Common concrete spraying machines are mainly divided into two categories: dry concrete spraying machines and wet concrete spraying machines. Compared with dry concrete spraying machine, wet concrete spraying machine has low dust concentration, low rebound rate and high strength of sprayed concrete, which greatly saves costs and effectively improves the construction environment.
The concrete pumping wet spraying machine is a hydraulic wet spraying machine, a special wet spraying concrete equipment for spray anchor support. Concrete pumping wet spraying machine is mainly composed of walking system, concrete pumping system, liquid accelerator adding system, lubrication system, air duct system and electrical system.
The working principle of the concrete pumping wet spraying machine is to use the thrust generated by the hydraulic pump to send the commercial concrete from the conveying pipeline to the mixed flow pipe, form a thin stream of compressed air and send it to the sprinkler through the pipeline, and add the liquid accelerator to the sprinkler. , And then sprayed onto the sprayed surface at high speed to quickly condense to form a concrete supporting layer.
The concrete pumping wet spraying machine is simple to operate, has high construction efficiency, long conveying distance, low resilience, and adjustable sprayed concrete conveying volume and quick-setting admixture. The concrete pumping wet spraying machine has multiple functions and can be used for spraying, filling, grouting, pumping and other engineering constructions. It is widely used in railway tunnels, highway tunnels, water conservancy culverts, mine roadways, dam slopes, construction foundation pits and military Wet shotcrete work in construction in engineering and other fields.
