通州湾粉砂高滩潮沟类特殊地段人工水上护底施工工艺

Construction technology of artificial water bottom protection in high silt-muddy flat tidal creek special area of Tongzhou Bay

土工织物作为滩地护底工程施工中重要的结构,施工工艺成熟,在国内外河流及围堤护底工程中得到广泛应用,但在粉砂高滩潮沟类特殊地段进行人工护底施工还没有类似的实例。文章通过南通通州湾匡围工程成功的施工案列,介绍粉砂高滩潮沟类特殊地段护底施工技术,对软体排的制作,搭接及施工工艺进行阐述。

The geotextile is an important structure in construction of beach bottom protection works, its construction technologyis mature, and is widely used in the bottom protection of river and embankment at home and abroad. But in the high silt-muddyflat tidal creek special area, the artificial bottom protection construction has not been a similar example. Combined with thesuccessful construction case of inning project in Nantong Tongzhou Bay, we introduced the bottom protection constructiontechnology in high silt-muddy flat tidal creek special area, and described the production,lapping and construction technology ofsoft mattress.
