Description

Anti-glare isolation net corner protector for highway

Technical Field

The utility model relates to a capital construction facility field, concretely relates to highway anti-dazzle mesh separation net angle bead.

Background

Generally, a highway can accommodate speeds of 120 km/h or more, and the road surface has a width of 4 (inclusive) lanes or more. The middle is provided with a separation belt, adopts asphalt concrete or cement concrete high-grade pavement and is provided with complete marks, marked lines, signals and lighting devices; the pedestrians and the non-motor vehicles are prohibited from walking on the road, and the pedestrians and the non-motor vehicles are allowed to pass through the road by adopting the flyover crossing and the pedestrian overpass bridge or the underpass with other lines. By definition, a highway should generally meet the following 4 conditions: (1) only the automobile can run at high speed; (2) the device is provided with a plurality of lanes and a central separation belt, which completely separate the back-and-forth traffic; (3) a three-dimensional intersection is arranged; (4) the whole line is closed, the entrance and the exit are controlled, and only vehicles enter and exit the road at specified three-dimensional intersections.

An anti-dazzle net for expressway (anti-dazzle net plate) is a kind of metal screen. Also named as metal net, anti-throwing net, iron plate net, metal expanding net, punching plate, etc. As the name implies: the metal plate is formed into a mesh-like stretched material after being subjected to special machining treatment. Can effectively ensure the continuity and the transverse visibility of the anti-dazzle facility, can isolate the up-down traffic lanes, achieves the anti-dazzle and isolation purposes, and is a very effective express way guardrail net product. The net is made up by welding steel plate net, special pipe, side lug and circular pipe, and the connecting accessories are fixed with hot-dip plated pipe support. The anti-dazzle performance is excellent, and the anti-dazzle agent is mainly used for roads, expressways, railways, bridges, construction sites, districts, factories, airports, stadium green lands and other areas and plays a role in anti-dazzle and protection; in addition, the names of anti-dazzle isolation grids, fences, net fences and the like are provided; has the characteristics of beautiful appearance and less wind resistance.

A screen plate needs to be additionally arranged on a separation zone (also called as an isolation zone) in the middle of the highway, and the main function is to prevent dazzling; because the highway is an adjacent bidirectional through-flow lane and the driving speed is extremely high, a driver can select to turn on the high beam at night to make the driver look farther, so that more emergency response time can be realized in case of emergency; the use of the high beam can seriously affect the visual range of the oncoming traffic, so that an anti-glare mesh plate needs to be arranged on the separation belt, and the arrangement of the anti-glare mesh plate is very important for safe driving.

The anti-dazzle net plate of the central isolation belt of the expressway deforms and falls off after weathering, rainwater and a snow melting agent all the year round, particularly, the frequency of the edge of the lower part of the net plate is higher, the falling off of the anti-dazzle net plate not only influences the road appearance, but also influences the driving safety, and particularly for the driving safety, once the fallen net plate is blown to the road surface of the expressway by wind, great potential safety hazards exist.

In conclusion, the service life of the conventional anti-dazzle net plate is short, and once the anti-dazzle net plate is damaged, the anti-dazzle net plate needs to be found and replaced immediately, which has certain difficulty and mainly cannot be found in time; secondly, the short service life means that the replacement frequency is high, which can generate high maintenance cost of the expressway.

Therefore, the development of a structural member capable of prolonging the service life of the anti-dazzle net plate is very necessary for reducing the potential safety hazard of road traffic and the maintenance cost.
