grouting pressure

When the slurry filling, pressure gradually increases, easy to control and maintain the grouting pressure.

The grouting pressure difference varied with consistency coefficient linearly and with rheology parameters of grouting nonlinearly.

The chemical grouting is one of effective methods to treat mine quicksand in difficult grouting strata with low grouting pressure.

Although grouting pressure changes at any time, it has a dynamic variable range.

By using the formulas the variation of necessary grouting pressure required the design along the depth of stratum can be calculated. 2.

However, at the same velocity, the grouting pressure will increase with the decrease of the groutability of rock mass.

Through energy balance equation, the different grouting pressure on the whole process of grouting was discussed.

High grouting pressure can decrease the magnitude of soil stresses release, and accelerate the drainage ratio of water.

The pipelines maximum stress turns greater when grouting pressure turns larger.

Combined with the obtaindresults of some case histories, the variations of grouting pressure and grouting flow were demonstrated.

And the final grouting pressure of the piles in the late grouting order is larger.

The grouting pressure formed by cement type suspensoid is greater than that by high molecular chemical slurry.
