Soil working device and method for creating a substantially vertical hole in the ground

A method for creating a substantially vertical hole in the ground by means of a soil working device having a basic body, a connection apparatus which is arranged at an upper end region of the basic body, and a soil removal apparatus and/or a soil displacement apparatus arranged at a lower end region of the basic body, wherein at a lower region of the basic body a first pressure measuring apparatus for measuring a first ambient pressure is arranged, and at an upper region of the basic body, which is vertically spaced apart from the lower region, a second pressure measuring apparatus for measuring a second ambient pressure is arranged;

• wherein the hole is filled with a slurry during creation, and by means of the first pressure measuring apparatus, a first ambient pressure in a lower region of the soil working device is measured and by means of the second pressure measuring apparatus, a second ambient pressure in an upper region of the soil working device is measured,
• the first pressure measuring apparatus is fluidically connected to the second pressure measuring apparatus by means of a connection line, and
• a sensor apparatus is arranged on the connection line, with which sensor apparatus a pressure difference between a first pressure at the first pressure measuring apparatus and a second pressure at the second pressure measuring apparatus is sensed.
