Description

Technical Field

[0001] This application relates to the field of municipal pipeline protection technology, and in particular to a municipal pipeline protection device. Background Technology

[0002] Various pipelines, such as power, communication, gas, water supply, and drainage pipes, are laid under municipal roads. As buildings and roads are continuously constructed in the city, it is necessary to excavate the road surface, then bury the pipelines underground for connection, and finally backfill with soil.

[0003] A search revealed a Chinese patent disclosure for a municipal pipeline protection device (authorization announcement number CN222215146U), comprising a protective pipeline. The protective pipeline has an internal bottom support, the bottom of which matches the internal shape of the protective pipeline. Multiple U-shaped cable trays are positioned above the bottom support. The bottoms of the cable trays are fixedly connected to the bottom support via multiple support rods. The sides of the cable trays are connected to the bottom support via connecting plates. A sliding connecting groove is positioned above the connecting plates. A top support is connected to the bottom support via the sliding connecting groove. The top support matches the internal shape of the protective pipeline. A connecting platform is positioned at the lower center of the top support. The connecting platform is connected to a limiting frame via screws. The bottom sides of the limiting frame are connected to the sliding connecting groove. The multiple cable trays are interconnected via multiple connecting rods, and a support frame is positioned in the middle of the multiple connecting rods.

[0004] However, the above-mentioned device still has some drawbacks in actual use.

Then, multiple protective pipes 1 are spliced ​​and assembled, and the municipal pipeline passes through the inside of the protective pipe 1. At the same time, the municipal pipeline is erected above the clamping member a7. Subsequently, the top bracket 4 and the bottom bracket 3 can be fixed with the locking bolt 9, and the threaded sleeve 10 is rotated. Through the rotation of the threaded sleeve 10, the threaded rod 11 can continuously extend out from the inside of the threaded sleeve 10. Under the action of the limiting component, the clamping member b8 can move up and down. With the cooperation of the clamping bar 17 and the clamping groove 18, the clamping member b8 and the clamping member a7 can achieve the purpose of clamping and fixing pipes of different sizes.
