[0001] The invention relates to the technical field of building pile holes, and in particular to a device for cleaning the inside of a building pile hole. Background Art

[0002] In the field of construction engineering technology, a pile hole is a cylindrical hole extending into the ground. Concrete is poured into the pile hole to form a pile head, which can make the building more solid. On complex and harsh construction sites, soil is often washed into the pile hole by construction site water or rainwater, which affects the normal pouring in the pile hole. The soil in the pile hole must be cleaned out, otherwise the quality of the pile head cannot be guaranteed.

[0003] At present, most of the existing pile hole cleaning devices extend into the pile hole through an auger, and the auger rotates to bring out the soil in the pile hole, but the soil brought out by the auger will accumulate at the edge of the pile hole port and easily fall back into the pile hole, and the auger cannot clean the adhered soil blocks, convex soil blocks, loose soil blocks, etc. on the inner wall of the pile hole. Over time, the soil blocks on the inner wall of the pile hole will still fall into the pile hole, and the auger is cumbersome to disassemble and assemble. Summary of the invention
