铁路隧道水压光面爆破施工技术

结合工程实例,介绍了在铁路隧道掘进中所采取的水压光面爆破技术,包括炮孔布置、装药量计算及装药结构等。并通过试点,对比分析了同条件下常规光爆与水压光爆的效果及经济效益。水压光爆能提高隧道单循环掘进进尺,改善断面开挖质量,降低掘进爆破粉尘浓度,创造可观的经济效益。

Smooth Hydraulic Blasting Technique in Construction of Railway Tunnel

This article,in the light of an engineering example,mainly introduces hydraulic blasting technique adopted in drilling and blasting with detonator in railway tunneling.Driving under the same conditions,adoption of this technique can markedly improve single-cycle tunneling footage,construction progress and quality of excavation section,reduce excavation blasting dust concentration and creates considerable economic benefits.The results are notable and this technique has high promotional value.
