With the continuous increase of sponge city construction projects, different permeable pavement materials are more and more widely used in permeable pavement projects, but in the process of application and promotion, it is found that the strength of permeable bricks is not high, and the bonding between aggregates Not strong, easy to produce particles
The sediment, plant residues and non-point source pollutants carried by rainwater permeating through the permeable material are deposited in the pores of the permeable material layer, resulting in a decrease in its water permeability
Under the action of pedestrians or vehicles, the sand particles deposited on the road surface during wind blowing may be squeezed into the pores of the pavement material layer, which will also lead to a decrease in the water permeability of the permeable pavement, making it impossible for the permeable pavement to fully meet the requirements after a period of time. Water permeability requirements
[0003]
Therefore, it is particularly important to study the performance optimization schemes of different permeable pavement systems. However, at present, they are all aimed at the development of the permeable pavement system performance itself, and the performance testing equipment and methods for how to screen or count reasonable optimization schemes for permeable pavement systems involve less

Abstract
An experimental device and method suitable for performance optimization of a coastal sponge city permeable pavement system are characterized in that: the experimental device comprises a water supply assembly, a permeable paving system assembly and a measuring assembly, wherein the water supply assembly is used for providing simulated rainwater for the permeable paving system assembly; and the permeable paving system assembly is used for treating the simulated rainwater, and outputting signals to the measuring assembly for automatic measurement. The experimental device and the method have the advantage that performance detection and optimization can be carried out on the water permeable paving system which relates to different water permeable bricks and water permeable paving cushion materials with different proportions.
Description
technical field [0001] The invention belongs to the technical field of sponge city construction, and in particular relates to an experimental device and method (detection and optimization method) suitable for performance optimization of a permeable pavement system in a coastal sponge city. Background technique [0002] With the continuous increase of sponge city construction projects, different permeable pavement materials are more and more widely used in permeable pavement projects, but in the process of application and promotion, it is found that the strength of permeable bricks is not high, and the bonding between aggregates Not strong, easy to produce the phenomenon of falling particles. The sediment, plant residues and non-point source pollutants carried by rainwater permeating through the permeable material are deposited in the pores of the permeable material layer, resulting in a decrease in its permeable capacity. Under the action of pedestrians or vehicles, the san...
