Description

Technical Field

[0001] This utility model relates to the field of runway technology, and in particular to a permeable runway. Background Technology

[0002] A runway is a dedicated road or field designed for running, flying, or other modes of transportation (such as airplanes, trains, etc.). It is commonly used for sports, aviation, rail, or other transportation activities. Runway design takes into account factors such as load-bearing capacity, flatness, and safety.

[0003] The existing running tracks have poor water permeability and drainage. When the track's permeability is poor, rainwater cannot infiltrate or drain in time, leading to water accumulation on the track surface. This not only affects the safety of the track, but also increases the risk of slips and falls, especially during sports competitions or training. For air or rail runways, water accumulation can increase the difficulty of controlling vehicles, delaying flights or train operations. If the track surface is not drained properly, slippery conditions are more likely to occur. For athletes, this not only increases the risk of injury, but may also affect competition performance and training effectiveness. A slippery track surface may also cause athletes to lose their footing, increasing the likelihood of sprains or falls. Utility Model Content

[0026] Example:

[0027] like Figure 1-3 As shown, a permeable running track includes a main track body 1 and a hydrophobic structural layer 2 disposed thereon. The hydrophobic structural layer 2 comprises, from bottom to top:

[0028] The root protection layer 26 is composed of a grass-planted concrete base, and a slow-release root-preventing agent is pre-embedded in its pores;

[0029] The geothermal regulation layer 24 is composed of phase change material composite ceramic particles;

[0030] Microbial protective layer 23 is a silver-loaded zeolite particle filter layer;

[0031] Dynamic buffer layer 22, an elastomer layer with negative Poisson bit properties;

[0032] Fractal water-conducting layer 21 is a three-dimensional pipe network layer with a tree-like branching structure;

[0033] Superhydrophobic wear-resistant layer 25, modified polymer surface layer with a surface contact angle greater than 150°;

[0034] Among them, the branching angle of the fractal water-conducting layer 21 is 55°-65°, and the elastic modulus of the dynamic buffer layer 22 is dynamically matched with the drainage rate of the fractal water-conducting layer to form a cooperative drainage structure.

[0035] Root protection layer 26, material: grass concrete (cement: aggregate = 1:4, porosity 30%), root prevention treatment: 2mm particle size, 3-year release cycle of naphthyl benzoate slow-release particles are pre-embedded in the pores, function: inhibit deep-rooted plants from penetrating, while allowing shallow-rooted herbaceous plants to stabilize the soil.

[0036] Geothermal regulation layer 24, composition: expanded clay (particle size 12mm) coated with microcapsule paraffin wax (core material is triacontanane, phase change temperature 28℃), ratio: paraffin wax content 18% (mass fraction), expanded clay bulk density 650kg / m³, function: absorb heat in summer to reduce surface temperature by 5-8℃, release heat in winter to prevent frost heave.

[0037] Microbial protective layer 23, structure: silver-loaded zeolite particles (particle size 1.2 mm, Ag content 0.8%) filling layer (thickness 50 mm), preparation: loaded by silver nitrate solution ion exchange method, zeolite specific surface area reaches 450 m² / g, effect: continuous release of silver ions, sterilization rate >99%, service life up to 10 years.

[0038] The dynamic buffer layer 22 is made of thermoplastic polyurethane elastomer. The dynamic buffer layer 22 is made of thermoplastic polyurethane (TPU, Shore hardness 75A), has a structure of concave hexagonal honeycomb array (unit size 5cm×5cm×3cm, wall thickness 2mm), and has the following properties: it still maintains negative Poisson's ratio characteristics when compressed by 30%, and its elastic modulus dynamically matches the drainage rate.

[0039] Fractal water-conducting layer 21, design: four-level tree-like branch network (main branch pipe diameter ratio 1:0.618, branch angle 60°), parameters: main pipe diameter 80mm, end branch pipe diameter 15mm, slope 0.5%, drainage capacity: maximum drainage rate 120L / (m²·min), which is 3 times that of traditional design.

Characteristics: contact angle 158°, roll-off angle <5°, wear resistance up to 8000 cycles (Taber test).

[0041] Drainage-buffering coupling: When rainfall increases suddenly, the drainage rate of the fractal water-conducting layer 21 increases, triggering the reduction of the elastic modulus of the dynamic buffer layer 22 (through honeycomb structure deformation), expanding the cross-sectional area of ​​the drainage channel by 15%-20%. Temperature control-antibacterial linkage: The ground temperature regulating layer 24 stabilizes the temperature in the range of 25-35℃, avoiding the uncontrolled release of silver ions due to high temperature, while maintaining the zeolite ion exchange activity at low temperature.
