Description

Technical Field

[0001] This patent relates to the technical field of aerial rope saws, specifically a rope saw for smooth cutting of concrete pipes. Background Art

[0002] Concrete drainage pipes are essential components of municipal drainage systems, primarily collecting and draining industrial water, rainwater, and sewage from factories and road surfaces. Improperly configured concrete drainage pipe connections can cause leakage, leading to sewage seepage through the pipe walls. In severe cases, this can cause the surrounding soil to collapse, compromising driving safety and potentially damaging the pavement structure. Therefore, proper drainage pipe connection placement is crucial to maintaining the stability of the roadbed, pavement, and surrounding soil, as well as ensuring driving safety.

[0003] During the use of existing concrete drainage pipes, a rope saw is required to excavate the concrete pipes. However, the traditional rope saw also needs to use a separate cooling pipe for cooling when working, which is less convenient. Therefore, the existing technology needs to be improved.
