How to apply the road blasting machine in tunnel construction?
Traffic accidents occur frequently in highway tunnels, and the anti-skid effect of tunnel pavement can be improved by using the pavement shot blasting machine to deal with them. The pavement 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 option for anti-skid treatment of highway maintenance tunnel.
In China, cement concrete is generally used for the pavement in tunnels due to the consideration of waterproof, fire and oil resistance of materials. However, it also puts forward higher requirements for the anti-sliding performance of long tunnel pavement. For the above two problems that are still difficult to solve in China, the road shot blasting machine is a treatment method with simple construction, small equipment investment, significant effect and environmental protection. The periodic cleaning of the tunnel pavement with the pavement blasting machine can greatly improve the reduction of the friction coefficient of the pavement due to pollution and tire marks, greatly improve the skid resistance of the tunnel pavement, and significantly reduce the accident rate. It can also be applied to road cleaning at toll stations and intersections.
Characteristics of road surface shot blasting machine
1. It is conducive to environmental protection and conforms to the principle of green construction.
2. The construction quality of the waterproof layer has been improved, and the service life of the bridge has been improved. The economic and social benefits are obvious.
3. In addition to the bridge deck pavement, the shot blasting process can also expand the application scope and be applied to the concrete works that ensure the combination effect of new and old concrete, such as the shot blasting treatment on the concrete structure surfaces such as tunnels, channels, approach slabs, etc.
The road surface shot blasting machine produced by Qingdao Runfang Machinery Co., Ltd. is an environmentally friendly product specially developed for various road construction and maintenance. This road surface shot blasting machine can achieve dust-free, pollution-free, and automatic recycling of shot materials during construction operations.
