Claims

[Scope of Claim for Utility Model Registration] A drilling tower is erected on a skid, a drilling rod is held on the drilling tower so that it can freely rotate and move up and down, and as the drilling rod is rotated and pushed downward, high-pressure drilling fluid is passed through the inside of the drilling rod. In an excavator that excavates while injecting high-pressure drilling fluid from the lower end, a power swivel is attached to the excavation tower so as to be able to move up and down, and the rotating shaft of the power swivel has a double pipe structure. A drilling rod having a double pipe structure is connected to the inner pipe and the outer pipe of the power swivel, respectively, so that high pressure drilling fluid can be supplied to the inner pipe of the power swivel, and low pressure fluid can be supplied to the outer pipe of the power swivel.
