Construction method for reducing concrete consumption of special-shaped underground diaphragm wall
The invention belongs to the technical field of underground diaphragm walls, discloses a construction method for reducing the concrete consumption of a special-shaped underground diaphragm wall, and provides the construction method for reducing the concrete consumption of the special-shaped underground diaphragm wall in order to solve the problem that pouring concrete is wasted due to arrangement of an external groove. The method comprises the following steps: (1) constructing a groove body and an external groove; (2) a wall reinforcement cage is manufactured, a steel cushion block is installed on the wall reinforcement cage, a steel plate is clamped in a clamping groove of the steel cushion block, a baffle is arranged on the steel plate in a matched mode, and the baffle is used for a grout stop belt making contact with the wall of the external groove; (3) hoisting a wall reinforcement cage into the groove body; (4) grouting floral tubes and sandbags are implanted into the outward placing grooves; (5) grout is injected into the outward discharging groove through the grouting floral tube, and then the steel plate is taken out of the steel cushion block; and (6) concrete is poured into the groove body to form the underground diaphragm wall. The problem of concrete waste caused by the external groove can be effectively reduced, and the construction cost of the special-shaped underground diaphragm wall is reduced.
本发明属于地下连续墙技术领域，公开了一种降低异形地下连续墙混凝土用量的施工方法，为了解决由于外放槽的设置导致浇筑混凝土浪费的问题，而提供一种降低异形地下连续墙混凝土用量的施工方法。本发明包括：(1)施工槽体和外放槽；(2)制作墙体钢筋笼，所述墙体钢筋笼上安装有钢垫块，钢垫块的夹持槽内夹持有钢板，钢板上配设有挡板，挡板用于与外放槽墙壁接触的止浆带；(3)将墙体钢筋笼吊装入槽体中；(4)向外放槽中植入注浆花管和放入沙袋；(5)通过注浆花管向外放槽中注入浆液，然后钢垫块上取出钢板；(6)向槽体中浇筑混凝土形成地下连续墙。本发明能够有效的减少外放槽带来的混凝土浪费的问题，降低异形地下连续墙的施工成本。
