Drain ladle
To lay drainage pipes, a trench is first dug one or two stitches deep (and
approx. 50-60 cm wide) with the garden spade and the spade. After the loose
soil that the spade has not been able to absorb has been removed with a
masonry shovel, also with a kind of flat drain laddle, the trench is
brought to depth with the narrow drain spade. Finally, with the drain
laddle, the bottom of the trench is finished very accurately and at the
required slope, so that the pipes can be placed on it (see pipe layer); the
worker is standing next to the slot. [MOT]
