Ситуация
The Lauca Hydro Power Plant is located at the foot of a steep slope. The slope requires stabilization to avoid causing damage to the facilities and equipment.
Rеология
Project site consists of the following types of rock:
- colluvium
- silicified sandstone
- porous sandstone
- sandstone-siltstone transition
- siltstone
- gneiss from moderately fractured to strongly altered
Описание
The following solutions were used for slope protection:
Top of the cliffs and tower shaped structures partially protected with TECCO® System:
- high tensile mesh: TECCO® G65/3
- self-drilling nails: INCO 32 TD
- nail diameter: 32 mm
- nail length: 4.0 m
- nail pattern: 1.4 x 1.4 m
Tower shaped structures partially protected with TECCO® System and SPIDER® System:
- high tensile mesh: TECCO® G65/3
- high tensile net SPIDER S4-230
- tower structure width below 3.0 m: nail pattern 1.4 x 1.4 m
- tower structure width over 3.0 m: nail pattern 3.0 x 1.4 m
At the base of the tower structures:
- high tensile mesh: TECCO® G65/3
- self-drilling nails: INCO 32 TD
- nail diameter: 32 mm
- nail length: 4.0 m
- nail pattern: 5.0 x 5.0 m
Regular area of the slope, between rockfall barrier line and top of the cliffs:
- high tensile mesh: TECCO® G65/3
- self-drilling nails: INCO 32 TD
- nail diameter: 32 mm
- nail length: 4.0 m
- nail pattern: 5.0 x 5.0 m
Below the rockfall barrier, ca. 10 m high zone directly above slope cut:
- high tensile mesh: TECCO® G65/3
- self-drilling nails: INCO 32 TD
- nail diameter: 32 mm
- nail length: 8.0 m
- nail pattern: 2.0 x 2.0 m
Self drilling nails were used due to fractured condition of the rock slope.
Passive rockfall protection barrier:
- rockfall protection barrier RXI-050
- height: 4 m
- length: 600 m in 3 sections of: 180 m / 240 m / 180 m
