Independent large-span deep foundation pit prestressed steel supporting system
The invention discloses an independent large-span deep foundation pit prestressed steel supporting system. The system comprises a truss supporting system provided with at least one supporting beam, and the bottom of each supporting beam is provided with an inhaul cable system. The inhaul cable system comprises a plurality of V-shaped rods, the bottoms of the V-shaped rods are movably connected to inhaul cables through inhaul cable connectors, the two ends of the V-shaped rods are fixedly connected to the bottoms of the supporting beams through movable connectors correspondingly, and the two ends of the inhaul cables are movably connected to the bottoms of the supporting beams. The inhaul cable system arranged in the system not only can solve the self-weight problem of the truss supporting system, but also can promote that no steel stand column or concrete stand column pile exists in the foundation pit, the earth excavation efficiency is greatly improved, the construction period is shortened, and the supporting system can be repeatedly used and has the advantages of being short in construction period, low in cost, good in safety performance, environmentally friendly, free of pollution and the like.
本发明公开了一种独立式大跨度深基坑预应力钢支撑系统，包括设有至少一根支撑梁的桁架支撑系统，每根所述支撑梁的底部均设有一个拉索系统；拉索系统包括若干V形杆，V形杆的底部通过拉索接头与拉索活动连接，V形杆的两端分别通过活动接头与支撑梁底部固定连接，拉索的两端与支撑梁底部活动连接；本系统设置的拉索系统不仅能够解决桁架支撑系统的自重问题，还能促使在基坑内实现无钢立柱和混凝土立柱桩，大大提高土方开挖效率，节省工期,本支撑系统可重复使用，具有工期短、成本低、安全性能好、环保无污染等特点。
