highway guardrail post

highway guardrail post application

The highway guardrail post is buried in the soil, and its function is to support the highway guardrail. Highway guardrail post has many kinds of specifications and shapes, such as round, U, C, SIGMA highway guardrail post.

The highway guardrail post is a movable steel guardrail with a combined wave plate at the opening of the central section of the highway. The guardrail is composed of two columns of corrugated steel guardrail and two vertical columns fixed between them. The two highway guardrail post are fixed between two corrugated steel guardrails.

In the normal operation of the highway guardrail post, the guardrail can be conveniently inserted into the prearranged pluggable hole in the opening by using the plugged column, and it can play the role of isolation and protection. At the same time, it corresponds to the guardrail belt on the outside of the highway. When the vehicles collide, the corrugated steel guardrail has good impact resistance and absorbs energy, and it is not easy to be knocked down, and it can also play a good protective effect on the vehicle and the crew.

1、highway guardrail post is the main form of semi steel guardrail. It is a continuous structure with corrugated steel guardrail plates spliced together and supported by columns.

2、It uses the deformation of the soil foundation, the column and the beam to absorb the collision energy, and force the out of control vehicle to change direction, return to the normal direction of driving, prevent the vehicle from running out of the road, to protect the vehicles and passengers and reduce the loss caused by the accident.

3、The highway guardrail post flexible phase also has the strong ability to absorb the energy of collision, and has the better line of sight induction function. It can coordinate with the line shape of the road, the shape is beautiful, it can be used on the small radius bend, and the damage place is easy to replace.

4.The highway guardrail post is installed in the middle of the road. When the vehicle is out of control, it can effectively prevent the out of control vehicle from going to the opposite lane for two collisions.

5. The highway guardrail post is a semi steel protective device. The toughness is very good. When the vehicle hits, it can make a smooth country and force the vehicle to return to the normal route.

6. It can reduce the damage caused by the impact to the driver. The national highway guardrail post has good toughness and is not easy to break. When it is hit, the vehicle can be stopped by the deformation of the wave guard plate. The buffer force is very good and the accident caused by the damage can be reduced.

7.The highway guardrail post has a non negligible advantage that allows the driver to see the road edge line, and the effect of the guardrail is very good at night, and the driver is very easy to discern the road direction in the light of the light.

8.Both the highway guardrail post and the cable guardrail are the protective products of the freeway. They are basically similar in function and protection, but they have their own shortcomings and advantages. There is no single protective equipment on the freeway, so it is necessary to combine them so as to better protect the expressway and the safety of expressways.

highway guardrail post introduce

In our country, about 10 million people die from traffic accidents every year, causing about 20000000000 of the direct economic loss. Facing this trend, it is particularly urgent to strengthen the road safety. In spite of the failure to avoid accidents, the highway guardrail post of the expressway can at least reduce the casualties. The galvanized barrier can change the direction of the vehicle in a runaway state when it collides, and make it back to the normal track to avoid the vehicles running out of the freeway, thereby ensuring the safety of the vehicles and passengers to a certain extent, and reducing the loss of the accident.

The reason is that the highway guardrail post has excellent crashworthiness and absorptive properties, can absorb the impact force effectively, so it can play the role of protection; if the galvanized fence has broken place, it is also very convenient to move away, only need to pull out the column of the fence.

The galvanized highway guardrail post is a kind of structure which selects the guardrail plate with the shape of ripple, and plays the supporting structure. It has the ability of strong absorption and collision. It also has a good induction function and can be reflected with the road. It can be used in the small radius of the bend. As for the damaged area, it is also very convenient for maintenance. In addition, the galvanized fence has many advantages, such as good impact resistance, low cost, high safety performance, beautiful appearance, easy to install and easy to install. It is widely used in Expressway and is used for isolation.

Protection effect: the collision prevention grade of cable guardrail and highway guardrail post has its own level of protection: A, B and S, but the protective effect of the cable guardrail should be obviously better than the barrier board. The cable guardrail cable is composed of several wire rope, and the collision and self recovery of the wire rope are very strong. The guardrail plate is made up of corrugated steel plates, which can absorb the impact force of the vehicle well. However, the self restoring ability is poor, and the guardrail plates after impact need to be replaced.

Anticorrosion: there are many kinds of anticorrosion methods of cable guardrail and guardrail, but basically after hot galvanizing. The corrosion resistance of hot galvanized products is very excellent. It can be used normally for several decades in outdoor conditions. Therefore, the corrosion resistance of the two kinds of road protection products is very good.
