The present invention relates to a dam concrete placing method and apparatus, and more particularly, to facilitate the finishing work of one side of the slope of the dam constructed by intercepting mountain valleys or large waterways, and selectively moved from the upper wall of the dam It is possible to lift the slip foam along a pair of side foam rails installed to maintain a predetermined distance on the inclined surface of the order wall by attaching a wire drum for traction to the installed main body, and the concrete supplied from the ready-mixed concrete through the guide chute. Agitation part uniformly coalesced by a predetermined width, the agitating part of stirring the concrete to reach the slip foam located at a far distance of the lower slope through the guide chute provided on the inclined surface of the order wall to stir evenly; Concrete stirred in the stirring section in the stirring section The scraper is separated from the conveyor partially by a connection between the mobile conveyor installed in the width direction of the inclined surface for placing the steel and the concrete conveyed by the mobile conveyor while moving slowly in the same direction while being close to the moving conveyor. And a wire which is wound around the wire drum in the width direction of the wire drum to prevent the meandering phenomenon during the ascending operation of the moving distribution unit in which the distribution chute is integrally installed and the slip distribution for pouring the concrete distributed by the moving distribution unit. It is evenly wound by the guide part operated by the driving of the installed screw shaft.
