快速设置装配式防洪子堤的设计及应用

Design and application of quick-setting assembling sub-embankment for flood prevention

针对防洪工程要求和目前防洪子堤技术存在的问题,提出了可折叠的装配式防洪子堤的设计思想,进行了子堤的材料性能试验和结构设计,研制了一种装配式玻璃钢桐木夹层防洪子堤。通过对子堤在土堤和混凝土堤表面挡水试验和快速设置技术的应用研究,表明该防洪子堤具有重量轻、可重复使用和快速设置等特点,特别适合在需要临时加高的水库大坝、江防大堤和城市河岸堤防工程中使用。

Based on the demand of flood prevention and problem of setting for the sub-embankment,a kind of sub-embankment for flood prevention is set up.The sub-embankment is foldaway and assembling.The material performance tests and structure design on sub-embankment have been carried out.A kind of assembling sub-embankment for flood prevention with sandwich structure of GFRP-TT(glass fiber reinforced plastic and Tung Timber) has been developed.Through waterproof testing and application study of quick-setting sub-embankment on clay bank and concrete bank,the results show that the sub-embankment for flood prevention has the characteristics of light,repeatable usage,quick setting,etc.It is quite suitable for the application in the temporary heightening for reservoir dam,great riverbank and riverside in cities.
