CONSTRUCTION METHOD AND PRECAST MEMBER
To provide a construction method and a precast member capable of making a precast member lightweight and efficiently carrying out a work of constructing a training wall of a dam.SOLUTION: A construction method in one embodiment for constructing a parapet portion 20 formed on a main body 11 of a training wall 10 provided along a water passage of a dam and protruding to the water passage side by a precast member 21, comprises the steps of: installing the precast member 21 on the main body 11 so that a bottom plate portion 22 of the precast member 21 protrudes to the water passage side and a side wall portion 23 of the precast member 21 is erected from a part 22a protruding to the water passage side of the bottom plate portion 22; and installing concrete C on a side opposite to the water passage of the side wall portion 23 and on an upper side of the bottom plate portion 22.SELECTED DRAWING: Figure 6
【課題】プレキャスト部材を軽量化することができると共に、ダムの導流壁を構築する作業を効率よく行うことができる構築方法及びプレキャスト部材を提供する。【解決手段】一実施形態に係る構築方法は、ダムの水路に沿って設けられる導流壁１０の本体１１上に形成されると共に水路側に突出する波返し部２０をプレキャスト部材２１によって構築する構築方法であって、プレキャスト部材２１の底板部２２が水路側に張り出すと共にプレキャスト部材２１の側壁部２３が底板部２２の水路側に張り出した部分２２ａから立設するように、本体１１上にプレキャスト部材２１を設置する工程と、側壁部２３の水路との反対側、及び底板部２２の上側にコンクリートＣを打設する工程と、を備える。【選択図】図６
