水泉水闸底板溢流堰设计与应用

Design and application of sluice floor overflow weir for Shuiquan

在水泉水闸工程设计中,采用了新型的水闸底板溢流堰结构型式,既满足了工程效益、淹没及占地等条件,又解决了水闸的泄量、消能等问题。设计完成后,对该工程的泄量计算及溢流堰水流流态进行水工模型试验。工程运行期间,又对较大洪水进行了实型观测。试验及观测结果证明:工程设计技术指标与试验数值及观测结果相符,工程运行期间,对水闸底板溢流堰位移观测,均小于规范规定值。水泉水闸水力自动翻板闸泄流安全稳定,消能效果良好,达到了设计要求。

In the design of the spring sluice project,a new type of overflow weir structure is adopted,which satisfies the conditions of Engineering benefit,submergence and land occupation,and solves the problems of sluice discharge and energy dissipation.After the design is completed,the discharge calculation of the project and the flow pattern of the overflow weir are tested by hydraulic model.During the operation of the project,large floods were observed.The results of experiment and observation show that the technical indexes of engineering design are consistent with the experimental data and observation results,and the design is on the safe side.It is proved that the design and application of the overflow weir on the floor of the spring sluice are successful both in theoretical research and practical application.During the operation of the project,according to the relevant technical specifications,the displacement observation of the overflow weir of the sluice floor is less than the specified value of the specifications.The hydraulic automatic turning gate of the spring sluice can be used freely,the discharge is safe and stable,and the energy dissipation effect is good,which meets the design requirements.
