近年来,随着城市的快速发展,在人口、交通密集区域的土石方开挖及混凝土结构物拆除工程日益增多。由于普通机械开挖,冷凿速度较慢。普通爆破对周围环境、人员造成的危险性较大。越来越多的工程中应用浅孔控制爆破进行施工,提高功效,保证安全。本文以贵州省息烽县团圆山环线道路建设项目路基土石方开挖为研究对象,简要分析控制爆破在市政工程中应用,为后期类似工程提供一定的借鉴和参考。
In recent years, with the rapid development of the city, earth excavation and demolition of concrete structures in population and traffic-intensive areas have been increasing. Due to ordinary mechanical excavation, cold chisel slower. Ordinary blasting on the surrounding environment, the greater the danger caused by personnel. More and more projects using shallow hole control blasting construction, improve efficiency, ensure safety. In this paper, the earth and stone excavation of roadbed in TuanYunshan circular road construction in Xifeng County, Guizhou Province is taken as the research object. The application of controlled blasting in municipal engineering is briefly analyzed, which will provide some reference and reference for similar projects in the later period.
