Application of Clear Diverting Idea in Urban River Landscape Water Storage Design
This paper is based on the comprehensive management project of South River Bend in Huating County,Gansu Province.Under the premise of fully analyzing the current characteristics of the South River Bend in Huating County,the design idea of using rectangular channel open section to store clear water and culvert to drain muddy water is proposed,firstly,the culvert is designed to drain the flood according to the allocated flow rate,and then,reinforced concrete weir,rubber dam,steel dam are selected.By comparing five aspects such as functionality,operation,operation time,operation reliability,and safety,the steel dam was finally selected as the water storage building in this case.Finally,based on the calculated value of the specification,the structural design of the steel dam cover,gate chamber,dissipation pool,and sea rover was carried out,and the operation mode of the steel dam in flood season and non-flood season was explained.
