The invention relates to a prestressed concrete supporting system which comprises enclosing purlins, steel strands and tensioning assemblies, the enclosing purlins are horizontally arranged on an enclosure, the steel strands are arranged on the enclosing purlins, and the tensioning assemblies are connected with the steel strands and used for tensioning the steel strands. According to the prestressed concrete supporting system, lateral supporting force of the concrete supporting system can be increased or decreased according to actual working conditions in the foundation pit excavation process, automatic monitoring and alarming are achieved, it is ensured that overall deformation of a foundation pit is safe and stable, and deformation of various surrounding environments does not exceed control; and through the prestress servo technology, the supporting amount in the concrete supporting system design is reduced, then the manufacturing cost is reduced, site construction is facilitated, and the foundation pit construction efficiency is improved.
本发明涉及一种预应力混凝土支撑体系，包括：围檩、钢绞线和拉紧组件，多个所述围檩水平设置于围护上，所述钢绞线设置于所述围檩上，且所述拉紧组件连接所述钢绞线，用于拉紧所述钢绞线。本发明提供的预应力混凝土支撑体系，可使混凝土支撑体系在基坑开挖过程中根据实际工况增减侧向支撑力、自动监测与报警，确保基坑整体变形安全稳定，实现周边各类环境变形不超控；且通过预应力伺服技术，减少了混凝土支撑体系设计中的支撑量，进而减少了造价，便于现场施工，提高了基坑施工效率。
