Description

Technical Field

[0001] This invention relates to the field of port engineering technology, specifically to a mobile wharf structure based on pneumatic support. Background Technology

[0002] A wharf is a structure built along the sea or riverbank specifically for ships or ferries to dock, allowing passengers to embark and disembark, and for cargo to be loaded and unloaded. Traditional wharves mostly use fixed structures (such as pile-foundation wharves or gravity-supported wharves).

[0003] A pile-foundation wharf consists of pile foundations and a superstructure. The load is borne by piles driven into the ground. The superstructure can be beam-slab type, flat slab type, frame type, or pile cap type, etc.

[0004] Gravity wharves are constructed of heavy boulders, concrete blocks, or precast concrete, and rely on the weight of the structure itself and the fill material on it to resist horizontal thrust and vertical loads.

[0005] However, traditional docks have the following drawbacks: It lacks flexibility and cannot adapt to drastic changes in water level (such as tides and floods) or disaster emergency needs.

[0006] The construction is complex, and the pile foundation construction requires long-term underwater operations, which damages the ecological environment and is costly.

[0007] Insufficient stability; existing mobile wharves (such as pontoon wharves) have weak resistance to wind and waves and limited load-bearing capacity. Summary of the Invention

[0008] The purpose of this invention is to provide a mobile wharf structure based on pneumatic support to solve the core contradiction of existing wharves in balancing flexibility, load-bearing capacity and resistance to environmental interference. It has the advantages of high load-bearing capacity, strong resistance to environmental interference and good durability.

[0009] To achieve the above objectives, the present invention provides the following technical solution: a mobile wharf structure based on pneumatic support, comprising a pneumatic support module layer, a deck layer, a concrete main body layer, and a connecting and leveling layer.

[0010] The pneumatic support module layer is positioned above the connecting and leveling layer, the concrete main body layer is positioned above the connecting and leveling layer, and the deck layer is positioned above the concrete main body layer. This layered structure ensures that each part has a clearly defined and independent function, facilitating manufacturing, transportation, installation, and subsequent maintenance and replacement. The modular design enhances the structure's versatility and scalability, allowing for flexible adjustment of parameters for each layer according to different dock sizes and usage scenarios, thus reducing customization costs.

[0011] In a preferred embodiment of the present invention, the pneumatic support module layer includes a main airbag layer, a compensating airbag layer, and a hydraulic damping cavity. Both the main airbag layer and the compensating airbag layer are connected above the hydraulic damping cavity, with the compensating airbag layer connected to the outside of the main airbag layer. The main airbag layer and the compensating airbag layer are used for inflation to provide support, while the hydraulic damping cavity is used to fill with damping material. The combined design of the main and auxiliary airbag layers improves the comprehensiveness and stability of the support, preventing structural deformation in edge areas due to insufficient support. The hydraulic damping cavity effectively reduces vibration and impact from wind, waves, and ship berthing, protecting the main structure of the dock and upper-level equipment, and extending the overall service life.

[0012] In a preferred embodiment of the present invention, the main airbag layer comprises several honeycomb-shaped independent air chambers, each connected to a first solenoid valve, and the outer surface of each independent air chamber is coated with a self-healing coating. The honeycomb-shaped independent air chambers enhance the support effect, and the first solenoid valves are used by the central air supply system to inflate each independent air chamber. The self-healing coating material contains 3%-5% by mass of nano-silica particles. The independent air chamber design reduces the impact of a single air chamber failure on the overall support, improving structural safety; precise pressure control allows the wharf to adapt to different load conditions, reducing structural stress concentration; and the self-healing coating extends the service life of the airbags, reducing maintenance costs.

[0013] In a preferred embodiment of the present invention, a raised rubber strip is connected to the top of the compensating airbag layer, and a miniature air pump is equipped on the compensating airbag layer. The miniature air pump is used to inflate the compensating airbag layer, and the inflated airbag expands and presses against the raised rubber strip. The independent miniature air pump makes the adjustment of the compensating airbag layer more flexible and can quickly respond to load changes; the pressing design of the raised rubber strip enhances the connection and sealing between the compensating airbag layer and the upper structure, prevents water from seeping into the structural gaps, and at the same time improves the interlayer connection stiffness.

[0014] In a preferred embodiment of the present invention, the hydraulic damping cavity is filled with magnetorheological fluid, and a second solenoid valve is connected below the hydraulic damping cavity. The viscosity of the magnetorheological fluid inside the hydraulic damping cavity is adjusted by the second solenoid valve. The damping effect can be adjusted in real time according to different vibration intensities, allowing the damping cavity to adapt to various dynamic conditions such as wind and waves and ship impacts, thereby improving the vibration resistance and stability of the wharf. The rapid response characteristics of the magnetorheological fluid ensure that it can exert its damping effect in a timely manner when vibration occurs, protecting the structure from impact damage.

[0015] As a preferred embodiment of the present invention, the deck layer integrates several piezoelectric power generation units, which are used to convert the vibration energy of the airbags in the pneumatic support module layer into electrical energy. This realizes the recovery and utilization of idle vibration energy in the environment, reduces the energy consumption demand of the dock, and conforms to the concept of green energy conservation; the integrated design does not occupy additional space, enhances the functional added value of the dock structure, and reduces dependence on external power supply systems.

[0016] In a preferred embodiment of the invention, prestressed tendons and holes are pre-embedded within the concrete main layer. An airbag docking groove is formed at the bottom of the concrete main layer, and a sealing rubber strip is fixed inside the groove. A raised rubber strip is embedded within the airbag docking groove. A concrete layer covers the surface of the concrete main layer, and a fiber optic stress sensor is pre-embedded inside the concrete main layer near its outer side. When the airbag is inflated, it expands and presses against the raised rubber strip, achieving a watertight connection in conjunction with the sealing rubber strip. The prestressed tendon design enhances the load-bearing capacity and durability of the concrete main layer, reducing crack formation. The sealing structure effectively prevents water infiltration, protecting the underlying pneumatic module and making it suitable for underwater operations at docks. The fiber optic stress sensor enables real-time monitoring of structural stress, facilitating timely detection of safety hazards and improving dock operational safety.

[0017] As a preferred embodiment of the present invention, the joints of the concrete slab are filled with underwater epoxy resin adhesive, the outside of the joint is wrapped with a rubber waterstop, and fiberglass connecting bars are pre-embedded at the joints. This leak-proof design ensures the watertightness of the joints, adapting to the humid and watery working environment of the dock; the fiberglass connecting bars enhance the joint strength, preventing damage to the joints due to temperature changes and loads, and extending the service life of the concrete slab.

[0018] In a preferred embodiment of the present invention, the connecting leveling layer includes a leveling shim set. The leveling shim set is made of high-strength polymer shims and is used to compensate for unevenness of the foundation, reducing local pressure overload on the airbag. This solves the problem of uneven stress caused by uneven foundation, protects the airbag from damage by local overload, and improves the reliability of the pneumatic support module layer. The material properties of the high-strength polymer shims make them adaptable to the complex environment of the dock, not prone to aging and deformation, and ensure long-term stability of the leveling effect.

[0019] Compared with the prior art, the beneficial effects of the present invention are: This invention provides a stable and safe dock structure. The honeycomb-shaped independent air chambers reduce the impact of single-chamber failures, the main and auxiliary airbag combination avoids weak edge support, the magnetorheological fluid damping system can reduce vibration impact in real time, and the double sealing and leak-proof seam design is suitable for humid environments. Fiber optic sensors can also monitor potential hazards in real time. Its adaptability and durability are outstanding. Leveling gaskets protect the airbags from localized overload, the self-healing coating extends the airbag life, and prestressed ribs and fiberglass ribs strengthen the structure's crack resistance. It also boasts green and economical features: piezoelectric units recover vibration energy to reduce energy consumption, the layered modular design facilitates production and maintenance, and it can be flexibly adapted to different scenarios, reducing customization costs.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] In the description of this invention, it should be noted that the terms "vertical," "upper," "lower," "horizontal," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0024] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0025] Please see Figure 1 The present invention provides a technical solution: a mobile wharf structure based on pneumatic support, including a pneumatic support module layer 100, a deck layer 200, a concrete main body layer 300 and a connecting and leveling layer 400.

[0026] Above the pneumatic support module layer 100, a connecting and leveling layer 400 is installed. Above the connecting and leveling layer 400, a concrete main body layer 300 is installed. Above the concrete main body layer 300, a deck layer 200 is installed. A layered modular design is adopted, with the pneumatic support module layer 100 serving as the core support unit to provide basic buoyancy and support force. The connecting and leveling layer 400 supports the upper and lower structures and eliminates flatness errors caused by installation and foundation. The concrete main body layer 300, due to its material properties, bears the main load and provides a stable carrier for the upper structure. The deck layer 200 supplements the specialized functions required for wharf use. Each layer forms a collaborative working system through a reasonable force transmission path.

[0027] For further details, please refer to Figure 2-4 The pneumatic support module layer 100 includes a main airbag layer 101, a compensating airbag layer 102, and a hydraulic damping cavity 103. Both the main airbag layer 101 and the compensating airbag layer 102 are connected above the hydraulic damping cavity 103, with the compensating airbag layer 102 connected to the outside of the main airbag layer 101. The main airbag layer 101 and the compensating airbag layer 102 are inflated to provide support, while the hydraulic damping cavity 103 is filled with damping material. The main airbag layer 101, as the primary support component, provides core support force through the gas pressure generated by its inflation. The compensating airbag layer 102, located on the outside, can specifically compensate for weak support areas at the edges of the main airbag layer 101, forming a complete support surface. The damping material within the hydraulic damping cavity 103 absorbs external vibration energy through its own viscous deformation, reducing vibration transmission.

[0028] Furthermore, the main airbag layer 101 comprises several honeycomb-shaped independent air chambers (each chamber with a pressure resistance ≥1.5MPa). Each independent air chamber is connected to a first solenoid valve 1012, and the outer surface of each independent air chamber is coated with a self-healing coating 1013. The honeycomb-shaped independent air chambers enhance the support effect. The first solenoid valves 1012 are used by the central air supply system to inflate each independent air chamber. The self-healing coating 1013 contains 3%-5% by mass of nano-silica particles, which can automatically seal damage with a diameter ≤3mm. The honeycomb structure can evenly distribute the load to each independent air chamber, and improve the support stiffness and stability by utilizing the structural mechanical properties; the first solenoid valve 1012 realizes the central system to accurately control the inflation of individual air chambers, which is convenient to adjust the pressure of each air chamber according to the load distribution; the nano silica particles in the self-healing coating 1013 can enhance the density and wear resistance of the coating, and when microcracks appear in the coating, the interaction between particles and the coating's own properties can realize the self-healing of cracks.

[0029] Furthermore, a raised rubber strip 1021 is connected to the top of the compensation airbag layer 102, and a miniature air pump (response time < 0.5 seconds) is equipped on the compensation airbag layer 102. The miniature air pump is used to inflate the compensation airbag layer 102, and after the airbag is inflated, it expands and presses the raised rubber strip 1021 tightly. The miniature air pump provides independent inflation power for the compensation airbag layer 102, and the airbag pressure can be flexibly adjusted according to actual support requirements; the radial force generated after the airbag is inflated tightly presses the raised rubber strip 1021 against the surface of the mating structure, and the elastic deformation of the rubber fills the gap between the joints.

[0030] Furthermore, the hydraulic damping cavity 103 is filled with magnetorheological fluid, and a second solenoid valve 1031 is connected below the hydraulic damping cavity 103. The viscosity of the magnetorheological fluid inside the hydraulic damping cavity 103 is adjusted by the second solenoid valve 1031. The magnetorheological fluid can achieve rapid and reversible viscosity changes under the action of a magnetic field. The second solenoid valve 1031 adjusts the viscosity characteristics of the magnetorheological fluid by controlling the magnetic field strength. When the dock is subjected to vibration and impact, the high-viscosity magnetorheological fluid can significantly increase the damping force, hinder the flow of fluid in the cavity, and thus absorb vibration energy.

[0031] For further details, please refer to Figure 2 The deck layer 200 integrates several piezoelectric power generation units 201, which are used to convert the vibration energy of the airbags in the pneumatic support module layer 100 into electrical energy. Utilizing the positive piezoelectric effect of piezoelectric materials, when the pneumatic support module layer 100 vibrates due to external loads or environmental factors, the piezoelectric crystals in the piezoelectric power generation units 201 undergo mechanical deformation, thereby generating induced charges at both ends of the crystals, realizing the conversion of vibration mechanical energy into electrical energy. The generated electrical energy can be stored through an energy storage device or directly supplied to low-voltage equipment.

[0032] For further details, please refer to Figure 5-6 The concrete main layer 300 is pre-embedded with prestressed tendons 301 and holes 302 (hole diameter 200mm, reducing self-weight by 15%). An airbag docking groove 303 is provided at the bottom of the concrete main layer 300, and a sealing rubber strip 304 is fixed inside the airbag docking groove 303. A raised rubber strip 1021 is embedded in the airbag docking groove 303. A concrete layer 305 covers the surface of the concrete main layer 300. An optical fiber stress sensor 306 is pre-embedded inside the concrete main layer 300 near the outer side. The concrete slab uses lightweight aggregate concrete (density ≤1600kg / m³, strength C35), prefabricated into 3m×6m standard modules. After the airbag is inflated, it expands and presses against the raised rubber strip 1021, achieving a watertight connection in conjunction with the sealing rubber strip 304. The pre-embedded prestressed tendons 301 can form pre-compression stress inside the concrete main layer 300 to offset the tensile stress generated by external loads and improve the crack resistance of the structure; the interlocking structure of the airbag docking groove 303 and the raised rubber strip 1021 forms a mechanical seal base, which, together with the elastic compression of the sealing rubber strip 304, constructs a double sealing system; the fiber optic stress sensor 306 utilizes the interference effect of light to monitor the stress changes of the concrete main layer 300 in real time and realize structural health monitoring.

[0033] Furthermore, the joints of the concrete slabs are filled with underwater epoxy resin adhesive 307, and the outside of the joints is wrapped with rubber waterstops 308. Fiberglass reinforcing bars 309 are pre-embedded at the joints. The underwater epoxy resin adhesive 307 has excellent underwater adhesion and corrosion resistance, filling the joint gaps and forming a strong bond. The rubber waterstop 308 utilizes its own elasticity to form an elastic seal at the joints, offsetting gaps caused by structural deformation. The fiberglass reinforcing bars 309 enhance the integrity of the joints, transferring stress from adjacent concrete slabs and reducing the risk of joint cracking.

[0034] For further details, please refer to Figure 2 The leveling layer 400 includes a leveling shim group 401. The leveling shim group 401 uses high-strength polymer shims (thickness adjustable from 10-50mm). The leveling shim group 401 is used to compensate for unevenness of the foundation and reduce local pressure overload on the airbag. The high-strength polymer shims have the characteristics of high strength and low deformation. By increasing or decreasing the number of shims or adjusting the position of the shims, the unevenness error of the foundation surface can be accurately compensated, so that the load of the concrete main layer 300 can be evenly transferred to the pneumatic support module layer 100; the flat stress surface can avoid excessive pressure in local areas of the airbag due to load concentration.

[0035] Please see Figure 7During dock construction, an air cushion plow device 500 was used to remove silt from the foundation and lay a temporary air cushion layer. When hoisting the deck layer 200, the main airbag layer 101 was simultaneously inflated, with pressure feedback controlling the docking gap to <2mm. Extreme working conditions were simulated using a digital twin system to optimize the airbag pressure parameters. The air cushion plow device 500 includes a high-pressure water nozzle 501 and a foldable air cushion 502, with a load-bearing capacity ≥8t / m² after deployment.

[0036] This mobile dock adopts a layered, modular, and collaborative design, with pneumatic support as the core. Through complementary functions of each layer, it achieves stable support, dynamic adjustment, and safe operation.

[0037] The main airbag layer 101 distributes the load through honeycomb-shaped independent air chambers 1011. The central air supply system achieves precise inflation of each air chamber through the first solenoid valve 1012, using gas pressure to provide basic support. The compensation airbag layer 102 is independently supplied with air by a micro air pump. After inflation, it is reinforced with edge support and sealing by a raised rubber strip 1021. The magnetorheological fluid filled in the hydraulic damping chamber 103 can change the viscosity by adjusting the magnetic field strength through the second solenoid valve 1031, using viscous deformation to absorb vibration energy and weaken external impact.

[0038] High-strength polymer leveling shim set 401 is used. By increasing or decreasing the number of shims or adjusting their position, the unevenness of the foundation is precisely compensated, so that the load of the concrete main layer 300 is evenly transferred to the pneumatic support module layer 100, avoiding local pressure overload of the airbag and constructing a flat and stable force transmission path.

[0039] The internally embedded prestressed tendons 301 form pre-compression stress to offset the tensile stress generated by external loads and improve crack resistance; the bottom airbag docking groove 303 is fitted with the raised rubber strip 1021 of the compensation airbag layer 102, and together with the sealing rubber strip 304 in the groove, a double watertight seal is formed; the internally embedded fiber optic stress sensor 306 uses the light interference effect to monitor the changes in structural stress in real time and realize health monitoring; the concrete slab joints are filled with underwater epoxy resin adhesive 307, wrapped with rubber waterstop 308, and pre-embedded with glass fiber connecting bars 309 to enhance the integrity and watertightness of the joints.

[0040] The integrated piezoelectric power generation unit 201 utilizes the positive piezoelectric effect of piezoelectric materials to convert the mechanical deformation generated by the vibration of the pneumatic support module layer 100 into induced charges, thereby realizing the conversion of vibration energy into electrical energy. The generated electrical energy can be stored or supplied to low-voltage equipment.
