DRAINING MATERIAL USED FOR IMPROVEMENT METHOD OF SOFT GROUND SUCH AS LANDFILL

摘要

PROBLEM TO BE SOLVED: To provide a fiber draining material which promotes subsidence of a soft ground by draining water content of the clay layer of the soft ground by a vertically arranged drain, which can stabilize the ground at an early stage by the ground subsidence by shortening the time without collapse or fracture, and which corrods naturally and does not harm environment.;SOLUTION: The fiber draining material 1 consists of an outer covering material 2 and a filler 3 of a core material. The outer covering material 2 is made of jute fiber woven cloth or non-woven fabric having permeability, and the filler 3 is made of a skin short length fiber of a shell of a coconut. The core material of the filler 3 is made of a short length fiber which is in a disentangled state, and the filler 3 is attached to the pervious outer covering material 2 made of the jute fiber woven cloth or non-woven fabric. The outer covering material 2 and the core material of the filler 3 attached to the inside of the outer covering material 2 are sewn and integrated together by a thread 5 of natural fiber such as a cotton thread in a plurality of positions of the outer covering material 2. Thus, the outer covering material 2 and the core material are made an extra-long fiber draining material 1.;COPYRIGHT: (C)2008,JPO&INPIT
