The invention relates to a high-stability foundation construction method which comprises a column hammer used for foundation treatment, the column hammer comprises a hammer sleeve and an inner pipe, the hammer sleeve is provided with a filling groove, the filling groove is located at the top of the hammer sleeve, the inner pipe slides in the filling groove, the sliding direction of the inner pipe is the extending direction of the filling groove, the inner pipe is provided with a limiting ring groove, and the limiting ring groove is located in the filling groove. The limiting ring groove is located in the side, away from the filling groove, of the inner pipe, the groove wall of the limiting ring groove is provided with a rotating plate, the rotating plate rotates on the groove wall of the limiting ring groove, the groove wall of the filling groove is provided with a communicating hole, the communicating hole penetrates through the hammer sleeve to the limiting ring groove, and when the rotating plate abuts against the side, close to the filling groove, of the groove wall of the limiting ring groove, the connecting hole is communicated with the limiting ring groove. And the rotating plate closes the communicating hole. The contact area of the whole column hammer and the foundation is increased, and therefore the follow-up sinking condition of the column hammer is reduced.
本申请涉及一种高稳定性地基的施工方法，其包括用于地基处理的柱锤，所述柱锤包括锤套与内管，所述锤套设有填充槽，所述填充槽位于锤套顶部，所述内管滑移于填充槽，所述内管的滑移方向为填充槽的延伸方向，所述内管设有限位环槽，所述限位环槽位于内管背离填充槽的一侧，所述限位环槽槽壁设有转动板，所述转动板转动于限位环槽槽壁，所述填充槽槽壁设有连通孔，所述连通孔贯通锤套至限位环槽，当所述转动板抵触限位环槽槽壁靠近填充槽的一侧时，所述转动板闭合连通孔。本申请提升了柱锤整体于地基的接触面积，从而减少了柱锤后续下沉的情况。
