The Case Study of Ezplosives Demolition at Chung-Ang Department in Daejeon City
Recently construction techniques have been rapidly developed with reconstruction of old buildings, urban regeneration and efforts of restoring natural ecology, so removal of deteriorated buildings has been rapidly increasing. Removal work of building should be executed without damaging surrounding environments according to relevant regulations,and there are various construction methods for demolition methods and among those, explosives demolition is the most practical demolition method for expenses and safety of work. As a part of Daejeon stream ecological restoration project, this thesis is a case of executing demolition of Chung-Ang Department which was built 35 years ago as covered structure on the upper part of Daejeon stream with explosives demolition. This structure is 8 stories high, total height of 41.6 m including basement floor, 1,650 m2 for building area and 18,351 m2 for total floor area. It is located in the center of Daejeon city where shopping centers and buildings are crowded and main facilities are Daejeon subway (18 m), backside shopping center (20 m), underground shopping center (15 m), Mokchuk bridge, Eunjung bridge(0.25 m) and fiber-optic cable(0.25 m). In this project, implosion was selected for explosives demolition by considering this area being a busy downtown area, and this project was executed after examining collapse movement of structure in advance using simulation program not to damage main facilities. Total 80 kg of blasting powders and 1,000 detonators were being used. This project will be a good case of executing explosives demolition successfully by applying implosion on downtown area in the country.
