Layout and hydraulic analyses of the filling and emptying system of Gaogang second-line shiplock on the Yinjiang River

结合高港二线船闸工程具体条件,按照《船闸输水系统设计规范》的要求,研究确定了船闸短廊道和三角门门缝联合输水的输水系统型式及具体布置方案,计算分析了充泄水阀门开启方式,通过建立船闸联合输水数学模型计算了闸室输水水力特性.结果表明,确定的船闸输水系统布置及阀门开启方式是合适的,相关水力指标满足规范及设计要求;设计的消能工布置适合高港二线船闸工程特点,可获得较好的闸室水流条件;同时根据水力特性计算结果提出了阀门启闭系统设计建议.

According to the specific characteristics of the Gaogang second-line shiplock and the Design Code for Filling and Emptying System of Shiplocks, the lock＇s short culvert associated with sector gate gap filling and emptying system is adopted and the detailed layout has been analyzed and determined. At the same time, the valves＇ opening modes are calculated. The hydraulic characteristics during lock filling and emptying are calculated through the lock filling and emptying mathematical model. The calculated results indicate that the dimensions of the filling and emptying system and the valves＇ opening modes are appropriate and the hydraulic characteristics can meet the relevant requirements of the code and the design. The suggested dissipation type is suitable for the Gaogang second-line shiplock and preferable flow condition may be obtained in the lock chamber. Furthermore, the design proposal for the open-close system of the valve and the gate is put forward in the study.
