T-shaped plate support enclosure system for deep foundation pit and construction method
The enclosure system comprises a plate support structure and an underground structure, the plate support structure is arranged in the deep foundation pit, the upper portion of the plate support structure is located within the range of the deep foundation pit, the lower portion of the plate support structure is located in an underground soil body, and the underground structure is arranged in the deep foundation pit and located in the plate support structure; the plate support structure comprises T-shaped plate supports, the T-shaped plate supports are connected end to end and arranged in the deep foundation pit in a surrounding mode, and the underground structure is connected with the T-shaped plate supports. According to the T-shaped plate support, the enclosure sheet piles serve as structural outer walls, the enclosure sheet piles and the structural outer walls are combined, the dual functions of enclosure and outer walls are achieved, the supporting sheet piles have the dual functions of supporting and support changing, the supporting function of a deep foundation pit is achieved, the supporting sheet piles serve as support changing structures, construction of an underground structure is not affected, and the construction efficiency is improved. The construction period is greatly shortened, the construction cost is greatly reduced, the construction efficiency is improved, and the overall stability and safety of the structure are good.
本发明公开了一种用于深基坑的T型板撑围护体系及施工方法，围护体系包括板撑结构和地下结构，板撑结构设在深基坑中，其上部位于深基坑范围内，下部位于地下土体中，地下结构设在深基坑中，并位于板撑结构中；板撑结构包括T型板撑，T型板撑首尾相连围设在深基坑中，地下结构与T型板撑连接。本发明的T型板撑中的围护板桩兼做结构外墙，实现围护板桩和结构外墙的两墙合一，具有围护和外墙的双重作用，支撑板桩具有支撑和换撑的双重作用，既满足深基坑的支撑作用，又兼做换撑结构，不影响地下结构的施工，大幅降低施工周期及施工成本，提升施工效率并且结构整体的稳定性和安全性好。
