Directional demolition blasting of long,narrow and low urban build-ings
Empirical formulas were used to calculate and analyze the blasting parameters required for blasting demolition of narrow and long-rise buildings.The blasting demolition plan determined the size of the gap between blasting and demolition of buildings with the narrow and long low.carried out targeted control blasting and demolition on-site applications.The directional control blasting and demolition effect was good.The research results show that increasing high explosions can effectively improve the success rate of targeted blasting demolition and demolition of buildings for burst construction,and can greatly increase the efficiency of scum removal;Protective grading settings to improve the protection effect;Explosive shock waves generated by the blasting of narrow and long urban buildings can adopt local reservations,rack protection,temporary fan protection measures to avoid harmful effects of explosive air shock waves;The vibration effect of the pipeline uses the"soft+hard"material protection method to ensure the safety of underground pipeline lines.The research results have good reference significance for targeted blasting construction in similar cities.
