Tunnel wet spraying manipulator is an indispensable and important equipment in modern tunnel engineering, widely used in shotcrete support construction in railway and highway tunnels, water conservancy and hydropower culverts, underground mines and other fields. Compared with traditional dry spraying equipment, wet spraying robots have significant advantages in construction quality, efficiency, and safety.

　　Improve construction quality and efficiency

　　The wet spraying robot uses wet spraying concrete, which can cover the tunnel wall more evenly than dry spraying equipment, greatly improving the construction quality. The wet spraying method of concrete has better adhesion and flowability during the spraying process, which can ensure the compactness and uniformity of the concrete layer, effectively reducing the occurrence of voids and cracks. In addition, the wet spraying robot has a high degree of automation and simple operation, which can significantly improve construction efficiency and shorten the project cycle.

　　Reduce rebound rate

　　During the spraying process of dry spraying equipment, concrete is prone to rebound, resulting in material waste. The rebound rate of wet spraying robotic arms is relatively low, allowing concrete to better adhere to the construction surface, significantly reducing material waste and lowering construction costs. This not only saves resources, but also enhances the environmental friendliness of construction.

　　reduce labor intensity

　　The use of wet spraying robotic arms greatly reduces the labor intensity of workers. Traditional dry spraying construction requires workers to operate in close proximity for a long time, which not only consumes a lot of physical energy but also faces high risks. The automation operation of the wet spraying robotic arm reduces the direct involvement of workers, who only need to monitor and adjust within a safe distance, greatly reducing physical labor and construction difficulty.

　　Improving the health status of workers

　　The construction environment of tunnels usually has a lot of dust, and dry spraying equipment can generate a large amount of dust, which poses a serious threat to the health of workers. The wet spraying robotic arm effectively reduces the generation of dust, lowers the risk of workers inhaling harmful dust, and significantly improves the air quality at the construction site. This not only ensures the health of workers, but also meets the requirements of modern environmental protection construction.

　　Tunnel wet spraying robotic arm plays an important role in tunnel construction due to its superior performance. By improving construction quality and efficiency, reducing rebound rate, reducing labor intensity, and improving the health status of workers, wet spraying robots not only enhance the safety and economy of construction, but also promote the development of tunnel engineering towards a more environmentally friendly and efficient direction. As the core equipment for tunnel construction, wet spraying robotic arm is undoubtedly an important innovation in modern engineering construction.
