Study on Design of Large Span Steel Dam Gate in Haihe River Basin
With the development of national economy and the improvement of living standards,people's demand for a beautiful aquatic ecological environment is also increasing.In the urban ecological water storage project,the steel dam gates can create wide water surfaces and waterfalls due to their lack of superstructure,creating a good ecological water landscape.At the same time,they also have the advantages such as safety,stability,strong flow capacity,and long service life,and have broad application prospects.However,most of the existing steel dam gates have relatively small spans and are arranged across the entire river section,and the design of large span and high head steel dam gates is less common.According to the characteristics of the main channel of Haihe River basin,this study puts forward a typical design scheme of arranging large-span steel dam gate along the main channel of the river,with control equipment placed on the outside of the embankment.The related structure design,foundation treatment and steel gate design have certain reference for the arrangement of steel dam gates in similar river channels.
