堤防漏洞查堵演示试验技术研究

堤防漏洞险情为较高水位情况下堤防背坡出现贯通堤身的流水孔洞，是堤防八大险情之一。漏洞险情发展快、危害大、抢堵难度大。为提高防汛专业队伍查堵漏洞的技术水平，封丘县黄河河务局于１９９７年７月１８晶，在曹岗险工０－１号坝之间，进行了堤防漏洞查堵演示试验。演示的目的是模拟不同条件下出现的各种漏洞险情，试验条件探找洞口和抢堵漏洞的方法，研究各种抢堵方法的可操作性和适用条件，提高抢险堵漏洞的技术水平。

Study of Demonstration and Experiment Techniques in Check and Block of Leaks in Dykes

Being one of eight dangers in dykes, leak danger in dykes is a hole with waer flowing out thromp dyke when water lev-el is comparedly high which is chararterized of fast developing, heaby dangmis, and difficult to block. In order to promote the technic level of flood provention teams for checking and blocking leaks, demonstheion and experiment for checking and blocking leaks wer carried out by the Yellow River Affair Bureau of Fengqiu County in Caogan dangeros site betwee dams No. 0-1 on 18 July 1997. The eXPeriment almed at stimulating vallous leak dange in different conditions, demonstrating methods for finding and mshing to block holes, researehing the capabilities and application conditions for various methods, and promoting the technic levels for mshing dangers and blocking leaks.Keywonds: leaks in dykes, leak check, leak block, method, experiment, Caogang dangrous site
