Introduction

In order to avoid the vehicle in a collision when driving out of the road range, to reduce the degree of traffic accident damage, the central divider of the highway and both sides of the road are set up with anti-collision guardrail. The common form of anti-collision guardrail is concrete guardrail, waveform beam guardrail and cable guardrail, which, cable guardrail is a flexible guardrail, which absorbs the energy generated by the vehicle collision is limited, so less application.

At present, the main application of the highway is the concrete guardrail and waveform beam guardrail. The former belongs to the rigid guardrail, the latter belongs to the semi-rigid guardrail, these two guardrails have a better anti-collision effect, but in the vehicle after the collision, or will produce a large damage. At the same time, due to these two guardrails on the contour marker area is small, with the passage of time will produce a lot of dust, resulting in the guardrail reflective warning effect getting worse.

In order to improve the safety of passing vehicles, the driver's alertness, especially accident-prone areas and small radius ramps vehicle driving safety. Rotating collision barrier after more than a year of pilot application, from the traffic police, road administration and the feedback from the barrier department, the pilot section of traffic accident frequency significantly reduced, the degree of damage caused by the accident also significantly reduced.

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.

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.
