Method for treating remaining pile foundations within range of underground diaphragm wall
The invention discloses a method for treating remaining pile foundations within the range of an underground diaphragm wall. The underground diaphragm wall, the pile foundations, the pile foundation outer wall, a reinforcing steel bar group, a fitting groove, a grooving machine, a multi-excavation part, a backfill area and a jet grouting pile are included. The method comprises the following construction steps that a guide wall groove is excavated and pouring construction is carried out to finish the construction of the underground diaphragm guide wall; underground diaphragm wall grooving construction is carried out; and during construction, all the remaining pile foundations within the range of the underground diaphragm wall are pulled out through a trenching machine. In the grooving process, the remaining pile foundations are pulled out, so that a groove section of the whole diaphragm wall is changed into an L shape, before a reinforcement cage of the diaphragm wall is hoisted, a wood formwork is installed at the corresponding position (multiple grooving positions) of the reinforcement cage, then the reinforcement cage is hoisted, the outer side (the outer side of the wood formwork) of the diaphragm wall is filled with sand bags, so that a small number of small-diameter remaining pile foundations in the range of the underground diaphragm wall can be simply and rapidly treated, and the tedious process and investment during pile pulling construction are reduced.
本发明公开了一种处理地连墙范围内遗留桩基的方法,包括:地连墙、桩基、桩基外壁、加强钢筋组、贴合槽、成槽机、多开挖部分、回填区和旋喷桩,施工步骤如下:开挖导墙槽并进行浇筑施工,完成地连导墙的施工;地连墙成槽施工;施工时用成槽机将全部在地连墙范围内的遗留桩基拔出。在成槽过程中将遗留桩基拔出,使得整个地连墙的槽段变成L形,在地连墙钢筋笼吊装前,在钢筋笼的相应位置(多成槽位置)安装木模板,然后吊装钢筋笼,通过在地连墙外侧(木模板外侧)填充砂袋,从而可以简单、快速的处理地连墙范围内遗留的少量小直径桩基,减少拔桩施工时的繁琐流程及投入。
