There are many specifications of corrugated guardrails, and choosing the right corrugated guardrail can not only play a protective role, but also save some unnecessary costs. The following corrugated guardrail manufacturers will introduce the selection criteria of corrugated guardrails in detail:
1. Comprehensive consideration.
In the early design of high-speed corrugated guardrails, road conditions, traffic conditions, and traffic management conditions should be considered. At the same time, designers should be familiar with the road environment, especially the route design, traffic process, traffic safety and road traffic management, the origin of standards and specifications, the concept of the whole life cycle, and understand the situation of each stage of road construction, use and maintenance, so as to meet the use requirements to a certain extent in the design and ensure good design.
2. Adapt measures to local conditions.
Road design indicators. In particular, the linear shape and other indicators in the design of the car body, and then estimate the vehicle speed according to the traffic flow, so as to determine the initial collision conditions;
Roadside conditions, i.e., first determine the road hazard, and then select the corresponding level of waveform according to the hazard;
Accident rate, i.e., the selection of corrugated guardrails based on existing accident data;
Coordination with other traffic management departments. At present, urban road traffic management, the determination of speed limit indicators, the management of facilities such as sign markings, markings, etc., are the responsibilities of the traffic management department, and the management of the corrugated car, is the responsibility of the highway management department, therefore, the designer should also understand the traffic management when carrying out the corrugated car design, and comprehensively consider the problems such as mutual cooperation with the mechanical and electrical systems such as monitoring and communication.
3. Strong protection ability.
This means that the structure of the corrugated guardrail should have some compressive resistance. Don't get easily hit by a car. There is a lot of traffic on the urban road, and in the event of an accident. Because the economic loss is also very large, and it is easy to cause traffic congestion, so the corrugated guardrail can play a certain protective role, especially in the section of the road where the heavy truck passes through a large amount, such as the corrugated guardrail ** isolation belt, etc., the protection capacity is strong. It can avoid a secondary accident with an oncoming vehicle.
4. Good guiding ability.
After the vehicle collides with the corrugated guardrail, it can be discharged smoothly and will not be too large, resulting in a secondary accident of the vehicle.
5. Good economy and land saving.
At the same time, the amount of corrugated substrate is reduced as much as possible, and the guiding effect is ensured under the premise of satisfying the anti-collision guiding performance of corrugated substrate. In addition, China's land resources are scarce, especially in the city, so we should try to choose a wavy corridor with a small footprint, which not only saves space, but also reduces the cost of the project.
6. Beautiful appearance.
The corrugated guardrail should be in harmony with the surrounding environment of the road, and the corrugated guardrail can be beautified through greening.
7. Easy maintenance.
After an accident, if the corrugated guardrail can be repaired in a short time, the impact on traffic can be reduced, and traffic congestion can be avoided or reduced, so it is also important to maintain it simply.
