6、建筑物设计。该闸有如下的作用：（1）防洪。当胜利河水位较高时，关闸挡水，以防止胜利河的高水入侵团结渠下游两岸的底田，保护下游的农田和村镇。（2）灌溉。灌溉期引胜利河水北调，以灌溉团结渠两岸的农田。（3）引水冲淤。在枯水季节。引水北上至下游红星港，以冲淤保港。1.12设计资料（1）团结渠为人工渠，其断面尺寸如图1所示。渠底高程为2194.5m，底宽50m，两岸边坡均为1：2。（比例1：100）图1-1团结渠横断面图（单位：m）（2）灌溉期前进闸自流引胜利河水灌溉，引水流量为300。此时相应水位为：闸上游水位2201.83m，闸下游水位2201.78m；冬春枯水季节，由前进闸自流引水至

7、下游红星港，引水流量为100，此时相应水位为：闸上游水位2201.44m，闸下游水位2201.38m。（3）闸室稳定计算水位组合：设计情况，上游水位2204.3m，下游水位2201.0m；校核情况，上游水位2204.7m,下游水位2201.0m。消能防冲不利情况是：上游水位2204.7m,下游水位2201.78m，引水流量是300（4）下游水位流量关系：流量0.0050.00100.00150.00200.00250.00300.00水位H(m)2201.002201
