废泥浆压滤固化再利用处理技术

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，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，降低工程成本，提高了施工进度，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。

Abstract:

The bridge bored cast-in-place pile with positive and negative circulation rotary drilling technology generates 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 waste mud filter pressing, solidification and reuse treatment technology is selected, and the comparison of equipment selection, filter pressing, solidification process and reuse are analyzed, This process can avoid pollution to the environment and occupation of land resources caused by the traditional treatment of waste mud, reduce the project cost, improve the construction progress, realize the reuse of waste mud from pile foundation construction, and conform to the concept of high-quality green construction.
