Description

Technical Field

[0001] This invention relates to the field of compacted snow runway design technology, specifically a method for strengthening the wear resistance of compacted snow runway pavement in polar airports. Background Technology

[0002] Ice and snow runways can be divided into four types: sea ice runways, blue ice runways, toboggan runways, and compacted snow runways. Ice runway design is similar to rigid runway design, while snow runway design is similar to flexible runway design. Compacted snow runways are the optimal choice for my country to build runways suitable for heavy wheeled aircraft takeoffs and landings in Antarctica. In Antarctica, snow layers are mostly attached to ice. Compacted snow runways use snow accumulated on the ice as the base and surface construction material, artificially compacting the snow to increase its density, and then sintering to enhance its strength. The sintering process refers to the process of raising the density of snow particles. The process of snow crystal sublimation, condensation, recrystallization, volume diffusion, and the formation of a new cementitious body with surrounding particles, along with the increase in strength, is a crucial indicator for snow track design. Many factors influence snow strength, such as sintering, strain rate, temperature, particle size distribution, and density. Sintering refers to the process of snow crystal sublimation, condensation, and recrystallization. Snow crystals sublimate into water vapor, which migrates from warm to cold regions under the influence of a temperature gradient. During this migration, the water vapor condenses on the surface of the snow crystal and diffuses outwards, solidifying into ice and forming a cement with adjacent snow crystals.

[0003] Most existing compacted snow runways are double-layered. When an aircraft lands, its landing gear comes into contact with the top of the compacted snow runway, which causes a certain degree of wear. Furthermore, the aircraft landing gear directly contacts the elastic layer, which will cause excessive wear to the elastic layer over time. Therefore, we propose a wear-resistant reinforcement method for compacted snow runway surfaces in polar airports. Summary of the Invention

[0004] The purpose of this invention is to provide a method for strengthening the wear resistance of compacted snow runway surfaces in polar airports.

[0005] To address the problems mentioned in the background section, the present invention provides the following technical solution: a method for strengthening the wear resistance of compacted snow runway pavement in polar airports, wherein the specific steps of the method are as follows:

[0006] Step 1: When constructing a compacted snow track, it can be divided into a base layer, an elastic layer, and a smooth layer. During the construction of the base layer, mechanical equipment can be used to excavate the ice and snow. The excavated ice and snow are then put into a crusher for crushing. Half of the crushed ice and snow is then heated to turn it into liquid water, which is then distilled through a distiller. The distilled water is then filtered through activated carbon and a filter screen to reduce impurities. Finally, the purified water is placed in the pre-designed pit of the track and solidified into an ice layer by pressurization.

[0007] Step 2: Lay a layer of ice and snow on top of the ice layer and compact it with a compactor. Then pour pure water onto the ice surface. The ice layer formed after pouring water will increase the strength of the overall structure. Repeat the above operation until the pavement thickness reaches 50cm, thus completing the construction of the subgrade.

[0008] The third step is to take half of the remaining ice and snow after the construction of the base layer, mix it with wood chips and rubber granules, and then lay the mixed ice and snow on the base layer. At the same time, pour pure water onto the pavement and compact it with a compactor. After compaction, lay the ice and snow mixed with wood chips and rubber granules again, then pour pure water again and compact the pavement with a compactor. Repeat the above steps until the pavement thickness reaches 1m, thus completing the construction of the elastic layer.

[0009] The fourth step is to mix the remaining ice and carbon fiber and lay it on top of the elastic layer. Compact it thoroughly with a compactor, then add pure water and let it stand for 10 minutes until the pure water completely penetrates the surface. Lay the ice and carbon fiber mixture again and pour pure water. The ice layer formed after watering will increase the strength and wear resistance of the track, thus completing the construction of the smooth layer.

[0010] The fifth step is to maintain the flatness of the pavement when constructing the base layer, elastic layer, and smooth layer. During construction, a laser leveling instrument is used to measure the flatness, and the pavement is then ground with a grinding machine based on the measurement data to ensure the flatness of the pavement.

[0011] As a further aspect of the present invention: In step one, the excavated ice and snow are crushed into snow particles. As the particle size of the snow particles becomes smaller, the pores between them are reduced. When these snow particles are compressed, a denser structure is formed, thereby improving the compressive strength of the runway.

[0012] As a further aspect of the present invention: In step one, half of the crushed ice and snow is used for distillation. Impurities in the ice and snow are removed by distillation and filtration. Removing impurities makes the surface of the ice and snow smoother and reduces friction, thereby increasing the wear resistance of the pavement.

[0013] As a further aspect of the present invention: in steps two, three and four, pouring pure water onto the pavement can help the ice layer solidify and harden more quickly, and pouring pure water can make the ice and snow mixture bond together more tightly to form a solid ice layer.

[0014] As a further aspect of the present invention: in step three, the content of added wood chips and rubber particles is 5% and 2% of the total amount of ice and snow, respectively, thereby increasing the elasticity and toughness of the track by mixing rubber particles and wood chips with ice and snow.

[0015] As a further aspect of the present invention: In step four, by laying and compacting the mixture of ice and carbon fiber, and then pouring pure water, the resulting ice layer can increase the overall strength and wear resistance of the track, making it more durable and stable, and can ensure that the structure of the smooth layer is more robust and stable, reducing the possibility of cracks and deformation.

[0016] As a further aspect of the present invention: In step four, repeated watering can help the carbon fiber to better bond with the ice and snow mixture, increase the strength and wear resistance of the mixture, and the carbon fiber can increase the toughness of the ice and snow through its own properties, further enhancing the wear resistance of the track.

[0017] As a further aspect of the present invention: In step five, a laser leveling instrument is used in conjunction with a grinding machine to grind the top of each base layer so that its vertical height within a 5m range is no more than 0.5cm and its transverse and longitudinal slopes are no more than 1 to 2 degrees. At the same time, the top surface of the smoothing layer needs to be cleaned to maintain its surface smoothness.

[0018] Compared with the prior art, the beneficial effects of the present invention by adopting the above technical solution are as follows:

[0019] 1. This invention obtains purer water for pavement construction by excavating and processing ice and snow, including crushing, heating, distilling and filtering. This helps reduce impurities in the ice and snow, making the pavement surface smoother and more even, thereby reducing friction and increasing the pavement's wear resistance. Furthermore, by mixing wood chips and rubber granules with ice and snow and spreading them on the subgrade, this treatment method can increase the pavement's wear resistance and service life.

[0020] 2. This invention forms a smooth layer by mixing carbon fiber and ice and snow and spreading it flat. The use of pure water helps the ice layer to solidify and harden faster, and makes the ice and snow mixture and carbon fiber more tightly bonded together to form a strong ice layer, which helps to improve the overall strength and wear resistance of the pavement.

Furthermore, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0023] This invention discloses a method for strengthening the wear resistance of compacted snow runway surfaces in polar airports. The specific steps of the method are as follows:

[0024] Step 1: When constructing a compacted snow track, it can be divided into a base layer, an elastic layer, and a smooth layer. During the construction of the base layer, mechanical equipment can be used to excavate the ice and snow. The excavated ice and snow are then put into a crusher for crushing.

[0025] Step 2: Lay a layer of ice and snow on top of the ice layer and compact it with a compactor. Then pour pure water onto the ice surface. The ice layer formed after pouring water will increase the strength of the overall structure. Repeat the above operation until the pavement thickness reaches 50cm, thus completing the construction of the subgrade.

[0026] The third step is to take half of the remaining ice and snow after the construction of the base layer, mix it with wood chips and rubber granules, and then lay the mixed ice and snow on the base layer. At the same time, pour pure water onto the pavement and compact it with a compactor. After compaction, lay the ice and snow mixed with wood chips and rubber granules again, then pour pure water again and compact the pavement with a compactor. Repeat the above steps until the pavement thickness reaches 1m, thus completing the construction of the elastic layer.

[0027] The fourth step is to mix the remaining ice and carbon fiber and lay it on top of the elastic layer. Compact it thoroughly with a compactor, then add pure water and let it stand for 10 minutes until the pure water completely penetrates the surface. Lay the ice and carbon fiber mixture again and pour pure water. The ice layer formed after watering will increase the strength and wear resistance of the track, thus completing the construction of the smooth layer.

[0028] The fifth step is to maintain the flatness of the pavement when constructing the base layer, elastic layer, and smooth layer. During construction, a laser leveling instrument is used to measure the flatness, and the pavement is then ground with a grinding machine based on the measurement data to ensure the flatness of the pavement.

[0029] In one embodiment of the present invention: In step one, the excavated ice and snow are crushed into snow particles. As the particle size of the snow particles becomes smaller, the pores between them are reduced. When these snow particles are compressed, a denser structure is formed, thereby improving the compressive strength of the runway.

[0030] In one embodiment of the present invention: In step one, half of the crushed ice and snow is used for distillation. Impurities in the ice and snow are removed by distillation and filtration. Removing impurities makes the surface of the ice and snow smoother and reduces friction, thereby increasing the wear resistance of the pavement.

[0031] In one embodiment of the present invention: in steps two, three and four, pouring pure water onto the pavement can help the ice layer solidify and harden faster, and pouring pure water can make the ice and snow mixture bond together more tightly to form a solid ice layer.

[0032] In one embodiment of the present invention: in step three, the content of wood chips and rubber particles added is 5% and 2% of the total amount of ice and snow, respectively, and the elasticity and toughness of the track are increased by mixing rubber particles and wood chips with ice and snow.

[0033] In one embodiment of the present invention: In step four, by laying and compacting the mixture of ice and carbon fiber, and then pouring pure water, the resulting ice layer can increase the overall strength and wear resistance of the track, making it more durable and stable, and can ensure that the structure of the smooth layer is more robust and stable, reducing the possibility of cracks and deformation.

[0034] In one embodiment of the present invention: In step four, repeated watering can help the carbon fiber to better bond with the ice and snow mixture, increase the strength and wear resistance of the mixture, and the carbon fiber can increase the toughness of the ice and snow through its own properties, further enhancing the wear resistance of the track.

[0035] In one embodiment of the present invention: In step five, a laser leveling instrument is used in conjunction with a grinding machine to grind the top of each base layer so that the vertical height within a 5m range is no more than 0.5cm and the horizontal and vertical slopes are no more than 1 to 2 degrees. At the same time, the top surface of the smooth layer needs to be cleaned to maintain its surface smoothness.

[0036] Example 1, please refer to the appendix. Figure 1 .

[0037] This embodiment provides a method for strengthening the wear resistance of compacted snow runway surfaces in polar airports. The specific steps of the method are as follows:

[0038] Step 1: When constructing a compacted snow track, it can be divided into a base layer, an elastic layer, and a smooth layer. During the construction of the base layer, mechanical equipment can be used to excavate the ice and snow. The excavated ice and snow are then put into a crusher for crushing. Half of the crushed ice and snow is then heated to turn it into liquid water, which is then distilled through a distiller. The distilled water is then filtered through activated carbon and a filter screen to reduce impurities. Finally, the purified water is placed in the pre-designed pit of the track and solidified into an ice layer by pressurization.

[0039] Step 2: Lay a layer of ice and snow on top of the ice layer and compact it with a compactor. Then pour pure water onto the ice surface. The ice layer formed after pouring water will increase the strength of the overall structure. Repeat the above operation until the pavement thickness reaches 50cm, thus completing the construction of the subgrade.

[0040] The third step is to take half of the remaining ice and snow after the construction of the base layer, mix it with wood chips and rubber granules, and then lay the mixed ice and snow on the base layer. At the same time, pour pure water onto the pavement and compact it with a compactor. After compaction, lay the ice and snow mixed with wood chips and rubber granules again, then pour pure water again and compact the pavement with a compactor. Repeat the above steps until the pavement thickness reaches 1m, thus completing the construction of the elastic layer.

[0041] The fourth step is to mix the remaining ice and carbon fiber and lay it on top of the elastic layer. Compact it thoroughly with a compactor, then add pure water and let it stand for 10 minutes until the pure water completely penetrates the surface. Lay the ice and carbon fiber mixture again and pour pure water. The ice layer formed after watering will increase the strength and wear resistance of the track, thus completing the construction of the smooth layer.

[0042] The fifth step is to maintain the flatness of the pavement when constructing the base layer, elastic layer, and smooth layer. During construction, a laser leveling instrument is used to measure the flatness, and the pavement is then ground with a grinding machine based on the measurement data to ensure the flatness of the pavement.

[0043] The excavated ice and snow are crushed into snow particles. As the particle size of the snow particles decreases, the pores between them are reduced. When these snow particles are compressed, they form a denser structure, thereby improving the runway's compressive strength.

[0044] In step one, half of the crushed ice and snow is used for distillation and purification. Distillation and filtration remove impurities from the ice and snow, making the surface smoother and reducing friction, thus increasing the pavement's wear resistance. This meticulous distillation and filtration process successfully removes impurities and impurities from the ice and snow. This method not only makes the ice and snow surface smoother but also effectively reduces friction between the pavement and vehicle tires, significantly improving the pavement's wear resistance and service life. By removing impurities, the purity of the ice and snow is improved, making it more suitable for pavement construction and ensuring the quality and stability of the pavement. The introduction of this meticulous process provides higher-quality raw materials for pavement construction.

[0045] In steps two, three, and four, pouring purified water onto the pavement helps the ice layer solidify and harden more quickly. Furthermore, pouring purified water allows the ice and snow mixture to bind together more tightly, forming a solid ice layer, which indirectly enhances the pavement's wear resistance. These methods make the pavement more durable, effectively reduce maintenance costs, and extend its service life.

[0046] In step three, the added wood chips and rubber granules account for 5% and 2% of the total amount of ice and snow, respectively. By mixing the rubber granules and wood chips with the ice and snow, the elasticity and toughness of the track are increased, thereby improving the compressive strength and durability of the track surface. The addition of wood chips and rubber granules can not only improve the elasticity of the track surface and reduce excessive stress concentration when the track surface is subjected to force, but also effectively slow down the wear and aging rate of the track surface, giving the track surface better impact resistance and durability.

[0047] In step four, by laying and compacting the mixture of ice and carbon fiber and then pouring in pure water, the resulting ice layer can increase the overall strength and wear resistance of the track, making it more durable and stable. It can also ensure that the structure of the smooth layer is more robust and stable, reducing the possibility of cracks and deformation. First, the addition of carbon fiber can significantly enhance the overall strength and wear resistance of the track surface, making it more durable. The high strength and excellent durability of carbon fiber provide additional support for the track surface, extending its service life. Second, by mixing carbon fiber, the structure of the smooth layer can be ensured to be more robust and stable.

[0048] In step four, repeated watering helps the carbon fiber bond better with the ice and snow mixture, increasing the strength and abrasion resistance of the mixture. Furthermore, the carbon fiber, through its own properties, can increase the toughness of the ice and snow, further enhancing the abrasion resistance of the track. Repeated watering not only helps the carbon fiber bond better with the ice and snow mixture but also increases the overall strength and abrasion resistance of the mixture. Moreover, through repeated watering, the carbon fiber can be more evenly distributed throughout the entire track surface, ensuring its effectiveness and stability. At the same time, the addition of carbon fiber not only improves the overall strength and abrasion resistance of the track surface but also increases the toughness of the ice and snow through its own properties, further enhancing the abrasion resistance of the track.

[0049] In step five, a laser leveling instrument is used in conjunction with a grinder to grind the top of each base layer, ensuring that the vertical height within a 5m range is no more than 0.5cm and the transverse and longitudinal slopes are no more than 1-2 degrees. At the same time, the top surface of the smooth layer needs to be cleaned to maintain its smoothness. The precise grinding process can effectively improve the flatness and smoothness of the road surface, ensuring the comfort and safety of the road.
