standard highway guardrail design

standard highway guardrail design introduce

standard highway guardrail design is divided into five grades: B grade, A grade, SB grade, SB grade and SS grade. On the more important highways, three wave guardrails are generally adopted. The anti-collision coefficient of the three wave shields is more Ok, for some country roads, the guardrail board can be equipped with a B-class guardrail board, and the price is cheaper.

standard highway guardrail design in order to ensure traffic safety, reduce the principle of standard highway guardrail design property damage and casualties, and give full play to the operational benefits and economic benefits of highways, safety facilities engineering is an important project to ensure traffic safety.

Therefore, the construction quality of traffic safety facilities directly affects the overall quality of highway engineering, and the realization of the overall function and the operation of highway operation benefits.

Highway guardrail setting mode:The barrier protection is designed as a barrier to reduce or mitigate the damage caused by the accident. So consider the quality of the car and the speed and angle of the car collision.

The use should also be considered in designing a guardrail that is comfortable and safe, and the driver's visual and psychological response barriers intuitively and naturally guide the driver's line of sight. For example, in a dangerous part,

highway safety guardrail

standard highway guardrail design is easy to fear, and it is also possible to use a beam guardrail, or a concrete barrier to block the line of sight of the user.The road conditions are strictly in accordance with national technical standards for highway engineering, embankment height, and slope. Median, shoulder width, etc.

With the improvement of China's economic level, there are certain gaps in the standards for the structure of vehicles. Heavy trucks in the number and direction of small cars and trucks. Although the number of small cars has increased a lot,

the passenger capacity has dropped, and the large trucks collided with the guardrails, and the guardrails easily hit the roads, which inevitably caused secondary injuries.

Therefore, we need to consider increasing the number of large trucks, so that the cars can pass through dedicated lines to reduce the traffic pressure of the highway during construction.

standard highway guardrail design description

Vehicle collision angle and speed: According to the accident site, we should consider the speed of the vehicle driving on the highway, standard highway guardrail design can ensure the strength of the fence when the accident occurs, prevent secondary accidents.

standard highway guardrail design and strictly calculate according to relevant regulations to determine the need Install the fence. Therefore, in the necessary links, strict measures should be taken to limit the speed limit of large trucks and cars, which can effectively avoid traffic accidents.

Construction quality control of corrugated guardrail: The section of the central divider and the embankment fill height is greater than or equal to 3m, and the corrugated beam guardrail is set.

standard highway guardrail design according to the design requirements, only the central divider with wave guardrails is installed in this section. The wave guardrail on the central divider belt adopts standard highway guardrail design Am-level wave guardrail. The general section spacing of the column is 4m, the end section is 2m,

and the adjustment section of the section is set between 1~3 sections between the general section and the end section. See the relevant drawings for the spacing of the adjustment section. The section adopts the driving type construction, and the end reinforcement section is reinforced by the embedded construction base.

The construction process of the corrugated beam steel guardrail is as follows:At the beginning of the construction of the guardrail, the laying work should be done first to ensure that the position tolerance of the steel plate is within the allowable range and then verified.

standard highway guardrail design after the corrugated board is installed, the linear adjustment is performed to ensure that the corrugated beam has a good line shape and meets the technical specifications. Finally, conduct self-inspection and clean up the site work, and prepare for acceptance.
