Abstract

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.

국내의 소음 진동규제는 점점 더 강화되고 있어 도심지 근접시공을 위해 현재의 저소음 저진동 공법보다 더욱 환경친화적인 공법이 필요하게 되었다. 이 연구에서는 무소음 무진동 공법을 위한 스크류콘크리트말뚝공법의 특징에 대하여 설명하였으며 국내 특정 현장에서 시험시공을 실시하고 말뚝재하시험을 실시하여 시공방법에 따른 연직하중 지지능력을 연구하였다. 선행굴착방식으로 시공된 스크류콘크리트말뚝의 연직압축지지력이 선단분출형슈방식으로 시공된 스크류콘크리트말뚝의 그것보다 70% 이상 크게 나타났다.
