PIPE AND CONDUCTING PIPE

摘要

PROBLEM TO BE SOLVED: To provide a conducting pipe which is used in, particularly, an asphalt paved road, drains rainwater which permeates therein efficiently, and does not cause the reduction of the performance due to the entry of sand and gravel and crushing of the pipe by providing a resin netlike multiporous layer on a surface of a spring pipe. SOLUTION: In a system in which a waterproof layer is provided on various flow boards made of reinforced concrete, steel, etc., and a water conducting pipe is arranged on the waterproof layer which is a side fringe part of a road to drain rainwater, the conducing pipe consists of a spring pipe 1 and a resin netlike multiporous layer 2. A metallic pipe or a resin pipe which has excellent flexibility and pressurizing resistance may be used as the spring pipe 1, and an inside diameter and an outside diameter of the pipe 1 are preferably 1 to 99mm and 1.4 to 100mm, respectively. Moreover, a multiporous wrapping body having a triangular or square or pentagonal or hexagonal mesh structure is preferably used as the resin netlike multiporous layer 2, and a diameter of monofilament which constitutes a mesh is 0.05 to 2mm to prevent the entry of sand and gravel into the pipe due to the asphalt pavement.
