Description

technical field [0001] The present disclosure relates to the technical field of urban rainwater permeable pavement research, in particular to a working simulation device and simulation method for ecological permeable pavement. Background technique [0002] With the development of sponge city construction, permeable pavement has been widely used in cities. Studying the changes in water permeability of different permeable pavement surfaces and different base cushion combinations and the blockage process can optimize the combination and enhance the application value of sponge cities. In order to quickly simulate the application performance of permeable pavement under rainfall conditions, it is necessary to design a device that can simulate the permeable and water purification work of permeable pavement under different rainfall and runoff conditions. [0003] Researchers have used platforms and control methods to simulate rainfall to explore the performance of permeable brick pa...

Problems solved by technology

However, the existing experimental devices either can only simulate the infiltration of a certain height of water flow to measure the water permeability coefficient, and cannot simulate the actual rainfall environment, or can only characterize the impact of permeable pavement through the infiltration rate, so that it is impossible to use The simulation process and results are more realistic. That is to say, there is no way to measure the change of the permeability coefficient and the concentration of suspended solids passing through the permeable pavement for different permeable pavement combinations under the actual simulation of actual rainfall and runoff conditions.
