Description

Technical Field

[0001] This invention relates to the field of road construction technology, specifically to a connector at the junction of sponge pavement and asphalt pavement. Background Technology

[0002] Asphalt roads refer to various types of pavement constructed by incorporating road-grade asphalt materials into mineral materials. Asphalt binders enhance the ability of paving aggregates to resist damage from traffic and natural factors, resulting in smooth, dust-free, impermeable, and durable surfaces. Sponge roads, on the other hand, are a new type of pavement with water-absorbing capabilities. Like a sponge, they quickly absorb surface water and release it when needed, thus making full use of water resources and improving the urban environment. Simultaneously, sponge pavements have excellent drainage performance, significantly reducing pressure on drainage networks and minimizing urban flooding. Furthermore, this pavement structure can withstand the weight of vehicles, making it suitable for applications such as driveways, thus playing a broader environmental protection role.

[0003] Combining asphalt and sponge pavement in roadways can achieve greater durability and environmental friendliness. However, due to the differences between the two materials, the joints cannot be well bonded during installation, which can lead to cracks in the road surface and affect normal traffic. Furthermore, the different thermal expansion and contraction properties of the two materials can also cause cracks under varying climates, further impacting normal traffic. Summary of the Invention

Multiple sliding rods 17 are fixedly connected to the top surface of the second slider 24. The top surface of the sliding rods 17 passes through the first housing 1 or the second housing 2 and is inserted into the horn plate 12.

[0057] Furthermore, the two clips 19 are respectively provided with the same water inlet 18 on the first housing 1 and the second housing 2. One end of the water inlet 18 is connected to the space formed by the first housing 1 and the second housing 2, and the other end of the water inlet 18 is connected to the cross drain hole 21.

[0058] Furthermore, a fixed rod 7 is slidably connected to both the first housing 1 and the second housing 2. Each fixed rod 7 has a locking block at one end and a third cavity 33 inside each end. A common connecting rod 32 connects the two fixed rods 7, with both ends extending into the two third cavities 33. A block 34 is fixedly connected to one end of the connecting rod 32 within each third cavity 33, and the block 34 slides and fits snugly against the third cavity 33. Multiple fixing grippers 4 are fixedly connected to the opposite ends of each fixed rod 7. A grappling nail 5 is fixedly connected to each of the two closest fixed grappling plates 4, and a semi-circular cover 30 is fixedly connected to each of the two semi-circular covers 30. The two semi-circular covers 30 are arranged opposite each other and have sliding holes 9. The first housing 1 and the second housing 2 are arranged in the sliding holes 9. The first housing 1 and the second housing 2 are fixedly connected to the inner sidewalls of the two semi-circular covers 30, and the two first springs 8 are respectively sleeved on the two fixed rods 7. Elastic plates 6 are attached to the outer arc surfaces of the semi-circular covers 30 above and below the two sliding holes 9. The elastic plates 6 are fixedly connected to the first housing 1 or the second housing 2.

[0059] Furthermore, the fixed gripper 4 is V-shaped in the middle and pointed at the bottom, and the cross-sections of the fixed rod 7, the second slider 24 and the connecting rod 32 are all square.

[0060] Furthermore, a positioning connecting block is fixedly connected to one end of each of the two semicircular covers 30, and a positioning groove 28 is provided at the other end of each of the two semicircular covers 30, with the positioning connecting block matching the positioning groove 28.

[0061] When using this device, the connector is buried underground by layering. At this time, one side of the first shell 1 is an asphalt road surface, and one side of the second shell 2 is a sponge road surface. During connection, the bottom of the fixing gripper 4 is set with a pointed end and inserted into the foundation of the asphalt road surface and the sponge road surface for initial fixation to ensure the stability of the device. Then, the asphalt road surface and the sponge road surface on both sides are piled up layer by layer to fix the connector underground. Moreover, the fixing gripper 4 is set in a V shape, which can effectively increase the fixing connection surface between the fixing gripper 4 on both sides and the asphalt road surface and the sponge road surface respectively, thereby increasing its gripping force, so that the asphalt road surface and the sponge road surface are effectively gripped together by the connector, as shown in the figure. Adjacent connectors can be connected together by splicing. When splicing, the positioning connecting block on the latter connector is inserted into the positioning groove 28 for connection. In this way, the two different road surfaces are spliced ​​in rows to effectively grip together. After the two road surfaces are piled up and dried, they can be passed normally.

[0062] During seasonal traffic, due to varying climates, the two road surface materials exhibit different rates of thermal expansion and contraction. When temperatures are high, the two materials expand, causing the materials on both sides to move closer together. At this point, the first cylinder 10 slides against the second cylinder 11, compressing the second spring 31. Simultaneously, the semi-circular covers 30 on both sides move closer together, compressing the first spring 8. Because the road surface heats differently, the expansion forces differ. The sliding holes 9 provide expansion space between the two semi-circular covers 30 and the first and second housings 1 and 2 respectively, preventing damage from compression. Furthermore, the elastic plate 6 has elastic restoring force, ensuring that it remains in contact with the outer arc surface of the semi-circular cover 30. This effectively... The sliding hole 9 serves to seal the surface. When the temperature is too low, the two road surface materials shrink due to the cold, causing the materials on both sides to move away from each other. During the process of moving closer or further away, the connecting rod 32, the third cavity 33, and the block 34 can effectively guide the connection and prevent the first shell 1 and the second shell 2 from separating. At the same time, the two horn plates 12 at the top move closer or further away synchronously. Moreover, with the setting of the first compression spring 15 and the first slider 16, the slide plate 14 is always in contact with the other horn plate 12, which effectively seals the gap of its through groove 29 and prevents stones from falling between the first shell 1 and the second shell 2. This device can effectively prevent cracks from appearing on the road surface.

[0063] On rainy days, sponge pavement has a water-permeable function, while asphalt pavement cannot permeate water and is prone to water accumulation, affecting normal traffic. At this time, rainwater on the asphalt pavement flows through the third through hole 25, water inlet 18 and cross drainage hole 21 to the middle space of the first shell 1 and the second shell 2, and then flows through the water outlet 3 to the sponge pavement for water permeation. At this time, under the setting of the second compression spring 23 and the second slider 24, the arc-shaped top of the slide rod 17 is inserted into the inner top surface of the horn plate 12, which effectively plays a positioning role. During long-term traffic on the asphalt pavement, the asphalt pavement may sink, which will cause the horn plate 12 to deflect slightly under the setting of the round rod 20. At this time, the top surface of the horn plate 12 is arc-shaped, and the initial state is not affected when the horn plate 12 deflects. The rainwater accumulated in the depression of the asphalt pavement seeps in from the gap and flows through the second through hole 13 into the cavity enclosed by the first shell 1 and the second shell 2 to continue to permeate.

[0064] It should be noted that in this embodiment, the left side is an asphalt road surface and the right side is a sponge road surface.

[0065] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
