浅谈运营高速公路边坡石方爆破施工方法

运营高速公路上边坡石方爆破是工程建设领域的一个难题,常规爆破必然危及高速公路自身结构安全和行车安全。文章介绍了石方普通爆破、孔外延时孔间微差定向松动爆破、劈裂机静态爆破三种不同的爆破方式,并针对运营高速公路实际,提出结合运用孔外延迟孔间微差定向松动爆破和劈裂机静态爆破两种爆破方法,能有效地对运营中的高速公路上边坡石方进行安全爆破。

Discussions on the Slope Stonework Blasting Construction Methods of Operational Expressway

Slope stonework blasting of operational expressway is a difficulty in the engineer-ing construction field, and the conventional blasting will inevitably jeopardize its structure safety and traffic safety of the expressway.The article introduced three different blasting ways of ordinary stonework blasting,directional loosening blasting of time-lapse outside the holes and millisecond between the holes,and splitting-machine static blasting,and regarding the actuality of operational expressway, it proposed that, by using and combining two blasting methods of directional loosening blasting of time-lapse outside the holes and millisecond between the holes,and splitting-machine static blasting, it can effectively carry out the safe blasting for the slope stonework in the expressway under operation.
