Omega Mine extends AMD treatment capacity with dewatering
At Omega Mine in West Virginia, GEOTUBE® GT500 units help the West Virginia Department of Environmental Protection treat and dewater acid mine drainage from abandoned mines while supporting long-term capacity and compliance.
Dredging and reuse of contaminated sediments
Embraport used dewatered contaminated sediments as structural fill within its terminal platform, saving 400,000 m3 of imported material and reducing earthfill platform costs by 20% to 30%.
MSW incineration and power plant platform, Yuxi City, Yunnan Province, China
A USD 50 million MSW incineration plant in Yuxi City uses reinforced segmental block retaining walls to form platforms in rugged terrain and process up to 1,000 tonnes of waste per day while generating electricity.
The Kanaka Durga temple, located on Indrakiladri Hill along the Krishna River in Vijayawada, Andhra Pradesh, India, is a popular religious site that attracts millions of worshippers annually. However, the existing road, constructed in 1969, was insufficient to handle the increasing heavy traffic. To address this issue, Solmax sought technical assistance and utilized their expertise to find an economical solution for widening the road. After careful analysis, it was determined that a segmental retaining wall using MIRAFI® Polyfelt® PEC was the most suitable option compared to alternatives such as building a bridge or excavating the hill.
The 22 m (72.2 ft) high wall was divided into two tiers: a 12 m (39.4 ft) tier and a 10 m (32.8 ft) tier, with a 5 m (16.4 ft) offset, designed according to BS8006 standards. The top tier was individually designed to accommodate traffic load, while the bottom tier considered both the full surcharge of 10 m (32.8 ft) and the traffic load from the upper tier. Locally available murum soil with a friction angle of 32 degrees was used as backfill material.
For reinforcement, a composite geotextile was employed, consisting of high-strength polyester yarn incorporated into a non-woven continuous fiber geotextile. This geotextile provided both tensile strength and drainage functionality. The tensile strengths of the reinforcement layers ranged from 50 kN/m (286 lb/ft) to 200 kN/m (1,143 lb/ft).
In this project, the high-strength geotextile reinforcement layers were installed at an inclined angle for improved pullout resistance. Additionally, all reinforcement layers were anchored at the far end in a trench that was backfilled with soil for tensioning.
