CONSTRUCTION SCHEME OF GROUP OF UNDERGROUND WORKINGS FOR INSTALLATIONS OF RADIATION PART OF UNDERGROUND NUCLEAR POWER PLANT LOCATED PERPENDICULARLY TO DIRECTION OF MOUNTAIN INLAND Russian patent published in 2018 - IPC E21D13/00 

FIELD: construction.

SUBSTANCE: invention relates to scheme for constructing group of excavations for installations of radiation part of underground nuclear power plant perpendicular to direction of mountain inland. This scheme contains outputs (1) for installation of nuclear reactor, two combined outputs, two outputs (2) for installation of electrical equipment, two outputs (7) for pressure relief, transport tunnel (13) from branches, lateral transport tunnel (14), first main transport tunnel (8), second main transport tunnel (9) and third main transport tunnel (10). All the first main transport tunnel, the second main transport tunnel and the third main transport tunnel communicate with earth's surface. Developments for nstallation of nuclear reactor, combined outputs, production for installation of electrical equipment and production for pressure relief form group of underground workings for installations of radiation part of nuclear power plant. Upper arch heap or end wall of upper arch of each output in group of underground excavations for installations of radiation part of nuclear power plant communicates with earth's surface through upper level of system of branching tunnels. Lower parts of side walls of each generation in group of underground outputs for installations of radiation part of nuclear power plant are connected to first main transport tunnel, the second main transport tunnel and the third main transport tunnel through lower level of branching tunnels system.

EFFECT: scheme for construction has short distances, satisfactory safety and high degree of modularity, it is convenient for construction and saves investments.
