The utility model belongs to the technical field of shield maintenance, and particularly relates to a treatment structure of a shield mud lining. The problem that an existing shield mud lining treatment method is high in investment and risk is solved. The treatment structure comprises a mud wall arranged at the position 20 m to 40 m in front of the construction position under the condition that the shield mud lining phenomenon is not quite serious, the bottom of the mud wall is located at the position 2 m below the lower edge of a shield cutter disc, the top of the mud wall is located at the position 2 m above the upper edge of the shield cutter disc, the mud wall is formed by broken brick layers and cemented soil layers in an alternate mode from top to bottom, and the height of each broken brick layer and each cemented soil layer is 1 m. The treatment structure has the advantages that a brand-new bin-opening-free unartificial method can be achieved, the construction of removing a mud cake in the claypan construction process of the shield is achieved successfully, an existing treatment method for eliminating the shield cutter disc mud cake is completely subverted, according to the treatment structure, a bin does not need to be opened, personnel do not need to enter the bin, the cost and the construction period are greatly saved, and meanwhile the treatment structure is safe, reliable and high in efficiency.
