Construction method of prefabricated underground diaphragm wall
The invention discloses a construction method of a prefabricated underground diaphragm wall. The construction method comprises the steps that underground diaphragm wall body units are prefabricated; an underground diaphragm wall groove is excavated; rubber capsule bodies are pasted in a second groove and a third groove of each wall body unit; second steel parts and first steel parts are installed in gaps and fourth grooves in the wall units; a first wall body unit is put into the groove; a second wall body unit is inserted along the first groove of each wall body unit, so that a tenon of the second wall body unit is embedded into the first groove of the first wall body unit, and the second steel parts and the first steel parts are mutually tied; the subsequent wall body units are continuously inserted in the groove direction of the underground diaphragm wall, and liquid grouting bodies are injected into the bag bodies at the joints of the first wall body unit and the second wall body unit; cement-based grout is injected into a steel floral tube of the second steel part; after the multiple wall units are constructed, cement slurry is poured into gaps between the wall units and the grooves, and slurry in the gaps is replaced; and the steps are carried out until construction of the underground diaphragm wall is completed. According to the construction method, the construction speed is high, and the waterproof effect is good.
本发明公开了一种预制装配式地下连续墙的施工方法：预制地下连续墙墙体单元；开挖地下连续墙沟槽；在每个墙体单元的第二、三凹槽内粘贴橡胶囊体；在墙体单元上的缝隙和第四凹槽内安装第二、第一钢件；向沟槽内放入第一墙体单元；沿墙体单元的第一凹槽插入第二墙体单元，使第二墙体单元的凸榫嵌入第一墙体单元的第一凹槽中，并使第二钢件和第1钢件相互拉结；沿地下连续墙沟槽方向连续插入后续墙体单元，在第一、二墙体单元接缝处的囊体内注入液态注浆体；向第二钢件的钢花管内注入水泥基浆液；施工多个墙体单元后，在墙体单元与沟槽间的缝隙内灌注水泥浆浆液，置换间隙处的泥浆；按上述步骤直至地下连续墙施工完成。其施工速度快、防水效果好。
