Supporting pile reinforcing structure located outside foundation pit and construction method of supporting pile reinforcing structure
The invention discloses a supporting pile reinforcing structure located outside a foundation pit and a construction method of the supporting pile reinforcing structure. The reinforcing structure comprises supporting piles surrounding the side wall of the foundation pit and further comprises anchoring piles located outside the foundation pit, a top beam is connected between the tops of the supporting piles, and the tops of the anchoring piles are connected with the top beam through reinforcing haunches. According to the construction method, firstly, construction of the supporting piles and the anchoring piles is completed, then reinforcement of the top beam and the reinforcing haunch is conducted, and the top beam and the reinforcing haunch are poured into a whole at the same time. The method has the beneficial effects that the structural design position of the anchoring pile ensures the larger top deformation resistance, the same support pile structure can be adopted, the construction is simple and convenient, and on-site implementation is easy; the reinforced haunch structure can adopt the same crown beam structure, construction is simple and convenient, and on-site implementation is easy. The reinforcing haunch structure can increase the tension on the crown beam, is connected with the anchoring pile, and can effectively reduce the deformation displacement of the top of the supporting pile.
本发明公开了一种位于基坑外部的支护桩加强结构及其施工方法。该加强结构包括围挡在基坑侧壁的支护桩，还包括位于基坑外部的锚固桩，支护桩的顶部之间连接有冠梁，锚固桩的顶部通过加强腋与冠梁连接。该施工方法首先完成支护桩和锚固桩的施工，然后进行冠梁和加强腋的配筋，冠梁和加强腋同时浇筑为一体。本发明的有益效果：锚固桩结构设计位置保证了其较大的顶部抗变形能力，可采用同支护桩构造，施工简便，易于现场实施；加强腋结构可采用同冠梁构造，施工简便，易于现场实施。加强腋结构可加大对冠梁的拉力，与锚固桩相连，可有效减少支护桩顶部的变形位移量。
