IPC: F17C13/08
Filed: 1990-09-13
Abstract: PURPOSE:To rigidly fix the title structure within a ground by installing a plurality of anchors each having the lower end fixed within a lower ground of a bottom plate, and rigidly connecting the upper end of each anchor within the bottom plate. CONSTITUTION:A plurality of anchors 6 are buried within a lower ground of a bottom plate 3 of an underground type storage tank structure to a specified depth in such a manner that the lower ends thereof are fixed within the ground E, and the upper ends thereof are connected with the bottom plate 3.
