摘要
深圳市深云村经济适用房基坑底部开挖,遇有特坚硬岩石,需爆0.4~0.8m厚一层石方。在爆破设计和施工中,采用了多装药、同时爆、重填塞、强防护的技术措施,圆满完成了对其的控制爆破,经验可供类似工程参考。
During the process of excavating the foundation pit of affordable housing in the Shenyu village Shenzhen city,especially hard rocks in its bottom were encountered.Especially hard rocks were 0.4~0.8m thick and need be excavated by blasting.Many technical measures which were charging,blasting at the same time,adding length of stemming,and strengthening protection were adopted in design and construction of blasting.The especially hard rocks were excavated successfully by controlled blasting,which provided experiences for similar project.
