Desilting and pollution discharge method for pipe culvert

Abstract

The invention discloses a desilting and pollution discharge method for a pipe culvert. The desilting and pollution discharge method includes the following steps that S1, according to the real-time information of a monitoring device in the pipe culvert, an inspection well into which a desilting device is to enter is selected; S2, silt extraction equipment is installed outside the inspection well, the pipe culvert desilting device is assembled and comprises a high-pressure water pump, a winch and a high-pressure hose, one end of the high-pressure hose communicate with a water outlet of the high-pressure water pump, the other end of the high-pressure hose communicates with a plurality of auxiliary spray heads and a main spray head, and the high-pressure hose is partially wound on the winch and can be driven to give off or take back by the winch; S3, the main spray head and all the auxiliary spray heads are placed in the pipe culvert, and meanwhile a silt extraction hose of the silt extraction equipment is put in the inspection well; S4, desilting is carried out through the pipe culvert desilting device; and S5, the silt extraction equipment is started to extract silt from the bottom of the inspection well. The obtained desilting and pollution discharge method for the pipe culvert can clean the inner wall of the pipe culvert in all directions and is convenient to operate.

Description

technical field [0001] The invention relates to a manual hole-digging pile, in particular to a pipe culvert dredging and sewage discharge method. Background technique [0002] In the existing municipal pipelines, after long-term use of many pipelines, a lot of silt will adhere to the pipe wall. In order to ensure the smoothness of the pipeline and prevent the clogging of the pipeline after long-term use, it is necessary to clean the pipe culvert regularly. At present, most pipes and culverts are dredged by high-pressure water flushing and other methods. When dredging, the dredging path of the pipeline is limited, and the flushing device is difficult to enter. [0003] In order to solve the above problems, there is an existing sewage pipe cleaning device, which includes a cleaning mechanism and a driving mechanism, and the cleaning mechanism includes a base and a spray head arranged on the base; The water spray pipe of the spray head, the driving mechanism drives the base t...

AI Technical Summary

Problems solved by technology

The cleaning device moves axially in the pipeline through the driving mechanism and sprays through the nozzle on the cleaning mechanism. The structure is complex and the cost is high. The driving mechanism walks in the water for a long time and is easily damaged after long-term use.

In addition, the nozzle of the above-mentioned cleaning device is at the top, so it can only wash the silt at the upper end of the pipeline, which is not comprehensive enough, and the silt after washing cannot be quickly concentrated and then extracted
