一、工程概况 涡河涡阳闸位于毫州市涡阳县县城北部的涡河上,为涡河本干大型节制闸,闸室总宽118.8m,共22孔,每孔净宽4.0m,具有蓄水、排涝、泄洪等功能。该闸始建于1958年,原设计流量1600m3/s,校核流量2100m3/s,因1963年和1965年洪峰流量均超过设计流量,1969年按3000m3/s(模型试验值,落差0.37m)进行改建,改建工作 First, the project profile River vortex Xuan Yang is located in the city of Guoyang County, whirlpool on the northern part of the river, the river vortex stem large gate, gate total width of 118.8m, a total of 22 holes, each hole net width of 4.0m, with water storage, Drainage, flood discharge and other functions. The gate was built in 1958, the original design flow of 1600m3 / s, check the flow of 2100m3 / s, because 1963 and 1965 flood peak flow exceeded the design flow in 1969 by 3000m3 / s (model test value, the gap 0.37m) To reconstruct, rebuild the work
