近年来青铜峡河东灌区东干渠灌域引水量不断增大，引发了诸多问题，加快东干渠灌域的节水改造进程势在必行。结合东干渠银平公路桥至吴白公路桥段渠道实际状况，在衬砌改造中考虑了冻胀、边坡滑塌、地下水位高等多种不利因素，采取土工膜防渗，现浇混凝土弧形坡脚、聚苯乙烯板、坡脚铺设排水暗管等防冻胀措施，采取格宾石笼排除渠道基土内的水分、消除流沙段边坡滑塌的排水措施。并通过方案比选，提出了具体衬砌方案。

In recent years due to the increase of diversion volume of east main canal irrigation area,it has caused many problems. To speed up the process of the east main canal irrigation water-saving transformation domain has been imperative. It combined with the actual situation of the section from Ying-Ping Highway Bridge to Wu-Bai Highway Bridge of east main canal and made full use of“preliminary research results,the Ministry of Water Resources in 2013 public industry special fund project of Ningxia Yellow River Diversion Canal Irrigation Area”key technologies research of water distribution in the lining,transformation,the frost heave,slope collapse,high underground water level of various unfavorable factors,adopt-ed geomembrane,cast-in-place concrete arc slope,polystyrene board,the foot laying drainage pipe anti-freezing measures,took the gabion material removal channel soil's moisture,eliminated the drainage measures of slope slide quicksand and scheme selection through comprehensive analysis, the lining. At the same time,it made specific requirements for the main technical indexes of the lining of canals.
