Highway guardrail every bit of distance on the signage made of reflective materials, normal straight section 50 m 1, 20 m 1 curve, ramp 5 m / a, with a very obvious warning effect, this signage surface coated with a layer of reflective rate of high fluorescent paint, can be various angles of incidence of light reflection out of the relative concentration of parallel light. In the absence of light conditions will show very dark, once there is light shot to the surface of the signage, it will shoot back in the direction from which it came. Highway in front of the role of reflective panels, road width, corner, slope at a glance!

Waveform guardrail plate construction precautions

2016-10-14

Waveform guardrail plate construction precautions 1). Construction preparation should be sufficient, construction section pile number location to find accurate. Sampling should be accurate, the error is within the specified range.　　2). Column construction should be strict and careful, its verticality, spacing, bolt hole location and other dimensions should meet the requirements, do not meet the requirements need to rework immediately, at the same time, should be strictly in accordance with the provisions of the specification JTJ074-94 rework.　　3). Waveform beam plate, column and other components of the packaging and marking should be in line with the provisions of GB6725. The guardrail shall not be bulked when purchased, and it should be ensured that the products are not deformed or damaged (injured) during lifting, transport and stacking.

What are all the road traffic safety facilities?

2016-10-13

Road traffic safety facilities play an important role in ensuring driving safety and reducing the extent of potential accidents. Good safety facilities system should have traffic management, safety protection, traffic guidance, isolation and closure, glare prevention and other functions. Road traffic safety facilities include: traffic signs, road markings, guardrails, barriers, lighting equipment, sight-inducing markers, anti-glare facilities and so on. Highway safety guardrail should not only stop the vehicle out of the road, to prevent the vehicle through the central divider into the opposite lane; at the same time, it should also be able to induce the driver's line of sight. The barrier is one of the infrastructures of the highway, which makes the highway fully closed to be realised
