Construction method of deep and large foundation pit supporting system
The invention discloses a construction method of a deep and large foundation pit supporting system. The construction method comprises the following steps that the thickness of a cement-soil stirring wall and the section size and height of a steel underground diaphragm wall are determined; grooving construction is conducted, and water is injected to the designed depth; injecting cement paste and synchronously stirring to form a cement-soil stirring wall; and the H-shaped steel is lifted and inserted into the cement-soil stirring wall, the adjacent H-shaped steel is spliced through the locking opening structures, and the steel underground diaphragm wall is formed. According to the deep and large foundation pit supporting system constructed through the method, seepage prevention can be achieved through the cement-soil stirring wall, most of soil pressure can be borne through the steel underground diaphragm wall, and the two functions of water stopping and soil retaining are achieved. The steel underground diaphragm wall is formed by splicing lock catch structures, and the rigidity of the structure is improved. The deep and large foundation pit supporting system constructed through the method has the advantages of being stable in quality, good in supporting effect, convenient to construct, high in construction speed, high in operability and high in practicability, and the H-shaped steel is convenient to recycle.
本发明公开了一种深大基坑支护体系的施工方法，包括如下步骤：确定水泥土搅拌墙厚度、钢制地下连续墙截面尺寸和高度；进行成槽施工，注水至设计深度；注入水泥浆并同步搅拌形成水泥土搅拌墙；起吊H型钢，将H型钢插入水泥土搅拌墙中，相邻的H型钢通过锁口结构拼接，形成钢制地下连续墙。通过本方法施工的深大基坑支护体系，能够通过水泥土搅拌墙防渗，通过钢制地下连续墙承受大部分土压力，兼备止水和挡土两大功能。钢制地下连续墙通过锁扣结构拼接而成，提升了结构的刚度。该方法施工的深大基坑支护体系具有质量稳定、支护效果好、施工便捷、施工速度快、H型钢便于回收利用、操作性强、实用性强的优点。
