北方平原区小型渠道水泥土防渗的应用研究

针对北方平原区水源紧缺、小型渠道数量多、土渠渗漏严重，防渗渠道发展缓慢，严重制约着节水农业发展的现实问题；通过“水泥土水泥砂浆复合材料渠道衬砌实验研究”，对水泥土水泥砂浆复合材料渠道衬砌试验工程进行了系统的试验、观测、分析；实验证明在北方平原地区充分利用当地土料进行农田灌溉渠道防渗具有节水效果显著、抗冻性能好和就地取材，造价低等优点，是值得推广的实用经济的防渗节水技术，对加快农田节水工程建设具有十分重要的现实意义

A Study on the Application of Cement-treated Soil in Controlling Small Canal Seepage in Northern Plain

The deficiency of water resources,numbers of small canals,serious seepage loss in the small canals and slow development in preventing canal seepage greatly restrict water-saving agriculture in north plain in china.In order to solve the problem,an experiment was carried out using Cement-treated soil and cement mortar composite materials for canal lining.During the experiment,systematic observations and analysis were made.The results show that use of local soil as lining material for preventing farm irriagtion canal seepage has many advantages: in addition to saving water,it has a high freezing-resistance characteristic;it is easy to be obtained in any place where needed and it has a low cost.For these reasons,utilization and extention of this practical and economical technique is very important for rapid development of water-saving project.
