Foundation pit excavation double-side existing pile foundation protection structure and design calculation method
The invention discloses a double-side existing pile foundation protection structure for foundation pit excavation and a design calculation method.The double-side existing pile foundation protection structure for foundation pit excavation comprises two sets of existing pile foundation bodies which are vertically arranged and symmetrically arranged on the two sides of a foundation pit; the horizontal supporting structure comprises a protection beam which is horizontally arranged, the protection beam is perpendicular to the existing pile foundation body, and pressure assemblies are installed at the two ends of the protection beam respectively; the vertical supporting mechanism is arranged in the foundation pit, and the top end of the vertical supporting mechanism is fixedly connected with the bottom face of the protection beam; the control system is mounted on the protection beam; the pressure sensing unit is installed at the output end of the pressure assembly. The horizontal supporting mechanism is matched with the vertical supporting mechanism to support the existing pile foundation body, and obvious influence on adjacent pile foundations in the foundation pit excavation process is avoided.
本发明公开一种基坑开挖双侧既有桩基保护结构及设计计算方法，包括：既有桩基本体，既有桩基本体竖向设置有两组，两组既有桩基本体对称设置在基坑的两侧；水平支撑结构，水平支撑结构包括水平设置的保护梁，保护梁与既有桩基本体之间垂直设置，保护梁两端分别安装有压力组件；垂直支撑机构，垂直支撑机构设置在基坑内，且垂直支撑机构的顶端与保护梁的底面固定连接；控制系统，控制系统安装在保护梁上；压力传感单元，压力传感单元安装在压力组件的输出端。本发明采用水平支撑机构配合垂直支撑机构对既有桩基本体进行支护，避免基坑开挖过程中对邻近的桩基产生显著的影响。
