The vehicle impact protection device not only easily causes tragedies such as vehicle destruction and death, but also reduces the bearing capacity and durability of a highway structure in the design life to a certain extent, and the safety and durability of the highway can be directly influenced due to the excessive movement of the protection device caused by collision, and even the whole protection device falls off in serious cases. Therefore, it becomes very important to design a novel expressway ramp turnout anti-collision device.
At present, for a protection structure of a ramp turnout of a road, a common treatment method is to place a plastic anti-collision barrel or a glass reinforced plastic anti-collision barrel at the ramp turnout to reduce the injury to people in a vehicle and the damage to road facilities during collision, and directly use a cement pier at the ramp turnout to make a simple anti-collision device. However, the following problems are encountered when using the conventional plastic/glass fiber reinforced plastic crash barrel: 1. the automobile is easy to scratch when the automobile is slightly impacted, 2, the plastic anti-collision barrel is light in weight, the running vehicle and personnel cannot be well protected when a large-sized vehicle is impacted, 3, the glass fiber reinforced plastic anti-collision barrel is broken once being impacted, secondary damage is easy to cause to the vehicle and a driver, and 4, the glass anti-collision barrel cannot be recycled, so that the resource waste is caused.
SUMMERY OF THE UTILITY MODEL
The utility model discloses to prior art's defect, provide a highway circle turn road fork buffer stop, the impact that the rail guard bore when can reducing the striking reduces the injury to rail guard and driving person self.
In order to realize the purpose of the utility model, the utility model discloses the technical scheme who takes as follows:
a road ramp turnout collision avoidance device, comprising: the anti-collision barrel 1 and the anti-collision column;

Further, the energy dissipation layer 3 is formed by arranging a plurality of broken line type structures 7 side by side. The fold line type structure 7 comprises a plurality of paper folding type structure units 8, one paper folding type structure unit 8 is in an inclined roof shape with the longitudinal section being an isosceles triangle, the plurality of paper folding type structure units 8 are mutually connected end to form a fold line type structure 7, and the fold line angle of every two adjacent paper folding type structure units 8 is 30-45 degrees.
Further, the outer surface of the outer steel plate 6 is sprayed with polyurea material.
Compared with the prior art, the utility model has the advantages of:
after the anti-collision device is impacted, the liquid anti-collision layer of the anti-collision barrel firstly absorbs and dissipates part of kinetic energy, the rest part of kinetic energy is transmitted to the internal energy dissipation layer, and the last foam concrete structure layer transmitted to the core part again absorbs and dissipates part of kinetic energy, so that the damage to a road during vehicle impact is reduced, a driver in the vehicle can be protected to a great extent, and secondary damage is prevented. The outer surface of the steel pipe outside the paper folding structure is sprayed with the polyurea material, so that the corrosion resistance and durability of the whole energy dissipation layer are greatly improved, and meanwhile, the ductility of the energy dissipation layer is greatly increased due to the good impact resistance of the polyurea material. Finally, as the foam concrete adopted by the anti-collision layer has the characteristic of convenient processing, the foam concrete not only can be produced into various products in a factory, but also can be constructed on site. The construction period is greatly shortened.
