VERTICAL DRAIN FOR SOFT FOUNDATION TREATMENT, APPARATUS AND METHOD FOR MANUFACTURING THE SAME

摘要

PURPOSE: A vertical drain for treating soft ground, a device and a method for manufacturing the vertical drain are provided to improve tensile strength and compressive strength of the vertical drain. CONSTITUTION: A vertical drain(10) for treating soft ground comprises a coir sheet(11) and a jute sheet(12). The coir sheet is manufactured by mixing and compressing coconut fiber and natural latex. The jute sheet is formed to cover the coir sheet and permeate pore water in soft ground. Water flowing grooves(112) are formed in one surface of the coir sheet. Protrusions(113) are formed in a longitudinal direction of the coir sheet.
