Pile foundation hole collapse treatment method
The invention discloses a pile foundation hole collapse treatment method. The pile foundation hole collapse treatment method comprises the steps that a rotary drilling rig is adopted to dig to a holecollapse part, silt generated by hole collapse is removed, concrete is adopted for recharging, recharging is carried out to the hole collapse top, after the concrete is solidified, a middle part of the solidified concrete is taken out, and the rest parts form a concrete retaining wall to prevent intensifying of hole collapse. According to the treatment method, the concrete is adopted for recharging to form a hole, the hole collapse problem can be effectively solved according to a project situation, and the construction period requirement is met.
本发明公开了一种桩基塌孔处理方法，所述桩基塌孔处理方法包括：先采用旋挖钻机挖至塌孔部位，清除已塌孔的泥沙，并采用混凝土回灌，回灌至塌孔顶部，待混凝土凝固后，掏出凝固混凝土中间部分，剩余部分将形成混凝土护壁阻止塌孔的加剧。本处理方法通过采用混泥土回灌成孔，能够针对项目情况，有效解决塌孔问题，满足工期需求。
