Tysim KR90M continuous flight auger piles (CFA) are cast-in-place piles, using a single continuous hollow stemed auger. Vibration free and low noise, this environmentally friendly piling system is ideally suited to installation in unstable soil conditions and urban environments.
KR90M CFA Configuration is a machine dedicated to giving the specialist contractor equipment to perform smaller diameter rotary and CFA piling. It is the result of research and innovation. Continuous Flight Auger (CFA) piles are constructed with partial soil removal, which generates lateral soil compression. As a result the final lateral load bearing capacity is increased and becomes higher than in piles where ben-tonite slurry is used. The level of lateral soil compression depends on the ratio between auger diameter and central stem diameter. The operating process consists in drilling soil with a continuousflight auger welded to a hollow central stem. The bit of the auger drills the soil that is partly pushed upward along the augerflights.
