Controlled demolition blasting technology for thin reinforced concrete wall of a flood discharging tunnel

根据拆除工程特点,进行方案比较,选择光面爆破方案为最终拆除方案,爆破实践证明:光面爆破方案效果很好,保留面炮孔半孔率近100%,保留砼无损伤。

According to the characteristics of demolition project, smooth blasting is chosen as the final demolition method after scheme comparison. Blasting practice revealed that the effect of smooth blasting was very good,That the half-hole rate of blasting on remained face was near 100%, and remained concrete not damaged.
