Description

Technical Field

[0001] This utility model relates to the field of municipal road technology, and in particular to a permeable pavement structure for municipal roads. Background Technology

[0002] Municipal roads are an important component of urban infrastructure and the backbone of the urban transportation network. They serve the functions of transporting people and vehicles and distributing logistics within the city, and are of key significance to urban economic development and residents' daily lives. They include not only motor vehicle lanes, non-motor vehicle lanes, and sidewalks, but also ancillary projects such as road greening, drainage systems, traffic signs and markings, and lighting facilities. They integrate multiple functions such as traffic flow, municipal utilities, and landscaping. Through scientific planning and construction, they ensure the efficient operation of urban transportation and enhance the overall image and quality of the city.

[0003] A search revealed Chinese Patent Publication No. CN222455727U, which discloses a permeable pavement structure for municipal roads, specifically relating to the field of municipal road technology. The structure includes a pavement with several drainage components on both sides, a median strip in the middle, side foundations on the bottom sides, and a central foundation in the middle of the bottom. A central buffer plate is positioned between the central and side foundations, and absorbent sponges are placed on the side of the central buffer plate closest to both the central and side foundations. This invention allows rainwater to connect with the foundation through the absorbent sponges, thereby irrigating the land beneath the foundation, ensuring the normal growth of urban trees, and mitigating the "heat island effect." However, traditional concrete and asphalt pavements are completely impermeable, exacerbating urban flooding and groundwater shortages. Furthermore, while permeable bricks have some permeability, their strength and durability are insufficient to meet the demands of high-intensity traffic. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a permeable pavement structure for municipal roads, aiming to improve the problem that traditional concrete and asphalt pavements are completely impermeable, which exacerbates urban flooding and groundwater shortages. Furthermore, although permeable bricks have a certain degree of permeability, their strength and durability are insufficient, making it difficult to meet the demands of high-intensity traffic.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a permeable pavement structure for municipal roads, comprising a permeable layer one, a support layer one at the bottom of the permeable layer one, a base layer one at the bottom of the support layer one, a permeable layer two on the right side of the permeable layer one, a support layer two on the right side of the support layer one, a base layer two on the right side of the base layer one, and a connecting mechanism installed on the right side of the support layer one, the connecting mechanism being used to connect the support layer two.

[0006] The above technical solution involves permeable layer one and permeable layer two, which are made of porous permeable materials and are located on the top layer of the road structure. They can quickly absorb and infiltrate rainwater. Below them are support layer one and support layer two, which are made of high-strength permeable concrete to ensure that the permeability is not affected. The bottom layer consists of base layer one and base layer two, which are made of graded crushed stone.

[0007] As a further description of the above technical solution:

[0008] The connecting mechanism includes two connecting plates. The connecting plates are fixedly connected to the right side of the outer wall of the first support layer. An installation groove is provided on the outer side of the connecting plate. A spring is fixedly connected to the inner wall of the installation groove. A hemisphere is fixedly connected to the other end of the spring. Connecting grooves are provided at the front and rear ends of the left side of the second support layer. Placement grooves are provided at the front and rear ends of the outer side of the second support layer. A locking rod is slidably connected to the inner side of the placement groove.

[0009] The above technical solution involves first aligning the connecting plate of support layer one with support layer two, so that the mounting groove on the outside of the connecting plate corresponds to the connecting groove at the front and rear ends of the left side of support layer two. A spring with compression and rebound function is fixed on the inner wall of the mounting groove, and a hemisphere is fixed at the other end of the spring. Then, the locking rod that slides in the groove at the front and rear ends of the outside of support layer two is pushed. The locking rod pushes the hemisphere to compress the spring, thereby completing the effective connection between support layer one and support layer two.

[0010] As a further description of the above technical solution:

[0011] Both the first and second permeable layers are provided with a connecting plate on their outer sides, and the front and rear ends of the connecting plate are threaded with screws.

[0012] The above technical solution involves installing a connecting plate on both the first and second permeable layers, with the connecting plate engaging with screw one.

[0013] As a further description of the above technical solution:

[0014] Both the base layer one and the base layer two are provided with a fixing plate at their bottom, and screws are threaded to the front and rear ends of the bottom rear side of the fixing plate.

[0015] The above technical solution involves installing a fixing plate at the bottom of both the base layer 1 and the base layer 2, and installing a screw 2 on the fixing plate, with the fixing plate and screw 2 working together.

[0016] As a further description of the above technical solution:

[0017] A rubber ring is provided on the outer side of the locking rod, and a screw is threadedly connected to the outer side of the rubber ring.

[0018] The above technical solution involves installing a rubber ring on the locking rod and a screw on the rubber ring, with the rubber ring and screw engaging with each other.

[0019] This utility model has the following beneficial effects:

[0020] 1. In this utility model, the permeable layer, the support layer, and the base layer work together to effectively solve the problem of urban flooding. Rainwater infiltrates quickly through the permeable pavement, reducing surface runoff, promoting groundwater replenishment, alleviating the problem of groundwater level decline, regulating urban surface temperature and humidity, improving the growth environment of surface plants, enhancing the urban ecological regulation function, and the pavement structure has high strength and good durability, making it suitable for high-intensity traffic demands.

[0021] 2. In this utility model, when connecting support layer one and support layer two, the connecting plate is fixed on support layer one and has an installation groove and a spring. The spring provides a compression and rebound function and connects the hemisphere. Support layer two has a connecting groove and a placement groove for sliding the locking rod. After the connecting plate and support layer two are connected, the locking rod pushes the hemisphere to achieve effective connection and tight fixation of support layer one and support layer two.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0030] Reference Figure 1 , Figure 2 and Figure 4 An embodiment of this utility model provides a permeable pavement structure for municipal roads, including a permeable layer 1, a support layer 3 made of high-strength permeable concrete at the bottom of the permeable layer 1, a base layer 4 at the bottom of the support layer 3, a permeable layer 5 on the right side of the permeable layer 1, a support layer 6 on the right side of the support layer 3, a base layer 7 on the right side of the base layer 4, a connecting mechanism 2 installed on the right side of the support layer 3, the connecting mechanism 2 being used to connect the support layer 6, and a connecting plate 8 on the outer side of both the permeable layer 1 and the permeable layer 5, with screws 9 threadedly connected to the front and rear ends of the outer side of the connecting plate 8, the connecting plate 8 being fixed by the screws 9;

[0031] Specifically, permeable layer 1 and permeable layer 2 are made of porous permeable material and are located on the top layer of the pavement structure. They can quickly absorb and infiltrate rainwater. Below them are support layer 3 and support layer 2, which are made of high-strength permeable concrete. They can withstand vehicle loads while ensuring that the permeability is not affected. At the bottom layer are base layer 4 and base layer 2, which are made of graded crushed stone. They not only further filter and store infiltrated rainwater, but also guide rainwater to infiltrate into the ground. Both permeable layer 1 and permeable layer 2 are provided with connecting plates 8 on their outer sides. The front and rear ends of the outer side of the connecting plates 8 are connected with screws 9 by threads. The connecting plates 8 are fixed by screws 9.

[0032] Reference Figure 1 , Figure 3 and Figure 5The connecting mechanism 2 includes two connecting plates 201. The connecting plates 201 are fixedly connected to the right side of the outer wall of the support layer 1 3. The outer side of the connecting plate 201 is provided with an installation groove 202. The inner wall of the installation groove 202 is fixedly connected with a spring 203, which plays a role in compression and rebound. The other end of the spring 203 is fixedly connected with a hemisphere 204. The front and rear ends of the left side of the support layer 2 6 are provided with connecting grooves 205. The front and rear ends of the outer side of the support layer 2 6 are provided with placement grooves 206. The inner side of the placement groove 206 is slidably connected with a locking rod 207. The locking rod 207 can push the hemisphere 204. A rubber ring 12 is provided on the outer side of the locking rod 207. A screw 3 13 is threadedly connected to the outer side of the rubber ring 12. The rubber ring 12 is fixed by the screw 3 13, so that the locking rod 207 can be operated better.

[0033] Specifically, when connecting support layer 3 and support layer 6, a connecting plate 201 is fixed to support layer 3. The connecting plate 201 has a mounting groove 202, and a spring 203 is securely mounted on the inner wall of the mounting groove 202. The spring 203 provides compression and rebound, and its other end is connected to a hemispherical ball 204. Meanwhile, support layer 6 has a connecting groove 205, allowing the connecting plate 201 to engage with the connecting groove 205. Furthermore, support layer 6 also has a placement groove 206, which engages with the locking mechanism. With the lever 207 engaged, by pushing the locking lever 207 placed inside the placement groove 206, the locking lever 207 will slide smoothly in the placement groove 206. When the locking lever 207 contacts the hemisphere 204, it will apply a pushing force to it, causing the hemisphere 204 to compress the connected spring 203, so that the support layer 1 3 and the support layer 2 6 are effectively connected. The outer side of the locking lever 207 is provided with a rubber ring 12, and the outer side of the rubber ring 12 is connected to the screw 3 13 by threads. Through the fixing action of the screw 3 13, the rubber ring 12 is stabilized, which can better operate the locking lever 207.

[0034] Reference Figure 2 and Figure 3 Both the bottom of the base layer 1 4 and the bottom of the base layer 2 7 are provided with fixing plates 10. The bottom rear side and front and rear ends of the fixing plates 10 are threaded with screws 2 11, and the fixing plates 10 are fixed by screws 2 11.

[0035] Specifically, both the base layer 1 4 and the base layer 2 7 are provided with a fixing plate 10 at the bottom, and the fixing plate 10 is connected to the screw 2 11 by threads at the bottom, thereby making the fixing plate 10 more securely fixed.

[0036] Working principle: Permeable layer 1 and permeable layer 2 are made of porous permeable material and are located on the top layer of the road surface for rapid rainwater infiltration; support layer 3 and support layer 2 are located below the permeable layers and are made of high-strength permeable concrete to bear vehicle loads and maintain permeability; base layer 4 and base layer 2 are located at the bottom layer and are made of graded crushed stone to further filter and store infiltrated rainwater and guide rainwater to infiltrate into the ground. Permeable layer 1 and permeable layer 2 are fixed to support layer 3 and support layer 2 by adhesive, and support layer 3 and support layer 2 are connected to base layer 4 and base layer 2 by compaction.

[0037] During the connection of support layer 3 and support layer 6, the connecting plate 201 is fixed to support layer 3. A mounting groove 202 is pre-cut on the connecting plate 201, and a spring 203 is securely fixed to the inner wall of the mounting groove 202. The spring 203 provides compression and rebound. The other end of the spring 203 is connected to a hemispherical ball 204. Meanwhile, a connecting groove 205 is cut on support layer 6, allowing the connecting plate 201 to engage with it. A placement groove 206 is also provided on support layer 6 to accommodate the engaging rod 207. The space provides sliding space. When the connecting plate 201 is aligned with the second support layer 6, and the mounting groove 202 and the connecting groove 205 are accurately aligned, the locking rod 207 placed inside the placement groove 206 is pushed. The locking rod 207 slides smoothly in the placement groove 206. When it contacts the hemisphere 204, it applies a pushing force to the hemisphere 204. After being pushed by the locking rod 207, the hemisphere 204 squeezes the spring 203 connected to it, causing the spring 203 to undergo compression deformation. Through this cooperation, the effective connection between the first support layer 3 and the second support layer 6 is completed, ensuring a tight connection between the two.

[0038] Finally, it should be noted that the above description is only 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
