Abstract (en)
The invention relates to a method for producing a concrete tube (6) in a mould (1) and removing the tube (6) from said mould (1), which method comprises the steps of: - providing a mould (1) comprising an elongate core (3) and a partitioned shell (4) arranged around the core (3); - filling the mould (1) with a liquid concrete (C); - allowing the concrete (C) to set and cure in the mould; - after the concrete has set and cured, applying a force between the core (3) and the shell (4) in longitudinal direction of the elongate core, such that the elongate core is pulled out of the set concrete; - opening the partitioned shell (4) by taking apart at least two shell parts (8, 9); - removing the set and cured concrete tube (6).
