Method for removing cast-in-place pile
The invention discloses a cast-in-place pile removing method. The cast-in-place pile removing method comprises the steps that a positioning assembly is arranged on the surface of a stratum where a cast-in-place pile is located; wherein a positioning hole is formed in the positioning assembly, the hole diameter of the positioning hole is larger than the pile diameter of the cast-in-place pile, and the positioning hole is annularly formed in the outer side of the cast-in-place pile; a sleeve assembly penetrates through the positioning hole to be downwards placed in the stratum and is arranged on the outer side of the cast-in-place pile in a sleeving mode; the inner pipe diameter of the sleeve assembly is larger than the pile diameter of the cast-in-place pile. A geologic body between the sleeve assembly and the cast-in-place pile is dug out; putting a breaking hammer into the sleeve assembly and breaking the cast-in-place pile; the broken cast-in-place pile is dug out of the sleeve assembly; a geologic body is backfilled into the sleeve assembly; and upwards pulling the sleeve assembly out of the stratum. The cast-in-place pile is crushed into the fragments, then the fragments are dug out, the whole cast-in-place pile does not need to be hoisted out, and the method is simple, convenient and safe.
本发明公开了一种灌注桩的移除方法，包括所述灌注桩的移除方法包括：在所述灌注桩所在的地层的表面设置一定位组件；其中，所述定位组件形成有定位孔，所述定位孔的孔径大于所述灌注桩的桩径，所述定位孔环设于所述灌注桩的外侧；将套管组件穿过所述定位孔向下放置于所述地层中并套设于所述灌注桩的外侧；其中，所述套管组件的内管径大于所述灌注桩的桩径；将所述套管组件和所述灌注桩之间的地质体挖出；将破碎锤放入所述套管组件内并将所述灌注桩破碎；将破碎后的灌注桩从所述套管组件内挖出；向所述套管组件内回填地质体；将所述套管组件向上拔出所述地层。本发明通过将灌注桩破碎为碎块，再将碎块挖出，无需将整根灌注桩吊出，简单方便且安全。
