Definitions
- the invention relates to a Rüttleran extract and a method for producing material columns, which are introduced to improve the soil properties of soil in the soil.
- the material transport to the lower end of the vibrator is done solely by the gravity acting on the material. Without rinsing water or without a conveyor pipe, the transport of gravel in soil layers below the groundwater level is not possible. To speed up the transport or when the material transport has come to a standstill, only the enlargement of the annulus remains, which is undesirable in most cases, however, because this has an unnecessary leaching of soil and an increased need for rinse water result.
- Object of the present invention is to provide an apparatus and a method for the production of Stopf yarn available in which compared to the prior art no, or only a smaller need for rinse water and also no delivery pipe is necessary.
- a vibrator arrangement comprises an elongated vibrating body with a circumferential surface. Arranged on this circumference is a projection which extends away from the vibrator body in a lateral direction and which extends around the circumference at least in sections.
- the projection is preferably configured to penetrate at an acute angle into a lower end of the
- the geometry of this projection can correspond to the geometry of a truncated cone or a truncated pyramid.
- the projection may have a plurality of circumferentially arranged segments.
- a plurality of projections can also be arranged along the longitudinal direction of the vibrating body.
- the projections are movable along the longitudinal direction of the Klattel stressess.
- the projection or individual segments of the projection in the direction of the lateral surface of the Schwarztelelless can be folded or inserted into the Schwarztelharmonic retractable.
- the vibrating arrangement can be designed, in particular, as a depth vibrator with an eccentric arranged in the vibrating body or else as a top vibrator with an eccentric arranged on an upper end of the vibrating body.
- the material flow per unit of time is increased by more than 50 percent and the required amount of flushing water is at least halved.
- water it is also possible to use air or another gas blown into the annular space for "flushing". In some soils, the water or gaseous rinsing medium can even be completely dispensed with.
- FIG. 1 shows an example of a device according to the invention
- Jogger arrangement with a vibrating body and a projection.
- FIG. 2 shows a further example of a vibrating arrangement according to the invention with a vibrating body, in which the projection is arranged at the lower end of the vibrating body.
- FIGS. 3A-C show different embodiments of the projections.
- like reference numerals designate like parts with the same meaning.
- FIG. 1 shows a side view of an embodiment of the vibrator arrangement 1 according to the invention.
- This comprises an elongate vibrating body 2, which has a circumferential surface 22 with a circumference and a lower end 21 and an upper end (not further shown).
- a projection 3 is arranged, which projects in the lateral or rather radial direction from the vibrating body 2. This projection 3 widens in the direction of the lower end 21, i. the projection is increasingly in the direction of the lower end 21 of the lateral surface 22 of the vibrating body 2 from.
- the projection can extend annularly around the circumference of the vibrating body 2.
- the vibrating body 2 may in particular be cylindrical in shape and thus have a circular cross-section.
- the vibrating body can also have any other cross section, in particular a rectangular cross section.
- the projection 3 has, for example, the geometry of a truncated cone or pyramid stump penetrated by the vibrator body.
- an underside 32 of the projection facing towards the lower end of the vibrating body projects approximately at right angles from the vibrating body 2, while an upper side 31 of the projection tapers with increasing distance from the lower end 21 of the vibrating body, so that the projection 3 in the example has the shape of a truncated cone penetrated by the Rüttelmaschinen.
- the projection 3 can at any longitudinal position of the
- the exemplary embodiment according to FIG. 2 differs from that shown in FIG. 1 in that the projection 3 is arranged at the lower end 21 of the vibrator body.
- the vibrating arrangement can be realized, for example, as a deep vibrator or as a topping vibrator.
- a vibration-generating eccentric (not shown) is arranged in the vibrating body 2.
- the eccentric (not shown) above the upper end of the vibrating body 2 is arranged.
- the upper side 31 of the projection 3 conically extends at an acute angle to the longitudinal direction of the elongated vibrating body 2, while the lower side 32 is at an approximately right angle with respect to the longitudinal direction.
- the projection 3 is designed as a body.
- FIG. 3B shows an embodiment of a segmented projection 3 with a plurality of segments 40, 41, 42, 43 arranged circumferentially adjacent to one another. This embodiment makes it possible to fold the projection 3 into the vibrating body 2 or to retract the projection 3 into the vibrating body 2.
- the embodiment of the projection 3 shown in FIG. 3C differs from the embodiment in FIG. 3A in that the underside 32 of the projection likewise has a tapered, tapering profile, as a result of which mentioned blade effect of the projection 3 can be improved.
- a column-shaped hole is first produced.
- Such a hole typically has a diameter of about 50 cm to 100 cm.
- the vibrating body 2 used according to the invention typically has external dimensions of about 30 cm to 50 cm.
- the material located in the annular space 4 is detected by the projection 3 and transported in the direction of the lower end of the vibrating body 2 in a downward movement of the vibrating body.
- possible wedges of material in the annular space 4 between the vibrating body 2 and the bottom 5 are broken.
- the upward movement of the oblique course of the top 31 of the projection ensures that the material is displaced laterally and not transported back up.
