Application

• Tunnel safety support

The spray layer supported by steel fiber shotcrete is more in line with the concept of "flexible support". The steel fiber endows the supporting layer with a certain ductility, which can not only absorb the energy brought by the deformation of the surrounding rock, but also mobilize and stimulate the self-stabilizing ability of the surrounding rock by fitting the surrounding rock.

• Simple and quick construction

The steel fiber shotcrete replaces the hanging net construction, which not only saves the cost of hanging nets, but also reduces the risk of rockfall injury. At the same time, the steel fiber shotcrete can be constructed quickly in the first time, can be closed in time, and quickly stabilize the surrounding rock.

• Smaller rebound and less consumption

The rebound of steel fiber shotcrete is smaller than that of hanging net shotcrete, and the molding of concrete is more compact. And there is no need to backfill the over-excavated part, which greatly saves the consumption of concrete.

Every year, the number of steel fibers we produced that can orbit the earth 230 times.
