How is the road shot blasting machine used in tunnel construction?
Traffic accidents occur frequently in expressway tunnels. Using a road shot blasting machine to deal with them can improve the anti-skid effect of the tunnel road surface. The road shot blasting machine has the characteristics of low cost, simple operation process, low technical difficulty, strong operability and high efficiency, and can be used as the choice for anti-skid treatment of highway maintenance tunnels.
In my country, cement concrete is generally used for the road surface in the tunnel due to the considerations of waterproofing, fire resistance and oil resistance of the material. But this also puts forward higher requirements for the anti-skid performance of the long tunnel pavement. For the above two problems that are still difficult to solve in my country, the road shot blasting machine is a treatment method with simple construction, small equipment investment, remarkable effect and environmental protection. The use of road shot blasting equipment to periodically clean the tunnel pavement can greatly improve the reduction of the friction coefficient of the road surface due to pollution and tire marks, greatly improve the skid resistance of the tunnel road surface, and significantly reduce the accident rate. And it can be applied to road cleaning at toll stations, intersections, etc.
Features of road shot blasting machine
1. It is beneficial to protect the environment and conform to the principle of green construction.
2. The construction quality of the waterproof layer is improved, the service life of the bridge is increased, and the economic and social benefits are obvious.
3. In addition to the bridge deck pavement, the shot blasting process can also expand the scope of application, and be applied to concrete projects that ensure the combination effect of new and old concrete, such as shot blasting the surface of concrete structures such as tunnels, passages, and slabs.
The pavement shot blasting machine produced by chengdu shugong Machinery Co., Ltd. is an environmentally friendly product specially developed for various road construction and maintenance. This pavement shot blasting machine can be dust-free, pollution-free, and shot blasting during construction. Automatic recycling.
