The volume of the pulp storage barrel is generally less than 0.3-0.8m ³ The grouting by the grouting pump needs a certain time, and often precipitation segregation phenomenon can occur in the grouting process, especially when single-liquid cement slurry or ultra-high water material double-liquid cement slurry which is easy to precipitate is poured, the precipitation segregation phenomenon is easier to occur.

Therefore, the proportion of the slurry actually poured into the cracks is often greatly different from the designed proportion, so that parameters such as the bonding time of the slurry, the strength of a stone body and the like are influenced, the grouting effect is inferior to the problem of design expectation, and the construction safety cannot be ensured.

If the electric stirring device is configured for the slurry storage barrel to ensure the uniformity of slurry, the following defects exist:

because the slurry storage barrel is of an upper opening structure, the stirring device has the hidden trouble of hurting people by electric shock or hurting people by the fault of the stirring blade when working;

the stirring device is of a dynamic structure, so that the unstable condition of the pulp storage barrel can occur;

because the stirring device is in single rotary motion, the vertical consistency of the slurry cannot be truly ensured.
