Application of cutting blasting prototyping technology on pier demolition of intake sluice
In view of the partial blasting demolition condition of the piers of a flood gate somewhere,designers decide to use block-cutting presplitting blasting technology to blast the piers according to theoretical calculation and field actual conditions.The designers calculate and optimize blasting parameters,and check the harmful effects of the blasting.After blasting,piers are completely cut off along the cutting line,and the contour of the cutting surface is flat,without obvious over or under excavation.It ensures the stability of the retained piers,moreover,effectively controls the harmful effects of the blasting.
