With a method and device for producing a channel in the ground, in a first
step, an excavating device is positioned at the starting point of a
channel to be produced. The excavating device has an excavating head
which is provided with one or more liquid jetting devices. Then, a
mixture of soil and water is formed by spraying liquid from the liquid
jetting devices. This mixture is discharged. The excavating head advances
in the excavating direction while the liquid is being sprayed. Thus, the
channel is produced. When the end point of the excavation has been
reached, at least a part of the excavating device is uncoupled and moved
back to the starting point of the channel, so it can be used again.
