Construction method for stopping underground water of building foundation pit
The invention provides a construction method for stopping underground water of a building foundation pit. According to the construction method, a circle of water stop curtains are formed on the outer sides of support piles of the building foundation pit through a novel three-pipe method high-pressure jet grouting construction process; a circle of secant piles are formed on the inner sides of the support piles; a circle of dam foundation sand gravel curtains are formed between the support piles and the secant piles through a grouting construction process; and the water stop purpose is achieved through the combined action of the water stop curtains on the outer sides of the support piles, the secant piles on the inner sides of the support piles and the dam foundation sand gravel curtains. The method effectively solves the problem that the underground water flows into the building foundation pit, and is recognized by experts in the industry. Compared with a traditional precipitation method, the method has the advantages that the problem that the underground water flows into the building foundation pit is fundamentally prevented, the water stop effect is remarkable, the manufacturing cost is saved, the surrounding underground water level is not influenced, and the influence of the surrounding underground water level is avoided.
本发明提供一种建筑基坑地下水止水工法，即在建筑基坑支护桩的外侧通过新三管法高压喷射灌浆施工工艺形成一圈止水帷幕；在支护桩的内侧形成一圈咬合桩；在支护桩和咬合桩之间通过灌浆施工工艺形成一圈坝基砂砾石帷幕；通过支护桩外侧的止水帷幕、支护桩内侧的咬合桩和坝基砂砾石帷幕共同作用达到止水的目的。本发明有效地解决了建筑基坑涌入地下水的问题，得到业界专家的肯定。本发明与传统的降水法相比，不仅从根本上阻止了地下水涌入建筑基坑的问题，止水效果显著，而且，节省造价，对周围地下水位没有影响，且不受周围地下水位的影响。
