The floating ball 3 is arranged in the slurry testing half barrel 2, the density of the floating ball 3 is slightly lower than the preset specific gravity of the slurry, and preferably, the density of the floating ball 3 is about 0.1 lower than the preset specific gravity of the slurry. Referring to fig. 4, when the specific gravity of the actual mud is greater than or equal to the preset specific gravity, the floating ball 3 floats on the liquid level a of the mud testing half cylinder 2, which indicates that the specific gravity of the mud at the moment meets the design requirement and can be used for normal construction, and the current adding amount of cement and water can be continuously used. Referring to fig. 5, when the specific gravity of the actual slurry is smaller than the preset specific gravity, the gravity of the floating ball 3 is larger than the buoyancy, the floating ball 3 sinks to the bottom of the slurry testing half barrel 2, which indicates that the specific gravity of the slurry at the moment does not meet the design requirement and cannot be used for construction, at the moment, the normal construction of the cement mixing pile is stopped, the adding amount of the cement is increased, and the construction is carried out until the floating ball 3 floats on the liquid level a of the slurry. In specific implementation, the pulp outlet cylinder 1 is a circular cylinder with the radius of 800mm and the height of 100mm, and the pulp testing half cylinder 2 is a square half cylinder.
