Abstract (en)
A stop-end pipe (1) for the construction of concrete diaphragm walls, which comprises a longitudinally extended structure (3) which has at least one first face (5) configured to face the concrete (7) intended to fill an excavation (9) for the provision of a diaphragm wall, at least one tubular chamber (11) being associated with the first face (5) and having a longitudinal axis which is substantially parallel to the axis of longitudinal extension of the structure (3), where the tubular chamber (11) is expandable hydraulically in a direction that is transverse to its axis, so that the expansion of such tubular chamber (11) is adapted to impart a translation of the stop-end pipe (1) with respect to the concrete (7), such translation being intended to detach it from the concrete that is present in the excavation (9).
