Abstract (en)
The invention relates to a method for making a trench (9) under water, wherein bed material (10) of the trench (9) for excavating is processed by means of water under pressure flowing out of at least one water jet (7), wherein the water jet (7) is displaced in an at least partially dug-in position along the path of the trench (9), that water under pressure is sprayed from the water jet (7) in a spraying direction (18) lying transversely of the trench direction along the bed material (10) of the trench for excavating and that by means of at least one auxiliary water jet (8) water under pressure is sprayed at bed material (10) of the trench (9) for excavating such that the displacement path of the water jet (7) is cleared. The invention also relates to a device for performing the above stated method. <IMAGE>
