Description

Technical Field

[0001] This utility model relates to the field of permeable pavement structure technology, specifically an assembled permeable road pavement structure. Background Technology

[0002] Permeable bricks are paving bricks used for paving. On one hand, permeable bricks have excellent water and air permeability, allowing rainwater to quickly infiltrate the ground, replenishing soil and groundwater, maintaining soil moisture, and improving the living conditions of urban ground plants and soil microorganisms. On the other hand, permeable bricks can absorb moisture and heat, regulating the temperature and humidity of local surface spaces, playing a significant role in regulating urban microclimates and mitigating the urban heat island effect. Currently, permeable roads are mostly constructed using on-site paving, which causes environmental pollution during urban road construction, has a long construction period, and disrupts road traffic. Our company has now developed a low-carbon, modular permeable road paving structure, which is prefabricated in a factory and assembled on-site, making construction quick and convenient, with a short construction period. During construction, it can greatly reduce the use of machinery, materials, and labor, achieving low-carbon construction, that is, maximizing resource conservation and minimizing energy consumption.

[0003] In existing technologies, such as the one proposed in CN218175457U, a low-carbon, modular permeable pavement structure is described. This technical solution discloses a low-carbon, modular permeable pavement structure, including a first permeable brick body, a second permeable brick body, and reinforcing bars. By assembling the road structure on-site, construction is quick and convenient, achieving low-carbon construction. The road structure, from bottom to top, consists of: a crushed stone layer, an interlocking permeable stabilizing layer, and a permeable surface layer. The porous structure between layers is permeable, allowing rainwater to seep through both the pores and the gaps between the bricks, resulting in excellent permeability. Furthermore, the interlocking permeable stabilizing layer and the crushed stone layer have numerous pore spaces, enabling the infiltration and storage of significant amounts of water. Through rainwater evaporation, the surrounding microclimate can be improved. In the construction of sponge cities and eco-cities, this structure enhances the permeability, storage, and purification of rainwater. It can be widely applied to municipal sidewalks, squares, parks, residential roads, and riverbank protection, increasing rainwater infiltration and improving the regional ecological environment.

[0004] However, after the existing permeable bricks are assembled, the two adjacent permeable bricks still need to be reinforced by removing reinforcing bars. This makes the disassembly and assembly of permeable bricks quite troublesome. When permeable bricks are damaged after long-term use, it is difficult for workers to replace the damaged permeable bricks individually.

[0005] To address the aforementioned issues, this application proposes an assembled permeable road paving structure. Utility Model Content

[0006] This utility model aims to provide an assembled permeable road paving structure, mainly to solve the problem that the disassembly and assembly of existing permeable bricks is relatively troublesome, and that it is difficult for workers to replace damaged permeable bricks individually when they are damaged after long-term use.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0008] An assembled permeable pavement structure includes a permeable brick body, a symmetrical locking block fixedly connected to one side of the permeable brick body, a locking groove matching the locking block on the side of the permeable brick body away from the locking block, a plurality of positioning pins fixedly connected to the bottom of the inner wall of the locking groove, and the positioning pins are distributed in a linear array at equal intervals inside the locking groove, the locking block is provided with a positioning hole matching the positioning pin, and a limit component is provided at the upper end of the positioning pin.

[0009] The working principle and beneficial effects of this utility model:

[0010] 1. Working Principle: When laying the permeable brick body, first lay the first permeable brick body, then place the second permeable brick body on one side of the first permeable brick body, and ensure that the locking block on the second permeable brick body engages with the locking groove on the first permeable brick body. Simultaneously, align the positioning pin inside the locking groove with the positioning hole on the locking block. Then, the two permeable brick bodies are fixed by the limiting component, thus completing the assembly of two adjacent permeable bricks. Similarly, after assembling all the permeable brick bodies, It can complete the laying of permeable bricks (the road structure from bottom to top is: crushed stone layer, interlocking permeable stabilizing layer, and permeable surface layer. The pore structure between the layers is permeable, and rainwater can simultaneously seep into the pore structure and permeate through the gaps between the bricks on the road surface, resulting in good permeability. In addition, the interlocking permeable stabilizing layer and the crushed stone layer have a lot of pore space, which can permeate and store a lot of water. Through the evaporation of rainwater, it can improve the surrounding microclimate). The part in parentheses is the prior art, which has not been described in detail in this application.

[0011] 2. Beneficial effects: When assembling the permeable brick body, the locking block on one permeable brick body is inserted into the locking groove on another permeable brick body, and the positioning pin inside the locking groove is inserted into the corresponding positioning hole on the locking block. Then, the two permeable brick bodies are fixed by the limiting component, thus completing the assembly of two adjacent permeable bricks. This not only makes the two adjacent permeable brick bodies more stable after assembly, but also makes the assembly and disassembly of the permeable brick bodies more convenient, thereby facilitating the maintenance or replacement of the permeable brick bodies by the staff.

[0012] Preferably, the limiting component includes a threaded hole at the upper end of the positioning pin, a circular groove at the upper end of the positioning hole on the locking block, a locking bolt connected to the threaded hole, and a nut fixedly connected to the upper end of the locking bolt extending into the circular groove. After the locking block on one permeable brick body is inserted into the slot on another permeable brick body, and the positioning pin inside the slot is inserted into the corresponding positioning hole on the locking block, the locking bolt is installed into the threaded hole on the positioning pin and tightened using a tool, thereby fixing the two permeable brick bodies.

[0013] Preferably, a positioning block is fixedly connected to the bottom of the inner wall of the slot, and a positioning groove matching the positioning block is opened at the bottom of the slot. When assembling the permeable brick body, the positioning block inside the slot needs to be inserted into the positioning groove at the bottom of the slot at the same time. This can play a better positioning role for the permeable brick body, thereby making the permeable brick body more stable after assembly.

[0014] Preferably, the top of the nut has an internal hexagonal hole, and the upper surface of the nut is not higher than the top of the locking block. After the locking bolt is installed, the upper surface of the nut is not higher than the top of the locking block, so that it will not protrude and cause wear. The internal hexagonal hole on the top of the nut makes it easier and less strenuous for workers to turn the nut with a hex wrench, and can effectively reduce the possibility of slippage.

[0015] Preferably, the corners on both sides of the bottom of the inner wall of the positioning groove are chamfered. By setting the corners on both sides of the bottom of the inner wall of the positioning groove as chamfered, it is easier for the positioning block to be inserted into the positioning groove, thereby making the assembly of the permeable brick body easier.

[0016] Preferably, a rubber plug is fitted inside the circular groove above the nut. After the permeable brick body is assembled, the rubber plug is fitted inside the circular groove. This can effectively prevent dust from entering the internal hexagonal hole on the nut. When it is necessary to disassemble the permeable brick body, use a tool to pry out the rubber plug and then remove the locking bolt to disassemble the permeable brick body.

[0017] Preferably, all corners of the permeable brick body are rounded. By making all corners of the permeable brick body rounded, it can effectively prevent workers from being scratched by the corners of the permeable brick body when disassembling and assembling it. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 A modular permeable pavement structure includes a permeable brick body 1. The corners of the permeable brick body 1 are rounded to effectively prevent workers from being scratched by the corners during assembly and disassembly. Symmetrical locking blocks 2 are fixedly connected to one side of the permeable brick body 1. A matching slot 3 is provided on the side of the permeable brick body 1 away from the locking blocks 2. When assembling the permeable brick body 1, the locking blocks 2 on one permeable brick body 1 are inserted into the slot 3 on another permeable brick body 1. Multiple positioning pins 4 are fixedly connected to the bottom of the inner wall of the slot 3, and the positioning pins 4 are linearly arrayed and equidistantly distributed inside the slot 3. The locking blocks 2 have positioning holes 5 that match the positioning pins 4. A positioning block 9 is fixedly connected to the bottom of the inner wall of the slot 3, and the bottom of the locking blocks 2 has a matching hole 5. The positioning groove 10 and the positioning pin 4 inside the slot 3 are inserted into the corresponding positioning hole 5 on the card block 2, and the positioning block 9 is inserted into the positioning groove 10. This can play a good positioning role for the permeable brick body 1, so that the permeable brick body 1 is more stable after assembly. The corners on both sides of the bottom of the inner wall of the positioning groove 10 are chamfered, which makes it easier for the positioning block 9 to be inserted into the positioning groove 10, thus making the assembly of the permeable brick body 1 more convenient. The upper end of the positioning pin 4 is provided with a limit component. By fixing the two permeable brick bodies 1 through the limit component, the assembly of two adjacent permeable bricks can be completed. This not only makes the assembly of two adjacent permeable brick bodies 1 more stable, but also makes the disassembly and assembly of the permeable brick body 1 more convenient, thus making it easier for workers to repair or replace the permeable brick body 1.

[0025] like Figure 3 and Figure 4 As shown, the limiting component includes a threaded hole 6 at the upper end of the positioning pin 4, a circular groove 12 at the upper end of the positioning hole 5 on the locking block 2, a locking bolt 7 threadedly connected inside the threaded hole 6, a nut 8 fixedly connected to the upper end of the locking bolt 7 inside the circular groove 12, an internal hexagonal hole 11 at the top of the nut 8, and the upper end face of the nut 8 not higher than the top of the locking block 2, and a rubber plug 13 snapped into the circular groove 12 above the nut 8, so that the locking block 2 on one permeable brick body 1 can be snapped into another permeable brick body. After inserting the positioning pin 4 inside the slot 3 on the card block 1 into the corresponding positioning hole 5 on the card block 2, use a tool to install the locking bolt 7 into the threaded hole 6 on the positioning pin 4 and tighten it. Then, snap the rubber plug 13 into the inside of the round groove 12 to fix the two permeable brick bodies 1. When it is necessary to disassemble the permeable brick body 1, use a tool to pry out the rubber plug 13 and then remove the locking bolt 7 to disassemble the permeable brick body 1. This makes the disassembly and assembly of the permeable brick body 1 more convenient.

[0026] As can be seen from the above, the specific embodiments of this utility model are as follows:

[0027] When laying the permeable brick body 1, first lay the first permeable brick body 1, then place the second permeable brick body 1 on one side of the first permeable brick body 1, and make the locking block 2 on the second permeable brick body 1 engage with the locking groove 3 on the first permeable brick body 1. At the same time, align the positioning pin 4 inside the locking groove 3 with the positioning hole 5 on the locking block 2, and let the positioning block 9 engage with the positioning groove 10. Use a tool to install the locking bolt 7 into the threaded hole 6 on the positioning pin 4 and tighten it. Then, attach the rubber plug 13 into the round groove 12 to fix the two permeable brick bodies 1. Similarly, after assembling all the permeable brick bodies 1, the laying of permeable bricks is completed. (The road structure from bottom to top is: gravel layer, interlocking permeable stabilizing layer, permeable layer...) The surface layer has a porous structure between layers, allowing rainwater to seep through both the porous structure and the gaps between the bricks, resulting in good permeability. Furthermore, the interlocking permeable stabilizing layer and the gravel layer have numerous pore spaces, enabling them to infiltrate and store a significant amount of water. Through rainwater evaporation, this can improve the surrounding microclimate. (The text in parentheses refers to existing technology, which is not elaborated upon in this application.) When disassembling the permeable brick body 1, tools are used to pry out the rubber plug 13, and then the locking bolt 7 is removed. This allows for the disassembly of the permeable brick body 1. This not only ensures high stability after assembly of two adjacent permeable brick bodies 1 but also facilitates the assembly and disassembly of the permeable brick body 1, making it easier for workers to repair or replace it.

[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
