Problems solved by technology

However, because the device uses a corrugated pump to discharge sewage, it is difficult to manufacture, and the corrugated pump and the sewage inlet and outlet are designed in the center of the pipeline. During the test, it was found that it is not conducive to sucking the sludge into the corrugated pump.

Abstract

The invention provides a desilting device used for an underdrainage pipeline and a stepped type moving method of the desilting device. The desilting device comprises a front installation disc and a rear installation disc which are arranged in the advancing direction of the desilting device; a propelling cylinder is arranged between the front installation disc and the rear installation disc and used for changing the relative distance between the front installation disc and the rear installation disc; the front installation disc and the rear installation disc are in contact with the inner wall of a drainage pipeline through support units; through the movement cooperation between the support units and the propelling cylinder, the desilting device is moved forward or backward; a silt discharging cylinder is arranged at the position, between the front installation disc and the rear installation disc, of the bottom side and used for delivering silt generated in the desilting process. By means of the desilting device, the silt is discharged thoroughly, the operation is simple and reliable, and the silt discharging efficiency is obviously improved.

Description

technical field [0001] The invention relates to the field of cleaning municipal underground drainage pipes, in particular to a dredging device for underground drainage pipes and a step-type moving method thereof. Background technique [0002] The urban underground drainage system used to prevent urban waterlogging and drainage is one of the important infrastructures of the city. Usually, the diameter of the branch line of the drainage system is only 600-800mm. In the case that the drainage pipe produces silt due to long-term operation, the dredging work for the pipeline cannot be completed by manual entry. [0003] The existing device for reclaiming the sedimented sludge in the drainage pipe is to hold the suction hose nozzle by the staff, and the suction hose nozzle is connected with the recovery tank equipped with an air suction pump on the ground, and the suction hose nozzle is extended Into the drainage pipe, the settled sludge is recovered to the recovery tank on the g...
