Abstract
Description
Technical Field
[0001] This utility model relates to the field of paving stone technology, specifically to an ecological paving stone with a drainage structure. Background Technology
[0002] Eco-friendly paving stones are a new type of environmentally friendly ground paving material made from recycled resources such as natural stone powder and clay through processes such as high-temperature calcination and high-pressure molding. They not only realistically reproduce the texture and feel of natural stone, but also have excellent anti-slip, wear-resistant, pressure-resistant, and flexural-resistant properties. They are easy to construct and maintain, combining decorative and practical functions, and conform to the environmental protection concept of sustainable development. With the acceleration of urbanization, eco-friendly paving stones are being used more and more widely in fields such as garden landscapes and urban roads.
[0003] In the prior art, Chinese patent CN222205899U discloses an outdoor quick-installation eco-friendly paving stone, including a paving stone base and quick-installation connectors. The paving stone base has a connecting groove on its side that matches the quick-installation connectors. Each side of the bottom surface of the paving stone base has an inwardly tapered chamfer. The quick-installation connectors include a first connector and a second connector, which are detachably connected. When two paving stone bases are spliced, the first connector is simultaneously inserted into the connecting grooves of the two paving stones, and the second connector contacts the chamfer of the two paving stone bases. The quick-installation connectors enable the rapid installation of multiple paving stone bases, improving the flexibility of paving and adapting to the installation requirements of different road surfaces. Once fixed, the stones are less prone to loosening, improving installation stability.
[0004] Based on the above information, existing eco-friendly paving stones have certain shortcomings in practical use. Since paving stones are usually used outdoors and are exposed to wind and rain for a long time, their drainage function is difficult to meet the actual needs, resulting in serious water accumulation on the surface of the paving stones, and the water cannot be drained in time. In addition, when pedestrians step on them, water will splash up, which not only affects the passage experience but also poses a safety hazard. Therefore, we propose an eco-friendly paving stone with a drainage structure. Utility Model Content
[0005] The purpose of this utility model is to provide an ecological paving stone with a drainage structure to solve the problems mentioned in the background art. The existing ecological paving stones have certain defects in actual use. Since paving stones are usually used in outdoor scenes and are exposed to wind and rain for a long time, their drainage function is difficult to meet the actual needs, resulting in serious water accumulation on the surface of the paving stones. The water cannot be drained in time. In addition, when pedestrians step on them, water will splash up, which not only affects the passage experience but also poses a safety hazard.
[0006] To achieve the above objectives, this utility model provides the following technical solution: an ecological paving stone with a drainage structure, comprising a base layer, a drainage layer on top of the base layer, and a buffer layer at the bottom of the base layer, wherein the drainage layer has a drainage structure inside, the drainage structure comprising a first guide channel, a second guide channel and a drainage channel opened on the outer wall of the drainage layer, a drainage groove and a drainage hole opened inside the drainage layer, and an anti-slip texture on the outer wall of the drainage layer.
[0007] Furthermore, the first guide channel has a rectangular cross-section and is evenly distributed on the top outer wall of the drainage layer, and the length of the first guide channel is less than the width of the drainage layer.
[0008] Furthermore, the second guide channel is perpendicular to the first guide channel, and the length of the second guide channel is less than the length of the drainage layer. The second guide channels are evenly distributed on the top outer wall of the drainage layer. The bottom of the second guide channel is inclined, and the horizontal plane at the center of the second guide channel is higher than the horizontal plane at both ends.
[0009] Furthermore, the drainage channel has a "U" shaped cross-section, and the width of the drainage channel is the same as the length of the first guide channel, and the length of the drainage channel is the same as the length of the second guide channel. The drainage channel is connected to both the first guide channel and the second guide channel.
[0010] Furthermore, the drainage trough has a "U" shaped cross-section, and the top of the drainage trough is connected to the bottom of the drainage channel. The cross-section formed by the drainage trough and the drainage channel is L-shaped.
[0011] Furthermore, the inner wall of the drainage trough is provided with drainage holes, which are evenly distributed and located at the bottom of the drainage trough away from the drainage channel. The drainage holes are also provided on the outer walls of the drainage layer and the foundation layer, with the top of the drainage holes communicating with the drainage trough and the bottom of the drainage holes penetrating the foundation layer.
[0012] Furthermore, the cross-section of the foundation layer is convex, the bottom of the drainage layer is provided with an installation groove, and the inner wall of the installation groove is in contact with the top of the foundation layer. The inner wall of the installation groove is provided with a limiting protrusion distributed in an array. The top of the foundation layer is provided with a limiting groove, and the inner wall of the limiting groove is in contact with the outer wall of the limiting protrusion. The drainage layer and the foundation layer are fixed by bonding.
[0013] Furthermore, the buffer layer is made of multi-layer elastic mesh material, and the top of the buffer layer is provided with fixed protrusions arranged in an array. The bottom of the base layer is provided with a fixed groove, and the inner wall of the fixed groove is in contact with the outer wall of the fixed protrusion.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] 1. This eco-friendly paving stone with a drainage structure, through a three-dimensional drainage network composed of a first diversion channel, a second diversion channel, a drainage channel, a drainage trough, and a drainage hole, can quickly and effectively divert and discharge accumulated water on the surface of the paving stone. The design of the first and second diversion channels being perpendicular to each other, combined with their specific dimensions and inclination angles, can collect rainwater from the surface of the paving stone in all directions, allowing the rainwater to quickly converge into the drainage channel, and then be discharged through the drainage trough and drainage hole, significantly improving drainage efficiency, preventing water accumulation on the surface of the paving stone, and solving the problem of poor drainage in existing technologies.
[0016] 2. The base layer and drainage layer adopt a convex-shaped installation groove, limiting protrusion and limiting groove connection method, which not only enhances the connection stability between the various parts of the paving stone and prevents loosening and displacement during use, but also facilitates disassembly, repair or replacement when some parts of the structure are damaged, reducing the later maintenance cost and difficulty.
[0017] 3. The anti-slip texture on the outer wall of the drainage layer effectively increases the friction of the paving stone surface. Even in waterlogged conditions, it provides a good anti-slip effect for pedestrians, reducing the risk of slipping and ensuring pedestrian safety. At the same time, the buffer layer uses multi-layer elastic mesh material and is connected to the base stone layer through fixed protrusions. It can effectively buffer the impact of pedestrians stepping on it or vehicles running over it, reducing damage to the paving stones and extending their service life. Even if the paving stones break, the buffer layer can effectively prevent the paving stones from scattering and being lost due to breakage, thus preventing the road surface from becoming uneven. It can also alleviate water splashing to a certain extent and improve the travel experience.
[0018] 4. The L-shaped cross-section design of the drainage trough and drainage channel, combined with the reasonable layout of the drainage holes, can effectively prevent debris from entering the drainage system during the drainage process, reduce the possibility of drainage channel blockage, ensure the long-term stable operation of the drainage structure, and to a certain extent avoid water splashing from the drainage holes, further improving drainage performance and optimizing the use effect of the paving stones.

[0028] 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.
[0029] Example 1: Please refer to Figures 1-4 The present invention provides the following technical solution: an ecological paving stone with a drainage structure, including a base layer 1, a drainage layer 2 on the top of the base layer 1, and a buffer layer 3 at the bottom of the base layer 1. The drainage layer 2 is provided with a drainage structure inside, the drainage structure including a first guide channel 401, a second guide channel 402 and a drainage channel 5 opened on the outer wall of the drainage layer 2, and a drainage groove 6 and a drainage hole 7 opened inside the drainage layer 2.
[0030] like Figures 1-3 As shown, the first guide channel 401 has a rectangular cross-section and is evenly distributed on the top outer wall of the drainage layer 2. The length of the first guide channel 401 is less than the width of the drainage layer 2. The second guide channel 402 is perpendicular to the first guide channel 401 and is less than the length of the drainage layer 2. The second guide channel 402 is evenly distributed on the top outer wall of the drainage layer 2. The bottom of the second guide channel 402 is inclined, and the horizontal plane at the center of the second guide channel 402 is higher than the horizontal planes at both ends.
[0031] like Figures 1-4As shown in the figure, the cross-section of the drainage channel 5 is designed in a "return" shape, and the width of the drainage channel 5 is the same as the length of the first diversion groove 401, and the length of the drainage channel 5 is the same as the length of the second diversion groove 402. The drainage channel 5 is connected to both the first diversion groove 401 and the second diversion groove 402. The cross-section of the drainage trough 6 is designed in a "return" shape, and the top of the drainage trough 6 is connected to the bottom of the drainage channel 5. The cross-section formed by the drainage trough 6 and the drainage channel 5 is designed in an L shape. Drainage holes 7 are provided on the inner wall of the drainage trough 6, and the drainage holes 7 are evenly distributed. The drainage holes 7 are located at one end of the bottom of the drainage trough 6 far from the drainage channel 5. The drainage holes 7 are provided on both the drainage layer 2 and the outer wall of the foundation layer 1, and the top of the drainage holes 7 is connected to the drainage trough 6, and the bottom of the drainage holes 7 penetrates through the foundation layer 1.
[0032] When rainwater falls on the surface of the paving stone, the drainage structure starts to function. Since the first diversion groove 401 and the second diversion groove 402 are perpendicular to each other and evenly distributed, they can cover the surface of the paving stone in all directions. The rainwater will flow downward along the first diversion groove 401 and the second diversion groove 402 with an inclined bottom. The design of the second diversion groove 402 with a higher center and lower ends makes the rainwater quickly converge to both sides. Then, through the "return" shaped drainage channel 5 that is connected to both the first diversion groove 401 and the second diversion groove 402, the surface rainwater is quickly collected. The collected rainwater flows downward along the drainage channel 5 and enters the drainage trough 6 that is also designed in a "return" shape. The drainage trough 6 and the drainage channel 5 form an L-shaped cross-section structure. During the drainage process, it can effectively block larger debris from entering the drainage holes 7, avoiding blockage of the drainage channel 5. And it can effectively prevent water from splashing upwards. The rainwater flows in the drainage trough 6 and finally is discharged through the evenly distributed drainage holes 7 on the inner wall of the drainage trough 6. The drainage holes 7 penetrate through the drainage layer 2 and the foundation layer 1, enabling the rainwater to be smoothly discharged to the ground, completing the entire drainage process, and achieving rapid and effective drainage of the accumulated water on the surface of the paving stone, avoiding the problem of surface water accumulation.
[0033] Embodiment 2: Please refer to Figures 1-8 , on the basis of Embodiment 1, a limiting structure is also disclosed, and its specific structure is as follows: Anti-slip patterns 203 are provided on the outer wall of the drainage layer 2. The cross-section of the foundation layer 1 is designed in a "convex" shape. An installation groove 201 is provided at the bottom of the drainage layer 2, and the inner wall of the installation groove 201 is fitted with the top of the foundation layer 1. Limiting protrusions 202 are provided on the inner wall of the installation groove 201 in an array distribution. A limiting groove 101 is provided on the top of the foundation layer 1, and the inner wall of the limiting groove 101 is fitted with the outer wall of the limiting protrusion 202. The drainage layer 2 and the foundation layer 1 are fixed by bonding. The buffer layer 3 is made of a multi-layer elastic net material, and fixed convex points 301 are provided on the top of the buffer layer 3 in an array distribution. A fixed groove 102 is provided at the bottom of the foundation layer 1, and the inner wall of the fixed groove 102 is fitted with the outer wall of the fixed convex point 301.
[0034] During use, the base layer 1 and drainage layer 2 are connected by a U-shaped fitting mounting groove 201, a limiting protrusion 202, and a limiting groove 101, as well as adhesive fixation, ensuring the connection stability between the various components of the paving stones. Even under external force, it can prevent the paving stones from loosening or shifting. When some parts of the structure are damaged, this connection method facilitates disassembly, repair, or replacement of damaged parts, reducing maintenance costs. The anti-slip texture 203 on the outer wall of the drainage layer 2 increases the friction of the paving stone surface, providing a good feel when pedestrians walk on it in watery or wet conditions. The good anti-slip effect reduces the risk of slipping. At the same time, the multi-layer elastic mesh buffer layer 3, through the fixed protrusions 301 and the fixed grooves 102 at the bottom of the base layer 1, can effectively buffer the impact when pedestrians step on it or vehicles run over it, reduce the damage to the paving stones, and extend the service life of the paving stones. Even if the paving stones break, the buffer layer 3 can effectively prevent the paving stones from scattering and being lost due to breakage, which would cause unevenness on the road surface. The elasticity of the buffer layer 3 can also alleviate water splashing caused by external forces to a certain extent, improving the pedestrian experience.
