ABSTRACT:
A method and a hollow body for forming a hole in the ground are disclosed. After the hollow body has been brought to the desired depth in the ground high pressure fluid is jetted through spray nozzles into the hollow body near the lower end thereof. The fluid jets effect a cutting of the ground core in the hollow body whereafter the pressurized fluid displaces the overhead ground core upwardly. The spray nozzles are spaced circumferentially and lie in the same transverse plane so that a very flat horizontal cut in the ground is accomplished by the fluid jets.
