中文摘要 | 鯉魚潭水庫士林水力發電工程係配合鯉魚潭水庫第二期工程大安溪導水路工程及 發電工程,經一條長 5525 公尺之壓力式頭水隧道,利用其落差引水發電。為縮短工期,減 低環境影響及提昇國內隧道施工技術, 本工程之頭水隧道採用全斷面隧道鑽掘機 (Tunnel Boring Machine, 簡稱 TBM), 進行隧道開挖及支撐工作。 本 TBM 屬開放型 (Open Main-beam-machine),直徑為 4.53 公尺,長度為 210 公尺, 其最大優點即是可於切削頭 後方及鑽掘進行中安裝隧道所需之支撐材料,避免延誤而引發災變,故被視為適合本工程地 質條件之機型。 本工程頭水隧道 TBM 開挖於民國八十五年五月二日開始鑽掘,迄今進行尚 稱平順,平均進度約 12 公尺 / 日, 若能如期完成,可為台灣隧道工程施工技術開創新的 里程碑。 |
英文摘要 | The project consists of a headrace tunnel about 5,525m in length, an underground power plant about 50m long. A TBM is being employed for driving the headrace tunnel in order to reduce environmental impact during construction and promote tunnel techniques in the local construction industry. The TBM, with a diameter of 4.53m, is of the open main-beam type of Robbins Company, which is considered suitable for the mixed ground at the site. The advantage of TBM is that it enables the installation of rock supporting elements, shotcrete and rock bolts behind the cutter head at a distance of only 3.5m from the face. Rockfall, which is a common problem in the local geology, can therefore be minimized. The TBM was launched from the downstream portal of the tunnel on May 2, 1996, and is advancing moderately at an average rate of 12 meters per day. The experience gained in TBM use will be helpful to the labor-short tunneling industry in Taiwan. |
