Specific implementation mode
The embodiment of technical solutions of the utility model is described in detail below in conjunction with attached drawing.Following embodiment is only For clearly illustrating the technical solution of the utility model, therefore it is only used as example, and this practicality cannot be limited with this Novel protection domain.
As shown in Figures 1 to 4, the modularization anticollision device of pier 100 of multilayered structure provided in this embodiment, including it is multiple It can be spliced into the anticollision segment 1 of cricoid arc from beginning to end, the inner surface of the anticollision segment 1 is close to the setting of bridge pier 200, referring to Fig. 3, Each anticollision segment 1 is at least divided into three layers from inside to outside, and elastic endergonic element 11 is evenly arranged in every layer of anticollision segment 1. The preferably fibre-reinforced composite material of the material of anticollision segment 1, light weight, intensity is big, transports and easy for installation.Referring to Fig. 2, originally In embodiment, the anticollision device, collision-prevention device 100 of a complete cyclic structure is divided into four anticollision segments 1, each anticollision segment 1 can be It is produced as an one integral piece in factory, Tenon is respectively arranged in the both sides of anticollision segment 1, and then quick, letter can be realized by Tenon Single assembled connection;Each anticollision segment 1 is equidistantly divided into three layers, and structure is uniform, and production is simple.And in the appearance of anticollision segment 1 Face is coated with warning color, to play the role of traffic alarm.
Referring to Fig. 4, the elastic endergonic element 11 in the present embodiment is made of elastic rubber material, and shape is in drum type, And two planar ends are both provided with the ring-shaped step 111 outwardly protruded, and connecting hole 112 is provided on ring-shaped step 111.System When making, two planar ends of drum type are connected respectively on the layer wall of the anticollision segment 1 of one layer of correspondence, by connecting hole 112, can be incited somebody to action Elastic endergonic element 11 is easily fixed by connectors such as connecting pin, screws.Elastic endergonic member 11 in each layer anticollision segment 1 Part shifts to install, and is more advantageous to and disperses the impact force of vehicle, and the abatement effect of power is more preferable.
Above-mentioned anticollision device, collision-prevention device 100 is connected by simple assembled at the scene, can form circular bridge pier 200 1 weeks Cyclic structure.According to the range of height and protection that bridge pier 200 needs to protect, above-mentioned assembled cyclic structure can be The upper and lower of bridge pier 200 sets up one layer or multilayer, realizes flexible combination, flexibility is strong, and applicability is wide.
Composite material, high elastic rubber material are combined by above-mentioned anticollision device, collision-prevention device 100, first cutting according to bridge pier 200 Face size arranges that the body structure of composite material, casing are equidistantly divided into three layers along circular arc, high in every layer of internal spaced set Elastic gum power-absorbing 11 made of elastic rubber sprays warning color in outermost, and an anticollision segment 1 is integrally formed.It is anti- It hits segment 1 and arranges that quantity can be according to protection height and protective range flexible combination.Factory modularization makes, and installation is rapid, convenient, And it is anti-aging, high temperature resistance is good.
Above-mentioned anticollision device, collision-prevention device 100 can push headstock aside when low-angle is hit, so that most of kinetic energy is retained in vehicle On, and as vehicle braking dissipates;When wide-angle is collided the outer layer of the anticollision segment 1 of composite material casing structure first with vehicle Head contact, impact force moment reach peak value, and the shell of composite material casing is crushed after consuming sub-fraction Impact energy, outside The elastic gum power-absorbing 11 of layer absorbs part Impact energy by itself large deformation, cuts down impact force;The subsequent second layer is compound Material participates in stress, and impact force reaches second peak value, and second layer elastic gum power-absorbing 11 starts energy-absorbing, and impact force is further It is cut in;Last third layer composite material is started to work, and impact force reaches after third peak value again by elastic gum power-absorbing 11 reductions, Impact energy are significantly absorbed, and classification energy consumption is effectively protected bridge pier, reduces the possibility of injury to personnel.
In conclusion the modularization anticollision device of pier of the multilayered structure using above-mentioned technical proposal, is spelled using modularization Assembling structure, convenient for batch production, and on-site consolidation is convenient, there is larger popularizing application prospect;Simultaneously using the side of classification energy consumption Formula effectively cuts down the impact force that Vehicular impact is brought, protects bridge pier and personnel safety.
