Abstract

Recently, the demand for demolition of unnecessary steel shell structure is increasing due to deterioration and unsatisfactory functional conditions and the issue of demolition is becoming a major highlight. This execution case was intended to describe an application of the felling method, a explosive demolition method to demolish steel shell structures, for the demolition of a steel stack and steel head tank. As a result of the explosive demolition, the steel stack and steel head tank had collapsed precisely according to the estimated direction. And the explosive demolition was completed without causing any damage to surrounding facilities.

최근 노후화와 기능적 요건을 만족하지 못하여 불용하는 스틸 셸 구조물의 해체 수요가 증가하면서 스틸 셸 구조물 해체에 대한 관심이 부각되고 있다. 본 시공사례는 구조적 노후화와 기능적 요건을 충족하지 못하는 스틸 셸 구조물인 굴뚝과 수조의 해체에 발파해체공법 중 전도공법을 적용하였다. 발파해체 결과, 스틸 굴뚝과 스틸 수조는 예측된 방향으로 정확히 전도되었으며, 주변 시설물에 피해 없이 발파해체를 완료하였다.
