<p>PROBLEM TO BE SOLVED: To provide an underground buried pipe execution method whereby shortening of a time for arranging an underground buried pipe can be attained. SOLUTION: In this execution method, a plurality of cable arranging underground buried pipes 1 having a female type joint 4 capable of being connected by providing a male-type joint 3 in one end and fitted to a male type joint 3 in the other end are previously integrally formed by support members 2..., this integrally formed underground buried pipe unit U is arranged along an arranging route. Of the arranged underground buried pipe unit U, between the specific fellow two underground buried pipe units U, U, a pair of bell mouth blocks 9 comprising a cylinder body 12 having a bell mouth part 10 in one end and a concrete-made block part 13 covering this cylinder body 12 are arranged in a condition with the bell mouth part 10 mutually facing the inside, the fellow underground buried pipes 1, 1 adjacent to each other in a longitudinal direction are connected by fitting by both the joints 3, 4. Each bell mouth block 9 and the joint 3 of the corresponding underground buried pipe unit are connected, in the periphery of the bell mouth block 9, by providing a wall body 20, a connection part 8 of hand hole, manhole, etc., is constituted.</p> |
