- 橋梁基礎などの水中構造物の外周を囲撓する仮締切工を備え、前記仮締切工の内部を排水して、前記水中構造物の修理,補強などの改修を行う際に用いる仮締切構造体において、
前記仮締切工は、前記水中構造物の外周を囲繞する複数の環状組立体と、前記水中構造物の基礎部分に立設され、前記複数の環状組立体間を上下に貫通するように設置されて、緊張力を導入して、最上段の前記環状組立体に定着されるアンカーとを有し、
前記環状組立体は、所定高さの環状体を周方向に沿って、複数に分割したプレキャストパネルユニットを周方向の端部間に縦シール材を介装して、相互に連結したものであり、
上下方向に積層される前記環状組立体の上下接合面には、横シール材を介装するとともに、相互に嵌合する嵌合部を設けた仮締切構造体であって、
前記プレキャストパネルユニットは、周方向に連結された状態で外周面を隔成するスキンプレートと、
前記スキンプレートの内面に垂設固定された複数の縦梁と、
前記プレキャストパネルの上下方向の内面に固設され、連結状態で環状に形成される上および下横梁とを有し、
前記横梁の上,下面に設けた前記嵌合部は、凹凸嵌合構造であり、前記凹凸部が嵌合して、相互に当接した際に、前記横シール材を挟圧してシール性を確保しつつ、それ以上の挟圧を阻止して圧壊を防止するクリアランスを設けたことを特徴とする仮締切構造体。
