CONSTRUCTION DIAGRAM OF UNITED GROUP OF UNDERGROUND NUCLEAR POWER PLANT PRODUCTIONS IN DIRECTION OF MOUNTAINS DEPTH

摘要

FIELD: construction.;SUBSTANCE: invention relates to scheme for construction of integrated group of excavations for underground nuclear power plant in direction of mountain depth. Construction scheme contains production (1) for working block of nuclear reactor, two combined workings, two outputs (2) for working unit of electrical equipment, two pressure relief workings (7), the first main transport trunk (8), the second main transport trunk (9) and the third main transport trunk (10), with three main transport trunks communicating with earth's surface. Production (1) for working block of nuclear reactor, combined outputs, production (2) for working unit of electrical equipment and production (7) of pressure relief form group of underground excavations for blocks of radiation part of nuclear power plant. Dome top supports or dome wall support of each production from group of underworkings for placement of radiation part of nuclear power plant are communicated with earth's surface through support system of production located in upper layer. Lower parts of side walls of each production from group of underground workings for blocks of radiation part of nuclear power plant are connected with three main transport shafts through production support system located in lower layer.;EFFECT: construction scheme has reduced area, high safety, it is convenient in construction, provides savings of investments, high degree of modularity and can be widely applied in construction engineering of nuclear power facilities.;7 cl, 3 dwg
