w-beam highway guardrail

w-beam highway guardrail

w-beam highway guardrail produced by our company meets the American Standard, which can be used to protect pedestrians' safety and let the vehicle return to the normal running track.

Highway is the high incidence area of traffic accidents, we see the news basically every day can see the occurrence of traffic accidents on highway, as the w-beam highway guardrail is often affected, then how to change the w-beam highway guardrail after the collision damage?

First we unload the damaged w-beam highway guardrail and check whether the nearby w-beam highway guardrail and post are damaged, and sometimes we can't check it with the naked eye. This is what we need to test by a professional tool.After unloading the damaged w-beam highway guardrail, we need to install a new w-beam highway guardrail. When we install it, we need to make a perfect splice to ensure the impact grade coefficient so that the protective effect can be achieved. If the post is damaged, we need to replace the post. After burying the post, we should compacted the soil as much as possible and ensure that w-beam highway guardrail not lower than the previous road surface.

Finally, it is necessary to cover the rain cap of the post. It is easy to overlook the daily maintenance of w-beam highway guardrail, and feel that it is irrelevant. In fact, the daily maintenance of w-beam highway guardrail is very important. If the w-beam highway guardrail is likely to lead to serious reflection of traffic accidents, originally protection products has become the hidden danger of accident, this is a violation of the protection of the mind, so the maintenance of w-beam highway guardrail should pay attention to it, reduce the reflection of w-beam highway guardrail.

With the improvement of safety, we must have a good understanding of the w-beam highway guardrail. The w-beam highway guardrail is a highway anti-collision facility. It is mainly to prevent out of control vehicles from running out of the road. It is usually made of galvanized steel plate. Different specifications are adopted according to different guardrail grades. Good protection. When the pavement maintenance or other reasons need and pass, it is convenient to pull out the columns at the opening, open up the channel, and facilitate the vehicle to pass through.The system principle of w-beam highway guardrail:

highway guardrail

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

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

3. The flexible steel phase of the wave beam guardrail has a strong ability to absorb the energy of collision. It has good 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.

w-beam highway guardrail has the advantages of good impact resistance, low cost, long life, high safety and environmental protection.

Notice on the construction of wave guardrail board:

1) the construction preparation should be adequate, and the location of pile numbers in construction sections should be accurately located. The setting out should be accurate and the error is within the specified scope.

2) column construction should be strictly and conscientiously, its perpendicularity, spacing, bolt hole location and other dimensions. Should meet the requirements, do not meet the requirements of immediate rework, at the same time, should be strictly in accordance with the specification JTJ074-94 rework.

3) the packaging and marking of components such as corrugated beam, column and so on should conform to the requirements of GB6725. The guardrail shall not be packed in bulk, and shall ensure that the product is not damaged or damaged during lifting, transportation and stacking. The transportation process should be fixed and reliable to prevent bumping and damaging the coating or deformation of the components.

4) the operation of guardrail should be prudent and not destroy the cable, pipeline and other facilities laid under the road surface.

The w-beam highway guardrail of market sales is soaked and sprayed. What is the difference between the two kinds of w beam highway guardrail? Which is better?

The production technology is the surface treatment process of the wave guardrail board, which is used to adsorb the plastic powder to the surface of the wave guard plate by static electricity, then the baking flow is flat, and the coating is thinner than the dipped plastic, but the adsorption force is strong. The impregnated plastic guardrail is to melt the plastic powder at high temperature, then soak the wave guard plate into the melted plastic powder, and then solidify into a film after cooling to form a thick layer of plastic like coating.

1. The dipping plastic is based on the wave guardrail, and the weatherproof polymer resin is its outer layer. It has the characteristics of anticorrosion and rust prevention, acid and alkali resistance, moisture proof, insulation, aging resistance, good hand feeling, environmental protection, long life and so on. It is the renewal and replacement surface treatment technology of the traditional antirust paint and galvanized coating.

2. The sprayed wave barrier is sprayed on the surface of the fence with an electrostatic spray machine. Under static electricity, the powder will be evenly adsorbed on the surface of the corrugated fence to form a powdery coating. The powder coating becomes the final coating with different effects after the high temperature baking. The effect of the spray is on the mechanical strength. Aspects, adhesion, corrosion resistance, aging resistance and other aspects are superior to the spray painting process, and the cost is also under the same effect of spray painting.

At present, China has become the largest automotive market in the world and is growing at a rate of 40% per year. The convenience that the car brings to people's life is beyond doubt, but the traffic jam is becoming more and more serious at the peak of the rush hour. The queuing phenomenon of vehicles entering and leaving the district and the office building is more and more common. In this regard, many parking managers began to take the car parking system represented by the license plate recognition instead of the traditional card parking system, in order to eliminate the trouble of parking management.The characteristics of traditional parking lot:

1, you must stop and brush your cards

2, it is easy to get wet in rainy days

3. Parking on the top and bottom ramps can cause accidents such as car slipping and collision. With the continuous development of the national economy in recent years, with the rapid development of the national economy and the sharp reduction of vehicles, the number of private cars in our country has increased rapidly. Almost all of the metropolises have been filled with no exception. It is difficult to find a parking space, which has prompted the domestic intelligent parking management industry to rise. In the past few years, the intelligent management technology of parking lots in our country is still blank. In order to get rid of this situation, the relevant departments have taken corresponding measures and formulated a long-term development plan, laying a solid foundation for the intelligent management of the parking lot in China, and the rapid development of technology has been obtained. The development of intelligent parking lots in China is getting better and better. "New parking lot project" and "car park renovation and upgrading project" are also increasing, and the number of opportunities is close to the monitoring project.

4, it is easy to cause traffic jam during the peak period

5, long distance reading cards need to add external equipment
