The invention discloses a riveting-based tank body structure which comprises a tank body and lifting lugs; the tank body comprises first vertical plates, second vertical plates, a bottom plate and a top plate; each first vertical plate comprises a first vertical plate body and first bent parts; the first bent parts perpendicular to each first vertical plate body are arranged on the same side of the four edges of each first vertical plate body; each second vertical plate comprises a second vertical plate body and second bent parts; the second bent parts perpendicular to each second vertical plate body are arranged on the same side of the upper end and the lower end of each second vertical plate body respectively; the bottom plate and the top plate are horizontally arranged in parallel; thefirst vertical plates and the second vertical plates are vertically arranged, are mutually perpendicular and all perpendicular to the bottom plate and the top plate; the first bent parts are abutted to the second vertical plate bodies, the second bent parts, the bottom plate and the top plate respectively and are in riveting connection with the second vertical plate bodies, the second bent parts,the bottom plate and the top plate to form the tank body; and the lifting lugs are arranged on the upper side of the front side or the back side of the tank body and are detachably and fixedly connected with the tank body. The tank body structure is formed by riveting the plates and ensures the sealing grade of the tank body while considering the strength.
