The problem of urban waterlogging in China generally exists, large-area water accumulation on urban road surfaces can be caused by strong rainfall or continuous rainfall, and even general rainfall can form a water surface with a certain area at a low-lying position on the road surfaces. The reason for causing the problem of surface water accumulation is mainly as follows: the urban water-tight hardened surface is too much, the water outlet on the road surface is too little, and a large amount of rainwater is mixed with sundries such as branches and leaves to be gathered together when raining, so that the water outlet is blocked to influence the water drainage speed; secondly, the diameter of the drainage pipe is small, rainwater and sewage are not shunted, and a large amount of rainwater is flushed into the drainage pipe in a short time to exceed the drainage capacity of the drainage pipe by using the same drainage system; thirdly, the terrain in the city is high or low, the low-lying areas of the terrain need to bear the drainage of the areas with higher terrain, and a large amount of transferred rainwater exceeds the water delivery capacity of pipelines in the low-lying areas of the terrain. To the problem of road ponding, the current solution is to reform transform city sewer pipe net, increase the drain pipe diameter. However, the improvement measures consume a great deal of manpower and material resources, and meanwhile, clean rainwater cannot supplement underground water, so that the urban underground water level is reduced, and a road surface collapse event happens occasionally.
