Description
Technical Field
The utility model relates to a slurry mobility testing arrangement belongs to hydrodynamics technical field.
Background
The construction often needs slurry materials which are injected into the stratum, and when the content of the extremely fine particles and water in the slurry is higher, the pressure loss of the slurry in a grouting pipe during the injection is smaller, and the pressure at the outlet of the grouting pipe is higher, so that the slurry is injected into the stratum more. However, the higher the content of the ultrafine particles and water in the slurry, the greater the amount of final shrinkage deformation of the slurry in the formation, and the poorer the grouting effect. Therefore, it is necessary to quantitatively measure the pressure loss of the slurry in the grouting pipe, thereby scientifically and reasonably determining the proportioning of the slurry.
However, in the experiment, there is no apparatus for quantitatively measuring the fluidity of the slurry in the grouting pipe, and in order to evaluate the fluidity of the slurry in the engineering, a consistometer is generally used, and when the standard cone is not sunk into the slurry any more in the measurement, the sinking depth of the cone is used as a test index for evaluation. However, the sinking depth of the cone is greatly influenced by manual operation when the device is adopted, the results of two tests before and after the slurry with the same proportion are greatly different, and more importantly, the sinking depth of the cone is not internally connected with the pressure loss of the slurry in the grouting pipe, and the corresponding relation is not strong.
