How is the road surface shot blasting machine used in tunnel construction?
Traffic accidents in expressway tunnels occur frequently, and road surface shot blasting machines can be used to improve the anti-skid effect of tunnel road surfaces. The pavement shot blasting machine has the characteristics of low cost, simple operation process, low technical difficulty, strong operability, and high efficiency. It can be used as an option for anti-slip treatment of expressway maintenance tunnels.
In our country, cement concrete is generally used for the pavement inside the tunnel due to considerations of waterproofing, fire resistance and oil resistance of materials. But this also puts forward higher requirements on the anti-skid performance of long tunnel pavement. For the above two problems that are still difficult to solve in our country, the road shot blasting machine is a treatment method with simple construction, small equipment investment, significant effect and environmental protection. Using road surface shot blasting machine equipment to periodically clean the tunnel road surface can greatly improve 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 conforms 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 on the surface of concrete structures such as tunnels, passages, and slabs.
The road surface shot blasting machine produced by Chengdu Shugong Machinery Co., Ltd. is an environmentally friendly product specially developed for various road construction and maintenance. This road surface shot blasting machine can be dust-free, pollution-free, and abrasive during construction operations. Can be recycled automatically.
