某灌区干渠排水工程1~#退水渠设计研究

Study on the Design of NO.1 Drainage Channel of Main Canal Drainage Project in an Irrigation Area

灌区续建配套与现代化改造建设中,干渠退水渠设计对工程安全运行具有重要意义。结合某灌区刁南干渠1~#退水渠(桩号0+800~2+065段)进行全段衬砌工程案例,了解工程概况,着重围绕渠道衬砌断面比选、渠道防渗衬砌方案比选、水力计算、渠道设计及渠道冲淤复核等几部分详细分析研究灌区大型退水渠设计的基本内容。完成了刁南干渠1#退水渠(桩号0+800~2+065段)工程的复核及设计成果,可为类似灌区现代化改造提供参考。

In the construction of continuous supporting facilities and modernization of irrigation area, the design of main channel and drainage channel is of great significance to the safe operation of the project. Combined with the Diaonan Canal NO.1 drainage channel(pile NO. 0+800~2+065 section) in an irrigation area, the general situation of the whole section lining project is understood. The basic contents of large-scale outlet channel design in the irrigation area are analyzed and studied in detail focusing on the comparison and selection of channel lining section, comparison and selection of channel anti-seepage lining scheme, the hydraulic calculation, the channel design and channel scouring and silting review. The review and design results of Diaonan Main Canal NO.1 drainage canal(pile NO. 0 + 800~2 + 065 section)project have been completed, which can provide reference for the modernization of similar irrigation areas.
