Description

Technical Field

[0001] This utility model relates to the field of roadbed technology, specifically to a pavement structure for preventing roadbed settlement. Background Technology

[0002] The roadbed is the foundation of a railway track or pavement, a geotechnical structure formed through excavation or filling. Its primary function is to provide the necessary conditions for track or pavement laying and train or vehicle operation, and to bear the static and dynamic loads of the tracks, rolling stock, pavement, and traffic, while simultaneously transferring and dispersing these loads deeper into the ground. In longitudinal profile, the roadbed must ensure the required elevation of the line; in horizontal plane, it connects with bridges and tunnels to form a complete and continuous railway line. In civil engineering, the roadbed occupies a significant position in terms of construction volume, land area, and investment.

[0003] A search revealed Chinese Patent Publication No. CN214938886U, which discloses a highway pavement structure for preventing roadbed settlement. The structure includes a pit excavated on the ground. Several embedded columns, fixed to the soil below the pit, are pre-embedded in the bottom wall of the pit. The tops of the embedded columns are located within the pit. Each embedded column is fitted with an anti-settlement pipe. A fixing assembly is provided between the embedded columns and the anti-settlement pipes to secure them to each other. All anti-settlement pipes have coplanar upper surfaces and are fixed with the same anti-settlement plate. The pit is filled with a supporting concrete layer, which is fixed to the bottom and side walls of the pit. The upper surface of the supporting concrete layer is fixedly bonded to the lower surface of the anti-settlement plate. A reinforced concrete layer is fixedly laid on the upper surface of the anti-settlement plate, and a pavement layer is fixedly laid on the upper surface of the reinforced concrete layer. This application has the effect of improving the anti-settlement capacity of highways. Although this application can solve the problem that highways are prone to settlement due to long-term driving on the road surface, it is not only vehicles that drive on the road surface for a long time. In the event of severe weather, the internal framework of the roadbed is soaked in water for a long time, which causes it to rust and become unable to support the road surface. This is also an important reason. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a road surface structure that prevents roadbed settlement. The aim is to solve the problem that although the existing technology can solve the problem that the road surface is prone to settlement due to long-term vehicle traffic, it is not only due to vehicles driving on the road surface for a long time, but also because the internal framework of the roadbed is soaked in water for a long time in severe weather, which causes rust and makes it unable to continue to support the road surface.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A pavement structure for preventing roadbed settlement includes a foundation structure and a pavement structure, wherein the pavement structure is installed on top of the foundation structure;

[0007] The foundation structure consists of a foundation body and an anti-settlement cushion layer. A water-retaining plate is installed on the top of the foundation body, and drainage ditches are installed on both sides of the top of the foundation body. A groove is opened at the bottom of the foundation body, and an anti-settlement cushion layer is installed inside the groove. The anti-settlement cushion layer consists of an anti-settlement plate layer, a reinforcing plate layer, and a pre-embedded plate layer. A reinforcing plate layer is installed at the bottom of the anti-settlement plate layer, and a pre-embedded plate layer is installed at the bottom of the reinforcing plate layer.

[0008] Preferably, the road structure consists of a road surface and drainage grooves. Several drainage grooves are provided on both sides of the road surface. The road surface consists of an asphalt pavement layer, a reinforced concrete reinforcement layer, and a load-bearing slab layer. A reinforced concrete reinforcement layer is provided at the bottom of the asphalt pavement layer, and a load-bearing slab layer is provided at the bottom of the reinforced concrete reinforcement layer.

[0009] Preferably, the foundation body adopts a convex-shaped structure design, and the drainage ditch is installed on both sides of the low-lying area at the top of the foundation body.

[0010] Preferably, the water baffle is fitted onto the top of the protrusion of the ground body, and the top of the water baffle has a triangular structure.

[0011] Preferably, the road surface is designed as a trapezoidal structure, and the drainage holes are opened on the inclined surfaces on both sides of the road surface.

[0012] Preferably, the road surface is installed on top of the foundation body, and grooves are provided between both ends of the road surface and both ends of the foundation body.

[0013] Preferably, the drainage ditch is made of stainless steel.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This utility model, through its foundation structure, allows rainwater to flow from drainage holes on both sides of the road surface into drainage ditches during severe rainstorms. The drainage ditches then guide the rainwater into sewers or even recycle it for garden irrigation. Other rainwater seeps through the road surface, and the water-retaining plates on the foundation block the seeping rainwater and direct it to the drainage ditches at both ends of the foundation. The anti-settlement pad layer in the groove at the bottom of the foundation effectively supports the foundation and, being located at the center where the load-bearing pressure is greatest, significantly reduces the risk of foundation settlement.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Example:

[0023] Please see Figures 1-4 A pavement structure for preventing roadbed settlement includes a foundation structure 1 and a pavement structure 2. The pavement structure 2 is installed on top of the foundation structure 1. The foundation structure 1 consists of a foundation body 11 and an anti-settlement cushion layer 13. A water-retaining plate 112 is installed on top of the foundation body 11. Drainage ditches 12 are installed on both sides of the top of the foundation body 11. A groove 111 is formed at the bottom of the foundation body 11. The anti-settlement cushion layer 13 is installed inside the groove 111. The anti-settlement cushion layer 13 consists of an anti-settlement plate layer 131, a reinforcing plate layer 132, and a pre-embedded plate layer 133. The reinforcing plate layer 132 is installed at the bottom of the anti-settlement plate layer 131, and the bottom of the reinforcing plate layer 132 is installed with... With a pre-embedded slab layer 133, rainwater can flow from the drainage holes 22 on both sides of the road surface 21 into the drainage ditch 12 during severe rainstorms. The rainwater is then directed to the sewer or even recycled for garden irrigation through the drainage ditch 12. Other rainwater seeps into the road surface 21, and the water-blocking plate 112 on the foundation 11 can block the seeping rainwater and direct it to the drainage ditch 12 at both ends of the foundation 11. The anti-settlement pad layer 13 in the groove 111 at the bottom of the foundation 11 can effectively support the foundation 11 and is located at the center where the load-bearing pressure is greatest, which can greatly reduce the risk of foundation settlement.

[0024] Please see Figures 1-2 The road structure 2 consists of a road surface 21 and drainage holes 22. Several drainage holes 22 are provided on both sides of the road surface 21. The road surface 21 consists of an asphalt pavement layer 211, a reinforced concrete reinforcement layer 212, and a load-bearing slab layer 213. The bottom of the asphalt pavement layer 211 is provided with a reinforced concrete reinforcement layer 212, and the bottom of the reinforced concrete reinforcement layer 212 is provided with a load-bearing slab layer 213. Rainwater can be guided into the drainage ditch 12 through the drainage holes 22, and the reinforced concrete reinforcement layer 212 and the load-bearing slab layer 213 can effectively reduce the pressure on the asphalt pavement layer 211.

[0025] Please see Figure 1 and Figure 3 The foundation body 11 adopts a convex-shaped structure design, and the drainage ditch 12 is installed on both sides of the low-lying area on the top of the foundation body 11.

[0026] Please see Figure 3 The water baffle 112 is fitted onto the top of the protrusion of the ground body 11, and the top of the water baffle 112 is a triangular structure. Both ends of the triangular arrow at the top of the water baffle 112 are inclined, which can quickly guide rainwater into the drainage ditches 12 on both sides.

[0027] Please see Figures 1-2 The road surface 21 is designed with a trapezoidal structure. Drainage holes and grooves 22 are opened on the inclined surfaces on both sides of the road surface 21. The center of the road surface 21 bears the greatest pressure. Therefore, the trapezoidal structure can not only increase the bearing capacity, but also allow the inclined surfaces on both sides to drain rainwater quickly and easily.

[0028] Please see Figure 1 The road surface 21 is installed on the top of the foundation body 11. Grooves 111 are provided between the two ends of the road surface 21 and the two ends of the foundation body 11, which allows rainwater to easily seep into the grooves 111 from the drainage holes 22 and drain away through the drainage ditch 12 at the bottom of the grooves 111. This prevents the foundation structure 1 from being soaked in water for a long time, which would cause the internal structure to rust and become fragile.

[0029] Please see Figure 1 The drainage ditch 12 is made of stainless steel. Stainless steel has excellent corrosion resistance and will not rust due to prolonged contact with rainwater, thus improving its service life.

[0030] Working principle: The overall road surface 21 has a trapezoidal structure design, which not only increases the load-bearing capacity, but also allows rainwater to drain away quickly and easily through the sloping surfaces on both sides. The road surface structure 2 can effectively reduce the pressure on the asphalt pavement layer 211 through the reinforced concrete reinforcement layer 212 and the load-bearing plate layer 213. In the event of severe rainstorms, rainwater will flow from the drainage holes 22 on both sides of the overall road surface 21 into the drainage ditch 12. The drainage ditch 12 will guide the rainwater to the sewer or even recycle it for garden irrigation. Other rainwater will seep through the overall road surface 21. The water-blocking plate 112 on the foundation body 11 can block the seeping rainwater and direct it to the drainage ditch 12 at both ends of the foundation body 11. The anti-settlement pad layer 13 in the groove 111 at the bottom of the foundation body 11 can effectively support the foundation body 11 and is located at the center where the load-bearing pressure is greatest, which can greatly reduce the risk of foundation settlement. This device has a simple structure and can not only effectively avoid the risk of roadbed settlement, but also recycle rainwater.

[0031] All technical features in this embodiment can be freely combined according to actual needs.

[0032] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
