Description

Technical Field

[0001] This invention relates to the field of lock engineering technology, specifically to a steel structure berthing pier. Background Technology

[0002] Berthing piers are specialized facilities installed at the upstream and downstream approach channels of locks for ships to temporarily moor before entering the lock. With regional economic development and the continuous increase in water transport volume, locks, as water transport infrastructure, are becoming increasingly important. As the demand for anchoring services from ships increases, the construction of berthing piers, as safety facilities providing this service, is becoming increasingly crucial. At the same time, the increasing size of ship designs places more stringent technical requirements on ship berthing facilities, driving the development of berthing pier technology.

[0003] Traditional berthing structures in water often employ reinforced buttresses, masonry blocks, plain concrete gravity piers and connected walls, anchored diaphragm walls, and combinations of lower bored pile foundations with upper hollow box-type cast-in-place piers. However, these structures cannot change the weight of the base slab. Therefore, some people have modified the weight by creating compartments inside the berthing pier base slab to add bulk materials or water, as illustrated by Chinese invention patent CN115323991B, which discloses a steel structure berthing pier. However, traditional berthing piers are mostly concrete gravity structures or simple steel pipe pile structures, which are functionally limited, have poor eco-friendliness, are visually bulky, and have poor energy absorption and dissipation effects. Summary of the Invention

[0004] The purpose of this invention is to provide a steel structure berthing pier, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a steel structure berthing pier, comprising a base, a storage structure, a spiral body, an energy dissipation component, and an auxiliary installation structure.

[0006] The storage structure is mounted on the base and is used to add bulk materials or water and adjust the counterweight of the base.

[0007] The spiral body is positioned above the base and is used to decompose and guide the impact force of the ship, and absorb and dissipate energy.

[0008] The energy dissipation components are provided in several units, and several energy dissipation components are located on the outside of the spiral body. The energy dissipation components are used to absorb impact energy and protect the spiral body.

[0009] The auxiliary installation structure is disposed between the spiral body and the base, and is used to assist in fixing the spiral body to the base.

[0010] Preferably, the storage structure includes partitions, a filling cavity, a feeding port, and a sealing cap. Several partitions are provided and fixed inside the base, forming a filling cavity between them. A feeding port is provided on the side of the filling cavity, and a sealing cap is connected to the outside of the feeding port. By opening the sealing cap, bulk materials or water can be added to the filling cavity through the feeding port, thereby adjusting the counterweight of the base.

[0011] Preferably, the spiral body includes a main pier housing and a spiral structure. The main pier housing is fixed to the base and has a hollow interior. The spiral structure is fixed to the outside of the main pier housing. The main pier housing is the main support for the entire steel structure supported by the pier. Together with the spiral structure, it can effectively decompose and guide the impact force of the ship to the entire structure and then transfer it to the foundation, acting like a natural "force deflector".

[0012] Preferably, the main pier body has a large bottom diameter and a small top diameter, forming a stable conical system. This conical shape results in a very low center of gravity, much like a pyramid, effectively resisting overturning moments. It also absorbs and dissipates energy better than vertical piles.

[0013] Preferably, the spiral structure includes several spiral trusses and node steel. The spiral discs of the spiral trusses are located on the outside of the main hull of the pier, and node steel is fixed between adjacent spiral trusses. The spiral trusses are made of high-strength low-alloy steel, and the node steel is made of weldable structural cast steel. The high-strength low-alloy steel spiral trusses have high strength, high toughness, and are easy to weld. The spiral trusses are connected by weldable structural cast steel node steel, resulting in a free form, smooth force flow, and isotropy. By forming a spiral line from the spiral trusses, the spiral line itself is the most natural force transmission path. When a ship impacts any point on the spiral structure, the impact force will be smoothly guided and dispersed throughout the structure along the curve of the spiral trusses, like water flowing through a whirlpool, and ultimately transmitted to the foundation and seabed. This avoids the "hard-on-hard" stress concentration zone formed below the impact point in traditional vertical piles.

[0014] Preferably, the energy dissipation component includes an energy-absorbing sphere and a hinged sphere. The energy-absorbing sphere is fixed to the hinged sphere and is hinged to the main hull of the ship's pier via the hinged sphere. By setting the energy dissipation component on the outside of the main spiral structure, mimicking the branching structure of coral, when the ship is impacted, the outer "coral" branches will first undergo elastic or controllable plastic deformation, "breaking" like coral to absorb most of the kinetic energy and protect the main structure.

[0015] Preferably, the energy-absorbing sphere comprises a core skeleton, an energy-dissipating filler, and a sacrificial layer. The core skeleton is made of high-strength special steel, including HSLA steel. The energy-dissipating filler is located inside the core skeleton and is made of a high-damping elastic material, including polyurethane elastomer or rubber. The sacrificial layer is located outside the core skeleton and is made of porous, easily deformable weathering steel or special engineering plastic mesh. The core skeleton, as the main load-bearing skeleton, ensures that the unit maintains structural integrity and does not collapse even under large deformations. It mimics the calcium carbonate skeleton of coral. The energy-dissipating filler is the main force for energy absorption. Upon impact, the elastomer undergoes significant compression and shear deformation, converting the ship's kinetic energy into internal energy (thermal energy) and dissipating it. Its function is similar to the cushioning effect of car tires. The sacrificial layer is the first part to come into contact with the ship. Its porous and relatively fragile characteristics allow it to undergo controllable crushing or deformation under low-energy impacts, acting as the first line of defense, sacrificing itself to protect the internal structure. At the same time, its rough and porous surface is a "fully furnished house" customized for marine life.

[0016] Preferably, the auxiliary installation structure includes a mounting base, positioning screws, and a locking nut. The mounting base is fixed to the bottom of the main hull of the ship's pier. Several positioning screws are provided and fixed above the base. The positioning screws pass through the mounting base and are connected to the locking nut. The mounting base is locked and fixed by the locking nut, and the spiral body is connected to the base to facilitate subsequent welding or casting.

[0017] Compared with the prior art, the beneficial effects of the present invention are: This invention, through the layered design of the energy dissipation component "sacrificial layer and energy dissipation filler", can absorb impact kinetic energy of different intensities in stages, significantly reducing the force transmitted to the main structure; the force decomposition effect of the spiral structure avoids structural cracking caused by excessive local stress, while reducing the reaction force during ship collisions and reducing the risk of ship damage.

[0018] The conical pier main hull forms a pyramid-shaped low center of gravity system, effectively resisting overturning moments generated by impacts, and its stability far exceeds that of vertical pile structures; the adjustable storage structure can adjust the counterweight according to actual working conditions to adapt to the stability requirements of different scenarios.

[0024] Please see Figure 1-5 The present invention provides a technical solution: a steel structure berthing pier, including a base 1, a storage structure 2, a spiral body 3, an energy dissipation component 4, and an auxiliary installation structure 5.

[0025] The storage structure 2 is installed on the base 1. The storage structure 2 is used to add bulk materials or water and adjust the counterweight of the base 1.

[0026] The spiral body 3 is positioned above the base 1. The spiral body 3 is used to decompose and guide the impact force of the ship, and to absorb and dissipate energy.

[0027] The energy dissipation component 4 is provided in several parts, and several energy dissipation components 4 are arranged on the outside of the spiral body 3. The energy dissipation components 4 are used to absorb impact energy and protect the spiral body 3.

[0028] The auxiliary installation structure 5 is disposed between the spiral body 3 and the base 1. The auxiliary installation structure 5 is used to assist in fixing the spiral body 3 to the base 1.

[0029] Furthermore, the storage structure 2 includes partitions 201, a filling cavity 202, a feeding port 203, and a sealing cap 204. Several partitions 201 are provided, and these partitions 201 are fixed inside the base 1. The filling cavity 202 is formed between the partitions 201. A feeding port 203 is provided on the side of the filling cavity 202, and a sealing cap 204 is connected to the outside of the feeding port 203. By opening the sealing cap 204, bulk materials or water can be added to the filling cavity 202 through the feeding port 203, thereby adjusting the counterweight of the base 1.

[0030] Furthermore, the spiral body 3 includes a main pier housing 301 and a spiral structure 302. The main pier housing 301 is fixed to the base 1, and the interior of the main pier housing 301 is hollow. The spiral structure 302 is fixed to the outside of the main pier housing 301. The main pier housing 301 is the main support of the entire steel structure relying on the pier. Together with the spiral structure 302, it can effectively decompose and guide the impact force of the ship to the entire structure and then transfer it to the foundation, just like a natural "force guide".

[0031] Furthermore, the main pier body 301 has a large bottom diameter and a small top diameter, forming a stable conical system. This conical shape results in an extremely low center of gravity, much like a pyramid, effectively resisting overturning moments. It absorbs and dissipates energy better than vertical piles.

[0032] Furthermore, the spiral structure 302 includes several spiral trusses 3021 and node steels 3022. The spiral trusses 3021 are spirally arranged on the outside of the main hull 301 of the pier. Node steels 3022 are fixed between adjacent spiral trusses 3021. The spiral trusses 3021 are made of high-strength low-alloy steel, and the node steels 3022 are made of weldable structural cast steel. The high-strength low-alloy steel spiral trusses 3021 have high strength, high toughness, and are easy to weld. The spiral trusses 3021 are connected by the weldable structural cast steel node steels 3022, resulting in a free form, smooth force flow, and isotropy. By forming a spiral line from the spiral trusses 3021, the spiral line itself is the most natural path for force transmission. When a ship impacts any point on the spiral structure 302, the impact force will be smoothly guided and dispersed throughout the structure along the curve of the spiral trusses 3021, like water flowing through a whirlpool, ultimately being transmitted to the foundation and seabed. This avoids the "hard-on-hard" stress concentration zone that traditional vertical piles form below the impact point.

[0033] Furthermore, the energy dissipation component 4 includes an energy-absorbing ball 401 and a hinged ball 402. The energy-absorbing ball 401 is fixed to the hinged ball 402, and the energy-absorbing ball 401 is spherically hinged to the main hull 301 of the ship's pier via the hinged ball 402. By setting the energy dissipation component 4 on the outside of the main spiral structure 302, mimicking the branching structure of coral, when the ship is impacted, the outer "coral" branches will first undergo elastic or controllable plastic deformation, "breaking" like coral to absorb most of the kinetic energy and protect the main structure.

[0034] Furthermore, the energy-absorbing sphere 401 includes a core frame 4011, an energy-dissipating filler, and a sacrificial layer 4013. The core frame 4011 is made of high-strength special steel, including HSLA steel. The energy-dissipating filler is located inside the core frame 4011 and is made of a high-damping elastic material, including polyurethane elastomer or rubber. The sacrificial layer 4013 is located outside the core frame 4011 and is made of porous, easily deformable weathering steel or special engineering plastic mesh. The core frame 4011 serves as the main load-bearing frame, ensuring that the unit maintains structural integrity and does not fall apart during large deformations. It mimics the calcium carbonate skeleton of coral. The energy-dissipating filler 4012 is the main force for energy absorption. Upon impact, the elastomer undergoes huge compression and shear deformation, converting the ship's kinetic energy into internal energy (thermal energy) and dissipating it. Its function is similar to the cushioning of a car tire. The sacrificial layer 4013 is the first part to come into contact with the ship. Its porous and relatively fragile nature allows it to undergo controlled crushing or deformation under low-energy impacts, serving as the first line of defense, sacrificing itself to protect the internal structure. At the same time, its rough and porous surface is a "fully furnished house" custom-designed for marine life.

[0035] Furthermore, the auxiliary installation structure 5 includes a mounting base 501, positioning screws 502, and a locking nut 503. The mounting base 501 is fixed to the bottom of the main hull 301 of the ship pier. Several positioning screws 502 are provided and fixed above the base 1. The positioning screws 502 pass through the mounting base 501 and are connected to the locking nut 503. The mounting base 501 is locked and fixed by the locking nut 503, and the spiral body 3 is connected to the base 1 to facilitate subsequent welding or casting.

[0036] In summary, during use, the energy dissipation component 4 is the first to contact and absorb energy, reducing the initial kinetic energy of the impact. During a ship collision, the outermost energy dissipation component 4 is the first to come into contact. The sacrificial layer 4013 of the energy dissipation component 4 undergoes controlled crushing deformation first, absorbing low-energy impacts. If the impact force is large, the energy dissipation filler converts kinetic energy into heat energy dissipation through compression and shear deformation. The core frame 4011 (HSLA steel) ensures that the energy dissipation component 4 does not fall apart during deformation, preventing debris from affecting the structure and achieving the function of the "first line of defense against energy absorption".

[0037] The spiral body 3 decomposes the force to avoid stress concentration. The impact force that is not fully absorbed is transmitted to the spiral body 3. The spiral structure 302 guides the impact force along the curve to the entire structure through the spiral shape, rather than concentrating it at the point of impact, like a "force guide", avoiding the "hard-on-hard" stress concentration of traditional vertical piles. The conical pier main box 301 (thick at the bottom and thin at the top) uses the low center of gravity to stably transmit the guided force to the base 1, while resisting the overturning moment and preventing the structure from collapsing.

[0038] The base 1 provides stable load bearing, and the auxiliary installation structure 5 ensures overall stability. The force transmitted to the base 1 is ultimately transmitted to the foundation (seabed) through the base 1. The storage structure 2 can adjust the counterweight of the base 1 by adding bulk materials or water to further improve the stability of the base 1 and ensure that the structure does not shift during the force transmission process. The auxiliary installation structure 5 ensures the connection between the spiral body 3 and the base 1 by locking and fixing, and avoids structural loosening during the force transmission process.

[0039] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
