Definitions
- the invention relates to a device for soil compaction according to the preamble of claim 1.
- the compaction force by planar Body e.g. Apply vibration plates, where the voltage curve is much cheaper in the soil to be compacted, since no here pronounced voltage peaks occur and also the vertical applied forces dissolve much more slowly in the depth.
- the vibrating Roller of the soil compaction device in the circumferential direction a plurality of individual segments, so that in Circumferentially alternating successive, continuously into one another Bandagenausput convex arc sections of two different Curvatures are formed, with the one curvature stronger and the other curvature is weaker than that of the one Outer outline of the roller circumscribing cylinder.
- Such rolls can also be described as segmented flattened become.
- rollers have the disadvantage that their central axis for the each flat resting of two adjacent shell sections respectively to tilt, which requires a lot of equipment.
- Object of the present invention is therefore to provide a device for soil compaction with at least a vibrating roller, in which the roller has a relatively wide footprint, at the same time has the best possible synchronization and is particularly stiff.
- rollers are significantly improved. simultaneously can with only one roller both the compression and the propulsion or gradeability be realized.
- circumferentially staggered sections have the effect of stiffening the individual segments an even better transmission of the vibrational forces to be compacted To reach soil material.
- corresponding rolls have 2-7 corresponding juxtaposed sections.
- the roller over a step gear to rotate intermittently this step transmission
- a device for detecting a vibration number can be coupled to the directional vibrator. This will ensure that on each floor section on which the roller with a flattened Segment comes to stand, a predetermined oscillation number is applied and thus ensures a desired compression result can be.
- step mechanism to advance the vibrating Roller to couple with a device that has different parameters the soil compaction is determined directly and when a setpoint is reached then the step mechanism activates to continue on next segment.
- the gradeability of the rollers is further improved when the abutting edges of the flattened segments be provided with radially projecting toothed racks, which can also be made of a harder material and so in are able to compensate for the greater wear at this point.
- the compaction device continues with a Smooth coat roller to equip with the undesirable surface structure can be densified and smoothed.
- Preferably These circular sections are close to the axial Ends of the roller provided to the tipping security of the compacting device to increase.
- Figure 1 shows a roller for a soil compaction device in the Side view.
- This roller has a circumferential surface 1, which is in the circumferential direction the roller is composed of four segments 2. These segments 2 collide at edges 3.
- the edges 3 describe a circular arc 4, whose radius of curvature 5 the distance of the edges 3 of the roll axis 6 corresponds.
- the centers 7 describe the Segments 2 a circular arc 8, the radius of curvature 9 the distance the center 7 corresponds to the roll axis 6.
- the mean roller radius 10 is therefore between the radius of curvature 9 of the Centers 7 described circular arc 8 and the radius of curvature 5 of the arc described by the edges 3 4th
- a roller with a cylindrical outer surface causes vibration a ground to be compacted by her not only normal forces but also shear forces, which are very undesirable depending on the soil.
- the segments 2 shown here are flat, i. that they extend in the axial direction of the shaft parallel to the shaft axis and otherwise lie in a tangential plane. This will be from the segment, when resting on compacted soil, only Transmitted normal forces, but no shear forces. This can be done via a Such segment also not necessary for a movement of the roller Forces are applied parallel to the soil horizon.
- a roller is shown, in which over its width a total of five sections 12 and 13 are arranged side by side. These There are sections, as can be seen from the figure 3, at their Lateral surface in each case of eight flat segments 2.
- the flat segments abut each other in the circumferential direction, without while forming an undercut. That is, that shown in FIG Angle 14 on adjacent segments is always less than 180 °.
- FIG. 4 shows a longitudinal section through a roller according to FIG. It can be seen that this has a hub 15 in the middle, the over Hub plates 16 at their axial ends consisting of several segments Lateral surface of the roller bears.
- the individual segments 12, 13 are in the axial direction of the roller over Perforated sheets 17 limited, also recognized on the adjacent segments are offset circumferentially by an angle.
- a directional transducer is installed, wherein after a predetermined number of oscillations over a manual transmission, not shown, the roller to the above-mentioned half angle is further rotated so that another segment, which is then located on the adjacent section, flat on the floor is applied and subjected to vibrations for soil compaction becomes. In this indexing, the roller moves over the abutting edges continue, even on rising terrain etc.
- FIG 6 is a roller with a specially designed type of segments shown.
- the individual segments 18 have a concave Course, i. they are curved in the direction of the shaft axis 6. Because of a Such concave configuration of the segments can be a kind of "focusing" the vibration forces on deeper soil layers achieved become. Here are the most prominent for the movement Edges used 19, which are good for application due to their shape the locomotion of the roller are suitable.
- edges 19 In order to prevent occurring at these edges 19 greater wear, are as shown in Figure 7 can be seen on these edges 19 rack 20 put on, which are made of a more wear-resistant material and so protect the edges 19.
- the toothed strips 20 each extend over the width of a section.
- rollers are proposed, they according to a predetermined Continue to turn the number of vibrations via a manual transmission so as to achieve locomotion and compression in other places.
- FIG. 8 shows a corresponding compaction roller 21 according to FIG of Figure 6 installed in a corresponding compression device 22.
- This compacting device 22 still has another roller 23 on, which is provided with a smooth coat 24. Since the further roller 23 with the smooth coat 24 of the compacting device 22 true to the Compression roller 21 is tracked, is with this further roller 23rd still a re-compaction of the left behind by the compaction roller 21 To achieve surface structure, in which this through the compaction roller 21 generated surface structure through the smooth shell 24th is also smoothed.
- rollers as shown in Figures 1-7, also can still be provided with sections 25, which is a circular cylindrical Have shape.
- sections 25, which is a circular cylindrical Have shape.
- the roller with circular cylindrical sections then as the roller 23 shown in Figure 8, in which therefore instead of Smooth coat 24 also made up of individual sections with flattened Segments composing jacket could be provided.
