METHOD FOR LAND-FORMING GROUND IN WATER

摘要

PROBLEM TO BE SOLVED: To inhibit the formation of transition layers on soil-layer boundary sections, and to ensure layer boundaries in a method for land-forming a ground by forming a plurality of soil layers having different grain sizes in water under a divided state.;SOLUTION: In the method for successively charging borrow materials 3, 4 and 18 in which the grain sizes are conformed into water and land-forming the ground composed of a plurality of the soil layers having the different grain sizes in water, sheets 14 and 16 disassembled in response to the lapse of time are laid on the boundary sections of the soil layers and sections among the soil layers are partitioned.;COPYRIGHT: (C)2003,JPO
