<p>The present invention relates to equipment for making holes by penetration in a surface (1), which equipment (2) comprises a pressure source (9) for supplying a pressurised fluid (5), a nozzle assembly (11), a conduit (12) between the pressure source and the nozzle assembly (11) for supplying the pressurised fluid (5) from the pressure source (9) to the nozzle assembly (11), wherein the pressurised fluid substantially in the form of a jet (6) is made to flow out of the nozzle assembly (11) and towards the surface (1) to penetrate through the same for making a hole and, when the surface has been penetrated, being injected into a space, wherein a vessel (13) containing an additive (8) is connected to an inlet (34, 34') at the nozzle assembly (11) and that the pressurised fluid (5) when being transferred through the nozzle assembly (11) creates a pressure difference that entrains additive from said vessel (8) into the nozzle assembly (11) so that the fluid being made to flow out of the nozzle assembly (11) comprises a mixture of pressurised fluid (5) and additive (8). The present invention also relates to a method for making at least one hole in a surface (1) and supplying fluid to a space, wherein said at least one hole is produced by penetration.</p> |
