Shotcrete technology
Shotcrete process is to use compressed air to convey the pre-dampened mix through delivery hose to the nozzle to project the material onto the sprayed surface under high velocity, and then to form concrete support layer after the projected material coagulates and hardens. In recent years, with simple technology, special effect, economical cost, flexibility and high construction efficiency, shotcrete technology has been widely applied in construction, railway and super highway engineering, underground engineering, tunneling, mining operations, hydropower projects and slope stabilization, etc. and showing prosperous future. There are two shotcrete ways: dry mix shotcrete and wet mix shotcrete.
Applications
1. Shotcreting for tunnels, hydro-power engineering, mines, underground engineering, civil engineering and slope stabilization, etc.
2. Artificial soil seeding for no soil surface, such as rock, sand, and for no fertility soil surface.
3. Refractory spraying and repair for industrial kilns or kilns' inner liner.
Features:
1. Non-adhesion going-through rotor with new material chamber, completely eliminate bonding and blocking during operation so as to reduce clearance and maintenance period.
2. Thin follow conveying method with vortex flow, so the spraying flow is even, continuous and steady, to improve the shotcrete quality.
3. Four-point clamping device make it easy to adjust the press between sealing plate and rotor disk so as to no air and dust leak and prolong consumption parts life.
4. Particularly used for dry, damp mix and steel (polymer) fibre reinforced shotcrete.
5. Three drive models: By Electric motor, air motor or diesel engine.
