摘要
沉井井筒内水下开挖岩石技术难度大,既要保护井筒不受损伤,又要达到岩石破碎效果。结合作者所承担的福安市第二自来水厂一号泵房沉井的控制爆破施工,重点论述单响药量的确定和沉井控制爆破的技术参数。该项控制爆破成功的实施,为类似工程提供了宝贵的经验。
It is difficult to dig rock in sinking well due to the requirements of protecting well bore and achieving effective crashing of rock. In the paper, how to determine quantity of explosive of once triggered and how to select controlled blasting parameters are discussed. The engineering was successfully implemented, and it provides an invaluable experience for similar engineerings.
