FAQ
- What is a highway guardrail drilling machine? What's the difference between it and highway guardrail and pile driver?
- However, as far as I am concerned, the highway guardrail drilling machine is a more advanced engineering equipment, so it is not very common in the market, and only a few other enterprises can produce it. Because the highway guardrail drilling machine is a machine called "macro road machinery" enterprises to develop their own production and application, patent protection has been made, so the relevant knowledge on the market is relatively small.
- Traffic, driver's license subjects, in the highway driving vehicle crash barrier, what protection measures?
- The vehicle on the highway guardrail accidents, if the driver quickly take emergency braking, or greatly to the opposite direction, or to the side of the collision will cause serious vehicle steering, out of control, continuous collision guardrail, tilting, and other major traffic accidents over the fence.The vehicle on the highway guardrail crash accident of the moment, the driver should firmly hold the steering wheel steady direction, modified to control the vehicle bounce; avoid emergency braking, jerked the steering wheel or quickly to the opposite direction to escape, so as to avoid the expansion of the accident.

A road without setting and overpass or underpass bike location, pedestrian safety management should be set up in other label records, highway, according to the actual situation, set the necessary overpass or underpass.
- What is the standard height of highway guardrail design?
- The main consideration of the height of guardrail is the density of people and the terrain along it. 6 specifications for the use of cold-formed equilateral channel steel are provided for different force conditions, while other appropriate cross section steel is also available under the condition of strength and stability. From the main force direction of the channel column, the choice of specifications should make the core of the Y-Y axis (Iy) larger channel steel. The effective height of the national JTJ074-94 fence standard ranges from 1.6~1.8m, and this range of values takes into account the adult height to prevent crossing as the main design goal. It is observed that if people want to enter the highway, they usually destroy the guardrail, and the damage position is below 1.2m. Set up a high fence, although it can better prevent people from crossing, but it can not prevent people from entering the highway. What can really regulate people's behavior is legal awareness and social civilization. With the development of society and the improvement of people's legal consciousness, the number of people who violate traffic laws is bound to decline. Britain and other developed countries highway double ring fence design height is about 1.3 meters. Therefore, the fence should not be set too high, it is recommended in the general area, fence exposed height in the 1.2m-1.5m can be, the special areas in 1.6m is appropriate. This height of people is not easy to cross, but also saves investment. How much is the spacing between the posts of the guardrail net; because the height of the fence post is lowered, it is suggested that the column spacing should be 4m, and that it should be set at 201 5m per kilometre;
