Abstract

The invention discloses a double-liquid grouting three-dimensional cyclone mixer apparatus. The double-liquid grouting three-dimensional cyclone mixer apparatus comprises a slurry-A inlet pipeline, aslurry-B inlet pipeline and a mixed slurry outlet, wherein the slurry-A inlet pipeline is connected with an outer layer pipe, the outer layer pipe is connected with a high-pressure stop valve by virtue of a direct connector, the slurry-B inlet pipeline is connected with an inner layer pipe, the slurry-B inlet pipeline is also connected with a slurry-B distribution slurry outlet and is connected with a mixed slurry distribution rod by virtue of a pipe hoop, and the mixed slurry outlet is connected with the inner layer pipe and the outer layer pipe. By adopting the double-liquid grouting three-dimensional cyclone mixer apparatus, two types of slurry can be sufficiently mixed in all directions, so that the dispersity of the slurry is improved, the mixing rate of the mixed slurry is increased,the solidification time of the mixed slurry is shortened, the loss of the slurry is reduced, construction materials are saved, the cost is reduced, double liquid injection can be effectively carriedout under a flowing water condition, and a good effect of reinforcing a shallow layer of double liquid of a complicated soft stratum can be achieved.

Description

technical field [0001] The invention relates to the technical field of grouting, in particular to a three-dimensional swirl mixer device for double-liquid grouting. Background technique [0002] At present, in the grouting project, after the borehole construction is completed, the borehole reveals a large water gushing situation in the multi-layer aquifer layer. In the existing grouting technology, the casing is directly grouted after being lowered into the casing. When the cement slurry enters the crack, a part of the slurry in the weak and broken formation is easily formed with continuous injection. Part of the slurry is easy to be diluted by water, and the resistance to separation is insufficient. During the grouting process, the grout does not have enough time for initial setting, and a single grout cannot meet the requirements of grouting and water blocking. It is difficult to effectively block the gushing water. In the past, it was common to inject double-fluid grou...
