Resonant Driving of Sheet Piles: High Production Sheet Pile Driving With Zero Ground Vibration
Matthew Janes, Resonance Technology International Inc., Canada
Sheet piles remain an economic solution to many shoring problems. However, installation of sheet piling suffers high noise and vibration with conventional impact or vibratory methods or low production and high expense with push techniques. Many projects simply will not allow sheet piling due to vibration concerns. Installing sheet piles with a tunable, high frequency Resonant vibrator provides high production with imperceptible ground vibrations. Recent projects in Canada have proven the technique on production projects where vibration sensitive structures are present immediately adjacent to the sheet piling. A project in Whitehorse, Yukon required a Waterloo style impervious sheet pile barrier be driven immediately adjacent to a sensitive, large diameter sewer line. The 1800 m2 Waterloo barrier was driven to prevent hydrocarbon leachate from entering the Yukon River. Proposed driving of the sheet raised concerned as the sewer serviced downtown Whitehorse. Monitoring of the sewer during Resonant driving proved the ground vibrations to be imperceptible. Use of the Resonant Driver prevented all concern over ground borne vibration of the sewer and allowed the contractor to progress at conventional, high production while maintaining low cost to the owner. Subsequent projects continue to prove that Resonant driving of sheet piles achieves high production while eliminating ground vibration.
