Description

Technical Field

[0001] The utility model relates to the technical field of desilting wells, in particular to a desilting device for a subway deep foundation pit desilting well. Background Art

[0002] As we all know, a subway deep foundation pit refers to an engineering project with an excavation depth of more than 5 meters (including 5 meters), or a project with a depth of less than 5 meters but with particularly complex geological conditions, surrounding environment and underground pipelines. Foundation pit engineering is very regional and also different in different cities and regions. It must be carried out according to local actual conditions. Therefore, there are various diameters of deep foundation pit dewatering wells.

[0003] Chinese utility model disclosure specification CN221255597U discloses a silt clearing device for a subway deep foundation pit dewatering well, which includes a wall cleaning mechanism, a water washing mechanism and a bottom cleaning mechanism. The wall cleaning mechanism is located outside the bottom cleaning mechanism, and the water washing mechanism is located above the bottom cleaning mechanism. The wall cleaning mechanism includes a support rod and a vertical scraper. The support rod is fixedly installed at the outer end of the bottom cleaning mechanism. The support rods are symmetrically distributed, and the vertical scraper is fixedly installed at the outer end of the support rod.

[0004] Although the device has the characteristic of improving the dredging effect, the vertical scraper of the device is fixedly installed on the conveying drum through the support rod, and the annular scraper is fixedly set on the conveying drum. It is not convenient to adjust the diameters of the annular scraper and the vertical scraper according to the diameter of the foundation pit dewatering well. Therefore, it can only dredge the foundation pit dewatering wells of the same diameter. Secondly, since it is fixed, when the annular scraper or the vertical scraper is worn to a certain extent and needs to be repaired or replaced, it is not convenient to remove the two from the subway deep foundation pit dewatering well dredging device. Therefore, the practicality is not very good and there is room for improvement. Utility Model Content
