Description

Technical Field

[0001] This utility model relates to the field of permeable pavement structure technology, specifically a multi-layer composite permeable pavement structure. Background Technology

[0002] Permeable pavement, as an effective sponge infrastructure, is widely used in sidewalks, pedestrian streets, garden paths, and other roads without motor vehicle loads, as well as roads, squares, and parking lots with light load requirements. However, due to its large-pore structure, the strength of each layer is weak, limiting its application in medium- and heavy-load roads. An existing patent, CN217052909U, describes a permeable composite pavement overlay structure. This structure includes a permeable cement concrete layer laid on top of a base course and a subgrade. A connecting layer is placed above the permeable cement concrete layer, and a permeable asphalt concrete surface layer is laid on top of the connecting layer. The permeable asphalt concrete surface layer is connected to the permeable cement concrete layer through the connecting layer. This device improves the bonding effect between the permeable cement concrete layer and the permeable asphalt concrete surface layer, providing sufficient support, enhancing driving comfort, and improving permeability and drainage. Using the permeable asphalt concrete surface layer reduces material usage and saves resources.

[0003] Regarding the aforementioned technologies, the inventors believe that the following defects exist: although they can be reinforced with concrete layers during use, the lack of an effective reinforcement structure makes them prone to displacement due to vehicle pressure after the paving is completed. Therefore, we propose a multi-layer composite permeable pavement structure to solve the above-mentioned problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a multi-layer composite permeable paving structure, which solves the problem that existing paving blocks are prone to displacement due to vehicle traffic after installation because of the lack of effective cultivation and reinforcement structures.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a multi-layer composite permeable pavement structure, including a first crushed stone layer, with a permeable pipe fixedly connected inside the first crushed stone layer. There are two permeable pipes, which are fixedly connected in a straight array to the front and rear sides inside the first crushed stone layer. A first geotextile is laid on the top of the first crushed stone layer, and a soil base layer is covered on the top of the first geotextile. A second geotextile is laid on the top of the soil base layer.

[0006] Preferably, a leveling layer is laid on the top of the second geotextile, and a mixing layer is laid on the top of the leveling layer.

[0007] Preferably, the top of the mixed layer is covered with bricks, and drainage grooves are formed on the top surface of the bricks.

[0008] Preferably, the drainage channel is a ring structure, and the drainage channel and the bricks together form a drainage structure.

[0009] Preferably, the brick body has four drainage holes inside, which are located at the four corners of the brick body.

[0010] Preferably, a mounting base is fixedly connected inside the drain hole, and the mounting base has insertion holes arranged in a ring array inside.

[0011] Preferably, an installation ring is installed inside the drain hole. The installation ring has a ring structure, and a rod is fixedly connected in a ring array on the bottom end face of the installation ring. The rod has a cylindrical structure and matches the insertion hole opened in the mounting base.

[0012] Beneficial effects

[0013] This utility model provides a multi-layer composite permeable pavement structure. Compared with the prior art, it has the following advantages:

[0014] This multi-layer composite permeable pavement structure features drainage channels on the top surface of the bricks. These channels allow rainwater to drain quickly after multiple bricks are laid, thus preventing slippage.

[0015] This multi-layered composite permeable paving structure features drainage holes located at the four corners of the brick body. The interior of the drainage holes can be assembled using embedded mounting rings. These mounting rings can reinforce the grass seeds planted inside the drainage holes and provide overall reinforcement and support to the brick body, thus achieving a more practical purpose.

A second geotextile 104 is laid on the top of the soil base layer 103.

[0025] By laying a first geotextile 102 on top of the first crushed stone layer 1, the first crushed stone layer 1 can be reinforced as a whole when in use.

[0026] See Figure 1 , Figure 2 The top of the second geotextile 104 is covered with a leveling layer 105, and the top of the leveling layer 105 is covered with a mixed layer 106.

[0027] By laying a mixed layer 106 on top of the leveling layer 105, the mixed layer 106 can be used as a concrete structure to achieve the purpose of stable support.

The plug rod 303 is a cylindrical structure, and the plug rod 303 matches the plug hole 301 opened in the mounting base 3.

[0037] By fixing a plug rod 303 to the bottom end face of the mounting ring 302, the mounting ring 302 can be quickly connected and installed during use.
