highway guardrail systems

highway guardrail systems introduce

The wavy guardrail is composed of two steel guardrail plates with wavy beams and two supporting columns fixed between them. The two supporting columns are fixed and clamped between two wavy steel guardrail plates. In the normal operation of the highway, the guardrail can be conveniently inserted into the pre-set jack-and-pull holes at the opening by using the plug-and-pull steel column, which plays a role of isolation and protection. At the same time, the guardrail corresponds to the guardrail belt on the outside of the highway and is uniform and beautiful. What is the principle of highway guardrail systems?

highway guardrail systems is the first form of semi-steel guardrail, it is a kind of interconnected and supported wave guardrail.

highway guardrail systems protector deforms subgrade, column and beam, absorbs impact energy, changes out-of-control direction of vehicles, restores normal driving direction, avoids vehicles rushing out of highway, and protects vehicles and passengers.

The guardrail steel plate is soft, highway guardrail systems has the strong absorption collision energy ability, has the good visual sensing function, may form the harmonious beautiful pavement and the circuit, may use in the small radius, the simple replacement. Traffic industry standard JT / / 281-2007 "highway wave guardrail".

The total length of the highway guardrail systems is 4320 millimeters (the remaining 4 meters at the end of the equipment), and the distance between the columns is 4 meters.

highway guardrail systems plays an important role in reducing accident severity, eliminating various vertical and horizontal disturbances, improving highway service level, providing landscape guidance, and improving road landscape. Research on the design and application of highway traffic safety facilities system has important practical significance for effectively solving highway traffic safety problems, rationally allocating social resources, and promoting the harmonious development of society.

highway guardrail systems advantage

Highway wave guardrail is China's most important transportation infrastructure. Since 1980s, the National High Since the development of expressway, it has played an important role in the national economic and social development, which is an important highway maintenance and safety protection facilities.

Hot-dip galvanized spray barrier has the advantages of waterproof, acid-proof, anti-corrosion, anti-aging, paint-free maintenance, etc. The thickness of galvanized layer is not less than 120 g per square metre, bright color, modern modeling, service life of more than 30 years.

Color diversification has changed the appearance of iron art fence single color. Hot-dip galvanized steel pipes on the guardrail surface have the functions of anti-corrosion, anti-rust, anti-ultraviolet radiation, anti-dirt and self-cleaning after surface treatment by electrostatic spraying technology. After being washed by rainwater spraying and water gun spraying, they can be as bright as new.

Inverted U-shaped iron fence is composed of N inverted U-shaped interconnected with two end columns and bottom horizontal support connection, usually cast iron base or prefabricated casting stable.

Inverted U-type iron fence is mainly used in the separation of municipal roads and highways, highway separation management and wall protection, pedestrian and motor Lane separation and other purposes.

Application of highway guardrail

In the parking lot management of Expressway anti-collision barrier, license plate recognition technology is also the main means to identify vehicles. In the Technical Requirements for Parking Vehicle Image and License Plate Information Collection and Transmission System, which is constructed by Shenzhen Public Security Bureau, license plate recognition technology has become the main means of vehicle identification. R & D for the convenience of parking management.

Vehicle license plate # code is the only "identity" sign of vehicle. Automatic license plate recognition technology can realize the automobile "identity" automatic registration and verification without any changes to the vehicle. This technology has been applied to highway toll collection, parking management, weighing system, traffic guidance, traffic law enforcement. Road inspection, vehicle scheduling, vehicle detection and other occasions. The parking lot management system has the characteristics of wiring and system linkage.
