Foundation pit construction method suitable for soft substratum
The invention discloses a foundation pit construction method suitable for a soft substratum. The method comprises the following steps that a waterproof curtain is constructed at the boundary positionof a foundation pit to be subjected to excavation, supporting piles are constructed on the inner side of the waterproof curtain, and the waterproof curtain and the supporting piles go deep into the soft substratum; multiple underground diaphragm walls perpendicular to the excavation longitudinal direction of the foundation pit are constructed in the longitudinal direction of the foundation pit tobe subjected to excavation, the bottoms of the underground diaphragm walls go deep into the soft substratum, and multiple composite foundation piles are constructed between the adjacent underground diaphragm walls; multiple reinforcing columns are constructed on the inner sides of the supporting piles, the reinforcing columns are fixedly embedded between the underground diaphragm walls and the supporting piles, and the bottom ends of the reinforcing columns go deep into the soft substratum; and foundation pit excavation is conducted until the first set depth is reached. According to the construction method, a supporting structure is high in reliability, and the cost is low.
本发明涉及一种适用于软弱下卧层的基坑施工方法，包括以下步骤：在待开挖基坑的边界位置处施工防水帷幕，在防水帷幕的内侧施工支护桩，防水帷幕和支护桩深入软弱下卧层；沿待开挖基坑纵向施工多道垂直于基坑开挖纵向的地下连续墙，地下连续墙底部深入软弱下卧层，在相邻地下连续墙之间施工多个复合地基桩；在支护桩内侧施工多个加强柱，加强柱嵌固在地下连续墙与支护桩之间，加强柱的底端深入软弱下卧层；基坑开挖，开挖至第一设定深度，本发明的施工方法支护结构可靠性高、费用低。
