What is traffic barrier？

The road barricades is a kind of traffic safety device which is set on the outside of the road shoulder, the traffic separation belt and the pedestrian road tooth.The collision energy can be absorbed by self-deformation or vehicle climbing, so as to change the direction of the vehicle, prevent the vehicle from going out of the way or entering the heading lane, and minimize the damage to passengers.

Description of plastic safety barriers

Roadside guardrails are used to protect vehicles and people inside them from being hit by natural or man-made objects near the road.It is important to note that the impact of a vehicle on a traffic guardrail may damageboth the vehicle/passenger and the guardrail itself.The damage caused by collision guardrails is usually less serious than that caused by collision of components behind guardrails, so traffic guardrails represent a compromise between the two considerations.In addition to protecting vehicles, traffic barriers are also used to screen pedestrians, maintenance/construction personnel, or bicyclists from irregular traffic.In its most basic form, traffic barriers are designed to prevent vehicles leaving the driveway from bumping into stationary objects.The guardrail first blocked an accident vehicle and then changed its direction.Because of the variability of vehicle impact and the damage effect at high speed, comprehensive full-size damage test should be introduced to ensure the safety and reliability of the traffic guardrail to be used.

Guardrails can be used in many sizes and shapes.The choice of guardrail type depends on a variety of factors, including the environment of the road and the speed and traffic volume.

The functions of street barricades:

One is to prevent outside the vehicle out cause rollover accidents, especially set up the bend in the mountains, where the traffic guardrails, for motor vehicle drivers, in the distance can be sufficient attention, make its vigilance, can the driver for the line of sight when by induction, to help its correct operation,

Second, it can prevent the head-on collision against the head-on car and prevent the collision and suspension of the same car.

Third, it can prevent vehicles from colliding with pedestrians and prevent pedestrians from crossing the road at will.

Maintenance of plastic traffic barricades

1.Inspection of traffic control barricades

The inspection of traffic guardrail includes routine inspection and regular inspection every quarter. The inspection content is as follows:

(1) there is no damage or deformation of all kinds of guardrail structure parts, and the fastening of columns and horizontal components.

(2) pollution level and paint condition.

(3) relaxation of the cable.

(4) defect of guardrail and reflective film.

2.Maintenance and maintenance

(1) weeds and other accumulated debris around guardrails shall be frequently removed.

(2) the guardrail shall be painted in time if the paint falls off.

(3) any defect or deformation of guardrails caused by traffic accidents or natural disasters shall be replaced or replaced in time.

(4) if the elevation of guardrail changes significantly due to road reinforcement or adjustment of the longitudinal section of roadbed, the height of guardrail shall be adjusted accordingly.

(5) seriously corroded guardrails shall be replaced.
