Abstract: | In order to smoothly demolish the 14 storey Bingxiong building with frame shear wall structure under the complex environment of Zhengzhou city, a one-way folding demolition blasting scheme was selected based on the actual environmental conditions of the site. Unidirectional folding demolition blasting is to design one blasting cut on the 1-3 floors and the 7-8 floors of the building to be demolished, and to design reasonable blasting parameters. At the same time, the elevator shaft and shear wall are partially predemolished, and digital electronic detonator delay initiation technology is used to ensure the collapse direction and collapse disintegration effect of the building to be demolished. Through the construction of damping dam and excavation of damping ditch, the safety protection of the blasting column in the building, and the establishment of safety protection barriers around, the hazards of blasting vibration, collapse vibration and blasting flying rock are effectively controlled, and the ideal blasting effect is achieved, which can provide reference for similar blasting projects. |
