Therefore, when laying the cable pipe, it also saves time and effort and improves the construction efficiency.

Description

Technical Field

[0001] The present invention relates to the field of building materials, and more specifically, to a pipe gallery structure. Background Art

[0002] A pipe gallery, also known as an integrated urban underground pipeline corridor, is to build a tunnel space underground in the city, integrating various engineering pipelines such as electricity, communication, gas, heating, water supply and drainage, etc. It is equipped with special inspection openings, hoisting openings and monitoring systems, and implements unified planning, unified design, unified construction and management. It is the "lifeline" of the important infrastructure to ensure the operation of the city.

[0003] Pipe galleries are generally divided into prefabricated and cast-in-situ types. The prefabricated type is suitable for mature cities, while the cast-in-situ type is more suitable for newly built cities because it has a greater impact on the ground. Inside the pipe gallery, there are living pipe support piers and cable pipe brackets. After the prefabricated pipe gallery is docked, the corresponding pipes will be further installed and laid. When laying the living pipes, hot melt butt welding is required to ensure the sealing between the pipes. However, the internal space of the pipe gallery is limited, and it is more troublesome to construct the pipe hot melt butt welder inside the pipe gallery with limited space. Moreover, it is necessary to enter each pipe gallery one by one to construct and dock the pipes that need hot melt butt welding, which is more troublesome. The current living pipe support piers cannot perform the function of translating the pipes. Therefore, it is urgent to improve the living pipe support piers of the pipe gallery. Summary of the Invention

[0005] Aiming at the problems existing in the prior art, the purpose of the present invention is to provide a pipe gallery structure, which only needs to perform the welding construction of the pipes at the inlet of the pipe gallery at the outermost end. After the welding is completed, the pipes are pushed forward, and the pipes move on the pipe moving rollers with small resistance, which improves the working efficiency during pipe laying and has stronger practicability.

[0006] 2. Technical Solutions

[0007] To solve the above problems, the present invention adopts the following technical solutions.

[0008] A pipe gallery structure includes a single pipe gallery, a living pipe support pier and a cable pipe bracket. The living pipe support pier is arranged on the bottom side inside the single pipe gallery. The cable pipe bracket is fixed on the inner wall of the single pipe gallery by bolts. Through holes are symmetrically opened inside the living pipe support pier, and support rods are inserted at positions corresponding to the through holes of the living pipe support pier. A roller shaft is placed between the two support rods, and a pipe moving roller is nested outside the roller shaft. The pipe moving roller and the roller shaft are movably connected through bearings.

[0009] Further, installation grooves are evenly formed inside the cable pipe support bracket, and cable pipe moving rollers are installed inside the installation grooves. The cable pipe moving rollers and the installation grooves are movably connected through rotating shafts.

[0010] Further, a pipeline support groove is formed at the top end of the domestic pipe support pier, and the top surface of the pipeline moving roller is 0.5 - 1 cm higher than the lowest end of the pipeline support groove.

[0011] Further, support flanks are symmetrically arranged on both sides of the cable pipe support bracket, and the support flanks and the cable pipe support bracket are of an integral structure.

[0012] Further, a cable pipe baffle is arranged at one end of the cable pipe support bracket, and the cable pipe baffle and the cable pipe support bracket are of an integral structure.
