Abstract
A shotcrete nozzle assembly comprising: a tubular body including a body sidewall defining a central passageway extending along a central longitudinal passageway axis, and water dispensing bores extending through the body sidewall and including: first and second sets of water dispensing bores positioned such that outlet openings thereof defined in an inner face of the body sidewall are disposed in a respective one of longitudinally spaced-apart first and second transversal planes extending perpendicularly to the passageway axis, at least some of the water dispensing bores being oriented such that the central bore axes thereof extend in a non-radial direction relative to the passageway axis, and such that an orthogonal projection of the central bore axes of the first and second sets of water dispensing bores onto one of the transversal planes forms first and second projected central bore axes which intersect each other at a first non-zero angle.
