Foundation pit reinforcing and supporting structure and method based on high-pressure jet grouting piles
The foundation pit reinforcing and supporting structure based on the high-pressure jet grouting piles comprises a transverse framework assembly and the main high-pressure jet grouting piles, a supporting assembly is connected into the transverse framework assembly, and elastic supporting compensation assemblies are arranged in end openings of the two ends of the supporting assembly in a sleeved mode; longitudinal framework assemblies are arranged between every two adjacent transverse framework assemblies, elastic switching assemblies are arranged between the longitudinal framework assemblies, and reverse jacking assemblies are rotationally connected to the positions, corresponding to the elastic switching assemblies, of the bottoms of the longitudinal framework assemblies. The anti-jacking assembly and the longitudinal framework assembly are matched with each other so that balance and stability between the high-pressure jet grouting piles in the longitudinal direction can be achieved. According to the high-pressure jet grouting pile, by arranging the transverse framework assembly and the longitudinal framework assembly, when the high-pressure jet grouting pile is subjected to external force, good counter-acting force can be achieved, the situation that local or large-area collapse occurs due to the situations such as inclination of the high-pressure jet grouting pile is avoided, and the stability of a foundation pit and the safety performance during construction are effectively improved.
本发明公开了一种基于高压旋喷桩的基坑加固支护结构，包括横向骨架组件和主高压旋喷桩，横向骨架组件的内部连接有支撑组件，支撑组件两端的端口内均套设有弹性支撑补偿组件；相邻两个横向骨架组件之间设置的纵向骨架组件，纵向骨架组件之间设置有弹性转接组件，纵向骨架组件底部对应弹性转接组件的位置转动接有反顶持组件，所述反顶持组件与纵向骨架组件彼此之间相互配合以实现高压旋喷桩彼此之间纵向上的平衡稳定。本发明中通过设置的横向骨架组件和纵向骨架组件，当高压旋喷桩受到外力作用时，能够起到良好的反作用力，避免其发生倾斜等情况导致发生局部或大面积塌方的情况，有效提高基坑的稳定性以及施工时的安全性能。
