模袋混凝土是近年发展起来的新型护岸技术 ,具有施工速度快、工效高、工期短、护坡面美观、整体性好等优点。目前国内模袋混凝土护坡大多用于水上护坡及内河水深较浅河段护坡 ,对于长江河道水下护岸 ,目前存在的最大困难是水深流急条件下的施工方法、施工工艺 (包括施工机械、冲灌、沉放 )等问题。通过在长江九江河段马湖堤江岸模袋混凝土实验工程 ,总结探索出深水模袋设计方法及施工工艺。
Bagging concrete is a new type of bank protection technology developed in recent years. It has the advantages of fast construction speed, high work efficiency, short construction period, beautiful slope protection surface and good integrity. At present, most of the bagged concrete slope protection in China is used for water slope protection and inland water depth protection of shallow river. For the underwater revetment of the Yangtze River, the biggest difficulty currently exists is the construction method and construction technology (including construction machinery, Irrigation, sinking) and other issues. Through the experimental design of bagged concrete at the bank of Mahu embankment in the Jiujiang reach of the Yangtze River, the design method and construction process of the deep-water mold bag are explored.
