Cast-in-situ bored pile once hole cleaning device and hole cleaning method
The invention provides a cast-in-situ bored pile once hole cleaning device, which comprises a slag collecting barrel, a slag collecting barrel upper transverse frame, a square drill rod, a square drill rod upper baffle plate, a square drill rod lower baffle plate, a horizontal support rod, a first vertical support rod, a second vertical support rod, an inclined support rod, an inclined push rod, an umbrella-shaped slag collecting barrel cap top square hole, a square hole, a slag blocking plate, a chute, a horizontal push rod, a horizontal push rod guide ring, an external extending slag collecting mechanism tension spring, a slag collecting barrel lower transverse frame, a vertical plate, a short shaft, a bulge, a slag collecting barrel bottom plate, a slag collecting cutter plate, a connecting inclined plate and a rubber strip. The cast-in-situ bored pile once hole cleaning device has the advantages that the hole cleaning is completed after a steel reinforcement cage is placed, the defects of complicated construction and non-thorough hole cleaning of the existing once and twice hole cleaning method are overcome, the twice hole cleaning is changed into once hole cleaning, in addition, the hole cleaning can be thorough, sinking slag is not left, the quality of the pile body cannot be ensured, and the bearing force of the pile end can be fully exerted.
