SYSTEM FOR COATING THE INNER WALL OF TUBES

摘要

System for coating the inner wall of a pipe (20), a tunnel etc., comprising a) a spray unit (30) for spraying the coating material onto the inner wall of the pipe, b) transport means for moving the spray unit through the pipe, c) means for supplying the coating material to the spray unit, whereby the means mentioned under b) are embodied as a relatively stiff tube (14) which is initially wound on a drum (38) or reel and is guided by guide means to an injector unit which forces the pipe in the one or in the other direction, and whereby the end of the tube has coupling means to connect the tube to the spray unit.
