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).

The rotary anti-collision guardrail is composed of rotating barrel,
beam, column, reflective strip, casing, rotating coil and
connecting piece.he exploded view is as follows:
Main components
The rotating collision guardrail is mainly composed of column,
rotating barrel, casing, rubber cushion, swivel ring, beam,
reflective strip and bolt. The side view of the guardrail is shown
in the figure, using a column and four columns of the installation
method.
Composition
The rolling safety barrier is made of ethylene vinyl acetate
copolymer (EVA) and polyurethane composite material, which is
elastic, impact-resistant and wear-resistant and can effectively
prevent the rotating barrel from being shattered upon impact, and
the good recovery force of the rotating barrel also ensures that it
can quickly return to its original state after a serious impact.
Rotary anti-collision guardrail constitutes the outline - the deviation of the outer dimensions of the rotating anti-collision guardrail member is allowed 5%
