Foundation pit basement outer wall construction joint anti-seepage structure and construction method thereof
The invention discloses a foundation pit basement outer wall construction joint anti-seepage structure and a construction method thereof. The foundation pit basement outer wall construction joint anti-seepage structure comprises a lower-layer outer wall, and a reverse ridge is formed on the inner edge of the top face of the lower-layer outer wall; the first grouting pipe is buried in the middle of the top face of the lower-layer outer wall and connected with a grouting guide pipe, and the grouting guide pipe extends to the outer portion of the inner side of the lower-layer outer wall; the two water-swelling waterstops are embedded in the top surface of the lower-layer outer wall, and the two water-swelling waterstops are arranged on the two opposite sides of the first grouting pipe correspondingly; the upper-layer outer wall is poured on the top surface of the lower-layer outer wall and the reverse ridge; the waterproof roll reinforcing layer is laid at the construction joint of the lower-layer outer wall and the upper-layer outer wall; and the waterproof roll layer is laid on the outer sides of the lower-layer outer wall, the waterproof roll reinforcing layer and the upper-layer outer wall. The method solves the problem that according to a conventional method for preventing leakage by arranging a water stop steel plate in a construction joint of a basement outer wall, the water stop steel plate is prone to rusting and being damaged in the construction process, and the anti-leakage performance is affected.
本发明公开了一种基坑地下室外墙施工缝防渗漏构造及其施工方法，包括：下层外墙，下层外墙的顶面的内缘形成有反坎；第一注浆管，埋设于下层外墙的顶面的中部，第一注浆管连接有注浆导管，注浆导管伸至下层外墙的内侧的外部；两个遇水膨胀止水带，埋设于下层外墙的顶面，两个遇水膨胀止水带分别设置于第一注浆管的相对两侧；上层外墙，浇筑于下层外墙的顶面和反坎上；防水卷材加强层，铺设于下层外墙和上层外墙的施工缝处；防水卷材层，铺设于下层外墙、防水卷材加强层和上层外墙的外侧。本发明解决了地下室外墙的施工缝中常规设置止水钢板进行防渗漏的方法，在施工过程中止水钢板易生锈和被破坏而影响防渗漏性能的问题。
