树根桩与压力注浆联合技术在基础加固工程中的应用

项目开工建设前,进行岩土工程勘察工作是工程建设的基本程序。本文介绍了某百米高SDH微波通讯铁塔因套用邻近场地岩土工程勘察资料,基础施工时采用不正确施工工艺,施工各方主体质量监管意识不严,最终造成地面塌陷,基础下形成空洞,给变形要求十分严格的通讯铁塔造成极大安全隐患,并最终采用树根桩与压力注浆联合技术成功补强加固的一个典型工程实例。

geotechnical engineering investigation is the basic construction procedures before the project starts to be constructed. This paper introduces a typical engineering examples .a 100-meter high SDH microwave communication iron tower, for applied mechanically to reconnaissance material of the nearby ground project, adopted an inaccurate construction craft in foundation construction, furthermore all quarters' main body of construction had not strict consciousness in quality supervision , ultimately resulted in coming forth ground subsidence and under foundation formed empty, That caused great potential safety problems for the communications tower which needs for rigorous deformation requirements. Finally adopted root pile and pressure grouting joint technology was a successful reinforcement and strengthening to the project.
