Description

Technical Field

[0001] The present application relates to the field of foundation pit construction, and in particular to a deep foundation pit dewatering well structure applied to high-water-level silty soil. Background Art

[0002] At present, when excavating deep foundation pits in areas with high water levels, the water layer is cut off. Under the action of pressure difference, groundwater will continuously seep into the foundation pit. If the foundation pit drainage is not carried out, it will cause water seepage in the foundation pit, resulting in a decrease in the bearing capacity of the foundation. Therefore, when excavating deep foundation pits in areas with high water levels, groundwater drainage projects are usually carried out.

[0003] Because the precipitation well has been subjected to precipitation operations for a long time, a large amount of silt will be generated in the precipitation well. In order to avoid blockage inside the precipitation well, the silt is usually removed from the bottom of the precipitation well regularly.

[0004] The above-mentioned prior art solutions have the following defects: the existing well body sludge cleaning devices are generally used to clean the bottom of the well, but have no effective cleaning effect on the well wall. Utility Model Content

[0008] By adopting the above scheme, a cleaning device is arranged in the well body, and the cleaning device is used to clean the silt on the side wall of the well body. The cleaning device includes a rotating rod and a cleaning rod. The rotating rod is arranged at the center of the well body and is rotatably connected to the well body. The cleaning rod and the rotating rod are fixedly connected by a positioning piece, so that the rotation of the rotating rod can drive the cleaning rod fixedly connected to the rotating rod to rotate along the inner wall of the well body.
