Idea for Highway guardrail design

Idea for Highway guardrail design 

The highway guardrail barrier can also be called high speed road wave beam guardrail, highway guardrail, wave guardrail, guardrail protector board, engineering wave guardrail board, guardrail board, bridge guardrail, bridge guardrail board, etc. Two wave waveform guardrails and three wave guardrails.

Highway wave guardrails are generally classified by location and collision level. According to the setting location, it can be divided into a roadside guardrail and a central divider with a guardrail. According to the anti-collision level, it can be divided into A level and S level. The S-class guardrail is of a reinforced type and is suitable for use on particularly dangerous road sections on the road side. Class A is used for special roads.

Highway guardrail design refer working principle:

1. The highway guardrail is the main form of semi-steel guardrail. It is a continuous structure in which corrugated steel guardrails are spliced ​​to each other and supported by columns.

2. It uses the deformation of soil foundation, column and beam to absorb the collision energy, and forces the out-of-control vehicle to change direction and return to the normal driving direction to prevent the vehicle from rushing out of the road to protect the vehicle and passengers and reduce the losses caused by the accident.

3. The highway guardrail steel is soft and phase-strength, has strong ability to absorb collision energy, has good line-of-sight induction function, can coordinate with the road line shape, has beautiful appearance, can be used on small radius curves, and the damage is easy replace.

The highway anti-collision guardrail ensures the safety of the vehicle during the road. It can be said that the beam guardrail is an indispensable facility on the road. If it is limited by space, it is inconvenient to separately set the safety anti-collision guardrail, and the safety high-speed anti-collision guardrail and the noise barrier can be integrated into one design.

The expressway guardrail is prone to problems?

1. When an accident occurs during the running of the vehicle, when it suddenly rushes out of the roadway, it may collide with some independent obstacles on the roadside, such as: bridge piers, door type signal signs. Frames, large traffic sign posts and high-voltage power line tower bases, etc. 2. There are continuous physical obstacles on the outside of the curb, such as retaining walls, etc., or the steep slope of the rock of the road is less than 4.5 meters from the curb. 3. In the section of noise barrier with anti-noise, when the freeway barrier is less than 0.5 m from the curb, a safe high-speed anti-collision guardrail shall be provided.
