Abstract

Abstract Translated from Japanese (57)【要約】 【目的】管路の内壁を傷つけることなく、極めて簡単に かつ確実に管路の内周を研磨できる方法及び装置を提供 する。 【構成】マンホール２等の立坑から管路３内にホース１ ３により高圧水を導入し、このホース１３の先端を研磨 機本体４の水圧モータ６につなぎ、この水圧モータ６の 先端に設けた回転体７の先端面に多数の研磨用チップ８ を設け、上記高圧水を上記研磨機本体４の後部から管路 ３の内周後方に噴射させるとともに回転体７の外周から 当該回転体７の外周の略接線方向に高圧水を噴射させ、 当該回転体７を回転させながら上記研磨機本体４を管路 ３内を推進させ、さらに推進中に当該回転体７の外周か ら高圧水を噴射させて管路３の内周壁に当てる。 (57) [Abstract] [PROBLEMS] To provide a method and a device capable of polishing the inner circumference of a conduit very easily and reliably without damaging the inner wall of the conduit. [Structure] From a vertical shaft such as a manhole 2 to a hose 1 in a pipeline 3. 3, high pressure water is introduced, the tip of the hose 13 is connected to the hydraulic motor 6 of the polishing machine body 4, and a large number of polishing chips 8 are attached to the tip surface of the rotating body 7 provided at the tip of the hydraulic motor 6. Is provided, and the high-pressure water is jetted from the rear portion of the polishing machine main body 4 to the rear of the inner circumference of the conduit 3, and the high-pressure water is jetted from the outer circumference of the rotating body 7 in a substantially tangential direction of the outer circumference of the rotating body 7. While the rotating body 7 is being rotated, the polishing machine main body 4 is propelled in the pipe line 3, and during the propulsion, high-pressure water is jetted from the outer periphery of the rotating body 7 and applied to the inner peripheral wall of the pipe line 3.
