EVA material road rotating anti-collision bucket with reflective
strip
1. Small radius curve section
Small radius curves may affect the stopping sight distance in the
center divider, requiring increased driver attention to reduce
reaction time, and small radius curves require higher line of sight
guidance to remind drivers to maneuver better. The use of rotating
crash barriers on small radius curves and the color of the rotating
barrels will have a visual impact on the driver, creating an
enhanced line of sight guidance.
The rotating bucket is made of composite material of EVA and
polyurethane. This high-strength EVA and polyurethane material
itself is elastic and anti-collision and wear-resistant, which can
prevent the rotating bucket from being smashed when it is impacted,
and effectively protect the guardrail and passengers. . In addition
to good anti-collision and wear resistance, it also has the
advantages of anti-chemical corrosion, anti-ultraviolet aging, and
weather resistance.s.
Material characteristics: The rotating bucket is made of EVA and
polyurethane composite material, which is elastic and
anti-collision and wear-resistant, which can prevent the rotating
bucket from being crushed when it is impacted, and effectively
protect the guardrail and passengers. In addition to good
anti-collision and wear resistance, it also has the advantages of
anti-chemical corrosion, anti-ultraviolet aging, and weather
resistance.
Tunnel entrance transition
The different widths of roadbed (bridge) and tunnel cross-sections
are important reasons for the high number of accidents at tunnel
entrances, which require the transition of guardrails to complete
the cross-section change. The rolling barrier is used in the tunnel
entrance, which can provide a strong enough guidance function to
assist the driver to complete the road environment change under the
premise of ensuring the collision prevention demand.
Product Structure
Parts and Installation:
1) Column: It is driven into the roadbed and is the main
force-bearing component.
2) Beam: It is used for the connection between the columns and to
fix the rotating barrel.
3) Rotary barrel: It is fixed between the upper and lower beams and
can be rotated around the column. The main materials are EVA
(ethylene-ester acid copolymer) and polyurethane.
4) Sleeve: installed on the inner wall of the rotating barrel, the
contact part of the rotating function.
5) Gyratory ring: Installed between the rotating barrel and the
beam to balance and promote rotation.
6) Connecting frame: used for connection between beams.
7) U-shaped frame: connect the beam and the column to fix the beam.
8) Pad buckle: Lined with the beam and connected to the U-shaped
frame.
9) Hoop: connecting beam and column, used to fix the beam, suitable
for specific models.
10) Reflective strips.•It is a reflective film, which is pasted on
the rotating barrel and plays an inductive role.
Scope of application: It is especially suitable for installation
and application in accident-prone areas such as tunnel entrances,
central isolation belts, sharp turning areas, and complex
intersections. It is worth mentioning that the rotating barrel also
has a strong resilience, even if it is severely impacted, it can
immediately return to its original state.
