To provide a conducing 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 braided layer made of monofilament on a surface of a spring pipe.

In a system in which a waterproof layer is proved on various floor boards made of reinforced concrete, steel, etc., and a conducting pipe is arranged on the waterproof layer which is a side fringe part of a road to drain rainwater, the conducting pipe consists of a spring pipe 1 and a layer 2 braided by using monofilaments. A metallic pipe or a resin pipe which has excellence in 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, monofilament is used on the assumption that it is braided, its diameter is 0.2 to 2mm, preferably, 0.5 to 1.5mm, and polyester resin, polypropylene resin, etc., are used as its raw material to prevent the entry of sand and gravel into the pipe due to the asphalt pavement.
