Device for producing a material column in the ground and method for filling the device

Abstract

The invention relates to a device for producing a material column, in particular a vibrating tamping column, from a bulk material in the ground, having an infeed pipe, which is designed to be driven into the ground and has at least one material outlet opening at a lower end, a vibrating drive, which is designed to cause the infeed pipe to vibrate and is arranged, in particular, on a lower region of the infeed pipe, a receiving bunker, which is designed to receive a quantity of bulk material and is arranged on an upper region of the infeed pipe, and a compressed air supply device for introducing compressed air into the inside of the infeed pipe. According to the invention, it is provided that a sensor device is arranged, which is designed to detect a filling level of bulk material down to a lower region of the infeed pipe, that the receiving bunker is designed with a closed housing with a closable supply opening for supplying bulk material into the receiving bunker, wherein the supply opening can be closed in an airtight manner by means of a closing device, and that a passage between the receiving bunker and the infeed pipe being arranged below, is open when the bulk material is inserted into the ground, wherein the filling level of bulk material in the infeed pipe can be detected by the sensor device. The invention also relates to a method for filling a device for producing a material column.
