PRIMARY STUDY FOR NECESSARY WIDTH OF ICICLE PREVENTION WORK BY ADIABATIC TREATMENT OF TUNNEL SURFACE

In the past, ice forming in tunnels was removed manually. A new method has been developed in which the heat insulating material is sprayed directly or indirectly on the surface of the lining, and by reducing the release of geothermal heat as far as possible, the lining is kept warm. Some useful data has already been obtained although the tests have not yet been completed.
