Performance control of root piles using a digital odometer

Root piles are injected and installed during mortar shaft construction, using pressures of up to 500 kPa. The executive control is typically done through static load testing, an expensive time-consuming method. Static tests on eight controlled (diameters between 310 mm 410 mm) were performed, aiming at evaluating pile ultimate load. This study suggests innovative, non-destructive approach validate root field performance, a digital speedometer connected the drilling rig’s rotating head. proposed method monitors variables related bearing capacity installation proposes empirical equation estimate piles. For assessed piles, predictions obtained with equations agreed fairly well results from tests, proving it as feasible helpful option for especially when not available.
