某工程钻孔灌注桩塌孔问题处理

Treatment of Borehole Collapse of Cast-in-situ Pile in a Project

在流塑状淤泥质粉质黏土层、粉质黏土夹粉砂层中进行钻孔灌注桩施工,容易造成钻孔灌注桩塌孔现象,采用合理的泥浆配置及适当加长护筒,可以有效地解决塌孔问题,经济合理地完成钻孔灌注桩的施工。

The construction of cast-in-situ pile in flow of plastic-like muddy soil and silty soil with silt sand is easy to cause the hole collapse.The problem of hole collapse can be effectively solved by reasonable slurry configuration and lengthening the casing pipe.The construction of cast-in-situ pile can be completed economically and reasonably.
