On the highway, the barbed wire protective net is generally used to prevent people and animals from crossing the highway at will, so as not to interfere with driving and reduce accidents, as well as effectively prevent illegal occupation of highway land and other issues of traffic safety facilities. There are many forms of barbed wire protective nets, commonly used are metal, woven nets, barbed wire and evergreen green gracilaria. In the densely populated areas set up metal woven net, people and animals are less sparse areas of the form of barbed wire, in the toll station, service area and other sections of the structure of hedge and barbed wire. In the past two years, considering the aesthetic problem, some highways in the Pearl River Delta region adopted the fruit plastic spot welding mesh (usually said guardrail mesh), the barbed wire protective mesh is more beautiful, but also durable, the overall effect is good, but the construction requirements are higher, more expensive. General sections should not be used, in the city center, scenic spots or strong requirements for beauty of the section available.
The specific design and layout principles are:
1. The center line of the barbed rope protective net is set within 20 to 50 cm of the road land boundary.
2. When there are channels, ponds, lakes and other natural barriers on the side of the road, there is no need to worry about people and animals entering and illegally occupying the road land.
3, the barbed rope protective net in the bridge, channel, should be in the direction of the bridge cone slope (or end wall), should not leave people, animals can drill into the gap.
4, barbed wire protective net and culvert intersection, such as the ditch is narrow, barbed wire barbed wire protective net can be directly crossed, the ditch is wide, barbed wire barbed wire protective net is difficult to cross, can take the treatment method of bridge, channel.
5, when the terrain is limited, the barbed wire barbed wire protective net before and after can not be set continuously, this is the end of the barbed wire protective net, and handle the end of the sealing.
6. The barbed rope protective net should be laid according to the terrain of the road boundary. The flat section should be set horizontally, and the slope section should be set along the slope or by the step form.
