Description

Technical Field

[0001] The utility model mainly relates to the technical field of concrete pavement structures, in particular to an anti-slip and wear-resistant pavement concrete structure. Background Art

[0002] With the rapid development of my country's economy, road traffic loads are increasing, and with this increase in traffic, higher requirements are being placed on the road's anti-skid and wear-resistant properties. Currently, highway pavement structures generally consist of a base layer and a surface layer. The base layer is typically a low-strength cast-in-place concrete layer, primarily used to ensure stable load transfer and reduce road settlement. The surface layer is typically an asphalt surface layer or a higher-strength cast-in-place cement concrete surface layer, designed to improve the road's anti-skid and load-bearing properties. However, the anti-skid performance of the surface layer alone is still limited.

[0003] The existing technology further sets an anti-skid and wear-resistant layer on the surface layer to increase the anti-skid performance of the top of the road surface. However, after long-term use, some parts of the road surface will be worn, thereby affecting the anti-skid performance. The cost of re-repairing the entire section is high. Partial re-repair requires scraping off the worn anti-skid and wear-resistant layer and the surface layer and filling them with repair materials. However, the outdoor temperature difference is large, and the concrete expands and contracts severely, which easily causes the anti-skid and wear-resistant layer on the top of the road surface to be irregular, affecting traffic use. Utility Model Content

[0004] The purpose of the utility model is to provide an anti-skid and wear-resistant pavement concrete structure to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned objectives, the present invention adopts the following technical solution: a skid-resistant and wear-resistant pavement concrete structure, comprising a base soil layer, on which a crushed stone layer, a high-strength layer and a grid layer are arranged in sequence from low to high, and a plurality of prefabricated splicing blocks are detachably arranged on the grid layer, the prefabricated splicing blocks comprising an skid-resistant and wear-resistant layer, cross beams and support blocks are staggered in the high-strength layer, longitudinal beams are arranged on both sides of the high-strength layer, a first reinforcing rib is arranged between the cross beam and the adjacent longitudinal beams, and a second reinforcing rib is arranged between any two of the longitudinal beams.

[0006] Preferably, the prefabricated splicing block also includes a prefabricated cement concrete layer, one end of the prefabricated cement concrete layer is connected and fixed to the bottom of the anti-slip and wear-resistant layer, the top of the grid layer is formed in a grid shape to form multiple splicing cavities, a snap-fitting protrusion is formed in the splicing cavity, and the other end of the prefabricated cement concrete layer is formed with a groove that fits with the snap-fitting protrusion. The prefabricated splicing block can be conveniently loaded and unloaded by connecting the prefabricated cement concrete layer with the splicing cavity.

[0007] Furthermore, adhesive cement is provided at the connection gap position of any two adjacent prefabricated splicing blocks, and the adhesive cement is located on the top wall of the splicing cavity. The height of the adhesive cement is lower than the top of the anti-slip and wear-resistant layer. The adhesive cement fills the gap between adjacent prefabricated splicing blocks and limits the prefabricated splicing blocks from leaving the splicing cavity in the height direction.

[0008] Preferably, the longitudinal beam is an L-shaped structure, and its L-shaped horizontal axis is inserted into the gravel layer, the first reinforcement rib is an X-shaped structure, the two end points of the first reinforcement rib are connected to the vertical axis of the longitudinal beam, the bottom of the longitudinal beam forms a connecting cone, and the connecting cone is inserted into the base soil layer. The base soil layer, gravel layer and high-strength layer are connected and reinforced through the longitudinal beam.

[0009] Preferably, the number of the second reinforcing ribs between any two longitudinal beams is three, and the second reinforcing ribs are strip-shaped steel bars with both ends respectively connected to the longitudinal beams on both sides, and the second reinforcing ribs are used to connect and reinforce the multiple longitudinal beams.

[0010] Preferably, the top of the high-strength layer and the top of the support column are located at the same horizontal height, and the height is set so that the grid layer is evenly arranged on the top of the support column and the high-strength layer.

[0011] Preferably, the support block is located at the top of the longitudinal beam, and there are multiple support blocks between any two longitudinal beams, and the multiple support blocks are equidistantly distributed along the length direction of the longitudinal beam, so that the support blocks and the longitudinal beams work together to increase the bearing performance of the high-strength layer.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. The utility model provides an anti-skid and wear-resistant pavement concrete structure, which uses a grid layer and prefabricated prefabricated splicing blocks to independently assemble and splice the anti-skid and wear-resistant layer in blocks, and fills the joints with adhesive cement with a height less than the top of the anti-skid and wear-resistant layer. It is convenient to replace and repair separately after wear and tear occurs, and it is not easy for the anti-skid and wear-resistant layer to become uneven due to structural deformation caused by thermal expansion and contraction.

[0014] 2. The utility model provides a skid-resistant and wear-resistant pavement concrete structure, which increases the pavement bearing capacity by staggered longitudinal beams and support blocks, and the support columns on both sides connect the base soil layer, gravel layer, high-strength layer and grid layer to improve the structural stability between the pavement layers, and is not prone to overall collapse due to local damage.

[0023] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0024] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0025] like Figures 1 to 3 As shown, a skid-resistant and wear-resistant pavement concrete structure includes a base soil layer 1, on which a crushed stone layer 2, a high-strength layer 3 and a grid layer 11 are arranged in sequence from low to high, and a plurality of prefabricated splicing blocks 4 are detachably arranged on the grid layer 11, and the prefabricated splicing blocks 4 include an skid-resistant and wear-resistant layer 42, longitudinal beams 7 and support blocks 8 are staggered in the high-strength layer 3, support columns 5 are arranged on both sides of the high-strength layer 3, a first reinforcing rib 9 is arranged between the longitudinal beam 7 and the adjacent support column 5, and a second reinforcing rib 10 is arranged between any two of the support columns 5.

[0026] The prefabricated splicing block 4 also includes a prefabricated cement concrete layer 41, one end of which is connected and fixed to the bottom of the anti-slip and wear-resistant layer 42. The top of the grid layer 11 is formed in a grid shape to form multiple splicing cavities 13, and a snap-in protrusion 14 is formed in the splicing cavity 13. The other end of the prefabricated cement concrete layer 41 forms a groove that fits with the snap-in protrusion 14. The multiple prefabricated splicing blocks 4 are uniformly preformed and formed by an external mold to maintain consistent shape and size. The connection gap between any two adjacent prefabricated splicing blocks 4 is cast with adhesive cement 12. The adhesive cement 12 is located on the top wall of the splicing cavity 13 to connect the adjacent prefabricated splicing blocks 4 and the top of the splicing cavity 13, limiting the movement of the prefabricated splicing blocks 4 in the height direction. The height of the adhesive cement 12 is lower than the top of the anti-slip and wear-resistant layer 42 to prevent the adhesive cement 12 from protruding from the anti-slip and wear-resistant layer 42 due to thermal expansion and contraction during the molding process.

[0027] The support column 5 is an L-shaped structure, and its L-shaped horizontal axis is inserted into the gravel layer 2. The first reinforcing rib 9 is an X-shaped structure. The two end points of the first reinforcing rib 9 are connected to the vertical axis of the support column 5. The bottom of the support column 5 forms a connecting cone 6, and the connecting cone 6 is inserted into the base soil layer 1. The top of the support column 5 and the top of the high-strength layer 3 are at the same horizontal height. The two cooperate to support the grid layer 11. The support column 5 connects the base soil layer 1, the gravel layer 2, the high-strength layer 3 and the grid layer 11 to improve the overall stability of the structure.

[0028] There are three second reinforcing ribs 10 between any two of the longitudinal beams 7. The second reinforcing ribs 10 are strip-shaped steel bars and their two ends are respectively connected to the longitudinal beams 7 on both sides. The support block 8 is located at the top of the longitudinal beam 7. There are multiple support blocks 8 between any two of the longitudinal beams 7, and the multiple support blocks 8 are equidistantly distributed along the length direction of the longitudinal beam 7. The longitudinal beams 7 and support blocks 8 are both high-strength steel structures to synergistically increase the bearing performance of the high-strength layer.

[0029] The implementation principle of the embodiment of the present application is as follows: When the structure is in use, the support columns 5 are respectively connected to the base soil layer 1, the crushed stone layer 2, the high-strength layer 3, and the mesh layer 11 to balance the forces on each structure and avoid local damage. Multiple longitudinal beams 7 and multiple support blocks 8 are staggered within the high-strength layer 3, and the first and second reinforcing ribs 9 and 10 cooperate to reinforce the longitudinal beams 7, further increasing the structural load-bearing capacity. The prefabricated splicing blocks 4 inserted into the multiple splicing cavities 13 are of the same specifications. When local wear occurs, the prefabricated splicing blocks 4 are dug out and replaced along the cement 12, and then the cement 12 is refilled. After the cement 12 is formed, the adjacent anti-skid and wear-resistant layers 42 maintain a consistent height and can be used normally.

[0030] It will be apparent to those skilled in the art that the present application is not limited to the details of the exemplary embodiments described above and that the present application can be implemented in other specific forms without departing from the essential characteristics of the present application. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present application is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be included therein. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
