Among them, initial support is an important part of tunnel engineering, and shotcrete construction quality control is the key and difficult point of initial support construction. Wet shotcrete refers to mixing cement, coarse and fine aggregates and water in a certain proportion, and then using various types of wet sprayers to transport the mixed concrete to the nozzle through a feed hose, using compressed air to supply energy to form a material bundle, and spraying it from the nozzle onto the sprayed surface.
