Abstract (en)
Reusable formwork for construction in concrete, especially for defining the "growing" end of a concrete diaphragm wall or other wall being formed below ground level, comprises at least two rigid formwork bodies (1, 3, 4, 7) together forming a containing surface for concrete to be cast. Mechanical means (such as hydraulic jacks J1, J2, J3) are provided for producing forces across the containing surface (2) tending to produce relative movement of the rigid bodies and sufficient to release one of them from adhesion to concrete cast on the said containing surface. Preferably there are more than two of the rigid bodies arranged so that by actuating them in appropriate sequence they can all be released. <IMAGE>
