摘要
Raise Boring工法應用在馬鞍水力發電工程中之壓力鋼管路導坑工程,效果良好。此壓力鋼管路,傾角48°,開挖直徑約6.8公尺,垂直高差88.94公尺,導坑鑽掘直徑為1.42公尺,斜深106公尺﹔從起鑽到結束,只是用16個工作天,若依照傳統工法則約需三個月時間。本工法乃使用油壓式大型鑽機取代傳統之鑽炸工法,免除仰賴人工的缺點,故不論在施工效率、安全及費用上,均較其他工法為佳﹔此次施作且為水力工程上之創舉。本篇嘗試詳細介紹其實際施工過程,工法之簡介及實績說明,以及與傳統工法之比較分析。
英文摘要
Raise Boring was applied to make a pilot shaft for the penstock in Maan hydropower project,and was proved to be a successful method. The penstock is 48 degress in inclination, 6.8 meters in excavation diameter, 88.94 meters in depth ﹔its pilot shaft is 1.42 meters in diameter, 106 meters in inclined length. Its operation from beginning to finishing took only 16 working days. According to the similar projects completed, it would be about 3 months spent by the D & B. The Raise Boring method using the hydraulic drill instead of the D & B method, cuts down very much manpower ,and moreover, it is more efficient, safer and economical than others. It is also the first time that a pilot shaft of the hydopower project was completed by using Raise Boring method. This article is to report its actual operation in detail, to brief the method and merits, and to make a comparison with the traditional methods.
