Description

Technical Field

[0001] This utility model relates to the field of roadbed technology, specifically a roadbed structure for the synergistic utilization of multiple solid wastes. Background Technology

[0002] The roadbed is the foundation of the track or road surface. It is an earthwork structure formed by excavation or filling. The main function of the roadbed is to provide the necessary conditions for the laying of the track or road surface and the operation of trains or vehicles, and to bear the static and dynamic loads of the track and locomotives or the road surface and traffic loads, while transferring and spreading the loads to the depths of the foundation.

[0003] According to the search results, Chinese patent document, publication number CN220685646U, discloses a roadbed widening and splicing structure, including a ground surface, an old roadbed, and a new roadbed. The ground surface is topped with an old roadbed with protrusions on both sides, and the top left and right sides of the ground surface are topped with new roadbeds, with the old and new roadbeds in contact. One end of the new roadbed is in contact with a baffle plate, which is also in contact with the ground. The bottom inner side of the baffle plate is slidably connected to a reinforcing bar with external threads. Through the reinforcing bar, baffle plate, and new roadbed, when widening the roadbed, the old roadbed is spliced ​​to the new roadbed via the protrusions on both sides. Then, under the connection of the reinforcing bar, the baffle plate provides limiting support for the new roadbeds on both sides of the old roadbed, increasing the connection strength between the new and old roadbeds. This reduces settlement differences and ensures sufficient stability for the spliced ​​new and old roadbeds as a whole, thereby avoiding or reducing the occurrence of cracks.

[0004] However, the above technologies still have certain shortcomings. For example, when widening the roadbed, the connection strength between the new and old roadbeds is increased by using steel bars. Although this solution can improve the strength of the roadbed, it consumes a lot of resources and is costly. It may require a large amount of steel bars per kilometer of roadbed widening, and the increased self-weight of the widened structure exacerbates the risk of foundation settlement. Therefore, we provide a roadbed structure that utilizes multiple solid wastes to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a roadbed structure for the collaborative utilization of multiple solid wastes.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a roadbed structure for the collaborative utilization of multiple solid wastes, comprising a compressive bearing layer, an interface functional layer one disposed on top of the compressive bearing layer, a drainage transition layer disposed on top of the interface functional layer one, an interface functional layer two disposed on top of the drainage transition layer, and an anti-deformation layer disposed on top of the interface functional layer two, the interface functional layer one being located on the opposite side of the compressive bearing layer and the drainage transition layer, the interface functional layer two being located on the opposite side of the drainage transition layer and the anti-deformation layer, the drainage transition layer being located on the opposite side of the interface functional layer one and the interface functional layer two, and two sloping bottom layers being disposed on each side of the compressive bearing layer and the interface functional layer one, with a protective mechanism disposed at the top of the two sloping bottom layers.

[0007] The aforementioned compressive bearing layer is made of coal gangue aggregate and steel slag, wherein the particle size of the coal gangue aggregate is 5-40 mm and the particle size of the steel slag is 10-25 mm.

[0008] The aforementioned drainage transition layer is composed of bimodal pores of red mud aggregate and waste tire particles, with a porosity of 18% to 22%, a porosity of 55% to 70% for the red mud aggregate, and a particle size of 2 to 5 mm for the waste tire particles, with a porosity of 12% to 18% for the waste tire particles.

[0009] The aforementioned anti-deformation layer is made of electrolytic manganese slag and industrial gypsum, and both the first and second interface functional layers are made of polymers of nano-silica.

[0010] The aforementioned protective mechanism includes a protective base plate, a support plate, a slope protection plate, and support rods. The top end of the protective base plate is fixed to the bottom end of the support plate, the top end of the support plate is fixed to the bottom end of the slope protection plate, and one side of the slope protection plate is hinged to one end of each of the two support rods.

[0011] As described above, one end of each of the two support rods is hinged to two fixing plates, and multiple anchor bolts are fixed inside the fixing plates, with one end of each anchor bolt penetrating the fixing plate and anchored inside the protective base plate.

[0012] As described above, the top of the support plate is fixed with a plurality of anchor nails, and one end of the anchor nail penetrates the support plate and is anchored inside the protective base plate.

[0013] Compared with existing technologies, this multi-solid waste co-utilization roadbed structure has the following beneficial effects:

[0014] I. This utility model utilizes a roadbed composed of a mixture of various solid wastes. The drainage transition layer is formed by red mud aggregate and waste tire particles to create a bimodal porous structure. The deformation-resistant layer is formed by the reaction of electrolytic manganese slag and industrial gypsum to generate a cementitious substance. Both interface functional layers one and two are made of polymers of nano-silica. The synergistic utilization of various solid wastes improves the bearing capacity and drainage performance of the roadbed, reduces deformation and settlement, and enhances interlayer adhesion. Thus, by combining various solid waste materials and efficiently utilizing industrial solid waste, environmental pollution is reduced and raw material costs are lowered.

[0015] Second, this utility model uses a hinged connection between the slope protection plate, support rod, and fixing plate, which allows for flexible adjustment of the support rod angle according to the roadbed deformation, effectively avoiding the problem of breakage caused by uneven settlement of rigid connections. Then, anchor nail one penetrates the fixing plate and is anchored in the protective base plate, which can resist lateral shear force. At the same time, anchor nail two penetrates the support plate and is anchored in the protective base plate, which can prevent the slope protection plate from overturning, thereby reinforcing the slope bottom of the roadbed. In addition, the surface of the slope protection plate can also intercept landslides on the slope, avoiding safety hazards to pedestrians and vehicles on the road below.

[0024] First, the compressive bearing layer 1 is composed of a mixture of coal gangue aggregate and steel slag. The high hardness of the steel slag compensates for the insufficient strength of the coal gangue, thus improving the bearing capacity of the roadbed. The drainage transition layer 2 is composed of red mud aggregate and waste tire particles forming a bimodal porous structure with a total porosity of 18%–22%. This not only improves the drainage performance of the roadbed but also utilizes the environmentally friendly properties of red mud and waste tire particles. The deformation-resistant layer 3 is a cementitious material generated by the reaction of electrolytic manganese slag and industrial gypsum, possessing good deformation control capabilities and reducing roadbed deformation and settlement. Interface functional layers 4 and 5 are both made of polymers of nano-silica, enhancing the interlayer structure. It has good adhesion and stability, which can enhance the integrity and durability of the roadbed. By combining various solid waste materials and making efficient use of industrial solid waste, environmental pollution is reduced and raw material costs are lowered. Finally, by using a hinged connection between the parts of the protection mechanism 7, the angle of the protection mechanism 7 can be flexibly adjusted according to the deformation of the roadbed, effectively avoiding the problem of breakage caused by uneven settlement of rigid connections. It can also resist lateral shear force and prevent the protection mechanism 7 from overturning, thereby reinforcing the slope bottom of the roadbed. In addition, the surface of the protection mechanism 7 can also intercept landslides on the slope, preventing them from causing safety hazards to pedestrians and vehicles on the road below.

[0025] like Figure 1-2As shown, the compressive bearing layer 1 is made of coal gangue aggregate and steel slag. The particle size of the coal gangue aggregate is 5-40 mm, and the particle size of the steel slag is 10-25 mm. The drainage transition layer 2 is composed of red mud aggregate and waste tire particles with bimodal pores.

The deformation-resistant layer 3 is made of electrolytic manganese slag and industrial gypsum. The interface functional layer 1 4 and the interface functional layer 2 5 are both made of polymer of nano-silica.

[0026] The compressive bearing layer 1 is composed of a mixture of coal gangue aggregate and steel slag. The high hardness of the steel slag compensates for the insufficient strength of the coal gangue, thereby improving the bearing capacity of the roadbed. The drainage transition layer 2 is composed of red mud aggregate and waste tire particles forming a bimodal pore structure with a total porosity of 18% to 22%. This not only improves the drainage performance of the roadbed but also utilizes the environmentally friendly characteristics of red mud and waste tire particles. The deformation-resistant layer 3 is a cementitious substance generated by the reaction of electrolytic manganese slag and industrial gypsum. It has good deformation control capabilities and can reduce the deformation and settlement of the roadbed. The interface functional layer 1 4 and interface functional layer 2 5 are both made of polymers of nano-silica, which enhance the interlayer bonding force and have good adhesion and stability. This can enhance the integrity and durability of the roadbed. Thus, by combining various solid waste materials and efficiently utilizing industrial solid waste, environmental pollution is reduced and raw material costs are lowered.

The top end of the protective base plate 701 is fixed to the bottom end of the support plate 702, and the top end of the support plate 702 is fixed to the bottom end of the slope protection plate 703. One side of the slope protection plate 703 is hinged to one end of each of the two support rods 704. One end of each of the two support rods 704 is hinged to two fixing plates 8. Multiple anchor nails 9 are fixed inside the fixing plates 8, and one end of each anchor nail 9 passes through the fixing plate 8 and is anchored inside the protective base plate 701.

Then, the anchor nail 1 9 penetrates the fixing plate 8 and is anchored in the protective base plate 701, which can resist the lateral shear force. At the same time, the anchor nail 2 10 penetrates the support plate 702 and is anchored in the protective base plate 701, which can prevent the slope protection plate 703 from overturning, thereby reinforcing the bottom of the roadbed. In addition, the surface of the slope protection plate 703 can also intercept the landslide debris on the slope, avoiding the safety hazards to pedestrians and vehicles on the road below.

[0029] Working principle: First, the compressive bearing layer 1 is composed of a mixture of coal gangue aggregate and steel slag. The high hardness of the steel slag compensates for the insufficient strength of the coal gangue. The drainage transition layer 2 is composed of red mud aggregate and waste tire particles forming a bimodal porous structure with a total porosity of 18%–22%. This not only improves the drainage performance of the roadbed but also utilizes the environmentally friendly properties of red mud and waste tire particles.

Then, the anchor nail 1 9 penetrates the fixing plate 8 and is anchored in the protective base plate 701, which can resist the lateral shear force. At the same time, the anchor nail 2 10 penetrates the support plate 702 and is anchored in the protective base plate 701, which can prevent the slope protection plate 703 from overturning, thereby reinforcing the slope bottom of the roadbed. In addition, the surface of the slope protection plate 703 can also intercept the landslide debris.
