Details of Highway Guardrail

Pulished on Apr. 01, 2020

Highway mesh panel fencing is the main form of the semi-rigid guardrail. It is a continuous structure with corrugated steel guardrail panels spliced to each other and supported by the main column. When the vehicle collides with it, because the corrugated steel guardrail has good impact resistance and energy absorption, it is not easy to be crashed, and at the same time, it can protect the vehicle and the passengers.

classification:

According to the surface treatment, it is divided into hot dipped galvanized mesh panel fencing and hot-dipped galvanized mesh panel fencing.

According to the setting place, it can be divided into roadside guardrails and central divider guardrails.

It can be divided into A-level and S-level according to the anti-collision level. The S-type guardrail is a reinforced type, which is suitable for use on particularly dangerous sections of the roadside, and the A-grade is used for special highways. The commonly used roadside wave beam guardrails can be divided into five levels of B, A, SB, SA, and SS according to the collision level.

principle:

1. The highway guardrail is the main form of a semi-rigid guardrail. It is a continuous structure with corrugated steel guardrail panels spliced to each other and supported by columns.

2. It uses the deformation of the soil foundation, columns, and beams to absorb collision energy, and forces the uncontrolled vehicle to change direction and return to the normal driving direction to prevent the vehicle from rushing out of the road to protect the vehicle and passengers and reduce losses caused by the accident.

3. The corrugated beam guardrail is both flexible and flexible. It has a strong ability to absorb collision energy, has a good line of sight induction function, can coordinate with the road alignment, and has a beautiful appearance. It can be used on small radius curves, and the damaged area is easy to replace.

Features and uses:

The bending of expressway guardrails will increase the aesthetics and increase the strength of the slabs at the same time. It will have both. The automatic production line is extruded and formed, the surface is clean and undamaged, and the corrosion resistance is very strong. The surface treatment method is mature; Features of sunlight, high-temperature resistance, low temperature, etc., the service life in outdoor environment can reach 10-25 years; the product structure is simple, beautiful and practical, easy to transport and install, the anti-theft performance is good, limited by the actual terrain, for mountainous, sloping, multi-curved The zone is extremely adaptable, the cost is moderate, and it is suitable for large-scale adoption.

It is mainly used in the construction of safety and anti-collision projects such as highways, large parking lots, scenic spots, high-speed highways, provincial roads, and rural roads.

At present, the anti-fence ability of expressway fence nets will be a more important factor in the scientific and systematic use of fence nets. As the surface of expressway fence nets has certain woven mesh characteristics, in other aspects, it will stretch. And the ability of meeting will be a more important manifestation. It is precisely through the use of this scientific system to use the fence net that it will have more value in terms of highway opening and safety protection. It becomes very important that we use it scientifically. As for how the highway fence network can be calculated to obtain the high-quality fence network structure characteristics, many friends have used the technical level to get the corresponding technical answer, that is, a full set of use, and simulation inspection.
