At present, there are two kinds of popular shotcrete machines on the market, dry spraying and wet spraying, this kind of equipment started relatively late in China, and some of the scope of application that you may know about it is tunnels, buildings, slope protection, etc. In fact, there are more than that, and this type of equipment is needed in many places. Let's talk about some of the places he can use and how to choose the equipment in the corresponding construction.
1. Construction of coal mines, metal and non-metal mines and tunnels with gas. In this type of project, we generally choose mining spraying machine. Among them, coal mines, metal and non-metal mine tunnels have a small amount of spraying, low spraying height and long spraying distance.
Second, the application in tunnel engineering. The typical characteristics of tunnel spraying are large construction sections and large amount of spraying. Generally, the spraying distance is relatively short and the height is low, and a large amount of spraying machine should be used for spraying construction. However, with the continuous development of technology, tunnel anchor spraying vehicles are basically used for large-scale tunnel projects.
Third, the construction of building foundation pit with a spraying machine The amount of spraying in the building foundation pit is small, the spraying distance is long, and the height is low, and the spraying distance should be selected for the spraying construction of a small square spraying machine with a relatively long distance.
Fourth, slope protection with spraying machine slope protection support spraying distance is long, the slope is high, part of the site has no mixing station, spraying construction can be selected with small amount, long spraying distance, high height shotcrete. Specifically, a spraying machine with automatic mixing and feeding function can be selected.
