Construction method aiming at filling of first-stage groove section joint of underground diaphragm wall
The invention discloses a construction method aiming at filling of a first-stage groove section joint of an underground diaphragm wall. The construction method comprises the steps that after a first-stage groove segment steel reinforcement cage of the underground diaphragm wall is welded, and two steel bar hooks are welded at the lower part of an H-shaped steel; after the steel reinforcement cageis hoisted to the determined hole position, an anti-puncture water bag is fixed to the bottom of the steel reinforcement cage, the steel reinforcement cage is placed, and the anti-puncture water bag is lowered along with the reinforcement cage, the water bag is filled with water, so that the backfill compactness is guaranteed; after it is determined that the underground diaphragm wall is not offset and inclined, the underground diaphragm wall is poured; the anti-puncture water bag and the H-shaped steel are peeled off by using an auxiliary wall brushing device when the adjacent second-stage groove section is excavated, and then the rear brush wall is cleaned up, and it is guaranteed that the seam does not intercalated mud and the broken bag. According to the construction method, a traditional bagged macadam filling is replaced, no displacement of the steel reinforcement cage during pouring is guaranteed, and the construction compactness and stability are guaranteed.
本发明公开了一种针对地下连续墙一期槽段接头填充的施工方法，包括地下连续墙一期槽段钢筋笼焊接完成后，在H型钢下部焊接两个钢筋弯钩；吊装钢筋笼到确定孔位后将防刺穿水袋固定在钢筋笼底部；安放钢筋笼，并随钢筋笼下放将防刺穿水袋延钢筋笼下放；将水袋灌满水，保证回填的密实性，在确定地下连续墙未偏移、倾斜后，浇筑地下连续墙；临近的二期槽段开挖时使用辅助刷壁器将防刺穿水袋和H型钢剥离，然后清除干净后刷壁，保证接缝无夹泥、碎袋。本方法代替传统的袋装碎石填充，保证浇筑时钢筋笼不发生位移，保证了施工密实性与稳定性。
