How to prevent slippery shot blasting in the tunnel?
The road surface of the tunnel is a closed and special environment. A large amount of dust, gasoline, and engine oil are deposited on the road surface, and a large amount of it is attached to the road surface, which greatly reduces the friction coefficient of the road surface. Therefore, increasing the friction coefficient of vehicles in the tunnel can reduce tunnel traffic accidents. The essential. So how to deal with the anti-skid treatment of the tunnel pavement?
In our country, the pavement in the tunnel is considered in terms of waterproofing and material fire and oil resistance. Cement concrete is generally used. At the same time, the slip resistance of the tunnel pavement also has higher requirements. The pavement shot blasting machine is a simple construction and small equipment investment. An effective and environmentally friendly treatment method. The concrete surface treated by the pavement shot blasting machine can clean and remove the floating slurry and impurities on the concrete surface at one time. The most important thing is that the concrete surface is roughened at the same time to make the surface rough and uniform, which greatly improves the waterproof layer. The bonding strength with the concrete base layer, and the pavement can be roughened, which can increase the roughness and friction coefficient of the road surface, increase the anti-skid performance, and ensure the safety of the road.
