Abstract

PURPOSE:To enable obtaining of a high soil pressure resisting strength irrespective of a less amount of resin used, by a method wherein a thick pipe wall in a triple structure is formed with corrugated threads and fine threads of which a netted cylindrical frame consists. CONSTITUTION:A corrugated thread 11, of which a netted cylindrical frame consists, is of a very thick thread made of rigid synthetic resin such as polypropylen. For example, 8 corrugated threads 11 are alternately arranged at the inside and the outside, all of them stretch in an axial direction as they zigzag in a peripheral direction, and they are mutually fused in a partial manner at a place where crest and trough each corrugated thread are overlapped. A large number of fine threads 2, running in an axial direction, are fused on the outer periphery of the netted cylindrical frame 1, and this permits the formation of a partial tripple structure pipe wall A consisting of the fine threads 2 and the corrugated threads 11 positioned at the inside and the outside of the frame 1.
