摘要： For the ditching of drains normally various types of excavating 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 (1) 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 and 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 (1) is maintained pressed down into the soil masses while it is being advanced. The soil masses are thereby removed substantially in lateral direction by the side surfaces (2) of the body and compacted. For effecting the striking forces, preferably a vibrator (11) is provided within the body (1).
