WICK- DRAIN FOR CLAY SOIL IMPROVEMENT BY MEANS OF DEWATERING ACCELERATION IN THE GROUND

摘要

A nonwoven fabric drain that overlaps the nonwoven table with smooth drainage to be half width (1), sewns the needle needle (3) at the overlapping end in the depth direction, and forms the inside thereof so as to form a mesh cloth overlapping portion (2). (4), and cut into appropriate lengths as necessary, granular sciropol kernels (5), lightweight artificial gravel aggregate (5a), natural crushed soybean gravel (5b) inside the mesh-shaped overlapping portion (2) A wick drain for promoting dehydration of a viscous clay soft ground to produce a wick drain (7) having a structure for forming a drain wick (6) by filling drain water cores such as straw bundles (5c) separately or mixed with each other.
