Specific embodiment
It is described in detail below in conjunction with embodiment of the attached drawing to technical solutions of the utility model.Following embodiment is only
For clearly illustrating the technical solution of the utility model, therefore it is only used as example, and it is originally practical to cannot be used as a limitation limitation
Novel protection scope.
As shown in Figures 1 to 4, layering energy-absorption type modularization pier anti-collision device 100 provided in this embodiment uses
When be wrapped in bridge pier 200 setting, specific structure includes at least two anticollision segments 10 that can be spliced into cricoid arc from beginning to end, such as
Shown in Fig. 2, the anti-vehicle collision device 100 of a complete cyclic structure is divided into four anticollision segments 10 in the present embodiment, it is raw
It produces simply, on-site consolidation also facilitates.Anticollision segment 10 includes interior buffer layer 1,2 and of middle buffer layer of concentric setting from inside to outside
Outer buffer layer 3, interior buffer layer 1 and middle buffer layer 2 are hollow box body structure, material it is preferable to use fibre-reinforced composite material,
Light weight, intensity is big, and transport and installation are convenient.Multiple elastic damping elements 4, middle buffering have been evenly arranged in interior buffer layer 1
Honeycomb buffer element 5 is filled in layer 2, outer buffer layer 3 is made of corrosion-resistant steel material, and in the outer of outer buffer layer 3
Surface is coated with warning color.
Referring to fig. 4, elastic damping element 4 is made of elastomeric rubber, and cross section is V-shaped, and the opening one of V-type
Side is arranged to middle buffer layer 2；And outwardly extending fixed-wing 41, fixed-wing are set in the V-type open end of elastic damping element 4
It is provided with connecting hole 42 on 41, by connecting hole 42, elastic damping element 4 can easily be passed through the connection such as connecting pin, screw
Part is fixed in interior buffer layer 1.
Each anticollision segment 10 can be in factory as an one integral piece production, and Tenon is respectively arranged in the two sides of anticollision segment 10, into
And quick, simple assembled connection can be realized by Tenon, it is formed around 200 1 weeks cyclic structures of bridge pier.According to bridge pier
The range of 200 height and protection for needing to protect, above-mentioned assembled cyclic structure can be in the up and down direction of bridge pier 200
Upper setting one layer or multilayer, realization flexible combination, strong flexibility, applicability are wide.
Above-mentioned anti-vehicle collision device 100 is, it can be achieved that factory modularization makes, and on-site consolidation, it is rapid, convenient to install, anti-ageing
Change, high temperature resistance are good.Headstock can be pushed aside when low-angle is hit, so that most of kinetic energy retains onboard, and with
Vehicle braking dissipates；In wide-angle collision, the outer buffer layer 3 of the steel of outer layer is contacted with headstock first, due to the two rigidity phase
When impact force moment reaches peak value, and steel plate is crushed after consuming sub-fraction Impact energy, and middle buffer layer 2 is started to work, case
While the middle buffer layer 2 of body structure consumes most of Impact energy, impact force is significantly cut down, is subsequently placed at interior buffering
Elastic damping element 4 in layer 1, dissipates remaining energy using the flexible deformation of itself, thus effective protection bridge pier 200.
Each layer classification energy-absorbing, energy consumption, couple hardness with softness, and energy collective effect resists impact force caused by automobile impacting, can protect bridge pier simultaneously
200 with vehicle on personnel safety, have biggish popularization and application foreground.
