METHOD AND DEVICE FOR CLOSING COLLECTING SEWER
PROBLEM TO BE SOLVED: To provide a device for closing a collecting sewer excellent in workability.SOLUTION: A diameter enlargement implement 19 comprises a cylindrical body 21, and a pair of rubber expansion sleeves 23 and 23 that are provided on both lengthwise-direction sides of the outer periphery of the body 21, respectively. A lengthwise-direction central part of the body 21 is provided with a filler supply hole in advance. Additionally, an injection holder 37 is formed by winding a metal thin-walled plate 41 in a cylindrical roll shape in such a manner that an overlap part 39 is formed. The injection holder 37 is mounted on the outer peripheries of the expansion sleeves 23 and 23 to constitute a closing device.
【課題】作業性に優れた取付管の閉塞装置を提供する。【解決手段】円筒状の本体２１と、この本体２１の外周の長さ方向両側に設けた一対のゴム製の膨張スリーブ２３、２３と、から拡径具１９を構成し、本体２１の長さ方向中央部に充填材供給孔を設けておく。また、オーバーラップ部分３９が形成されるように金属製の薄肉プレート４１を円筒ロール状に巻くことにより注入保持具３７を形成する。注入保持具３７を膨張スリーブ２３、２３の外周に搭載して閉塞装置を構成する。【選択図】図６
