Description

A new type of urban road permeable pavement structure

technical field

The invention belongs to the technical field of building components, and relates to a permeable pavement structure, in particular to a novel permeable pavement structure for urban roads, which is mainly used for main roads in urban centers.

Background technique

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, the drainage capacity is still limited, and it is difficult to solve the surface runoff problem. , become the main source of rainwater collection, and is also the root cause of urban waterlogging and other problems. Due to the need to have a certain strength requirement, technologies such as permeable concrete and sidewalk permeable pavement cannot be concocted. Therefore, it is necessary to develop a new urban road permeable pavement structure that can meet the bearing capacity requirements and realize rapid water seepage of urban roads, fundamentally solve the flood problem, and promote the further development of my country's "sponge city" construction.

Contents of the invention

In order to overcome the above-mentioned shortcomings of the prior art, the object of the present invention is to provide a new type of urban road permeable pavement structure, which can realize rapid water seepage of urban roads, solve urban waterlogging and other problems and relieve urban The heat island effect, and the use of prefabricated structures can shorten the construction period of urban roads.

In order to achieve the above object, the technical scheme adopted in the present invention is:

A new urban road permeable pavement structure, comprising a structural surface 1, a permeable layer 2, a base 3 and a pile foundation 4, the permeable layer 2 is located below the structural surface 1, and the base 3 is located below the permeable layer 2, characterized in that the The structural surface layer 1 is a prefabricated component formed by the integral pouring of the parallel grid structure and concrete with steel mesh sheets laid on the upper and lower sides. The parallel grid structure is composed of criss-cross stress trusses 6, and the structural surface layer 1 is fixed on the pile foundation 4 On the corbel, there are several trumpet-shaped seepage holes 7 neatly arranged on the structural surface layer 1 .

The connection gap between the structural surface layer 1 and the pile foundation 4 is filled with asphalt 5 .

The stressed truss 6 is a steel truss structure formed by circular steel pipes with a diameter of 3-5cm.

The trumpet-shaped seepage hole 7 has an upper end diameter of 0.5-1 cm, and a lower end diameter of about 3-5 cm.

The permeable layer 2 is formed by compacting crushed stones with a thickness of 40-50 cm. Geotextiles are laid between the permeable layer 2 , the structural surface layer 1 and the base layer 3 .

The base 3 is the undisturbed soil foundation, and several horn-shaped water storage wells 8 are dug in the base 3. The diameter of the upper end of the horn-shaped water storage well 8 is about 0.5m, and the diameter of the lower end is 1.5m. Cloth carries out wall protection, fills up with gravel in the well, and water collecting pipe 9 is buried in the lower end of water storage well 8, and each water storage well 8 is communicated.

Compared with the existing technology, the new urban road permeable pavement structure of the present invention adopts assembly construction during implementation, which can shorten the construction period to a certain extent. On the one hand, the trumpet-shaped seepage holes facilitate the rapid infiltration of rainwater. Preventing the formation of surface runoff effectively solves the problem of urban waterlogging. On the other hand, in hot summer, the trumpet-shaped seepage holes can form a "chimney effect", which is conducive to pumping underground moisture out of the surface, thereby alleviating the urban heat island effect. The trumpet-shaped water storage well can collect and store rainwater, and at the same time, the "chimney effect" can draw geothermal heat out of the ground in winter, thereby solving the problem of snow and ice on the ground. The utility model realizes the "breathing effect" of urban roads and can significantly improve the urban living environment.
