窄缝式消能工是近几年在国内开始研究应用的。它改变了过去在溢洪道消能设计中通常采用的横向扩散、降低单宽流量的设计方法。赤峰是二道河子水库在我区首先将这种消能方式应用于水库溢洪道的改建工程。该项技术的应用,较之等宽挑坎,减少了近10万立米的土石方开挖量(其中石方开挖量8万立方米),从而节省了工程费用。 Slit-type energy dissipater in recent years in China began to study the application. It has changed the design of the laterally diffused, lower single-width flow that was commonly used in spillway energy dissipation designs. Chifeng is Erdahezi Reservoir in my area first of all this energy dissipation method used in the reservoir spillway reconstruction project. The application of this technology has reduced the construction cost by nearly 100000 cubic meters of earth and stone excavation (of which 80,000 cubic meters of stone was excavated) compared with the same width.
