Abstract (en)
[origin: EP0044272A2] The device consists of a nozzle connection (20) and an element (26) which is inserted between the start (11a) of a rock anchor designed as a pipe (11) and a sealing surface (24) of the nozzle connection (20). The nozzle connection (20) comprises two concentrically arranged pipes (22, 23) for the separate feed of the two components (B,K) of a two-component adhesive. The element (26) consists of a plastically deformable material and has a cylindrical collar surrounding the start (11a) of the pipe and a flange (27). The outer wall (22) of the nozzle connection (20) ends in an edge (25) as an intersection line between a conical surface and a cylindrical surface. A static mixer (13) is inserted at the start (11a) of the pipe. A two-component adhesive can be pressed at a pressure of 120 bar into the pipe (11) by this device in order to fill the pipe and the intermediate space between the outer surface of the pipe and the wall of a drill hole for the purpose of producing a non-prestressed anchor for consolidating rock. The non- prestressed anchor can consequently be set by machine. <IMAGE>
