Blasting Demolition Technology and Vibration Monitoring of Two 90m-high Cooling Towers in Complex Environment
This paper describes the successful experience of the directional control blasting of two 90m-high reinforced concrete cooling towers of Hefei Power Plant in Anhui Province.The blasting is in the complex environment.It emphatically describes the pretreatment measures,blasting cut shape and size,blasting parameters,detonator detonating network and blasting safety technology of the directional window,oriented window and load reducing slot,and the blasting vibration was tested and analyzed,and this paper provides the protection method for opening the special-shape load reducing slot and dense mesh safety net cross-multilayer coverage.Especially,the blast holes for opening the special-shape load reducing slot and the herringbone column are centralized at the bottom and top,which not only reduces the drilling workload,but also reduces the maximum detonating explosive amount of single section,and also reduces the safety protection workload.It can be a reference for similar projects.
