沟渠衬砌技术近年来发展较快,类型较多,是节约用地、节省用水、增加产量、方便管理、提高灌溉效益的有效途径;相对土渠而言,显示出防渗效果好、糙率小、允许流速大、强度高、使用年限长等多方面的优越性,靖江属通南地区,土质偏沙,易被冲刷,且地少人多,因此,应用和推广沟渠衬砌十分适宜且很有必要。从1991年开始,靖江市先后在19个乡镇试验和推广沟渠衬砌,累计实施长度105km,控制灌溉面积1.4hm~2,取得了良好的社会效益和经济效益,结合实践,本文就主要几种类型沟渠衬砌的设计,施工
Drainage lining technology developed rapidly in recent years, more types, is to save land, save water, increase production, facilitate management and improve irrigation efficiency of the effective way; relative to the soil canals, showing good seepage effect, roughness, Allowing a large flow rate, high strength, long service life and many other advantages, Jingjiang belongs to the south, sandy soil, easy to be washed, and fewer people more, so the application and promotion of trench lining is very appropriate and necessary . Since 1991, Jingjiang City has tested and popularized the lining of ditches in 19 villages and towns, successively implemented the length of 105km and controlled the irrigation area of 1.4hm ~ 2, and achieved good social and economic benefits. Combining with practice, Drainage lining design, construction
