Would you please tell me the difference between the concrete and shotcrete in the tunnel?
Characteristics of shotcrete:(1) the sprayed concrete has the characteristics of rapid growth, strong bonding force, high density and good impermeability. It can better fill the gap between the rock blocks, increase the integrity of the surrounding rock, prevent the free surface weathering and loosening, and work together with the surrounding rock.(2) the construction of shotcrete will transfer, pouring and tamping a few processes into one, and do not need a template, so the construction of fast, simple.(3) sprayed concrete can play an important role as early as possible.(4) compared with the concrete, the physical and mechanical properties of sprayed concrete are improved.
Jet coagulation: the construction method of spraying fine concrete with spray gun. It is often used to fill the lining of tunnel lining, wall, ceiling and other structures.
These two kinds of concrete construction method is actually the difference.Formwork concrete: after the formwork is good, the concrete is the concrete, such as the tunnel lining, the bridge pier and so on.
