Abstract

To provide an integrated submerged caisson body, a method for installing the same, and a method for installing and joining the submerged caisson body.SOLUTION: An integrated submerged caisson body 1 includes a standard submerged caisson body 1, and water cut-off joints 2 that are sealed and annularly extended and contracted are installed on both ends of the standard submerged caisson body 1. The finally joined submerged caisson body is still a standard embedded joint, and accordingly the same base as that of a general joint is used, a rigidity difference does not exist, a risk of non-uniformly settling the joint during an operation period of a submarine tunnel is effectively reduced, and the same installation facility can be used for installation of the finally joined submerged caisson body and installation of the other embedded joint. An installation of one special final joint to a conventional method is reduced without arranging extra facility such as a floating crane, a flow of construction is simplified, and a construction risk can be reduced.SELECTED DRAWING: Figure 1

【課題】一体化沈埋函体、その設置方法及び沈埋函体の設置接合方法を提供する。【解決手段】一体化沈埋函体は標準沈埋函体１を含み、標準沈埋函体１の両端には密閉された環状の伸縮可能な止水継手２が設置されている。最終的に接合した沈埋函体は依然として標準埋設継手であるため、一般的な継手と同じ基盤を使用し、剛性差が存在せず、海底トンネルの運用期間中に継手が不均一に沈降するというリスクを効果的に低減すると共に、最終的に接合する沈埋函体の設置とその他埋設継手の設置には同じ設置設備を使用することができる。起重機船等の設備を余分に配置することなく、従来の方法に対して１つの特製最終継手の設置を低減し、施工のフローを簡略化し、工事リスクを低減することができる。【選択図】図１
