Problems solved by technology

In order to improve the living environment, my country has proposed the concept of "sponge city" construction, and carried out pilot construction in many cities. In view of the problem that surface rainwater is difficult to infiltrate, technical measures such as green belt sinking, sidewalk permeable pavement and permeable concrete have been proposed. , but due to the relatively small area of ​​green belts and sidewalks in the central area of ​​the city, the drainage capacity is still limited, and it is difficult to solve the surface runoff problem. , becoming the main source of rainwater collection, and also the root cause of urban waterlogging and other problems. Due to the need for certain strength requirements, technologies such as permeable concrete and sidewalk permeable pavement cannot be concocted

Embodiment Construction

[0017] The implementation of the present invention will be described in detail below in conjunction with the drawings and examples.

[0018] Such as figure 1 As shown, a new type of urban road permeable pavement structure described in the present invention includes a structural surface layer 1, a permeable layer 2, a base layer 3 and a pile foundation 4, wherein the structural surface layer 1 is prefabricated by integral pouring of a parallel grid structure and concrete Components, steel mesh sheets are laid up and down; the parallel grid structure is composed of criss-cross stress trusses 6, and the stress trusses 6 are steel truss structures formed by circular steel pipes with a diameter of 3-5cm, such as figure 2 As shown; the structural surface 1 is fixed on the corbel of the pile foundation 4, and the connection gap with the pile foundation 4 is filled with asphalt 5; the structural surface 1 has trumpet-shaped seepage holes 7 neatly arranged on the structural surface. ...

Abstract

The invention discloses a novel urban road permeable pavement structure. The novel urban road permeable pavement structure comprises a structural surface layer, a permeable layer, a base layer and pile foundations, wherein the structural surface layer is a prefabricated part formed by a parallel grid structure and concrete by overall pouring, and reinforcing meshes are laid on the upper and lowerparts of the structural surface layer. The structural surface layer is fixed to brackets of the pile foundations, and joint gaps between the structural surface layer and the pile foundations are filled with asphalt. The structural surface layer is provided with neatly arranged trumpet-shaped water seepage holes which are convenient to timely discharge rainwater into the permeable layer formed by compacting gravel. Trumpet-shaped water storage wells are dug in the base layer and are connected through a water collecting pipe, reinforcing meshes and geotextiles are used for wall protection, and at the same time, the wells are filled with gravel. The trumpet-shaped water seepage holes and the water storage wells form a chimney effect to facilitate circulation of air humidity and temperature. The novel urban road permeable pavement structure can effectively solve the urban internal waterlogging problem while alleviating the urban heat island effect, is of great significance for improving the living environment, and can promote the further development of ''sponge city'' construction of China.

Description

technical field [0001] The invention belongs to the technical field of building components, and relates to a permeable pavement structure, in particular to a permeable pavement structure for urban roads, which is mainly used for main roads in urban centers. Background technique [0002] With the continuous advancement of the urbanization process, the urban land has been surrounded by reinforced concrete hardening, and the surface water is difficult to infiltrate, resulting in the rapid formation of surface runoff. serious. In order to improve the living environment, my country has proposed the concept of "sponge city" construction, and carried out pilot construction in many cities. In view of the problem that surface rainwater is difficult to infiltrate, technical measures such as green belt sinking, sidewalk permeable pavement and permeable concrete have been proposed. , but due to the relatively small area of ​​green belts and sidewalks in the central area of ​​the city, t...
