How to Install hollow drain material consolidated for joint material, material of the drain and drain material

摘要

PURPOSE: To improve the execution performance by connecting the edge part of a drain member for draining the soil water by a joint member which has a star shaped section and has at least three partitioning walls in the longitudinal direction and burying the drain members into the soil. ;CONSTITUTION: A joint member 2 which is made of synthetic resin, metal, etc., and has a stripe groove 4 consisting of at least three partitioning walls 3 is installed, and a projection 6 having a height of 0.2mm or more is installed at the center of the edge part of the partitioning wall. Then, a hollow drain member 1 consisting of unglazed pottery cylinder, synthetic fiber fused cylinder, etc., is formed. Then, a long drain member is formed by inserting the joint 2 to the position of the projection 6, at the edge parts of a plurality of drain members 1. Further, the connection edge of the drain member 1 is closely attached by a binder, thermal fusion, etc., and the outer periphery of the connection part is sealed by the nonwoven fabric, shrink tube 8, etc. Further, the long drain member 1 is embedded through insertion and striking in the case having a much water content, and drainage work is performed. Accordingly, connection can be carried out in simple and sure manner, and the water permeability of the connection part can be secured, and breakage and deformation can be prevented, and the intrusion of fine soil particles, etc., can be prevented.;COPYRIGHT: (C)1993,JPO&Japio
