2.The composition of the wave guardrail
The corrugated guardrail is composed of two corrugated steel guardrail panels and two columns fixedly clamped between them. The two columns are fixedly clamped between the two corrugated steel guardrail panels.
3.Standards For Components Of Corrugated Beam Guardrails
Corrugated beams, columns, anti-blocking blocks, diaphragm beams, ends and other components should comply with relevant product standards.
The corrugated beam is the first structure that comes into contact with the out-of-control vehicle. Through the transmission of the corrugated beam, the collision force is dispersed to multiple columns, and the force is transmitted to the foundation soil through the columns. The interaction between the out-of-control vehicle and the guardrail will continue to change its position over time. The corrugated beam mainly bears tensile force. Under the impact of the collision vehicle, the ripples are spread out and absorb energy. In addition to meeting the tensile strength requirements, corrugated beams It also has good guiding and energy-absorbing properties.
The corrugated beam guardrail can be approximately regarded as a continuous beam supported by points on an elastic foundation. The collision force of a vehicle acting on the guardrail at a certain angle can be decomposed into a force acting perpendicularly to the guardrail and a force parallel to the guardrail. The vertical force causes the guardrail and columns to deform, and the parallel force causes the collision to continuously change the direction and position. The corrugated beams, columns and foundation soil jointly bear this collision force, and the corrugated beams mainly bear the tensile force. Columns mainly bear bending moments. During a collision, the uprights play a very important supporting role. In order to improve the strength of the column, it can be achieved by increasing the moment of inertia. The moment of inertia is affected by the cross-sectional shape and area of the column.
4.The Function Of Wave Guardrail
The corrugated guardrail is a combined corrugated plate movable steel guardrail used at the opening of the central separation zone of the highway. The guardrail consists of two corrugated steel guardrail panels and two columns fixedly clamped between them. The two columns are fixedly clamped between the two corrugated steel guardrail panels. During normal operation of the highway, the guardrail can be easily inserted into the pre-set plug-in hole at the opening using plug-in and pull-out columns to play the role of isolation and protection. At the same time, it echoes the guardrail belt on the outside of the highway, making it uniform and beautiful. When a vehicle collides with it, because the corrugated steel guardrail has good crash resistance and energy absorption, it is not easily destroyed, but at the same time it can play a very good role in protecting the vehicle and the passengers.
