概述巴伐利亚水电站股份有限公司(缩写为巴伐克)曾在罗斯豪普吞发电站(1954年竣工)用虹吸管进口作为电站的高水头输水装置,取得了很好的经验。因此人们决定在寿高雷赫河梯级枢纽6~#的输水管隧道的位置装设虹吸管进口,最初仍考虑在隧洞工程上的输水管进口前用钢闸门,又在水轮机前放压力钢管。但是在预留位置的菱铁石基础却要求隧洞有特别的措施。而钢制的压力管道的斜坡切力,以集中荷载通过单独支撑传到不安全的基础上,这些困难必将导致很贵的费用。通过应用虹吸管进口能够节省深的隧洞进口,经过土坝顶上安装一输水管道,这些分节管道是预应力混凝土制成,管道可以在开敞基坑直接埋入菱铁石基础中,因此大部分切力由于摩擦直接由基础承受。
Overview The Bavarian Hydropower Co., Ltd. (abbreviated as “Bavaria”) has gained good experience in importing high-head water-delivery units for power plants using a siphon pipe at the Rose Haupton Power Station (completed in 1954). Therefore, it was decided to install a siphon inlet at the location of the 6 ~ # pipeline tunnel at the Shougao Lehe River Cascade. Initially, the steel gate was used before the inlet of the water inlet pipe in the tunnel project, and the pressure steel pipe was put in front of the turbine. However, the reserve of the barite base requires special measures for the tunnel. The sloping shear of steel pressure pipes, on the other hand, is transmitted to the unsafe base by a single load, which inevitably leads to expensive costs. Through the application of siphon imports can save deep tunnel entrance, through the top of the earth dam installation of a water pipe, the sub-section pipe is made of prestressed concrete, pipe can be embedded in the open pit directly into the basement of the stone, so large Part of the shear force is directly borne by the foundation due to friction.
