FIELD: construction.
SUBSTANCE: invention relates to hydrotechnical construction and can be used in construction of underwater transport tunnels. Underwater tunnel comprises installed on supports underwater elongated watertight tunnel section with at least one cavity inside, herewith the opposite ends of adjacent tunnel sections are interconnected by connection means so, that longitudinal axes of all tunnel sections are aligned in the lengthwise direction. Tunnel sections are made from concrete, and the connection means are composed of pre-stressed ropes arranged inside walls of the tunnel sections along their lengthwise axis. Length of each rope exceeds the length of the corresponding tunnel section, and the ends of each rope are located in adjacent sections.
EFFECT: technical result is the increase of strength, stiffness and bearing capacity of the structure, reduction of material consumption of the structure.
