摘要
论述了渠道衬砌与防渗的涵义和作用,阐述了我国渠道衬砌与防渗技术的发展现状、存在问题以及在衬砌与防渗新材科、新型衬砌与防渗结构形式、防冻胀技术、机械化施工技术等方面的发展趋势,认为我国渠道衬砌与防渗技术与发达国家相比在许多方面还存在一定差距,特别是在工程施工质量和施工机械化水平方面差距较大,指出目前我国渠道衬砌与防渗技术由单一材料向复合材料、单一结构向复合结构、以人工施工为主向半机械化及机械化施工方向发展,并开始重视渠道衬砌与防渗对生态环境的影响。
This paper discusses the meaning and role of canal lining and seepage control, and expounds the present development status and existing problems of canal lining and seepage control techniques in Chinaas well as development trends of new material, structur- al forms, anti-frozen technology and mechanization construction technology. Compared with developed countries there is still dispari- ty in many aspects,especially greater disparity in construction quality and mechanization construction. The authors point out that ca- nal seepage control technology has developed from single seepage control materials to compound materials, from single seepage con- trol structures to compound structures, from manual construction to semi-mechanized and mechanized construction, and impact of canal lining and seepage control on ecological environments.
