探析深孔台阶控制爆破在路基开挖中的运用

Exploring Application of Deep Hole Step Controlled Blasting in Subgrade Excavation

经济的快速发展对工程建设提出了更高要求,路基施工作为工程中不可或缺的一部分,开挖质量将直接影响路基边坡的稳定性及周边安全性,因此,在路基开挖阶段应当对所处区域的岩石分类进行精准把控,选择适配的开挖技术。但是如果岩石分类等级较高,仅利用机械设备对其进行开挖,不仅会导致开挖效果大幅度下降,更会延缓施工进度,直接导致施工成本增加,基于此,应用深孔台阶控制爆破技术也就显得至关重要,就对如何应用该技术进行了细化阐述及分析。

The rapid development of economy puts forward higher requirements for engineering construction. Sub grade construction is an indispensable part of the project.Excavation quality will directly affect the stability of the subgrade slope and the surrounding safety. Therefore, excavation in subgrade The stage should accurately control the rock classification in the area and select the appropriate excavation technique. However, if the rock classification level is high, only excavating it with mechanical equipment will not only lead to a significant decrease in the excavation effect,but also delay the construction progress and directly lead to an increase in construction costs. Based on this,the application of deep hole step control blasting technology. It is also crucial to elaborate and analyze how to apply the technology.
