控制爆破在泉港分洪闸工程中的运用

Application of the controlled blasting in Quangang Flood Diversion Sluice Project

泉港老闸的钢筋混凝土结构拆除工程采用了控制爆破技术。根据爆区的特殊环境,控制爆破振动及爆破飞石,同时优化爆破参数,解决了新闸底坎二期混凝土浇筑与老闸拆除爆破之间的矛盾。

The removal project of the steel reinforced concrete structures of the old sluice gate in Quangang adopted the controlled blasting technique. Based on local conditions of the blasting area, the blasting vibration and flying stones should be controlled. The blasting parameters should be optimized at the same time. And the contradictions between the pouring of the secondstage concrete on the bottom threshold of the new sluice gate and the blasting removal of the old sluice were solved.
