Drainage pipes for civil engineering works

Abstract

This item is a drainage pipe made of synthetic resin used in slope reinforcement work. As shown in reference diagram (1) showing the state of use, this item is installed on slope P by abutting the slanted rear end face against slope P, or by burying the rear end portion in the surface layer of slope P and engaging the wire strips of wire mesh N laid on slope P with the slits S, S on the left and right sides, and then spraying mortar M onto slope P. Also, as shown in reference diagram (2) showing the state of use, it can also be installed on slope P with a support bracket C attached to the rear end inside, with a filter F made of synthetic resin nonwoven fabric or the like fixed to it.
