Description

Technical Field

[0001] The utility model relates to the technical field of road construction, in particular to a permeable pavement structure for reconstructing an old road through crushing. Background Art

[0002] Many cities have chosen cement concrete pavement as their road material, mainly because its cost conforms to the principle of economy and can reduce the cost of road construction. However, in use, affected by traffic load, many cement pavements have problems such as potholes, peeling, cracks and misaligned boards. As the service time is extended, the damaged area is also continuously increasing, and the highway system has formed hidden dangers. Therefore, it is necessary to renovate the existing cement pavement. Pavement crushing technology is used in pavement reconstruction projects, especially for cement pavements. Due to the easy maintenance of asphalt pavements, more and more cement pavements that have reached the overhaul period are gradually being transformed into asphalt pavements. However, according to the material characteristics of asphalt pavement, its waterproof performance is better, so when encountering heavy rainfall, rainwater falls on the road surface, which is not easy to penetrate, and the road surface is prone to large-scale water accumulation, which leads to urban waterlogging.

[0020] Example

[0021] The technical solutions in the embodiments of the present utility model will be described clearly and completely below in conjunction with the accompanying drawings.

[0022] like Figure 1-4 As shown, a permeable pavement structure for reconstructing an old road from broken bricks comprises a plurality of pavement brick bodies 1, wherein the pavement brick body 1 comprises an upper brick body 101 and a lower brick body 102, forming a Z-shaped structure, which is convenient for assembly and more stable after assembly. A plurality of base surfaces 2 and a first drainage hole 3 arranged between the base surfaces 2 are arranged on the top of the upper brick body 101, and a water flow slope 4 is arranged between adjacent base surfaces 2. A limiting groove 5 is arranged on the top of one side of the upper brick body 101 close to the lower brick body 102, and a mounting block 6 is arranged on the top of the upper brick body 101 away from the lower brick body 102. A groove 11 is arranged on the top of the mounting block 6, and limiting holes 12 are arranged on the groove 11 and the limiting groove 5, and a limiting column 13 is inserted in the limiting hole 12. The limiting column 13 includes a column head 131 and a column body 132 arranged at the bottom of the column head 131. The diameter of the column head 131 is the same as the diameter of the groove 11, and the diameter of the column body 132 is consistent with the diameter of the limiting hole 12, and the diameter of the column head 131 is larger than the diameter of the column body 132. When the limiting column 13 is inserted to fix two adjacent pavement brick bodies 1, the flatness and beauty of the pavement brick bodies 1 are not affected. The limiting hole 12 on the limiting groove 5 is connected with the drainage groove 10. A plurality of card grooves 7 are opened on the top of the lower brick body 102, and a second drainage hole 8 is arranged inside the card groove 7. A plurality of protrusions 9 adapted to the card groove 7 are arranged at the bottom of the upper brick body 101. The first drainage hole 3 and the second drainage hole 8 are respectively connected with the drainage groove 10 arranged on the inner side of the bottom of the upper brick body 101 and the lower brick body 102.

[0023] The water flow slope 4 includes a slope peak 401 arranged between adjacent base surfaces 2 and a slope body 402 arranged on both sides of the slope peak 401. The interval between adjacent base surfaces 2 is set very small, which is sufficient to drain rainwater. If the interval is too large, it will easily cause pedestrians to feel that the road surface is uneven when stepping on it. The slope valley of the slope body 402 is connected to the top of the first drainage hole 3, and the four adjacent slope bodies 402 together form a funnel-like shape to facilitate the discharge of rainwater.

[0024] During specific use, several pavement brick bodies 1 are spliced ​​together to form a permeable pavement structure. During splicing, the upper brick body 101 is overlapped on the lower brick body 102, and the overlaps are in sequence. The mounting block 6 of the rear upper brick body 101 is installed in the limiting groove 5 of the previous upper brick body 101, and the protrusion 9 of the rear upper brick body 101 is inserted into the card groove 7 of the previous lower brick body 102, and then the limiting column 13 is inserted into the limiting hole 12, and the column head 131 is just stuck in the groove 11, and the top of the column head 131 is at the same horizontal plane as the top of the mounting block 6, which does not affect the overall flatness of the pavement brick body 1. After the splicing is completed, when it rains, rainwater flows along the water slope 4 to the first drainage hole 3, and finally is discharged through the drainage groove 10. Rainwater will inevitably flow into the splicing gap, and finally is discharged through the second drainage hole 8 through the drainage groove 10, reducing road surface water.

[0025] Therefore, the utility model adopts the above-mentioned structure to transform the old road into a permeable pavement structure, which can drain the water on the road surface in time, reduce the phenomenon of water accumulation on the road surface, thereby reducing the possibility of urban waterlogging, is green, environmentally friendly and easy to install.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that they can still modify or replace the technical solution of the utility model with equivalents, and these modifications or equivalent replacements cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of the utility model.
