Description

Technical Field

[0001] This utility model relates to the field of plastic running track technology, and in particular to a drainage type plastic running track. Background Technology

[0002] Plastic running tracks are widely used in various sports venues such as schools, stadiums, and fitness trails due to their advantages such as good elasticity, wear resistance, slip resistance, bright colors, and ease of maintenance.

[0003] In actual use, especially in rainy areas or during the rainy season, rainwater is difficult to drain after seeping into the track base layer, forming internal water accumulation and affecting the stability of the track structure. In addition, long-term dampness will accelerate the aging of adhesives and the shedding of particles, reducing the elasticity and service life of the track. Therefore, in order to address the above technical problems, it is necessary to design a drainage-type plastic track with a reasonable structure that does not affect the performance of the track, so as to effectively solve the problem of internal water accumulation and extend its service life. Utility Model Content

[0004] This invention proposes a drainage-type plastic running track, which solves the above-mentioned problems existing in the use of the prior art.

[0005] The technical solution of this utility model is implemented as follows: A drainage-type plastic running track includes a running track body and a ditch located on one side of the running track body. The running track body includes, from top to bottom, a rubber layer, a buffer layer, a drainage layer, and a leveling layer. The leveling layer is connected to one side of the ditch. The ditch has a drainage channel. The drainage layer has a drainage system that leads into the drainage channel. The drainage system includes several drainage pipes. The drainage pipes extend from the side away from the ditch toward the ditch. The ditch has drainage outlets for inserting drainage pipes and communicating with the drainage channel. Each drainage pipe has upwardly extending water inlet branch pipes evenly distributed. The upper end of each water inlet branch pipe has a water inlet. The drainage pipes are buried in the drainage layer. The upper surface of the drainage layer has a grid-like water channel that connects to each water inlet.

[0006] Preferably, the upper end of the water inlet branch pipe is provided with a top plate, and a support rod is fixedly connected between the top plate and the upper end of the water inlet branch pipe. The support rod is used to separate the water inlet branch pipe from the top plate so that the water inlet is exposed. The top plate is flush with the upper surface of the drainage layer.

[0007] Preferably, the mesh-like water tank is covered with a seepage plate.

[0008] Preferably, the mesh-like water tank has a stepped groove at its opening, and the seepage plate is installed in the stepped groove.

[0009] Preferably, the drain pipe is inclined downwards from the side away from the ditch.

[0010] Preferably, the cross-section of the drainage ditch is in the shape of an inverted isosceles trapezoid, and several reinforcing rods are horizontally fixedly installed on the upper side of the ditch.

[0011] Preferably, the ditch is covered by a drainage ditch cover plate, and the upper surface of the rubber layer, the upper surface of the drainage ditch, and the upper surface of the drainage ditch cover plate are on the same plane.

[0012] Preferably, the ditch and the leveling layer have a layer of crushed stone underneath.

[0013] In summary, the beneficial effects of this utility model are as follows: 1. This application provides a structurally sound and highly efficient drainage-type synthetic running track. By incorporating a multi-layered structure beneath the track body—comprising a rubber layer, a buffer layer, a drainage layer, and a leveling layer—and a ditch connected to the drainage layer on one side of the track, rapid and directional drainage of rainwater after it has permeated from the surface into the interior is achieved. Specifically, the drainage layer contains radially distributed drainage pipes extending at an incline into the ditch, which, along with equally spaced inlet branches and a top inlet, allows rainwater to efficiently flow into the drainage system through a grid-like channel, ultimately draining into the drainage ditch within the ditch. This structure significantly improves the drainage efficiency of the track's interior, preventing material aging and structural damage caused by long-term water accumulation, effectively extending the service life of the synthetic running track. It is particularly suitable for rainy areas or sports venues with high drainage requirements.

[0014] 2. Install a top plate at the upper end of the water inlet branch pipe, and separate the top plate from the water inlet branch pipe with support rods to keep the water inlet unobstructed and exposed. The top plate can effectively prevent large particles of debris and upper layer materials from falling directly into the water inlet and causing blockage. Covering the grid-shaped water trough with a seepage board can prevent rainwater from falling in during the laying of upper layer materials without affecting the entry of rainwater, thus preventing blockage of the drainage path.

[0018] The following will refer to the appendix in the embodiments of this utility model. Figure 1-6 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] Example: like Figures 1 to 6 As shown, this utility model discloses a drainage-type plastic running track, aiming to solve the problems of internal water accumulation, material aging, and structural damage caused by the inability to drain rainwater in time after infiltration in some existing plastic running tracks. This drainage-type plastic running track achieves the technical effect of rapid rainwater infiltration from the surface and efficient drainage to the side ditches through a multi-layered structural design and the synergistic effect of a built-in directional drainage system.

[0020] This drainage-type plastic running track includes a running track body and a ditch 1 located on one side of the running track body. The running track body, from top to bottom, includes a rubber layer 2, a buffer layer 3, a drainage layer 4, and a leveling layer 5. The rubber layer 2 is the uppermost layer of the running track and is made of a mixture of various elastic materials such as polyurethane prepolymer, mixed polyether, waste tire rubber granules, EPDM rubber granules, or PU granules. During the curing process, this mixture forms numerous micropores, creating a breathable and water-permeable structure, allowing rainwater to quickly permeate downwards from the top surface of the rubber layer 2 through these micropores into the buffer layer 3. The buffer layer 3, located below the rubber layer 2, is mainly composed of rubber granules and polyurethane adhesive mixed in a certain proportion, spread, and compacted, providing good elasticity and cushioning performance. This layer not only serves to absorb shock and prevent slippage but also acts as a transition layer, allowing moisture to continue permeating downwards to the drainage layer 4 while preventing the upper material particles from sinking and affecting structural stability. Furthermore, to further improve the permeability of the buffer layer 3, several drainage holes 31 leading to a grid-like water channel 41 can be formed on the buffer layer 3.

[0021] The leveling layer 5 is connected to one side of the ditch 1. A drainage ditch 11 is located within the ditch 1. The ditch 1, drainage layer 4, and leveling layer 5 are all cast in concrete. The leveling layer 5 is used to adjust the flatness of the foundation, ensuring uniform stress on the upper structural layers. The drainage layer 4, located above the leveling layer 5, is one of the core structures for drainage. The drainage layer 4 contains a drainage system that leads into the drainage ditch 11. This drainage system includes several drainage pipes 71 arranged along the width of the runway. The drainage pipes 71 extend from the side away from the ditch 1 towards the ditch 1 and are inclined downwards, preferably at an angle of 1% to 3%, to facilitate natural flow of rainwater by gravity, achieving smooth drainage without external power. The end of the drainage pipe 71 away from the ditch 1 is sealed. A drainage outlet 12 is provided on the ditch 1, through which a water supply and drainage pipe 71 is inserted and connected to the drainage ditch 11. Multiple vertically extending branch pipes 72 are evenly distributed on each drainage pipe 71. Each branch pipe 72 has an inlet 73 at its top for receiving seepage water from above. To prevent the inlet 73 from being blocked by debris, a top plate 74 is installed at the top of the branch pipe 72. The top plate 74 is fixedly connected to the top of the branch pipe 72 by several support rods 75 arranged in a circular pattern, creating a gap between the top plate 74 and the branch pipe 72. This ensures that the inlet 73 is always exposed, allowing water to flow in while preventing large particles of debris and residue from the upper layer of material from falling directly into the inlet 73 and causing blockage. The upper surface of the top plate 74 is flush with the upper surface of the drainage layer 4 to avoid stress concentration or construction inconvenience caused by height differences. A grid-like water channel 41 is formed on the upper surface of the drainage layer 4. This channel, arranged in a crisscrossing grid pattern, connects to each inlet 73, collecting rainwater infiltrating from the buffer layer 3 and guiding it to the inlets 73 of each branch pipe 72. To prevent the upper material from falling into and clogging the drainage path during installation, a permeable plate 8 is placed above the openings of the grid-like water channel 41. The permeable plate 8 is made of high-strength plastic or composite material and has evenly distributed permeable holes. Alternatively, after the buffer layer 3 is installed, a perforating tool can be used to penetrate the permeable plate 8 downwards through the drainage holes 31 in the buffer layer 3 that lead to the grid-like water channel 41, forming through holes 81 corresponding to the drainage holes 31, thereby improving its permeability.

[0022] The installation structure of the seepage plate 8 adopts a positioning method using stepped grooves 42. Specifically, stepped grooves 42 are pre-cut at the opening edge of the grid-like water tank 41, and the seepage plate 8 is embedded into these grooves for fixation.

[0023] The cross-section of the drainage ditch 11 is in the shape of an inverted isosceles trapezoid, and several reinforcing rods 13 are horizontally fixedly installed on the upper side of the drainage ditch 11. The above structure enhances the structural strength and overall load-bearing capacity of the ditch.

[0024] The ditch 1 is covered by a drainage ditch cover 14. The upper surfaces of the rubber layer 2, the drainage ditch 11, and the drainage ditch cover 14 are all on the same plane. This ensures that the surface of the entire running track area is flat and continuous, without sudden changes in elevation, avoiding safety accidents such as tripping during running, and improving the safety and comfort of use.

[0025] In addition, a gravel layer 6 is provided at the bottom of the ditch 1 and below the leveling layer 5. This gravel layer 6 is made of clean gravel with a particle size of 20-40mm and a thickness of about 150-300mm, and has good permeability and filtration function.

[0026] During construction, the foundation is first leveled and compacted, and a layer of crushed stone 6 is laid and compacted. Then, the leveling layer and drainage layer concrete are poured in sequence. When pouring the drainage layer 4, drainage pipes 71 are pre-embedded, and grid-shaped water channels 41 and stepped grooves 42 are opened simultaneously. After the concrete has cured, the permeable board 8 is covered, and the buffer layer 3 and rubber layer 2 are laid. When laying the buffer layer 3, drainage holes 31 are left, and after the buffer layer 3 is laid, through holes 81 are opened on the permeable board 8 through the drainage holes 31. In addition, while pouring the leveling layer and drainage layer concrete, a ditch 1 structure is built on the side, and the end of the drainage pipe 71 is connected to the drainage ditch 11. The drainage ditch cover 14 is installed to complete the overall construction.
