The w beam guardrail is an indispensable basic supporting facility on the highway, which plays an important role in playing the efficiency of the highway, preventing or even reducing the occurrence of traffic accidents.

Since our country began to repair highway in large numbers, pedestrians' awareness of all safety facilities has also been greatly improved. Our company's highway anti-collision safety facilities include guardrail plates, columns, ends, blocks, contour markers and screws.As a series of equipment such as snail, the guardrail is the main part of the road safety facilities.

His importance has gradually aroused people's attention. The technical standards of Highway Engineering in our country have the characteristics of our country. Because of the large population of our country, the land is precious, and the highway slope is taken out.The value is steep, that is, to a certain extent the increase of the risk factor of the road test, at this time the high-speed guardrail became an indispensable safety guard on the highway, and what parts of the security guard did it have?

There are several kinds of accessories for the crashworthy guardrail, including the column, the block, the crashworthy guardrail bracket, the ends, the columns, the rain cap and the bolts. The function of each accessory is very important. Lack of any component can not achieve effective protection effect.The specific role of each component is introduced.

High speed road crashworthy guardrail column can be divided into galvanized column, plastic column, flange column, ordinary column and so on. There are many kinds of columns, and according to engineering needs, we can map out suitable sizes and specifications. The highway crashworthy guardrail is fixed on the roadbed and combined with the roadbed.It is an integral part of the protective effect.

w beam guardrail belong to Processing industry and Metal material pressure processing.

The role of a column cap is also very important. If there is no column cap, rain or snow, there will be a lot of rain in the column. There are a lot of acid ions in the rain, even if it is a good antiseptic column, for a long time.It will not hold up, and it will corrode. In general, the resistance block and bracket will choose one, connecting the anti collision guardrail with the column, the protective effect of the resistance block is better than the bracket, the deformation of the resistance block is larger and the deformation of the parts is slowed down.The driving force of a car.

The use of the guardrail end is relatively small. Install one at each end of each guardrail plate, so that each guardrail plate looks more beautiful and beautiful.

High speed road crash barrier bolts, its corrosion resistance is very important, and good anticorrosive bolts can largely improve the service life of guardrail plates.

Guardrail pavement design is an important part of road design. The task is to determine the pavement grade, choose the type of road surface, design the structure combination, calculate the thickness of each structure layer and determine the mix ratio, so as to achieve good stability and sufficient strength when carrying various vehicle loads in different seasons and hydrology conditions, and take into account the speed and safety of traffic, road maintenance and good. Good economic benefits and other requirements are reasonable.

Rigid pavement design mainly refers to pavement structure design with cement concrete as pavement or base. Cement concrete has greater flexural strength and modulus.
