FIELD: construction.;SUBSTANCE: invention relates to mixing nozzle for shotcrete application device for dry concrete spraying, to such shotcrete application device and to shotcrete application method. Technical result is achieved by that device for application of shotcrete to apply on surface of sprayed material comprises compressed air source for air supply, reservoir for injector material, filled with dry or liquid injector material, in particular injector fluid containing at least one additive for concrete, dry mixture storage tank filled with dry mixture, without binder and without setting agent, mixing nozzle for mixing injector material with conveying air and dry mixture, pre-wetted mixture of material, spraying nozzle for spraying the sprayed material onto the surface to be coated, tube bundle connected to the mixing nozzle, a liquid container filled with a binder, means for mixing a mixture of materials with a liquid coupling substance to form a spray mass at an end of the hose line before fitting or in the nozzle, in which the shotcrete application device has an air supply line connected to the compressed air source and the injector material supply line, connected to injector material reservoir through injector material supply pump, where lines are connected to mixing nozzle and corresponding material or air is supplied into mixing attachment, at that device for application of shotcrete has second line of air supply, which is connected to the compressed air source, as well as to the dry mixture storage tank and which supplies the transporting air to the dry mixture storage tank for the dry mixture unloading from the dry mixture storage tank, technical result is achieved by a method of dry spraying using such a device, as well as technical result is achieved by a mixing nozzle for this device.;EFFECT: technical result is creation of device for application of shotcrete by dry spraying, at which physical properties of applied concrete should be easily and quickly adapted and optimized.;14 cl, 15 dwg
