  • Because the regulation for a noise and a vibration in our country has been being reinforced more and more, a more environment-friendly pile construction method than a current low-noise and low-vibration method was needed for the close construction in the downtown area. In this study, the characteristics of a screw concrete pile method for noise and vibration-free method was explained, and it's vertical bearing capacity was studied in the base of the static pile load test data of the screw concrete piles. Constructed by two methody; a pre-digging shoe type construction method and a toe-jetting shoe type construction method. The vertical load bearing capacity of a screw pile constructed by the former was more about 70% than that of a screw pile constructed by the latter.
