Embodiment Construction
[0013] Such as figure 1 , figure 2 As shown, the first embodiment of the solid-liquid separation process for bored pile waste mud provided by the present invention includes A, collecting bored pile waste mud and purifying treatment; B, carrying out inorganic flocculation treatment to the purified mud; After flocculation, the mud uses quicklime powder as a filter aid for filter aid treatment; D. Solid-liquid separation is performed on the mud after filter aid treatment. The concrete implementation of above-mentioned steps can adopt following mode:
[0014] Step A, mud purification
[0015] The effect of mud purification can be achieved by any one of the three methods of natural sedimentation of mud, installation of steel mesh at the inlet of the mud pump, and sand removal by a desander, or all combinations of the three methods. The purpose: to adjust mud performance indicators through mud purification, The mud that meets the requirements of hole formation is recycled to red...
