ABSTRACT OF THE DISCLOSURE For the ditching of drains normally various types of excava- ting machines are used. This involves problems, however, especially when the ground has poor carrying capacity, for example in wetlands. According to the invention, therefore, a body is proposed which has substantially V-shaped cross- section and smooth lower sides, and which is advanced through the soil masses to be removed for ditching the drain with a pointed end along the height of the body closed end facing in the direction of advancement, and which simultaneously is subjected to at least downwardly directed striking forces with relatively high frequency, whereby the body is maintained pressed down into the soil masses while it is being advanced. The soil masses are thereby removed substantially in lateral directions by the side surfaces of the body and compacted. For effecting the striking forces, preferably a vibrator is provided within the body.
