Description

Technical Field

[0001] This utility model relates to the field of ecological paving stone technology, specifically to an ecological permeable paving stone. Background Technology

[0002] Eco-friendly paving stones, as an environmentally friendly paving material, have been widely used in landscape projects such as plazas and sidewalks in recent years. Traditional eco-friendly paving stones are mostly made by mixing and pressing natural stone fragments with resin. Although they have a certain degree of permeability, the surface permeable holes are mostly designed in a straight cylindrical shape, resulting in uneven diffusion of rainwater after infiltration. In addition, adjacent stone slabs are often glued together, which has weak resistance to settlement. After being driven over by vehicles, they are prone to misalignment and warping.

[0003] The existing stone slab splicing structure is complex, has low construction efficiency and is difficult to maintain, and rainwater infiltrates and diffuses unevenly.

[0004] Therefore, it is particularly important to design an ecological permeable paving stone to overcome the above-mentioned technical defects and improve the overall practicality. Utility Model Content

[0024] For examples, please refer to Figure 1-3 This utility model provides a technical solution:

[0025] An ecological permeable paving stone includes a first slab assembly 1, a second slab assembly 2 on one side of the first slab assembly 1, and both the first slab assembly 1 and the second slab assembly 2 include a base plate 3. The surface of the base plate 3 has a plurality of micropores 301, and the bottom of the micropores 301 has a plurality of funnel-shaped permeable channels 302. The bottom of the base plate 3 has a mounting plate 303, and the interior of the mounting plate 303 has a grid-shaped water distribution channel 304. The first slab assembly 1 has a plurality of fixing cylinders 4, with symmetrical slots 401 at the top and bottom of each fixing cylinder 4. The interior of each fixing cylinder 4 has a sliding rod 402, with symmetrical limiting rods 403 at the top and bottom of each sliding rod 402. One end of each sliding rod 402 has a symmetrical hinge seat 404, and the hinge seat 404 has a positioning rod 405. One end of each positioning rod 405 has a positioning plate 406, and the bottom end of each positioning rod 405 has a return spring 407. The second slab assembly 2 has a plurality of limiting cylinders 5, with limiting devices inside each limiting cylinder. The cavity 501 and the limiting cylinder 5 are respectively provided with limiting holes 502 at the top and bottom. Rainwater seeps quickly down through the honeycomb micropores 301 on the surface of the substrate 3 and flows into the funnel-shaped permeable channel 302 at the bottom. The bottom opening is 5-8mm wide, which breaks the capillary effect and accelerates drainage. After the water flows through the permeable channel, it enters the grid-shaped water distribution tank 304 of the mounting plate 303. The inclined tank wall guides the water flow to diffuse radially and evenly to the lower foundation, avoiding local water accumulation. When it is necessary to splice the stone slabs, the first stone slab group is pulled forcefully. Part 1 slide rod 402, at this time the limiting rod 403 disengages from the inside of the limiting seat 408, aligns the positioning rod 405 with the limiting cylinder 5 of the second stone slab assembly 2, press down the positioning plate 406, so that it slides along the limiting cavity 501 until the positioning plate 406 passes through the inside of the limiting hole 502, limiting the position of the two stone slabs. The recycled ceramic substrate 3 is pressure-resistant and freeze-resistant, and the engineering plastic mounting plate 303 is corrosion-resistant and weight-reducing, which together ensure the long-term stability of the structure under rainwater infiltration and human and vehicle loads.

[0026] The funnel-shaped permeable channel 302 has a top aperture of 0.5–2 mm and a bottom flared aperture of 5–8 mm. The micropores 301 are distributed in a honeycomb array on the surface of the substrate 3. The small aperture at the top intercepts sediment, while the large aperture at the bottom accelerates drainage. The substrate 3 is made of recycled ceramic aggregate sintered together. The mounting plate 303 is made of high-strength engineering plastic through one-piece injection molding. The engineering plastic injection molding mounting plate reduces weight, increases resistance to acid and alkali corrosion, and extends service life. The slots 401 have symmetrical limiters at both ends. The seat 408 and the limiting rod 403 are connected by a snap-fit ​​mechanism. The position of the sliding rod is limited by the snap-fit ​​mechanism between the limiting seat 408 and the limiting rod 403 to prevent the sliding rod from disengaging. The inner wall of the limiting hole 502 is inclined to facilitate the fitting between the limiting hole 502 and the positioning plate 406. The depth of the grid-shaped water distribution tank 304 is 1 / 3 to 1 / 2 of the thickness of the mounting plate 303, and the inclination angle of the tank wall is 10° to 15°. The inclination angle guides the radial diffusion of the water flow and improves the water distribution efficiency.

[0027] The working process of this utility model is as follows: When using this type of ecological permeable paving stone, rainwater first seeps quickly down through the honeycomb-shaped micropores 301 on the surface of the substrate 3, flowing into the bottom of the funnel-shaped permeable channel 302 with a 5-8mm wide opening at the bottom to break capillary action and accelerate drainage. After the water flows through the permeable channel, it enters the grid-shaped water distribution trough 304 of the mounting plate 303. The inclined trough wall guides the water flow to diffuse radially and evenly to the lower foundation, avoiding local water accumulation. When it is necessary to splice the stone slabs, the sliding rod 402 of the first stone slab assembly 1 is pulled forcefully. At this time, the limiting rod 403 disengages from the inside of the limiting seat 408, aligning the positioning rod 405 with the limiting cylinder 5 of the second stone slab assembly 2. The positioning plate 406 is pressed down, causing it to slide along the limiting cavity 501 until the positioning plate 406 penetrates through the inside of the limiting hole 502, limiting the position of the two stone slabs. The recycled ceramic substrate 3 is pressure-resistant and freeze-resistant, and the engineering plastic mounting plate 303 is corrosion-resistant and weight-reducing, working together to ensure the long-term stability of the structure under rainwater infiltration and human and vehicle loads.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
