Foundation pit prestress supporting system and construction method thereof
The invention provides a foundation pit prestress supporting system and a construction method thereof. The foundation pit prestress supporting system comprises steel supports, latticed columns, joists, portal frames, connecting beams, hanging plates and supporting arches. The steel supports apply prestress in the horizontal direction to the foundation pit support structure in the axial direction; the latticed column is of a cavity structure and is used for being placed in a foundation pit to vertically bear the supporting system. The joists are erected on the latticed columns so as to carry the steel supports; the portal frame is arranged on the joist and surrounds the steel support to limit the movement of the steel support; the connecting beams are used for connecting the adjacent steel supports so as to enhance the rigidity of the supporting system; the hanging plate is used for connecting the end part of the steel support and the foundation pit support structure; the supporting arches are arranged at the positions, bearing the joists, of the latticed columns. According to the prestress supporting system and the construction method thereof, safe and effective supporting and protection can be conducted on an enclosure structure of a large-span foundation pit, construction safety is ensured, and the engineering construction efficiency, economic benefits and environmental benefits are improved through modularized recyclable assemblies and a standardized installation method.
本申请提供了一种基坑预应力支撑体系及其施工方法，包括钢支撑、格构柱、托梁、门式架、联系梁、挂板、撑拱。钢支撑沿轴向对基坑围护结构施加水平方向的预应力；格构柱为空腔结构，用于置入基坑内对支撑体系进行垂向承载；托梁架设在格构柱上，以对钢支撑进行托载；门式架设在托梁上并围设于钢支撑以限制钢支撑移动；联系梁对相邻的钢支撑分别交接，以增强支撑体系的刚度；挂板用于连接钢支撑端部与基坑围护结构；撑拱设置在格构柱承载托梁的位置。该预应力支撑体系及其施工方法可对大跨度基坑的围护结构进行安全有效的支撑防护，确保施工安全，并通过模块化的可回收再使用组件以及规范化的安装方法，提高了工程建设施工效率、经济效益以及环境效益。
