To provide a spray method and a spray device which can provide spray application with high strength development at an initial stage.SOLUTION: In a spray method to perform spraying to a target object after adding and mixing a set accelerating agent in a base concrete containing cement, a set accelerating aid including gypsums is added to the base concrete before adding the set accelerating agent. A spray device 10 has a force feed pipe 1 for forcibly feeding the base concrete containing cement, an air supply section 2 and a set accelerating agent supply section 3 which are sequentially disposed in a force feeding direction on a side portion of the force feed pipe 1, and a spray nozzle 4 at a terminal portion of the force feed pipe 1. The spray device has at least one set accelerating aid adding section 5 for adding the set accelerating aid including gypsums on a side portion of the air supply section 2 and/or a side portion of the force feed pipe 1 between the air supply section 2 and the set accelerating agent supply section 3.SELECTED DRAWING: Figure 1
【課題】初期の強度発現性が高い吹付施工ができる吹付工法及び吹付装置の提供。【解決手段】セメントを含むベースコンクリートに急結材料を添加・混合した後、施工対象物に吹付けを行う吹付工法において、前記急結材料の添加の前に、ベースコンクリートに対し石膏類を含む急結助剤を添加する吹付工法、並びに、セメントを含むベースコンクリートを圧送するための圧送管1と、該圧送管1の側部に、圧送方向に対して順に配置された、空気供給部2及び急結材料を供給するための急結材料供給部3と、該圧送管1の末端部に、吹付ノズル4を備える吹付装置10であって、前記空気供給部2の側部、及び／又は前記空気供給部2と前記急結材料供給部3との間における前記圧送管1の側部に、石膏類を含む急結助剤を添加するための急結助剤添加部5を少なくとも一つ備える、吹付装置。【選択図】図１
