由于U型渠道的防渗效果好,输水水流流态顺,水量损失小,施工方便,占地少,是一种理想的渠道节水设施。近年来随着施工工艺和施工机械技术的发展,U型渠道施工技术在灌区渠道节水改造中得到了不断推广和应用。文章结合人民胜利渠灌区渠道节水改造工程,介绍了U型渠道的一些优点和U型渠道的施工技术要点,分析了工程效益。
Due to the good seepage prevention effect of the U-shaped channel, the water flow is smooth, the water loss is small, the construction is convenient and the occupied area is small, which is an ideal channel water saving facility. In recent years, with the development of construction technology and construction machinery technology, U-shaped channel construction technology has been continuously popularized and applied in the water-saving transformation of the canal irrigation channels. In this paper, some advantages of U-shaped canal and key points of construction technology of U-shaped canal are introduced, and the project benefit is analyzed according to the canal water-saving reconstruction project of People’s Victory Canal Irrigation District.
