An apparatus for pouring a fluid hardening mass, such as concrete, in layers under water is disclosed. The apparatus comprises a hopper with a downwardly directed pouring tube (1) and a widened pouring tube foot (4). The widened pouring tube foot (4) comprises, from the edge of the flowout opening (2) of the pouring tube (1), a substantially radially outwardly extending bottom plate (3). The bottom plate comprises an upright collar (10) on its outer circumference. The bottom plate (3) of the pouring tube foot (4) has a stepped configuration, the lowermost part of which forms a supporting portion (9) adapted to rest on the bottom (12) and the higher part of which constitutes the lift portion (5, 6, 7) of the pouring tube foot (4). <IMAGE> |
