ABSTRACT:
The formwork assembly (10) is used to cast tubular or part-tubular structures, one particular application being in the lining of mine ore passes with a concrete lining (54). The assembly includes an internal framework (12, 14, 32; 100, 102, 104) and external, flexible formwork (34, 130) supported by the framework. The framework can be adjusted between a casting condition (FIG. 1) in which it supports the formwork (34, 130) at the inner periphery of the structure which is to be cast and an inwardly collapsed condition in which it supports the formwork (34, 130) at a position spaced inwardly from such inner periphery. In the case of a mine ore pass lining, the assembly is moved upwardly in increments after each casting operation.
