Description

[0001] The invention relates to a device for improving, processing or changing the soil mechanical properties of soils in the amphibious water-land transition zone of bodies of water, soil depressions and soil remediation areas.

[0002] For the improvement, processing, or modification of soil properties, particularly in transition zones with water bodies, as well as in soil remediation projects, improving the soil's bearing capacity is essential to ensure its usability for pedestrian, vehicular, or construction purposes. Especially in the post-mining phase of open-pit mines, stable geotechnical conditions are crucial to prevent subsequent landslides, particularly at the edges. When overburden is dumped, the achievable soil strength depends on the quality of the overburden, meaning that stability across the entire area is not guaranteed.

[0003] To improve soil properties, soil compaction is carried out using vibrators or vibration sources.

[0004] DE 10 2010 022 802 B4 discloses a method and a device for improving the soil mechanical properties of soils using an amphibious hydraulic excavator that rests on the soil to be improved. The connection between the carrier vehicle and the vibration source for soil excitation is achieved via rigid mechanical elements and fixed, single-axis joint connections. This allows the carrier vehicle to exert a pressure force on the vibration source during vibratory compaction, in addition to the source's own weight.

[0005] However, a disadvantage is that the pressure exerted by the carrier device under varying soil conditions and different geological layers, as well as foreign bodies in the soil, poses a risk of damage to the device.

[0006] The task is therefore to provide a device for improving, processing or modifying soil mechanical properties, which overcomes the disadvantages of the state of the art.

[0007] According to the invention, the problem is solved by a device according to the independent claims. Advantageous embodiments of the invention are specified in the dependent claims.

[0008] A first aspect of the invention relates to a receptacle for the detachable mounting of a device for improving, processing, or modifying the soil mechanical properties of soils, comprising at least one soil cultivation unit, to a carrier vehicle. The receptacle for detachable mounting to the carrier vehicle, such as an excavator or other carrier vehicle, has a compensating element designed to ensure at least lateral movement of the soil cultivation unit relative to the carrier vehicle. This prevents damage to the soil cultivation unit in the event of changing soil conditions or foreign objects, such as stones or roots. In particular, this prevents shear forces in the area of ​​the receptacle on the carrier vehicle when using extension devices, such as extension pipes for compacting deeper soil layers.minimized, as is to be expected with a rigid connection between the receiver and extension device.

[0009] Lateral mobility refers to the deflection of the tillage unit relative to the mounting point in relation to the central axis of the mounting point.

[0010] It has also been shown that the application of an additional pressure or tensile force via the carrier device can be achieved without the risk of damage, as is the case with a rigid connection known from the prior art.

[0011] In embodiments of the invention, excavators are used as carrier devices, preferably amphibious, but also floating or land-based excavators, such as hydraulic excavators. Amphibious devices are particularly preferred in the transition zone between land and water.

[0012] In embodiments of the invention, the soil cultivation unit is selected from a vibration source, an earth auger, or a rammer. Preferably, the soil cultivation unit is designed as a vibration source.

[0013] Depending on the water depth and the required compaction depth in the soil, deep vibrators, vibrators for vibratory piling or extraction equipment, or vibratory plates are used as vibration sources. Light vibratory compaction (LRV or LRDV) is preferred. Deep vibrators, which can be electrically or hydraulically driven, are known examples.

[0014] In embodiments of the invention, the compensating element is at least partially formed from an elastic element. The elastic element ensures that the soil cultivation unit has mobility relative to the carrier machine. In this context, an elastic element is understood to be a component of the mounting that undergoes a change in shape or position when a physical force is applied, but can return to its original position or shape after the force is removed. The change in shape or position of the elastic element directly results in the lateral mobility of the soil cultivation unit relative to the carrier machine.

[0015] In embodiments of the invention, the compensating element is ring-shaped. For the purposes of this invention, "ring-shaped" means a circular body with a central opening.

[0016] In embodiments of the invention, the compensating element is at least partially formed from an elastic element, wherein the elastic element is formed from an elastomer. For the purposes of this invention, elastomers are understood to be dimensionally stable but elastically deformable plastics whose glass transition temperature is below room temperature. These plastics can deform under tensile and compressive stress but subsequently return to their original, undeformed shape. In embodiments of the invention, the elastomer is selected from natural rubber, synthetic rubber, polyurethane, elastic thermoplastics, or a combination thereof.

[0017] In embodiments of the invention, the annular compensating element has a hollow cylinder at its center. In other embodiments, the annular compensating element is designed as a bushing.

[0018] In embodiments of the invention, the compensating element is configured to ensure lateral movement of the soil cultivation unit in the range between 0.2° and 30°, preferably between 0.5° and 20°, and particularly preferably between 0.5° and 15°, relative to a longitudinal axis. Limiting this movement is possible, for example, by laterally restricting the mounting using a limiting element. This prevents excessive movement and the risk of inaccurate localization of the vibration source. In embodiments, the limiting element is adjustable. This allows the lateral movement to be adjusted as needed.

[0019] In embodiments of the invention, the compensating element is at least partially formed from an elastic element, wherein the compensating element is designed to absorb compressive loads. This allows compression to be avoided or at least minimized.

[0020] In embodiments of the invention, the compensating element is at least partially formed from an elastic element, wherein the compensating element is configured to absorb vibrations. The vibrations are transmitted by the vibration source, for example, into the extension device and subsequently into the receptacle. The design of the compensating element minimizes or eliminates the transmission of vibrations into the receptacle.

[0021] The compensating element is advantageously designed in such a way that it has an elastic element which can both absorb vibrations and minimize or avoid compression.

[0022] In some embodiments, the compensating element is ring-shaped, and the elastic element is bounded on its upper and / or lower surface by a limiting element. These limiting elements can be designed to attach the compensating element to the receptacle. For example, the limiting elements can have means for attachment to the receptacle, such as threads or holes. The limiting elements can, for example, be made of metal.

[0023] In embodiments of the invention, the compensating element is designed as a pot.

[0024] In embodiments of the invention, the limiting element is disc-shaped. The limiting element rests on the upper and / or lower surface of the elastic element. Preferably, the disc-shaped limiting element has a central opening, which is preferably aligned with the opening of the annular elastic element. Particularly preferably, the opening of the disc-shaped limiting element corresponds to the opening of the annular elastic element.

[0025] In embodiments, the elastic element is limited on the top and bottom by a disc-shaped limiting element.

[0026] In embodiments of the invention, the limiting element is made of a metal or a metal alloy. The limiting element may have openings for detachable attachment to the receiver and / or to an extension element. The openings may be designed as threaded bores or bores.

[0027] In some embodiments, the elastic element and the limiting element are connected by a material-bonded or form-fit connection. Material-bonded connections serve to join parts together by fusion as well as by intermolecular or chemical bonding forces, optionally via additives. In a material-bonded connection between the elastic element and the limiting element, the connection is made by gluing or welding.

[0028] A frictional connection is maintained by the action of frictional forces that arise between the connected parts. These frictional forces occur when a sufficiently large normal force (compressive force) acts perpendicularly on the contact surfaces of the connected parts. In this case, frictional forces therefore act between the elastic element and the boundary element. For example, the boundary element may have a circumferential edge which, upon contact with the elastic element, causes frictional forces between the circumferential edge and the elastic element.

[0029] In embodiments of the invention, the soil cultivation unit is lifted and lowered by the carrier vehicle. This lifting and lowering movement can be continuous or discontinuous.

[0030] Another aspect of the invention relates to a device for improving the soil mechanical properties of soils, comprising at least one soil cultivation unit, at least one extension device, and a receptacle according to the invention for detachable attachment to a carrier device. The device represents the entire assembly from the receptacle to the soil cultivation unit and also includes an extension device, such as an extension tube.

[0031] In embodiments of the invention, the device includes sensors for recording at least one parameter selected from the position, depth of the tillage unit, time, and working pressure of the tillage unit. Recording these parameters enables digital recording of the tillage process, with precise localization of the tilled soil areas achieved by recording the position, for example, using GPS. This is particularly advantageous for assessing the stability of soil areas during the post-treatment of spoil heaps or riparian zones.

[0032] Another aspect of the invention relates to the use of a receptacle according to the invention for the detachable arrangement of a device according to the invention on a carrier device.

[0033] The invention is not limited to the embodiments shown and described, but also includes all embodiments that have the same effect within the meaning of the invention. Furthermore, the invention is not limited to the specifically described combinations of features, but can also be defined by any other combination of certain features of all disclosed individual features, provided that the individual features are not mutually exclusive, or a specific combination of individual features is not explicitly excluded. Examples of implementation

[0034] The invention will now be explained in more detail using several exemplary embodiments. The exemplary embodiment relates to a recording according to the invention and is intended to describe the invention without limiting it.

[0035] A first embodiment describes a receptacle 1 according to the invention for the detachable arrangement of a device for improving, processing, or modifying the soil mechanical properties of soils. The device 2 comprises at least one soil processing unit 3, for example, a vibration source, which is detachably arranged on a carrier device 4, such as an excavator or similar, by means of the receptacle 1. The vibration source 3 is, for example, designed as a hydraulically driven vibrator. The detachable arrangement is effected, for example, by means of a bolt 5. Furthermore, the receptacle 1 includes a compensating element 6, which is configured to ensure lateral movement of the vibration source 3 relative to the carrier device 4. The compensating element 6 acts as a connecting element between the receptacle 1 on the carrier device 4 and the vibration source 3.In most cases, at least one extension device 7, such as an extension tube (not shown in detail), is provided between the compensating element 6 and the vibration source 3. The compensating element 6 is annular and at least partially formed from an elastic element, which is made of an elastomer. The elastic element allows tensile and compressive loads as well as lateral movement of the vibration source 3 in the range between 0.2° and 30°, preferably between 0.5° and 20°, and particularly preferably between 0.5° and 15°, relative to a longitudinal axis of the extension device 7.

[0036] In another embodiment, the compensating element 6 has a socket. The socket allows, for example, the passage of cables to the soil cultivation unit 3.

[0037] In a further embodiment, the compensating element 6 is ring-shaped, with the elastic element being bounded on its upper and / or lower surface by a limiting element 8. The limiting element 8 is disc-shaped. The limiting element 8 rests on the upper and / or lower surface of the elastic element. The disc-shaped limiting element 8 has a central opening that is aligned with the opening of the ring-shaped elastic element.

[0038] In another embodiment, the limiting element 8 is made of a metal, such as steel or a metal alloy. The limiting element 8 has openings for detachable attachment to the receptacle 1 and / or to an extension element 7. The openings are designed as threaded bores or bores.

[0039] In another embodiment, the limiting element 8 and the elastic element are joined together by welding. This results in a compact component that exhibits the elastic properties of the elastic element and is also designed for detachable assembly via the limiting element 8.

[0040] In another embodiment, the mounting 1 is arranged on a carrier vehicle 4, such as an amphibious hydraulic excavator. The soil cultivation unit 3, for example a vibration source, is detachably attached to the mounting 1 via an extension device 7. Through continuous or discontinuous lifting and lowering movements of the carrier vehicle 4, compaction or cultivation in the soil area is achieved by the introduction of vibrations or other forces, such as drilling forces.
