Double-row micro pile foundation pit supporting structure and construction method
The invention belongs to the technical field of foundation pit supporting, and particularly relates to a double-row micro pile foundation pit supporting structure and a construction method, two rows of micro steel pipe piles are sequentially arranged on the outer edge of a foundation pit, and the two rows of micro steel pipe piles are respectively front-row micro piles and rear-row micro piles; the upper ends of the front-row micro piles and the rear-row micro piles are connected through a connecting part; a concrete face plate layer is arranged on the side wall of the foundation pit, a reinforcing mesh is arranged in the concrete face plate layer, and the reinforcing mesh is connected with the front-row micro piles through connecting pieces. Compared with the prior art, the double-row micro pile foundation pit supporting structure has the beneficial effects that (1) compared with a soil nailing wall supporting structure, the double-row micro pile foundation pit supporting structure is small in occupied space and small in influence on the surrounding environment; (2) the double-row micro piles play a role in retaining soil, the double-row micro piles are connected into a whole through the top beam and the connecting beam, the whole resists water and soil pressure of a foundation pit and a side slope, and the concrete panel layer protects the slope surface;
本发明属于基坑支护技术领域，具体涉及一种双排微型桩基坑支护结构及施工方法，基坑外沿依次设两排微型钢管桩，两排所述微型钢管桩分别为前排微型桩和后排微型桩；所述前排微型桩和后排微型桩的上端通过连接部连接；所述基坑侧壁设有混凝土面板层,所述混凝土面板层内包含钢筋网，所述钢筋网通过连接件与前排微型桩连接；相比现有技术，本发明的有益效果在于：(1)相比于土钉墙支护结构，本发明的双排微型桩基坑支护结构占用空间小，对周边环境的影响小；(2)双排微型桩起到挡土的作用，冠梁及连梁将双排微型桩连接成一个整体，整体抵抗基坑及边坡的水土压力，混凝土面板层保护坡面。
