Description

Technical Field

[0001] This application relates to the field of municipal road construction materials technology, and in particular to a luminescent permeable brick for sidewalks. Background Technology

[0002] With the acceleration of urbanization, sidewalks, as an important component of urban transportation systems, have received widespread attention for their performance and safety. Traditional sidewalk bricks are mostly made of ordinary concrete, which has the following problems: First, they have poor permeability, easily causing water to accumulate on the road surface during rainfall, affecting pedestrian safety, and rainwater cannot infiltrate into the ground in time, which is detrimental to the urban groundwater cycle; second, they lack active warning functions at night, especially in poorly lit areas, making it difficult for pedestrians and non-motorized vehicles to clearly identify road boundaries, increasing the risk of collisions or falls; third, although some permeable bricks have water permeability, their structural strength is insufficient, and they are prone to damage and breakage after long-term use, resulting in a short service life.

[0003] Therefore, there is an urgent need to design a sidewalk brick that combines high water permeability, long-lasting luminous warning, self-cleaning and adaptive drainage functions to meet the needs of modern urban road construction. Utility Model Content

[0004] To address or partially address the problems existing in related technologies, this application provides a luminescent permeable brick for sidewalks, which can solve the problems of poor permeability, lack of nighttime warning function, insufficient structural strength, untimely drainage during extreme rainfall, and easy dust accumulation and failure of the luminescent structure in traditional sidewalk bricks.

[0005] This application provides a luminescent permeable brick for sidewalks, including a luminescent warning layer 1, a permeable buffer layer 2, and a brick base layer 3; the luminescent warning layer 1, the permeable buffer layer 2, and the brick base layer 3 are arranged sequentially from top to bottom and fixedly connected by a composite molding process, and an adjustable drainage component 4 is provided inside the brick base layer 3.

[0006] The adjustable drainage assembly 4 includes a main drainage pipe 41, an elastic waterstop 42, and a filter screen 43. The main drainage pipe 41 penetrates vertically through the brick base layer 3, with its top contacting the permeable buffer layer 2 and its bottom extending to the outside of the brick base layer 3 and connecting to the sewer pipe through the main drainage pipe. The elastic waterstop 42 is circular and its edge is fixedly connected to the inner wall of the main drainage pipe 41, with a cross-shaped cut in the middle. The filter screen 43 is fixed to the top of the main drainage pipe 41.

[0007] Optionally, in some embodiments, the luminous warning layer 1 includes a transparent wear-resistant base layer 11 and a luminous strip 12. The luminous strip 12 is embedded inside the transparent wear-resistant base layer 11 and is spaced apart along the length of the brick. The upper surface of the transparent wear-resistant base layer 11 is provided with anti-slip texture 13 and self-cleaning guide groove 14.

[0008] Optionally, in some embodiments, the anti-slip texture 13 is a diamond-shaped raised structure, and the self-cleaning guide groove 14 is arranged along the diagonal direction of the brick body, interspersed with the anti-slip texture 13 and connected to the edge of the brick body.

[0009] Optionally, in some embodiments, the permeable buffer layer 2 is made by mixing permeable resin particles, quartz sand and antibacterial agent in a mass ratio of 3:1:0.2, with a thickness of 8-12mm, a permeability coefficient of not less than 2×10⁻³m / s, and the antibacterial agent is nano silver ion antibacterial powder.

[0010] Optionally, in some embodiments, the brick base layer 3 is made of recycled aggregate concrete, with honeycomb permeable holes 31 evenly distributed inside, and a positioning groove 32 is provided at the bottom of the brick base layer 3, with the positioning groove 32 set along the edge of the brick.

[0011] Optionally, in some embodiments, four adjustable drainage components 4 are distributed within the brick base layer 3, located at the four corners of the brick.

[0012] The technical solution provided in this application may include the following beneficial effects: This application features adaptive drainage performance: through the combined design of "honeycomb permeable holes + adjustable drainage components", rainwater infiltration is achieved through the permeable holes during normal rainfall, and rainwater is quickly discharged through the drainage main pipe by the automatic opening and closing of the elastic water-stop plate during extreme rainfall. The permeability coefficient can reach up to 5×10⁻³m / s, effectively avoiding road water accumulation and adapting to different rainfall intensities. This application features a self-cleaning luminous warning function: the self-cleaning guide channel of the luminous warning layer can automatically wash away surface debris with the help of rainwater, ensuring the light transmittance of the luminous strip; the transparent and wear-resistant base layer protects the luminous strip from wear, and the long afterglow light-gathering material enables it to emit light autonomously for 8-12 hours, providing double protection for a long-lasting and stable nighttime warning effect; This application improves antibacterial properties and structural strength: the nano-silver ion antibacterial powder added to the permeable buffer layer inhibits bacterial growth and prevents mold and odor from developing in the bricks; the brick base layer uses recycled aggregate concrete with a compressive strength ≥30MPa, which, combined with the impact resistance of the permeable buffer layer, extends the service life by more than 30%. This application facilitates easy installation and maintenance: the positioning grooves facilitate precise brick laying, reducing construction costs; the filter screen prevents drainage components from clogging, and the self-cleaning design reduces the frequency of manual maintenance, resulting in a 25% reduction in overall operating costs.

[0021] To address the aforementioned issues, this application provides a luminescent permeable brick for sidewalks, which solves the problems of poor permeability, lack of nighttime warning function, insufficient structural strength, untimely drainage during extreme rainfall, and easy dust accumulation and failure of the luminescent structure in traditional sidewalk bricks.

[0022] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0023] See Figure 1-2 The luminous permeable bricks for sidewalks include a luminous warning layer 1, a permeable buffer layer 2, and a brick base layer 3. The luminous warning layer 1, the permeable buffer layer 2, and the brick base layer 3 are arranged sequentially from top to bottom and fixedly connected by a composite molding process. An adjustable drainage component 4 is provided inside the brick base layer 3. Four adjustable drainage components 4 are distributed inside the brick base layer 3 and are located in the four corner areas of the brick.

[0024] The adjustable drainage assembly 4 includes a main drainage pipe 41, an elastic waterstop 42, and a filter screen 43. The main drainage pipe 41 penetrates vertically through the brick base layer 3, with its top contacting the permeable buffer layer 2 and its bottom extending to the outside of the brick base layer 3 and connecting to the sewer pipe through the main drainage pipe. The elastic waterstop 42 is circular and its edge is fixedly connected to the inner wall of the main drainage pipe 41, with a cross-shaped cut in the middle. The filter screen 43 is fixed to the top of the main drainage pipe 41.

[0025] The brick base layer 3 is made of recycled aggregate concrete, with honeycomb permeable holes 31 evenly distributed inside. The bottom of the brick base layer 3 is provided with a positioning groove 32, which is set along the edge of the brick.

[0026] Specifically, the honeycomb permeable holes 31 have a diameter of 3-5mm and a porosity of 25%-30%. The positioning grooves 32 are set along the edge of the brick body and have a depth of 3-5mm. They are used for splicing and positioning when laying bricks. Through the combined design of "honeycomb permeable holes + adjustable drainage components", rainwater can be infiltrated by the permeable holes during normal rainfall. During extreme rainfall, rainwater can be quickly discharged by the drainage main pipe through the automatic opening and closing of the elastic water-stop plate. The permeability coefficient can reach up to 5×10⁻³m / s, effectively avoiding water accumulation on the road surface and adapting to different rainfall intensities. The luminous warning layer 1 is used to realize the night warning function.

[0027] The brick base layer 3, as the main load-bearing structure of the brickwork, is made of recycled aggregate concrete, which not only realizes the recycling of construction waste but also reduces production costs. The base layer has uniformly distributed honeycomb-shaped permeable pores with a pore diameter of 3-5mm and a porosity controlled at 25%-30%. These parameters have been verified through multiple tests to ensure rapid rainwater infiltration while maintaining sufficient compressive strength (≥30MPa) to meet the daily traffic load requirements of the sidewalk.

[0028] The adjustable drainage component 4 is the core component for dealing with extreme rainfall. The main drainage pipe 41 vertically penetrates the brick base layer, is made of ABS engineering plastic, has an inner diameter of 8-10mm, and a wall thickness of 2-3mm. Its top contacts the permeable buffer layer 2, and its bottom extends to the outside of the brick base layer 3, buried in the foundation at the bottom of the brick, allowing rainwater to be directly channeled into the underground drainage system. The elastic waterstop 42 is made of nitrile rubber, with a thickness of 0.8-1.2mm. It is circular, with its edges fixed to the inner wall of the main drainage pipe 41, and has a cross-shaped cut in the center (cut width 1-1.5mm). During normal rainfall, rainwater slowly seeps through the honeycomb-shaped permeable holes 31, while the elastic waterstop 42 remains closed to prevent reverse evaporation of groundwater. During extreme rainfall, the rainwater creates a certain water pressure inside the brick, pushing the cross-shaped cut of the elastic waterstop 42 to open, allowing rainwater to be quickly discharged through the main drainage pipe 41, achieving "normal infiltration +..." It has a dual function of "emergency drainage"; the filter screen 43 is fixed to the top of the drain pipe 41, which can filter debris and prevent the drain pipe 41 from getting clogged.

[0029] To facilitate precise positioning during brick laying, a positioning groove 32 is provided at the bottom of the brick base layer 3. The positioning groove 32 is set along the edge of the brick and has a depth of 3-5mm. During laying, the positioning groove 32 of the brick can be used in conjunction with a special positioning strip to effectively prevent brick displacement and improve laying efficiency and road surface smoothness.

[0030] In some implementations, see Figure 3The luminous warning layer 1 includes a transparent wear-resistant base layer 11 and a luminous strip 12. The luminous strip 12 is embedded inside the transparent wear-resistant base layer 11 and is spaced apart along the length of the brick. The upper surface of the transparent wear-resistant base layer 11 is provided with anti-slip texture 13 and self-cleaning guide groove 14. The anti-slip texture 13 is a diamond-shaped raised structure. The self-cleaning guide groove 14 is arranged along the diagonal direction of the brick, and is distributed interspersed with the anti-slip texture 13 and connected to the edge of the brick.

[0031] Specifically, the width of the luminous strip 12 is 5-8mm, and it is made of long afterglow light-gathering material. The anti-slip texture 13 is a diamond-shaped raised structure with a raised height of 1-2mm and a spacing of 5-8mm between adjacent raised sections. The self-cleaning guide groove 14 is set along the diagonal direction of the brick body, with a depth of 0.5-1mm and a width of 2-3mm. It is staggered with the anti-slip texture 13 and connected to the edge of the brick body.

[0032] The luminous warning layer 1 is the core structure for achieving nighttime safety warning functions, including a transparent wear-resistant base layer 11, a luminous strip 12, and a self-cleaning guide channel 14. The transparent wear-resistant base layer 11 has high strength, high wear resistance (wear resistance ≤0.1g / 1000 revolutions), and good light transmittance, which can protect the internal luminous strip 12 from wear and ensure that the luminous effect of the luminous strip 12 can be clearly transmitted to the road surface.

[0033] The luminous strips 12 are embedded inside the transparent wear-resistant base layer 11, spaced apart along the length of the brick, with a width of 5-8mm, and are made of long-afterglow light-gathering material. This material can absorb sunlight or lamp energy during the day and emit light autonomously at night without additional power supply. The luminescence lasts for 8-12 hours, and the brightness meets road warning requirements, effectively guiding pedestrians to identify road boundaries and reducing the risk of nighttime travel.

[0034] The self-cleaning drainage channel 14 is an innovative design to solve the problem of water and dust accumulation in the luminous structure. It is set along the diagonal direction of the brick body, with a depth of 0.5-1mm and a width of 2-3mm, and is distributed interspersed with the diamond-shaped anti-slip texture 13 and connected to the edge of the brick body. During rainfall, rainwater can flow along the self-cleaning drainage channel 14, washing away dust, fallen leaves and other debris on the surface of the luminous warning layer 1, and guiding it into the drainage gaps at the edge of the brick body, achieving "rainwater self-cleaning". This eliminates the need for frequent manual cleaning and ensures the long-term stability of the light transmittance and luminous effect of the luminous strip 12. At the same time, the self-cleaning drainage channel 14 can further enhance the drainage capacity of the brick body and prevent rainwater from forming a water film on the surface of the luminous warning layer 1.

[0035] In addition, the upper surface of the luminous warning layer 1 is pressed with a diamond-shaped raised anti-slip texture 13, with a raised height of 1-2mm and a spacing of 5-8mm between adjacent raised sections. The anti-slip texture 13 can increase the friction between the soles of pedestrians' shoes and the brick surface, especially in rainy or wet environments, effectively preventing pedestrians from slipping and further improving the safety of pedestrian crossings.

[0036] In some embodiments, the permeable buffer layer 2 is made by mixing permeable resin particles, quartz sand and antibacterial agent in a mass ratio of 3:1:0.2, with a thickness of 8-12mm, a permeability coefficient of not less than 2×10⁻³m / s, and the antibacterial agent is nano silver ion antibacterial powder.

[0037] Specifically, the permeable buffer layer 2 is located between the luminous warning layer 1 and the brick base layer 3, serving as a transition buffer, providing secondary permeability, and acting as an antibacterial agent. This layer is made of permeable resin particles, quartz sand, and nano-silver ion antibacterial powder mixed in a mass ratio of 3:1:0.2. The permeable resin particles are made of highly elastic polyurethane material, possessing excellent permeability and impact resistance, which can alleviate the impact of pedestrians on the brick body and extend its service life. The addition of quartz sand further enhances the structural strength of the buffer layer. The nano-silver ion antibacterial powder inhibits bacterial growth, preventing long-term rainwater infiltration from causing mold and odor inside the brick body, making it particularly suitable for humid environments. The thickness of the permeable buffer layer 2 is designed to be 8-12mm, and its permeability coefficient, as tested, is not less than 2×10⁻³m / s, allowing it to quickly receive and drain rainwater infiltrating from the luminous warning layer 1, preventing rainwater accumulation between layers.
