The shortage of water in cities is serious, the underground water is exploited excessively, the ground subsides, the seawater flows backwards, and the soil salinization is serious. However, in arid cities in the north, the waterlogging is serious, which is in conflict with the water-deficient environment, and the reason is that the water permeability of the soil is poor, rainwater cannot penetrate into the ground bottom, the soil is salinized, and the vegetation is difficult to survive; in addition, the inland cities have serious inland inundation, and partial cities are dedicated to building sponge cities and laying permeable materials, but the effect is little. The urban construction in China is concentrated on ground construction, underground facilities are omitted, and a complete rainwater collection system is not built at the beginning of urban construction. At present, only a surface layer paving material is researched for the construction of a sponge city, and an underground water storage penetration device is not researched and developed, so that rainwater can enter a permeable material but is difficult to enter soil. In addition, in the north, the water permeable materials are easy to freeze and thaw damage because rainwater cannot be drained into soil in time.
