黄河溃口的危险依然存在。如充分利用橡胶坝充胀速度快、移动方便等优点,在决口口门的上游设置橡胶坝围堰,给口门的堵复创造有利条件,则可以达到汛期快速堵复决口、减少水灾损失之目的。通过论证橡胶坝围堰快速堵口技术的可行性,分析了无基础橡胶坝围堰快速堵复决口技术存在的问题及解决途径,并总结了现场试验结果,提出进一步的改进意见。由分析计算和现场试验得出结论:在围堰处流速不大于 3 m/s、水深不大于 5 m的条件下橡胶坝围堰可以作为黄河决口快速堵复的一种新技术。
The danger of the Yellow River breach still exists. If full use of rubber dam inflation speed, easy to move, etc., set up in the upstream of the mouth of the decision to set up rubber dam cofferdam to the door to create favorable conditions for plugging, you can achieve fast blocking flood season burst, reducing flood damage purpose. By demonstrating the feasibility of the quick plugging technology for rubber dam cofferdams, the problems and solutions to the fast plugging plugging technology for base cofferdams without cofferdam are analyzed. The results of the field test are summarized and further improvements are suggested. It is concluded from the analysis and calculation and field test that the rubber dam cofferdam can be used as a new technology to rapidly block the Yellow River burst under the conditions that the flow velocity at the cofferdam is not more than 3 m / s and the water depth is not more than 5 m.
