Description

Technical Field

[0001] The present application relates to the field of airport construction, and in particular to the pavement structure of an airport apron. Background Art

[0002] With the development of technology, more and more people choose to travel by plane. In order to meet the needs of passengers, the number of passengers on planes is gradually increasing, which also leads to the increasing weight of aircraft. Therefore, the weight borne by the airport pavement is also increasing, so the load-bearing requirements of airport pavements are also getting higher and higher.

[0003] Most of the existing pavements are formed by steel cages and concrete. After a long time, the land under the pavement will be affected by water and cause the land to collapse, leaving part of the pavement suspended. This greatly reduces the pavement's load-bearing capacity and easily causes the pavement to crack. Utility Model Content

[0004] In order to reduce the collapse of the land under the pavement and improve the bearing capacity of the pavement, the present application provides an airport apron pavement layer structure.

[0005] The above technical objectives of this application are achieved through the following technical solutions:

[0006] An airport apron pavement surface structure comprises a concrete layer, and a waterproof layer is arranged below the concrete layer.

[0007] By adopting the above solution, a waterproof layer is set under the concrete layer, thereby reducing the flow of water into the bottom of the waterproof layer, thereby reducing the probability of collapse of the soil layer under the concrete layer, and improving the strength of the soil layer, thereby reducing the risk of the integrated apron pavement being suspended, thereby achieving the purpose of improving the pavement bearing capacity.

[0008] Optionally, the waterproof layer includes two cloths and one membrane.

[0009] By adopting the above technical solution, "two cloths and one membrane" is a composite geomembrane, which is made of two layers of non-woven geotextiles or polyethylene woven fabrics as the base material, PE as the masterbatch, and plasticizers, anti-aging agents and various auxiliary materials added through hot melt pressing. This membrane can effectively prevent moisture from penetrating into the foundation, avoid erosion and softening of the foundation soil, thereby improving the stability and bearing capacity of the foundation. In addition, two cloths and one membrane can provide a certain tensile strength and anti-deformation ability, which helps to improve the overall performance of the pavement.

[0010] Optionally, oil felt is provided between the waterproof layer and the concrete layer.

[0011] By adopting the above technical solution, the oil felt is a tough and impermeable coil made of animal hair or plant fiber and impregnated with petroleum asphalt. The oil felt has a high waterproof and moisture-proof effect, which can further enhance the water penetration of the airport apron, thereby further improving the stability of the airport apron. At the same time, the oil felt can effectively isolate the concrete layer from the waterproof layer, thereby preventing the concrete layer from affecting the waterproof layer.

[0012] Optionally, a steel mesh is provided in the concrete layer.

[0013] By adopting the above technical solution, before pouring the concrete layer, a steel mesh is first placed in the concrete layer, and then the concrete is poured. The steel mesh can improve the overall strength of the concrete layer, further improve the overall strength of the concrete layer, and thus improve the bearing capacity of the pavement.

[0014] Optionally, the steel mesh is connected to a plurality of vertical steel columns.

[0015] By adopting the above technical solution, vertical steel columns are set to further increase the mixture of steel mesh and concrete, and further enhance the bearing capacity of the concrete layer.

[0016] Optionally, a wire mesh is connected to the side of the vertical steel column facing away from the steel mesh.

[0017] By adopting the above technical solution, when the concrete layer cracks, concrete blocks that are separated from the pavement may be generated. The concrete blocks may enter the aircraft on the apron and affect the personal safety of passengers. The wire mesh can increase the strength and toughness of the concrete, improve the tensile, compressive and shear resistance of the concrete, and thus enhance the overall stability of the hydraulic concrete structure. The wire mesh can also disperse the internal stress of the concrete, reduce the shrinkage and expansion of the concrete, and thus effectively prevent the generation of cracks. Even when the concrete layer cracks, the wire mesh is not easy to break due to its certain toughness, and the concrete block is connected to the wire mesh and will not separate from the pavement, thereby further enhancing the safety of passengers.

[0018] In summary, this application has the following technical effects:

[0019] 1. By setting up a waterproof layer, the water penetration into the soil layer below the airport apron pavement is reduced, thereby reducing the risk of soil collapse below the apron pavement, thereby enhancing the pavement bearing capacity;

[0020] 2. The waterproof penetration performance of the pavement is further enhanced by installing asphalt felt, further reducing the risk of soil collapse under the apron pavement;

[0021] 3. The strength of the concrete layer is strengthened by setting up a steel mesh, thereby enhancing the load-bearing capacity of the pavement. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The present application is further described in detail below with reference to the accompanying drawings.

[0026] Embodiment 1

[0027] Reference Figure 1 The airport apron pavement structure includes a concrete layer 1, and a waterproof layer 4 is arranged below the concrete layer 1. The waterproof layer 4 can effectively prevent the moisture of the airport apron from penetrating into the soil layer below the pavement, thereby preventing the soil layer below the pavement from sinking and forming a cavity, thereby avoiding the pavement being in a suspended state and causing the pavement's load-bearing capacity to be reduced.

[0028] When pouring the concrete layer 1, a steel mesh 2 is first placed in the concrete layer 1, and then concrete is filled into the concrete layer 1. Adding steel bars to the concrete structure can greatly improve the overall strength and bearing capacity of the concrete structure. The steel mesh 2 is tightly combined with the concrete and works together to make the structure more solid and stable. The presence of the steel mesh 2 can also enhance the seismic performance of the concrete. At the same time, the addition of the steel mesh 2 can improve the durability of the concrete, prevent problems such as cracking and peeling of the concrete caused by environmental factors, and extend the service life of the concrete structure. In addition, the addition of steel bars helps to control the deformation of the concrete structure, maintain the shape and size of the structure stable, and ensure the safety and reliability of the building.

[0029] A felt 3 is arranged between the concrete layer 1 and the waterproof layer 4. The felt 3 is a tough and impermeable coil made of animal hair or plant fiber and impregnated with petroleum asphalt. The felt 3 has a high waterproof and moisture-proof effect, which can further enhance the water penetration of the airport apron, thereby further improving the stability of the airport apron. At the same time, the felt 3 can effectively isolate the concrete layer 1 from the waterproof layer 4, thereby preventing the concrete layer 1 from affecting the waterproof layer 4.

[0030] The waterproof layer 4 includes "two cloths and one membrane". "Two cloths and one membrane" is a composite geomembrane, which is made of two layers of non-woven geotextiles or polyethylene woven fabrics as base materials, PE as masterbatch, plasticizers, anti-aging agents and various auxiliary materials added by hot melt pressing. This membrane can effectively prevent moisture from penetrating into the foundation, avoid erosion and softening of the foundation soil, thereby improving the stability and bearing capacity of the foundation, and then improving the bearing capacity of the pavement and reducing cracking of the pavement. At the same time, the two cloths and one membrane can provide a certain tensile strength and anti-deformation ability, which helps to improve the overall performance of the pavement.

[0031] Embodiment 2

[0032] Reference Figure 2 , this embodiment is different from the embodiment 1 in that the steel mesh 2 is provided with a vertical steel bar 5 at the upper end, and a steel mesh 6 is fixedly connected above the vertical steel bar 5, and the steel mesh 6 is within 15-30cm from the upper surface of the pavement. When the pavement cracks, smaller concrete blocks may be generated, and the concrete blocks may enter the interior of the aircraft, thereby creating a safety hazard. The steel mesh 6 has a certain toughness, so the steel mesh 6 is not easy to break. After the pavement cracks, the steel mesh 6 is still connected to the concrete blocks, which can effectively prevent the concrete blocks from entering the interior of the aircraft and causing damage to manpower and material resources. In addition, the steel mesh 6 can increase the strength and toughness of concrete, improve the tensile, compressive and shear resistance of concrete, thereby enhancing the overall stability of the concrete structure. And the steel mesh 6 can play a role in dispersing the internal stress of concrete, reducing the shrinkage and expansion of concrete, thereby effectively preventing the generation of cracks.

After reading this specification, those skilled in the art may make modifications to the present embodiment without any creative contribution as needed, but such modifications are protected by the patent law as long as they are within the scope of the claims of the present application.
