California 1 expressway collapsed in the rainstorm! How destructive is the rainstorm?

California 1 expressway collapsed due to heavy rain, and the destructive power of continuous heavy rain is very great. This is because rainstorm is a natural phenomenon, and a lot of rain falls from the sky. During heavy rain, too much rain may lead to loose soil, which in turn may lead to dangerous situations such as mudslides and landslides. If there is a rainstorm in cities and other places, the drainage system cannot discharge rainwater through the system for a period of time after the load is exceeded, and there will be a danger of urban waterlogging. Therefore, heavy rain will have a great impact on people's lives. Whenever it rains, people's travel will be hindered. Persistent heavy rain will affect people in cities and mountainous areas, so when heavy rain occurs, we should pay attention to the weather forecast in time and take preventive measures.

Due to the attack of heavy rain, the structure of many pavements may change to some extent. Some roads are actually built on underground rivers, so the structure of these roads may be damaged by the influence of heavy rain. So during the rainstorm, we may hear the news that the rainstorm caused the road surface to collapse somewhere. Therefore, during driving, we should be cautious and pay attention to the road conditions to avoid the danger of collapse. When there is a rainstorm, the most important thing is to clean up the rain. Relevant departments should inspect the drainage system of the city, and at the same time give early warning to places that may be flooded, such as tunnels and parking lots. And tell everyone what to pay attention to through the radio, so as to reduce people's losses when the rainstorm comes.

In many coastal areas, heavy rains are usually caused by tropical cyclones. Therefore, the arrival of rain will be accompanied by dangers such as typhoons. In rainstorm weather, we need to travel as little as possible, because if there is a typhoon, road signs or other billboards may fall off and be damaged during the trip. Therefore, in the face of heavy rain, what we need to do is to stay at home as much as possible and reduce going out. Another important reason is rainy weather. Usually, the traffic on the road will be blocked, and if you go out, it is likely to pose a threat of congestion.

For the setting of drainage system, many methods have been studied in China since ancient times. In Nanjing, a famous city, we can see that the drainage system left over from ancient times can still be used now. Therefore, strengthening the verification of drainage system is an important method to deal with urban rainstorm waterlogging. At the same time, we should also pay attention to the situation in mountainous areas to avoid the dangers brought by mudslides and landslides.
