FIELD: building, particularly underground structures built under difficult mining and geological conditions, namely in presence of soft watered grounds at tunnel base.
SUBSTANCE: tunnel comprises prefabricated lining including hollow metal members driven in ground and forming a screen, load-bearing frames and grouting concrete. Metal members are joined by means of locking means. At least some metal members driven in ground have constant outer diameters. At least part of above metal members are composed of sections having different lengths. Lengths of the metal members decrease in direction opposite to the driving direction.
EFFECT: increased reliability and operational safety due to prevention of original ground surface settlement during tunnel building and operation; prevention of ground settlement during tunnel building under traffic road without traffic interruption, reduced time of tunnel building, labor and power inputs, material consumption due to optimal material distribution along driven member in correspondence with loading of its sections.
