Horizontal drain for consolidation sinkage promotion of cohesive soil and consolidation sinkage promotion manner null

摘要

PROBLEM TO BE SOLVED: To provide a horizontal drain, in which water introducing properties are difficult to be damaged even by pressure by a fill, etc., and both remaining in a ground and dispersion and dissipation in the ground can also be selected by sorting raw materials and which has excellent water-introducing and drainage functions and can also be followed up to the distortion and deformation of the ground, as the horizontal drain substituted for conventional sand mats. ;SOLUTION: Fillers 2 consisting of fiber mats, in which natural rubber or synthetic rubber latex-shaped adhesives are attached to natural fibers such as coconut fibers or synthetic fibers, entangled with a nonwoven fabric shape or a three-dimensional braided shape and formed in a mat shape, is coated with woven fabric-shaped or nonwoven fabric-shaped skin material 3 composed of natural fibers such as jute or the synthetic fibers and having water permeability.;COPYRIGHT: (C)1999,JPO
