The invention discloses a special tool for supporting upper deck combination of a semi-submersible type ocean platform. The special tool comprises supporting piers. Each supporting pier is formed by connecting standard joints upwards and the top of each supporting pier is provided with a top cover; each standard joint comprises four circular pipe uprights equal in height, transverse supporting pipes and inclined supporting pipes; the two ends of each circular pipe upright are provided with flanges. Connecting eye plates are further arranged right outside the upper end and the lower end of each circular pipe upright. The eye plates of every two partially-adjacent supporting piers at the same height are connected through transverse pull ribs. A walking bridge is arranged between the adjacent supporting piers at the same height through lap joint of supporting plates. The elevated piers are relatively easy to build and convenient to assemble, disassemble, transport and store. Part of the standard joints can be increased or decreased as required so that the requirements for different supporting heights can be met; more elevated pier sets can be expanded in the horizontal direction, so that the range of larger area is supported; meanwhile, the walking bridge connecting the elevated pier sets can be used as a work supporting platform for upper combination seam treatment.
