摘要
溪洛渡水电站导流洞工程规模居世界前列,其右岸导流洞闸门竖井开挖断面尺寸大、工期紧张、施工干扰大,充分利用竖井断面大、作业面宽的特点,采用了类似于洞外边坡开挖支护的方法开挖支护施工,使工期提前1.5个月,实现了竖井开挖快速施工.对右岸导流洞闸门竖井的开挖快速施工技术进行的分析和总结,可供其他类似工程借鉴和参考.
The dimensions of diversion tunnel of Xiluodu Hydropower Station takes lead all over the world because the excavation sizes of gate shaft of right diversion tunnel was broad, the construction schedule is urgent and the construction is interfered frequently by outside factors. So, a similar excavation supporting method often used in slope excavation has been applied to excavate diversion tunnel according to the characteristics of broad cross section and wide construction site. As a result, actual construction time is 1.5 months ahead of scheduled time-table; and rapid construction of excavation of shaft is realized as well. Through analyzing and summarizing the actual experiences and skills of rapid excavation construction techniques of gate shaft of right diversion tunnel, some valuable experiences are provided for other similar projects construction.
