Description
Technical field
The present invention relates to a kind of bridge anti-collision device, especially relate to a kind of composite material and building rubber compound formula box bridge anticollision device, collision-prevention device.
Background technology
Along with the development of China's economy, society, culture, the interchange of nationwide economic civilization, the development of transport service has become the huge motive force of China's economic development.Road, bridge, harbour, harbour etc. are increasing, the vehicles increasing, and trend towards maximizing, and conflicting between the vehicles with means of transportation is increasingly serious.Ship car-bridge collision accident is increasing, causes the massive losses of lives and properties, traffic congestion, pollution of water resource etc.Bridge-collision-avoidance problem more and more obtains the concern of government and academia, how to prevent or reduce the research topic that ship car-bridge collision accident has become current.
In order to the serious consequence preventing or reduce ship car shock Bridge Accidents to cause, be studied anticollision device, collision-prevention device both at home and abroad, and be applied to the of a great variety of actual anticollision device, collision-prevention device at present, each anticollision device, collision-prevention device has the respective scope of application.The method of anticollision device, collision-prevention device classification is a lot, can simply be divided into indirect-type and Direct-type generally.Indirect-type is that power is delivered to ground by anticollision device, collision-prevention device or other bear in the structure of impact, as: multi-column pier foundation, manually builds island, artificial cofferdam etc.This anticollision device, collision-prevention device anti-collision effect is better, but needs to take certain river course due to indirect type anticollision device, collision-prevention device, and the impact for river is comparatively large, and cost is higher usually.Direct-type anticollision device, collision-prevention device mainly weakens the power be delivered on bridge pier by the power consumption of self, thus reduces the effect of clashing into, and this anticollision device, collision-prevention device has fender mode, rope mode of texturing, fixing or buoyancy anticollision device etc.This anticollision device, collision-prevention device is relatively little on the impact in river course, and the impact simultaneously by the depth of water is little, and construction costs is lower, and engineering quantity is less, is more and more widely used.Direct-type anticollision device, collision-prevention device weakens the effect of shock mainly through self flexibility and energy dissipation capacity, if anticollision device, collision-prevention device is too flexible, when after hull contact anticollision device, collision-prevention device, the distortion of the anticollision device, collision-prevention device overwhelming majority occurs in the position of contact, and other parts of anticollision device, collision-prevention device do not have too many crashproof effect.
If and anticollision device, collision-prevention device too rigidity, then cannot play energy dissipating well, such as Chinese patent CN103911943 A discloses a kind of anticollision device, collision-prevention device of bridge pier, specifically comprise: composite material fixed bed and anticollision barrier, composite material fixed bed fixed packet is overlying on the bridge pier external surface above the water surface, the external surface of composite material fixed bed offers the hole of outwardly convex, two ports of anticollision barrier are bolted, fixedly be plugged in two circular cavities, two circular cavities fixed support anticollision barrier, from the bottom of hole to the port of anticollision barrier, radial direction is fixedly installed some waddys successively.Composite material fixed bed and anticollision barrier, adopt glass fibre reinforced composion to make, matrix material is unsaturated-resin or vinylite; Reinforcing material is glass fiber or carbon fiber.But the anticollision device, collision-prevention device of this bridge pier is mainly undertaken crashproof by the composite material that rigidity is larger, on the one hand, although it can protect bridge pier, it does not have good energy dissipating effect, has larger damage to bridge, boats and ships etc.; On the other hand, it is textural cumbersome, and each anticollision barrier needs meticulous layout, and the intensity of intensity under ship shock effect that anticollision barrier and bolt etc. connect can not ensure.In addition, waddy ducks in drink for a long time and easily rots, and when bolt continuous damage, waddy does not just have substitution effect yet.
