[0002] At present, in the construction process of new energy photovoltaic power stations, micro-hole cast-in-place piles with small apertures (150 mm-200 mm) are mostly used, and the holes are formed by using an air compressor and a drilling machine or by artificial mechanical hole forming. In the hole forming construction process, the hole wall and part of the ground may fall back into the hole, or in the case of uneven geological conditions, the hole may collapse, resulting in that the hole depth does not meet the design requirements, the thickness of the hole wall concrete protection layer does not meet the design requirements, and the hole bottom steel directly contacts the soil, which may cause the micro-hole cast-in-place pile to rust, and further affect the pile foundation bearing capacity and cause safety and quality risks. Based on the above reasons, secondary sedimentation hole cleaning is required before concrete pouring, and the sedimentation hole cleaning is generally performed by artificial hole digging and sediment removal. New energy photovoltaic power stations are increasingly widely used, and there are high requirements for structural safety and construction convenience. Therefore, there is an urgent need to provide a new scheme for micro-hole pile hole sediment cleaning to reduce construction quality and safety risks. At present, the existing sediment hole cleaning methods have the following shortcomings:
[0003] 1) The construction environment of the photovoltaic area is complex, and in the process of using a soil digging shovel to dig a hole, the soil digging shovel will exert force on the hole wall, which is easy to cause safety accidents or secondary sedimentation.
[0004] 2) The soil digging shovel is used to remove the sediment in the hole, and the soil digging shovel needs to be inclined at a certain angle to remove the sediment, but due to the limitation of the hole wall, the inclination angle of the soil digging shovel is limited, which leads to incomplete hole cleaning and large disturbance, and further causes the hole diameter to become larger and the concrete material to be wasted. SUMMARY
