To provide a concrete spraying method that can easily and economically form a sprayed concrete layer with stable quality and high compression strength.SOLUTION: A concrete spraying method of the present invention is characterized by including: a mixing step S1 for generating a sprayed material 10 by adding mixing water 13 to cement 11 and aggregate 12 and mixing them; a force-feed step S2 for force-feeding the sprayed material 10 from a spraying device to a nozzle side; a water addition step S3 for putting additional water 20 in the sprayed material 10 in the nozzle or force-feed hose of the spraying device; and a straying step S4 for spraying the sprayed material 10 onto a construction surface.SELECTED DRAWING: Figure 1
【課題】安定した品質と高い圧縮強度を備えた吹付コンクリート層を簡易かつ経済的に形成可能なコンクリート吹付工法を提供すること。【解決手段】本発明のコンクリートの吹付工法は、セメント１１及び骨材１２に混練水１３を添加して混練し吹付材１０を生成する混練工程Ｓ１と、吹付材１０を吹付装置からノズル側へ圧送する圧送工程Ｓ２と、吹付装置のノズル内又は圧送ホース内において吹付材１０に添加水２０を加水する加水工程Ｓ３と、吹付材１０を施工面に吹き付ける吹付工程Ｓ４と、を備えることを特徴とする。【選択図】図１
