Double-row pile and multi-layer composite three-dimensional fabric waterproof curtain integrated foundation pit supporting structure and construction method thereof
The invention relates to the technical field of building construction, and particularly relates to a double-row pile and multi-layer composite three-dimensional fabric waterproof curtain integrated foundation pit supporting structure and a construction method thereof. The double-row pile and multi-layer composite three-dimensional fabric waterproof curtain integrated foundation pit supporting structure comprises double rows of piles which are transversely arranged, and the double rows of piles comprise the front row of piles and the rear row of piles which are correspondingly arranged front and back; the front row of piles and the rear row of piles are each composed of a plurality of cast-in-situ bored piles, and the multiple cast-in-situ bored piles are evenly arranged at intervals and fixedly connected through crown beams; and a strip-shaped foundation trench is formed between the front row of piles and the rear row of piles, a plurality of reinforcement cages are arranged in the strip-shaped foundation trench and connected through reinforcement cage connecting devices, and concrete connecting beams are arranged above the reinforcement cage connecting devices. According to the double-row pile and multi-layer composite three-dimensional fabric waterproof curtain integrated foundation pit supporting structure and the construction method thereof, the mode that multi-layer composite three-dimensional fabric and the double rows of piles are combined is utilized, the problems that when stirring piles are constructed between the double rows of piles traditionally to serve as a waterproof curtain, the waterproof effect is poor, and construction is difficult are solved, the deformation resistance and the waterproof performance of the double rows of piles are improved, stress is coordinated, and the safer and more reasonable effects are achieved.
本发明涉及建筑施工技术领域，具体涉及一种双排桩与多层复合立体织物止水帷幕一体化基坑支护结构及其施工方法，包括横向设置的双排桩，双排桩包括前后对应设置的前排桩和后排桩；前排桩和后排桩均分别由若干根钻孔灌注桩构成，若干根钻孔灌注桩均匀间隔设置，若干根钻孔灌注桩之间通过冠梁固定连接；前排桩和后排桩之间开设有条形基槽，条形基槽内设有若干个钢筋笼，若干个钢筋笼之间通过钢筋笼连接装置连接，钢筋笼连接装置的上方设有混凝土连梁。本发明利用多层复合立体织物与双排桩结合的形式，解决了传统的在双排桩之间施工搅拌桩作为止水帷幕止水效果不好且施工困难的问题，提高了双排桩抵抗变形的能力和隔水性能，受力协调，更加安全合理。
