- the lifting units 3A, 3B are arranged in the device according to FIG. 7 in the vibrator arrangement 1, which in this case has two material tubes: a first material tube 11 ⁇ in the lower region of the vibrator arrangement 1, and a second material tube 11 2 in the upper region of the vibrator arrangement.
- the vibrator arrangement shown in FIG. 7 is realized as a deep vibrator.
- the vibrator 12 is in this case arranged below the first material tube III.
- the statements in connection with FIG. 1 with regard to the arrangement of the vibrator on the material tube 11 shown there apply correspondingly.
- the vibrator arrangement could also be realized as a topping vibrator.
- the vibrator is arranged on the upper material tube 11 2 .
- the feed arrangement with the material container 14 and the material opening is arranged on the upper material pipe 11 2 .
- the filling arrangement 14, 15 shown in FIG. 7 any further filling arrangements could also be provided.
- a closure 17 shown in phantom
- Any necessary overpressure must be te then not in the entire tube assembly with the first and second material tube, but only in the region of the first material tube below the closure 17 are generated.
- the first material tube 11 x and the second material tube 11 2 are realized so that they are mutually displaceable in the longitudinal direction of the vibrator 1.
- the lifting units 3A, 3B are arranged between the first and second material pipes Iii, 11 2 and are designed to displace the first material pipe Iii in the longitudinal direction of the vibrator arrangement relative to the second material pipe 11 2 .
- the second material pipe 11 2 is fixedly attached to the support member 21 of the support device 2.
- the feed arrangement 14, 15 also remains stationary if strokes of the first material tube III are carried out using the lifting units 3A, 3B for the purpose of compressing introduced material.
- the lifting units 3A, 3B for the purpose of compressing introduced material.
- the lifting units 3A, 3B are arranged in the illustrated example in each case outside the material pipes Iii, H 2 , wherein the material pipes Iii, ⁇ 2 are realized in the example so that they are tapered in the region of the lifting units 3A, 3B. As a result, the lifting units 3A, 3B do not project beyond the vibrator arrangement 1 in the lateral direction. This is only optional.
- the dimensions of the vibrator arrangement 1 are predetermined in the lateral direction essentially by the diameter of the first material tube III in the lower region of the vibrator arrangement 1 and the diameter of the second material tube 112 in the upper region of the vibrator arrangement 1.
- the lifting units 3A, 3B can be protected to the side by a cover 18 2 , which is attached to the second material tube 11 2 and protects the lifting units 3A, 3B against pollution in the ground.
- first and second material tubes Iii, 11 2 in their longitudinal directions can also be coordinated so that during operation of the vibrator 1 not the upper second material tube 11 2 but only the lower first material tube Iii penetrates into the ground.
