Abstract (en)

[origin: CA3170952A1] The invention relates to a ground working device for creating a substantially vertically extending hole in the ground, which hole is provided with a supporting fluid, said ground working device having a main body, a connection device which is arranged at an upper end region of the main body, and a ground removal device and/or a ground displacement device which is arranged at a lower end region of the main body. According to the invention, at a lower region of the main body, a first pressure measuring device for measuring a first ambient pressure is arranged, and at an upper region of the main body, which is vertically spaced apart from the lower region, a second pressure measuring device for measuring a second ambient pressure is arranged. The invention also comprises a method for creating a substantially vertical hole in the ground using such a ground working device.
