摘　　要：因受月季园北园及月季大道工程建设影响,白桐干三支进水闸至黄庄西南节制闸渠段被填埋,下游农田无法得到灌溉,影响灌区整体效益发挥和农民切身利益,要求恢复干三支渠输水功能的任务已迫在眉睫。为此,南阳市城乡一体化示范区启动“南阳市月季园东园应急排水及白桐干三支渠恢复工程”项目。开展白桐干三支渠恢复工程设计实践表明,全面了解工程概况,分析白桐干三支渠现状特点,分别就工程的箱涵段和明渠段两部分着重构造技术设计,以恢复干三支渠原有工程设计目标,同时通过渠道水力计算获得渠道设计断面成果;最后注重相关管线迁建保护设计。可为类似支渠渠道工程设计借鉴参考。Due to the influence of the construction of the north area of Yueji Garden and the Yueji Avenue project,the section from the three branches sluices of Baitong Channel to the southwest gate of Huangzhuang was buried.Therefore,the downstream farmland could not be irrigated,which affected the overall benefit of the irrigation area and the vital interests of farmers.It is urgent to restore the function of the three branches of the dry channel.To this end,Nanyang City Rose Garden East Garden Emergency Drainage and Three Channels of Baitong Channel Restoration Project were carried out.The design practice of Baitong Channel three branch canal restoration project showed the following two points.First,the general situation of the project was comprehensively understood.The current characteristics of the three branches of Baitong Channel were analyzed.The technical design of the box section and open channel section was emphasized to restore the original engineering design objectives of the three branches of the main channel.At the same time,the results of channel design section were obtained through channel hydraulic calculation.Finally,the protection design of relevant pipeline relocation was paid attention to.It can be used as reference for similar branch channel engineering design.
