Construction method for silty clay stratum water-rich deep foundation pit
The invention discloses a construction method for a silty clay stratum water-rich deep foundation pit. The construction method for the silty clay stratum water-rich deep foundation pit comprises the following steps that S1, underground diaphragm wall construction is conducted; S2, dewatering and drainage construction is conducted; and S3, excavation and supporting are conducted, vertical layered excavation is adopted, excavation and supporting are conducted at the same time, step operation relay excavation is conducted, and deformation or collapse of the foundation pit is avoided. According tothe construction method, a foundation pit rigid fully-closed enclosure structure is formed through the underground diaphragm wall and inner supporting modes and serves as a supporting mode and a barrier-curtain of the foundation pit, and the stability of the foundation pit is ensured.
本发明公开了粉质黏土地层富水深基坑施工工法，粉质黏土地层富水深基坑施工工法，包括以下步骤：S1：地下连续墙施工，S2：降排水施工，S3：开挖支护，采用竖向分层开挖，随挖随撑，台阶作业接力开挖，避免基坑出现变形或坍塌。本申请通过地下连续墙+内支撑的形式为基坑钢性全封闭的围护结构，作为基坑的支护方式和截水帷幕，确保基坑稳定。
