Description

Technical Field

[0001] The present invention relates to the technical field of deep-sea ancillary building engineering, in particular to the integrated rapid assembly and construction of offshore floating airport runways and the improvement of aircraft take-off and landing capabilities, and more particularly to a modular assembled floating aircraft runway structure for deep-sea islands and reefs and a rapid assembly method thereof. Background Art

[0002] At present, the construction of traditional deep-sea island and reef airports is still mainly based on the island and reef land. The existing problems are detailed as follows:

[0003] 1. Engineering limitations due to the small size of islands and reefs: The land area of ​​a typical island or reef is often less than 0.5 square kilometers, which is difficult to meet the standard runway length required by modern fighter jets. Existing solutions mostly rely on land reclamation, but every 100-meter runway extension requires approximately 30,000 cubic meters of land reclamation, which increases engineering costs exponentially and severely limits runway length. Furthermore, necessary facilities such as control towers, hangars, and fuel depots occupy limited space, resulting in runway clearance areas that do not meet ICAO standards and restricting the construction space for airport runways.

[0004] 2. Uneven runway settlement: Currently, artificial islands and reefs primarily use coral sand filling and other processes to create their land foundations. Coral sand particles are highly angular and poorly graded, making them prone to fragmentation and reorganization under dynamic loads. This foundation characteristic leads to particularly severe runway settlement. In severe cases, the runway surface can develop wavy deformations, seriously impacting aircraft taxiing safety.

[0005] 3. Complex construction and maintenance, unable to quickly respond to wartime conditions: The existing construction model cannot meet the flexibility requirements of modern warfare for infrastructure. Traditional cast-in-place concrete runways require more than 12 months from foundation treatment to commissioning. Each process relies on large-scale machinery and equipment, such as concrete pumps and pavers, which are difficult to dispatch in the island and reef environment, and cannot achieve a continuous use mode of "maintenance during combat."

[0006] The cumulative effect of these problems leads to a greater risk of use of existing island and reef airports in a wartime environment. Therefore, based on the existing environmental conditions of the islands and reefs, in order to ensure the manpower in wartime, it is imperative to study the construction of simple floating runways around deep and remote islands and reefs. Summary of the Invention

[0007] In view of the shortcomings of the existing technology, the present invention provides a modular assembled floating aircraft runway structure for deep-sea islands and reefs and a construction method thereof. By improving the runway structure design, the problems of complex construction and maintenance of traditional deep-sea island and reef airport runways and insufficient wind and wave resistance are solved to ensure the manpower in wartime.

[0008] The technical solutions of the present invention are as follows:

[0009] The present invention first provides a modular assembled floating aircraft runway structure for deep-sea islands and reefs, comprising: a wave-proof counterweight structure, a self-leveling floating structure, a detachable damping support structure, and a pavement layer, wherein:

[0010] The wave-proof counterweight structure is arranged in the water and consists of multiple groups of wave-proof counterweight blocks, and the multiple groups of wave-proof counterweight blocks are connected to the self-leveling floating structure through suspension ropes;

[0011] The self-leveling floating structure is arranged in the water and is composed of a plurality of prefabricated buoy assemblies. The plurality of prefabricated buoy assemblies correspond one-to-one to the plurality of wave-proof counterweight blocks. The prefabricated buoy assemblies are composed of a prefabricated sleeve and a buoy embedded in the prefabricated sleeve. The prefabricated sleeve body is a hollow cylinder wall with horizontal buoyancy plates extending on both sides. The hollow cylinder wall cavity is partially filled with water, and the water surface is flush with the horizontal buoyancy plates, so that the self-leveling floating structure can remain horizontal under wind and wave loads.

[0012] The detachable damping support structure is composed of a runway panel and dampers. The runway panel is laid above the self-leveling floating structure. Two ends of multiple groups of dampers are respectively connected to the runway panel and the horizontal buoyancy plate. Multiple groups of runway panels are interconnected to form a continuous runway.

[0013] The pavement layer is laid as a whole on the pavement panel to form a continuous runway surface.

[0014] In an optional embodiment, the wave-proof counterweight block is provided with multiple groups of transverse and longitudinal through holes to reduce the shaking effect of waves or undercurrents on the counterweight block.

[0015] In an optional embodiment, a plurality of lifting ears are provided on the top of the wave-proof counterweight block, and a plurality of lifting hooks are correspondingly provided on the bottom of the horizontal buoyancy plate, and both ends of the lifting rope are respectively connected to the lifting ears and the lifting hooks.

[0016] In an optional embodiment, the horizontal buoyancy plates are arranged at 1 / 2 height on both sides of the prefabricated sleeve, and the water level line of the water injection in the cavity of the sleeve wall is at 1 / 2 height.

[0017] In an optional embodiment, the float is a cylindrical structure that is adapted to the size of the prefabricated sleeve and is sleeved inside the prefabricated sleeve.

[0018] In an optional embodiment, the extension width of the horizontal buoyancy plate is flush with the width of the runway panel, so that multiple groups of the self-leveling floating structures abut against each other, thereby increasing the overall stability of the runway.

[0019] In an optional embodiment, the side of the road panel is provided with a connection hole and a disassembly groove, and two adjacent groups of the road panels are connected through the disassembly groove and connected by high-strength bolts through the connection hole to form a continuous whole.

[0020] In an optional embodiment, the damper is a spring damper.

[0021] In an optional embodiment, the pavement layer is paved with a new type of medium-high viscosity asphalt material. The new type of medium-high viscosity asphalt material forms a microscopic three-dimensional fiber network during the preparation process and is filled in the joints between multiple groups of the pavement panels during paving to improve the structural strength, stability and deformation recovery performance of the pavement layer.

[0022] The present invention further provides a method for rapidly assembling the modular assembled floating aircraft runway structure for deep-sea islands and reefs, comprising the following steps:

[0023] Connecting and fixing the road panel with multiple groups of the spring dampers and the prefabricated sleeves;

[0024] embedding the buoy into the prefabricated sleeve;

[0025] The wave-proof counterweight blocks are lifted by using the lifting lugs and the lifting ropes, and are fixedly connected to the horizontal buoyancy plates one by one, and the assembly of the single module is completed;

[0026] Lifting the assembled multiple modules to the sea surface and positioning them;

[0027] Multiple groups of the road panels are connected to each other through the disassembly and assembly slots, the connection holes of adjacent road panels are aligned, and high-strength bolts are tightened hole by hole;

[0028] The pavement layer is laid on the surface of the spliced ​​pavement panels to enhance the flexibility, impact resistance and flatness of the runway.

[0029] The beneficial effects of the present invention relative to the prior art are:

[0030] 1. Strong stability against wind and waves: The present invention combines a wave-proof counterweight structure with a self-leveling floating structure, which can not only ensure the overall stability of the floating runway, but also reduce the impact of waves or undercurrents, effectively improving the anti-swaying ability of the upper floating structure.

[0031] 2. Strong anti-overturning ability: The self-leveling floating structure of the present invention provides strong buoyancy while having anti-overturning ability, ensuring the safety of the runway under different sea conditions.

[0032] 3. Strong impact resistance: The components of the present invention are connected in a high-strength manner to form an overall force-bearing system, which can effectively resist the impact load during aircraft takeoff and landing, while weakening the impact of waves and strong winds on the runway.

[0033] 4. Modular, Rapid Assembly and Maintenance: This invention utilizes a prefabricated, removable design, enabling rapid assembly and installation of the runway foundation. This facilitates construction, disassembly, and subsequent repair and replacement, significantly improving construction efficiency. Furthermore, the novel medium- and high-viscosity asphalt used in the pavement layer eliminates the need to consider the shrinkage and expansion effects of cast-in-place concrete runways, meeting the specific requirements of rapid construction and convenient maintenance.

[0034] 5. Adaptability to various sea environments: The present invention has multi-scenario applicability and is not only suitable for still water areas, but can also maintain stability in sea areas with strong winds and waves.

[0035] 6. Saving land resources and strong applicability: The present invention does not occupy valuable land resources on islands or coasts, is suitable for rapid deployment at sea, and can meet the take-off and landing needs of larger aircraft.

[0036] In summary, the present invention has excellent impact resistance, stability and environmental adaptability on the basis of rapid assembly and construction, and is suitable for aircraft take-off and landing requirements in various sea conditions.

[0037] It should be understood that the implementation of any embodiment of the present invention does not mean that multiple or all of the above-mentioned beneficial effects must be possessed or achieved at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0051] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clearly understood, the embodiments of the present invention are further described in detail below in conjunction with the embodiments and drawings. Here, the illustrative embodiments of the present invention and their descriptions are used to explain the present invention, but are not intended to limit the present invention.

[0055] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature identified as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, "plurality" means two or more, unless otherwise specifically defined.

[0056] The present invention mainly provides a modular assembled floating aircraft runway structure for deep-sea islands and reefs and a rapid assembly method thereof. Figure 1-4 As shown, the structure mainly includes a wave-breaking counterweight structure 2, a self-leveling floating structure 1, a detachable damping support structure 4 and a pavement layer 5 according to its functions.

[0057] Specifically, the wave-proof counterweight structure 2 is arranged in the water, and the depth thereof is determined according to the actual situation and wave-proof requirements. The wave-proof counterweight structure 2 plays a wave-proof role on the one hand, and is composed of multiple groups of wave-proof counterweight blocks 21. On the other hand, it is used to connect and limit the position of the self-leveling floating structure 1. The multiple groups of wave-proof counterweight blocks 21 are connected to the self-leveling floating structure 1 through the suspension ropes 3, so that the self-leveling floating structure 1 is maintained and stabilized at a predetermined position above the water.

[0058] The self-leveling floating structure 1 is arranged in the water and is correspondingly located above the wave-breaking counterweight structure 2. The self-leveling floating structure 1 is composed of a plurality of groups of prefabricated buoy assemblies, and the plurality of prefabricated buoy assemblies correspond one to one with the plurality of groups of wave-breaking counterweight blocks 21. Each group of prefabricated buoy assemblies is composed of a prefabricated sleeve 11 and a buoy 12. The main body of the prefabricated sleeve 11 is a hollow cylinder wall 111, and the buoy 12 is embedded in the hollow cylinder wall 111. Horizontal buoyancy plates 112 are extended on both sides of the hollow cylinder wall 111, and the cylinder wall cavity of the hollow cylinder wall 111 is partially filled with water. The water surface is flush with the horizontal buoyancy plates 112, so that the self-leveling floating structure 1 can remain horizontal under wind and wave loads. It is easy to understand that the self-leveling floating structure 1 mainly plays a floating bearing role, and supports the upper aircraft take-off and landing loads and impacts through the stable supporting force and stability provided by the plurality of groups of prefabricated buoy assemblies.

[0059] The detachable damping support structure 4 is composed of a damper 41 and a runway panel 42. The runway panel 42 is laid on top of the self-leveling floating structure 1. The two ends of multiple groups of dampers 41 are respectively connected to the runway panel 42 and the horizontal buoyancy plate 112. Multiple groups of runway panels 42 are connected to each other to form a continuous runway.

[0060] The pavement layer 5 is entirely laid on the pavement panel 42 to form a continuous runway surface.

[0061] Reference Figure 2 The wave-proof counterweight block 2 is a rectangular parallelepiped structure, but can also be other reasonable shapes, such as regular polygonal columns, to facilitate processing and manufacturing. Of course, it can also be made into other regular or irregular interconnected connection structures, such as mortise and tenon connections, tongue and groove connections, etc., to facilitate on-site layout.

[0062] In this embodiment of the present invention, multiple groups of longitudinal and transverse through-holes 22 are evenly distributed on the wave-proof counterweight 2 to mitigate the impact of waves or undercurrents. In this embodiment, the through-holes 22 are circular and can be arranged in an array or diamond pattern, for example. Of course, the through-holes 22 can also have other suitable shapes, and their size, number, and arrangement can be adjusted according to the intensity of the wave impact load in the airport waters.

[0063] Furthermore, the surface of the wave-proof counterweight block 2 is provided with a lifting lug 23. In this embodiment, the lifting lug 23 is located on the long side of the top surface of the wave-proof counterweight block 2. The block is evenly divided into four or more key sections along its long side. A pair of lifting lugs 23 are symmetrically provided on each section to ensure the stability of the connection between the wave-proof counterweight block 2 and the self-leveling floating structure 1. Of course, the specific arrangement of the lifting lug 23 can also adopt any other reasonable method as long as the reliability of the connection is met.

[0064] Reference Figure 3, multiple groups of prefabricated pontoon assemblies are composed of a prefabricated sleeve 11 and a pontoon 12. The prefabricated sleeve 11 includes two parts: a hollow cylinder wall 111 and a horizontal buoyancy plate 112. The horizontal buoyancy plate 112 is symmetrically extended on both sides of the hollow cylinder wall 111, and the connection is fixed by welding or other connection methods to form an integral structure. Of course, the hollow cylinder wall 111 can also be replaced by other reasonable structures such as regular hollow polyhedral prisms. The horizontal buoyancy plate 112 is set at 1 / 2 height on both sides of the hollow cylinder wall 111, and the water level line of the water injection in the cylinder wall cavity is at 1 / 2 height. Under wind and wave loads, the horizontal buoyancy plates 112 on both sides of the hollow cylinder wall 111 correct the buoyancy difference on both sides through the lever effect, and combine the buoyancy-gravity balance system of the water body in the cylinder wall cavity of the hollow cylinder wall 111 to control the lateral tilt and longitudinal rotation of the self-horizontal floating structure 1, thereby realizing the self-leveling correction function.

[0065] The horizontal buoyancy plate 112 is a rectangular plate, and its extended width is flush with the runway panel 42. After the runway is assembled, multiple groups of prefabricated buoyancy components abut against each other to form a continuous whole with longitudinal rigidity, thereby ensuring the longitudinal stability of the runway.

[0066] The buoy 12 is a cylindrical structure that matches the size of the hollow cylinder wall 111 and is sleeved in the hollow cylinder wall 111. The surface of the buoy 12 is tightly fitted with the inner surface of the hollow cylinder wall 111 and there is a contact force, making it difficult to slip off from the inside of the hollow cylinder wall 111.

[0067] Furthermore, a lifting hook (not shown) is provided at the bottom of the prefabricated sleeve 11. The position of the lifting hook corresponds to the lifting ear 23 on the surface of the wave-proof counterweight 2. The two ends of the lifting rope 3 are connected to the lifting ear 23 and the lifting hook respectively.

[0068] The hollow cylindrical wall 111 is made of high-strength steel, but can also be made of other materials such as alloys. It can be welded from steel plates or other metal profiles to ensure that the self-leveling floating structure 1 has sufficient strength to withstand the impact of wind, waves, and undercurrents. During fabrication, the hollow cylindrical wall cavity can be directly filled with water and then sealed. Alternatively, a water inlet can be reserved for temporary water filling and sealing during on-site assembly.

[0069] Reference Figure 4 The detachable damping support structure 4 consists of a pavement panel 42 and a damper 41. Multiple groups of dampers 41 are evenly arranged on both sides of the hollow cylinder wall 111, and their upper and lower ends are respectively connected to the pavement panel 42 and the prefabricated sleeve 11. In this embodiment, three groups of dampers 41 are evenly distributed on each side of the horizontal buoyancy plate 112, and the dampers 41 are perpendicular to the horizontal buoyancy plate 112. The dampers 41 are spring dampers. Of course, the type, quantity and arrangement of the dampers 41 can be flexibly adjusted according to the load characteristics of the airport sea area. For example, in the calm sea area near the coast, rubber dampers can be arranged at the head and tail ends of each side of the horizontal buoyancy plate 112 to meet the design requirements.

[0070] Reference Figure 5 The road panel 42 is a rectangular plate with disassembly slots 423 and connection holes 422 on its side. The disassembly slots 423 can be structurally designed as protruding extension edges of the first group of adjacent side edges of the road panel 42 and recessed grooves of the second group of adjacent side edges. The extension width of the extension edge is adapted to the depth of the groove, and the connection holes 422 are evenly distributed on the edges of the extension edge and the groove to form a uniform connection and stress release structure. The two adjacent groups of road panels 42 are connected through the disassembly slots 423, and then high-strength bolts 421 are passed through the connection holes 422 and fastened to form a continuous whole. In this embodiment, the disassembly slots 423 have 8 connection holes 422 evenly distributed longitudinally and 7 connection holes 422 evenly distributed transversely. Of course, the number and distribution of the connection holes 422 can be reasonably adjusted.

[0071] Furthermore, the runway panel 42, the damper 41, and the prefabricated sleeve 11 are fixed into a whole by strong connection methods such as high-strength bolts, so as to resist the real-time impact load on the runway during aircraft takeoff and landing, greatly reduce the impact of sea waves, wind loads, etc. on the floating runway, and improve the overall performance of the assembled floating runway.

[0072] Optionally, the road panel 42 is made of high-strength steel, or other high-performance materials with a certain strength. The high-strength steel used in this embodiment has high strength, good toughness, and corrosion resistance, and can fully adapt to high-chloride seawater environments, thereby improving the durability of the structure.

[0073] Continue to refer to Figure 1 、 Figure 6 The pavement layer 5 is laid integrally on the assembled road slabs 42. In this embodiment of the present invention, an asphalt material made with a novel medium-to-high viscosity asphalt modifier is used. During the mixing process in the production unit, the asphalt material softens at high temperatures and is stretched into a three-dimensional fiber network at the microscopic level. This network is evenly distributed throughout the pavement surface, acting like steel bars to enhance the asphalt mixture's molded strength, stabilize its structure, and enhance deformation recovery. Furthermore, unlike traditional cast-in-place concrete runway surfaces, this asphalt material eliminates the need to consider concrete shrinkage and expansion, making it more suitable for disassembly and assembly, meeting the specific requirements of rapid assembly, construction, and maintenance.

[0074] Reference Figure 8 The flowchart shown in the figure is combined with Figure 7 , the rapid assembly method of the floating runway includes the following steps:

[0075] S10: The road panel 42, the plurality of dampers 41 and the prefabricated sleeve 11 are firmly mechanically connected and fixed one by one by fastening with high-strength bolts, etc., to ensure that they form a composite foundation unit with good rigidity and toughness;

[0076] S20: Accurately embed the factory-prefabricated buoy 12 into the inner cavity of the prefabricated sleeve 11 to ensure that the buoy 12 is stably positioned and fits tightly with the prefabricated sleeve 11;

[0077] S30: Using a large crane ship or tower crane or other lifting equipment, the wave-breaking counterweight blocks 2 are steadily lifted to the predetermined installation position through the lifting lugs 23 and the lifting ropes 3, and are connected one by one to the lifting hooks of the upper self-leveling floating structure 1. The assembly of the single module is completed;

[0078] S40: Using a precise ocean positioning system and ship control system, the assembled and qualified modules are transported to the offshore airport runway construction area. The connected modules are positioned and steadily placed on the sea surface. The modules are then precisely adjusted and positioned in three-dimensional space and in elevation to ensure that the relative positions of the modules and the overall layout meet the designed runway geometry requirements.

[0079] S50: Each individual module is spliced ​​together through the assembly and disassembly slots 423 of the runway panels 42. During the splicing process, ensure that the extension plates of adjacent assembly and disassembly slots 423 are vertically aligned with the grooves, and that the connection holes 422 at the joints of two adjacent runway panels 42 precisely overlap. High-strength bolts 421 are inserted through each hole and tightened according to the designed tightening force, connecting the adjacent runway panels 42 into a single unit. After the individual modules are connected, the horizontal buoyancy plates 112 of adjacent individual modules under the runway abut against each other, forming a continuous structural framework with sufficient overall rigidity and impact resistance.

[0080] S60: After all slabs 42 and their connection points, which constitute the main load-bearing structure of the runway, have been completed and thoroughly inspected and accepted, the paving of the runway's pavement layer 5 begins. Based on design requirements, a pavement layer 5 material with excellent flexibility, strong impact resistance, and durable wear and tear, such as a new medium- to high-viscosity asphalt, is selected and prepared. Using a paver, small vibratory compaction equipment, specialized adhesives, and manual paving, the pavement layer 5 material is evenly and densely laid on the top surfaces of all slabs 42, ensuring a dense filling and a smooth surface. The pavement layer 5 provides a smooth running surface for aircraft takeoff and landing. Its excellent flexibility effectively absorbs and dissipates the tremendous impact energy generated during takeoff and landing, significantly increasing the runway's overall impact resistance and fatigue life. It also works in conjunction with the substructure to ensure the runway's long-term stability and safety under various extreme environmental conditions.

[0081] In particular, the size of the individual modules can be customized to the dimensions of the new runway, and combined with the splicing and hoisting construction method, a detachable, impact-resistant floating aircraft runway is formed. At the same time, the detachable nature of the assembly simplifies the construction process and provides greater construction convenience.

[0082] The invention has the advantages of short construction period, saving construction area, convenient assembly and disassembly, flexibility and maneuverability, strong anti-explosion ability, and good adaptability to the sea areas near islands and reefs.

[0083] The principle of the present invention is:

[0084] Wave-breaking counterweight structure 2: The guiding effect of the through-hole 22 allows the waves to partially pass through the through-hole 22 when hitting the wave-breaking counterweight block 2, reducing the direct impact force of the waves, and local vortices are formed when the waves pass through the through-hole 22, and part of the kinetic energy is converted into turbulent energy and dissipated, which weakens the lateral driving force on the wave-breaking counterweight block 2. At the same time, the instantaneous pressure difference on both sides of the wave-breaking counterweight block 2 is also effectively reduced, thereby weakening the overturning moment caused by pressure imbalance.

[0085] Self-leveling floating structure 1: Under wind and wave loads, the gravity generated by the water-filled portion of the hollow cylindrical wall 111 and the air buoyancy of the unfilled portion form a dynamic balance, forming a buoyancy-gravity balance system. The symmetrically extended horizontal buoyancy plates 112 act as physical levers. When one side is pressed downward by an external force, the volume of the horizontal buoyancy plates 112 on the downward-pressing side increases, and the corresponding buoyancy on the downward-pressing side also increases. The horizontal buoyancy plates 112 on the opposite side are lifted, resulting in a decrease in the buoyancy on the lifted side. The two create a restoring torque that propels the system back to the right position, forming a buoyancy difference correction mechanism. The horizontal buoyancy plates 112 on both sides correct the buoyancy difference on both sides through the lever effect. Combined with the buoyancy-gravity balance system of the water body in the hollow cylindrical wall 111, they control the lateral tilt and longitudinal rotation of the self-leveling floating structure 1, achieving self-leveling.

[0086] Removable damping support structure 4: When the runway shakes under wind and wave loads, the damper 41 begins to absorb the energy, reducing the impact while strengthening the runway's overall rigidity and stability through its strong connection with the runway panel 42 and prefabricated sleeve 11, helping to maintain the runway's stability. Furthermore, the removable design of the runway panel 42 allows for rapid assembly and installation of the runway foundation, facilitating installation, disassembly, construction, and subsequent maintenance and replacement.

[0087] Pavement layer 5: On the one hand, pavement layer 5 ensures the stability and construction convenience of the runway through the structural advantages of overall paving. On the other hand, it improves the strength, impact resistance and flexible deformation recovery performance of the runway through the characteristics of the material.

[0088] It is easy for those skilled in the art to understand that, under the premise of no conflict, the above preferred solutions can be freely combined and superimposed.

[0089] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
