[0028] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0029] Please see Figure 1 The high crack-resistant roadbed protection structure in this embodiment includes a roadbed body 1, which includes a base layer 11 and a protection structure 12, with the protection structure 12 disposed on the top of the base layer 11.
[0030] Please see Figures 1 to 3The protective structure 12 in this embodiment includes a first elastic layer 121, a reinforcing layer 122 fixedly installed on the top of the first elastic layer 121, a second elastic layer 123 fixedly installed on the top of the reinforcing layer 122, a protective net 124 fixedly installed on the top of the second elastic layer 123, and an anti-freeze cracking structure fixedly installed on the top of the protective net 124.
[0031] The base layer 11 is composed of soil and mixed sand and gravel, which bears the load of roads and vehicles and serves as the foundation of the entire roadbed body 1. The first elastic layer 121 is fixed to the top of the base layer 11.
[0032] In addition, both the first elastic layer 121 and the second elastic layer 123 are polymer mortars. Polymer mortar is an elastic mortar material, whose main components include cement, aggregates, and organic polymers. It has excellent bonding properties, flexibility, and durability, and can significantly improve the bonding force of cement mortar, making it integrated with the structure and enhancing overall stability. In subgrade construction, polymer mortar can significantly improve the bonding strength and crack resistance of the subgrade body 1, enabling it to better resist temperature changes and minor structural movements. The reinforcement layer 122 is a reinforcing fiber mesh. The main functions of the reinforcing fiber mesh in the subgrade include enhancing its stability and durability, improving its load-bearing capacity and crack resistance. By adding fiber mesh to the subgrade, erosion and scouring of the subgrade can be effectively prevented, and the tensile and shear strength of the subgrade can be improved, thereby enhancing the overall load-bearing capacity of the subgrade.
[0033] Furthermore, the first elastic layer 121, the reinforcing layer 122, and the second elastic layer 123 form a crack-resistant structure. The two layers of polymer mortar can deform and restore the base layer 11. In addition, through the reinforcement of the reinforcing fiber mesh, the stress in the soil within the base layer 11 can be absorbed and dispersed, thereby effectively reducing the generation of cracks in the main body of the roadbed 1.
[0034] Furthermore, the protective net 124 is used to prevent soil erosion, while protecting the crack-resistant structure composed of the first elastic layer 121, the reinforcing layer 122, and the second elastic layer 123 from damage by the external environment.
[0035] Please see Figure 3 The anti-freeze cracking structure in this embodiment includes an anti-corrosion layer 125, an anti-freeze layer 126 fixedly installed on the top of the anti-corrosion layer 125, a waterproof layer 127 fixedly installed on the top of the anti-freeze layer 126, and a surface layer 128 fixedly installed on the top of the waterproof layer 127.
[0036] Secondly, the anti-corrosion layer 125 is a dendritic macromolecular protective coating. This coating also possesses excellent anti-corrosion properties, resisting acid and alkali corrosion and corrosion from other oily substances. This coating does not react with most acids, alkalis, or other oily substances, does not blister, peel, or become brittle, and maintains the continuity and toughness of the paint film. Furthermore, the dendritic macromolecular protective coating effectively isolates air and moisture, preventing the protective net 124 from direct contact with the external environment, thus avoiding rust and aging. In addition, it provides good adhesion and durability, ensuring it adheres firmly to the protective net 124. The anti-corrosion layer 125 is located at the top of the protective net 124 to provide anti-corrosion protection, preventing the protective net 124 from being affected by aging, corrosion, or other phenomena.
[0037] In addition, the antifreeze layer 126 is crack-resistant cement mortar. Crack-resistant cement mortar has excellent crack resistance and can effectively prevent the roadbed from cracking under load and temperature changes. It effectively prevents the main body of the roadbed 1 from cracking due to freezing and thawing in low-temperature environments, thus ensuring the stability and durability of the main body of the roadbed 1. It can also prevent cracking of the main body of the roadbed 1 in high-temperature environments. Because the crack-resistant cement mortar adds polymer emulsion and additives, the main body of the roadbed 1 has a certain toughness and deformation capacity, thus effectively preventing cracks caused by temperature changes during use. The waterproof layer 127 is a road crack-resistant tape. The crack-resistant tape is a roll-type crack-resistant and waterproof membrane. It is made of a 1.5mm or 2mm thick polymer waterproof membrane coated on a wrinkle-resistant and heavy-duty polypropylene material and rolled together by a strict process. The road crack-resistant tape can prevent cracking of the roadbed, mainly through its unique material properties and structural design. The crack-resistant tape can tightly fit the crack, prevent water penetration, and protect the main body of the roadbed 1 from water damage. Meanwhile, its high toughness and elasticity can effectively disperse stress concentration at cracks, reduce the driving force for crack propagation, and enhance the overall strength and stability of the main roadbed 1.
[0038] Meanwhile, the base layer 11, the first elastic layer 121, the reinforcing layer 122, the second elastic layer 123, the protective net 124, and the anti-freeze and crack structure are all laid and connected together, so that the base layer 11, the first elastic layer 121, the reinforcing layer 122, the second elastic layer 123, the protective net 124, the anti-freeze layer 126, the waterproof layer 127, and the surface layer 128 are laid and connected together.
[0039] In addition, the surface layer 128 is a concrete surface layer or an asphalt layer, so as to improve the aesthetics of the main roadbed 1.
[0040] The working principle of the above embodiments is as follows:
[0041] In use, the first elastic layer 121 and the second elastic layer 123 can improve the bonding strength and crack resistance of the roadbed body 1, enabling the roadbed body 1 to better resist temperature changes and minor structural movements. The reinforcement layer 122 can effectively prevent the erosion and scouring of the roadbed, improve the tensile strength and shear strength of the roadbed, and thus enhance the overall bearing capacity of the roadbed. The crack-resistant structure composed of the first elastic layer 121, the reinforcement layer 122 and the second elastic layer 123 can deform and recover the base layer 11, and can absorb and disperse the stress in the soil within the base layer 11, thereby effectively reducing the generation of cracks in the roadbed body 1. The protective net 124 can be used to prevent soil erosion and protect the crack-resistant structure composed of the first elastic layer 121, the reinforcement layer 122 and the second elastic layer 123 from damage by the external environment, thus protecting the roadbed body 1 and reducing the phenomenon of cracking caused by the external environment.
[0042] Furthermore, the anti-corrosion layer 125 effectively isolates air and moisture, preventing the protective net 124 from directly contacting the external environment, thereby avoiding rust and aging, and extending the service life of the protective net 124.
[0043] Furthermore, the antifreeze layer 126 effectively prevents cracks in the roadbed body 1 caused by freezing and thawing in low-temperature environments, thus ensuring the stability and durability of the roadbed body 1. It can also effectively prevent cracks caused by temperature changes during use in high-temperature environments. The waterproof layer 127 can prevent cracking of the roadbed body 1, prevent water from penetrating into the roadbed body 1, and protect the roadbed body 1 from water damage, thereby further improving the protection of the roadbed body 1.
