Description

Technical Field

[0001] This application relates to the field of concrete structure technology, and in particular to a large-area concrete crack-resistant and wear-resistant structure. Background Technology

[0002] Concrete pavement refers to pavement with cement concrete slabs as the surface layer. It is a pavement structure consisting of cement concrete slabs as the surface layer, with a base layer and a subbase layer underneath. It is also known as rigid pavement and is often used in residential areas, hospitals, squares and other places that require large-area paving.

[0003] When constructing a concrete pavement, it is usually necessary to first compact the roadbed, lay a subbase on the roadbed, pour concrete on the subbase, smooth the concrete, cover it with a thin film, and spray water for curing every once in a while, thus completing the construction of the pavement.

[0004] After the existing road structure is put into use, the passage of people and various vehicles puts a large load on the road structure, and the load is uneven. As a result, part of the load is transferred downwards and part is dispersed to the sides of the road. However, the compressive strength of the sides of the road is insufficient, which will cause the road surface to crack over time. Utility Model Content

[0005] The purpose of this application is to address the problem mentioned in the background art: the existing road structure is subjected to large and uneven loads due to the passage of various vehicles, resulting in some loads being transmitted downwards and others being dispersed to the sides of the road. However, the compressive strength of the sides of the road is insufficient, which will eventually lead to cracking of the road surface. This application provides a large-area concrete crack-resistant and wear-resistant structure.

[0006] To achieve the above objectives, this application specifically adopts the following technical solution:

[0007] A large-area concrete crack-resistant and wear-resistant structure includes a concrete pavement structure, the concrete pavement structure includes a road base, a crushed stone layer is provided on the upper end of the road base, a fine stone layer is provided on the upper end of the crushed stone layer, a crack-resistant concrete layer is provided on the upper end of the fine stone layer, and a crack-resistant structure is provided on the road base.

[0008] By adopting the above technical solution, the concrete pavement structure composed of road base, crushed stone layer, fine stone layer and crack-resistant concrete layer has strong compressive strength and crack resistance, which is conducive to long-term use. At the same time, the crack-resistant structure can further improve the crack resistance of the concrete pavement structure and further improve its service life.

[0009] Furthermore, the anti-cracking structure includes a support frame fixed to the side of the road base layer. The support frame is symmetrically arranged and has an "L" shape. A spike is fixed at the lower end of the support frame, and the spike extends into the interior of the road base layer.

[0010] By adopting the above technical solution, the support frame can support and restrict both sides of the road surface, improve the compressive strength of both sides of the road surface structure, and thus improve the overall crack resistance of the road surface.

[0011] Furthermore, a reinforcing mesh is fixed to the side of the support frame, and the reinforcing mesh is located between the crushed stone layer and the fine stone layer.

[0012] By adopting the above technical solution, the connection between the support frame and the crushed stone layer and the fine stone layer can be improved by placing the reinforcing mesh between them, thereby improving the overall integrity between the support frame and the road structure.

[0013] Furthermore, a second reinforcing mesh is fixed to the side of the support frame. The second reinforcing mesh is located inside the crack-resistant concrete layer and is wavy.

[0014] By adopting the above technical solution, the connection between the support frame and the crack-resistant concrete layer can be improved by reinforcing the second mesh, thereby improving the support effect of the support frame on the entire road structure.

[0015] Furthermore, a wire mesh layer is provided on the upper end of the road base layer, and the crushed stone layer is laid on the wire mesh layer.

[0016] By adopting the above technical solution, the load-bearing capacity and compressive strength of the road base layer can be improved through the steel wire mesh layer.

[0017] Furthermore, a steel reinforcement layer is provided inside the concrete layer, which is composed of steel bars arranged in a crisscross pattern.

[0018] By adopting the above technical solution and setting a steel reinforcement layer inside the crack-resistant concrete layer, the overall strength and crack resistance of the crack-resistant concrete layer can be improved.

[0019] Furthermore, a spacer is provided at the lower end of the reinforcing bar layer, and there are multiple spacers arranged in a matrix.

[0020] By adopting the above technical solution, the reinforcement layer can be raised by the spacer block, so that the concrete can completely cover the reinforcement layer, thereby improving the integrity of the reinforcement layer and the crack-resistant concrete layer.

[0021] Furthermore, a corundum layer is provided on the upper end of the crack-resistant concrete layer.

[0022] By adopting the above technical solution and setting a corundum layer on the crack-resistant concrete layer, the overall wear resistance of the pavement structure can be improved, and the crack resistance of the pavement can be further improved, thereby increasing the service life of the pavement structure.

[0023] In summary, this application includes at least one of the following beneficial effects;

[0024] 1. In this application, during construction, the support frame is placed above the road base layer, and the spikes at the lower end of the support frame are inserted into the road base layer. During construction, the first reinforcing mesh is located between the crushed stone layer and the fine stone layer, and the second reinforcing mesh is located inside the crack-resistant concrete layer. The crack-resistant structure can support both sides of the road structure, improve the compressive strength of both sides of the road structure, and thus improve the crack resistance of the entire road surface.

[0025] 2. In this application, after the crack-resistant concrete layer is constructed, while the crack-resistant concrete is in a semi-dry state, a mortar containing corundum is laid, ground smooth, and then polished. The corundum layer can improve the wear resistance of the pavement structure, further improve the crack resistance of the pavement structure, and thus improve the service life of the pavement structure.

[0032] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0033] This application discloses a large-area concrete crack-resistant and wear-resistant structure.

[0034] Reference Figure 1 and Figure 2 A large-area concrete crack-resistant and wear-resistant structure includes a concrete pavement structure 1, which includes a road base 101, a crushed stone layer 102 at the upper end of the road base support, a fine stone layer 103 at the upper end of the crushed stone layer 102, a crack-resistant concrete layer 104 at the upper end of the fine stone layer 103, and a crack-resistant structure on the road base 101.

[0035] The subgrade 101 serves as the base layer, supporting various pavement structural layers. The crushed stone layer 102 disperses the pressure on the pavement structure, reducing subgrade deformation. The fine stone layer 103 bears the vertical force of the load on the pavement structure and distributes stress to the lower layers. The crack-resistant concrete layer 104 directly bears various load stresses, ensuring normal pavement use. When the pavement structure is put into use, the crack-resistant structure supports both sides of the pavement structure, improving the compressive strength of both sides and thus enhancing the overall crack resistance of the pavement.

[0036] Reference Figures 2-4 The anti-cracking structure includes a support frame 201 fixed to the side of the road base 101. The support frames 201 are symmetrically arranged and are in an "L" shape. A spike 202 is fixed at the lower end of the support frame 201 and extends into the interior of the road base 101.

[0037] Among them, a reinforcing mesh 203 is fixed on the side of the support frame 201, and the reinforcing mesh 203 is located between the crushed stone layer 102 and the fine stone layer 103.

[0038] Furthermore, a reinforcing mesh 204 is fixed to the side of the support frame 201. The reinforcing mesh 204 is located inside the crack-resistant concrete layer 104 and is wavy.

[0039] After the road base layer 101 is constructed, the support frame 201 is placed on top of the road base layer 101, and the spikes 202 at the lower end of the support frame 201 are inserted into the road base layer 101, thus completing the installation of the support frame 201. Then, a crushed stone layer 102 is laid, located below the first reinforcing mesh 203. After the crushed stone layer 102 is laid, a fine stone layer 103 is laid, located above the first reinforcing mesh 203. During subsequent construction, a second reinforcing mesh 204 is placed inside the crack-resistant concrete layer 104. The first and second reinforcing meshes 203 and 204 enhance the stability between the support frame 201 and the entire road structure. The crack-resistant structure supports both sides of the road structure, improving the compressive strength of both sides and thus enhancing the overall crack resistance of the road surface.

[0040] Reference Figures 2-4A wire mesh layer 3 is provided on the upper end of the road base layer 101, and a crushed stone layer 102 is laid on the wire mesh layer 3.

[0041] Using wire mesh can improve the compressive strength of the road base layer 101.

[0042] A steel reinforcement layer 4 is set inside the concrete layer, which is composed of steel bars arranged in a crisscross pattern.

[0043] Among them, a spacer 5 is provided at the lower end of the steel reinforcement layer 4, and there are multiple spacers 5 arranged in a matrix.

[0044] Before pouring the crack-resistant concrete, a steel reinforcement layer 4 is laid on the fine aggregate layer 103. The steel reinforcement layer 4 can improve the overall strength of the crack-resistant concrete layer 104, thereby improving the crack resistance of the pavement. After laying the steel reinforcement layer 4, spacers 5 need to be added under the steel reinforcement layer 4 to support it, so that the steel reinforcement layer 4 does not stick to the fine aggregate layer 103. This allows the steel reinforcement layer 4 to be completely wrapped when the crack-resistant concrete is poured later, improving the connection between the steel reinforcement layer 4 and the crack-resistant concrete layer 104.

[0045] Reference Figure 2 and Figure 4 A corundum layer 6 is provided on the upper end of the crack-resistant concrete layer 104.

[0046] After the crack-resistant concrete layer 104 is constructed, while the crack-resistant concrete is in a semi-dry state, mortar containing corundum is laid, ground smooth, and then polished. The corundum layer 6 can improve the wear resistance of the pavement structure, further improve the crack resistance of the pavement structure, and thus improve the service life of the pavement structure.

[0047] Working principle: During construction, the soil on the ground is compacted to form the road base 101. After compaction, the support frame 201 is placed on top of the road base 101, and the spikes 202 at the lower end of the support frame 201 are inserted into the road base 101, thus completing the installation of the support frame 201. Then, crushed stone is laid on the road base 101 to form a crushed stone layer 102. After the crushed stone layer 102 is laid, a fine stone layer 103 is laid, which is located above the reinforcing mesh 203. Then, a... A steel reinforcement layer 4 is installed to improve the overall strength of the crack-resistant concrete layer 104. After laying the steel reinforcement layer 4, a spacer 5 needs to be added below the steel reinforcement layer 4 to support the steel reinforcement layer 4 so that it does not stick to the fine stone layer 103. Then, crack-resistant concrete is poured to form the crack-resistant concrete layer 104. After pouring, it is smoothed. When the crack-resistant concrete is semi-dry, mortar containing corundum is laid and ground smoothed. Then, it is polished to complete the construction of the road structure. In this pavement structure, the base course 101 serves as the foundation layer, supporting various pavement structural layers. Wire mesh enhances the compressive strength of the base course 101. The crushed stone layer 102 disperses the pressure on the pavement structure, reducing subgrade deformation. The fine aggregate layer 103 bears the vertical force of the loads on the pavement structure and distributes stress to the lower layers. The crack-resistant concrete layer 104 directly bears various load stresses, ensuring normal pavement use. The reinforcing steel layer 4 enhances the overall strength of the crack-resistant concrete layer 104, preventing it from adhering to the fine aggregate layer 103, allowing it to be completely encased during subsequent crack-resistant concrete pouring. The entire anti-cracking structure supports both sides of the pavement structure, improving compressive strength and thus enhancing overall crack resistance. The corundum layer 6 improves the wear resistance of the pavement structure, further enhancing its crack resistance and extending its service life.
