Cast-in-situ bored pile collapse hole treatment device and method
The invention discloses a cast-in-situ bored pile hole collapse disposal device and method.The cast-in-situ bored pile hole collapse disposal device comprises a first drill rod and a plurality of second drill rods which are sequentially connected from bottom to top, the first drill rod and each second drill rod are hollow pipes with the two ends communicated, and the outer side wall of the lower end of the first drill rod is connected with a hob head; the hob head is connected with a plurality of hob heads; a plurality of tough brush strips are evenly distributed and connected to the outer side wall of the first drill rod in the circumferential direction and the height direction of the first drill rod. During hole collapse treatment, the pile forming quality can be guaranteed, it can also be guaranteed that the reinforcement cage is not damaged, meanwhile, the process of repeatedly installing and lowering the reinforcement cage is reduced, and the construction efficiency is improved.
本发明公开了一种钻孔灌注桩塌孔处置装置和方法，包括从下向上依次连接的第一钻杆和若干第二钻杆，所述第一钻杆和每个所述第二钻杆均为两端贯通的中空管，所述第一钻杆的下端外侧壁连接有滚刀架，所述滚刀架上连接有若干滚刀头；所述第一钻杆的外侧壁上沿自身周向和高度方向均布连接有若干韧性刷条。塌孔处置时，本发明既可保证成桩质量亦可保证钢筋笼不被破坏，同时减少了重复安装下放钢筋笼过程，提高了施工效率。
