Technical Field
[0001] The utility model relates to the field of highway traffic safety facility engineering, in particular to an anti-collision guardrail for highway traffic safety facility engineering. Background Art
[0002] Traffic safety projects can also be called traffic safety facilities projects or traffic projects and facilities projects along the route. The construction scale and standards are determined according to the highway network planning, highway functions, grades, traffic volume, etc., and are designed in accordance with the principle of "ensuring safety, providing services, and facilitating management". There are three types of traffic safety facilities, service facilities, and management facilities. The grades and scope of application are divided into four levels: A, B, C, and D. Highway traffic safety facilities projects refer to the general term for pedestrian tunnels, pedestrian overpasses, lighting equipment, guardrails, signs and markings and other facilities set up along the roads to ensure the safety of vehicles and pedestrians and give full play to the role of roads. Anti-collision guardrails are one of them. Anti-collision guardrails are facilities installed on roads or other surrounding environments to prevent vehicles or personnel from colliding, thereby ensuring the safety of life and property. They have different types and application scenarios.
[0003] After searching, the publication number is a highway anti-collision guardrail, which specifically discloses a highway anti-collision guardrail, including a base plate, a first side plate fixedly installed on one side of the upper surface of the base plate, and a second side plate fixedly installed on the other side of the upper surface of the base plate, cross bars fixedly installed between the upper and lower ends of the first side plate and the second side plate, and a plurality of baffle bars fixedly installed equidistantly between the two cross bars, and a positioning assembly is arranged on the first side plate, and the positioning block is arranged inside the positioning groove through the positioning assembly. The utility model arranges the positioning block inside the positioning groove, and at this time, the guide plate is moved so that one end of the fixing column is passed through the through hole and arranged inside the positioning hole, and the bolt is rotated so that one end of the bolt is arranged inside the bolt hole. At this time, the guide plate can be fixed to the side of the first side plate to connect the two guardrails together. The process of connecting the guardrails together by this device is simple, and the stability is good, and there will be no falling off.
[0004] During the use of existing anti-collision guardrails, since the function of the anti-collision guardrail itself is to reduce the damage to the vehicle and the driver inside when the vehicle collides, and only relies on the rigidity of the material of the anti-collision guardrail itself to mitigate the impact force of the vehicle after the collision, this will still bring a high risk to the driver. In addition, no other anti-collision measures are set in the above-mentioned comparative case. Therefore, when the anti-collision guardrail is impacted, not only is the anti-collision guardrail itself seriously damaged, but the broken anti-collision guardrail will also cause certain harm to the vehicle and the driver.
[0005] Therefore, it is necessary to invent a kind of highway traffic safety facility engineering anti-collision guardrail to solve the above problems. Utility Model Content

The I-shaped abutment steel 12 inside the connecting cross bar 8 strengthens the internal rigidity of the connecting cross bar 8. Combined with the external rigidity strengthened by the outer reinforcing rod sleeve 13, the entire connecting cross bar 8 no longer relies on its own material to resist the impact force, and has a good impact resistance effect on the impact force generated by a vehicle collision.
