METHOD FOR PRODUCING MATERIAL COLUMNS AND VIBRATING DEVICE HAVING A RECIPROCATING UNIT

摘要

The invention relates to a device for producing material columns in the ground, to a vibrating arrangement, and to a method for producing material columns. The device comprises: a vibrating arrangement (1) having a vibrator (12), at least one first material pipe (11; 111), which has a longitudinal direction, and a material outlet (13) at a lower end of the first material pipe (11; 111); a carrying device (2) for the vibrating arrangement (1), which is designed to move the vibrating arrangement (1) in the longitudinal direction of the first material pipe; at least one lifting unit (3), which is arranged between the carrying device (2) and the first material pipe (11; 111) and which is designed to move at least the first material pipe (11; 111) in the longitudinal direction of the first material pipe.
