STABILIZING CONSTRUCTION FOR SURFACE LAYER FOR POOR SUBSOIL

摘要

PURPOSE:To form a surface layer with less settlement at the time of working a load, on poor subsoil, by laying bag units with front and back sides connected at equal intervals, on the poor subsoil, and by pressing mixed substance with soil and cement, in the bag units. CONSTITUTION:Out of the sheets 1, 2 of nylon or the like permeating no particles of cement or the like, bag units 5 are formed; the front the back side sheets 1, 2 are connected together with coupling strips 3, 4 at equal intervals on the whole surface. After the bag units 5 are laid on poor subsoil 6, the mixture of the water bearing silt of field soil and cement is pressed in the bag units 5 and is cured. As a result, a surface layer with less settlement at the time of working a load can be formed, and filling 7 can be executed on a road on the upper section of the surface layer.
