Abstract

The utility model discloses a permeable pavement structure for residential communities, which sequentially comprises a plain soil rammed layer, a broken stone cushion layer, a fine stone concrete layer, a dry hard cement mortar layer and a plurality of permeable bricks which are horizontally paved from bottom to top, wherein two adjacent permeable bricks are spliced together by adopting a mortise and tenon structure. The permeable pavement structure for the residential community, provided by the utility model, adopts the permeable bricks with the mortise and tenon structure, so that the permeable pavement structure not only has a good permeable effect and relieves the pressure of a drainage system, but also can effectively avoid loosening of the bricks, prevent the road from unevenly settling and prolong the service life of the road.

Description

Water-permeable pavement structure for residential district Technical Field The utility model relates to a permeable pavement structure, in particular to a permeable pavement structure for residential communities. Background Sponge city construction has achieved significant success in multiple pilot cities. In the future, with the deep promotion of ecological civilization construction and the implementation of a double-carbon target, sponge city construction becomes an important development direction of novel urbanization, the technical system is continuously perfected, the application range is continuously expanded, and important support is provided for construction livability, toughness and smart cities. The sponge city construction concept is developed, and the core of the sponge city construction concept is to construct virtuous circle of a city water ecological system through various technical means such as seepage, stagnation, storage, purification, use, drainage and the like. The novel city development mode not only can effectively relieve the problem of urban waterlogging and improve the utilization efficiency of water resources, but also can improve the urban ecological environment and promote the harmonious symbiosis of people and nature. The water permeable brick is often used in sponge city construction as one of the water permeable pavement. The permeable bricks are used for quickly infiltrating rainwater through pore structures, so that surface runoff is reduced, and the pressure of a drainage system is relieved. The current water permeable brick mainly has the following problems: 1. After a period of time, people or vehicles are easy to loosen, and the passing of the people or vehicles is influenced; 2. drainage ditches are arranged on two sides of a road or directly discharged into green belts on two sides of a general district water permeable brick road, but in a weather period with large rainwater, the rainwater cannot be discharged in time, and the rainwater is mixed with dust on the surface of the brick to easily block the pores of the water permeable brick, so that the water permeable function is reduced. Disclosure of utility model The utility model aims to solve the technical problem of providing a permeable pavement structure for residential communities, which not only has good permeable effect and relieves the pressure of a drainage system, but also can effectively avoid loosening of bricks, prevent uneven settlement of roads and prolong the service life of the roads. The technical scheme adopted by the utility model for solving the technical problems is to provide a permeable pavement structure for residential communities, which sequentially comprises a plain soil rammed layer, a broken stone cushion layer, a fine stone concrete layer, a dry hard cement mortar layer and a plurality of permeable bricks which are horizontally paved from bottom to top, wherein two adjacent permeable bricks are spliced together by adopting a mortise and tenon structure. Further, a linear drainage ditch is formed between the water permeable bricks, a drainage ditch cover plate is arranged above the linear drainage ditch, and the lower part of the linear drainage ditch penetrates through and extends to the broken stone cushion layer and lays a fine stone concrete foundation layer. Further, the strength grade of the fine stone concrete foundation layer is C20-C30. Further, the thickness of the broken stone cushion layer is 80-150 mm. Further, the thickness of the fine stone concrete layer is 100-180 mm, and the concrete strength grade is C25-C35. Further, the thickness of the dry and hard cement mortar layer is 30mm. Compared with the prior art, the permeable pavement structure for the residential community has the advantages that the permeable bricks with the mortise and tenon structure have good permeable effect, the pressure of a drainage system is relieved, loosening of the bricks can be effectively avoided, the permeable bricks are fixedly adhered and permeable pavement by adopting the dry and hard cement mortar layer, and the fine stone concrete layer and the broken stone cushion layer are arranged below the dry and hard cement mortar layer, so that leveling is achieved, the strength of a foundation is guaranteed, uneven settlement of a road is prevented, and the service life of the road is prolonged. Drawings FIG. 1 is a schematic diagram of a permeable pavement structure for residential communities according to the present utility model; Fig. 2 is a schematic diagram showing the splicing of two adjacent water permeable bricks in the water permeable pavement structure of the present utility model. The marks in the figure: 1-plain soil ramming layer, 2-broken stone cushion layer, 3-fine stone concrete layer, 4-dry hard cement mortar layer, 5-water permeable bricks, 6-linear drainage ditches, 7-drainage ditch cover plate and 8-fine stone concrete foundation layer.
