Artificial freezing method soft foundation pit construction structure
The invention discloses a soft foundation pit construction structure adopting an artificial freezing method. The soft foundation pit construction structure comprises a cold environment protection structure, a surface layer supporting freezing system, a secondary layer freezing supporting system and a bottom layer freezing supporting system. The secondary layer freezing supporting system is arranged on the top of the bottom layer freezing supporting system, the surface layer supporting freezing system is connected with the top of the secondary layer freezing supporting system, and the cold environment protection structure is arranged on the upper portion of the surface layer supporting freezing system. The method is used for advanced reinforcement of the deep and large foundation pit soil body in the soft soil area, the advanced reinforcement efficiency of the foundation pit soil body can be improved, the strength reinforcement effect and the anti-seepage effect of the foundation pit are enhanced, green low-carbon construction is achieved, the adverse effect of foundation pit excavation on adjacent buildings is reduced, and the project investment and the operation management and maintenance cost are optimized.
本发明公开了一种人工冻结法软基坑施工结构，它包括有冷环境保护结构、面层支护冻结系统、次层冻结支撑系统及底层冻结支撑系统；所述次层冻结支撑系统布置在所述底层冻结支撑系统的顶部，所述面层支护冻结系统与所述次层冻结支撑系统的顶部连接，所述冷环境保护结构布置在所述面层支护冻结系统的上部。本发明用于软土地区深大基坑土体的超前加固中，能提高基坑土体超前加固效率，增强基坑的强度加固效果及防渗效果，实现绿色低碳施工，减小基坑开挖对临近建筑的不利影响，并优化工程投资及运行管理维护费用。
