地下连续墙槽段宽度、垂直度检测在工程检测中的应用

Application of Checking Underground Continuous Wall Troughs Width and Verticality in Engineering Testing

结合某工程地下连续墙逆作法施工实例,分析了地下连续墙槽段宽度、垂直度检测方法及原理,介绍了泥浆波速的测定和槽宽、垂直度计算方法,对检测数据的分析和研究表明,通过成孔质量检测可以将施工隐患消除于成桩前,其效果良好。

Taking a reverse construction practice of underground continuons wall as example,it analyses the checking method and principle of underground continuous wall troughs width and verticality,introduces the checking of mud wave velocity and calculation of troughs width and verticality. The data test and analytic resuits show that construction accident can be eliminated before pile finished.
