highway guardrail products

The highway guardrail products is mounted on both sides of the highway to prevent vehicles from being hit out of the freeway because of out of control or in a car accident. highway guardrail products is a very mature road construction technology.

highway guardrail products is ready to be installed before construction. First of all, the project department should be set up. The project department is the core and core of the whole project.

The establishment and improvement of the construction system and the personnel management system are the necessary conditions for the safe construction and the civilized construction. Secondly, we should review the construction documents and determine the construction plan and progress, especially the requirements and safety awareness training for the construction personnel, clearly grasp the weather conditions and geological conditions in the construction area, do a good job in the long-term arrangement, and carry out the responsibility to the individual.

After that, the construction structure is tested and the pile can be constructed after being inspected by geological supervision engineers and technicians.

Material inspection. The inspection of materials should be conducted according to the relevant regulations. The main contents include whether the size, specification and process of materials are consistent with the notes of construction drawings.

Line up. First of all, it is necessary to find the standard point, to ensure that the position of each datum point is accurate, especially when the slope is larger and the curve stage should be set up the datum point, and the phenomenon of no dead angle without reference point is prohibited.

In the process of setting up the datum points, we should carefully check the exact location of the layout points, do well in record and knowledge, so as to facilitate the completion and acceptance. For the sections that are not in conformity with the construction drawings, the construction plan and the construction measures should be adjusted according to the situation, and the construction plan after the change should be examined after the inspection of the supervision unit.

Piling. Pile driving is the key to the construction of high speed guardrail. It is necessary to ensure the spacing, perpendicularity and accuracy of each pile, so that it can not only make up the position bias of the caving line, but also increase the overall stability and beauty of the guardrail after the construction.

The existing pile driving technology mainly includes two kinds of diesel piling and hydraulic pile driving. However, because of the large motor performance of the guide rod diesel piling, it is not easy to control. The destruction of the pavement and the loose condition of the slope often occur during the construction process, so the hydraulic piling machine has been replaced and widely used.

Barrier function of highway guardrail products: traffic barriers will obstruct bad traffic behavior and block pedestrians or bicycles or motor vehicles trying to cross the road. It requires a certain height of the guardrail, a certain density (a vertical column), and a certain intensity.

highway guardrail products is formed by the extrusion molding of automatic production line, the surface is clean and tidy and has no damage, the antisepsis is very strong, the surface treatment is mature, anticorrosion, anti aging, anti sun, high temperature, low temperature and so on. The service life of outdoor environment can reach many years.

The separation function of the highway guardrail products: the traffic barrier separates the vehicle, non motor vehicle and pedestrian traffic. The road is separated longitudinally on the section to make the motor vehicle, non motor vehicle and pedestrians run apart. It improves the safety of the road traffic and improves the traffic order.

Warning function: through installation to make the fence outline simple and quick, warn the driver to pay attention to the existence of guardrail and pay attention to pedestrians and non motor vehicles, so as to prevent the occurrence of traffic accidents.

Beautiful function: through the guardrail's different material, the different form, the different modelling and the different color, achieves the harmony and the coordination with the road environment.

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