A-shaped double-row-pile foundation pit supporting structure and construction method thereof
The invention discloses an A-shaped double-row-pile foundation pit supporting structure and a construction method thereof. The A-shaped double-row-pile foundation pit supporting structure comprises front-row piles and rear-row piles, and is characterized is that the front-row piles obliquely enter a soil body with the pile head pointing into a foundation pit; the rear-row piles are arranged vertically, or arranged obliquely with the pile heads pointing towards the outside of the pit; the tops of the front-row piles and the tops of the rear-row piles are connected through top beams; back-row pile surrounding purlins are arranged on one side, facing the inside of the foundation pit, of the back-row piles; inter-pile supports are arranged between the back-row pile surrounding purlins and thefront-row piles; and the bases of the front-row piles can be expanded as required. During implementation, the front-row piles, the back-row piles and the top beams are constructed firstly; the foundation pit is excavated further to the surrounding purlins and the support bottom; surrounding purlins and supports are constructed; and finally the bottom of the foundation pit is excavated. Compared with ordinary two-row piles, the A-shaped double-row-pile foundation pit supporting structure has the advantage of higher overall rigidity and higher lateral displacement resistance, and can be taken asthe supporting structure of a foundation pit with a relatively large excavation depth.
本发明公开了包括前排桩、后排桩，其特征在于前排桩倾斜进入土体，桩头指向基坑内；后排桩竖直设置，或桩头指向坑外方向倾斜布置；前排桩桩顶及后排桩桩顶通过冠梁连接，后排桩面向基坑内一侧施工后排桩围檩，后排桩围檩与前排桩之间设置桩间支撑。所述前排桩所述前排桩可根据需要进行扩底。实施时，首先施工前后排桩及冠梁；进一步基坑开挖到围檩及支撑底部；施工围檩及支撑；最后开挖到基坑底。本发明的优点是，相比一般双排桩具有更高的整体刚度，抗侧移能力更强。可以作为开挖深度较大基坑的支护结构。
