Deep foundation pit dewatering construction method for thin-wall plastic concrete seepage interception wall
The invention discloses a dewatering construction method for a deep foundation pit with a thin-wall plastic concrete seepage-stopping wall, which organically combines the thin-wall plastic concrete seepage-stopping wall and deep well dewatering, the depth of the thin-wall plastic concrete seepage-stopping wall reaches 30m, a dewatering deep well with the depth of 28m is arranged in the seepage-stopping wall, and the bottom of the seepage-stopping wall extends into an impervious layer, so that the hydraulic connection inside and outside the foundation pit is blocked; under the dewatering and drainage effects of the dewatering deep well, the underground water level in the foundation pit is rapidly and effectively reduced, the engineering construction progress is ensured, the construction cost is reduced, remarkable economic and social benefits are achieved, more high-pressure rotating (swinging) spraying walls are adopted for traditional underground seepage interception, and more underground soil layers are layered in the engineering. The problems that rotary (swinging) spraying walls of different soil layers are poor in uniformity and high in underground water level fall, damage is prone to occurring, and wall reliability is not high, and plastic concrete seepage interception walls are good in durability, high in seepage prevention efficiency and high in reliability are solved.
本发明公开了薄壁塑性混凝土截渗墙深基坑降水施工工法，采用薄壁塑性混凝土截渗墙与深井降水的有机结合，薄壁塑性混凝土截渗墙深度达30m，截渗墙内布置深度28m的降水深井，由于截渗墙底部伸入不透水层，阻断了基坑内外水力联系，在降水深井降排水作用下，快速有效降低了基坑内地下水位，确保了工程施工进度，降低了施工成本，具有显著的经济和社会效益，传统地下截渗采用高压旋(摆)喷墙较多，本工程地下土层分层较多。针对不同的土层旋(摆)喷墙的均匀性较差，地下水位落差较大时，易发生破坏，墙体可靠性不高，而塑性混凝土截渗墙耐久性较好，防渗效率较高，可靠性高。
