highway guardrail fencing design

highway guardrail fencing is an important traffic facility. It is used for road safety guardrail. highway guardrail fencing is also called municipal guardrail. It is divided into different kinds according to different materials.

highway guardrail fencing can not only isolate lanes, but also divide traffic and flow. Reasonable planning and design can improve the overall transportation level of the road. At the same time, it can also ensure the safety of vehicles and pedestrians. What are the factors to be considered in the design and construction of highway guardrail fencing?

1.the first is the service life of the highway guardrail fencing. Generally, the iron road guardrail will deposit a layer of zinc material to the guardrail, and zinc has good anticorrosive and moisture-proof and anti soiling performance.

The highway guardrail fencing is the beautification and protection facilities on the outer edge of the balcony, which is welded or assembled by alloy pipes. The common low window sills are about 0.5 meters away from the ground. If guardrails or fences close to the inner walls increase by 0.4 meters, the protective measures must meet the standard requirements. If the desk of the window sill is too large, such as the convex window, the child often stands on the windowsill, and the user also has to stand on the window sill to open the window. At this time, the guardrail itself attached to the windowsill should be 0.9 meters high. The highway guardrail fencing is a guardrail set on the bridge.

The purpose is to prevent the out of control vehicle from beyond the bridge, which has the function of making the vehicle unable to break through, pass through, cross the bridge and beautify the bridge building. This can effectively protect the main body of the guardrail and improve the use time of the road guardrail (also known as the municipal guardrail).

　2. then the highway guardrail fencing color problem, the highway guardrail fencing also called the municipal guardrail color can remind the travel vehicle, help it to identify the guardrail's intention is what, the commonly used guardrail color generally red, yellow, white, blue and black five kinds, guardrails through the color combination of various other transportation facilities, remind the driving Safe driving. The lawn guardrail lets the homeland, let the city, let us live the place more beautiful, is more beautiful. And it has many bright colors.

3.Finally, the structure of the highway guardrail fencing also known as the municipal guardrail is designed. The road guardrail is assembled in the structure, so that even if a section of the guardrail is damaged, a new barrier can be quickly replaced to minimize the impact on the normal driving of the road. The lawn guardrail lets the homeland, let the city, let us live the place more beautiful, is more beautiful. And it has many bright colors.

　The above is the factors that need to be considered in the design of the highway guardrail fencing also known as the municipal fence, and I hope it will help you. The most important traffic infrastructure of highway guardrail is developed from 80s in China. It has played an important role in the development of the national economy and society. It is an important maintenance and safety guarantee facility for expressways. Now some roads use grassland fence net, and the twisting and weaving of grassland net is more robust, beautiful, economical and practical.

highway guardrail fencing install

For the highway guardrail fencing to improve (installation efficiency, first of all, you need to insert the vertical bar into the cross bar, the whole block is assembled and installed, and then the whole block is fixed to the fence. The lawn guardrail lets the homeland, let the city, let us live the place more beautiful, is more beautiful. And it has many bright colors. The Beijing guardrail separates the vehicle, non motor vehicle and pedestrian traffic, divides the road on the section longitudinally, makes the motor vehicles, non motor vehicles and pedestrians run apart, improves the safety of the road traffic and improves the traffic order. The bridge guardrail is a guardrail set on the bridge.

The purpose is to prevent the out of control vehicle from beyond the bridge, which has the function of making the vehicle unable to break through, pass through, cross the bridge and beautify the bridge building. River guardrail refers to the industrial "fence". Guardrail is mainly used for protection and protection of personal safety and facilities and facilities in residential, highway, business district, public places and other occasions. The guardrails are seen everywhere in our lives. The fence will vary according to the height, and the price per metre will also be different. Traffic barriers are a kind of traffic safety facilities installed on the outer side of the shoulder, the traffic divider, and the pedestrian road teeth. The collision energy is absorbed by the autologous deformation or the climbing of the vehicle, thus changing the direction of the vehicle, preventing the vehicle from getting out of the way or entering the opposite lane, and minimizing the damage to the crew.

Now the highway guardrail fencing manufacturers have very many ways to assemble the fence. Some are locked up and down with the pin, and the wire is worn through the wire, and the stainless steel (stainless steel, stainless steel) is fixed. The fastest installation is to first fix the bar on the pole and then insert the vertical bar, which will greatly improve the installation efficiency. It's more complex to assemble the whole and then to fix it. It takes a few people to control it, and it's not so convenient to install it for a long time. The retention of the column hole position is also very important, so that your bar is placed directly in the reserved hole, so that the post cement (material: powdery water rigid inorganic cementitious material) is sealed well. If it is made of tile or marble, the main time you install is to make holes, and it is easy to break the tiles and make it difficult to please.

road crash barrier

Therefore, experienced installers will be able to co-ordinate with the constructor so that they save a lot of things for themselves. So there are two main aspects. One is the way to assemble the chip, the other is to fix it to the post. highway guardrail fencing has its own installation steps step by step, it is also conducive to efficiency improvement, it will not rush around. When installing connectors for zinc steel guardrail, do not use wooden bottles on the floor, and use wooden screws to connect with wooden floors. According to the principle of three points to one plane, the expansion snail of the fixed connector can not be on the same line and can be as large as possible to enhance the stability of the connector (Interpretation: stable stability; no change); the combination of the column and the connector must be firm and tight without pores.
