AI Technical Summary
Existing borehole cleaning devices for cast-in-place piles are prone to colliding with the borehole wall during the cleaning process, resulting in damage and contamination of the borehole wall and affecting the construction quality.
The height and level are adjusted by foot support components, combined with elastic rolling contact components, and the lifting cylinder makes elastic rolling contact with the inner wall of the pile hole to avoid direct contact damage. The slurry is cleaned by spiral feeding knife.
This effectively avoids damage to the inner wall of the pile hole, improving cleaning efficiency and construction quality.
