Problems solved by technology

[0003] At present, most of the domestic urban construction uses manual labor to test the feasibility of regional construction. For example, due to the impact of changes in working conditions in various areas on the physical and chemical properties of the soil, this treatment method requires a lot of labor and the construction is destructive. Construction trials require huge investment and high operating costs. At the same time, the original activity of the regional environment and soil has been destroyed by multiple constructions, and the water quality life has been greatly reduced. At the same time, the monitoring methods for soil physical and chemical properties are complicated and time-consuming, and the data collection time interval is large. It is impossible to comprehensively monitor the instantaneous changes of the physical and chemical properties of the matrix inside the underground infiltration system
