CULVERT DRAIN PIPE AND CONSTRUCTION METHOD FOR CULVERT DRAIN PIPE

摘要

PPROBLEM TO BE SOLVED: To provide a culvert drain pipe capable of being simply constructed at construction site, allowing its pipe diameter to be freely adjusted, being bent, requiring no joint even if the pipe is long, and dispensing with pebbles, gravel, sand or the like in its construction work. PSOLUTION: In the construction method for the culvert drain pipe, a long sheet for the culvert drain pipe formed by integrating a water permeable resin layer and a nonwoven fabric layer to each other is prepared is transported to the construction site in a rolled-sheet form, pulled out from the roll in accordance with a shape of the construction site, and cut to the required length. The cut portion of the sheet is wound like a roll so as to match the pipe diameter of the required culvert drain pipe, and fastened by binding materials at a predetermined interval to construct the culvert drain pipe having sufficient strength and draining performance and dispensing with pebbles, gravel or the like in its construction work.
