Abstract

PURPOSE: To provide a drainage pipe which is manufactured such that a right and a left thick plastic selan thread are fushion-welded at an intersection to form a resinoid frame, and a large number of plastic thin threads, running in an outer circumferential axis, are fushion-welded to form a netform cylindrical frame.
CONSTITUTION: A very thick thread, made of a toughened plastic resin, such as high density polyethylene, is used as right selan threads 11 and left selan threads 12, of which a net cylindrical frame consists. In the example, the inner right selan threads 11 and the outer left selan threads 12 are alternately placed at every 3- thread intervals, and overlapped intersections are fusion-welded. A large number of thin plastic resin threads 2 are fushion-welded at an outer circumference of a netform cylindrical frame 1 so formed to finish forming of a culvert drain pipe, and as a result, at least 1,000kg or more of a flatness strength per 1m2 can be obtained.
