PROBLEM TO BE SOLVED: To solve the following problem: in construction of a conventional drainage tank, a reinforced wall is formed in the construction field by arranging forms on the periphery of the drainage tank and placing concrete in order to avoid an effect of earth pressure load, and therefore not only complicated work procedures including concrete form arranging work, concrete transportation, concrete pouring work, and form removal work must be carried out but also a long construction period including a concrete setting time is spent. SOLUTION: There is provided a high-strength drainage tank which is formed by molding a drainage tank main body case made of a plastic resin such as an FRP or a vinyl chloride resin, filling resin concrete onto an outer surface of the case, and combining the case and the concrete with each other in one body. In this manner the high-strength drainage tank which avoids the effect of the earth pressure load is produced. COPYRIGHT: (C)2006,JPO&NCIPI
