DIRECTIONAL BLASTING DEMOLITION OF A 11-STOREY FRAME BUILDING UNDER COMPLICATED ENVIRONMENT |
| |
| Abstract: | The scheme and blasting parameters of directional blasting demolition of an illegal 11-storey frame building under complicated environment were introduced.A triangular cut at the bottom of the building was designed,plum-blossom-shape and zigzag-shape hole arrangements were adopted in the columns,each hole was charged with 100g explosive and the delay in holes and out of holes was utilized,which realized delay blasting and directional collapse.The reasons for disintegration of the building in the sky was also analyzed.It has a certain reference for the selection of blasting parameters in similar projects. |
