摘  要:
渠道防渗是灌区充分利用水资源、扩大灌溉面积的关键性措施之一。目前主要采用土料防渗、水泥土防渗、砌石防渗、混凝土防渗、膜料防渗等形式进行渠道防渗,不同防渗形式的技术原理、技术要点、适用条件、效果及推广条件差异明显。以宿迁市船行灌区节水改造工程为案例,分析表明,渠道防渗后,显著提高了渠系水利用系数,节约了投资和运行费用,年节水效益达191.72万元,并结合生态防渗技术的推广,渠道防渗生态效益明显。

摘  要:
Canal seepage control was the most important technique to use water resources efficiently and expand irrigation area.The canal seepage control techniques include clay seepage control,cement-soil seepage control,stone seepage control,beton seepage control and film seepage control.All the seepage control techniques have different technical principles,technical points,applicable conditions,benefits and extension conditions.The study chose the irrigation improvement project in the Chuanhang irrigation district of Suqian City as the case.The analysis results shown that the canal seepage control technique improved utilization coefficient of canal system water significantly,saved investment and running fare.The benefit of saving water resource reached to 191.72 ×104 Yuan per year.With the extension of ecological seepage control technique in the Chuanhang irrigation district,the ecological benefit of canal seepage control was increased significantly.
