Abstract
Description
Technical Field
[0001] This utility model relates to the field of paving stone technology, specifically a permeable ecological paving stone. Background Technology
[0002] With the acceleration of urbanization, traditional hard paving materials (such as concrete and stone tiles) are gradually being replaced by permeable ecological paving materials due to their poor permeability and low ecological benefits. Existing permeable pavers mainly achieve rainwater infiltration through their porous structure. However, while existing ecological paving stones can achieve partial permeability, their simple design of grass planting areas and drainage channels often leads to decreased permeability due to soil compaction or blockage by impurities, and the low survival rate of grass planting makes it difficult to form a stable ecological effect. Furthermore, traditional pavers rely on a single permeable layer or gaps for drainage, which easily leads to water accumulation during heavy rains, increasing surface runoff and even eroding the foundation. While some designs include drainage channels, they lack modular, coordinated drainage paths, resulting in low water dispersion efficiency. Moreover, the paving modules are often fixed with simple interlocking or mortar, which can easily lead to displacement and warping over time, affecting overall flatness and the continuity of drainage channels. Summary of the Invention
[0003] The technical problem to be solved by this utility model is to provide a permeable ecological paving stone to solve the problems of the existing paving stone's simple structure and insufficient aesthetics, so as to achieve efficient drainage while ensuring the ecological benefits of the paved area.
[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a permeable ecological paving stone, including a paving stone module, wherein a groove is provided in the middle of the paving stone module, a partition is provided in the groove, and a through hole is provided on the partition.
[0005] The paving stone module is provided with drainage grooves on both sides. When two adjacent paving stone modules are spliced together, the drainage grooves on the two paving stone modules form a drainage channel.
[0006] The side wall of the paving stone module is provided with a water passage hole, which connects the groove body and the drainage channel.
[0007] In a preferred embodiment, the paving stone module is provided with inter-module connection grooves around its perimeter, and adjacent paving stone modules are finally connected and fixed by connectors inserted into the inter-module connection grooves.
[0008] In a preferred embodiment, the top surface of the groove of the paving stone module is provided with a cover plate, and the cover plate is provided with multiple slots.
[0009] In a preferred embodiment, the inner sides of the paving stone module are provided with step grooves, and the cover plate is placed on the step grooves.
[0010] In a preferred embodiment, the inter-module connection slot of a single module is an "L" shaped slot structure, the inter-module connection slots of two adjacent paving stone modules form a "U" shaped slot, the connector is a "U" shaped component, and the connector is inserted into the "U" shaped slot formed by the two inter-module connection slots.
[0011] In a preferred embodiment, the connector is provided with a tension spring, and the two ends of the tension spring are respectively connected to the inner walls on both sides of the connector.
[0012] In a preferred embodiment, a gauze pad is laid in the groove below the partition.
[0013] The permeable ecological paving stone provided by this utility model, by adopting the above-mentioned structure, has the following beneficial effects:
[0014] (1) The groove is equipped with partitions and through holes, which, together with the strip hole structure of the cover plate, form a multi-layer permeable path. Planting soil can be filled above the partitions and grass can be planted. The grass grows upward through the strip holes, while rainwater seeps downward through the through holes, avoiding soil loss and clogging of the channels, achieving a dynamic balance between water permeability, water storage and grass planting functions, and significantly improving ecological benefits.
[0015] (2) The drainage channels on both sides of the paving stone module form a continuous drainage channel after splicing. Combined with the guiding effect of the water passage holes on the side wall, the rainwater accumulated in the groove can be quickly introduced into the drainage channel, forming a three-dimensional drainage network of "vertical infiltration + horizontal drainage", which can effectively cope with the instantaneous runoff of rainstorms and reduce the risk of ground water accumulation and foundation erosion.
[0016] (3) The modules are fixed by inserting "L"-shaped connecting grooves and "U"-shaped connectors, and with the elastic tension of the tension springs, the displacement resistance and seismic resistance of the modules are enhanced, ensuring the long-term continuity of the drainage channel. At the same time, the modular splicing does not require mortar fixing, which makes the construction efficient and convenient for local replacement and maintenance;
[0017] (4) The gauze pad layer installed under the partition can filter the mud and sand impurities brought in by rainwater, prevent the drainage channel from being blocked, and the open design of the groove body makes it easy to clean the sediment regularly, reducing operation and maintenance costs.

[0024] like Figure 1-4 Among them, a permeable ecological paving stone includes a paving stone module 1, wherein a groove 101 is provided in the middle of the paving stone module 1, a partition 2 is provided in the groove 101, and a through hole 3 is provided on the partition 2.
[0025] The paving stone module 1 is provided with drainage grooves 9 on both sides. When two adjacent paving stone modules 1 are spliced together, the drainage grooves 9 on the two paving stone modules 1 form a drainage channel.
[0026] The paving stone module 1 has a water passage hole 10 on its side wall, which connects the groove body 101 and the drainage groove 9.
[0027] In a preferred embodiment, the paving stone module 1 is provided with inter-module connection grooves 4 around its perimeter, and two adjacent paving stone modules 1 are finally connected and fixed by connectors 7 inserted into the inter-module connection grooves 4.
[0028] In a preferred embodiment, the top surface of the groove 101 of the paving stone module 1 is provided with a cover plate 6, and the cover plate 6 is provided with multiple slots.
[0029] In a preferred embodiment, the inner sides of the paving stone module 1 are provided with step grooves 5, and the cover plate 6 is placed on the step grooves 5.
[0030] In a preferred embodiment, the inter-module connection slot 4 of a single module is an "L" shaped slot structure, the inter-module connection slots 4 of two adjacent paving stone modules 1 form a "U" shaped slot, the connector 7 is a "U" shaped component, and the connector 7 is inserted into the "U" shaped slot formed by the two inter-module connection slots 4.
[0031] In a preferred embodiment, the connector 7 is provided with a tension spring 8, and the two ends of the tension spring 8 are respectively connected to the inner walls on both sides of the connector 7.
[0032] In a preferred embodiment, a gauze pad 11 is laid in the groove 101 below the partition 2.
[0033] In the above structure, the paving stone module 1 is made of precast concrete or recycled aggregate, and has an overall square structure (e.g., 500mm × 500mm × 80mm). A rectangular groove 101 with a depth of 50mm is provided in the center of the paving stone module 1, and a permeable gauze pad 11 (made of non-woven fabric or nylon mesh) is laid at its bottom. A partition 2 is fixedly installed inside the groove 101. The partition 2 is a perforated plastic plate or metal mesh plate with a thickness of 5mm. The partition 2 divides the groove 101 into upper and lower layers: the upper layer is filled with planting soil and sown with grass seeds, and the lower layer serves as a water storage layer. Multiple through holes 3 (5mm in diameter, 20mm apart) are evenly distributed on the partition 2 for rainwater infiltration.
[0034] The four sides of the paving stone module 1 are provided with inter-module connecting grooves 4. The connecting grooves 4 are "L"-shaped grooves with a depth of 10mm. When two adjacent paving stone modules 1 are spliced, their corresponding two "L"-shaped connecting grooves 4 combine to form a "U"-shaped groove. A "U"-shaped metal connector 7 (e.g., made of 304 stainless steel) is inserted. A tension spring 8 is welded between the two inner side walls of the connector 7. In its natural state, the tension spring 8 causes the two side walls of the connector 7 to elastically clamp inward, thereby tightly locking into the "U"-shaped groove and achieving a stable connection between the modules.
[0035] The inner side of the top opening of the groove 101 of the paving stone module 1 is provided with stepped grooves 5, the depth of which is 3mm, for overlapping the cover plate 6. The cover plate 6 is a steel grid or plastic grid with strip holes (the strip holes are radial). The cover plate 6 covers the groove 101, protects the grass planting area and allows grass leaves to grow through the strip holes, while also serving as a bearing surface.
[0036] Drainage channels 9 are symmetrically opened on both sides of the paving stone module 1. The drainage channels 9 have a semi-circular cross section (radius 10mm). After adjacent modules are spliced, the two semi-circular drainage channels 9 are combined to form a complete circular drainage channel. Water passage holes 10 (diameter 8mm) are opened on the side wall of the paving stone module 1. One end of the water passage hole 10 is connected to the water storage layer of the groove body 101, and the other end is connected to the drainage channel 9, which is used to guide rainwater in the water storage layer into the drainage channel.
[0037] The construction and operation process of permeable ecological paving stones based on the above structure is as follows:
[0038] Foundation treatment: Lay a layer of graded crushed stone (150mm thick) on the foundation, compact it, and then cover it with permeable geotextile.
[0039] Module assembly: Arrange the paving stone modules 1 in rows and columns, and fix them by inserting the connectors 7 into the connecting slots 4 of the adjacent modules to form a continuous paving surface.
[0040] Planting grass and installing cover plates: Fill the groove 101 above the partition plate 2 with planting soil and sow grass seeds, then attach the cover plate 6 to the step groove 5.
[0041] Drainage test: Rainwater enters the groove 101 through the slots in the cover plate 6, and some seeps down to the water storage layer through the through holes 3 in the partition plate 2, then flows into the drainage trough 9 through the water passage 10, and finally is discharged into the municipal pipe network or recycling system through the drainage channel. Grass roots grow through the slots in the cover plate 6, forming ecological turf.
