highway guardrail systems used description

highway guardrail systems used is a protective system. As the highest form of highway, Expressway plays an important role in promoting national economic development.

High-speed guardrail and cable guardrail are both products of Expressway protection.highway guardrail systems used have similar functions and protective functions, but they have their own shortcomings and advantages.

highway guardrail systems used there is no single protective equipment on the expressway, so the combination of the two is needed to better protect the smooth flow of the expressway and the safety of the expressway. Next let's look at the advantages and disadvantages of high-speed guardrail and cable guardrail.

Protection effect: The anti-collision grade of the cable guardrail and the guardrail board has highway guardrail systems used own protection level: A, B and S, but the protection effect of the cable guardrail is obviously better than that of the guardrail board.

highway guardrail systems used the cable guardrail cable consists of several wire ropes. The anti-collision and self-recovery ability of the wire rope is very strong. The guardrail is composed of corrugated steel plate, which can absorb the impact force of the car very well, but highway guardrail systems used self-recovery ability is poor. The guardrail after impact needs to be replaced.

Anti-corrosion aspect: There are many kinds of anti-corrosion methods for cable guardrail and guardrail, but they are basically treated by hot-dip galvanizing. The anti-corrosion effect of hot-dip galvanized products is very excellent and can be used normally for decades under outdoor conditions. Therefore, the anti-corrosion effect of two kinds of road protection products is very good.

Column firmness comparison: there are many types of guardrail column specifications, which are selected according to the engineering requirements. The column size range of cable guardrail is smaller, but the diameter and wall thickness of the column are obviously better than those of the guardrail plate. Therefore, the degree of firmness is obviously better than the guardrail column.

Maintenance: Cable guardrail has a small amount of maintenance, generally will not occur a large degree of deformation, so the number of replacements is less.

Guardrail has a higher amount of maintenance, once a vehicle collision accident occurs, the guardrail generally needs to be replaced, because it needs its own deformation to reduce the impact force. So the maintenance of the guardrail is obviously higher than that of the cable guardrail.

Price: Through the introduction of the above points, highway guardrail systems used is not difficult to find that the advantages of the cable fence are obvious, but the price of the cable fence is higher than the fence board.

highway guardrail systems used because the cost of the fence board is lower, so there are more places to install the fence board on the highway. But highway guardrail systems used is very important to install cable fence in some dangerous areas, such as coastal highway, side cliff highway, mountain section and so on.

The guardrail panels are joined together by splicing bolts, and are fixed on the columns or beams by connecting bolts. Connecting bolts and splicing bolts should not be tightened prematurely, so that long circular holes of corrugated beams can be adjusted in time during installation to form smooth lines and avoid local concave and convex.

highway guardrail systems used with the construction and development of highway, the management and maintenance of highway is becoming more and more important. Highway has the characteristics of fully enclosed one-way traffic and a variety of transport engineering facilities.
