    Abstract: PROBLEM TO BE SOLVED: To provide a cutting and dismantling method for cutting and dismantling a reactor from a lower part adjacent to a reactor core where radiation level is high while lifting upper part of a shielding wall of the reactor and a wire saw type cutting and dismantling apparatus used for implementation of the method.SOLUTION: The wire saw type cutting and dismantling apparatus includes: an U-shaped guide frame with an upper part opened wider than a thickness of wall of a large cylindrical structure for allowing a wire saw to run around on the guide frame, and the frame is arranged to perform auto travel in a longitudinal direction along a track. The wire saw runs crossing the U-shaped guide frame with an upper part opened horizontally, and the U-shaped part is arranged to perform parallel movement vertically. The wire saw type cutting and dismantling apparatus is carried in to a work floor and is disposed so that the upper opened U-shaped guide frame receives a lower end portion of the large cylindrical structure. The wire saw is driven to travel around the frame and perform vertical movement upward to cut the wall vertically as well as to cut the wall horizontally by moving the U-shaped guide frame along the track while maintaining the height of the wire saw, and subsequently, to perform a vertical cutting by shifting the wire saw downward to cut off the part of the structure.

    Abstract: PROBLEM TO BE SOLVED: To obtain a soil improvement structure which can restrain shear deformation from being caused by vertical motion of ground inside an underground wall, and which can suppress the liquefaction of the ground. SOLUTION: This soil improvement structure 10 includes: the underground wall 20 which surrounds the ground 12; a deformation inhibiting plate 22 which is arranged on soft ground 18, which is higher in rigidity than the soft ground 18, and which covers the inside of the underground wall 20; and a joint member 24 for filling the gap between an inner surface of the underground wall 20 and the deformation inhibiting plate 22. In this case, since a vertical load is transferred to the soft ground 18 via the deformation inhibiting plate 22 during earthquakes the effective stress of the upper layer of the soft ground 18 is increased to constrain the vertical motion of the soft ground 18. Additionally, since the rigidity of the surface layer of the soft ground 18 is enhanced than the soft ground 18 by the deformation inhibiting plate 22, a horizontal force is transferred to the underground wall 20 from the deformation inhibiting plate 22 via the joint member 24 during earthquakes. Consequently, the shear strength and liquefaction of the soft ground 18 can be suppressed. COPYRIGHT: (C)2010,JPO&INPIT
