Anti-deviation pile construction method under flow-plastic sludge geological condition
The invention relates to an anti-deviation pile construction method under the flow-plastic silt geological condition. The method comprises the steps that firstly, soft soil in the silt geological condition is improved before pipe pile construction; secondly, before the pipe pile is implemented, anti-extrusion ditch and stress release hole construction is carried out; thirdly, quality monitoring is conducted in the pipe pile construction process; 4, quality monitoring is conducted in the earth excavation project; and fifthly, displacement monitoring is conducted in the pipe pile construction process. The invention provides a construction method for effectively preventing pile deviation and pile breakage in the PHC pipe pile construction process in the deep plastic silt geological state.
本发明涉及一种流朔性淤泥地质条件下防偏桩施工方法，步骤一：在管桩施工前对淤泥地质的软土进行改良处理；步骤二：管桩实施前，进行防挤沟和应力释放孔施工；步骤三：管桩施工过程中进行质量监控；步骤四：土方开挖工程中进行质量监控；步骤五：管桩施工过程中进行位移监测。本发明提出在深厚流朔性淤泥地质状态下，PHC管桩施工过程中，有效预防偏桩、断桩的施工方法。
