渠道砼衬砌是渠道防渗的有效措施,特别是小型渠道采用U形砼衬砌,在同一设计流量下可比梯形衬砌省料20％,节约土地三分之一,而且抗冻胀和输冰能力强。但这种渠道若依靠人力施工,则工效太低,浪费材料,质量不易保证。陕西省宝鸡峡灌区研制成了适宜于田间配套使用的U形渠道砼衬砌机。该机用柴油机作震捣,用柴油机所带动的卷扬机作牵引,工
Channel concrete lining is an effective measure for canal seepage control. Especially for small channels, U-shaped concrete lining can save 20% compared with trapezoidal lining at the same design flow rate, save one third of the land, and can resist frost heaving and ice transportation . However, if such channels rely on manpower construction, the work efficiency is too low, waste of materials, quality is not easy to guarantee. Shaanxi Province Baoji Gorge irrigation area developed into a suitable U-shaped channel for supporting the field of concrete lining machine. The machine used for vibrations diesel engine, driven by a diesel engine winch for traction, work
