Introduction
Domestic and foreign traffic accident research data show that, reasonably set to meet the protection requirements of the guardrail, can effectively reduce the vehicle out of the roadside guardrail or through the secondary collision with the chances of collision, so as to avoid unnecessary property damage and casualties. Rolling crash barrier is mainly used in small radius curve section, tunnel entrance transition, interchange exit triangle end and other dangerous sections. The increase of car ownership makes the road bear the pressure of the vehicle running too much, easy to appear sudden traffic accidents. In the highway traffic accidents, a large number of accidents with the road on both sides of the guardrail collision-related. Guardrail design can make the runaway vehicle in collision with the guardrail to return to the normal direction of travel, maximum absorption of impact energy, reduce the injury to the driver and passengers.

1.Rotary anti-collision guardrail can be used as roadbed side guardrail, central partition guardrail, as well as bridge guardrail for small bridges, passages and culverts.
2.When the anti-collision surface of the rotary anti-collision guardrail does not coincide with the elevation of the curb stone, the height of the curb stone should be increased.
3.The compactness of roadbed in roadside and central partition zone should be strengthened by concrete foundation when necessary.
4.Transition treatment should be carried out between the rotary anti-collision guardrail and other types of guardrail.
5.Rotating barrel should be yellow, indicating warning.
6.When the revolving anti-collision guardrail is set on the left side or the central partition of the lane, the color of the reflective strip should be yellow, while the color of the reflective strip should be white when it is set on the right side of the lane.
The optional anti-collision guardrail is used as the end guardrail in the upstream direction of other guardrail, As shown in the figure.
When the radius of the horizontal curve is less than that specified in the table below, it is advisable to install a rotating anti-collision guardrail in the section of the horizontal curve.
The rotating guardrail is mainly composed of column, swing circle, rotating barrel, cross beam, waveform beam, reflective strip and corresponding connecting parts. The rotating barrel is made of a composite material of ethylene vinyl acetate copolymer (EVA) and polyurethane, which is elastic, impact resistant and wear resistant and can effectively prevent the rotating barrel from being shattered upon impact. The resilience of the barrel also ensures that it can be quickly restored to its original state after a severe impact. The barrel chosen by Suzhou Bypass Expressway Co., Ltd. is orange, which has a high brightness reflection effect and eye catching function, which can effectively improve the driver's attention and reduce the incidence of accidents, thus ensuring the safety of vehicles.
Features
(1) Fast opening.
The pluggable and removable structure enables 12 m (2 sections) to be opened and pushed in 3 minutes in case of emergency, far better than the norm of 10 m in 10 minutes.
(2) Safety upgrade.
Through rotational friction, the instantaneous impact energy is transformed into rotational energy and friction energy, effectively reducing the damage to the vehicle and the degree of injury to personnel.
(3) Material saving.
The simple shape of the product greatly saves material costs, using about 78 kg of material per linear metre, which is 50% to 80% of the material used in similar products in the current market.
(4) Beautiful shape.
The beautiful shape and beautiful rotating barrels have a good sight line guidance function, which can improve the road appearance and effectively ease the
The effect is more obvious especially at night and in rainy days.
(5) Easy to install.
The compact design of the product allows for easy installation on site after the unit has been assembled, greatly reducing the time spent on site and effectively reducing the risk of road-related operations.
(6) Simple maintenance.
The rotating bucket is made of EVA composite material, which is resistant to chemical corrosion, ageing and weathering, and is not easily damaged by vehicle impact, and does not need to be replaced during its service life (10 years).
