Pier floating type composite anti-collision jacket

Abstract

The present invention discloses a pier floating type composite anti-collision jacket. The jacket comprises a jacket casing. The jacket casing is made from water-proof hard composite materials. Cylindrical buffering bodies made by bundling rubber steel rings in parallel are arranged in the jacket along the longitudinal direction of the jacket, the cylindrical buffering bodies come into contact with each other, the jacket casing is filled up with the cylindrical buffering bodies, and plastic foaming bodies are also filled in the jacket. The present invention having the advantages of high integral strength, good flexibility, strong deformation capability and good elasticity can automatically change protection height with the variation of the horizontal level, and can protect piers at any time. Besides, impact can be thoroughly buffered during external impact, since the jacket has good energy absorption effect. The impact action time is delayed, and the impact peak value is reduced, so the pier is better protected. After water enters the broken casing, the anti-collision jacket can still float with the height variation of the water surface and continuously performs a protection function. Both the composite materials and the plastic foaming bodies are environmental protection materials. In particular, the rubber steel rings are made from waste materials, so the cost is saved.

Description

technical field [0001] The invention relates to a bridge safety component, in particular to a bridge pier floating composite material anti-collision casing. Background technique [0002] The anti-collision measures of bridge piers are an important means to ensure the safety of bridges, and the main danger comes from ships colliding with bridge piers. The anti-collision measures for bridge piers are to prevent ships from damaging the piers. They mainly include directly connected anti-collision devices and indirect anti-collision devices. Anti-collision problem, but it occupies a large area, so it can only be installed in the river bed with shallow water depth and good foundation.

Problems solved by technology

The anti-collision measures for bridge piers are to prevent ships from damaging the piers. They mainly include directly connected anti-collision devices and indirect anti-collision devices. Anti-collision problem, but it occupies a large area, so it can only be installed in the river bed with shallow water depth and good foundation. It is not suitable for use in waters with small river area. At the same time, the construction cost is high; the directly connected anti-collision device is installed directly To protect the pier on the pier, including elastic deformation structure, plastic deformation buffer structure, etc., it is generally used to fix elastic or plastic deformation devices around the pier, absorb energy through elastic deformation and plastic deformation, and resist the impact force on the pier

[0003] In the prior art, the directly connected anti-collision device generally adopts the anti-collision box structure; the anti-collision box is a facility that is placed outside the pier along the circumference to protect the pier through deformation or damage, including anti-collision shells, anti-collision shells Supports are set inside to resist external impact; in order to ensure that the anti-collision box has a certain strength to ensure the safety of the pier, it is generally made of high-density materials (generally steel structures are easy to rust in water), and the maintenance cost is high. ; and most of them are fixed on the pier. When the water surface changes, the height of the anti-collision box does not change, which cannot play a good anti-collision effect

At the same time, the existing anti-collision sleeves generally use their own damage to achieve the purpose of protecting the bridge pier. The buffering effect of the impact force is poor, and part of the impact force is transmitted to the pier. The anti-collision effect is not ideal.

[0004] In order to solve the above problems, a floating anti-collision box made of glass fiber appeared. Although this glass fiber can float with the height of the liquid level, the anti-collision effect is poor, and the plastic and elastic deformation is poor, and the force is directly transmitted to the pier

At the same time, this kind of anti-collision box will sink after being damaged and enter water, losing the anti-collision protection function
