Obstacle deviation structure null of subterranean embedding

摘要

PROBLEM TO BE SOLVED: To arrange an underground embedded tube by causing an obstacle to be easily and rapidly detoured.;SOLUTION: An obstacle detour structure for an underground embedded tube comprises an outside tube for connecting connectors arranged at specified positions and a plurality of inside tubes 4 each arranged in the outside tube, in such a manner that the tubes 4 are each formed of a flexible material. The outside tube is divided into an arranging route upstream side and an arranging route downstream side through an obstacle 1 existing in the route to block openings of the two outside tubes 2, 3, and end caps 5, 6 having a plurality of through-holes for penetrating and supporting the tubes 4 are provided. The tubes 4 are bent and deformed between the cap 5 provided at the end of the tube 2 disposed at the upstream side and the cap 6 provided at the starting end of the tube 3 disposed on the downstream side to detour the obstacle 1.;COPYRIGHT: (C)2000,JPO
