Description

Technical Field

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

[0002] During the construction of deep foundation pits, in order to ensure the stability of the foundation pit and construction safety, it is usually necessary to set up precipitation wells to lower the groundwater level. However, as the construction progresses, a large amount of silt and other debris will accumulate in the precipitation wells, affecting their precipitation effect, so it is necessary to regularly desilt the precipitation wells.

[0003] The patent with announcement number CN219240673U discloses a high-water-level deep foundation pit desilting well desilting device, which is provided with a spiral blade. After the inner cavity of the mounting seat enters the bottom of the desilting well and immerses in the silt, the spiral blade is rotated under the operation of the driving motor. On the one hand, the rotation of the spiral blade stirs the silt to prevent the silt from being compacted by debris. On the other hand, the rotation of the spiral blade causes the silt to follow the spiral groove at the outer end of the spiral blade for transmission, and then the silt is collected by following the rise of the spiral groove until it reaches the top and falls into the annular cavity at the outer end for collection. The existing desilting device is usually designed to remove the silt and debris at the bottom of the desilting well, and may not be able to effectively clean the mud and debris adhering to the wall of the desilting well, resulting in poor desilting effect.

[0004] In view of this, it is urgent for those skilled in the art to design a dredging device to scrape away the mud and debris on the well wall and to perform directional cleaning of the well wall in order to achieve the best dredging effect. Utility Model Content
