桂平二线船闸闸底长廊道输水系统布置研究

Arrangement of lock bottom long-culvert filling & emptying system of Guiping Second-lane lock

根据《船闸输水系统设计规范》和桂平二线船闸地质条件的具体特点,确定了输水系统型式,计算了输水阀门处廊道断面的面积。在调查分析大量资料基础上,设计了桂平二线船闸输水系统各部位的型式、主要尺寸和闸室消能布置,估计了输水系统的流量型式。水力计算表明:设计的输水系统水力特性满足要求。

According to the Design Code for Filling ＆ Emptying System of Shiplocks Design and in view of the geologic condition of Guiping Second-lane lock,we determined the type of the filling ＆ emptying system and calculated the cross-sectional area of the culvert where the valve locates.Based on the investigation and analysis of a lot of data,we designed the type of each part and main dimensions of the filling ＆ emptying system and the arrangement of the energy dissipating device in the lock chamber.We also estimated the discharge mode of the filling ＆ emptying system.The hydraulic calculation proves that the hydraulic features of the designed filling ＆ emptying system meet the requirement.
