The repeated effects of vehicle loads place higher demands on the integrity and continuity of the pavement. Asphalt pavement splicing technology is crucial for ensuring that the pavement in the splicing or repair area can withstand the heavy traffic pressure. The continuous improvement of the highway network often involves connecting new sections with existing ones or widening existing roads. In these situations, achieving seamless and secure asphalt pavement splices is key to ensuring the stability and service life of the entire highway structure.

[0003] A patent document with publication number CN221029372U has appeared in the prior art, which discloses an asphalt pavement overlap structure, specifically relating to the field of pavement overlap technology, including a first connecting pavement, one end of the first connecting pavement is engaged and connected to the second connecting pavement, and one end of the first connecting pavement is detachably connected to the first connecting plate. The patent document has an installation box set on the outer wall of the second connecting plate. When the asphalt pavement is overlapped, in order to improve the stability of the overlap between the pavements, after the connecting plate and the pavement are installed and spliced, the first connecting plate is inserted into the installation box through the connection of the connecting clamp rod, and the connection part of the connecting clamp rod and the telescopic clamp rod is inclined. At the same time, the spring connection drives the telescopic clamp rod and the telescopic rod to perform an extrusion movement until the connection part of the connecting clamp rod and the telescopic clamp rod is flat, and the first connecting plate and the second connecting plate are engaged and fixed, thereby achieving the effect of improving the overlap stability of the asphalt pavement.

[0004] The above-mentioned and existing technologies have the following defects: due to repeated rolling of vehicles, especially heavy-loaded vehicles, the surface of the lap plate will be permanently deformed, forming rutting.

For the lap plate, under the pressure of the vehicle, the upper asphalt may be pushed at the overlap, exacerbating the formation of rutting.

[0005] Therefore, an asphalt pavement overlap structure is proposed. Utility Model Content

[0006] The purpose of the utility model is to solve the problem that due to repeated rolling of vehicles, especially heavy-loaded vehicles, the surface of the lap plate will be permanently deformed and ruts will be formed.

[0029] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0030] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0031] like Figure 1-Figure 5 As shown, the utility model provides an asphalt pavement overlap structure, including a first pavement 1 and a second pavement 2, a first overlap plate 3 is installed on the surface of the first pavement 1, a first limiting plate 4 is installed on the surface of the first pavement 1, a second overlap plate 5 is installed on the surface of the second pavement 2, a second limiting plate 6 is installed on the surface of the second pavement 2, and an auxiliary device 7 is provided on the surface of the first limiting plate 4.

[0032] The specific setting and function of the auxiliary device 7 will be described in detail below.

[0033] like Figure 2-Figure 5As shown, the auxiliary device 7 includes two first cover shells 701, and the two first cover shells 701 are fixedly connected to the first limit plate 4. The surface of the first cover shell 701 is slidably connected to the first telescopic plate 702, and the first telescopic plate 702 is fixedly connected to the first lap plate 3. The surface of the first lap plate 3 is fixedly connected to the connecting plate 703, and the surface of the connecting plate 703 is fixedly connected to the damping rod 704. The damping rod 704 is fixedly connected to the first limit plate 4, and the surface of the damping rod 704 is sleeved with a first spring 705. The two ends of the first spring 705 are fixedly connected to the connecting plate 703 and the first limit plate 4 respectively. The surface of the first limit plate 4 is fixedly connected to a block 706, and the surface of the second limit plate 6 is fixedly connected. The second cover shell 707 is slidably connected to the surface of the second telescopic plate 708, and the second telescopic plate 708 is fixedly connected to the second lap plate 5. A card hole 709 is provided on the surface of the second limiting plate 6. The card hole 709 is adapted to the size of the card block 706. A groove 710 is provided on the surface of the card block 706. The surface of the groove 710 is rotatably connected to the adjustment plate 711. The surface of the adjustment plate 711 is fixedly connected to the second spring 712. The second spring 712 is fixedly connected to the groove 710. When the card block 706 passes through the card hole 709, the second spring 712 will drive one end of the adjustment plate 711 to rotate under the action of its own elastic force. At this time, the groove 710 and the adjustment plate 710 are used. When the locking cam 711 is in the closed position, the locking cam 713 is in the closed position, and the locking cam 713 is in the closed position, so that the locking cam 713 is in the closed position and the locking cam 713 is in the closed position. 715 abuts against the second limit plate 6. At this time, the protective pad 715 made of rubber can protect the direct contact surface between the block 714 and the second limit plate 6. The surface of the block 706 is fixedly connected with a sharp cone 716, which is a stainless steel cone. The block 706 will drive the sharp cone 716 to enter the card hole 709. At this time, the sharp cone 716 can facilitate the block 706 to enter the card hole 709. The surface of the limit plate is fixedly connected with an auxiliary ring 717, which is a conical ring. The block 706 will drive the adjustment plate 711 on the groove 710 to approach the auxiliary ring 717 on the card hole 709. At this time, the auxiliary cone, which is a conical ring, can squeeze the adjustment plate 711 during the movement.

[0034] The overall working principle is that when the first road surface 1 and the second road surface 2 are overlapped, the block 706 on the first limiting plate 4 is first inserted into the locking hole 709 on the second limiting plate 6, and then the block 706 will drive the pointed cone 716 to enter the locking hole 709. At this time, the pointed cone 716 can facilitate the entry of the block 706 into the locking hole 709. At the same time, the block 706 will drive the adjusting plate 711 on the groove 710 to approach the auxiliary ring 717 on the locking hole 709. At this time, the auxiliary cone, which is a conical ring, can squeeze the adjusting plate 711 during the movement, and then one end of the adjusting plate 711 will rotate along the surface of the groove 710. At the same time, the other end of the adjusting plate 711 will squeeze one end of the second spring 712 to move in the direction close to the groove 710. When the locking cam 711 is in the state of being stepped on and locked, the locking cam 711 is in the state of being stepped on and locked, and the locking cam 711 is in the state of being stepped on and locked, and the locking cam 711 is in the state of being stepped on and locked, and the locking cam 711 is in the state of being stepped on and locked. When the first and second lap plates 3 and 5 are in contact with each other, the protective pad 715 made of rubber can protect the direct contact surface between the stopper 714 and the second limit plate 6. After the first lap plate 3 and the second lap plate 5 are connected, since the first road surface 1 and the second road surface 2 will be subjected to the pressure of the transport vehicle for a long time, when the first lap plate 3 and the second lap plate 5 are subjected to the pressure of the transport vehicle, the first lap plate 3 and the second lap plate 5 will respectively drive the first telescopic plate 702 and the second telescopic plate 708 to slide along the surfaces of the first cover shell 701 and the second cover shell 707, and transmit the pressure to the connecting plate 703, and then the connecting plate 703 will transmit the pressure to the first spring 705. At the same time, the first spring 705 will absorb the pressure given by the transport vehicle with its own elastic force. Then, the first spring 705 will prevent repeated sideways jumping under the action of the damping rod 704. By setting up the auxiliary device 7, the cooperation between the first cover 701, the first telescopic plate 702, the connecting plate 703, the damping rod 704, the first spring 705, the clamping block 706, the second cover 707, the second telescopic plate 708 and the clamping hole 709 can be used to absorb the pressure applied by the transport vehicle to the first lap plate 3 and the second lap plate 5, thereby avoiding the permanent deformation of the lap plate surface caused by repeated rolling of the vehicle, especially heavy-loaded vehicles, and the formation of rutting. In a high temperature environment, the asphalt material becomes soft and the rutting problem will be more serious. For the lap plate, under the pressure of the vehicle, the upper asphalt may move at the lap joint, aggravating the formation of rutting.The cushioning effect of the lap joint plate is improved, and the protection of the lap joint plate is further improved.

Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes for application in other fields. However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
