초록

국내 발파해체기술은 저층위주로 개발, 적용되어 왔으며 1970년대 이후 건축된 고층 RC 라멘조의 내구연한으로 재건축이 필연적으로 예상돼 경제적이고 안전하며 친환경적인 발파해체기술의 개발이 요구되었다. 이에 따라 저층구조물에 적용되었던 발파해체 요소기술을 고층구조물에서 활용할 수 있도록 적용시험을 수행하였다. 고층구조물 발파해체를 위한 요소기술의 정립과 현장 적용성 여부를 판단하고, 문제점 발생 시 개선방안을 제안 해 고층건물에 대한 발파해체 기술을 개발하고자 대전 중앙데파트 발파해체현장에서 방호방법의 현장검증시험과 분진저감을 위한 물대포 현장 적용시험 및 최적천공방법 선정을 위한 요소시험을 수행해 발파해체 요소기술의 신뢰성 확보와 적용성을 확인하였다. 본 논문은 고층건물 철거 시 친환경적이고 안전하며 경제적인 발파해체 공법을 국내 기술로 시공할 수 있는 능력을 알려 외국 철거업체의 국내 철거시장진입을 방지하고 국내 해체산업의 경쟁력 제고에 이바지하고자 한다.

Domestic explosive demolition techniques have been developed and applied for low-rise structures up to now. However, the demand for the development of those techniques that can be applied economically, safely and environment-friendly rapidly increases because the old high-rise RC rahmen structures that were built since around 1970s are now required to rebuild. As a result, element technologies of explosive demolition for low-rise structures were applied to take advantage of technology in high-rise structures that performed application testing at Chungang Department demolition field in Daejeon city. It could judge elements technology establishment for high-rise structure demolition and field application and suggest the improvements when the problems occurred to develop High-rise building demolition techniques for method of protection a field test and the dust reduction test. The water cannon test was applied to reduce the dust site and the drilling tests are performed to select the best components for explosives demolition elements techniques of the reliability. This paper shows that we have the ability to remove a high-rise building using environmentally friendly safe and economical explosives demolition method. It would contribute to prevent a foreign company from entering the domestic market and should contribute to acquire competitiveness of domestic demolition industry.
