人工挖孔桩爆破施工技术

Artificial digging piles blasting construction technology

结合具体工程实例,介绍了人工挖孔桩爆破开挖方案,重点论述了爆破参数的设计,探讨了瞎炮的检查和处理,得出了对于人工挖孔桩等临空面小的爆破工程,采用非电毫秒雷管实现微差爆破效果非常好的结论。

Combined with concrete project example, it introduces the blasting scheme of the artificial digging pile, discusses the blasting parameter design, discusses the check and treatment of misfire, and gets the conclusion that it can get the better effects of using non-electric millisecond detonator split-second delay blasting to the small space blasting project of artificial digging piles and so on.
