Shotcrete machine, also commonly known as concrete shotcrete machine, is a wet dry concrete spraying equipment specifically used in geotechnical engineering and infrastructure construction. It relies on wind pressure to spray the well proportioned mortar and concrete mixture at high speed onto the working surface, quickly forming a strong support layer. It is widely used in tunnels, slope support, mine tunnels, foundation pit reinforcement, wall plastering and other scenarios.
According to the construction process, Shotcrete machines are divided into two types: dry and wet. The dry shotcrete machine first transports dry materials and mixes them with water at the nozzle. The equipment is lightweight, low-cost, and suitable for small temporary support; Wet shotcrete machines directly transport pre mixed wet concrete, with less dust, lower rebound rate, and higher forming strength. They are the mainstream choice for tunnel and large-scale slope engineering.
The core advantages of the shotcrete machine are outstanding. One of them is high construction efficiency, continuous spraying operation, uniform thickness of single spraying, compared with manual plastering and pouring support, the construction period is greatly shortened; Secondly, the bonding is firm, and high-pressure spraying makes the concrete tightly adhere to the rock wall and wall, making it less prone to hollowing and falling off, and the stability of the supporting structure is strong; The third machine has a wide range of adaptability scenarios, including underground mining tunnels, mountain slope protection, subway tunnels, basement waterproof protection layers, and wall plastering repairs. It can be used for multiple purposes to reduce equipment procurement costs.
The equipment has a low operating threshold and can be put into use with a matching air compressor and feeding pipeline. The Sinovo machine has standardized design for vulnerable parts, and only wear-resistant lining plates, rubber seals, and other vulnerable parts need to be replaced daily, with low maintenance costs. Nowadays, the new mobile spraying machine integrates an electronic control protection device, which has overload power-off and wind pressure adjustment functions, greatly improving construction safety. It is an indispensable core support equipment for infrastructure, mining, and road and bridge engineering.
Overall, the shotcrete machine relies on the spray forming process to simplify the traditional concrete support construction process, while balancing efficiency, quality, and economy. It is the standardized core machinery for modern geotechnical reinforcement engineering.
