Description

Technical Field

[0001] The invention relates to the technical field of road construction, and in particular to a buffer and anti-collision system for highway construction. Background Art

[0002] During road construction, for the sake of construction safety, some plastic traffic cones are usually placed in the road construction area to remind vehicles that there is construction ahead to avoid accidents. However, plastic traffic cones are small in size and are easily overlooked on the road. Drivers do not pay much attention to them, especially at night or in poor visibility. Special reflective treatment is required, otherwise their visibility will be greatly reduced, affecting their warning effect. In addition, plastic traffic cones have poor anti-collision ability. Once an accident occurs, vehicles are likely to rush into the construction area, endangering the safety of road construction vehicles and personnel.

[0003] Therefore, in view of the above problems, a highway construction buffer and collision avoidance system is proposed to solve the above problems. Summary of the invention
