经过水利技术人员多年的实践和推广，混凝土u型渠道机械施工水平得到了进一步提高，尤其是混凝土u型防渗渠道施工成套产业化机械的研发和推广，使混凝土u型渠道的施工速度加快，且混凝土质量高，使其在不同的地形、气候和使用条件下的大中小型渠道和农业节水灌溉工程建设中得到了广泛的应用。
After years of practice and promotion by water conservancy technicians, the construction level of concrete U-shaped channel machinery has been further improved, especially the R & D and promotion of complete set of industrialization machinery for concrete U-shaped anti-seepage channel construction, which makes the construction speed of concrete U-shaped channel faster, and the concrete quality is high, making it in different topography, climate and use conditions of large, medium and small channels and agriculture Water saving irrigation engineering construction has been widely used.
渠道输水是农田灌溉的主要输水方式。传统的土渠输水渗漏损失很大，为减少渗漏损失，许多灌区更新改造、农业综合开发等项目，通过加大渠道防渗工程建设，以缓解农田灌溉缺水的矛盾。在渠道的各种防渗方式中，u型渠道防渗节水的潜力很大，是应优先考虑的重要技术之一。
Canal water delivery is the main way of farmland irrigation. In order to reduce the leakage loss, many projects such as irrigation area renovation, agricultural comprehensive development and so on, through increasing the construction of canal seepage control engineering, to alleviate the contradiction of farmland irrigation water shortage. Among all kinds of seepage control methods of canal, U-shaped canal has great potential of seepage control and water saving, which is one of the important technologies that should be given priority.
