Abstract

The utility model provides an anti-collision energy dissipating device used for bridge piers and docks, which belongs to sea channel building safety facilities. The anti-collision energy dissipating device comprises unit energy dissipating bodies and is characterized in that the unit energy dissipating body comprises an external coating plate beam structure and an internal buffering energy absorbing damping unit, wherein the external coating plate beam structure and the internal buffering energy absorbing damping unit are singly or separately arranged on the external sides of the bridge pier, the dock and an anti-collision device in a combined way; the unit energy dissipating bodies not only can be singly used for collision prevention of low-grade sea channel pier and the mooring of the dock but also can be arranged on the external side of the anti-collision device in a combined way to be used for high-grade sea channels; by using anti-collision energy dissipating device, partial collision energy can be absorbed by the deformations of the buffering energy absorbing damping element and the external plate beam structure of the unit energy dissipating body, and the bow of the ship can be shifted by the deformations to change the moving direction of the ship; therefore, serious collision accidents caused by direct collision of the protective facility from the ship can be effectively avoided, the safety is enhanced and the anti-collision energy absorbing effect of the anti-collision device is improved to further improve the anti-collision effect.

Description

A kind of anti-energy dissipator that hits that is used for bridge pier and harbour dock

Technical field

A kind of anti-energy dissipator that hits that is used for bridge pier and harbour dock of the utility model belongs to navigation channel building safety facility, particularly bridge pier, harbour dock.

Background technology

Along with the World Economics develop rapidly; The ship development is maked rapid progress, and river Hainan Airlines freight volume is increasing, and the contradiction of shipping and aquatic building thing manifests day by day; As: waterway classification improves; The bridge design ship hits that the power value is less than normal, the lifting of the tonnage of ship and the speed of a ship or plane, and a large amount of constructions of river sea-bridge beam make that the possibility of ship collision bridge is increasing.But the anti-energy dissipating ability of hitting of present domestic anticollision device, collision-prevention device is very limited, and the utility model removes and independently applies to the bridge pier outside, inferior grade navigation channel and harbour dock, also can cooperate anticollision device, collision-prevention device to apply to pier anticollision, improves the anti-energy dissipating ability of hitting of anticollision device, collision-prevention device self.

The utility model content

The purpose of the utility model provides a kind of anti-energy dissipator that hits that is used for bridge pier and harbour dock, to strengthen the energy dissipating impact resistance of bridge pier, harbour dock and anticollision device, collision-prevention device thereof, the safety of better protection shipping building and delivery boats and ships.

The utility model purpose realizes through following technical scheme:

The utility model is anti-to hit energy dissipator, is made up of the unit damping body, and characteristics are that the unit damping body is made up of outer wrap slab and girder and internal damping energy-absorbing damping element, makes up the outside that is arranged on bridge pier, harbour dock and anticollision device, collision-prevention device thereof separately or at interval.

The utility model is anti-to be hit the distortion of energy dissipator through the numerous buffering energy-absorbing damping elements in its unit damping body and has prolonged collision time and absorbed the part collision energy; The slab and girder of outer wrap then can let numerous buffering energy-absorbing damping elements become as a whole stressed; Slab and girder structure of this outside parcel not only can the absorption portion collision energy; Its distortion can also be stirred the direction of motion that fore changes boats and ships; Let boats and ships self take away a large amount of kinetic energy and reduce energy exchange, the direct bump that therefore can effectively avoid protecting facility to receive boats and ships causes the seriously generation of bump accident, strengthens safety.What boats and ships at first touched is this utility model; The utility model manufacturing is simple; Transportation, installation, maintenance are convenient, not only can strengthen the whole stressed of buffering energy-absorbing damping element, can also when structural failure, implement the partly replacing of impaired unit damping body easily.

The utility model is the alongside that unit piece not only can independently apply to crashproof, the harbour dock of inferior grade navigation channel bridge pier; Also can make up the outside that is arranged on anticollision device, collision-prevention device and apply to high-grade navigation channel; Increase the anti-energy-absorbing function that hits of anticollision device, collision-prevention device, with the anti-effect of hitting of further reinforcement.

The specific embodiment

How combine accompanying drawing to further specify the utility model with the utilization instance implements at present:

The utility model is anti-to hit energy dissipator, is constituted by the unit damping body, and the unit damping body is made up of outer wrap slab and girder 1 and internal damping energy-absorbing damping element 2, is arranged on the outside of bridge pier, harbour dock and anticollision device, collision-prevention device thereof at interval, fixes with securing member.

The utility model buffering energy-absorbing damping element 2 can be that rubber or steel protect string; Also can be that perhaps some other has the element of buffering energy-absorbing function to steel wire coil; The slab and girder 1 of its outer wrap can be a steel plate structure, also can be that engineering constitutes with macromolecular material.This energy dissipator installation steps are following:

It is following that example 1 applies to low waterway classification navigation channel pier anticollision installation steps:

1), pre-buried fixture 5 is positioned on the steel form of cushion cap, bridge pier 7, matches with cushion cap, concrete the building of bridge pier by the requirement of design drawing relative dimensions;

2), wait to build the back that finishes buffering energy-absorbing damping element 2 be installed, successively buffering energy-absorbing damping element 2 is installed;

3), slab and girder 1 and buffering energy-absorbing damping element 2 are located with anchor bolt 4.Referring to Fig. 1.

Example 2 the utility model cooperate anticollision device of pier, and the installation steps that apply to the anticollision device, collision-prevention device outside are following:

1), puts the hole in the anticollision device, collision-prevention device outside 6 by the requirement of design drawing relative dimensions;

2), buffering energy-absorbing damping element 2 is positioned at the anticollision device, collision-prevention device outside with anchor bolt 4;

3), slab and girder 1 and buffering energy-absorbing damping element 2 are located with anchor bolt 4.Referring to Fig. 2.

Claims

1. anti-energy dissipator that hits that is used for bridge pier and harbour dock; Constitute by the unit damping body; It is characterized in that the unit damping body is made up of outer wrap slab and girder and internal damping energy-absorbing damping element, separately or at interval combination is arranged on the outside of bridge pier, harbour dock and anticollision device, collision-prevention device thereof.
