The role of highway guardrails and installation precautions

The road guardrail separates the traffic of motor vehicles, non-motor vehicles and pedestrians, and separates the road longitudinally in the section, so that motor vehicles, non-motor vehicles and pedestrians can travel in separate lanes, which improves the safety of road traffic and improves traffic order;

How does the road marking machine work?

Road markings are also called road markings, that is, lines, arrows, signs, etc. which we can see on the road every day to identify traffic information, and play a role in traffic control and guidance. Next, the editor will take you to understand how road marking is constructed and what should be paid attention to during construction.

Selection of shock pad type and application location

When selecting and designing the crash pad, the size of the crash pad should be in accordance with the site conditions. In the event of a frontal collision and side collision, it can effectively protect obstacles and cannot encroach on the free space of the road. The Crash Pad can choose different structural shapes and use methods according to the terrain conditions and the degree of injury that may be caused in the event of a collision accident. Most of the anti-collision pads used on national roads are circular anti-collision cylinders made of glass fiber reinforced plastic, combined anti-collision pillars and other products.

What are the classifications of marking machines?

Vehicle-mounted marking machine: In the form of a driving bracket, the front and rear of the driving body are equipped with machinery, which is used in large-scale projects and long-distance construction marking. Operators must understand the skills driving and driving walking, saving time and effort.

Scratching machine and its accessories.

Width of marking lines: The width of international road markings is 15 cm. Considering that the marking machine can be used in parking lots, residential areas and other places, it is necessary to purchase a marking machine with a width adjustment function, which will help to use reasonably and save paint. The general adjustable range is 5-15cm.

crash pad design

The crash platform must be designed so that no fragments are ejected during the collision. After the frontal and side impact tests, the fragments produced by the crash pad must remain on the crash pad and cannot damage the collision vehicle, which surrounds it. Pedestrians and other vehicles cause damage.

What is the difference between the second wave and the third wave of the highway wave guardrail?

Corrugated guardrail is the main form of semi-rigid guardrail. It is a continuous structure spliced ​​with corrugated steel guardrails and supported by the main column. It is generally processed by galvanized steel plates.

The installation position of the corrugated guardrail has different anti-collision performance

The configuration of the wave beam guardrail board depends on different road conditions and configuration positions, and its anti-collision performance requirements are different. The guardrails installed on the roadbed are divided into two levels A and S according to the anti-collision level, and the anti-collision level of the middle dividing guardrail is Am and Sm. Through the general protection of the handrail and the correct guidance of the vehicle, it is an integral action to guarantee the safety of the occupants of the vehicle from collision. Before laying out, you should be familiar with the route and layout of bridges and culverts along the line, and give them full consideration;
