Rigid-flexible combined underground diaphragm wall anti-seepage joint and construction method thereof
The invention discloses a rigid-flexible combined underground diaphragm wall anti-seepage connector which comprises two trapezoid modules and a plurality of expansion water stop strips, the two trapezoid modules are of trapezoid structures, the expansion water stop strips are installed at the two ends of the two trapezoid modules respectively, the narrow bottom ends of the two trapezoid modules are connected to form a symmetrical V-shaped concave surface structure, and the narrow bottom ends of the two trapezoid modules are connected to form a U-shaped concave surface structure. And one V-shaped concave surface structure is connected with the pre-pouring section, and the other V-shaped concave surface structure is connected with the post-pouring section. According to the method, the action of water and soil pressure of the outer wall of the underground diaphragm wall is reasonably utilized, passive water and soil pressure is converted into active pressure, a gap between the joint and the wall body is compacted, and therefore the problem that water stop at the joint loses efficacy due to overlarge external pressure is solved; the trapezoidal modules are arranged in a symmetrical structure, even if the underground water level of the outer wall descends, the connector cannot slide towards the outer wall, the stability of the connector of the continuous wall is practically guaranteed, and the best anti-seepage effect is achieved.
本发明公开了一种刚柔组合的地下连续墙防渗漏接头，包括两个梯形模块和多个膨胀止水条，两个所述梯形模块为梯形结构，多个所述膨胀止水条分别安装于两个梯形模块的两端，两个所述梯形模块的窄底端连接形成对称的V字凹面结构，一个所述V字凹面结构与先浇段连接，另一个所述V字凹面结构与后浇段连接。本发明合理利用地下连续墙外墙的水、土压力的作用，转化被动的水、土压力为主动压力，压紧密实接头于墙体之间的缝隙，从而解决过大的外界压力导致接头处止水失效的难题；梯形模块做成了对称结构对称的结构布置，即使在外墙的地下水位下降时，依然不会使接头向外墙滑移，切实保证了连续墙接头的稳定性，发挥最佳的防渗漏效果。
