To provide a shotcrete machine for ensuring good execution efficiency and, at the same time, ensuring a homogeneous concrete material when spraying work is carried out by means of the concrete material.
The shotcrete machine receives the concrete material through an inlet pipe from a concrete pump. A screw body 14 extending in the direction of the axis is placed inside of the machine body, and the screw body is driven by a motor 13. A first air supply section 15 for supplying an air is provided at least to the machine body, the concrete material is crushed by the screw body, and it is mixed while conveying it to the direction of a nozzle body by the air supplied from the first air supply section. The concrete material well remixed from a nozzle section 11 for the machine of shotcrete is injected into a spray hose while freely floating it in a spray air. By the constitution, a good spray condition and an air conveying distance can be extended.
