Underground diaphragm wall adopting embedded steel structure connecting device and construction method
The invention discloses an underground diaphragm wall adopting a pre-embedded steel structure connecting device and a construction method, the underground diaphragm wall structurally comprises a single prefabricated wall body and a cast-in-place concrete structure, and the prefabricated wall body comprises a top section prefabricated wall body unit, a middle section prefabricated wall body unit, a bottom section prefabricated wall body unit and the pre-embedded steel structure connecting device. Through cavities are formed in the prefabricated wall body units in the vertical direction, up-down through anti-seepage cavities are formed after assembly, reinforcement cages are placed in the anti-seepage cavities, concrete is poured into the anti-seepage cavities to form columnar cast-in-place reinforced concrete structures, and the single prefabricated assembled wall body forms a solid structure and is finally connected into a whole. The problems that a prefabricated underground diaphragm wall is large in dead weight and difficult to construct are solved, and the assembling construction efficiency and quality of the prefabricated underground diaphragm wall are improved; the defects of insufficient rigidity and weak bending resistance of horizontal connecting parts between prefabricated underground diaphragm wall units are overcome, and the problems of weak performance and easy leakage of vertical connecting parts between traditional underground diaphragm walls are solved.
本发明公开了一种采用预埋钢结构连接装置的地下连续墙及施工方法，结构包括单幅预制装配墙体及现浇混凝土结构，预制墙体包括顶节段预制墙体单元、中间段预制墙体单元、底节段预制墙体单元和预埋钢结构连接装置。预制墙体单元沿竖直方向设置贯通空腔，装配后形成上下贯通防渗空腔，防渗空腔内放入钢筋笼并灌注混凝土形成柱状现浇钢筋混凝土结构，使单幅预制拼装墙体形成实心结构，并最终连成整体。本发明解决了预制地下连续墙自重大、施工困难的问题，提高了预制地下连续墙装配施工效率和质量；解决了预制地下连续墙单元之间水平向连接部位刚度不足，抗弯性能弱的不足，克服了传统各幅地下连续墙之间竖直向连接部位性能弱，易渗漏的问题。
