Rigid joint diaphragm wall and construction method thereof
The invention discloses a rigid joint diaphragm wall and a construction method thereof, a first-stage groove section of the novel extension socket type rigid joint diaphragm wall is of a steel shell concrete structure, and the overall rigidity and stress performance of the diaphragm wall can be improved; the joint area is provided with the lap joint reinforcing mesh, no rib-free area exists, and the stress performance is high; the perpendicularity is monitored in real time in the steel box lowering process, the mounting posture of the steel box is adjusted through a position adjusting system after the steel box is lowered, and high-precision mounting of the steel box is achieved; a composite anti-streaming system composed of anti-streaming iron sheets, gravels, water bags and connector boxes is adopted, and the concrete streaming risk is reduced; the wall side and wall bottom soil bodies are reinforced through wall bottom and wall side mud jacking, the influence of wall side mud cakes and a wall bottom sediment layer on the bearing performance of the underground diaphragm wall is eliminated, and the bearing performance of the steel box connector underground diaphragm wall is improved; the construction quality can be effectively improved, and the construction speed is increased.
本发明公开了一种刚性接头地连墙及其施工方法，新型排插式刚性接头地连墙一期槽段为钢壳混凝土结构，可以提高地连墙的整体刚度与受力性能；接头区域存在搭接钢筋网片，不存在无筋区，受力性能较高；钢箱下放过程中对垂直度进行实时监测，钢箱下放完成后采用调位系统对钢箱安装姿态进行调整，实现了钢箱的高精度安装；采用由防绕流铁皮、碎石、水袋、接头箱组成的复合式防绕流系统，降低混凝土绕流风险；通过墙底及墙侧压浆对墙侧和墙底土体进行加固处理，消除墙侧泥皮以及墙底沉渣层对地连墙承载性能的影响，提高钢箱接头地连墙承载性能；其可有效提高施工质量，加快施工速度。
