Tailings dam drainage
Internal drainage is of vital importance to the safety and reliability of tailings dams. The rate at which the tailings consolidate and the sensitivity of the structure to liquefaction depend almost entirely on drainage.
- At the base of the dam as horizontal drainage blanket, DRAINTUBE FTF lowers the phreatic surface
- At regular intervals into the tailings dam, as finger drains, DRAINTUBE FTF helps reduce the pore pressure and controlling the internal erosion
In addition to being cost-effective and easy to install, it has a better impact on the environment as it replaces granular layers and reduces or eliminates the need to transport these resources.
Connection to the main collector pipe using the Quick Connect system
The Quick Connect system connects the mini-pipes of the DRAINTUBE FTF directly to a main collector pipe. This allows for the replacement of the collector trenches when site conditions make their construction difficult. It also permits to better control the outflow.
Benefits
- High drainage capacity under heavy loads
- Improved collection system and phreatic surface control
- Reduced risk of dike failure and better use of tailings to build stable slopes
- Reduced number of collectors or finger drains needed
- Easy installation with a single product to unroll
- Cost-effective and environmentally friendly solution as it replaces granular layers
