In recent years, concrete wet spray trolleys have developed rapidly in China and have gradually become an important equipment in shotcrete construction. Compared with traditional dry spray machines, wet spray trolleys have obvious technical advantages and market demand driving forces, making them more and more widely used.

　　Technical advantages promote the development of wet spray trolleys

　　1. Health and environmental advantages:

　　Wet spray technology significantly reduces the dust concentration during the construction process and reduces the hazards to workers' health. This is especially important in today's construction environment where worker health and environmental protection are of paramount importance.

　　2. Efficient construction:

　　The production efficiency of the concrete wet spraying trolley is much higher than that of the dry spraying machine, which can reach 10 to 30 cubic meters per hour. This efficient production capability greatly increases construction speed and overall project progress.

　　3. Low rebound rate:

　　The rebound rate of wet spraying technology is less than 10%. Compared with the traditional dry spraying process, it greatly reduces material waste and improves construction quality and economic benefits.

　　4. High-quality construction:

　　The water-cement ratio is easy to control during wet spraying, which greatly improves the uniformity and overall quality of the concrete and ensures the consistency of the construction effect.

　　Environmental protection policies and promotion of mechanized construction

　　The country's requirements for environmental protection are becoming increasingly strict, and mechanized construction has become a general trend. It is clearly stated in various design documents and construction specifications that the wet spraying process needs to be used. This is not only the result of policy guidance, but also an inevitable choice to improve construction quality and efficiency.

　　3. Rising labor costs and advantages of mechanization

　　As labor costs rise year by year, the advantages of mechanized operations become more and more obvious. The concrete wet spray trolley can not only more than double the construction efficiency, but also reduce the reliance on highly skilled workers and further reduce construction costs.

　　4. Domestic manufacturers’ R&D and market maturity improvements

　　Domestic concrete wet spray trolley manufacturers continue to improve their research and development capabilities, and their products have gradually matured and achieved standardization and serialization. These advances have significantly increased the market's acceptance and recognition of wet spray trolleys.

　　5. Perfect after-sales service system

　　The comprehensive after-sales service provided by the concrete wet spraying trolley manufacturer provides strong technical support for the operation, use and maintenance of the equipment. This not only ensures the normal operation of the equipment, but also further promotes the widespread application of wet spray trolleys.

　　Wide application and broad prospects

　　Concrete wet spray trolleys are widely used in shotcrete support operations in railway tunnels, highway tunnels, water conservancy culverts, mine tunnels, dam slopes, construction foundation pits and military engineering. As people's awareness of environmental protection increases and the quality requirements for sprayed concrete increase, the market demand for concrete wet spraying trolleys will further expand.

　　Taken together, the concrete wet spraying trolley has developed rapidly due to its advantages such as health and environmental protection, efficient construction, low rebound rate, and high-quality construction, driven by national policies and market demand. In the future, with the further advancement of technology and the continuous expansion of the market, the development prospects of concrete wet spraying trolleys will be even broader.
