EVA Filled 350X500mm Yellow Barrel Highway Roller Safety Guardrail
Qingdao Taicheng Transportation Facilities Co., Ltd, subsidiary of Qingdao Henger Group, is a technology-innovative company, based in Jinkou Industry of Qingdao City. Taicheng is devoting to improve the world road safety cause by creative R&D team, advanced production technique, high class manufacturing machines, complete testing method, reliable product quality and enthusiastic service
It is especially suitable for installation in accident-prone areas such as tunnel openings, central isolation belts, sharp turning areas, and complex intersections. Because of its good anti-collision performance, it can also be used as defensive equipment various power facilities, parking lot columns, large shelf angles and other objects.
Rotating anti-collision guardrail principle of work
Rotating collision barrier to change the traditional guardrail single side of the waveform beam type, using a column double side guardrail, that is, in the column on both sides of the installation of waveform beam guardrail. The middle of the installation of rotating anti-collision barrel, in the rotating barrel of the upper and lower are installed waveform guardrail, so that a column will be installed on the four-waveform beam, that is, "a column of four columns" strengthen the type of guardrail. This enhanced guardrail device can effectively prevent cars from crossing the guardrail out of the road, and the rotating barrel posted on the two eye-catching reflective strips (circle), can maximize the warning to drivers and passengers to pay attention to safety, effectively reduce the rate of traffic accidents. When the vehicle hits the guardrail, first will collide with the rotating barrel contact, then, the vehicle with the rotating barrel rotation, driving speed gradually decreased, at the same time, the impact energy generated by the collision is rotating barrel significantly absorbed, can effectively reduce the consequences of traffic accidents.
Structure of Qingdao Taicheng Safety Roller
The main components of rotating collision avoidance guardrail
The rotating collision barrier is mainly composed of columns, swing circles, rotating barrels, beams, waveform beams, reflective strips and the corresponding connecting parts. The rotating barrel is made of ethylene vinyl acetate copolymer (EVA) and polyurethane composite material, which is elastic, anti-collision and wear-resistant and can effectively avoid the rotating barrel from being broken by impact. At the same time, the good recovery force of the rotating bucket also ensures that it can be quickly restored to its original state after a serious impact. In addition, the color of the rotating barrel is bright, white, yellow, orange, etc. The barrel was chosen by Suzhou Bypass Expressway Co., Ltd. is orange, which has high brightness reflection effect and eye-catching function, which can effectively improve the driver's attention and reduce the accident rate, thus ensuring the safety of the vehicle.
Construction process of rotating anti-collision guardrail
·Column installation
Use the pile driver to drive the column vertically into the road. If the road base is particularly hard, the column can't go down, use the drilling machine to punch the hole and then install the column. After the verticality and elevation check of the column is completed, the column will be backfilled and pounded with C20 concrete.
·U-frame installation
The two U-frames are fixed with M20×180mm hexagonal bolts on the Φ20 counterbore of the lower part of the column. It should be noted that the nuts need not be tightened for the later installation and commissioning.
·Lower guardrail installation
First, along the U-slot will be M20 × 60mm half-round head waist neck bolts with square pad buckle into, then, the guardrail first and last two bolts and U-frame on the U-slot fixed, and then install the other bolts.
·The installation of the gyratory ring
After the installation of the two lower guardrails, on the column set on the swing ring.
·Installation of swing barrel
In each column on the set of a swing barrel, and then on the swing barrel on the swing ring.
·The installation of the upper guardrail
The installation method is the same as the installation method of the lower guardrail. First, along the U groove will be M20 × 60mm half round head waist neck bolts with square pad buckle into, and then, all the bolts on the guardrail will be inserted into the top hole of the column, with nuts fixed tight.
·Between the guardrail connection
Use the connecting frame to connect the adjacent guardrail, after a section of guardrail is installed, the connecting frame will be inserted into one end of the guardrail and fixed, so that the next section of the guardrail splices.
·Guardrail and the end of the connection
The end will be set into the guardrail, with M20 × 140mm bolts to fix it.
·The installation of the end cover
After the above installation steps are completed, adjust the guardrail line, tighten all the nuts, the end cover set on the column can be fastened.

Highway Anti-collision Polyurethane Rotating Barrier Introduction
The anti-collision road roller guardrail is a new type of product. It is assembled with PU/EVA rollers and galvanized steel columns and beams. But it is different from w-beam guardrail. It can absorb the impact and guide the vehicle to the direction of the road through the rollers, convert the impact energy into forward kinetic energy, so as to prevent major accidents, and can reduce the damage to the vehicle and human body in the event of an accident. Moreover, the rollers are lighter than the w-beam guardrail, and the installation is more convenient. Recoverable after attachment, easy to maintain. long lasting.
