Description

Technical Field

[0001] This application belongs to the field of pavement structure, specifically reinforced pavement structure. Background Technology

[0002] With rapid economic development and continuous technological progress, road construction is also advancing rapidly. In order to better meet people's travel needs, higher requirements are being placed on the performance of roads.

[0003] A search of patent document CN204356613U discloses a road surface structure for reinforced stone slab paving, comprising a roadbed, a rubble layer, a crushed stone layer, a reinforcing steel layer, a concrete layer, and a reinforced stone slab layer. The rubble layer is laid on the roadbed; the crushed stone layer is laid on top of the rubble layer; the reinforcing steel layer is laid on top of the crushed stone layer; the concrete layer is laid on top of the reinforcing steel layer; and the reinforced stone slab layer is laid on top of the concrete layer. The number of reinforced stone slabs laid on the cross-section of the reinforced stone slab layer is N; and high-strength concrete is filled into the gaps between two connected reinforced stone slabs. The reinforced stone slabs are reinforced artificial quartz stone slabs. This utility model uses artificial quartz stone slabs to replace traditional paving methods, offering convenience and speed; significantly reducing energy and building material consumption, effectively lowering road construction costs, and reducing environmental pollution.

[0004] However, in actual use, it was found that when the road surface pressure is too high, the inner bottom layer of the pavement is prone to cracking when the upper part of the road surface is damaged due to the multi-layer paving construction method. This results in high maintenance costs and long maintenance cycles. Therefore, a reinforced road surface structure is provided. Utility Model Content

[0006] The technical solution adopted in this application is as follows: a reinforced pavement structure, including a surface layer, a load-bearing beam at the lower end of the surface layer, a support and tension mechanism inside the load-bearing beam, and a lower base layer mechanism at the lower end of the load-bearing beam; the support and tension mechanism includes a transverse tension rod, a plurality of longitudinal tension rods are fixedly connected to the rear end of the transverse tension rod, a plurality of vertical support rods are fixedly connected to the lower ends of the transverse tension rod and the longitudinal tension rod, and a plurality of intersecting reinforcing diagonal braces are fixedly connected to the relative inner sides of the vertical support rods.

[0007] By adopting the above technical solution, the two sides of the load-bearing beam can be stretched by the transverse tension rod, while the longitudinal tension rod can stretch the front and rear ends of the transverse tension rod. The vertical support rod is then connected and fixed by the intersection of the reinforcing diagonal rods.

[0008] In a preferred embodiment, the lower base structure includes a base frame, the inner wall of which is fixedly connected to a waterproof layer, and the inner bottom of which is fixedly connected to a cast-in-place support beam.

[0012] In a preferred embodiment, a waterproof layer is fixedly connected to the inner bottom end of the load-bearing beam. The waterproof layer is angular, and its bottom end is located at the inner bottom end of the load-bearing beam.

[0013] By adopting the above technical solution, the pointed shape of the anti-water accumulation layer can prevent water vapor from seeping in from the upper end and falling to the bottom of both sides inside the load-bearing beam, thus preventing water vapor from accumulating inside.

[0014] In a preferred embodiment, multiple sets of drainage pipes are fixedly connected to the right side of the load-bearing beam, and a reinforcing adhesive layer is fixedly connected to the lower end of the surface layer.

[0015] By adopting the above technical solution, the drainage pipe facilitates the discharge of water vapor inside the load-bearing beam. The reinforcing adhesive layer is composed of synthetic fibers, which facilitates the bonding of the surface layer and the filler at the bottom. At the same time, the synthetic fibers have good tensile strength and toughness, which can enhance the crack resistance and wear resistance of the asphalt mixture.

[0017] By adopting the above technical solution, the reinforcing filler is composed of high-strength fiber materials and synthetic resin, which has excellent tensile and compressive strength and enhances the stability of the road surface.

[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:

[0019] In this application, when the road surface is under pressure, the bottom of the road surface can be supported by the lower base structure, which effectively improves the load-bearing capacity of the road surface. At the same time, the two sides of the load-bearing beam can be stretched by the transverse tension bar, and the front and rear ends of the transverse tension bar can be stretched by the longitudinal tension bar. The vertical support bar is then connected and fixed by the intersection of the reinforcing diagonal bars, which increases the load-bearing capacity of the upper end of the road surface. Through the combination of the above structures, the road surface can be reinforced while improving maintenance efficiency. Attached Figure Description

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the embodiments of this application. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. Example

[0026] Reference Figure 1-4The reinforced pavement structure includes a surface layer 1, a load-bearing beam 2 at the lower end of the surface layer 1, a support and tension mechanism 3 inside the load-bearing beam 2, and a lower base layer mechanism 4 at the lower end of the load-bearing beam 2. The support and tension mechanism 3 includes a transverse tension rod 301, a plurality of longitudinal tension rods fixedly connected to the rear end of the transverse tension rod 301, a plurality of vertical support rods 302 fixedly connected to the lower end of the transverse tension rod 301 and the longitudinal tension rods, and a plurality of intersecting reinforcing diagonal braces 303 fixedly connected to the inner sides of the vertical support rods 302. The transverse tension rods 301 can stretch both sides of the load-bearing beam 2, while the longitudinal tension rods can stretch the front and rear ends of the transverse tension rods 301. The vertical support rods 302 are then connected and fixed by the intersection of the reinforcing diagonal braces 303.

[0027] Reference Figure 1-4 The lower base structure 4 includes a base frame 401, a waterproof layer 403 is fixedly connected to the inner wall of the base frame 401, and a cast-in-place support beam 402 is fixedly connected to the bottom of the base frame 401. The waterproof layer 403 can prevent water vapor at the bottom from entering the interior of the base frame 401 and causing damage to the base.

[0028] Reference Figure 1-4 The base frame 401 is filled with crushed stone filler 404. The lower end of the load-bearing beam 2 is fixedly connected to the upper end of the cast support beam 402. The crushed stone filler 404 has high compressive strength and is used to provide the foundation bearing capacity.

[0029] Reference Figure 1-4 A water-proof layer 6 is fixedly connected to the bottom of the inner part of the load-bearing beam 2. The water-proof layer 6 is angular and the bottom of the water-proof layer 6 is located at the bottom of the inner part of the load-bearing beam 2. The angular shape of the water-proof layer 6 allows water vapor to seep in from the top and fall from the tip to the bottom of both sides of the inner part of the load-bearing beam 2, preventing water vapor from accumulating inside.

[0030] Reference Figure 1-4 Multiple sets of drainage pipes 7 are fixedly connected to the right side of the load-bearing beam 2, and a reinforcing adhesive layer 5 is fixedly connected to the lower end of the surface layer 1. The drainage pipes 7 facilitate the discharge of water vapor inside the load-bearing beam 2. The reinforcing adhesive layer 5 is composed of synthetic fibers, which facilitates the adhesion of the surface layer 1 and the filler at the lower end. At the same time, the synthetic fibers have good tensile strength and toughness, which can enhance the crack resistance and wear resistance of the asphalt mixture.

[0031] Reference Figure 1-4 The interior of the load-bearing beam 2 is filled with reinforcing filler 8. The lower end of the reinforcing filler 8 is fixedly connected to a lower support rod 9. The reinforcing filler 8 is made of high-strength fiber materials such as glass fiber, carbon fiber, and synthetic fiber combined with synthetic resin. It has excellent tensile and compressive strength and enhances the stability of the road surface.

[0032] The implementation principle of the reinforced pavement structure embodiment of this application is as follows:

[0033] When the road surface is under pressure, the bottom of the road surface can be supported by the lower base layer mechanism 4, which effectively improves the load-bearing capacity of the road surface. At the same time, the transverse tension bar 301 can stretch the two sides of the load-bearing beam 2, and the longitudinal tension bar can stretch the front and rear ends of the transverse tension bar 301. The vertical support bar 302 is connected and fixed by the cross of the reinforcing diagonal bar 303, which increases the load-bearing pressure at the top of the road surface. At the same time, the pointed shape of the anti-water accumulation layer 6 allows water vapor to seep in from the top and fall to the bottom of both sides of the load-bearing beam 2, and then be discharged through the drainage pipe 7 to prevent water vapor from accumulating inside. The synthetic fiber of the reinforcing adhesive layer 5 bonds the surface layer 1 and the filler at the bottom, while increasing the tensile strength and toughness, which can enhance the crack resistance and wear resistance of the asphalt mixture. Through the combination of the above structures, the road surface can be reinforced and maintenance efficiency can be improved.
