[0002] The city underground space development and utilization process is rapid, and sinking well is widely used as a method of constructing underground space shaft. In some stratum rich in groundwater areas, non-drainage sinking well is usually used, that is, soil is taken with water in the well without lowering the groundwater. After the sinking well is sunk to the design elevation, underwater plain concrete is used to seal the bottom. After the bottom sealing layer concrete reaches the design strength, the water in the well is pumped out, and finally the structure in the shaft is constructed. The blade foot structure at the lowermost part of the sinking well and the bottom sealing layer form a circular contact surface. Before the underwater plain concrete is used to seal the bottom, mud, soil blocks and other sundries are inevitably attached to the blade foot wall surface, so that after the contact surface is formed, it is easy to form a channel for groundwater into the well, which seriously affects the normal construction in the shaft and the safety of the sinking well structure.

After the open caisson is excavated without draining and sunk to the design elevation, the mud in the shaft is first preliminarily purified by methods such as mud replacement and slag removal, so that the specific gravity of the mud in the shaft is reduced to meet the requirements before the bottom is sealed underwater. Then the cleaning device for the shaft wall surface and the blade foot of the utility model is assembled outside the shaft, at this time, the first support 2231 (straight surface) is installed to clean the vertical wall surface. After the device is assembled, the high-pressure water pump is connected with the pipeline 5, and the device is hoisted by the crane or other lifting equipment and hoisted into the shaft. When hoisted into the shaft, the rack 1 can be connected with the guide rail 4 on the shaft wall in sliding fit, and the rack 1 can be vertically lowered until the device reaches the preset elevation.

After the preparation work is completed, the rotation mechanism 12, the driver 21 and the high-pressure water pump are started. The two actuators 22 start to rotate 360° under the drive of the respective drivers 21, and at the same time, the cleaning mechanism 2 also rotates 360° around the main shaft 11 under the drive of the rotation mechanism 12. When the cleaning mechanism 2 rotates, the brush head 222 at the end of the rotating disc or the three rotating arms 221 brushes the vertical wall surface, so that the cleaning of the shaft wall of the open caisson can be realized. At the same time, the outlet of the high-pressure water pipeline 5 on the brush head 222 continuously sprays high-pressure water flow to flush the wall surface. Under the self-rotation and revolution of the cleaning mechanism 2, the vertical wall surface of the entire shaft wall circumference can be cleaned. After one cleaning cycle is completed, the device is lowered or lifted by the crane or other lifting equipment, and the cleaning of the wall surface at other heights is continued. After the vertical wall surface is cleaned from top to bottom, the device is hoisted out, the first support 2231 is replaced with the second support 2232 to clean the inclined surface of the blade foot, and after the replacement is completed, the same process is implemented to complete the cleaning of the inclined surface of the blade foot. After the entire cleaning work is completed, the sludge and soil blocks cleaned from the wall surface of the blade foot are treated by methods such as mud replacement and slag removal until the mud in the shaft meets the requirements before the bottom is sealed.
