摘要
小断面长隧洞具有断面小、距离长的特点,在施工中存在空间有限、交叉工序多、大型高效机械无法运用等问题,施工难度大,工期紧张.为了克服这些困难,本文结合义乌市横锦水库引水工程实际,从施工组织方案的支洞设置、施工机械、爆破循环优化等方面进行优化,在小断面长隧洞的快速施工中取得了良好的实践效果,并为今后类似工程施工提供一定的指导和借鉴.
A lot of small-long tunnel constructions are encountered many problems, such as limited space, intersected working procedure and inefficient applying of large-scale machine. In order to overcoming these difficulties, the optimization in the construction of branchhole, construction machine applying and demolition circulation are analyzed based on the diversion tunnel excavation of Hengjing Reservoir in Yiwu City and some reasonable data for the similar project constructions are achieved.
