device for smesovu00e1nu00ed at conjugate injektu00e1znu00ed smesi in injektu00e1znu00edm pipe (2) in an envelope (1) stu00edtu tunnelling machines for injektu00e1z area between the ostenu00edm and vu00fdrubem tunnelwhere one of the components is a liquid cementovo - bentonitovu00e1 suspension and the second component of accelerator its solidification.in injektu00e1znu00edm pipe (2) is usporu00e1du00e1na pruznu00e1 hose (4) for pru00edvod liquid urychlovace solidification in cementovo - bentonitovu00e9 suspension jeju00edz end is closed and is opatren membranetvorenou at least one narrow sterbinou (6) in the hose (4), situovanou in area of the injektu00e1znu00edho pipe (2).the hose (4) is of a material inert to chemical and mechanical components smesi using, for example silicon pryze, and is closed to vlepenou pruznou stopper (5) from the silicon compact pryze.sterbiny (6) in the hose (4) may be elongated and are rozmu00edsteny on the circumference of the hose (4). may be tvoreny prorezem pruznu00e9 hoses (4) without loss of material.the inner wall of the injektu00e1znu00edho pipe (2) may be opatreny layer of a material inert to chemical and mechanical components smesi using, for example silicon pryze.
