Abstract
Description
Technical Field
[0001] This application relates to the field of airport facilities, and in particular to an airport floor structure. Background Technology
[0002] Airport pavement, as a key area for passenger waiting, is a crucial component of airports. Its structural design and construction quality directly affect airport operational efficiency and passenger travel experience. Therefore, the design, construction, and maintenance of airport pavement structures must strictly adhere to relevant standards and specifications. Furthermore, airport pavement needs to withstand the weight of passengers and the pressure generated by luggage handling, while also providing excellent anti-slip properties in rainy or damp environments. With increasing environmental awareness, the environmental friendliness and sustainability of airport pavement are receiving growing attention.
[0003] Existing airport flooring typically consists of a flat layer laid on top of a subgrade, with concrete used to fill the gaps. However, in rainy weather, the water accumulation on the floor surface reduces the friction of the flat layer, affecting passenger safety and requiring regular manual cleaning. Meanwhile, the subgrade is permeated by moisture from the soil, gradually eroding the flat layer and hindering its sustainable use. Utility Model Content
[0004] To address the issues of water accumulation on airport floor surfaces affecting passenger safety and the susceptibility of the surface layer to erosion, which hinders its sustainable use, this application provides an airport floor structure.
[0005] The airport floor structure provided in this application adopts the following technical solution:
[0006] An airport floor structure includes a soil base layer, a support layer for bearing weight is provided on top of the soil base layer, a cushion layer for buffering and shock absorption is provided on top of the support layer, and a flat layer is provided on top of the cushion layer.
[0007] The top of the soil base layer is provided with mortar layers on both sides of the support layer for moisture isolation. A surface layer is provided on top of the mortar layer. Multiple left groove plates are provided on top of the surface layer. A right groove plate is provided on one side of each of the multiple left groove plates. A fixing layer is fixed between two adjacent right groove plates at the penetration opening of the soil base layer. An insert strip for joint sealing is provided between the two mortar layers in the support layer.
[0008] By adopting the above technical solution, the left and right channel plates are connected through the surface layer and the soil base layer, thereby guiding and draining the water accumulated on the surface layer. At the same time, the mortar layer blocks the moisture on both sides of the support layer. Combined with the multi-layer isolation structure connecting the soil base layer and the support layer, the planar layer is isolated in multiple directions to prevent water penetration and erosion.
[0009] Preferably, the bottoms of the multiple left groove plates and the adjacent right groove plates sequentially penetrate the surface layer, mortar layer and soil base layer to form a drainage channel.
[0010] By adopting the above technical solution, the left and right trough plates are connected to form a drainage channel, thereby diverting the horizontal flow of the surface layer. This allows the horizontal flow to enter the internal drainage facilities through the drainage channel, preventing water accumulation on the surface layer from affecting passenger walking safety.
[0011] Preferably, a soil layer is filled at the bottom of the soil base, and a drainage cavity is provided in the soil layer at the location of the soil base drainage channel.
[0012] By adopting the above technical solution, the drainage cavity opened in the soil layer provides storage space for the introduction of water and facilitates subsequent drainage processes.
[0013] Preferably, a limiting groove is formed at the bottom of the drainage chamber in the soil layer, and the limiting groove penetrates the soil layer to connect with the external drainage facilities.
[0014] By adopting the above technical solution, the limiting groove is connected to the external drainage facility, thereby reserving the activity space for the drainage process of the subsequent drain valve and ensuring the removal of water.
[0015] Preferably, a drain valve is movably disposed within the limiting groove, and a limiting ring is disposed around the top of the outer surface of the drain valve, with the outer surface of the limiting ring abutting against the channel of the limiting groove.
[0016] By adopting the above technical solution, the limiting ring abuts against the limiting groove, thereby limiting the drain valve within the limiting groove and preventing the drain valve from sliding out excessively.
[0017] Preferably, the bottom of the outer surface of the drain valve is provided with multiple drain ports, and the middle of the inner surface of the drain valve is fixed with a movable and extendable telescopic sleeve, the top of which is fixed to the bottom of the fixed layer.
[0018] By adopting the above technical solution, the telescopic sleeve connects the drain valve and the fixed layer, thereby driving the drain valve to move up and down so that the drain valve moves out of the limiting groove, thereby performing the drainage process.
[0019] Preferably, the top of the surface layer is provided with fixing grooves at the positions of multiple left and right groove plates, and the multiple left and right groove plates are fitted and fixedly connected to the fixing grooves.
[0020] By adopting the above technical solution, the fixed groove and the top folds of the left and right groove plates are fitted together, thereby maintaining the neatness of the top of the surface layer, while increasing the fixed area of the left and right groove plates and the surface layer.
[0021] Preferably, an expansion bolt is fixed to the top of the insert, and the expansion bolt passes through the bottom of the insert and is threadedly connected to the soil base.
[0022] By adopting the above technical solution, the bottom of the expansion bolt is extended within the soil base layer, thereby fixing the insert strip within the soil base layer and providing stability.
[0023] In summary, this application includes at least one of the following beneficial technical effects:
[0024] 1. The drainage channel formed by the left and right trough plates is connected to the drainage chamber, thereby guiding and discharging the water accumulated on the surface layer. The water is stored in the drainage chamber and exerts gravity on the drainage valve. The drainage valve slides down and discharges the water to the outside through multiple drainage outlets, thereby avoiding the safety impact of water remaining on the surface layer on passengers' walking.
[0025] 2. The soil base layer initially traps moisture, followed by a concrete support layer that further blocks moisture. Two mortar layers then cover the surface layer from both sides, thus protecting the surface layer and ensuring it has sufficient support while preventing erosion and damage from moisture in the soil, facilitating continuous use.

[0032] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.
[0033] This application discloses an airport floor structure.
[0034] Example 1
[0035] Reference Figure 1 , Figure 3 An airport floor structure includes a subgrade 1, which is made of cement and gravel mixed with water. The lower surface of the subgrade 1 is covered with a soil layer 7 to connect with the ground. The upper surface of the subgrade 1 is covered with a support layer 4, which is made of 66mm thick C30 concrete and contains steel fiber material to provide good load-bearing capacity. The upper surface of the support layer 4 is covered with a cushion layer 5, which is made of 2mm thick polyurethane flexible adhesive to evenly transfer the load on the top to the support layer 4, thereby buffering and dispersing vibration, and isolating moisture and water that permeates into the subgrade 1. The upper surface of the cushion layer 5 is covered with a flat layer 6, which is made of 12mm thick epoxy terrazzo, which has high strength and excellent wear resistance for long-term use. The flat layer 6 is located on the surface of the structure and its surface is set as a neat flat surface.
[0036] The subgrade 1 uses a mixture of cement and gravel to initially isolate water seeping into the soil. The support layer 4 is laid on top of the subgrade 1, using concrete to maintain support and compact the subgrade 1, thereby improving its compactness and waterproofing. The support layer 4 itself is also waterproof. This combination isolates water seeping into the soil below and protects the planar layer 6. Meanwhile, a flexible pad 5 is laid between the planar layer 6 and the support layer 4. When the planar layer 6 bears the weight and transmits it downwards, the pad 5 acts as a buffer and distributes the weight to the surface of the support layer 4, thus improving the service life of the support layer 4.
[0037] Reference Figure 2 , Figure 4 , Figure 5 On both sides of the support layer 4, the upper surface of the soil base 1 is covered with mortar layer 2. The mortar layer 2 is composed of 40mm thick dry cement mortar, and the ratio of cement to mortar is set at about 1:3. The upper surface of the mortar layer 2 is covered with surface layer 3, which is made of polished granite. During the polishing process of the granite, its surface is protected with oil on all six sides. When laying the surface layer 3, an adhesive is applied to its surface. At the same time, an L-shaped insert 17 is clamped and fixed between the mortar layer 2 and the support layer 4. The insert 17 is made of 3mm thick aluminum alloy, and the upper surface of the insert 17 is flush with the surface of the surface layer 3 to prevent moisture erosion and to separate the mortar layer 2 and the support layer 4. Multiple expansion bolts 18 are fixed at the L-shaped protrusion at the bottom of the insert 17. The bottom of the multiple expansion bolts 18 penetrates the insert 17 and is thus fixed to the soil base 1.
[0038] The smooth surface of the surface layer 3 is located at the top of the structure, thereby improving the overall aesthetics of the floor. At the same time, the mortar layer 2 fixes both sides of the support layer 4. The cement mortar structure of the mortar layer 2 also isolates moisture. Furthermore, the insert strip 17 set between the mortar layer 2 and the support layer 4 provides secondary isolation for the plane layer 6, thereby ensuring the moisture isolation effect on both sides of the plane layer 6. The bottom of the expansion bolt 18 is located in the soil base 1 and expands to improve the fixing effect, thereby fixing the insert strip 17 between the mortar layer 2 and the support layer 4.
[0039] Reference Figure 4 , Figure 5 The surface layer 3 has multiple fixing grooves 8 facing inward on its upper end. I-shaped left groove plates 9 and right groove plates 10 are fixed in pairs in each of the fixing grooves 8. The left groove plates 9 and right groove plates 10 are made of stainless steel and are corrosion resistant. The tops of the left groove plates 9 and right groove plates 10 are fitted and fixed to the fixing grooves 8. The bottoms of the left groove plates 9 and right groove plates 10 pass through the surface layer 3, mortar layer 2 and soil base layer 1 in sequence and are located in the soil layer 7. A drainage cavity 11 is provided at the penetration opening of the left groove plates 9 and right groove plates 10 in the soil layer 7. The inner surface of the drainage cavity 11 is coated with epoxy resin adhesive, which has good waterproof and adhesion properties and keeps the drainage cavity 11 stable. The penetration opening between the left groove plates 9 and right groove plates 10 forms a drainage channel and is connected to the drainage cavity 11. The bottom parts of the left groove plates 9 and right groove plates 10 located in the drainage cavity 11 are hook-shaped and a fixing layer 19 is fixed between the hook shape and the soil base layer 1.
[0040] It should be noted that the bottom of the drainage chamber 11 penetrates the bottom of the soil layer 7 and connects to the external drainage facilities. A limiting groove 12 is opened on the inner wall of the penetration. A limiting ring 15 is movable and abuts within the limiting groove 12. A drainage valve 13 is fixed in the middle of the limiting ring 15. The drainage valve 13 is cylindrical and hollow inside. Multiple drainage ports 14 that connect to the hollow are opened around the outer surface of the drainage valve 13. A telescopic sleeve 16 is fixed in the hollow center of the drainage valve 13. The top of the telescopic sleeve 16 is fixed to the fixed layer 19, and an elastic torsion spring is provided inside the telescopic sleeve 16 to maintain the rebound of the telescopic sleeve 16.
[0041] The through-holes of the left groove plate 9 and the right groove plate 10 connect the surface layer 3 and the drainage cavity 11, thereby guiding the accumulated water on the surface layer 3 and the plane layer 6, and introducing the accumulated water into the drainage cavity 11 through the drainage channel. At the same time, the left groove plate 9 and the right groove plate 10 respectively abut and support the inner wall of the through-hole to prevent the structure of the soil base layer 1 from loosening. The accumulated water enters the drainage cavity 11 for storage, and then flows into the hollow of the drainage valve 13, thereby applying gravity to the drainage valve 13. The drainage valve 13 moves downward under the gravity, causing the limiting ring 15 to move within the limiting groove 12. When the bottom of the drainage valve 13 protrudes from the soil layer 7, the accumulated water flows out through multiple drainage ports 14 to the external drainage facilities (such as sewers). The discharge of the accumulated water cancels the application of gravity to the drainage valve 13, and the torsion spring in the telescopic sleeve 16 rebounds, thereby retracting the drainage valve 13 to a state where the bottom is flush with the lower end face of the soil layer 7.
[0042] The implementation principle of an airport pavement structure according to an embodiment of this application is as follows: When using this structure, a drainage cavity 11 is opened on the surface of the soil layer 7, and epoxy resin glue is applied to the inner wall of the drainage cavity 11 to maintain the stability of the drainage cavity 11. Then, a left groove plate 9 and a right groove plate 10 are placed on the top of the drainage cavity 11, and the left groove plate 9 and the right groove plate 10 are in a relative state. A fixing layer 19 is fixed at the bottom of the left groove plate 9 and the right groove plate 10, and a drainage structure such as a telescopic sleeve 16 and a drainage valve 13 is fixed at the bottom of the fixing layer 19. Then, the soil base 1 is poured from the side surfaces of the left groove plate 9 and the right groove plate 10. A support layer 4, a cushion layer 5 and a flat layer 6 are poured in sequence in the middle of the upper end surface of the soil base 1. A mortar layer 2 and a surface layer 3 are poured in sequence on both sides of the upper end surface of the soil base 1. An insert strip 17 is set between the mortar layer 2 and the support layer 4 by an expansion bolt 18, thereby completing the laying of the structure.
[0043] When water accumulates on the surface layer 3 and the planar layer 6 of the rainy angel, the drainage channels at the top of the left channel plate 9 and the right channel plate 10 guide the water in. The water flows into the channel and into the drainage chamber 11. As the water flows in, it gradually applies downward pressure to the drainage valve 13. The drainage valve 13 is pressured and slides down along the limiting groove 12, so that the water flows from the drainage outlet 14 into the external drainage facility, thereby completing the drainage of the water and preventing water accumulation on the surface layer 3 and the planar layer 6, which could cause slippage for passengers.
[0044] Simultaneously, during the use of the floor structure, the support layer 4 compresses the soil base 1, thereby improving the waterproofing of the soil base 1. Furthermore, the inherent isolation properties of the concrete material of the support layer 4 effectively prevent moisture from the soil layer 7 from eroding the bottom of the planar layer 6. At the same time, the mortar layer 2 is located above the soil base 1, forming a secondary interception to waterproof the surface layer 3. Together with the strip 17 fixed at both ends of the planar layer 6, it effectively provides multiple layers of protection for both sides of the planar layer 6, isolating the soil layer 7 from erosion of the planar layer 6 from multiple directions, preventing the planar layer 6 from being damaged by moisture, and thus improving its service life.
[0045] The above are merely optional embodiments of this disclosure and are not intended to limit this disclosure. Various modifications and variations can be made to this disclosure by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this disclosure should be included within the scope of protection of this disclosure.
