吸水速凝挡水子堤在抗洪抢险中的应用

Application of a new summer dike to flood fighting

吸水速凝挡水子堤是由土工织物做外袋、土工膜做内袋和装在内袋里的高效保水材料以及护垫、加强带、注水孔、防渗带、防渗条等组成。袋体吸(充)水后体积胀大,随即水体凝结成具有一定抗压强度能自立的凝胶体,从而沿堤顶形成一道连续防洪矮墙。这是一项防止洪水漫顶、抗御风浪、快速有效的新技术成果。

The summer dike consisting of water absorbing and quick setting material is made of the outer geotextile bag-form, the geomembrance inner bag-form with the effective water-retaining material inside and protecting cushion, reinforcing band, water injection hole, anti-seepage strap etc. After sucking enough water, the bag-form of the dike is to be inflated, and then the inside material is to be formed into a self-standing gelled body with a certain compressive strength as well; with which a continuous stub flood wall along the levee crest is to be formed. This is an achievement of a new technique for flood fighting with the features such as prevention of flood overtopping, wave resistance and quick installation etc.
