Taiyuan dispatched a large number of traffic police to flood control and disaster relief.

　　Urban waterlogging is not an unsolvable problem

　　Wang Lumin, dean of the Institute of Urban Planning and Design of Shenzhen University, told Beiqing Daily that there are various reasons for urban waterlogging, but if government departments pay enough attention to pipeline design and urban planning, it can alleviate the flood of urban waterlogging to a considerable extent.

　　Dean Wang introduced that the diameter of the drainage pipeline is designed by calculation according to the long-term situation of rainstorm in a place. This diameter varies according to the location of the city, the specific location of the pipeline in the city and the importance of the location. This may lead to a problem. For example, the drainage pipeline originally located on the edge of the city has a relatively small diameter because of its unimportant position. However, with the continuous increase of urban population and the continuous expansion of urban scale, the place originally located on the edge of the city has gradually become the center of the city. At this time, managers need to constantly adjust to cope with the possible rainstorm disaster.

　　In addition, Dean Wang said that the "hard land" of the city is also one of the reasons why urban waterlogging has intensified in recent years. He said that there were many grasslands and ponds in the original city. When it rained, rainwater would seep into the ground through these places. However, with the development of the city, such places gradually became less and more densely populated, and the ground was covered with relatively hard materials such as cement and asphalt. When the rainstorm came, the rainwater could not seep down, which would "plug up" the urban waterlogging.

　　Dean Wang believes that the solution to urban waterlogging mainly depends on the attitude of the local government to this problem. The drainage pipeline is located underground and can’t be seen at ordinary times, but heavy rain will expose the historical debts of the city. "With a certain investment, the city can solve this problem." This edition/our reporter Qu Chang
