Corrugated guardrail is a common traffic safety facility, which is widely used in highways, bridges, tunnels and other traffic sections. A corrugated guardrail consists of a series of corrugated beams that are fixed to the uprights by means of connectors to form a continuous guardrail. The corrugated beam of the corrugated guardrail is a corrugated steel plate, which has good impact resistance and the ability to absorb energy, which can effectively reduce the injury to the vehicle and personnel when the vehicle is impacted. So, how many forms of corrugated guardrails are there? This will be explained in more detail below.
Corrugated guardrails come in many forms, and here are the common ones:
1. Straight rod corrugated guardrail
Straight bar corrugated guardrail is the most common form of corrugated guardrail, consisting of a series of straight rods and corrugated beams. Straight rods are usually made of steel pipes, H-shaped steel, and other materials, which have strong bending and impact resistance. The straight rod corrugated guardrail has a simple structure and easy installation, and is suitable for the protection of various roads and bridges.
2. Oblique rod corrugated guardrail
Diagonal bar corrugated guardrail is a special form of corrugated guardrail, which is characterized by the oblique connection between the column and the beam. This form of guardrail has strong lateral collision resistance, and is suitable for road sections that need to improve the safety protection level such as mountainous areas and steep road sections. The inclined rod of the inclined rod type corrugated guardrail is usually made of steel pipe or H-shaped steel, which has strong bending and shear resistance.
3. Combined corrugated guardrail
Combined corrugated guardrail is a form of corrugated guardrail that combines the characteristics of straight rod type and oblique rod type. It consists of straight rods, oblique rods, and corrugated beams, which are held together by special connections. The combined corrugated guardrail has strong impact resistance and lateral collision resistance, and also has a good aesthetic effect, which is suitable for highways and other road sections that require a high safety protection level.
4. Concrete corrugated guardrail
Concrete corrugated guardrail is a form of corrugated guardrail with concrete as the main material. Its columns are usually made of concrete, which has strong impact resistance and durability. Concrete corrugated guardrail is suitable for some special road sections, such as bridges, tunnels, etc., which can provide better safety protection effect.
The above are several common forms of corrugated guardrails, each of which has its own characteristics and scope of use. In practical application, it is necessary to comprehensively consider the selection of suitable corrugated guardrail form according to road safety requirements, topography, material cost and other factors.
In addition to the above common forms of corrugated guardrails, there are also some special forms of corrugated guardrails, such as wavy guardrails, triangular guardrails, etc. These special forms of guardrails are usually designed to adapt to special road conditions or improve safety protection, and also have a wide range of applications in practical applications.
Corrugated guardrail is an important traffic safety facility, and its forms are varied. Understanding the characteristics and scope of use of different forms of corrugated guardrails is of great significance for improving the level of road safety. Corrugated guardrails
