|
| Installation of the MS³
system for slope stabilization begins with construction of a
concrete beam near the ground surface. Angled micropiles, in
a fan array typically composed of three structural elements,
are then drilled in place through the beam and founded in a
competent stratum. |
|
| Several conditions
must exist in order for micropile walls to yield best results: |
- Access must be such that you can
reach the approximate mid-point of the failing slope with
men and equipment.
- The reinforced concrete cap may
be installed before of after drilling and grouting of the
micropiles.
- Some walls may also require tieback
anchors to be installed and stressed against the concrete
cap if landslide forces are enormous.
- Sequencing of pile and tieback installation
is important.
- Walls with rock drilling for micropile
sockets are more expensive than soil only walls.
- Applicable in almost all soil types
up to depths to failure plane of 50 feet.
|
| Inclinometer results
are generally the determining factor to verify that slope movements
have arrested after completion of the system. |
- Little or no excavation is required
- Speed of installation
- Wide applications range
- Effective in a variety of soil conditions
- Environmentally friendly –
walls can be buried and made invisible
- Non-hazardous
- Economic alternative to tieback
walls
- Minimal impact to surface environment
