- 外管に内管を挿入して、外管と内管との間に充填材を充填し固化させて二重管を固定する二重管の固定方法であって、
前記内管の位置を複数の仮留め調整手段により調整して仮留めし、前記外管と内管との間に弾性係数が前記充填材とほぼ同じである仮固定材を設置して仮固定し、
前記仮留め調整手段を取り外した後、前記仮固定材を残したまま、前記外管と内管との間に充填材を充填し固化させて二重管を固定する工程を含み、
前記仮固定材は、弾性のある袋に固化材を注入したものであり、
この固化材が注入された前記弾性のある袋を前記外管と内管との間に内管の外側から設置し、固化材が固化した後、前記仮留め調整手段を取り外すことを特徴とする二重管の固定方法。 - 前記固化材としてエポキシ樹脂系硬化材を用いることを特徴とする請求項1に記載の二重管の固定方法。
- 前記仮留め調整手段は、前記内管の内面に取り付けられ、内管の端部から張り出した張出し部を有するボルト受け材と、この張出し部に前記外管に向かって突出可能に設けられたボルトとを備え、
このボルトの先端を前記外管の内面に押し当てて、前記内管を所定の位置に仮留めすることを特徴とする請求項1または2に記載の二重管の固定方法。
