以某高铁路基工程为例,针对CFG桩清泥处理时机选择进行了研究,结合管内泵压混合料灌注流程,分别阐述了钻泥清理方法选择和湿法机械清理钻泥时机选择,并指出了清理钻泥注意事项,以指导今后CFG桩施工。 Taking a high-speed railway subgrade project as an example, the timing selection of clear mud disposal for CFG piles was studied. Combined with the injection process of pump mixed pressure in the pipe, the selection of drilling mud cleaning methods and the timing of wet mud removal drilling were elaborated. Drilling mud note to guide future CFG pile construction.
