Casing Oscillator Method Cased Drilled Shafts are required when ground conditions are so unstable that drilled holes can not safely be stabilized with drilling slurry or where lose of ground must be controlled. Casing can be temporary or permanent steel pipe which provides a 100% stable excavation for the full length of the drilled shaft. The Casing Oscillator method provides a superior method for drilled shaft construction with high quality ensuring an uninterrupted construction schedule through the elimination of anomalies. This technology is the only proven method to drill large diameter shafts in caving conditions, such as loose sands and gravelly soil with cobbles and boulders. Boulders several feet in diameter can be removed safely by the use of Hammer Grab without major interruption to the excavation process. Since only water is used for drilling, environmental concerns are minimized or totally eliminated using this technique. 4 BUMA CE CO.,LTD.

Casing Oscillator Method 1 2 3 Install starter casing equipped with cutting shoe. Add new casing section with bolted connection. Excavate soil continuously during casing installation. Maintain water head inside casing to balance external hydrostatic head at all times. 4 5 6 Add new casing sections until pile has been excavated to depth. Keep casing tip ahead of excavation at all times. Install reinforcement cage and suspend at proper elevation. Pour concrete using sectional tremie pipe. Maintain concrete head above casing tip at all times. Remove casing and tremie pipe sections simultaneously as concrete is poured. BUILT ON TRUST 5
