Oxidation digestion method for treating forming of mud cakes of shield cutter head

The invention provides an oxidation digestion method for treating forming of mud cakes of a shield cutter head. When the mud cakes are formed, a shield machine shuts down, a decomposition solution isinjected into a shield excavation cabin and the shield cutter head, the formed mud cakes are soaked and decomposed, when the decomposition is completed, the construction of the shield machine is resumed, wherein the decomposition solution is an oxidant solution; and an exhaust outlet is formed in the upper part of the shield excavation cabin, and gas generated from the oxidant solution in the process of decomposing the mud cakes is discharged. The oxidation digestion method is a chemical treatment method for forming of the mud cakes of a shield without opening the cabin, the method can automatically remove the mud cakes without opening the cabin, manual treatment is not required, investment and construction time are saved, meanwhile, the safety risk of personnel can be avoided, and the oxidant solution mainly gene
