FIELD: construction.
SUBSTANCE: invention relates to foundation construction, is intended for embedment in weak water saturated ground of natural or artificial addition of fine-grained concrete or sand-concrete to required depth for its fixation and hardening. Embedded injector comprises hollow housing with fixator for concrete pipe in upper part; with outlet holes, made in its lower part and fixed tip. Cylindrical metal hollow barrel with embedded tip is placed inside hollow housing in its lower part, attached to injector housing by means of transverse steel axis with four output holes of rectangular shape. Opening of holes is performed due to lowering of cylindrical metal hollow barrel with embedded tip under pressure supplied to solution injector barrel. Wherein total area of outlets should exceed transverse size of injector by 1.1 times.
EFFECT: technical result is increase of efficiency of embedded injector.
