Dredging method for preventing blow-off pipe from being blocked

Abstract

The invention discloses a dredging device for preventing a blow-off pipe from being blocked. The device comprises a pipe body, wherein clearing openings are formed in the surface of one side of the pipe body at equal intervals; a liquid storage flow guide assembly is arranged on the inner side of each clearing opening, an adjusting groove is formed in the bottom end of the liquid storage flow guide assembly, a rotating rod is fixedly installed on the inner side of the adjusting groove, a connecting block is rotatably installed on the outer side of the rotating rod, and a crushing assembly is arranged at the bottom end of the connecting block. According to the method, in the pipeline dredging process, the blockage position can be observed and positioned in real time first through an observation window, then the clearing opening at the corresponding blockage position is opened, a holding rod extends to the pipeline blockage position on the inner side of the clearing opening, and rapid clearing can be achieved by spraying a clearing agent; and a traditional mode that it is required to clear from the starting end of a pipeline to the tail end is replaced, a target to be cleared is clearer, the clearing procedure is simpler, the clearing workload is greatly reduced, and the overall clearing efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of pipe dredging, in particular to a dredging method for preventing sewage pipes from being blocked. Background technique [0002] Sewage pipes are an indispensable part of high-rise building construction. Its function is to discharge waste water and excrement in high-rise buildings to the outside. In daily life, the phenomenon of blockage of sewage pipes occurs from time to time, which brings great harm to people's daily life. A lot of inconvenience, when there are many serious blockages in the sewage pipeline, the staff need to dredge the sewage pipeline through dredging equipment. [0003] At present, the pipeline is dredged from the beginning to the end of the sewage pipeline, which greatly increases the workload of pipeline dredging and reduces the overall efficiency of pipeline dredging. At the same time, the existing dredging is mainly performed manually, which is very troublesome and time-consuming. ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a dredging method for preventing the blockage of the sewage pipe, so as to solve the problem that the current pipeline is dredged from the beginning to the end of the sewage pipe proposed in the above-mentioned background technology, which greatly increases the workload of the pipe dredging and reduces the cost of the pipeline. The overall efficiency of dredging, at the same time, the existing dredging is mainly performed manually, which is very troublesome, time-consuming and labor-intensive.
