Here's how it works and what you need to ensure:
🔧 How Wet Shotcrete Machine Works for High Slope
Concrete Mix Preparation:
A wet mix (pre-mixed concrete with water) is pumped through a hose to the nozzle.
Accelerator may be added at the nozzle to enhance setting time for vertical/hanging surfaces.
Pumping & Spraying:
The concrete is pumped continuously to the nozzle.
High-pressure air assists in spraying the mix onto the slope surface.
The nozzle operator controls spray direction, thickness, and distance.
Robotic Arm or Manual Nozzle Control:
For high or steep slopes, robotic arms or telescopic manipulators are used for reach and stability.
In manual setups, scaffolding, platforms, or manlifts are required for access.
Layer-by-Layer Spraying:
Spraying is done in layers, usually from bottom to top to ensure support.
This reduces rebound and ensures material sticks properly.
Anchoring and Mesh:
Steel mesh or rock bolts are often pre-installed to help shotcrete grip and stabilize the slope.
Shotcrete is sprayed over this for reinforcement.
