What methods should be used for pavement cleaning of expressways and first-class highways?

Road sweepers are mainly used for mechanical cleaning of expressways and first-class highways.

Mechanical cleaning equipment usually used for road cleaning:

1, road sweeper (road sweeper)

Road sweeper is a kind of motor vehicle specially used for road cleaning. Equipped with rotating brush, vacuum cleaner and garbage collection system, it can effectively clean the garbage, dust and sundries on the road surface. The sweeper has efficient and fast cleaning ability, and is suitable for cleaning roads, bridges and other large areas.

2, high pressure water car wash (car cleaning)

High-pressure water car wash uses high-pressure water to clean the road surface, which can effectively remove stains and oil stains. It is usually equipped with a nozzle and water pump system, which can spray high-pressure water onto the road surface for cleaning. High-pressure water car washing is suitable for dealing with stubborn stains and dirt that are difficult to remove on the road.

3. Grinder

Grinding machine is a kind of equipment that grinds the road surface by rotating a metal disc. It can remove the attachments on the road surface, level the uneven road surface and improve the smoothness and friction coefficient of the road surface. Grinding machine is usually used to repair damaged pavement, polish the surface and increase the adhesion of pavement.

4. Vacuum cleaner

Vacuum cleaner is a kind of equipment specially used to remove dust, garbage and sundries on the road surface. Equipped with high-power dust collection system, the dirt on the road surface can be sucked into the collection box to keep the road surface clean. Vacuum trucks are usually used to clean small areas such as roads, sidewalks and squares.

Matters needing attention in mechanical road cleaning:

1, safe operation

Operators should receive relevant training and have professional knowledge and skills in using cleaning equipment. Make sure they are familiar with the operation methods and safety regulations of the equipment, and wear personal protective equipment correctly, such as helmets, gloves and earplugs.

2. Traffic management

During the cleaning operation, necessary traffic management measures should be taken to ensure the traffic safety in the construction area and surrounding areas. Set warning signs, cones and other equipment to guide vehicles to bypass or slow down to avoid traffic accidents.

3. Selection of cleaning time

Try to choose the time with less traffic to clean up, so as not to affect the smooth flow of road traffic. If cleaning must be carried out during peak hours, traffic control and guidance should be done in advance to ensure the coordination and safety of the construction area and traffic.

4. Environmental awareness

Garbage and waste generated in the cleaning process should be properly handled to avoid environmental pollution. Garbage should be collected in designated containers or garbage bags and disposed of properly. Chemicals or hazardous wastes shall be classified, packaged and treated according to relevant laws and regulations.
