【摘要】 介绍了五台县唐家湾水库跃进二渠延伸工程中采用的管道急流输水及W型、撞击、筛网、多级孔板等消能形式的实际运行情况。管道急流输水形式特别适用于土石山区地形复杂、落差大的环境,比传统渠道输水方案节约工程量30.3%,节约投资13.6%,节水8%。W型等4种消能工,消能效果在70%～95%之间,工程量节省30%～85%以上。以上几种新发展起来的消能形式比旧式消能工有无法比拟的优越性。由于整个工程采用了新型结构,节约投资35万元。更多还原

【Abstract】 This paper introduces the actual operation situation of swift hydraulic pipeline and several energy dissipaters in the extended engineering of Tangjiawan Reservoir of Wutai County. The swift hydraulic pipeline, which is applicable in the earth-rock mountain areas with complicated landforms and large drop, can save the quantities of 30.3 %, the investment of 13.6 %and the water of 8 %compared with the traditional channel hydraulic pipeline; And the result of the four kinds of energy dissipaters mentioned in this paper is between 70 %and 95 %, they can save the quantities of 30 %to 85 %and the investment of 35 yuan.更多还原
