Description

Permeable pavement

Technical Field

The utility model relates to a permeable pavement road surface belongs to road engineering technical field.

Background

With the development of urbanization, various construction lands are gradually increased, the former natural soil surface is replaced by the waterproof hardened ground in the city, the original natural ecological environment is changed, the rainfall, evaporation and rainwater runoff converging process are influenced, and the ecological artificial desert is formed. The addition of the hardened pavement reduces the time for collecting rainwater and increases the peak flow of rainwater. In addition, the urban rainfall surface runoff nowadays becomes an important pollution source for the urban water environment quality. During the formation of rainfall runoff, a lot of pollutants such as SS, COD, organic nutrient substances, grease and the like are generated by scouring. The pollutants enter rivers and lakes along with runoff, cause larger-area water body pollution and become second-most non-point source pollution next to agricultural non-point source pollution. Therefore, the problems of urban rainstorm waterlogging and surface runoff pollution become one of the major problems restricting the sustainable development of urbanization. The urban inland inundation and water pollution problem can not be solved by utilizing engineering measures and engineering construction such as municipal drainage systems, regulation and storage pools and the like, so that large capital is consumed, and precious urban land is occupied. In future urban planning, there is an urgent need to take into account sustainable urban drainage systems.

The pavement can be divided into two basic forms of permeable pavement and impermeable pavement. The traditional waterproof pavement attaches more importance to the durability and the firmness of the pavement ground, but the closed pavement of the type blocks natural rainfall from infiltrating back to the base soil and cannot supply underground water, so that the backflow of an urban underground water system is reduced, the biological environment of urban surface soil is seriously damaged, and a series of urban hydrological problems are brought.

The permeable pavement refers to a pavement form that the material with good water permeability and large porosity is selected to be paved on the road on the basis of not influencing the strength and the durability of the road, so that rainwater flows through a pavement layer to permeate into the ground or is discharged to a rainwater pipe, the pavement form can increase the smooth permeation of the rainwater for pavement, and part of water is stored in the pavement layer structure, thereby achieving the purpose of reducing surface runoff. Common material structures are concrete bricks with reserved or net-shaped structures forming gaps, infiltration of rainwater runoff is achieved by filling soil, plants, gravel, broken stones and the like into the gaps, and the concrete bricks are mostly used on the ground such as driveways, sidewalks, fire-fighting special channels and parking lots. Foreign scholars roughly divide the permeable concrete pavements into three types, and according to the difference of the permeable mode and the water storage capacity of the concrete pavements, the three types of pavements are as follows: the surface layer is pervious concrete (containing blocks) or asphalt concrete surface layer; graded broken stones, water-permeable pavement of a water storage base layer, and water-permeable concrete pavement of a surface layer, and water permeation or water seepage per se is realized by utilizing gaps; graded broken stones, permeable pavement of a water storage base layer and impermeable concrete pavement, and water permeation or self water permeation is realized by utilizing gaps; graded broken stones and no special permeable pavement of the water storage base layer.

The research concept of the permeable pavement and the previous pavement method is very different when rainwater is treated. The conventional pavement method is watertight, and rainwater can be blocked to the outside of a pavement structure layer and flows into drainage structures on two sides of a road. However, the permeable pavement is a better permeability of reasonably using the permeable material, and rainwater is stored in a gap structure of the permeable pavement material for a short time. The permeable pavement has a good permeation function and a good moisture preservation function, meets the use requirements of people on traffic pavements, relieves the damage of hardened pavements to ecological environments, and well maintains the living space of organisms below the permeable pavement.
