Steel cross brace axial force system for controlling deformation of foundation pit latticed column and construction method
The invention discloses a steel cross brace axial force system for controlling deformation of a foundation pit latticed column and a construction method, and relates to the technical field of deep foundation pit construction.The steel cross brace axial force system for controlling deformation of the foundation pit latticed column comprises a foundation pit enclosure structure, the latticed column and a steel cross brace servo axial force system, and the latticed column comprises angle steel and batten plates; the steel cross brace servo axial force system comprises a steel jacket box, an inserted steel cross brace, a deformation monitoring sensor, a monitoring system and a hydraulic jack. The deformation control method is good in deformation control effect and high in precision, the phenomenon that the vertical stress capacity is weakened due to deformation of the latticed column can be prevented, the stability of the foundation pit is ensured, and the safety of foundation pit construction is ensured.
本发明公开了一种控制基坑格构柱变形的钢横撑轴力系统及施工方法，涉及深基坑施工技术领域，一种控制基坑格构柱变形的钢横撑轴力系统，包括：基坑围护结构、格构柱和钢横撑伺服轴力系统，所述格构柱包括：角钢和缀板；所述钢横撑伺服轴力系统包括：钢套箱、插接钢横撑、变形监测传感器、监控系统和液压千斤顶。本发明变形控制效果好，精度高，可防止格构柱变形导致竖向受力能力削弱现象的发生，确保基坑的稳定，保证基坑施工的安全。
