Embodiment Construction

[0024] With the continuous improvement of people's living standards and the continuous improvement of living supporting equipment, the requirements and cognition of engineering quality are also gradually improving. The present invention should also adopt reasonable and efficient methods for the treatment of sedimentation wells in sewage inspection wells. Cleaning, replace the traditional process with recyclable equipment, improve the effect of sludge cleaning, prevent pipeline congestion, completely replace manual operations with mechanical equipment, reduce the frequency of manual downholes, ensure a safe working environment for workers, and reduce maintenance costs and sewage blockages problem occurs.

[0025] Such as Figure 1-3 As shown, a desilting device for a municipal drainage engineering desilting well: it includes a conical filter 2 arranged at the wellhead, and the mesh 101 of the conical filter 2 is a detachable structure; the lower part of the conical filter 2 is ...

Abstract

The invention provides a municipal drainage engineering catch-basin dredging device. The municipal drainage engineering catch-basin dredging device comprises a tapered filter screen arranged at a wellhead position, and meshes of the tapered filter screen are of detachable structures; a sewer pipe is mounted on the lower part of the tapered filter screen, and the sewer pipe extends into a downstream pipeline along the well wall; a circulating water suction pump is mounted in a catch basin, a shaft suction pipe is mounted on the left side of the water suction pump, and a water supply pipe is mounted on the right side of the water suction pump; the bottom end of the shaft suction pipe is arranged at a well bottom position; the water supply pipe extends upwards along the well wall and a top pipe opening is formed in the filter screen meshes; and stirring paddles are further arranged at the bottom of circulating water suction pump, and helical blades of the stirring paddles are explored into sludge residues of the well bottom after sedimentation. The invention further provides a dredging method adopting the municipal drainage engineering catch-basin dredging device. The dredging methodadopting the municipal drainage engineering catch-basin dredging device comprises the steps that the circulating water suction pump is started for operating, so that sludge is sucked into the water supply pipe from the suction pipe to the tapered filter screen for filtration, and finally, water is recycled into the catch basin from the sewer pipe. The filter screen is replaced when certain sludgeis accumulated, the matching equipment can be reused circularly, the cleaning and pulling effect is good, and the speed is high.

Description

technical field [0001] The invention belongs to a municipal mud well drainage project, and in particular relates to a device and a dredging method for periodically dredging a sediment inspection well. Background technique [0002] The function of the sewage sedimentation well is to collect the solid sediment in the pipeline to prevent partial congestion of the pipeline and cause the entire pipeline to be blocked. [0003] Cleaning of sedimentation wells in the prior art: ①When the depth of sedimentation wells is shallow and the amount of sludge reaches the reserved thickness, sewage suction trucks will be used for sewage suction treatment. The existing treatment method of sewage suction trucks is in the form of cans To collect sewage and silt, extend the sewage suction pipe into the bottom of the inspection well to absorb sewage. During the cleaning operation of the sewage suction truck, the bottom of the inspection well is in an invisible environment, which is difficult to ...
