干冰清洗隧道的可行性研究

With the increasing number of the tunnel, the clean problem attracts people's attention gradually. This paper studies dry ice cleaning which is a new Tunnel cleaning methods puts forward a theory model of tunnel dry ice cleaning based on the phase transformation theory between the carbon dioxide and dry ice, and a dry ice cleaning method. Take experiment about feasibility of dry ice cleaning concrete. Cleanliness test results indicate that test equipment can be used in the experiment of concrete cleaning, the dry ice cleaning effect is obvious and is undamaged to concrete surface. Compared with other cleaning technology, dry ice cleaning technology possesses advantages, such as safety and efficiency. Analysis shows that dry ice cleaning technology is better than the other cleaning technology, and it apply to tunnel cleaning.
