Abstract
Description
Technical Field
[0001] This disclosure relates to the field of road paving engineering technology, and in particular to a vehicular sidewalk with a permeable brick pattern. Background Technology
[0002] With the rapid development of modern municipal engineering, sidewalks have become an important part of urban construction. Permeable bricks are widely used in sidewalk paving, offering the advantage of aesthetics but also disadvantages such as lower load-bearing capacity and susceptibility to loosening and damage. For example, the raw materials used in permeable bricks (low-strength cement, clay-containing aggregates) and the low-temperature rapid-firing process result in poor brick density and low compressive strength. While the internal porous structure facilitates water permeability, it weakens the overall load-bearing capacity. Uneven foundations during construction, shrinkage stress from rigid paving materials, or the lack of expansion joints exacerbate uneven stress on the bricks, further compounded by illegal vehicle traffic. This significantly shortens the lifespan of sidewalks, particularly in rural areas. Therefore, this technical solution aims to increase the load-bearing capacity of sidewalks, ensuring vehicular traffic while maintaining an aesthetically pleasing appearance, extending their lifespan, and reducing maintenance costs. Utility Model Content
[0003] To achieve the above objectives, this technical solution proposes a vehicular pedestrian walkway with a permeable brick pattern. It not only has good load-bearing capacity for concrete pavement, ensuring undamaged vehicle passage, but also has the beautiful appearance of ordinary pedestrian walkways, is quick to construct, and is not prone to cracking or damage.
[0004] According to one aspect of this disclosure, a drivable permeable brick-patterned sidewalk is provided, comprising:
[0005] The roadbed is excavated along the length of the sidewalk.
[0006] The curbstone includes a vertical curbstone located on the inner side of the roadbed near the highway and a flat curbstone located on the inner side of the roadbed away from the highway.
[0007] The crushed stone layer is laid at the bottom of the roadbed between the vertical and horizontal curb stones;
[0008] A steel mesh layer is laid on top of the crushed stone layer;
[0009] A concrete layer, which is poured on top of the steel mesh layer, and the upper surface of the concrete layer is flush with the top surface of the edging stone and the flat edging stone.
[0010] The concrete layer is made of 200mm thick C30 concrete. During the intermediate setting stage, a release powder layer is spread and smoothed on the surface of the concrete layer. Then, a mold with a permeable brick pattern is laid and uniformly hammered. After the mold with the permeable brick pattern is removed, expansion joints are cut at intervals along the length of the sidewalk in the concrete layer. After the concrete layer is cleaned, a sealant layer is applied.
[0011] Furthermore, during the initial setting stage of the concrete layer, a reinforcing powder layer is evenly spread and smoothed on the surface. 5 kg of reinforcing powder is evenly spread per square meter, and the powder is spread, smoothed, and finished in three stages. The reinforcing powder penetrates 1-3 mm into the surface of the concrete layer.
[0012] Furthermore, the crushed stone layer is made of 100mm thick secondary crushed stone.
[0013] Furthermore, the bidirectional steel mesh layer adopts a bidirectional steel mesh structure with a spacing of 10 cm and a spacing of 200 mm. Several pads are evenly provided at the bottom of the steel mesh layer to raise the steel mesh layer by 20-30 mm. When pouring concrete, the steel mesh layer is embedded into the bottom of the concrete layer.
[0014] Furthermore, side channels are excavated on both sides of the road channel corresponding to the curb stones and flat curb stones. The width of the side channels is greater than the thickness of the curb stones and flat curb stones. A concrete cushion layer is poured in the side channels, and the curb stones and flat curb stones are placed on the concrete cushion layer.
[0015] Furthermore, the concrete cushion layer is made of 150mm thick C20 concrete.
[0016] Furthermore, the crushed stone layer is made of 100mm thick secondary crushed stone.
[0017] Furthermore, the expansion joints are cut every 6 meters along the length of the sidewalk, with a cutting depth of 200mm.
[0018] This utility model discloses a vehicular pedestrian walkway with a permeable brick pattern. Its advantages are as follows: This solution involves first laying a layer of crushed stone at the bottom of the walkway between the vertical and horizontal curb stones, then laying a layer of reinforcing mesh on top of the crushed stone layer, followed by pouring a concrete layer. Finally, a permeable brick pattern mold, evenly hammered onto the concrete layer, is used to press the pattern onto the concrete, thus creating the permeable brick pattern. Compared to traditional pedestrian walkways that use permeable bricks, this solution achieves faster construction and saves time by pouring concrete.
[0019] A layer of crushed stone is first laid at the bottom of the roadbed, followed by a layer of reinforcing mesh. The crushed stone layer provides a solid foundation, offering uniform and stable support for pedestrian walkways. The shape and size of the crushed stone particles help to distribute and transfer loads, enhancing the overall load-bearing capacity. During the pouring of the concrete layer, the reinforcing mesh is embedded at the bottom of the pedestrian walkway concrete, increasing the road surface's load-bearing capacity and also providing crack resistance. Therefore, this avoids the problem of existing permeable brick pavements easily crushing when vehicles drive on them.
[0020] By pressing a pattern resembling permeable bricks onto the concrete pavement, a pattern resembling permeable bricks is created, giving it the appearance of permeable bricks. Applying a sealant layer to the surface of the concrete layer with the pattern further prevents rainwater from seeping into the concrete layer, thus extending the pavement's service life.

[0024] The technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are also within the scope of protection of this disclosure.
[0025] Please refer to Figure 1This is a specific embodiment of a vehicular permeable brick-patterned sidewalk disclosed in this technical solution. In this embodiment, the sidewalk is paved with a trench dug along the length of the sidewalk. A vertical curb stone 1 is provided on the inner side of the trench near the road, and a horizontal curb stone 2 is provided on the inner side of the trench away from the road. A layer of crushed stone 3 is laid at the bottom of the trench between the vertical curb stone 1 and the horizontal curb stone 2. A reinforcing mesh layer 4 is laid on top of the crushed stone layer 3, and a concrete layer 5 is poured on top of the reinforcing mesh layer 4. The upper surface of the concrete layer 5 is flush with the top surfaces of the vertical curb stone 1 and the horizontal curb stone 2. The crushed stone layer 3 provides a solid foundation, providing uniform and stable support for vehicles crossing the sidewalk. The particle shape and size of the crushed stone help to disperse and transfer the load, enhancing the overall load-bearing capacity. The concrete layer 5 uses 200mm thick C30 concrete. During the intermediate setting stage of the concrete, when there is no significant moisture, a 150mm × 300mm brick-pattern mold is spread on the concrete and then uniformly hammered using a special stamping hammer. The release powder facilitates smooth demolding of the stamping mold without damaging the concrete surface. Within 36-72 hours after molding, expansion joints should be cut promptly to prevent concrete shrinkage and cracking. 3-4 days after molding, the surface release powder should be cleaned with water or detergent. After the pavement dries, a surface sealant should be applied with a roller to form a sealant layer, providing color protection and maintaining color stability. The sealant used is polyurethane sealant or acrylic / epoxy resin sealing layer. In this scheme, the 100mm pavement of the sidewalk area is 100mm higher than the 200mm pavement on the road side, meeting sidewalk specifications, and is flush with the 300mm pavement on the paved side of the adjacent street.
[0026] In this embodiment, the expansion joint is cut every 6 meters along the length of the sidewalk, with a cutting depth of 200mm.
[0027] In this embodiment, preferably, the crushed stone layer 3 is a 100mm thick two-stage crushed stone, that is, the thickness of the crushed stone layer 3 is 100mm. Two-stage crushed stone refers to crushed stone mixture grouped according to a specific particle size range. Usually, the crushed stone is pre-screened into two main particle size ranges, for example: coarse particle size: such as 37.5mm~19mm6; fine particle size: such as 19mm~4.75mm (including stone chips). The mixing ratio: the two types of crushed stone must be mixed in a standard ratio (such as coarse particles dominating and fine particles filling the voids). The particle composition must meet the requirements of dense gradation to ensure compressive strength.
[0028] In this embodiment, preferably, the steel mesh layer 4 adopts a two-way steel mesh structure with a spacing of 10 cm and a spacing of 200 mm. Several pads are evenly provided at the bottom of the steel mesh layer 4 to raise the steel mesh layer 4 by 20-30 mm. When pouring concrete, the concrete enters the bottom through the mesh of the steel mesh, and the steel mesh layer 4 is embedded into the bottom of the concrete layer 5, which increases the load-bearing capacity of the road surface and also plays a role in crack resistance.
[0029] In one embodiment, during the initial setting stage, a reinforcing powder layer is evenly spread and smoothed on the surface of the concrete layer 5. 5 kg of reinforcing powder is evenly spread per square meter, applied in three stages, and then smoothed and finished. The reinforcing powder penetrates 1-3 mm into the surface of the concrete layer 5. The reinforcing powder can solidify the concrete components, making it a dense solid, permanently hardening, strengthening, and sealing the concrete, making it less prone to honeycomb-like surface cracks.
[0030] In one embodiment, preferably, side channels are excavated on both sides of the road channel corresponding to the curb stones 1 and 2. The width of the side channels is greater than the thickness of the curb stones 1 and 2. A concrete foundation 6 is poured in the side channels, and the curb stones 1 and 2 are placed on the concrete foundation 6. The concrete foundation 6 is made of 150mm thick C20 concrete, and it provides strong support for the curb stones 1 and 2.
[0031] The various embodiments of this disclosure have been described above. These descriptions are exemplary and not exhaustive, and are not limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is chosen to best explain the principles, practical application, or improvement of the technology in the market, or to enable others skilled in the art to understand the embodiments disclosed herein.
