The box body connecting portion 12 is a bracket. The design of the wave unloading through hole weakens the impact force of water flow, avoids the whole transitional vibration of the assembled anti-collision facility, and ensures that the assembled anti-collision facility has good stress performance under the wave action.

In a specific embodiment, the high molecular damping energy dissipation material is polyurethane foam. Polyurethane foam is commercially available.
In a specific embodiment, the outer side surface of the anti-collision floating box body 11, which is close to the pier, is further provided with a polymer damping element 15, the polymer damping element 15 is a rubber block with a built-in steel wire mesh, the polymer damping element 15 is provided with a countersunk through hole, and the polymer damping element 15 is detachably arranged on the outer side surface of the anti-collision floating box body 11, which is close to the pier, through the countersunk through hole by a bolt. The high polymer damping element 15 can slow down the impact force through the elastic deformation, prolongs the impact force time course and reduces the acting force peak value on the bridge pier.
In a specific embodiment, the top of the anti-collision buoyancy tank 11 is provided with a manhole, and a detachable access cover 111 is provided at the manhole.
In one placeIn a specific embodiment, the concrete adopted by the anti-collision buoyancy tank 11 is ultra-high performance concrete, the ultra-high performance concrete comprises cement, silica fume, fly ash, quartz powder, quartz sand, nano mineral powder, polycarboxylic acid high efficiency water reducer, water and steel fiber, and the nano mineral powder comprises nano SiO 2 And nano CaCO 3 The ultra-high performance concrete has compressive strength of 120 MPa-200 MPa and material breaking energy of 20-40 kJ/m 2 The diffusion rate of chloride ions is 0.02X10 -12 m 2 /s～0.03×10 -12 m 2 And/s and the water absorption porosity is 1 to 1.5 percent. Ultra-high performance concrete is commercially available.
In a specific embodiment, the fabricated anti-collision facility for the water area pier comprises four anti-collision floating boxes 1, wherein the four anti-collision floating boxes 1 are sequentially connected to form an ellipse, two anti-collision floating box bodies 11 are in a cuboid shape, and the other two anti-collision floating box bodies 11 are in a semicircular shape.
When the ship collides with the anti-collision device, under the condition that the ship speed is low, when the ship contacts with the high polymer collision steering device 16, the ship can be guided to steer, so that most of kinetic energy of the ship is reserved on the ship, the energy conversion in the collision process is reduced, the collision energy born by the bridge is reduced, and the bridge and the ship are protected. Under the condition of higher ship speed, the high polymer collision steering device 16 and the armored paint on the surface of the buoyancy tank body also play a role in buffering and guiding, then the ship collides with the ultra-high performance concrete material on the buoyancy tank surface, the material deforms or breaks and absorbs energy, when the ship collision force reaches the inside of the buoyancy tank body, the internal energy dissipation device 14 of the ship can plastically deform and consume the collision energy, and meanwhile, the polyurethane foam high polymer material in the internal energy dissipation device 14 also can compress and deform and consume energy. The buoyancy tank body is buffered by the high polymer damping element 15 and contacted with the bridge pier, and finally the impact force reaching the bridge pier is insufficient to damage the bridge pier, and meanwhile, the reaction force suffered by the ship is consumed mostly by the energy consumption device in the buoyancy tank body, so that the semi-rigid and semi-flexible anti-collision device can protect the safety of the bridge pier and the ship under the action of the energy consumption system.
The internal energy dissipation device 14 of the box is one of the most important energy dissipation elements, and mainly plays a role in diffusing impact force and reducing local node damage.
The wave unloading through hole design between two anti-collision floating box bodies can weaken the fluid impact force born by the assembly type anti-collision facility for the water area bridge pier to a certain extent, meanwhile, the contact area of the side wall of the anti-collision floating box body is reduced, the transmission of the impact energy between the anti-collision floating box bodies is also greatly weakened, and the effect of blocking the expansion of the damage area is achieved. Because the connecting pin shaft 2 at the connecting part of the box body connecting part 12 is movable, the anti-collision floating box body and the box body are mutually movable, so that when sea waves or foreign matters strike the anti-collision floating box body, the anti-collision floating box body and the box body can mutually move to carry out torsion energy consumption.
When the impact force of the ship is small, the high polymer collision steering device 16 is easy to deflect the ship, the anti-collision buoyancy tank body of the internal energy consumption device 14 releases the impact capability through structural deformation, and the ship is easy to deflect due to small friction force of the armor coating.
When the impact force of the ship is large, the anti-collision buoyancy tank body with the built-in internal energy consumption device 14 can release the impact energy of the ship through the deformation and damage of the structure, so that the impact force peak value is reduced, and the bridge pier and the ship are protected from damage. Even if the anti-collision floating box body is impacted and damaged, water flows into the anti-collision floating box body, the built-in polyurethane foam rubber can exert the floating force to prevent the anti-collision floating box body from sinking into water.
The invention releases energy through the deformation and damage of the anti-collision buoyancy tank body, the deformation of the high polymer collision steering device and the high polymer damping element, and the like, thereby protecting the bridge pier and the ship from being damaged.
The invention has better structural reliability. The invention adopts the ultra-high performance concrete as the main material, and has outstanding innovation. The ultra-high performance concrete has high impact toughness, high impermeability and excellent durability, and can absorb the impact capacity of the ship part through deformation and damage of the ultra-high performance concrete structure, reduce the impact peak value and have high energy absorption capacity. Meanwhile, the invention adopts the armor coating to buffer the impact force, changes the course after the ship is impacted, and reduces the collision energy of the ship. The invention can effectively disperse impact load, protect bridges and ships, and take into account the interests of several related parties.
The invention has better environmental adaptability. The main body material ultra-high performance concrete of the anti-collision floating box body has excellent compactness, impermeability and durability, and has good waterproof capability and seawater corrosion resistance. The armor coating on the collision surface of the anti-collision buoyancy tank can also improve the seawater permeation resistance of the structure.
The invention has better construction feasibility and economy. Compared with inland, the invention has the advantages that the construction of the offshore bridge is more difficult, the invention adopts a modular structure and industrial manufacture, the ship can be quickly repaired after collision, the small collision is not damaged, the middle collision is well repaired, and the large collision is well replaced. The installation, transportation, maintenance and replacement are convenient, and the installation and construction are convenient.
The foregoing is a further detailed description of the invention in connection with specific preferred embodiments, and it is not to be construed that the invention is limited to the specific embodiments. It will be apparent to those skilled in the art that several simple deductions and substitutions can be made without departing from the spirit of the invention, and these are considered to be within the scope of the invention.
