaped frame; the upper end of the door-shaped frame is provided with a fixing nut and connected with a lead screw; the lower end of the lead screw is connected with a steel protection pipe; and the gas pipe passes through the steel protection pipe. Thus, the safety of the pipeline of the gas pipe can also be ensured during serious ground surface subsidence. The device has the characteristics of ensuring the safety of the pipeline during underground engineering construction and reducing safety risk, along with higher convenience, higher safety and short pipeline reconnection time. The device can be widely used as the adjustable protection device for pipelines during the underground engineering construction needing to pass through the gas pipe, such as tunnels, underground passages, underground stores and the like.

Description

technical field [0001] The invention relates to an adjustable protection device for gas pipes, in particular to an adjustable protection device for gas pipes used as an adjustable protection device for pipelines when passing through gas pipes in tunnels and other underground projects. When the uneven settlement of the pipeline is caused, the pipeline can be adjusted in time through the adjustment device to effectively ensure the safety of the pipeline. Background technique [0002] When the gas pipe is passed under the underground project, the settlement and deformation of the pipe will be caused to varying degrees. In severe cases, the pipe will break and cause explosions and other accidents. Afterwards, the pipeline is relocated to the section of the underground building that has passed through, and the ground surface within the scope of the pipeline is reinforced by grouting or reinforced tunnel pre-grouting. The above methods are relatively traditional, and the existing ...

[0002] When the gas pipe is passed under the underground project, the settlement and deformation of the pipe will be caused to varying degrees. In severe cases, the pipe will break and cause explosions and other accidents. Afterwards, the pipeline is relocated to the section of the underground building that has passed through, and the ground surface within the scope of the pipeline is reinforced by grouting or reinforced tunnel pre-grouting. The above methods are relatively traditional, and the existing problems are: 1. The pipeline will be relocated Greatly increase the number of projects, resulting in a waste of resources. At the same time, it takes a long time to relocate the pipeline, which causes inconvenience to the production and life of the surrounding users: 2. The method of pre-reinforcement around the pipeline or strengthening the pre-reinforcement of the tunnel is often not available due to various factors such as technology achieve the desired effect

3. It is impossible to intuitively reflect the settlement and deformation of the pipeline, and there are great safety risks in the construction process
