Special bubble-free anti-caking mud cake engineering material for slurry shield and injection method of special bubble-free anti-caking mud cake engineering material

The invention discloses a special bubble-free anti-caking mud cake engineering material for a slurry shield and an injection method, and belongs to the technical field of slurry balance shield construction. Comprising the following components in percentage by mass: 8-10 wt% of a dispersing agent, 0.5-1 wt% of a stabilizer, 0.5-1 wt% of a defoaming agent, 0.5-1 wt% of a corrosion inhibitor and the balance of water. In the slurry circulation process of the slurry shield, slurry containing the special bubble-free anti-caking mud cake engineering material for the slurry shield can be prepared and participates in slurry circulation in the whole process, and mud cakes are prevented from being generated; in the slurry circulation process, after the slurry viscosity is increased, the special bubble-free anti-caking mud cake engineering material for the slurry shield can be directly injected into a slurry cabin. The engineering material and the method can effectively solve the problem of mud cake formation of a slurry
