Soil Conditioning Takes a New Form
Encapso™ soil conditioner is a major step-change in the evolution of tunnel boring component delivery and is transforming the way operators fight sticking clays, water incursions and friction - resulting in superior boring efficiency and economics.
Innovative
- Increased advance rate by providing conditioning where it is needed most
- Wear reduction owing to the tribological properties of triglyceride oils
- Plasticizes spoils aiding muck removal
- Improves stability of tunnel face, by reducing water incursion
- Keeps ports open and clean when applied before shutdowns
- Compatibility with slurries and foams due to natural encapsulation
Proven Performance
- Seattle case study: 72% improvement in advance rate - 2X productivity
- Laboratory tests: less cutter wear – fewer interventions – faster progress
Proved benefits through commercial use in a 21-foot diameter tunnel:
- 72% improvement in advance rate after use in just 20 feet
- Made operations smoother by improving consistency of movement
- Improved productivity from 45 feet/day to 90 feet/day
Results
- Improved advance rate
- Improved consistency of movement
- Improved muck condition / consistency
