Zhengzhou people surprisingly recruit hardcore flood control. How can flood control work?

In fact, if the flood disaster is very serious, no matter what flood control methods we use, it will have no effect, which is actually reflected in the rainstorm in Zhengzhou. Zhengzhou itself is a sponge city, which has invested a lot of money, but it still can't play much role in the face of heavy rain, so no flood control method is sure to work. If the flood is strong enough, you can only take shelter on high floors, and everything on the ground can't avoid being soaked.

First of all, underground garages and supermarkets were the worst victims of the flood. At present, the most effective flood control method in these underground places is to use sandbags, which can block the impact of floods. But sandbags can't completely block the water source, so underground places also need to have basic drainage capacity, and we also need to ensure that sandbags are strong enough, otherwise they won't play any role in the face of floods.

Secondly, in our flood control work, in fact, the most important thing is to rescue and avoid disasters. The rainstorm disaster in Henan province in July caused so many deaths because everyone was affected without warning, so when the rainstorm warning appeared, Zhengzhou municipal government deployed rescue workers in advance and implemented it? Commuting at the wrong peak? The new system is to ensure that the fewer people appear on the street, the better. Only in this way can the difficulty of rescue be alleviated, and other citizens had better stay at home and not go out.

In addition, when the flood disaster comes, tap water can only be used for flushing toilets and washing clothes, so it is necessary to develop the habit of storing water at home. Many people may rely on the water purifier, but when the flood disaster comes, the purifier is of no help. Finally, if the flood control work wants to play a role, it is necessary to ensure that attention is paid to every place and all flood control measures should be arranged in place.
