Successful completion of test anchor program with 90-0.6" anchors, length 98 m
The Seven Mile project is located on the Pend d’Oreille River in the southeastern part of British Columbia. The project consists of a gravity dam (approx. 70 m high) with power intakes in the present river channel near the right bank and a spillway on the left bank. The four unit powerhouse is located immediately downstream of the power intakes.
BC Hydro planned to improve the dam to reduce dam safety risk.90-0.6" DYWIDAG Restressable Double Corrosion Protected Multistrand Anchors (using micro-wax and extruded PE- sheathing for corrosion protection of strands) with a length of 98 m each were designed, supplied, installed and successfully tensioned.
