METHOD FOR MIXING AND DISPOSING OF COAL ASH FOR EARLY STABILIZING DREDGED CONSTRUCTING FILL GROUND

摘要

PURPOSE: A coal ash mix-disposal method for the early stabilization of dredged and reclaimed soil is provided to improve the sedimentation and self-weight consolidation speed of the dredged and reclaimed soil. CONSTITUTION: A coal ash mix-disposal method for the early stabilization of dredged and reclaimed soil comprises the following steps: mixing 90~10wt% of dredged soil and 10~90wt% of coal ash to obtain coal ash mixed process soil(S110); adding seawater to the coal ash mixed process soil(S120); inserting the coal ash mixed process soil into a disposal facility for precipitating(S130); removing surface water from the facility using a wasteway(S140); and improving the ground property of the obtained dredged and reclaimed soil using a drainage method of pore water(S150).
