Description

Upright post inserted type bridge combined guardrail structure

Technical Field

The utility model relates to a bayonet bridge combination guardrail structure of stand in highway safety protection field.

Background

Along with the development of the transportation industry, the increase of the traffic flow and the upsizing of vehicles, the traffic pressure of roads is gradually increased, and the safety protection requirement of the roads on guardrails is correspondingly improved. The highway guardrail is arranged on the last defense line of the accident vehicle on the highway, and the reasonably designed highway guardrail can effectively reduce the accident injury degree and save the lives of passengers. Once a bridge section on a highway is at a high position, major accidents of vehicle damage and human death are easily caused once accidents of vehicles crossing or crossing a bridge guardrail occur. Common bridge railing includes concrete guardrail, beam column type steel guardrail, combination formula guardrail, and wherein combination formula guardrail lower part is the concrete base, and upper portion is the beam column type steel construction, and upper portion beam column type steel construction adopts buried bolt's mode anchor in the concrete base usually, and this kind of guardrail structure has had concrete guardrail and beam column type steel guardrail's characteristics concurrently.

The earliest combined guardrail on the expressway is designed according to technical specifications of expressway traffic safety design and construction (JTJ 074-94) issued in 1994, but the safety performance of the old combined bridge guardrail has defects for the current traffic characteristics, and the statistics of accident data show that: after a vehicle collides with the combined bridge guardrail, the lower part of the guardrail is mostly intact, the cross beams and the upright columns on the upper part of the guardrail are seriously damaged, most of the cross beams and the upright columns are broken by collision, and the length of the cross beams and the upright columns is more than 10m, which indicates that the rigidity of the upper part structure is seriously insufficient; after a vehicle collides with the combined bridge guardrail, the head of the vehicle often cannot effectively steer, and the vehicle is blocked at the position of the upright column due to the fact that the upright column is too close to the collision surface of the guardrail. Therefore, when designing the combined guardrail, the problems of matching of the upper and lower structural rigidity and the distance between the upright post and the guardrail on the collision surface are considered emphatically.

The novel combined guardrail structure is characterized in that a blocking prevention block is arranged between an upright post and a cross beam, and the distance between the upright post and a collision surface of a guardrail is increased so as to reduce the vehicle stumbling condition; the upright posts are fixed by inserting the upright posts into the embedded components and pouring cement mortar, so that the construction convenience is improved; the material quantity is reduced and the manufacturing cost is saved through comprehensive structure optimization.
