A method of measuring the dynamic pressure of the bore grout

A method of dynamic measurement hole grouting pressure, comprising the step of first collecting the related art grouting process parameters, and then determining the model structure filling pressure measurement, to establish the grouting fluid conduit slurry micelle Based Lattice Boltzmann Method pressure distribution model function, and then summing the distribution function based on a deep position in the slurry pressure grouting pipe particular well, to give a slurry and the slurry macro macro pressure filling speed specific site; grouting slurry to the lowermost end of the pipe Representative macroscopic pressure grouting process the pressure in the filling, the final amount of change when the flow rate during the grouting slurry density of 10% or changes, the data is updated in real time to guide the grout job. Dynamic pressure measurement hole grouting of the present invention as long as it knows the speed and the aperture value of the density of the slurry can be acquired at any pressure in the pipeline, the operation is simple, and more accurate and reliable data.
