雪龙滩水电站引水隧洞总长为2180为,洞型为圆形,隧洞施工区在海拔2550米的高寒地区。隧洞施工采用钻爆法,根据不同的地质情况不断变化调整爆破参数,以取得良好的爆破效果。隧洞支护有钢支撑悬臂棚架超前支护法、钢拱架支护法。为了改善洞内施工环境,采取送、拌组合方式通风。本文就上述施工方法和技术的先进性与效果加以介绍和论述。
The total length of the diversion tunnel of Xuelongtan Hydropower Station is 2180, with a round hole shape. The tunnel construction area is in the alpine area at 2,550 meters above sea level. Drilling and blasting tunnel construction method, according to different geological conditions to adjust the blasting parameters, in order to obtain a good blasting effect. Tunnel support with steel support cantilever scaffold advanced support method, steel arch support. In order to improve the construction environment within the cave, take to send, mix the combination of ventilation. This article describes and discusses the advanced nature and effect of the above construction methods and technologies.
