摘要： When driving a tube (24) into the ground, primarily for subsequently loading the tube with an explosive substance and subsequent blasting of the surrounding ground, a driving rod (20) whose rear end is provided with an insert end (13) which can be connected to a percussion machine (36) is employed in the driving operation. The non-metallic tube (24) is fitted over the driving rod (20), against an axial stop (16). A forwardly located, conical sacrificial tip (28) has a base cross-section dimension (30) which corresponds to the outer dimension of the tube (24), followed by a neck portion providing a shoulder (31). The tip (28) is supported by the shoulder (31) with clamping engagement with the tube in an orifice of the tube, and forms, together with the tube (24), a unit (24, 28) which is fitted onto the driving rod (20) and brought into impact contact between an anvil surface (33) on the tip (28) and the forward end (21) of the device. The device (12), together with the tube (24), and the tip (28) mounted on the tube, penetrates the ground to a desired depth with the aid of a machine (36), and the device (12) is withdrawn leaving the tube (24) in the ground ready to be loaded with an explosive substance and blasted, or for some other use. The tube (24) can be used as a cartridge case for an explosive charge insert (24; 37), which can be removed from the tube prior to driving the tube into the ground.
