混凝土U形渠在北方地区的应用

摘要

混凝土U形渠道以造价低、进度快、过流能力大、沿程水头损失小、防渗效果好等特点被迅速推广应用。在中国北方地区由于冬季气温较低，在U形渠出现初期使用较少，但是随着U形渠工艺、技术的不断改进，经过大量实践后也迅速的被广泛使用。%Concrete U shaped channel with the characteristics of low cost, fast progress, big discharge ability,small frictional head loss and good anti-seepage effect etc.was rapid popularized and applied rapidly.In Chinese north area due to the low winter temperatures,the U shaped canal r was not used widely at the earlier stage of its being created ,with the continuous improvement on its technology,it was widely used through practice.
