Description

Technical Field

[0001] The utility model belongs to the technical field of runways, and more specifically, relates to a side-permeable prefabricated runway. Background Art

[0002] A prefabricated runway typically refers to a runway constructed using prefabricated components. These can be prefabricated in a factory and require only on-site assembly. Due to their fast construction speed and minimal environmental impact, they have been widely used in various fields. To further ensure the runway's anti-slip properties and safety, track rolls are often laid on the runway. This improves the runway's overall performance, increases friction, and provides a certain degree of elasticity and cushioning. However, the track rolls used in traditional prefabricated runways are typically rubber rolls. These rolls are manufactured using a variety of processes and have a tight, airtight structure. Furthermore, during the laying process, they are affected by surface moisture and thermal expansion and contraction, making it difficult for surface moisture to dissipate. This moisture accumulates within the runway, which can easily lead to undesirable phenomena such as bubbling, aging, cracking, and delamination. These problems not only affect the runway's flatness but also severely damage its integrity and stability, causing it to lose its original elasticity and protective properties, shortening its service life. Utility Model Content

[0003] In order to solve the above technical problems, the present invention provides a side-permeable prefabricated runway to solve the technical problem in the prior art that the runway roll material used for paving traditional prefabricated runways is usually a rubber roll material with a tight and airtight structure, which causes the accumulation of water vapor inside for a long time, easily leading to various adverse phenomena on the runway, thereby destroying the integrity and stability of the runway and reducing its service life.

[0004] The purpose and function of the side-permeable prefabricated runway of the present invention are achieved by the following specific technical means:

[0005] A side-permeable prefabricated runway comprises a concrete layer, a runway base layer is arranged below the concrete layer, a moisture-proof layer is arranged between the runway base layer and the concrete layer, and two sides of the moisture-proof layer are in contact with the runway base layer and the concrete layer respectively; a runway roll is arranged above the concrete layer, the runway roll comprises an anti-slip layer and a breathable layer, and the breathable layer is connected to the concrete layer.

[0006] According to a preferred embodiment, the runway bottom layer includes a cement stone powder layer and a plain stone compaction layer, one side of the cement stone powder layer is in contact with the moisture-proof layer, and a crushed stone cushion layer is further provided between the cement stone powder layer and the plain stone compaction layer.

[0007] According to a preferred embodiment, the breathable layer is formed by pressing 1-3MM polyurethane particles, and the thickness of the breathable layer is 9-10 mm.

[0008] According to a preferred embodiment, a reinforcing layer is provided between the anti-slip layer and the breathable layer. The thickness of the reinforcing layer and the anti-slip layer are both 2 mm. The runway roll material with a thickness of 13 mm is formed by the breathable layer, the reinforcing layer and the anti-slip layer.

[0009] According to a preferred embodiment, the reinforcement layer and the anti-slip layer are both coated on the breathable layer by a scraping method and are embossed.

[0010] According to a preferred embodiment, an adhesive is provided between the air-permeable layer and the concrete layer. The adhesive is provided in a strip shape, and the air-permeable layer is connected to the concrete layer via the adhesive.

[0011] According to a preferred embodiment, a sealing primer is rolled on the top surface of the concrete layer.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. The runway membrane consists of an anti-slip layer and a breathable layer. The breathable layer is pressed from 1-3MM polyurethane particles. Due to the irregular multi-faceted nature of the particles, it has good breathability. When surface water vapor is released onto the breathable layer, the breathable layer uses side permeation to expand and contract and exhaust. There are a large number of irregular gaps in the breathable layer that can accept the discharge of gas, and then the gas is exhausted by side permeation, avoiding quality problems such as bubbling or even delamination of the membrane due to the inability to discharge surface gas, thereby avoiding damage to the integrity and stability of the runway and increasing the service life of the runway.

[0014] 2. A sealing primer is rolled onto the top surface of the concrete layer. This sealant acts as a barrier to some moisture, effectively reducing the amount of moisture that enters the concrete, thereby mitigating its potential threat to the structural stability. Simultaneously, the breathable layer is connected to the concrete layer with adhesive in strips, rather than the traditional full-coverage method. This ensures a secure connection while leaving ample channels for moisture to escape, allowing surface moisture to escape smoothly into the breathable layer within the runway membrane.

[0021] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following embodiments are used to illustrate the technical solution of the present invention, but are not intended to limit the scope of protection of the present invention.

[0022] Example:

[0023] like Figures 1 to 4 As shown, the present invention provides a side-permeable prefabricated runway, comprising a concrete layer 11, a runway sub-layer 21 disposed below the concrete layer 11, and a moisture-proof layer 12 disposed between the runway sub-layer 21 and the concrete layer 11. The moisture-proof layer 12 contacts the runway sub-layer 21 and the concrete layer 11 on both sides, effectively preventing the rise of underground moisture and water. A runway coil 31 is disposed above the concrete layer 11. The runway coil 31 includes an anti-slip layer 32 and a breathable layer 33. When moisture is generated on the surface, it quickly permeates the breathable layer 33. The anti-slip layer 32 provides the necessary friction for athletes, ensuring a stable footing when running, sprinting, or turning, reducing the risk of slipping. The breathable layer 33 is directly connected to the concrete layer 11, ensuring that moisture can be smoothly transferred between the two, further optimizing the runway's ventilation. The entire runway coil 31 not only enhances the user experience of the runway, but also extends its service life and reduces maintenance costs.

[0024] like Figure 2 、 4 As shown, the runway sub-base 21 includes a cement powder layer 22 and a compacted stone layer 23. One side of the cement powder layer 22 is in contact with the moisture-proof layer 12, effectively absorbing and evenly distributing the pressure transmitted from above. The cement powder layer 22 has a certain strength and stability, providing support for the runway. A crushed stone cushion layer 24 is also provided between the cement powder layer 22 and the compacted stone layer 23. The crushed stone cushion layer 24 has a structure with excellent load-bearing capacity and cushioning properties. When the runway is impacted by athletes' footsteps, the crushed stone cushion layer 24 can absorb and disperse some of the energy, reducing the pressure on the upper structure and thus extending the runway's service life.

[0025] like Figure 2 、 3As shown, the breathable layer 33 is formed by compressing 1-3 mm polyurethane pellets. The irregular size and shape of the polyurethane pellets create a multifaceted structure, resulting in excellent breathability. Simultaneously, the breathable layer 33 is 9-10 mm thick, ensuring sufficient air permeability to allow surface moisture to escape smoothly while also providing a certain degree of elasticity and cushioning, reducing the impact forces on the athletes' feet. A reinforcing layer 34 is positioned between the anti-slip layer 32 and the breathable layer 33. Both the reinforcing layer 34 and the anti-slip layer 32 are 2 mm thick. Together, the breathable layer 33, the reinforcing layer 34, and the anti-slip layer 32 form a 13 mm thick runway coil 31. The presence of the reinforcing layer 34 significantly enhances the overall strength and tensile strength of the runway coil 31, effectively preventing deformation and cracking during long-term use. The anti-slip layer 32 provides a crucial safeguard for athlete safety. Its 2 mm thickness can provide sufficient friction without affecting the overall performance of the runway, allowing athletes to control their pace stably while running.

[0026] The reinforcing layer 34 and the anti-slip layer 32 are both applied to the breathable layer 33 by scraping, and then embossed. This ensures that the reinforcing layer 34, the anti-slip layer 32, and the breathable layer 33 are in close contact with each other, without gaps or delamination, thus forming an integral structure. The embossing treatment performed after the scraping is completed improves the anti-slip performance. When athletes make sharp turns or sudden accelerations, the additional friction brought by the embossing treatment allows them to more stably control their body balance and reduce the risk of accidental slips. An adhesive 13 is provided between the breathable layer 33 and the concrete layer 11. The adhesive 13 is arranged in strips. Unlike traditional fully coated adhesives, the strip distribution ensures the connection between the breathable layer 33 and the concrete layer 11 while also leaving ample channels for the discharge of water vapor. Even in humid environments or when a lot of water vapor is generated on the surface due to a lot of exercise, the water vapor can be discharged smoothly through these channels, avoiding the adverse effects of water vapor accumulation on the performance of the runway. The breathable layer 33 is connected to the concrete layer 11 via adhesive 13, ensuring a secure bond between the two layers. A sealing primer 14 is roll-coated on the top surface of the concrete layer 11. This effectively seals the tiny pores within the concrete layer 11, reducing the penetration of moisture and impurities, thereby enhancing the durability and stability of the concrete layer 11. For example, over long-term use, the sealing primer 14 prevents liquids such as rainwater and sewage from invading the concrete layer 11, preventing problems such as loosening and cracking caused by erosion, thereby extending the runway's service life.

[0027] The basic principles, main features and advantages of the present invention are shown and described above. It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments.
