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 reason for using corrugated road guard railing is that corrugated panels have better strength and impact resistance. Secondly, corrugated railing can save more materials. It uses the deformation of the ground base, columns and beams to absorb the collision energy and forces the runaway vehicle to change direction and return to the normal driving direction, preventing the vehicle from running off the road. , so as to protect the vehicle and passengers and reduce the loss caused by the accident. Also known as corrugated plate guardrail, galvanized plate guardrail, anti-collision guardrail, zinc steel W guardrail, highway guardrail. It is a security fence commonly used on roads and bridges at home and abroad. So what is the difference between double wave and triple wave railing wave?
Double wave handrail refers to the handrail with only two corrugations, and the height of each corrugation is 85mm.
Three-wave railing refers to the railing with three corrugations, and each corrugation has a height of 85mm.

The common point of double and triple wave guardrails is that they are all used for road protection and are the basic classification of wave guardrails.

The anti-collision level of double wave guardrail is weak, and it is often used on highways and rural roads that are not very critical; while the anti-collision level of the three-wave guardrail is higher and is suitable for more dangerous road sections such as highways, mountain roads and dangerous road sections.

difference between the two
The first is the difference in specifications. The wave guardrail is mainly to prevent runaway vehicles from running off the road. It is generally made of galvanized steel plate. Different specifications are adopted according to the grade of the road, so there are different wave guardrails, such as three-wave guardrails and double-wave wave guardrails. . The following is a comparison of the specifications of the two for reference:

Double wave wave handrail: 4320*310*85*3/4;

Three-wave wave guardrail: 4320*506*85*3/4;

Double wave column: 114/Ø140 mm×4.5 mm×height;

Three-wave column: 114/Ø140 mm×4.5 mm×height;

Second, there is a functional difference. The production specifications of the two are different and the anti-collision level is different. The anti-collision level of double wave guardrail is relatively weak, and it is often used on highways and rural roads that are not very critical; while the anti-collision level of the triple wave guardrail is higher and is suitable for the most dangerous road sections, such as highways, mountain roads, dangerous roads, etc.

Finally, there is the difference in the price of the wave railing. The uprights connected by the three-wave wave railing are square and can withstand stronger impact force, so their price is naturally more expensive. The double wave railing is equipped with round columns and the price is relatively cheaper.

FAQ

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.
