DAM CORRIDOR CONSTRUCTION METHOD
PROBLEM TO BE SOLVED: To provide a technique for further improving concrete charge property into a bottom face lower part of a corridor cell.SOLUTION: A dam corridor construction method comprises: a cradle installation process for installing a cradle on which a precast corridor cell which is a corridor cell of a dam corridor and has multiple holes formed on its bottom face, is laid on a levee body concrete of a prior lift; a corridor cell installation process for laying the corridor cell on the cradle; and a concrete placement process for embedding the corridor cell by placing concrete in a cavity in a bottom face lower part of the corridor cell laid on the cradle, the periphery of the bottom face lower part of the corridor cell and the periphery of the corridor cell. In the concrete placement process, the concrete is placed in the cavity in the bottom face lower part of the corridor cell while checking a charging state from the multiple holes.SELECTED DRAWING: Figure 7
【課題】通廊セルの底面下方へのコンクリートの充填性を更に向上する技術を提供する。【解決手段】前リフトの堤体コンクリート上に、前記ダム通廊の通廊セルであって、底面に複数の孔が形成されたプレキャストの通廊セルが載置される架台を設置する架台の設置工程と、前記架台上に前記通廊セルを載置する通廊セルの設置工程と、前記架台に載置される通廊セルの底面下方の空隙、通廊セルの底面下方の周囲、及び通廊セルの周囲にコンクリートを打設して前記通廊セルを埋設するコンクリートの打設工程と、を含み、前記コンクリートの打設工程では、前記複数の孔から充填状況を確認しながら、前記通廊セルの底面下方の空隙にコンクリートを打設する。【選択図】図７
