Description

Technical Field

[0001] The invention relates to the field of subway construction equipment, and in particular to a pipeline support system for subway construction. Background Art

[0002] Subway, which is the abbreviation of underground railway, originally refers to the urban rail transit system running underground. However, with the development of urban rail transit systems, subways are sometimes laid on the ground due to the construction environment. Subway is a fast and large-capacity urban rail transit mode that is gradually developed along the form of underground railway systems and is tractioned by electricity.

[0003] During the construction of the subway, the pipeline system is an essential construction project to ensure the normal drainage and water supply. During the pipeline laying, in order to improve the stability and seismic performance of the pipeline, seismic supports are generally used to fix and support it. The seismic supports limit the displacement of the auxiliary electromechanical engineering facilities, control the vibration of the facilities, and transfer the load to various components or devices on the bearing structure, thereby improving its use strength and overall service life.

[0004] However, when using traditional seismic supports for pipes, it was found that since there are many specifications for the sizes of pipes laid in the pipeline system, when using seismic supports to support them, every time a pipe of a different size is encountered, the clamps used to clamp the pipes need to be replaced with appropriate types. The parts on the entire seismic support are not unified, which makes the laying process time-consuming and cumbersome.

[0005] Therefore, those skilled in the art provide a pipeline support system for subway construction to solve the problems raised in the above background technology. Summary of the invention
