Description

Technical Field

[0001] The utility model relates to the technical field of gas pipelines, and in particular to a device for reinforcing high-pressure gas pipelines. Background Art

[0002] As an important part of urban infrastructure, pipelines mainly bear the function of connecting key equipment such as pumps, valves, and control systems. These pipelines crisscross the city, forming a huge network that provides solid support for the normal operation of the city. Urban underground pipelines are an important "lifeline" that is indispensable for urban operations. They cover multiple fields such as gas, electricity, industrial communications, and related ancillary facilities, together forming a complex and sophisticated pipeline network system in the city's underground space. These underground pipelines not only carry the task of transmitting urban energy and information, but are also directly related to the quality of life of urban residents and the sustainable development of the city. Therefore, strengthening the construction, management and maintenance of urban underground pipelines to ensure their safe, reliable and efficient operation is of great significance to safeguarding the normal order of the city and the vital interests of residents.

[0003] During the installation of high-pressure gas pipelines, it is first necessary to accurately dig out a trench that meets the design requirements. This step is crucial because it not only determines whether the pipeline can be laid smoothly, but is also directly related to the safety of the subsequent use of the pipeline. During the excavation process, the relevant safety regulations and operating procedures will be strictly followed to ensure that the depth, width and slope of the excavation meet the design requirements. After the trench is excavated, the next step is to lay the pipes. According to the pre-designed pipeline direction and layout, the high-pressure gas pipelines are placed in the trench one by one. During the pipe laying process, attention will be paid to the connection and fixation of the pipelines to ensure that each section of the pipeline is firmly connected and accurately positioned.

[0004] After the pipes are laid, the last step is backfilling and tamping. This process also requires meticulous operation, because the density of the backfill directly affects the stability and safety of the pipeline. According to the requirements of the specification, backfill and tamp the soil layer by layer to ensure that there are no gaps or looseness around the pipeline. Through this series of rigorous installation steps, we can ensure that the installation quality of the high-pressure gas pipeline meets the requirements and lay a solid foundation for subsequent use and maintenance.

[0005] At present, the reinforcement structure of high-pressure gas pipelines and their external pipelines has not been widely used. However, with the intensive development of urbanization, shield machine construction has become more and more frequent around the built pipelines. The excavation construction of such shield tunnels often causes settlement of the strata around the tunnel. This settlement phenomenon will not only cause deformation of the pipeline, but may even cause damage to the pipeline, and then cause serious consequences such as gas leakage or even explosion, which will have a great impact on society. The patent application with publication number CN117267470A discloses a municipal construction pipeline protection device, the synergistic effect of the upper ring and the lower ring of the device is intended to protect the pipeline placed in the cavity from the direct impact of the traffic load on the road, thereby effectively preventing the pipeline from rupture, damage and other adverse situations. However, this technology only discloses a form of clamp protection, the entire device lacks effective support, and the structure is not stable.

[0006] In view of the above problems, it is urgent to propose a reinforcement device specifically for high-pressure gas pipelines. This device aims to reduce the impact of shield construction on pipelines through effective reinforcement measures and ensure the safety and stability of pipelines. This can not only increase the service life of gas pipelines, but also reduce safety risks such as gas leakage, thereby ensuring the safety of urban residents and the stable development of society.
