How to prevent the tunnel from slipping?
Tunnel pavement is a closed special bad environment. A large amount of dust, gasoline and engine oil are deposited on the pavement and attached to the pavement, greatly reducing the friction coefficient of the pavement. Therefore, improving the friction coefficient of vehicles arriving in the tunnel is the key to reducing tunnel traffic accidents. Then how to deal with anti-skid of tunnel pavement?
In China, the road surface inside the tunnel is considered to be waterproof, flame resistant and oil resistant. Cement concrete is generally used. At the same time, the skid resistance of the tunnel road surface is also highly required. The road surface shot blasting machine is a simple construction, small equipment investment, significant effect and environmental protection treatment method. The concrete surface treated by the road surface shot blasting machine can clean and remove the laitance and impurities on the concrete surface at one time. The most important thing is to roughen the concrete surface at the same time to make the surface rough and uniform, greatly improve the bonding strength of the waterproof layer and the concrete base course, and roughen the road surface, increase the roughness and friction coefficient of the road surface, improve the skid resistance, and ensure the safety of the road.
