摘　　要：天然钠基膨润土防水毯是被广泛用于建筑工程、垃圾填埋场、地铁工程、隧道、水库、引水渠道、景观湖等领域的实用技术,但由于市场价格高,因此对其应用受到限制。本文通过天然钠基膨润土防水毯在浑北灌区南干渠上的应用,从技术、经济两方面进行分析认为,具有天然、优异的防渗作用,显著减少渗漏损失。并且施工快捷简单,能有效缩短工期,节省施工成本和后期运行管理费用。为在渠道防渗工程上推广应用,提供了参考。The natural sodium-base bentonite waterproof carpet is a practical technology,widely used in the field of building engineering,landfill site,subway engineering,tunnel,reservoir,diversion channel,landscape lake,etc.However,its application is limited because of the high market price.Based on the application of the natural sodium-base bentonite waterproof carpet in south main canal of the Hunbei irrigation,the paper thinks that which has the natural and excellent anti-seepage effect to significantly reducing seepage loss from the view of the technique and economic aspects.The quick and simple construction could effectively shorten the construction period to save the construction costs and the late operation and management costs.It supplies reference for extensional application in channel anti-seepage projects.
