槐扒一级泵站新型防淤进水口的研究

Research on the New-style Anti-deposition Water Intake of Huaiba 1st-stage Pump Station

三门峡槐扒黄河提水工程取水口一级泵站在小浪底上游库区取水。在站前河道出现国内、外同类已建工程所罕见的水位、泥沙淤积变幅及狭窄河道特性的条件下 ,通过对多泥沙河道上岸边固定式泵站进水口型式的研究 ,设计创造性的采用新型竖向流道式防淤进水口的设计方案 ,使这一工程难题得到较好解决 。

The water is lifted from the upstream area of Xiaolangdi reservoir by 1st-stage pump station of water intake at Sanmenxia Huaiba. The unusual water level,severe deposition, and narrow stream characteristics have been observed, which are seldom met in the similar domestic & overseas projects. After the research on the style of water intake of bank stationary pump station along the stream with heavy silt-carrying flow, a creative design plan, the new-style vertical-sprue anti-deposition water intake, is adopted. This design has well solved the engineering problems and brought a good economic efficiency.
