摘　　要：采用正反循环回旋钻技术成孔的桥梁钻孔灌注桩,施工过程中会产生大量的废泥浆,传统的处理方式如直接排放、就地填埋、集中外运等都会对环境造成极大影响,选用废泥浆压滤固化再利用处理技术。从设备选型对比、压滤固化流程及再利用等方面进行分析后,认为此工艺可以避免废泥浆采用传统方式处理对环境造成的污染及对土地资源的侵占,并能降低工程成本,提高了施工进度,从而实现对桩基施工废泥浆的重复利用,符合高质量绿色施工的理念。The bridge bored-in-place pile made by the positive and negative circulation rotary drilling technology will produce a large amount of waste mud during construction.The traditional treatment methods,such as direct discharge,on-site landfill and centralized outward transportation will have a great impact on the environment.The pressure filtration,curing and reuse treatment technology of waste mud is selected.By comparing the equipment types,and analyzing the pressure filtration curing process and reuse,it is considered that this technology can avoid the pollution to the environment and the occupation of land resources caused by the traditional treatment methods of waste mud,reduce the engineering cost,improve the construction progress,realize the reuse of waste mud from the pile foundation construction,and conform to the concept of high-quality green construction.
