TUBULAR STRUCTURE
PROBLEM TO BE SOLVED: To prevent damage to a tubular body by alleviating a sudden change in a stress state near an end surface of a concrete body of the tubular body embedded in the concrete body.SOLUTION: An outer periphery of a tubular body 10 of a tubular structure 1 is covered with a concrete body 3. An annular stress dispersion material 30 is provided on a peripheral surface of the tubular body 10 near an end surface 3e of the concrete body 3. The stress dispersion material 30, which is made of fiber-reinforced plastics, an elastic material 40 and the like, disperses stress generated in the tubular body 10.SELECTED DRAWING: Figure 2
【課題】コンクリート体に埋設された管体におけるコンクリート体の端面付近での応力状態の急変を緩和し、管体の損傷を防止する。【解決手段】管構造１の管体１０の外周にコンクリート体３を被せる。コンクリート体３の端面３ｅ付近における管体１０の周面に環状の応力分散材３０を設ける。応力分散材３０は、繊維強化プラスチックや弾性材４０等によって構成され、管体１０に発生する応力を分散させる。【選択図】図２
