The invention relates to the field of urban construction, and specifically to a pavement structure that can discharge accumulated water on the road surface through penetration.

Background technique

With the rapid development of urbanization, cities are becoming increasingly prosperous and filled with high-rise buildings. However, the traditional gray architectural concept and the construction and development model that pursues low-cost and short-term benefits have inevitably caused the destruction of the original ecological environment of urban areas. In the face of increasingly prominent urban flood disasters, the construction of sponge cities is imperative, and comprehensive measures such as infiltration, retention, storage, purification, use, and drainage are adopted to reduce the hazards of rain and flood disasters. However, at this stage, most roads are hard-paved and impermeable. On the surface layer, rainwater accumulates on the road surface on rainy days, making driving dangerous and easily causing traffic accidents. In addition, rainwater on the road surface drains into rivers, causing a waste of fresh water. Therefore, it has become very necessary and urgent to develop a permeable rainwater collection and drainage device.

Detailed ways

The technical solutions in the present invention will be further described below in conjunction with the accompanying drawings and examples.

Example 1:

As shown in Figures 1-4, the present invention proposes a permeable and drainage pavement structure, which includes a hard pavement layer 1, a permeable pavement layer 2 arranged above the hard pavement layer 1, and a permeable pavement layer 2 sandwiched between the hard pavement layer 1 and the hard pavement layer 1. The drainage channels 3 between the permeable pavement layers 2 also include road 4 drainage ditches and reservoirs connected to the drainage channels 3 . In this embodiment, the drainage channel 3 is arranged perpendicular to the forward direction of the road 4. The two ends of the drainage channel 3 are respectively connected to the drainage ditches provided on both sides of the road 4. The drainage ditch is connected to the reservoir for storing the water discharged by the drainage channel 3. The accumulated water can be used for urban greening irrigation, and after purification, it can also be used as sanitary water. It will eventually become part of the sponge city system that integrates penetration, drainage, water storage, and water purification.

The hard pavement layer 1 is a concrete hard pavement layer or a graded gravel hard pavement layer. As the base load-bearing structure of the road 4, it is an impermeable layer. In this embodiment, it is preferably a concrete hard pavement layer; the permeable pavement layer 2 is asphalt. The permeable layer or block permeable brick pavement layer is a load-bearing structure on the surface of the road 4 and allows water to pass through. In this embodiment, it is preferably an asphalt permeable layer. Finally, the accumulated water on the surface of the road 4 passes through the permeable pavement layer 2 and reaches the surface of the hard pavement layer 1 , and further collects into the drainage channel 3 .

The drainage channel 3 of the present invention includes a drainage channel 3 body, a drainage channel 3 cover plate provided on the top of the drainage channel 3 body, and sealing plates 33 provided on both sides of the drainage channel 3 body for fixation. The drainage channel 3 is embedded in the hard pavement layer 1, and the top of the drainage channel 3 is lower than the top surface of the hard pavement layer 1, so that the accumulated water on the surface of the hard pavement layer 1 can flow into the drainage channel 3; the drainage channel 3 The cover plate is a concave plate, and the position of its recessed portion 321 corresponds to the drainage channel 3 body. The recessed portion 321 of the cover plate of the drainage channel 3 is also lower than the surface of the hard pavement layer 1. The cover plate of the drainage channel 3 is in contact with the drainage channel 3. There are also seepage holes 322 at corresponding parts of the body. The cover plate of the drainage channel 3 covers the top of the drainage channel 3 body, which can prevent the roadbed material falling from the permeable pavement layer 2 from entering the drainage channel 3 body and causing obstruction. At the same time, the recessed part 321 is also blocked. It is conducive to the accumulation of water on the surface of the hard pavement layer 1, and finally the accumulated water enters the drainage channel 3 body through the seepage hole 322; the sealing plate 33 is connected to the outward extension of the cover plate of the drainage channel 3, and the sealing plate 33 is also provided with The upwardly inclined inverted teeth 331 cooperate with the concrete in the hard pavement layer 1 to tightly fix the drainage channel 3 in the hard pavement layer 1 .

As shown in Figure 4, the drainage trough 3 bodies can be single grooves, double grooves or multiple grooves to adapt to the rainfall in different areas. When the rainfall is large, if the single trough drainage trough 3 bodies are used, very intensive work is required. The installation is not conducive to improving construction efficiency and saving costs, so double-slot or multi-slot drainage troughs can be used. The shape of the drainage groove 3 body is triangular or semicircular, preferably triangular in this embodiment.

During the construction of the present invention, the hard pavement layer 1 is first laid. After the concrete is laid, and before the concrete hardens, the drainage groove 3 is pressed into the concrete so that it is embedded in the concrete. After the concrete hardens, the drainage groove 3 3 is tightly fixed on the hard pavement layer 1, and finally the permeable pavement layer 2 is laid above the hard pavement layer 1 and the drainage channel 3; it can also be pre-installed before concrete pouring, and the drainage channel 3 and the hard paving road can be pre-installed. The steel frame fixed structure of the surface layer 1 is matched and fixed, and then the grade batching and concrete pouring are carried out, and finally the permeable pavement layer 2 is laid.

Example 2:

As shown in Figure 5, the rest of this embodiment is the same as Embodiment 1, except that a gravel receiving groove 34 is provided next to the drainage tank body 31, and the gravel receiving groove 34 is connected with the drainage tank body. The middle part of one side of 31 is connected, so that one side of the drainage channel body 31 is lower than the other side. Therefore, the drainage channel cover 32 connecting both sides of the drainage channel body 31 is inclined toward the side closer to the gravel receiving channel 34, and the drainage channel 31 is connected in the middle. The top of the cover plate 32 is connected with the gravel receiving groove 34 . In this embodiment, part of the scattered debris in the permeable pavement layer 2 and floating gravel in the hard pavement layer 1 can slide from the top of the inclined drainage channel cover 32 into the gravel receiving groove 34 and will not accumulate in the gravel receiving groove 34 . on the drainage channel cover 32 to avoid clogging the seepage holes 322 on the drainage channel cover 32 after long-term use, ensuring the drainage effect and reducing maintenance time and cost.

Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified. Modifications or equivalent substitutions without departing from the spirit and scope of the technical solution of the present invention shall be included in the scope of the claims of the present invention.
