DETAILED DESCRIPTION OF THE FIGURES

[0109] For the purpose of easier understanding, the figures are first described together with reference to all the reference signs. Details or special features shown in the respective figures are described individually.

[0110] To erect an embankment or levee or construction works 3 on the soil 80, feedstock 1, which is preferably applied and compacted in individual horizontal strips 2, is used. The construction works is then produced in individual horizontal sections 3.1, 3.2, . . . , 3.12, 3.n, in particular in e.g. five or six horizontal sections per height level zn (here, six horizontal sections per level).

[0111] Firstly, the feedstock has to arrive at the construction site. Material transport units, in particular trucks 4, can be used for this purpose (in particular delivery in batches). By means of a material feeding unit 5, in particular a tripper car, the feedstock can then be fed to a/the feedstock processing apparatus 10 for processing.

[0112] The feedstock processing apparatus 10 comprises a chassis 20 with at least one undercarriage, in particular with a first undercarriage 21, in particular a tracked undercarriage, and a further (second) undercarriage 22, in particular a tracked undercarriage. Several (first, second) traction drives 23, 24 may be provided, each for one of the undercarriages. A frame structure 30 with at least one support, in particular with a first support 31, in particular in a vertical alignment, and with at least one further (second) support 32, in particular in a vertical alignment, preferably each having a height adjusting means 33 with an in particular hydraulic drive/actuator 34, provides a support for a crossmember 35 (support structure or component thereof), on which at least one tool/device is displaceably mounted via fastening means 37, in particular for a translational relative movement. In this respect, the frame structure 30 may be designed in a modular manner from individual modular frame elements 36. The frame structure 30 may further have one or more longitudinal members 38. One or more guides 39, in particular translational guides, may be provided on the frame structure 30, in particular also for the purpose of mounting material flow modules.

[0113] A material feeding device 40 guarantees the material flow from the material transport units 4 up to the application point and, in one of the exemplary embodiments shown here, comprises a first, second and third conveying device 41, 42, 43, in particular each in the form of a conveyor belt, and a first, second and third conveying unit 44, 45, 46, in particular in the form of a trolley or tripper car. A further conveying unit 47 may be designed in particular as a screw conveyor and be provided for the material flow at the application point. A height-adjustable material chute 48 may also be provided.

[0114] A material distributing device 50 guarantees the distribution of the material at the application site and comprises at least one winch 51 and traction means 52 as well as a material distributing unit 53, in particular in the form of or having a 3D printing unit 55. An alignment of the compacting units can be set, optimized or else cyclically continuously adjusted by means of a rotary mechanism 54 (keyword: crab steering). Control steps for crab steering are illustrated e.g. in FIG. 13 (in particular S23, S31, S32, S33, S41).

[0115] A compacting device 60 guarantees the compaction of the material, in particular directly at the application point or just upstream and/or downstream thereof, and comprises a rotary drive 61 or a steering device, at least one compacting unit 63, in particular in the form of a vibratory roller or compaction roller, a grader 65 and at least one drive 66 for autonomous propulsion of the compacting device.

[0116] A control device 70 for controlling/regulating the method is coupled to at least one sensor 71 and comprises a material flow control unit 73 and is configured to activate at least one joint 75 arranged on the material flow path or the corresponding pivot axis.

[0117] The material transfer may take place in particular in three transfer points, in particular with a continuous material flow in each case: first material transfer point P1, second material transfer point P2, third material transfer point P3.

[0118] The method can be described by the following steps: [0119] S0 Material flow from P1 to P3 [0120] S01 Material transfer in P1, in particular by way of continuous pouring [0121] S02 Material transfer in P2, in particular by way of continuous pouring [0122] S03 Material transfer in P3, in particular by way of continuous pouring [0123] S04 Regulating the material throughput during the conveying [0124] S10 Applying feedstock [0125] S11 Regulating the material throughput when the feedstock is being applied [0126] S20 Compacting feedstock [0127] S21 Compacting upstream of the application point for feedstock [0128] S22 Compacting downstream of the application point for feedstock [0129] S23 Actuating, in particular driving/rotating, at least one compacting unit [0130] S30 Propulsion of material distributing device and compacting device [0131] S31 Propulsion in width direction [0132] S32 Propulsion in working direction [0133] S33 Setting the movement path of the compacting unit [0134] S40 Height positioning and height adjustment [0135] S41 Tilt compensation [0136] S50 Setting the application direction and/or longitudinal offset [0137] S60 Propulsion by chassis (traction drive) in the working direction [0138] S61 Propulsion in accordance with the predefined longitudinal section of the construction works to be erected

[0139] The length and size indications are explained below:

[0140] Width direction x, working direction or propulsion direction y, height or height direction z (in particular vertical or direction of gravity). The span width x1 of the apparatus is greater than the working width x2 of the apparatus. The length y1 of the apparatus can be selected with regard to the construction works to be created. The longitudinal extent y2 of the material distributing device/material distributing unit makes it possible to define the width of horizontal strips which can be applied by means of the material distributing device.

[0141] FIGS. 2B, 3B, 4B, 10B, 11B, 12B respectively illustrate the perspective of the apparatuses shown in the corresponding FIGS. 2A, 3A, 4A, 10A, 11A, 12A.

[0142] FIG. 1 shows a frame structure 30 erected over a span width x1 and having one or more crossmembers 35, which is/are supported on two or four supports 31, 32 respectively in an undercarriage 21, 22. FIGS. 7, 8 also show such a constructional assembly, in each case with two oppositely situated longitudinal members 38 extending at least approximately parallel to one another.

[0143] FIG. 2A shows a mounting of the material distributing device 50 in an arrangement encompassing the frame structure 35. This also provides a high degree of safety and can make the mounting stable, even with regard to high moments of inertia.

[0144] FIG. 3A shows a functional integration of the material distributing device 50 and the compacting device 60, wherein the height-adjustable coupling is effected in particular via traction means 52 in a central arrangement below the material chute 48.

[0145] FIG. 4A shows a compacting device 60 comprising two compacting units 63, each rotatably mounted around an individual axis of rotation by means of a rotary mechanism 54, in the form of rollers, wherein the distribution and compaction process can be regulated by means of a screw conveyor 47 and one or more graders 65.

[0146] FIG. 5 illustrates an overlap y3 of the one roller 63 in the advancement direction y. The movement path of the compacting device is aligned in the direction x. The two compacting units 63 are arranged relative to one another with an offset Δy to one another that is greater than the overlap y3.

[0147] The rotary drives 61 and drives 66 of the compacting units 63 are shown in detail in FIG. 6. A material distributing unit 53 is arranged on the material flow path, e.g. in the form of a screw conveyor. The application of the material can be regulated by means of graders 65 or by means of material flow control units 73 mounted around at least one joint 75.

[0148] The arrangement shown in FIG. 7 is characterized by a symmetrical assembly with a rectangular base area and four undercarriages. The longitudinal extent of the member 38 is in the region of approximately one third of the extent of the two oppositely situated crossmembers 35 in the width direction. The material distributing device 50 and the compacting device 60 are arranged between them on a further crossmember 35, which can be displaced in the longitudinal direction. A comparable arrangement, but with only one crossmember 35, is shown in FIG. 8.

[0149] FIG. 9A illustrates the material flow path M1 up to the application point, and likewise illustrates the material flow path M2 defined by the movement path of the material distributing device: the movement path M2 of the material distributing device is meandering here, with points of reversal arranged in a matrix-like manner between respective unidirectional, in particular one-dimensional movements.

[0150] FIG. 9B illustrates individual horizontal strips 2 or horizontal sections 3.1, . . . , 3.6 and 3.7, . . . , 3.12, each applied in the desired layer thickness. In this example, five individual height positions zn are provided above the target height z3 of the construction works, between which height positions a respective y offset is realized, e.g. a y offset corresponding to half the width of the horizontal sections.

[0151] FIGS. 10A, 11A illustrate the material flow using the example of a construction according to FIG. 8. The longitudinal extent y2 is e.g. in the range from 2 m to 5 m. At the three material transfer points P1, P2, P3 there is a respective reversal of direction or change in direction of the movement path and optionally also material buffering. A material transport upwardly in the height direction only has to take place up to the first material transfer point P1 in this case. Further sections of the material flow path are aligned substantially horizontally (at least approximately) on the same height level (apart from any desired height differences at the transfer points P2, P3).

[0152] FIG. 12A further shows a material flow unit 49, in particular in the form of a material chute and/or bunker, by means of which the material flow can be regulated or aligned and/or buffered. Corresponding material flow units 49 can also be provided at further material transfer points (P1, P2).

[0153] FIG. 13 generally describes a mode of operation in which/by means of which a material distributing device and at least one compacting unit (or its movement paths) can be controlled in a manner dependent on one another and dependent on the material flow. Here, the movement path of the respective compacting unit may correspond to the movement path of the material distributing device, and may optionally be further differentiated on this movement path (optional situation-dependent direction/tilt compensation).
