摘要
为解决传统钻爆法施工隧道时存在机械化程度低、施工人员劳动强度大、施工进度缓慢等问题,文章以宜彝高速公路飞蛾山隧道为工程背景,从施工组织方案、机械化工装作业配套方法、工序施工标准化管理等方面进行分析,提出了一套适用于钻爆法施工隧道的工装配套技术及工序标准化控制方案。实际效果表明:相较于传统钻爆法施工,工装配套快速施工大幅度提升了施工进度,减少了生产成本,降低了施工人员的施工风险;实施工序标准化控制可明显缩短各工序所需时间。通过工装配套设计和工序标准化控制,飞蛾山隧道Ⅳ、Ⅴ级围岩段施工每循环在传统工艺的基础上可分别节约23.85 h和27.5 h,取得了较好的社会效益和经济效益,实现了飞蛾山隧道的快速安全施工。
In order to solve the problems of low mechanization level,high labor intensity and slow construction progress in tunnelling by conventional drilling and blasting method,taking Feieshan tunnel on Yibin-Yiliang expressway as the engineering background,the detailed analysis is carried out from the aspects of construction organization scheme,mechanized equipment operation matching method,construction process standardization management,etc.,and the machinery matching technology and process standardization control scheme are put forward,which are suitable for tunnelling by drilling and blasting method.The actual construction effects show that,compared with the conventional drilling and blasting method,using the machinery matching technology it can greatly improve the construction progress,reduce the production cost and lower the construction risk;and by implementing process standardization control it can significantly shorten the time required for each process.In the construction of GradeⅣand GradeⅤsurrounding rock sections of Feieshan tunnel,by means of machinery matching design and process standardization control it can save 23.85 h and 27.5 h per cycle respectively compared with the traditional construction technology,achieving good social and economic benefits,and realizing the rapid and safe construction of Feieshan tunnel.
