摘要
目前铁路岩石路堑边坡同一级台阶开挖施工爆破常分几次完成,这种施工方法不仅施工效率低、成本高,而且施工质量难以保证。为此,在肯尼亚蒙内铁路DK399+430-DK399+750段路堑边坡开挖爆破施工中采用了一次成型开挖爆破技术,介绍了爆炸方案及参数。工程实践表明,这种爆破技术提高了铁路岩石路堑边坡开挖施工效率和质量,降低了施工成本。
At present,the excavation and blasting of the same stage of the railway rock cutting slope is often divided into several times to complete,which is inefficient,high cost and difficult to guarantee construction quality.Therefore,the one-forming excavation blasting technique is used in the cutting slope excavation blasting construction of Kenya Mombasa port-Nairobi railway DK399＋430~DK399＋750,and the detailed design is given.The engineering practice shows that the blasting technique can improve the efficiency and quality of construction of railway rock cutting slope excavation,and reduce the construction cost.
