Situation de départ
Located in an old quarry, the Bakio wastewater treatment plant is surrounded by irregular, 50 meters high slopes. In the past, triple-twist mesh and bolts were installed as a stabilisation system. Due to the proximity of the sea, the system was damaged by corrosion. Also, the stabilization proved to be insufficient: Blocks of up to 30 tonnes came down - a constant threat for the workers.
Géologie
Limestone
Description
The customer opted for a stabilization system with stainless steel mesh consisting of TECCO® STAINLESS G65/3, horizontal reinforcing wire ropes, and GEWI bars of 32 mm in diameter, 8 meters long, with 3Vx4H drilling pattern.
A dynamic rockfall barrier GBE-1000A (1,000 kJ), 4 m high and 110 m long, was installed to protect the WWTP facilities during the stabilization works.
