The utility model relates to the technical field of subsea tunnel pipeline protection equipment, and discloses a subsea tunnel pipeline joint anti-corrosion assembly which comprises a shell, an auxiliary mechanism is fixedly connected to the bottom of the shell, and protection mechanisms are arranged on the left side and the right side of the shell. According to the subsea tunnel pipeline joint anti-corrosion assembly, the protection mechanism is arranged, in the using process, the two ends of a pipeline are placed in through conical holes in the middles of arc-shaped blocks on the two sides, then a threaded rod is rotated through a handle till the arc-shaped blocks cannot continue to move, and at the moment, the pipeline joint is sealed under the action of a sealing strip and a sealing block; the protection mechanism seals the pipeline joint, wet air in the subsea tunnel is prevented from making contact with the pipeline joint, the phenomenon that the joint is corroded due to the influence of the wet air is
