POROUS PIPELINE AND CORRUGATED PIPE USED THEREFOR

摘要

PROBLEM TO BE SOLVED: To provide a porous pipeline uncollapsible in arrangement of pipes and relatively simple in execution work in the porous pipeline constituted by juxtaposing plural corrugated pipes. SOLUTION: The mutually adjacent corrugated pipes 10 are arranged in a state of meshing crest parts 14 and trough parts 12 of a waveform. Recessed parts 16 are formed at 90 deg. intervals on the outer periphery of the crest parts 14 of the respective corrugated pipes 10. The mutually adjacent corrugated pipes 10 are combined so that a part of the outer periphery of the trough parts 12 of the adjacent corrugated pipes 10 enters the recessed parts 16.
