HEAD FOR FORCING OF CONSOLIDATING LIQUID MIXES AT PRESSURE Russian patent published in 2015 - IPC E02D3/12 E21B43/114 

FIELD: process engineering.

SUBSTANCE: invention relates to high-efficiency head for forcing liquid mixes into soil to form compacted soil areas. Proposed head (10) comprises the components that follow. Outer cylindrical case (12) to define the central lengthwise axis (Z) and at least one top inlet (16) to intake fluids from tubing arranged above said head. At least one outlet side nozzle (11) is arranged in the plane, in fact, perpendicular to said axis (Z). At least one spiral channel (13) makes the spiral central line (m). Channel (13) communicates top inlet (16) with nozzle (11) to swirl the fluid therein about lengthwise axis (Z) to nozzle (11). Spiral channel (13) gradually converges to nozzle (11) and comprises the channel end section bent to said nozzle with convergence. Note here that spiral channel and end section in the lanes of cross-section are parallel with lengthwise axis and run tangentially to the spiral central axis and in cross-section planes and are perpendicular to lengthwise axis.

EFFECT: higher fluid flow velocity and lower turbulence at normal power consumption.
