过去淮河洪水泛滥成灾,经过新中国50多年的治淮建设,淮河大堤防洪能力大大提高,使洪水得到了初步控制。但由于部分沿淮堤防是在历史民埝基础上逐步加修的,甚至有的堤身是在历史决口口门堵复后形成的,堤基基础复杂,堤身内土质不均匀,存在险点隐患。汛期一旦发生大堤长时间偎水,仍会造成险情,其中漏洞险情是各类险情中比较产重危险、也是较难抢护的险情之一,若抢护不及时,易造成堤防决口,给当地人民生命财产造成巨大损失。1991年和2003年的特大洪水中,沿淮堤防都曾经出现过漏洞,造成险情。多年来,沿淮水利工作者在与洪水的持续斗争中,对于抢堵堤防漏洞,获得了许多认识并总结出许多可行的方法。
In the past, floods in the Huaihe River flooded. After more than 50 years of new China’s construction of Huaihe River, the flood control capability of the Huaihe River embankment has been greatly enhanced, and floods have been initially controlled. However, part of the embankment along the Huai River is gradually being built on the basis of historical princes. Even some embankments are formed after the historic closure of the embankment. Due to the complex embankment foundation and uneven soil quality in the embankment, there are risks of danger . Once the embankment flood season for a long time snuggling, will still cause danger, of which dangerous danger is more dangerous in all kinds of dangerous situations, but also more difficult to steal the danger of one, if not in a timely manner to steal the embankment, easy to cause dykes to the local People’s lives and property caused great losses. During the floods of 1991 and 2003, there were loopholes in the embankments along the Huai River, causing dangerous conditions. Over the years, along with continuous efforts of floodwaters, along the Huaihe River water conservancy workers, they have gained a lot of understanding and summed up many feasible methods for grabbing loopholes in embankments.
