摘要
南水北调工程施工标段S44标西市隧洞进口段石方开挖区与当地居民住房毗邻,施工环境复杂,其石方开挖工程量30余万方,工期紧,任务重。在此情况下,采用了适宜的施工爆破技术——以浅孔、深孔控制爆破为主,采用预裂爆破减震措施,边坡光面爆破方案,收到了良好的效果。同时采取了必要的安全防护措施,减小了对居民正常生活的扰乱,为工程顺利实施创造了条件。
Rock excavation in the construction of S44 section of the project was near a residential area, we met a complicated work surrounding. Applied short-hole and long-hole blasting and taken pre-split blasting for damping measures, side slope smooth blasting scheme, we have gotten good results for reducing to disturb people＇s normal life.
