Problems solved by technology

Due to the sediment and impurities in the sewage, siltation will occur in the wall of the drainage pipe after long-term use, especially the wall of the drainage pipe located downstream. If it is not maintained in time, the drainage capacity of the municipal drainage pipe will be affected
[0003] At present, there are mainly three methods of desilting in the market: manual, mechanical equipment and robots, but there are problems such as heavy workload, complex equipment structure that cannot be applied to all drainage pipelines, and high cost of desilting.

Abstract

The invention discloses a drainage pipeline water conservancy automatic desilting method based on high-pressure jetting, high-pressure water is introduced into the pipe wall of a drainage pipeline, and the high-pressure water is jetted into an inner cavity of the drainage pipeline from the pipe wall of the drainage pipeline. The improved municipal drainage pipeline in the water conservancy dredging method has the advantage of automatic dredging.

Description

technical field [0001] The invention belongs to the technical field of dredging of municipal drainage pipes. More specifically, the present invention relates to a water conservancy automatic dredging method for drainage pipelines based on high-pressure jetting. Background technique [0002] Municipal drainage pipes refer to rainwater and sewage pipes under municipal roads, which are important infrastructures of cities. Due to the sediment and impurities in the sewage, siltation will occur in the wall of the drainage pipe after long-term use, especially the pipe wall located downstream of the drainage pipe. If it is not maintained in time, the drainage capacity of the municipal drainage pipe will be affected. [0003] At present, dredging is mainly done by manual, mechanical equipment and robots in the market, but there are problems such as heavy workload, complex equipment structure that cannot be applied to all drainage pipelines, and high cost of dredging.
