Description

System and method for dredging in large-diameter pipeline

Technical Field

The invention relates to the technical field of pipeline dredging, in particular to a system and a method for dredging in a large-diameter pipeline.

Background

In order to ensure the smoothness of the pipeline, the pipeline needs to be dredged regularly, especially for the pipeline in municipal administration pipelines and water conservancy, because the impurity carried in the conveying process is more, the pipeline is easy to deposit in the pipeline to cause blockage. For dredging of the pipe, the deposited impurities are loosened by disturbance and carried away by the water flow.

For short distance or pipeline with cellar well, the dredging can be disturbed by high pressure water gun, the principle is that high pressure water flow is sprayed by high pressure spray head, and the high pressure water flow impacts the sediment in the pipeline, so as to achieve the purpose of scouring and dredging. However, in the dredging method, because the jet distance of the high-pressure nozzle is limited, the dredging operation of the whole pipeline can be completed by pushing the stamping nozzle into the pipeline in the dredging process, and the sewage suction truck is required to intensively suck to complete the whole dredging operation after the completion of the dredging operation. Generally, the suction is carried out at the cellar well in the suction process of the sewage suction truck, and in order to improve the suction effect, the suction pipe needs to be manually driven to rotate so as to disturb sediments.
