窄缝消能工是国外近廿多年来开始采用的一种新型消能结构,国内近几年才开始研究,我国已兴建此种消能工的工程有东江、龙羊峡水电站及我区二道河子水库。窄缝消能工的特点是:从陡坡段开始断面宽度逐渐收缩入窄缝段,在出口处形成窄而高的矩形断面,迫使水流在挑坎上收缩,挑出后沿水平和垂直方面扩散在空中充分掺
Narrow slit dissipator is a new type of energy dissipation structure adopted by foreign countries for nearly 20 years. Only in recent years has China started to study this type of energy dissipater. There are Dongjiang and Longyangxia hydropower stations in our country, Dahezi Reservoir. Narrow slit dissipator is characterized by: starting from the steep section of the section width gradually shrink into the narrow section, the exit of the formation of narrow and high rectangular cross-section, forcing the water flow in the retractable contraction, pick out the back and forth along the horizontal and vertical proliferation Fully mixed in the air
