Description

Technical Field

[0001] This application relates to the field of road construction technology, and in particular to a deformation-resistant sidewalk pavement structure. Background Technology

[0002] A sidewalk is a section of road specifically for pedestrians, usually located on either side or in the middle of the road, separated from motor vehicle lanes and non-motor vehicle lanes. Its main functions are to ensure pedestrian safety, provide a comfortable walking environment, and, to some extent, beautify the city.

[0003] To maintain the permeability of the road surface, existing sidewalks generally do not use concrete for the bonding layer of permeable bricks, so as to avoid the concrete layer blocking rainwater infiltration. During construction, the base layer and sand cushion layer are laid from bottom to top in the road foundation pit, and then multiple permeable bricks are laid flat on the surface of the sand cushion layer.

[0004] The existing technical solutions mentioned above have the following defects: under long-term external forces and rainwater flow, the sand and gravel in the sand cushion layer of the sidewalk are prone to loosening or loss, resulting in hollowing or sinking of the permeable bricks and deformation of the sidewalk surface. Utility Model Content

[0005] This application provides a deformation-resistant sidewalk pavement structure to reduce sidewalk pavement deformation.

[0006] The above-mentioned technical objective of this application is achieved through the following technical solution:

[0007] A deformation-resistant pedestrian pavement structure includes a support plate laid on a base layer. The support plate has integrally formed support blocks with spherical protrusions. The support blocks are provided with leveling blocks, and at least two leveling blocks are spaced apart. One side of the leveling block is attached to the support block, and the other side of the leveling block is covered with a steel mesh. The steel mesh has multiple permeable holes spaced apart. A layer of sand and gravel is laid between the support plate and the steel mesh, and permeable bricks are laid on the steel mesh.

[0008] By adopting the above technical solutions, the load of the sidewalk is evenly distributed to the base layer, which can reduce the deformation of the sidewalk caused by external impact, increase the overall structural stability of the sidewalk, and form a hidden ditch between multiple adjacent support blocks, allowing rainwater to flow in the gravel between the support blocks, increasing the permeability of the sidewalk. At the same time, the raised support blocks can reduce the loss of gravel in the gravel layer, ensure the stability of the gravel layer, and reduce the deformation of the sidewalk.

[0009] Optionally, a buffer layer is laid between the steel mesh and the permeable brick.

[0010] By adopting the above technical solutions, the buffer layer can reduce the impact of permeable bricks on the steel mesh and gravel layer, reduce the deformation of the steel mesh and the loosening of the gravel layer caused by long-term external force, ensure that the steel mesh and gravel layer can stably support the permeable bricks, and reduce the deformation of the sidewalk pavement.

[0011] Optionally, the opening of the permeable hole is triangular.

[0012] By adopting the above technical solution, the triangular permeable holes can increase the structural strength of the sidewalk in the horizontal direction and reduce the deformation of the sidewalk surface caused by external force impacting the sidewalk edge.

[0013] Optionally, the area of ​​the permeable hole facing one end of the permeable brick is larger than the area of ​​the permeable hole facing the other end.

[0014] By adopting the above technical solution, when rainwater flows through the buffer layer, the openings of the permeable holes of the steel mesh at the end furthest from the buffer layer are smaller, which can prevent rubber particles from flowing with the water to the buffer layer, reduce the loss of rubber particles from the buffer layer, ensure the stability of the buffer layer, and reduce the deformation of the sidewalk pavement.

[0015] Optionally, the support block is provided with a flow guide groove.

[0016] By adopting the above technical solution, the diversion channel can increase the space for rainwater to flow between the support plate and the steel mesh, increase the water permeability of the sidewalk, and at the same time provide expansion space to reduce the sidewalk pavement warping or cracking caused by temperature changes.

[0017] Optionally, the four corners of the support plate are cut to form an octagon.

[0018] By adopting the above technical solution, the support plate has an octagonal surface, which makes it easy for workers to adjust the position and direction of the support plate during the laying process. After the laying is completed, drainage outlets can be formed between multiple adjacent support plates, which increases the water permeability of the support plate and provides expansion space for the support plate, reducing the lifting or cracking of the sidewalk pavement caused by temperature changes.

[0019] Optionally, a positioning post is fixedly connected to the leveling block, and one end of the positioning post is inserted into the water-permeable hole.

[0020] By adopting the above technical solution, the positioning post is inserted into the water-permeable hole of the steel mesh, which can increase the stability of the leveling block on the support block, ensure that the leveling block can maintain a stable height, and reduce the deformation of the sidewalk pavement.

[0021] Optionally, the steel mesh is made of stainless steel.

[0022] By adopting the above technical solutions, stainless steel mesh can maintain the stability of sidewalk performance, extend the service life of sidewalks, and reduce maintenance costs.

[0023] In summary, this application has the following technical effects:

[0024] 1. By setting up support blocks and steel mesh, the load of the sidewalk is evenly distributed to the base layer, which can reduce the deformation of the sidewalk caused by external impact and increase the overall structural stability of the sidewalk. Multiple adjacent support blocks can form a hidden ditch, allowing rainwater to flow in the gravel between the support blocks, increasing the permeability of the sidewalk. At the same time, the raised support blocks can reduce the loss of gravel in the gravel layer, ensure the stability of the gravel layer, and reduce the deformation of the sidewalk.

[0025] 2. By setting up a buffer layer, the impact of permeable bricks on the steel mesh and gravel layer can be reduced, the deformation of the steel mesh and the loosening of the gravel layer caused by long-term external force can be reduced, the steel mesh and gravel layer can provide stable support for the permeable bricks, and the deformation of the sidewalk pavement can be reduced.

[0026] 3. By setting positioning posts that are inserted into the permeable holes of the steel mesh, the stability of the leveling block on the support block can be increased, ensuring that the leveling block can maintain a stable height and reducing the deformation of the sidewalk pavement.

[0031] The present application will be further described in detail below with reference to the accompanying drawings.

[0032] This application discloses a deformation-resistant sidewalk pavement structure, referring to... Figure 1 and Figure 2The pedestrian pavement structure includes a support plate 1 laid on a base layer. The support plate 1 is made of a square plate. The four corners of the support plate 1 are cut to form an octagon, and the length of the four sides formed by the cut is less than the length of the other four sides. A support block 2 with a spherical protrusion is integrally formed on the support plate 1. A guide groove 21 is formed along the diameter of the support block 2. There are four guide grooves 21 that are perpendicular to each other. One end of the four guide grooves 21 is connected, and the other end is close to the four shorter sides of the support plate 1. A leveling block 3 is set on the support block 2. Four leveling blocks 3 are set at intervals and are located between two adjacent guide grooves 21. The side of the leveling block 3 facing the support block 2 is processed to form an arc surface that fits with the support block 2, and the other side of the leveling block 3 is processed to form a horizontal plane.

[0033] Reference Figure 1 and Figure 2 A layer of sand and gravel 4 is laid on the support plate 1. The sand and gravel layer 4 is laid until it is flush with the side of the leveling block 3 away from the support plate 1. A steel mesh 5 is set on the side of the leveling block 3 away from the support plate 1. The steel mesh 5 is made of stainless steel. Water-permeable holes 51 are opened on the steel mesh 5. Multiple water-permeable holes 51 are spaced apart. The opening of the water-permeable hole 51 is triangular. The opening area of ​​the water-permeable hole 51 near the support plate 1 is smaller than the opening area of ​​the water-permeable hole 51 away from the support plate 1.

[0034] Reference Figure 2 The leveling block 3 is welded with positioning posts 31 on the side facing the steel plate. There are three positioning posts 31 spaced apart. The ends of the three positioning posts 31 away from the leveling block 3 are respectively inserted into the three permeable holes 51 of the steel mesh 5. Permeable bricks 6 are laid on the steel mesh 5. The connection between two adjacent permeable bricks 6 is located above the horizontal plane of the leveling block 3. A buffer layer 7 is laid between the permeable bricks 6 and the steel mesh 5. In this embodiment, the buffer layer 7 is a buffer layer made of rubber particles.

[0035] Reference Figure 3 On the protruding spherical surface of the support block 2, there is an integrally formed strip-shaped limiting block. The length direction of the limiting block coincides with the diameter of the support block 2. Four limiting blocks are arranged at intervals and correspond one-to-one with four leveling blocks 3. The arc-shaped concave surface of the leveling block 3 is provided with a limiting groove for the limiting block to slide. The limiting groove and the limiting block are adapted to each other, so that the leveling block 3 can only slide along the length direction of the limiting block.

[0036] When this pedestrian pavement structure is used, the buffer layer 7 can reduce the impact of the permeable bricks 6 on the steel mesh 5 and the gravel layer 4, reduce the deformation of the steel mesh 5 and the loosening of the gravel layer 4 caused by long-term external forces, ensure that the steel mesh 5 and the gravel layer 4 can stably support the permeable bricks 6, reduce the deformation of the pedestrian pavement, and the stainless steel steel mesh 5 can maintain the stability of the pedestrian pavement performance, extend the service life of the pedestrian pavement, reduce maintenance costs, and distribute the load of the pedestrian pavement evenly to the base layer through the steel mesh 5, which can reduce the deformation of the pedestrian pavement caused by external impacts.

[0037] The triangular permeable holes 51 of the steel mesh 5 can increase the structural strength of the sidewalk in the horizontal direction and reduce the deformation of the sidewalk surface caused by external force impacting the sidewalk edge. The positioning post 31 is inserted into the permeable holes 51 of the steel mesh 5, which can increase the stability of the leveling block 3 on the support block 2, ensure that the leveling block 3 can maintain a stable height, and reduce the deformation of the sidewalk surface.

[0038] When rainwater flows through the buffer layer 7, the smaller openings of the permeable holes 51 of the steel mesh 5 at the end furthest from the buffer layer 7 prevent rubber particles from flowing with the water into the buffer layer 7, reducing the loss of rubber particles and ensuring the stability of the buffer layer 7. This also reduces the deformation of the sidewalk pavement. Multiple adjacent support blocks 2 can form hidden channels, allowing rainwater to flow through the gravel between the support blocks 2, increasing the permeability of the sidewalk. Simultaneously, the raised support blocks 2 reduce the loss of gravel from the gravel layer 4, ensuring the stability of the gravel layer 4 and reducing the deformation of the sidewalk pavement. The drainage channel 21 increases the space for rainwater to flow between the support plate 1 and the steel mesh 5, thereby increasing the permeability of the sidewalk and providing expansion space to reduce the warping or cracking of the sidewalk surface caused by temperature changes. The four shorter edges of the support plate 1 make it easier for workers to adjust the position and direction of the support plate 1 during installation. After installation, drainage outlets can be formed between multiple adjacent support plates 1, increasing the permeability of the support plate 1 and providing expansion space to reduce the warping or cracking of the sidewalk surface caused by temperature changes.

[0039] When the sidewalk surface lifts up, the position of the leveling block 3 on the support block 2 can be moved to adjust the height of the leveling block 3, thereby adjusting the height of the permeable brick 6, which makes it easier for staff to maintain the sidewalk surface and reduces the maintenance cost of the sidewalk surface.

[0040] This specific embodiment is merely an explanation of this application and is not intended to limit it. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this application.
