Joint connection and construction method of prefabricated underground diaphragm wall and cast-in-place composite wall
The invention discloses a node connection and construction method of a prefabricated underground continuous wall and a cast-in-place composite wall, and the node connection comprises a prefabricated underground continuous wall, the prefabricated underground continuous wall is fixedly connected with a cast-in-place underground continuous wall, and a cast-in-place buttress is poured on the inner side of the joint of the prefabricated underground continuous wall and the cast-in-place underground continuous wall. A cast-in-place structure side wall is cast on the inner side of the cast-in-place underground diaphragm wall and the side wall of the cast-in-place buttress; the construction method comprises the following steps: processing the prefabricated diaphragm wall; a cast-in-place diaphragm wall reinforcement cage is bound, and welding angle steel is installed; underground diaphragm wall grooving construction is carried out; scabbling the surface of the joint of the prefabricated diaphragm wall, and pasting a water-swelling water stop strip; the prefabricated diaphragm wall and the cast-in-place diaphragm wall reinforcement cage are hoisted, and concrete is poured; grouting is conducted on vertical seams between the widths; building envelope construction is completed, and angle steel welding construction is conducted along with foundation pit excavation; and cast-in-place structural side walls and cast-in-place buttresses are cast and constructed. The construction efficiency is improved, the construction site is reduced, and the manufacturing cost is saved.
本发明公开了一种预制地下连续墙与现浇复合墙的节点连接及施工方法，其节点连接包括预制地下连续墙，预制地下连续墙与现浇地下连续墙固定连接，预制地下连续墙、现浇地下连续墙连接处内侧浇筑有现浇扶壁柱，现浇地下连续墙内侧、现浇扶壁柱侧壁处浇筑有现浇结构侧墙；其施工方法，包括以下步骤：加工预制地连墙；绑扎现浇地连墙钢筋笼并安装焊接角钢；地连墙成槽施工；进行预制地连墙连接处表面凿毛处理，粘贴遇水膨胀止水条；吊装预制地连墙和现浇地连墙钢筋笼，浇筑混凝土；进行幅间的竖缝注浆；完成围护结构施工，随基坑开挖进行焊接角钢焊接施工；浇筑施工现浇结构侧墙、现浇扶壁柱。本发明提高了施工效率、缩减建设场地，节省造价和成本。
