<p>The method involves providing lower and upper hold parts (41, 42) with a movable upper surface for supporting abutment elements (31-33). The lower hold part is located on an upper floor around a bar (2). Actuators (5) are positioned on the upper floor beside the bars. The upper hold part is positioned on a support (52) of a moving part and around the bars. One of the abutment elements is positioned above the upper hold part. A suspended formwork (1) is lowered by lowering the bars in successive stages while acting on positions of the abutment elements and the moving part. An independent claim is also included for a kit for building an underground structure with a suspended formwork.</p> |
