Title: DEMOLITION OF A 180m HIGH REINFORCED CONCRETE CHIMNEY BY THREE SECTIONS ONE-WAY CONTROLLED BLASTING
Abstract: A 180m high reinforced concrete chimney under complex environment was successfully demolished by three sections one-way graded controlled blasting.The blasting design adopted composite trapeziform blasting cuts to ensure collapse direction of chimney,used loess cushioning and special individual protection measures to effectively control collapse vibration of chimney when it impacted the ground,took rigid and flexible composite protection measures to control blasting flying rock,and chose hanging basket method to construct blasting cut at high altitude.After blasting,collapse direction of chimney was accurate,the buildings and facilities around it were safe.The project obtained good blasting effect and achieved the purpose of safe,precise and rapid blasting demolition.It provides reference for similar project.
