Description
Technical field
The present invention relates to highway crash technical field, in particular to a kind of highway ramp fork anticollision device, collision-prevention device.
Background technique
With flourishing for transportation and economic construction, largely building for highway is continuous with the quantity of vehicle
Increase, and due to a variety of causes of driver, in ring road mouth due to absent minded etc., there are lucky by some drivers
The factors such as good fortune psychology, driver drive the thing that vehicle took a sudden turn and caused Vehicular impact ring road branch road mouth protecting device in ring road mouth
Therefore it is also being continuously increased.Vehicle impact protective device not only easily causes the tragedies such as car crash, but also reduces to a certain extent
Bearing capacity and durability of the highway structure in phase projected life, the protective device due to caused by colliding move past greatly, understand directly
Safety and the durability for influencing highway, even cause the entirety of protective device to fall off when serious.Therefore it designs a kind of novel
Expressway ramp fork anticollision device, collision-prevention device becomes particularly important.
Currently, common processing method is the placement plastics at ring road fork for the safeguard structure at highway ramp fork
Anti-collision barrel or glass fiber reinforced plastics anti-collision bucket, the injury to occupant and the damage to highway facilities, Yi Jizhi when reducing collision
It connects using the clump at ring road fork, to make simple anticollision device, collision-prevention device.But use common plastic/glass steel Anti-collision barrel
When have following problems: 1, be easy to scratch automobile when automobile minor impact, 2, the lighter weight of plastics Anti-collision barrel face oversize vehicle
Not can be well protected driving vehicle and personnel when impact, 3, glass fiber reinforced plastics anti-collision bucket be crushed once be knocked, easily to vehicle
And driver causes secondary injury, 4, glass Anti-collision barrel the disadvantages of cannot being recycled, causing the waste of resource.
Summary of the invention
The present invention in view of the drawbacks of the prior art, provides a kind of highway ramp fork anticollision device, collision-prevention device, can reduce shock
When the impact force born of protective fence, reduce injury to protective fence and driving people itself.
In order to realize the above goal of the invention, the technical solution adopted by the present invention is as follows:
A kind of highway ramp fork anticollision device, collision-prevention device, comprising: Anti-collision barrel 1 and bumping post；
Bumping post is made of inner layer steel plate 2, energy dissipating layer 3, foam concrete structure sheaf 4 and outer layer plate 6；
The inner layer steel plate 2 is circular tube shaped, pours into foam concrete and forms foam concrete structure sheaf 4, the outer side wall of steel plate 2
Around a circle energy dissipating layer 3, outer layer plate 6 is round tube dress, and 3 lateral surface of energy dissipating layer is wrapped up by outer layer plate 6.
The Anti-collision barrel 1 is hollow cylindrical body, and upper surface is provided with the hole for bumping post insertion, 1 upper surface of Anti-collision barrel
Edge is equipped with water filling port 5, for toward injecting liquid inside Anti-collision barrel 1.
Further, the energy dissipating layer 3 is arranged side by side by several broken line type structures 7 and is formed.Broken line type structure 7 includes several
Paper folding type structural unit 8,8 shape of paper folding type structural unit is the pitched roof shape that longitudal section is isosceles triangle, several
The one broken line type structure 7 of formation from beginning to end each other of paper folding type structural unit 8, the adjacent mutual folding of two paper mold structural unit 8
30 ° to 45 ° of line angle degree.
Further, the 6 outer surface spray polyurea material of outer layer plate.
Compared with the prior art, the advantages of the present invention are as follows:
After anticollision device, collision-prevention device is hit, the liquid anticollision layer of Anti-collision barrel absorbs first and dissipative part kinetic energy, remainder
Point kinetic energy be transmitted to internal energy dissipating layer, the last foam concrete structure sheaf for being transmitted to core part again absorb again with
Thus dissipative part kinetic energy reduces the destruction that Vehicular impact Shi Dui highway generates, also can largely protect interior drive
The person of sailing prevents secondary injury.Outer surface of steel tube spray polyurea material outside origami structure makes the anti-of entire energy dissipating layer
Rotten durability is greatly improved, simultaneously because the good shock resistance of polyurea materials also largely increases and disappears
The ductility of ergosphere.Finally due to anticollision layer use foam concrete have the characteristics that it is easy to process so that foam concrete is not
But various products can be produced into factory, and can also site operation.Substantially reduce the duration.
