crash barrier

crash barrier introduce

crash barrier also called the "two wave highway guardrail" is the main form of semi steel guardrail. crash barrier is a continuous structure which is spliced with the corrugated steel guardrail and supported by the main column.

crash barrier uses the deformation of the soil foundation, column and beam to absorb the energy of collision, and force the out of control vehicle to change direction, return to the normal driving direction, prevent the vehicle from out of the road, to protect the vehicle and passengers and reduce the loss caused by the accident.

The soft phase and soft phase of the freeway crash barrier has a strong ability to absorb the energy of collision. It has good line of sight induction function, can coordinate with the line shape of the road, the shape is beautiful, it can be used in the small radius bend, and the damage place is easy to replace. Combined wave beam guardrail can be used in narrow central dividers. For the section that may cause serious consequences outside the vehicle outlet (bridge), the corrugated beam guardrail can be selected.

The crash barrier is made up of two columns of corrugated steel guardrail and two fixed posts and fixed between them. The two columns are fixed between two corrugated steel guardrails. In the normal operation of the highway, the guardrail can be conveniently inserted into the prearranged pluggable hole in the opening by using the plugged column, and it can play the role of isolation and protection. At the same time, it corresponds to the guardrail belt on the outside of the highway.

When vehicles collide, the corrugated steel crash barrier has good impact resistance and absorbs energy, and it is not easy to be knocked down, and it can also play a good role in protecting vehicles and personnel. When pavement maintenance or other reasons need to be connected, it is convenient to pull and remove the guardrail columns at each opening, and open up passageways, which is convenient for vehicles to pass through.

Classification of crash barrier

Corrugated crash barrier are generally classified according to the location and level of collision avoidance. According to the location can be divided into the roadside guardrail and the median divider. The form of wave shield: wave beam guardrail is the main form of semi rigid guardrail. It is a continuous structure which is spliced with corrugated steel guardrail and supported by main column. According to the grade of collision avoidance, it can be divided into class A and S. The S level is enhanced barrier, suitable for use in the roadside especially dangerous road, a road for.

The utility model of a crash barrier involves a composite corrugated plate movable steel guardrail for the opening of the central section of a highway. The guardrail is composed of two columns of corrugated steel guardrail and two vertical columns fixed between them. The two columns are fixed in two sheet steel guardrails. When the highway is running normally, the fence will be inserted and pulled up.The column can be conveniently inserted into the prearranged pluggable hole at the opening to play the role of isolation and protection. At the same time, it corresponds to the guardrail belt on the outside of the highway. When the vehicle collides with it, due to the corrugated steel

The crash barrier has good crashworthiness and energy absorption function, it is not easy to be crashed, but also can play a good protective role for vehicles and passengers. When pavement maintenance or other reasons need to be connected, it is convenient to pull and remove the guardrail columns at each opening, and open up passageways, which is convenient for vehicles to pass through.
