Application of Rapid Construction Technology of Integrated Excavation in Large Section Soft Rock Roadway

为在软岩巷道掘进过程中保障综掘施工的整体效率,提升大断面软岩巷道掘进质量,论文结合某综掘项目以及大断面软岩巷道施工难点、综掘前的支护原则,详细论述了大断面软岩巷道中综掘快速施工技术的实施方案,强调在应用大断面软岩巷道综掘快速施工技术时,相关主体只有结合软岩特点,灵活应用综掘设备,计算调整综掘快速施工参数,才能完善支护环节的技术方案,保障巷道综掘施工设计的可靠性,减少大断面软岩巷道掘进时的安全风险。

In order to ensure the overall efficiency of comprehensive excavation construction in the process of soft rock roadway excavation, and improve the quality of large-section soft rock roadway excavation. This paper discusses the implementation of the rapid construction technology scheme in a large section soft rock roadway, combined with the construction difficulty and the construction principle of comprehensive excavation. It emphasizes that when the rapid construction technology of comprehensive excavation in large section soft rock roadway is applied, the relevant subject must combine the characteristics of soft rock, flexibly apply the comprehensive excavation equipment, calculate and adjust the rapid construction parameters of comprehensive excavation. Only in this way can the technical scheme of supporting link be perfected, the reliability of integrated excavation construction design of roadway can be guaranteed,and the safety risk of large section soft rock roadway excavation can be reduced.
