Abstract

본 발명은 말뚝 선단의 기초부 형성과 인장부재의 고정정착부 형성을 위한 시공방법으로서, 지반을 깊이방향으로 천공한 후 천공홀 선단부에 공벽확장용 도구를 위치시키는 단계와, 공벽확장용 도구를 구동시켜서 천공홀 선단부를 확공함과 동시에 상기 공벽확장용 도구로 확공부의 상부 원지반을 받침지지하는 단계와, 기초용이나 고정정착용 콘크리트를 공벽확장용 도구를 통해 통과시켜 확공상태의 천공홀 선단부의 공간에 타설로 채워주는 단계와, 공벽확장용 도구를 점차 축소시킴과 동시에 축소에 따라 생기는 공간에 기초용이나 고정정착용의 콘크리트 타설로 채워주어 최종적으로 말뚝 선단에 확대 기초부를 형성하거나 인장부재의 고정정착부를 형성하는 것이다.
