FIELD: construction.

SUBSTANCE: hydrotechnical deferent tunnel with reinforced concrete lining is designed as a working 1 in the rock with a cross section in the form of a figure of a constant width and in contact with the bearing reinforced concrete lining 2 with the external and the internal surfaces made in the cross-section in the form of a figure with a constant width. The cross-sections of the working 1, of the external surface in contact therewith, and of the internal surface of the reinforced concrete lining 2 are made in the form of a Reuleaux triangle. One of the coinciding corners 3 of the Reuleaux triangle of the working 1, the external and internal surfaces of the reinforced concrete lining 2 is located in the vault portion 4 of the tunnel with the reinforced concrete lining.

EFFECT: increasing the strength, stability and reliability of the hydrotechnical deferent tunnel in complex engineering geological and seismic conditions.
