BANKING CONSTRUCTION METHOD UTILIZING BACKFILLING MATERIAL SUCH AS FLUIDIZED SOIL, PIT SAND, LOCAL SOIL AND CRUSHED STONE

摘要

PROBLEM TO BE SOLVED: To solve a problem wherein there are various construction methods in the case of constructing a road or the like on a slope, in a mountain area, or the like but every construction method has merits and demerits and there is no method allowing construction conformed to the ground and taking environment into consideration.;SOLUTION: This banking construction method utilizing a backfilling material such as fluidized soil comprises processes of shaping the ground, excavating the ground and installing a wall surface material in an excavated space, burying the backfilling material such as fluidized soil, pit sand, local soil and crushed stones between the ground surface and the wall surface material, repeating the wall surface material installation and backfilling processes up to a predetermined height, and covering the upper part of the backfilling material with water impermeable fluidized soil or the like mixed with construction produced soil, soil, a polymer, and the like for the construction of a pavement road or the like. This construction method can cope with various grounds, shorten a construction period, perform construction taking environment into consideration, prevent ground settlement and fluctuation caused by drainage, and adjust the presence of a drainage facility and a reinforcing material to permit construction conformed to the ground.;COPYRIGHT: (C)2006,JPO&NCIPI
