Foundation pit waterproof curtain structure construction method
The invention relates to the technical field of foundation pit construction water stopping, in particular to a foundation pit water stopping curtain structure construction method which comprises the steps that fender post construction is conducted, multiple sets of first pile holes are drilled in the periphery of a foundation pit at intervals according to the foundation pit range, concrete is poured into the first pile holes to form fender posts, and multiple sets of second pile holes are drilled in the sides, away from the foundation pit, of the first pile holes at intervals; each set of second pile holes intersect with the two adjacent sets of first pile holes, concrete is poured into the second pile holes to form water stop piles, formworks are installed on the inner sides of the tops of the fender posts and the outer sides of the tops of the water stop piles, concrete is poured, the formworks are dismantled to form top beams, and foundation pits are dug in the inner sides of the fender posts. And a waterproof curtain is formed, so that underground water naturally flows around the left side and the right side of the foundation pit, the overall seepage field of the underground water is not changed, the safety and the reliability of the peripheral structure of the foundation pit are guaranteed, the production efficiency, the prefabrication precision and the result quality are remarkably improved, and construction is convenient and rapid.
本发明涉及基坑施工止水技术领域，具体为一种基坑止水帷幕结构施工方法，包括围护桩施工，根据基坑范围在基坑四周间隔钻设多组桩孔一，在桩孔一内浇筑混凝土形成围护桩，桩孔一远离基坑一侧间隔钻设多组桩孔二，每组桩孔二与相邻两组桩孔一相交，在桩孔二内浇筑混凝土形成止水桩，在围护桩顶部的内侧和止水桩顶部的外侧安装模板并浇筑混凝土，拆除模板形成冠梁，在围护桩内侧挖设基坑，本发明通过采用止水桩与围护桩相交，挤密，形成一道止水帷幕，使得地下水从基坑左右两侧产生自然绕流，达到不改变地下水总体的渗流场，保证了基坑周边结构的安全性和可靠性，生产效率、预制精度、成果品质均得到显著提升，施工方便快速。
