The present invention relates to a treatment method of contaminated soil at the bottom of a structure using steel pipe indentation, comprising: (S10) a step of monitoring soil in the bottom of a structure; (S20) a step of excavating a side surface of the contaminated soil at the bottom of the structure to install an operation hole; (S30) a step of installing a propelling hole inside the operation hole; (S40) a step of injecting a steel pipe into the operation hole and indenting the steel pipe into the contaminated soil at the bottom of the structure using the propelling hole; (S50) a step of excavating the contaminated soil from the steel pipe; (S60) a step of grouting the outside of the steel pipe; and (S70) a step of filling the inside of the steel pipe with a filler. 본 발명은 구조물 하부 오염토양을 모니터링 하는 단계(S10); 구조물 하부 오염토양의 측면을 굴착하여 작업구를 설치하는 단계(S20); 상기 작업구 내부에 추진구를 설치하는 단계(S30); 강관을 상기 작업구에 투입하여 상기 추진구를 이용하여 구조물 하부 오염토양으로 강관을 압입하는 단계(S40); 강관으로부터 오염토양을 굴착하는 단계(S50); 강관 외부를 그라우팅하는 단계(S60); 강관 내부를 충진제로 메우는 단계(S70);를 포함하는 것을 특징으로 한다.
