摘要
市区内河床改造工程施工受排洪期以及周围环境的限制,必须缩短爆破工期。本次工程采用大孔径的钻机实施浅孔钻孔爆破,并有效控制了震动和飞石,成功完成了在高度危险环境中的大孔径浅孔一次性控制爆破。
The reconstruction of the riverbed in city district should reduce the time limit, due to the time of draining off floodwater and the limit of surrounding environments. This engineering project used large hole driller to implement drilling blasting, effectively eontrolledthe vibration and flying rocks, and successfully performed large hole in shallow hole once controlled blasting.
