弧脚梯形渠道混凝土衬砌施工技术

On Construction Technique of Concrete Lining of Trapezoidal Canal with Curved Slop Toe

通过对七一渠梯形断面改造施工,介绍了弧脚梯形断面混凝土衬砌技术在施工中的应用,它可降低渠道糙率,解决梯形断面渠道坡脚淤积问题,节约清淤费用,提高渠道水的利用率。

Through construction to reform Qiyi canal＇s trapezoidal cross-section,the paper introduces the application of concrete lining technique of trapezoidal canal with curved slop toe in this project.This technique can raduce canal roughness coefficient,can solve problem of sediment deposition in curved slop toe of canal,can save sediment removal cost and can raise water efficiency of canal.
