The wet spraying process can evenly mix water and spraying materials, and the concrete formed by spraying has stable quality and high strength. Wireless remote operation keeps operators away from high dust environments and reduces occupational hazards. In the future, with the continuous strengthening of industrial transformation and environmental protection efforts, as well as the country's promotion of new urbanization, development of the central and western regions, new rural construction and "construction", it is expected to continue to drive the construction of large-scale projects such as municipal, highway, railway, tunnel, water conservancy, and hydropower, creating more market demand for concrete wet spraying trolleys.

The spraying process for the initial support construction of tunnels is constantly updated, and the dry spraying process is transformed into the wet spraying process. The comprehensive cost of wet spraying operations is gradually reduced, environmental pollution is continuously reduced, and the social benefits achieved are continuously improved. Through wet spraying operations, the quality of the initial support of the tunnel can be better guaranteed, making the initial support structure more stable and reliable. The concrete wet spraying trolley is also called a wet spraying manipulator and a spraying manipulator, which integrates the three functions of walking, pumping and spraying. The concrete wet spraying trolley is a large-scale intelligent wet spraying machine, which is widely used in wet spraying concrete operations such as railway, highway tunnels, slopes, water conservancy, hydropower tunnels and culverts, subways and various construction projects.

The wet spraying manipulator is also called a wet spraying trolley or a mechanical arm wet spraying machine. It integrates the three functions of walking, pumping and spraying. It adopts wireless operation to replace manual operation. It has high construction efficiency, fast spraying speed, high degree of mechanization, low rebound rate and high concrete density. It is suitable for various construction environments.
