引江济汉通航工程高石碑船闸输水系统布置

根据引江济汉通航工程特点及船闸总体布置,按照《船闸输水系统设计规范》的要求,研究确定了高石碑船闸不设镇静段的短廊道集中输水系统形式,计算了输水阀门处廊道断面的面积及输水系统特征尺寸,并进行了输水水力计算。水力计算结果表明:设计的船闸输水系统输水水力特性达到了预期的目标,确定的输水阀门开启方式合理,采用的双明沟消能布置适合高石碑船闸没有帷墙的工程特点。

Layout of filling and emptying system of Gaoshibei shiplock of water transfer project from the Yangtze River to Hanjiang river

According to the demands of the Design Code for Filling and Emptying System of Shiplocks and the layout characteristics of the shiplock of the water transfer project from the Yangtze River to Hanjiang river, this paper determines the type of filling and emptying system of Gaoshibei shiplock to be short-culvert concentrated filling and emptying system with no need of mitigative segment, calculates the area of the culvert transect at the valve and the key dimension of the filling and emptying system, and carries out hydraulic calculations of lock filling and emptying. The study results indicate that the hydraulic characteristics can fulfil the criteria and design demands and the valve opening modes are reasonable. Moreover, because there is no curtain wall at the lockhead, the double open ditch dissipation is suitable for Gaoshibei shiplock.
