@崩塌堤岸的抢护方法及步骤如下：钠基膨润土防水衬垫/浙江宁波膨润土防水毯-检测

@此外，应当说明，土工合成材料在上述的某些方面目前应用尚不普遍，如堤的防渗等，为此本章将引用一些类似的在低土坝中的应用实例作为参考，以期促进土工合成材料在堤防中应用。

江西瑞昌市乌鱼爪堤段的地基为透水性强的土层。1983年汛期高水位时堤基出现了大量的泡泉群，曾用填土压载的办法来处理但效果不理想，泡泉仍屡屡出现，后改用纵横排水的办法来处理。即在堤脚挖沟，沟表面铺非织造土工织物起反滤作用，然后在沟中填碎石料，排水沟中的水由横向排水管导出，直接排入田间。沟顶用回填土作盖重，见图3-15。该工程于1988年上半年竣工，经历多年汛期洪水考验，尤其是1995年洪水位为历史高记录，土工织物过滤

国外大量用于道路的土工复合材料是玻纤聚酯防裂布和经编复合增强防裂布。能延长道路的使用寿命，从而极大地降低修复与养护的成本。从长远经济利益来考虑，是国内应该积极采用和提倡土工复合材料。 钠基膨润土防水衬垫/浙江宁波膨润土防水毯-检测
