Spliced prestressed water-stop arch-shaped pile enclosure structure and construction method thereof
The invention relates to a spliced prestressed water-stop arch-shaped pile enclosure structure and a construction method thereof. The enclosure structure is suitable for soil retaining and water stopping of foundation pit enclosure, semicircular grooves are formed in the two sides of prestressed arch-shaped piles, reinforcing steel bars are arranged in pile bodies, steel plates are embedded in thepile bodies, the steel plates can be welded to profile steel outside the pile bodies to form an enclosure system with the water stopping and soil retaining functions, and the shear capacity, the pilesinking positioning function and the overall structural performance of the system are improved. According to the spliced prestressed water-stop arch-shaped pile enclosure structure and the construction method thereof, the pile sinking process can be achieved through a static pressure method, a hammering method, a vibration method and the like, compared with the prior art, the spliced prestressedwater-stop arch-shaped pile enclosure structure has the advantages of being short in construction period, self-waterproof, free of pollution, low in noise, high in stability of the enclosure structure, low in construction cost, small in influence on the surrounding environment and the like.
本发明涉及一种拼接式预应力止水拱形桩围护结构及其施工方法。该围护结构适用于基坑围护挡土止水，所述的预应力拱形桩在两侧设有半圆形凹槽，在桩体内配有钢筋并预埋钢板，可与桩体外部型钢焊接，形成一个兼备止水与挡土功能的围护体系，提高该体系的抗剪能力、沉桩定位功能及整体结构性能。本发明沉桩过程可通过静压法、锤击法、振动法等来实现。与现有技术相比，本发明具有施工周期短、自防水、无污染、低噪音、围护结构稳定性强、工程造价低、对周围环境影响小等优点。
