PREVENTING SEEPAGE IN RAILWAY TUNNELS
During excavation the amount of water seepage in some places amounted to as much as 325 liters/sec. At first, trials were carried out to fill in the rock fissures by means of silicate injection, but finally a decision was made in favor of a new method of protection, using prefabricated concrete sections to form a primary arch. These reinforced sections have a width of 1m and thicknesses of 20cm at the apex and 40cm at the base. Two sections form an arch.
