摘要(Abstract)：
利用爆破漏斗叠加成槽技术开挖输气管道沟。以底宽 1 6m、深 2 4m的涩宁兰管沟爆破开挖为例 ,介绍了爆破漏斗叠加成槽的基本原理、漏斗试验、爆破参数设计、装药结构和起爆网路。此外 ,简述了爆破施工和安全检算。同时 ,对爆破开挖效果进行了描述和分析。
The superposed blasting cone is used for excavation of a pipe ditch for gas transportation.Taking the blasting excavation of Seninglan pipe ditch with a bottom width of 1.6m and a depth of 2.4m as an example,the principle of trench formation by superposed blasting cone,the tests of blasting cone,the design of blasting parameters,charge structure and priming circuit are introduced.Besides,the blasting construction and safety check are outlined.At the same time,the result of blasting excavation is described and analyzed.
