END STRUCTURE OF RADIOACTIVE WASTE DISPOSAL TUNNEL, MANUFACTURING METHOD FOR END STRUCTURE OF RADIOACTIVE WASTE DISPOSAL TUNNEL, AND LEAKAGE PREVENTION METHOD FOR MATERIAL CONFINED IN RADIOACTIVE WASTE DISPOSAL TUNNEL
To provide a plug periphery structure for more reliably preventing leakage of a material confined in a tunnel space formed with a plug and a tunnel from the inner part of tunnel space to the outside, a manufacturing method for plug periphery structure, and a leakage prevention method for material confined in the tunnel space.SOLUTION: A radioactive waste disposal tunnel for fixing radioactive waste inside is formed underground and includes an end structure 10. The end structure 10 of the radioactive waste disposal tunnel includes: two plug 12-1 and 12-2 installed at prescribed interval in an end of a tunnel 18 in which radioactive waste 4 is fixed; a region between plugs 16 filled with cutoff material slurry 14; a tunnel periphery impregnating region 22 impregnated with the cutoff slurry 14 from a perimeter surface of inner wall 18a of the tunnel 18 on region between plugs 16 to a tunnel periphery base rock 5.SELECTED DRAWING: Figure 1
【課題】栓体（プラグ）と坑道とで形成される坑道空間内部から、該坑道空間内に閉じ込めた物質の外部への漏洩をより確実に防止し得る栓体周辺部構造、栓体周辺部構造の製造方法及び坑道空間内に閉じ込めた物質の漏洩防止方法を提供すること【解決手段】地中に形成された、放射性廃棄物を内部に定置するための放射性廃棄物処分坑道の端部構造１０である。放射性廃棄物処分坑道の端部構造１０は、放射性廃棄物４が定置される坑道１８の端部に所定間隔をおいて並べて設置された２個の栓体１２−１，１２−２と、止水材スラリー１４が充填された栓体間領域１６と、栓体間領域１６における坑道１８の内壁１８ａの全周面から坑道周辺岩盤５へと止水材スラリー１４が含浸した坑道周辺含浸領域２２と、を含む。【選択図】図１
