摘要
某110 kV电塔由于杆塔周边发生塌方,影响原有桩基承载力,导致该构筑物出现倾斜。基于最新地质钻探报告以及现场周边环境进行分析,对该塔的基础采用增加微型钢管灌注桩加固以及对该塔进行顶升纠偏施工,使该电塔的基础承载力、塔杆倾斜率均满足现行相关规范要求。此施工方法在该工程中取得良好的效果,对类似工程问题具有重要的参考意义。
Due to the collapse around the 110 kV electric tower,the bearing capacity of the original pile foundation is affected.This results in the inclination of the structure.Based on the latest geological drilling report and the analysis of the surrounding environment of the site,the foundation of the tower is strengthened by adding micro steel pipe cast-in-place pile and the tower is lifted to correct deviation.Therefore,the foundation bearing capacity and tower inclination rate of the tower can meet the requirements of the current relevant specifications.This construction method has achieved good results in this project and can be served as a reference to solve similar engineering problems.
