Abstract
A device and method for mud solidification based on electro-osmosis well points cooperating with well-points dewatering. The method includes the following steps: 1) preparation; 2) construction of well point pipe positioning frame beams; 3) assembly of a mobile trestle platform; 4) well point pipe arrangement; 5) well point/electro-osmosis dewatering; 6) filtrate treatment; 7) well point pipe dismantling; and 8) excavation and transportation of solidified drilling slag for utilization. According to the disclosure, well point pipes are adopted and used as an anode and a cathode of an electro-osmosis well, and on-site quick solidification of pile foundation mud is implemented through the electro-osmosis combined with light well-points dewatering; by the adoption of the well point pipe positioning frame beams, the problems that drilling slag in a sedimentation tank has a large water content and it is difficult to arrange and fix the well point pipes are well solved.
