Process for applying consolidation masses, preferably for tunnels and mine roadways, with reinforcing fibres

摘要

In order to prevent destruction of the fibres in forced-mixing devices during the application of consolidation masses with fibre reinforcement, it is proposed according to the invention that, in the region of the delivery nozzle (2), a handy stock vessel is fitted which has a controllable fibre-cutting device (5) at the outlet, and fibres of a length according to requirements are cut and then admixed hydraulically or pneumatically under the delivery pressure via a delivery pipe (6) associated with the cutting step to the emerging nozzle jet. The jet delivered from the material nozzle (2) has a velocity of more than 15 m/second. The delivery nozzle (2) is provided with an attached vessel, which is subdivided into a cutting device (5) and a delivery pipe (6) which, at the discharge end, slightly diverges in the direction of the delivery jet. <IMAGE>
