| 摘要 | PURPOSE: To dispense with a job for joint joining work as well as to prevent a leak of water from occurring by bending each of long strip underground pipes consisting of a plastic material successively, joining their side ends together, and inserting each one into a buried hole for propulsion forward as molding an endless underground pipe there. CONSTITUTION: A leading body 10 is pushed forward in the ground from the side of a vertical shaft V, forming an underground pit there, while a propulsion supporter 20 is successively connected to the rear of this leading body 10. At the vertical shaft V, an underground pipe 62 is fed to a guide roll 74 and a cylinder machining unit 76 from two bending rolls 71, 72, forming an endless underground pipe 60. In addition, this pipe 60 is locked to a supporter 20 by an expansion mechanism 50, and then it is pushed forward in an underground hole. COPYRIGHT: (C)1991,JPO&Japio |
