30多年来,沿黄广大军民在与黄河洪水搏斗的实践中积累了丰富的斗争经验,创造了一套切实可行的防汛抢险技术,现将重点归纳介绍如下,供大家参考。一、防止漫溢预报洪水继续上涨可能超过现有堤顶高程时,就有漫堤溃决危险,必须突击加高。由于时间紧,不允许把堤身全部加高培厚,只能先在堤顶上抢筑子埝临时挡水,防止洪水漫溢堤顶。子埝要筑在堤顶迎水一侧,修前应先清除堤顶草皮,使新旧土易于结合,不要修在大堤当中,以免阻碍交通,增加抢险困难。子埝高度应根据水情决定,事先要计算一下洪水到来还有多少时间,需要多少人工,务必在洪水到来之前完工。抢筑时要全段同时开工,分层填筑,不能等筑完一段再筑另一段,以防造成在低处漫水。子埝有以下几种:
Over the past 30 years, a large number of soldiers and civilians along the Yellow River have accumulated rich experience in fighting wars with the Yellow River flood and created a set of practical flood control and emergency measures. The key points are summarized as follows for your reference. First, to prevent flood forecasting Flood continued to rise may exceed the existing embankment elevation, there is danger of collapse of the embankment must be raided higher. Due to the tight schedule, it is not allowed to raise the embankment all the time, and only the submarine should be temporarily blocked at the top of the dike to prevent the overflowing of the dike. Children should be built on the embankment to meet the water side, before repairing the dike turf to make the old and new soil easy to combine, not to repair the embankment, so as not to hinder the traffic and increase the rescue risk. The height of subfloor should be decided according to the water conditions. Beforehand, it is necessary to calculate how much time it takes for the flood to arrive and how much labor is needed, so it must be completed before the flood comes. To build the whole block at the same time to start the construction, stratified filling, can not wait to build a section and then build another section to prevent the formation of low water. Sub-埝 have the following:
