摘要： PROBLEM TO BE SOLVED: To drain the rainwater passing through a water-permeable structure layer by braiding a resin monofilament into many layers to form a net-like structure. SOLUTION: A monofilament 1 is braided to form a resin conducting tube 2 having a net-like structure and the inner diameter of 5-125 mm, and an outer tube 4 (monofilament braided layer) is overlapped and is braided on an inner tube 3 (monofilament braided layer). The low-contraction type resin monofilament 1 preferably having the heat contraction factor of 10% or below is optimum. The monofilament diameter is preferably set to 0.2-5 mm. The monofilament 1 is braided with an 8-64-spindle braider to form the inner tube 3, the outer tube 4 is formed on it by similar braiding, and a resin conducting tube with a multi-layer net-like structure can be obtained. The resin conducting tube with the outer diameter of 35ϕ or above having a problem in the past can be coped with, and the drainage capability can be improved by diameter expansion.
