Description

Technical Field

[0001] This utility model relates to the field of artificial turf, and more specifically, to a hollow drainage artificial turf. Background Technology

[0002] Artificial turf is a simulated grass made from synthetic fibers through processes such as drawing, weaving, and tufting. It closely resembles natural grass in appearance and is commonly used in sports fields, landscaping, and rooftop gardens. Its main materials include polyethylene (PE), polypropylene (PP), and nylon (PA). PE grass fibers are soft and comfortable, suitable for landscaping; PP grass fibers are wear-resistant and inexpensive, commonly used in running tracks; and nylon grass fibers are high-strength, suitable for professional sports fields.

[0003] Traditional artificial turf drainage structures often rely on simple drainage holes in the base or a layer of gravel at the bottom. In actual use, this type of design has revealed the problem of low drainage efficiency (rainwater can only seep vertically through a single small hole, and the water flow is dispersed in the gravel base, unable to quickly converge, ultimately leading to low drainage efficiency). Especially in heavy rainfall or high-frequency use scenarios, surface water is difficult to drain quickly, which not only makes the field slippery and affects the user experience, but may also cause mold growth at the roots of the artificial turf fibers and accelerated aging of the base material due to long-term water accumulation.

[0004] Therefore, in order to solve the above-mentioned technical problems, this application proposes a hollow drainage artificial turf. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a hollow drainage artificial turf.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a hollow drainage artificial turf. The base has multiple regularly arranged through holes A on its top, and the interior is hollow. The through holes A are connected to the interior of the base. Drainage grooves are provided on both sides of the bottom of the base. The surface layer is located above the base and has multiple through holes B aligned with through holes A. Artificial grass fibers are provided on the surface layer.

[0007] Preferably, a filter screen can be detachably connected to the opening of the through hole A.

[0008] Preferably, the inner bottom wall of the base is connected to its top by a support column.

[0009] Preferably, the inner bottom wall of the substrate is provided with a slope that guides water entering the substrate toward a drainage channel.

[0010] Preferably, the top of the surface layer of the face skin is provided with multiple anti-slip protrusions.

[0011] Preferably, the through hole A and through hole B have the same diameter and are both round holes.

[0012] Preferably, the anti-slip protrusion is truncated cone-shaped with micropores at the top, and the micropores are filled with anti-slip particles.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. When rainwater or stagnant water falls onto the surface of the turf, the water flows directly into the through-hole A at the top of the substrate through the through-hole B on the surface of the turf. Since the substrate is hollow and the through-hole A is connected to the interior of the substrate, the water can quickly converge and flow laterally within the hollow space of the substrate, and finally be discharged through the drainage channels on both sides of the bottom of the substrate. The through-hole B on the surface of the turf and the through-hole A on the substrate are aligned with each other to form multiple vertical drainage channels that run vertically through the substrate, ensuring that surface water can quickly seep into the interior of the substrate. The hollow structure of the substrate and the drainage channels at the bottom form a lateral flow path, allowing the water to converge and be discharged efficiently, thereby preventing water from stagnating on the surface of the turf or in the substrate, and solving the problem of low drainage efficiency in traditional artificial turf. 2. In this utility model, the anti-slip protrusion is a truncated cone-shaped protrusion structure. Compared with traditional flat or columnar protrusions, its inclined surface can disperse contact pressure, reduce protrusion wear, and extend service life. The micropores opened at the top provide a fixed space for the anti-slip particles. When the anti-slip particles are subjected to external friction, they can form multi-directional resistance, further enhancing the surface anti-slip effect. Especially in wet or muddy environments, the irregular surface of the particles can pierce the water film, increase contact friction, and effectively prevent slipping. 3. The filter screen in this utility model can intercept grass fibers, mud, leaves and other impurities, prevent drainage channels from being blocked, and ensure that rainwater can be continuously discharged quickly through through holes B and through holes A; the detachable design greatly improves the convenience of maintenance. When the filter screen is blocked by impurities and affects drainage, there is no need to disassemble the entire artificial turf. You only need to easily remove the filter screen for cleaning or replacement, which significantly reduces the difficulty and cost of maintenance. Attached Figure Description

[0016] like Figure 1-5 As shown, this utility model provides a hollow drainage artificial turf, including... The base 1 has multiple regularly arranged through holes A101 on its top, and the interior is hollow. The through holes A101 are connected to the interior of the base 1. Drainage grooves 102 are provided on both sides of the bottom of the base 1. The surface layer 2 is located above the base 1 and has multiple through holes B201 aligned with the through holes A101. Artificial grass fibers are provided on the surface layer 2 (artificial grass fibers are provided in other parts except through holes B201; the artificial grass fibers are not shown in the attached figure for clarity).

[0017] When rainwater or accumulated water falls onto the surface layer 2, the water flows directly into the through-hole A101 at the top of the base 1 through the through-hole B201 on the surface layer 2. Since the base 1 is hollow and the through-hole A101 is connected to the interior of the base 1, the water can quickly converge and flow laterally within the hollow space of the base 1, and finally be discharged through the drainage channels 102 on both sides of the bottom of the base 1. The through-hole B201 of the surface layer 2 and the through-hole A101 of the base 1 are aligned with each other, forming multiple vertical drainage channels that run vertically through the surface. This ensures that surface water can quickly seep into the interior of the base 1. The hollow structure of the base 1 and the bottom drainage channels 102 constitute a lateral flow path, allowing the water to converge and be discharged efficiently, thereby preventing water from stagnating in the surface layer 2 or the base 1. This achieves a three-dimensional drainage system of "vertical infiltration + lateral convergence", which is far more efficient than the single vertical infiltration of traditional solutions.

[0018] Furthermore, firstly, both through holes A101 and B201 have the same diameter, being circular holes. Designing through holes A101 and B201 as circular holes of the same diameter enables precise adaptation and efficient operation of the artificial turf drainage structure. On one hand, the circular holes of the same diameter allow the through holes on the surface layer and the base to be completely aligned, forming a vertically continuous drainage channel. This eliminates drainage obstruction caused by misalignment of the hole diameters, allowing rainwater to flow directly vertically from the through hole B201 on the surface layer 2 into the channel of the base 1, greatly improving drainage efficiency. On the other hand, compared to irregularly shaped holes, circular channels are simpler to design and manufacture, reducing manufacturing costs. Moreover, the circular structure distributes stress evenly, making it less prone to deformation when subjected to external forces such as trampling, ensuring the stability and durability of the drainage channel.

[0019] Secondly, each of the openings of the through hole A101 is detachably connected to a filter screen 103. The filter screen 103 can intercept grass clippings, mud, leaves and other impurities, preventing drainage channel blockage and ensuring that rainwater can be continuously discharged quickly through the through holes B201 and A101. The detachable design greatly improves the convenience of maintenance. When the filter screen 103 is blocked by impurities and affects drainage, there is no need to disassemble the entire artificial turf. You can simply remove the filter screen 103 for cleaning or replacement, which significantly reduces the difficulty and cost of maintenance.

[0020] Furthermore, the inner bottom wall of the base 1 is connected to its top via support columns 3. This design effectively enhances the structural stability and load-bearing capacity of the base 1. On one hand, the support columns 3 form a three-dimensional support frame within the hollow structure of the base 1, preventing the hollow area from collapsing or deforming due to external loads such as foot traffic or equipment crushing. This ensures that the through-hole A101 and the through-hole B201 of the surface layer 2 remain aligned, maintaining the smooth flow of the vertical drainage channel. On the other hand, the support columns 3 can evenly distribute the pressure borne by the top to the entire base 1, reducing material fatigue or damage caused by localized stress concentration. This is especially suitable for high-frequency use scenarios such as sports fields. In addition, the inner bottom wall of the base 1 is equipped with a slope 4 that guides water entering the base 1 towards the drainage channel 102, which can significantly improve the drainage efficiency and reliability of the artificial turf. The slope 4 structure can make full use of gravity to automatically guide rainwater entering the base 1 to the drainage channel 102, avoiding water accumulation inside the base 1 and effectively reducing problems such as corrosion and mold of the base 1 material caused by water accumulation. Compared with the traditional horizontal base 1, the slope 4 design shortens the flow path of rainwater in the base 1 and speeds up the drainage speed. Especially in heavy rain, it can quickly drain the water in the base 1 and ensure that the lawn can be quickly restored and used.

[0021] Finally, the top of the surface layer 2 is provided with multiple anti-slip protrusions 5, which can significantly improve the anti-slip performance and safety of the artificial turf. Moreover, the anti-slip protrusions of this utility model are truncated cones with micro-holes 501 on the top. The micro-holes 501 are filled with anti-slip particles 502. In this way, the anti-slip protrusion 5 is a truncated cone-shaped protrusion structure. Compared with traditional flat or columnar protrusions, its inclined surface can disperse contact pressure, reduce protrusion wear, and extend service life. The micro-holes 501 on the top provide a fixed space for the anti-slip particles 502. When the anti-slip particles 502 are subjected to external friction, they can form multi-directional resistance, further enhancing the surface anti-slip effect. Especially in wet or muddy environments, the irregular surface of the particles can pierce the water film, increase contact friction, and effectively prevent slipping.
