Description

Technical Field

[0001] The utility model relates to the technical field of road paving, in particular to an environmentally friendly, anti-skid and water-permeable road surface structure. Background Art

[0002] To accelerate the development of sponge cities, restore urban water ecosystems, conserve water resources, enhance urban flood control capabilities, improve the quality of new urbanization, and promote harmonious development between man and nature, the General Office of the State Council issued the "Guiding Opinions on Promoting Sponge City Construction" on October 1, 2015. Through sponge city construction, a comprehensive approach of "infiltration, retention, storage, purification, utilization, and drainage" will be adopted to minimize the impact of urban development on the ecological environment, ensuring that 70% of rainfall is absorbed and utilized locally. By 2020, more than 20% of urban built-up areas will meet this target, and by 2030, more than 80% of urban built-up areas will meet this target. Permeable pavement, as a "seep" structure that quickly infiltrates surface water into the ground during rainfall, is a key form of sponge city development.

[0003] Traditional permeable pavement base uses a large amount of natural gravel. According to statistics based on the base thickness of 0.5m, every 1,000 square meters of permeable pavement requires 1,000 tons of natural gravel, and 50 transport trucks are needed to transport it from the mining source to the construction site. The mining and transportation of natural sand and gravel resources affect the ecological environment and increase carbon emissions.

[0004] Traditional permeable bricks are made from cementitious materials, admixtures, and single-grain aggregates that are mechanically mixed and then pressed into shape. The single-grain aggregates are stacked together to form a skeleton void structure, allowing water to penetrate into the underlying structure. However, as surface water infiltrates, impurities in the water gradually clog the internal voids of the permeable bricks, resulting in a decrease in porosity and a reduction in permeability. Due to their high porosity, recycled aggregate permeable bricks can accumulate large amounts of water. This moisture and porosity also create conditions for the growth of algae and bacteria. During the rainy season and in shady areas, moss and other plants easily grow on the brick surfaces, reducing the anti-slip coefficient and affecting pedestrian comfort. Because permeable bricks lack connections between bricks, the pavement cannot form a single, integrated structure. If the base layer is not compacted enough, rainwater erosion and settlement can easily cause the permeable bricks to break and damage, affecting their appearance and service life.

[0005] There may already be technical means to solve the above problems in the existing technology, but this case intends to provide an alternative or replacement technical solution. Utility Model Content

[0006] In order to solve the problems in the background technology, the present invention is realized through the following technical solutions: an environmentally friendly, non-slip and permeable pavement structure, comprising a base layer of recycled coarse aggregate from construction waste, a recycled aggregate leveling layer and a recycled aggregate permeable brick surface layer;

[0007] The recycled aggregate leveling layer is arranged above the construction waste recycled coarse aggregate base layer, and the recycled aggregate permeable brick surface layer is arranged above the recycled aggregate leveling layer;

[0008] The recycled aggregate permeable brick surface layer is composed of a plurality of permeable bricks;

[0009] Each of the permeable bricks includes a brick body, which includes a length direction and a width direction. A permeable groove is provided in the center of the wall surfaces on both sides of the length direction of the brick body, an embedded groove is provided on the wall surface on one side of the width direction of the brick body, and a protrusion is provided on the wall surface on the other side of the width direction of the brick body. Positioning ribs and positioning grooves are provided on the wall surfaces on both sides of the length direction of the brick body, and the positioning grooves and the positioning ribs are arranged in an staggered manner.

[0017] Beneficial effects

[0018] The utility model provides an environmentally friendly, non-slip, and permeable pavement structure with the following beneficial effects: it comprises a base layer of recycled coarse aggregate from construction waste, a leveling layer of recycled aggregate from construction waste, and a surface layer of recycled aggregate permeable bricks. Composed of recycled aggregate from construction waste, this reduces the use of natural sand and gravel, and the mining and transportation of natural ore resources, thereby saving energy and being low-carbon and environmentally friendly.

[0023] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work shall fall within the scope of protection of the present invention.

[0024] Example: See Figure 1-3 , an environmentally friendly, anti-skid and permeable pavement structure, comprising a base layer 1 of recycled coarse aggregate from construction waste, a recycled aggregate leveling layer 2 and a recycled aggregate permeable brick surface layer 3;

[0025] The recycled aggregate leveling layer 2 is arranged on the construction waste recycled coarse aggregate base layer 1, and the recycled aggregate permeable brick surface layer 3 is arranged on the recycled aggregate leveling layer 2; the recycled aggregate permeable brick surface layer 3 is composed of a plurality of permeable bricks;

[0026] The construction waste recycled coarse aggregate base layer 1 uses recycled aggregate with a particle size of 5 to 25 mm; the recycled aggregate leveling layer 2 uses recycled aggregate with a particle size of 2 to 5 mm; multiple permeable bricks are spliced ​​into a recycled aggregate permeable brick surface layer 3, which is formed by vibration pressure, and the permeable bricks use recycled aggregate with a particle size of 3 to 8 mm;

[0027] This pavement structure uses recycled aggregate from construction waste to replace natural crushed stone and natural sand and gravel, which reduces the mining of natural mineral resources, protects the environment, and reduces carbon emissions;

[0028] Each permeable brick includes a brick body 31. The brick body 31 includes a length direction and a width direction. A permeable groove 32 is provided at the center of the wall surface of both sides in the length direction of the brick body 31. An embedded groove 33 is provided on one wall surface in the width direction of the brick body 31. A protrusion 34 is provided on the wall surface of the other side in the width direction of the brick body 31. Positioning ribs 35 and positioning grooves 36 are provided on both sides of the wall surface in the length direction of the brick body 31. The positioning grooves 36 and the positioning ribs 35 are arranged in a staggered manner. Anti-slip ribs 37 are provided on the upper wall surface of the brick body 31.

[0029] When splicing permeable bricks, the embedded groove 33 of one permeable brick is matched with the protrusion 34 of another permeable brick, and the positioning rib 35 and positioning groove 36 of one permeable brick are matched with the positioning rib 35 and positioning groove 36 of another permeable brick to form an interlocking structure, thereby achieving the splicing of multiple permeable bricks and improving the integrity of the permeable brick pavement structure, which is conducive to dispersing the pressure on the pavement, reducing pavement damage, and increasing the service life of the pavement. The interlocking structure improves the integrity of the permeable brick surface layer and enhances walking comfort and safety.

[0030] After multiple permeable bricks are spliced ​​together, the area formed by the permeable grooves 32 is easy for water to penetrate. Rainwater and surface water can quickly penetrate into the recycled aggregate leveling layer 2 of the permeable pavement and the recycled coarse aggregate base layer 1 of construction waste. The permeable bricks form a double permeable structure, which is permeable through the voids formed by the internal skeleton void structure and the brick body 31 formed by the permeable grooves 32. This improves the permeability efficiency of the permeable bricks. In addition, the structural permeability can extend the permeability time of the permeable bricks and increase the service life of the permeable bricks.

[0031] The anti-slip ribs 37 on the upper wall of the brick body 31 can improve the anti-slip performance of the permeable brick surface layer, increase the anti-slip coefficient, and enhance the walking comfort and safety of pedestrians;

[0032] As a preferred embodiment, further, the thickness of the construction waste recycled coarse aggregate base layer 1 is 40 to 60 cm;

[0033] As a preference, further, the thickness of the recycled aggregate leveling layer 2 is 5 mm;

[0036] As a preferred embodiment, the embedded groove 33 has a length of 5 cm and a depth of 3 cm, and the protrusion 34 has a length of 5 cm and a protrusion depth of 3 cm.
