What are the main functions of urban traffic guardrails?

Road guardrails are "traffic policemen" who never off. The design of the color function, structural safety and coating performance of the road guardrail is a set of systematic and complete technical solutions, which can comprehensively solve the various problems existing in municipal transportation and fully realize the functions and functions of municipal transportation. On the basis of no additional investment, the use of special road guardrails can not only play a role in isolation, guidance, protection, and aesthetics, but also will maintain traffic order, ensure traffic safety, enrich traffic language, beautify the road environment, and brighten the appearance of the city.

High-quality road guardrails with eye-catching signs, warning guidance, safety and reliability, corrosion resistance and corrosion resistance, and easy installation and maintenance can not only maintain traffic order and ensure traffic safety in urban traffic construction such as "smooth project" and "safe avenue"; It can also play the role of the finishing touch for the beautiful city appearance, add a beautiful urban landscape to the city image, enhance the degree of urban civilization, and thus improve the taste of the city.

Road guardrails are currently one of the most popular road isolation guardrails at home and abroad. It is mainly used for site isolation belt, municipal engineering isolation belt, and garden guardrail. Isolation and protection of parks, lawns, zoos, ponds, lakes, roads, and residential areas in municipal construction; Protection and decoration of hotels, hotels, supermarkets and entertainment venues.

Beautiful appearance: white, blue, red, green and other colors, bright colors, smooth surface. Safe, environmentally friendly, harmless to humans (animals).

The surface is smooth, the feel is delicate, the color is bright, the strength is high, the toughness is good, the domestic first-class raw material is selected, even if it accidentally touches the guardrail, it will not hurt people like steel and iron guardrails. Anti-aging test: no fading, no cracking, no embrittlement when used at -50 to 70 years, up to 30 years.

Maintenance-free: no decay, no corrosion, no fading, no need for daily maintenance, no pollution to the environment.

Easy to install: Installation with patented wipe-type connection or proprietary connection accessories for quick and easy fixing. The urban traffic guardrail is not only a simple isolation of the road, but also a key purpose is to clearly indicate and transmit urban traffic information to the traffic flow and establish a traffic rule and maintain traffic order, so that urban traffic can achieve a safe, fast, orderly, smooth and convenient effect.

Steel urban traffic guardrail guardrail since 2006 often appears in the requirements of each ** bidding, so the use of a wide range, mainly 3 kinds, one is the Beijing guardrail also called B-type guardrail, M-type guardrail. With the transformation of urban infrastructure, the competition in the urban guardrail market is becoming increasingly fierce, and there are two deformations of the conventional special-shaped pipe light guardrail, one is the anti-glare S piece urban guardrail, and the other is the anti-glare diamond-shaped urban guardrail. Plastic steel urban traffic guardrail.

According to the material specifications, it is divided into large plastic steel and small plastic steel.

Separation function: the traffic guardrail separates motor vehicles, non-motor vehicles and pedestrian traffic, and separates the road longitudinally on the cross-section, so that motor vehicles, non-motor vehicles and pedestrians drive separately, improves the safety of road traffic, and improves traffic order. Blocking function:

Traffic barriers will deter undesirable traffic behaviour and stop pedestrians or bicycles or motor vehicles trying to cross the road. It requires the guardrail to have a certain height, a certain density (referring to the vertical fence), and a certain strength. Alert function:

Through installation, the outline on the guardrail should be concise and bright, and the driver should be warned to pay attention to the existence of the guardrail and pay attention to pedestrians and non-motorized vehicles, so as to prevent traffic accidents. Aesthetic function: through different materials, different forms, different shapes and different colors of the guardrail, it can achieve harmony and coordination with the road environment.

Road guardrails are mainly used for the protection and protection of personal safety and equipment and facilities in residences, highways, commercial areas, public places, new rural construction and other occasions, and guardrails can be seen everywhere in our lives.

According to the material classification of guardrails, there are iron guardrails, stone guardrails, PVC guardrails, wooden guardrails, cement guardrails (concrete cement imitation wood railings, imitation stone guardrails, imitation bark railings, imitation bamboo guardrails), plastic steel guardrails, stainless steel guardrails, glass guardrails, etc.

According to the function and use of guardrails, there are community guardrails, villa guardrails, anti-theft guardrails, stadium guardrails, etc.

According to the decorative characteristics of the guardrail, there are artistic guardrails, wrought iron guardrails, perspective guardrails, fence guardrails, American-style guardrails, European-style guardrails, etc.

According to the appearance classification: bilateral wire fence mesh, frame fence mesh, double ring fence mesh, Meige mesh guardrail, hook mesh guardrail, steel mesh guardrail.

There are mainly highway fence nets, railway fence nets, airport fence nets, garden fence nets and so on. According to the type, there are mainly the following types of fence nets, and the following is a brief introduction to their characteristics. Plugging and unplugging fence mesh, mainly used in the highway, its structure is mainly composed of two parts, the upper and lower column steel pipes, one part of which is sleeved on the other part, and there are bolts connected inside, which play a fixed role.

This kind of guardrail is beautiful and easy to install, which is very suitable for the protection of gardens, roads, temporary isolation belts, etc.; Wrought iron fence mesh, the characteristics of this fence mesh are mainly simple and practical structure, easy to transport, bendable, suitable for uneven areas, cheap, suitable for large-area applications; Frame fence net, installation is very flexible, generally used for the protection of various road peripheries, the installation mode of this fence can be changed, therefore, can be used as a long-term guardrail application, can also be used as a temporary guardrail. Because of its easy installation, durability and sturdiness, this kind of guardrail is a very inexpensive guardrail wall, and is now widely used in various regions of various countries. There is also a kind of warehouse isolation fence, its main purpose is to distinguish the items between warehouses or inside the warehouse, which occupies less space and has good protection performance is its biggest benefit and advantage.

The first is the blocking function of the corrugated guardrail. Traffic barriers will deter undesirable traffic behavior and deter pedestrians, bicycles, or motor vehicles trying to cross the road. It requires a guardrail board of a certain height, a certain density (referring to the vertical column) and a certain strength.

Therefore, the guardrail plate can be applied to different Yanhui road sections according to different collision levels.

Separation function of guardrail panels. Traffic guardrail panels separate motor vehicles, non-motor vehicles, and pedestrians, and divide the road longitudinally on a cross-section, thereby separating motor vehicles, non-motor vehicles, and pedestrians. Safety improves traffic order.

Especially on highways, it can protect the surrounding pedestrians and other cattle, sheep and livestock animals that have strayed in.

The guardrail panel is now also a warning guide function. After the installation of the guardrail board appearance is smooth, brightly colored, concise and coarse, generous, and remind the driver to pay attention to the existence of the guardrail board, with a very good guiding effect, so that the driver can pay attention to pedestrians and non-motorized vehicles, in order to achieve the effect of preventing traffic accidents. It also has an aesthetic effect, with smooth lines that can make people feel comfortable while driving.

Through different materials, different forms, different shapes and different colors of the guardrail panels, harmonious harmony with the road environment can be achieved. Traffic barriers are more than just simple segregation of roads. The more critical purpose is to clearly display and transmit traffic information to people and vehicles, establish traffic rules, maintain traffic order, and make traffic safe, fast, orderly, smooth and convenient.

With the development of roads, road guardrails are also widely used, road guardrails not only protect the safety of people but also make the road smooth, it plays an important role in traffic safety as a basic safety facility in traffic. So what are the functions of guardrails on the road?

1. It can prevent the vehicle from driving off the road, or prevent the runaway vehicle from crossing the ** divider into the opposite lane. Sight guidance facility refers to a facility that allows the driver to drive the vehicle to judge the direction of the road outside the line of sight, especially at night, when it rains heavily, fogs, and there is snow on the road, etc., to induce the driver to correctly grasp the direction. Line-of-sight guidance facilities include contour markers, road buttons, and linear guidance markers.

2. The trajectory of the collision fence should be able to transition smoothly, so that the vehicle can return to the normal driving direction and reduce the possibility of secondary accidents. Isolated and enclosed facilities are mostly located on both sides of densely populated roads or livestock activities in towns and suburbs with highways, rural markets, villages and schools.

3. Once the runaway vehicle collides with the guardrail, it can reduce the damage to the driver and passengers. Isolation and closure facilities refer to the facilities that prevent people and animals from entering and crossing the highway at will, and prevent illegal occupation of highway land.

4. It can induce the driver's line of sight, and can clearly see the direction of the road and the contour of the road. Anti-glare facilities refer to artificially constructed structures that prevent driving at night from being glare from the headlights of oncoming vehicles. It is divided into slatted type, fan-shaped anti-glare panel, anti-glare net, anti-glare shed and other structural forms.

Anti-glare facilities are mostly located in the road sections with a high accident rate at night, and the traffic flow at night is large, especially the road sections with a high mixing rate of large trucks and small cars and the road sections with a small curve radius.

The urban road guardrail is not only a simple isolation of the road, but also a key purpose is to indicate and transmit urban traffic information to the traffic flow, establish a traffic rule, maintain traffic order, and make urban traffic safe, fast, orderly, smooth and convenient.

Guardrails play an important role in road traffic safety, effectively separating roadways and sidewalks, reducing the incidence of traffic accidents and ensuring the safety of pedestrians and vehicles.

A guardrail is a road traffic facility that is mainly used to separate roadways and sidewalks to avoid direct collisions between vehicles and pedestrians. The role of guardrails is not limited to this, it can:1

Protection of road facilities: Setting guardrails on highways, bridges, ramps and other road sections can prevent vehicles from deviating from the road or breaking through the guardrail and falling, thereby protecting the integrity of road facilities; 2.Guide the vehicle to drive:

Through the bucket setting of the guardrail, the vehicle can be guided along the correct road, and in some cases, it can also play the role of diversion; 3.Landscaping: Setting up beautiful guardrails can add a scenic line to the road and improve the aesthetics of the surrounding environment.

In China, the transportation department stipulates standards such as the height and material of guardrails that should be set on various types of roads to ensure the quality and safety of guardrails. At the same time, guardrails need to be set up to take into account the needs of pedestrians and vehicles to avoid unnecessary collisions caused by being too high or too low.

Under what circumstances may a guardrail lose its protective effect? A: Circumstances in which guardrails may lose their protective effect include, but are not limited to:

1.Guardrail damage: After a long time of use and wind and rain, the guardrail may be damaged in various ways, which needs to be repaired or replaced in time; 2.

Unreasonable design of guardrails: If the guardrails are set unreasonably, the height is too low or too high, it may lead to traffic accidents; 3.Road Reconstruction:

If the guardrail is not adjusted accordingly after the road is reconstructed, the original protective effect may be lost.

Guardrails play an irreplaceable and important role in road traffic safety, which needs to be reasonably set up and maintained in time to ensure road traffic safety and smooth traffic.

Legal basis]:

Article 62 of the Road Traffic Safety Law of the People's Republic of China Pedestrians passing through intersections or crossing roads shall take pedestrian crossings or street crossing facilities; When crossing a pedestrian crossing with a traffic signal, you should follow the instructions of the traffic signal; When crossing an intersection without traffic lights or pedestrian crossings, or crossing a road on a section without crossing facilities, you should pass through Kaisan after confirming that it is safe to do so.

According to the different stiffness, the form of the protective fence can be divided into three categories: Chishan flexible guardrail, semi-rigid guardrail and rigid guardrail.

Flexible guardrail generally refers to a ductile guardrail structure with a large ability to buffer nuclear denier bonds. It is a structure in which several cables with initial tension applied are fixed to the pillars, and it mainly relies on the tensile stress of the cable to resist the collision of the vehicle and absorb energy. Cables work within a flexible range and basically do not need to be replaced.
