Description

Technical Field

[0001] The utility model belongs to the technical field of sponge cities, and in particular relates to a water-permeable pavement structure of a three-lane road cross section road in a sponge city. Background Art

[0002] Sponge city is a new generation of urban stormwater management concept, which means that the city can adapt to environmental changes and deal with natural disasters caused by rainwater like a sponge, and has good elasticity. It can also be called a "water-elastic city". After research, porous concrete with a continuous pore structure made by a specific process can improve the drainage capacity of the road surface, reduce the runoff and scouring damage of the road surface, and the infiltrated rainwater enters the base soil to replenish groundwater resources. At the same time, the porous structure can also enable heat exchange between the atmospheric environment and the soil, which can alleviate the urban heat island effect. The conventional urban road permeable pavement structure obviously cannot fully meet the needs of sponge city construction. Therefore, a new type of environmentally friendly and simple-to-construct urban road permeable pavement structure urgently needs to be proposed by researchers in the engineering technology field. Utility Model Content

[0003] In view of this, the purpose of the utility model is to provide a sponge city three-lane road cross-section road permeable pavement structure to solve the deficiencies in the prior art.

[0004] In order to achieve the above object, the utility model is implemented by the following technical solutions:

[0005] A sponge city three-lane road cross-section permeable pavement structure is provided, in which a motor vehicle lane permeable water-storage pavement structure, a side dividing strip, a non-motor vehicle lane permeable water-storage pavement structure and a sidewalk permeable water-storage pavement structure are arranged in sequence from the road center line to the sidewalk direction, the motor vehicle lane permeable water-storage pavement structure, the non-motor vehicle lane permeable water-storage pavement structure and the sidewalk permeable water-storage pavement structure are all made based on the permeable water-storage pavement structure, a longitudinal seepage drainage pipe is buried at the bottom of the side dividing strip, a transverse water-collecting blind pipe is arranged at the bottom of the permeable water-storage pavement structure, the longitudinal seepage drainage pipe, the transverse water-collecting blind pipe and an external rainwater pipe network are connected to each other, and a bottom waterproof layer is arranged at the bottom of the permeable water-storage pavement structure.

[0006] For example, in the sponge city three-lane road cross-section road permeable pavement structure, the permeable and water-storage pavement structure is made of permeable asphalt concrete, resin permeable concrete or prefabricated permeable bricks.

[0007] As in the three-lane road cross-section permeable pavement structure of the sponge city, the longitudinal drainage pipe is made of a perforated PVC pipe or a reinforced concrete pipe.

[0008] As in the three-lane road cross-section permeable pavement structure of the sponge city, the bottom waterproof layer is made of waterproof geotextile.

[0009] The beneficial effects of the technical solution of the utility model are:

[0010] 1. It can quickly collect rainwater runoff from urban roads, improve the ecological function of roads, and strengthen the "wet and hot" breathing function of cities. It is simple to construct and has good effects on improving the natural environment and human living environment;

[0011] 2. Used in urban road construction, it can improve the water collection and storage capacity of urban roads, greatly reduce road rainwater runoff, and contribute to urban disaster prevention and mitigation;

[0012] 3. This permeable pavement structure provides a new idea for the construction of sponge cities and has good promotion and application value. BRIEF DESCRIPTION OF THE DRAWINGS
