Concrete Solutions for Tunneling and Mining
Tecwill plants to mix shotcrete (sprayed concrete) and grout for underground construction in tunneling and mining.
TABLE OF CONTENTS
Tecwill shotcrete plant
Tecwill shotcrete solutions create significant savings in tunnel construction and mining operations:
- Homogenous fiber dosing for polypropylene (PP), steel or synthetic fibers
- Better shotcrete quality without fiber clumps, fewer problems with sprayers
- Reduced cement content in a mix design by up to 15%
- Lower CO2 emissions
- Better tunnel lining quality with improved work safety
Why choose Tecwill shotcrete technology?
Fast weighing and fiber dosing control with Tecwill’s “flying” weighing system.
Shotcrete mixing with Tecwill’s innovative on-conveyor fiber feed that reduces mixing time and fiber clumps.
- More accurate weighing
- Less cement
- Correct slump
Multipurpose hybrid plant.
No need for a separate shotcrete plant, as the same unit can mix all mix designs.
The same plant can mix:
- Shotcrete with all types of fibers
- Ready-mix concrete
- Grout mix
- CAF or Backfill, if the necessary equipment is included in delivery
- Precast concrete
Modular construction making the concrete plant fast to install, even in winter, and easy to relocate and reinstall year-round.
Tecwill preassembles the complete concrete plant at its own factory. This includes pre-wiring, piping, thermal insulation enclosure and plant testing.
- Fast set-up time, even in winter
- Easy to relocate and reinstall year-round
- Reliable winter operations
Modules of a Tecwill shotcrete mixing plant
- 1. Aggregate bins
- 2. Mixing unit
- 3. Batch room, admixture storage
- 4. Fiber dosing unit
- 5. Cement silos
Why to choose Tecwill CAF / backfill technology - How Are We Different?
Tecwill’s high-precision “flying” weighing system saves cement and reduces CO2 emissions.
Our “flying” aggregate weighing system eliminates the need to add extra cement to the mix design to compensate for inaccurate weighing and dosing.
- More accurate weighing
- Less cement
- Correct slump
Modular construction makes the plant fast to install, even in winter, and easy and safe to operate.
Tecwill’s approach is to preassemble the complete plant at its own factory. This includes the pre-wiring, piping, thermal insulation enclosure and plant testing.
- Fast set-up time, even in winter
- Easy to relocate and reinstall
year-round - Reliable winter operations
Batch system with a self-learning AI-based
algorithm to control the dosing and weighing.
Self-learning dosing and weighing adjusts the process in real time based on the production parameters. Benefits include:
- High-accuracy material weighing
- The right amount of raw materials in each batch / continuous process
- Less cement
- Reduced CO2
- Shorter mixing time
