- 更生管の管端を封止するために用いられる管端封止装置であって、
円柱状に形成され、前記管端に挿入される栓部材、および
前記栓部材を前記管端に挿入した状態で当該管端を前記更生管の外面側から締め付ける締め付け部材を備え、
前記締め付け部材は、
前記更生管を周回して端部がそれぞれ上方に向けて延びる線部材、
前記線部材の各端部を通す2つの開口を有する押さえ部材、および
前記開口を通って前記押さえ部材の上側に突き出した前記線部材の各端部を上方に引き上げる引き上げ手段を含み、さらに
前記栓部材の外周面に形成された凹部および前記凹部の底面に設けられたシール材を備え、
前記締め付け部材によって前記更生管の管端を締めつけたとき、前記更生管の内面が前記シール材に接触する、更生管の管端封止装置。 - 前記締め付け部材は、前記押さえ部材の下面において前記更生管に沿うように湾曲した下板を含み、前記下板には前記線部材の位置決めを行うための1対の保持部が前記押え部材の奥行き方向に所定間隔を隔てて形成され、
前記線部材は、一方の保持部と他方の保持部との間において、前記更生管の管頂から両側に沿って管底で交差し、そこから端部がそれぞれ上方に向けて延びる、請求項1記載の更生管の管端封止装置。 - 前記1対の保持部は前記下板から下方に突出し、その突出寸法は前記線部材の線径よりも小さい所定値に設定される、請求項2記載の更生管の管端封止装置。
