中文摘要 | 明潭抽蓄水力發電工程中,兩條最關鍵之壓力鋼管隧道呈 48 度傾斜,每條全長 約 423m,位於砂岩與粉砂岩地層。由於工期緊迫,開挖方法採國內罕見之道坑爬昇工法, 分上、下傾斜段同時施工,其中以上頗斜段 258.7m 長之開挖,創國內爬昇斜距之施工紀錄 ,此亦為榮工處第二度成功應用此工法於不同之地質。 明潭壓力鋼管傾斜隧道之斷面約 57 ㎡,爬昇道坑為 5.8 ㎡。 道坑完成後,由上向下全斷面擴挖,既便於卸碴又無積水之虞。 文中說明爬昇機施工法之施工實例,並探討其使用成效,以供豎坑與斜坑開挖之參考。 |
英文摘要 | Two penstock tunnels of the Mingtan Pumped Storage Project have the length of 423m and the inclination of 48-degree each. Due to the urgent schedule, the pilot tunnels with a cross-sectional area 5.8 ㎡ were excavated by the use of raise climber. The rocks encountered are sandstone and siltstone. The longest length excavated with this method in upper penstock tunnel reached up to 258.7m, with which this agency has made not only a successful construction in different geology for the second time but also a new record in Taiwan. the enlargement of penstock tunnel was then undertaken downwards after completing the pilot tunnel. In this case, mucking was done easily and quickly through the pilot tunnel, and no ground water was accumulated near the excavation face. In this article, the construction method and practical experiences are discribed and discussed. |
