Description

Technical Field

[0001] This utility model relates to the field of pipeline installation protection technology, and more specifically, to a pipeline protection device for municipal water supply. Background Technology

[0002] In municipal water supply pipelines, longer pipes need to be supported in the middle. The connection between two pipe sections is prone to breakage. Furthermore, after the pipeline is buried, it is usually necessary to prevent it from being dug up during excavation work in the vicinity. Therefore, pipeline protection is usually required.

[0003] Patent CN214789405U discloses a protective structure for municipal pipelines. After excavating a trench, spacers are placed inside, and the pipeline is installed on the spacers. Limiting blocks are then fixed to the spacers, and the pipeline is positioned in the trench. Support blocks are then installed sequentially above the pipeline, inserted into the trench. Steel wire ropes and fixing ropes are attached to the limiting blocks, and the steel wire ropes are fixed to the support blocks. This allows the steel wire ropes to effectively withstand downward pressure, reducing the likelihood of damage to the pipeline due to external factors when it is buried underground. However, this municipal pipeline protective structure only prevents damage from above; it is ineffective in preventing damage from the sides. Furthermore, the number of supporting structures below the pipeline is insufficient to provide adequate support. Utility Model Content
