METHOD OF CONSTRUCTING GROUND OF LANDFILL WITH DERDGED SOIL FOR TREE PLANTING

摘要

PURPOSE: A constructing method of the ground from landfills with dredged soil for tree planting is provided to reduce the stabilization period for soft ground formed with the dredged soil. CONSTITUTION: A constructing method of the ground from landfills with dredged soil for tree planting comprises the following steps: digging the dredged soil from a reclaimed ground surface layer into the predetermined depth; spread a drainage layer material selected from gravels, wood chips, or a first soil improver on the dug up space to form a drainage layer; preparing a vegetating soil composition by mixing the dredged soil with a second soil improver, and installing the composition on the drainage layer to form a vegetation layer; planting trees on the vegetation layer; and sowing seeds on the vegetation layer for fixing the surface of the ground.
