Description

The invention relates to a method for producing a bedding, a device for producing a bedding and the use of a device, the bedding being provided in particular for a line body of a line structure.

When creating base bedding for long-standing objects in a building, there is a difficulty in achieving a high level of positional accuracy with uniform compaction. Usually, such elongated objects are placed on a prepared, possibly pre-compacted planum, then filled on both sides with a backfill material and / or covered. Depending on the type and layer thickness of the backfill material, compression processes take place in between.

Often, such elongated objects have a rounded, in particular oval, cross-sectional geometry. In the case of complex cross-sectional geometries, for example those which deviate from a simple geometric basic shape, in particular with flat surfaces such as, for example, a rectangle or trapezoid, the generation of a uniform compression over the entire circumference of the cross-section is very complex. In particular, an insufficient density in the area between the fighter and the sole, called the gusset, can lead to a positional instability of the object in later artificial or natural compression processes and / or to strong tensions and deformations of the object.

From the publication DE 100 46 299 C1 A method for producing a bedding is known in which, after creating a trench bottom, a pipe section is placed on the finished pipe bedding in accordance with the outer contour of a pipe to be laid. The profiling plate is attached to an excavator boom and is moved by the movement of the excavator. The publications describe a similar prior art DE 10 2010 021 335 A1 and DE 199 40 875 C1 ,

The publication DD 125 149 A1 discloses profiling a trench bottom after conventional trenching. The publications also go in a similar direction US 3,638,438 A1 and DE 26 03 565 C2 , in which the device has means for supporting the trench walls, which remain in the trench section until it is filled again via an inserted pipe section.

By optimally compressing the flanks, especially in the area of the gusset, the object laid in the trough is very well stabilized in its lower cross-sectional section or cross-sectional half. This prevents unwanted deformation or displacement of the object. Any damage to the object due to cavities directly under the object or due to poor density or compaction of the soil material is excluded.

Long-standing objects are not only to be understood as strip foundations. The invention aims in particular at the installation of a line body of a line structure in the ground. Here, a pipeline structure is to be understood to mean any form of structure for transport over long distances. These can be pipelines for fluids, but also electrical cables or cladding and empty pipes for cables.

Another aspect of such objects is that, depending on the task, they require a defined thermal connection to the floor surrounding the object. It may be necessary to ensure that a defined heat flow into the floor is required to cool the object or that a defined insulation and / or insulation of the object is to be achieved to protect against heat loss from the object. In this case, an uneven compaction of the soil around the object is disadvantageous. Individual zones of insufficient compaction or even imperfections, especially in the area between the fighter and the sole of the object, the so-called gusset, lead to an uneven connection of the object to the surrounding ground. This can result in locally undesirable thermal loads or stresses in the object.

Such gussets can be found in all objects in which the widest cross section is not in the sole, as is the case with oval or round cross sections, for example in the case of pipe or cable lines.

The invention has for its object to provide a method and a device that a bedding can be generated, which enables a line body with a high positional accuracy and / or positional stability and / or uniform compaction in a building ground. In particular, it is possible to fix the object to be installed in the building ground over its entire length in its exactly desired position.

This object is achieved with the features of claims 1 and 6 and 10. The further dependent claims relate to particularly preferred embodiments of the invention. The individual features of the invention are explained below.

According to the invention, a method is provided for producing a bedding, in particular for a line body of a line structure. In this method, a displacement sign is placed on the surface of a floor section in one process step and the displacement sign is moved along an elongated distance over the floor section in a subsequent process step. The displacement plate engages at least one profiling section of the displacement plate in the ground below the surface. This intervention and the movement of the displacement shield displaces a subset of the soil below the surface from at least the profiling section. This results in at least one longitudinally extending depression in the bottom section along the route.

With the proposed method, in particular for the bottom area of an object, such as a line body, a profiled bedding adapted to the object can be produced. The object can be embedded, in particular inserted or drawn in, into this bedding, which is referred to as a trough. The trough can either be made compressed or not. A drawn or guided displacement plate is used as a profiling template. The displacement plate can be equipped with hand-operated or machine-operated compressor units.

According to one embodiment of the method, it is provided that the bottom section is prepared before the displacement shield is placed on the bottom section.

With such a preparation, a bed of stones is created from stone-free, preferably fine-grained material. The bed of the bed is produced as a particularly undensified subgrade. After such preparation, the floor section is designed as a subgrade.

It is also possible to carry out an at least partial compaction of the base section before the displacement shield is put on. The preparation is preferably done by machine.

The at least one trough preferably has a uniform cross-sectional geometry, which is achieved in that the working profile of the displacement shield, in particular the profiling section, is unchangeable and its orientation with respect to the direction of movement is not changed.

By adjusting the working profile and / or the orientation of the displacement shield, in particular the profiling section, alternative embodiments make it possible to produce a trough with a continuously or continuously changing cross-sectional geometry over its longitudinal extent during the movement of the displacement shield.

The method further provides that a line body is positioned in the trough immediately following the displacement shield. This ensures that the trough flanks and the line body support each other. At the same time, a high accuracy of fit is achieved by using a shape of the displacement shield, in particular the profiling section, which is matched to the cross-sectional shape of the line body. This leads to an excellent positional securing of the line body and, especially below the line body, to an even bedding in the ground.

The use of a shape of the displacement shield which is matched to the cross-sectional shape of the line body is not restricted to the above method step. In a supplementary or alternative method step, the method provides for the soil to be compacted at least by the profiling section of the displacement plate, so that a trough with stable and / or load-bearing flanks is created. This ensures that the soil is compacted before the object is introduced into the trough, in particular below the object. This compaction can take place by displacing the soil from the trough space into the trough flanks and / or by applying forces to the soil, in particular to the cross section of the trough.

The term “bottom section” is to be understood as a possibly prepared and / or pretreated, preferably flat section of the earth's surface to which the method according to the invention is applied or which is processed with the device according to the invention.

The term longitudinal extension describes an embodiment which has a much greater extent in a longitudinal direction, the main direction of expansion, than in all other directions, in particular oriented transversely to the longitudinal direction.

The flanks of the trough are all side surfaces delimiting the trough. All surfaces forming the trough in the floor, irrespective of their spatial orientation, are also considered the side surfaces, including the trough bottom designated as the trough sole.

The term stable in this context indicates that the floor next to the trough can bear its own load permanently without that this falls or slips into the trough created. The term load-bearing means that the floor, in particular the areas of the surface of the floor section adjoining the trough, can bear an area load that exceeds the dead load of the floor.

Depending on the sole material used, the trough is compressed to such an extent that, after the compression, the flanks, in particular the trough base, can carry the object to be accommodated in the trough without further deformation and / or compression.

The compacting of the soil to stabilize the trough and / or to produce the trough takes place, as mentioned above, by displacing the soil into the flanks and / or by applying force to the soil. The force is preferably exerted on the flanks of the trough, but can also take place additionally or alternatively on the surface of the base section adjacent to the trough. This achieves a good design of the trough with the desired cross-sectional shape.

It is possible to implement different forces via the cross section of the trough, for example a high force acting on the side surface forming the trough base and a lesser force acting on the side surfaces which are arranged closer to the surface of the base section. However, it has proven to be advantageous for the force to be applied uniformly over the cross section of the trough. This can in particular be achieved solely by means of a vertical force of the displacement shield, in that the displacement shield at the same time displaces soil sideways into the flanks. This displaced floor redirects the vertical force at least partially and in sections into a horizontal force. So the displacement together with a horizontal force component over the entire cross section of the trough creates a uniform compression.

The process explained above is supported in particular by a profiling section of the displacement shield, the cross section of which tapers towards the bottom, for example in the case of a cross-sectional shape which resembles a circular section.

If, in addition to the trough, the surface of the bottom section is also compacted, it is provided that the profiling section of the displacement shield engaging in the bottom provides the compression in the region of the trough and part of the remaining displacement plate, in particular a flat body, acts on the surface of the bottom section.

The action of force described above can take place statically, for example through the dead weight of the displacement shield, and / or dynamically. Dynamic compression is usually achieved by vibration. The force of the displacement shield preferably has a vibration that oscillates in the vertical direction. In addition, it is also possible for the displacement plate to introduce a horizontally oriented vibration into the floor, in particular into the flanks of the trough. The horizontally oriented vibration is preferably oriented transversely to the longitudinal extent of the trough. To generate the vibration, the displacement plate has at least one vibration generator.

An immediately following line body is to be understood to mean that the line body is pulled through the trough by the displacement plate or an attachment to the displacement plate with the movement of the displacement plate or is inserted into the trough.

To pull the line body into the trough, the line body is fastened to the displacement plate, in particular to the profiling section. A line body detachably connected to the displacement plate in this way is pulled into the trough and / or through the trough with the movement of the displacement plate. The line body is thus moved with the displacement plate relative to the floor in the direction of movement of the displacement plate. This is advantageous since, immediately after the production of a cross-sectional shape of the trough that is ideally matched to the cross-sectional shape of the line body, mutual support of flanks and line body is achieved.

By pulling in one or more line bodies directly with the displacement plate, it is possible that further work steps, such as the separate installation of one or more line bodies, can be saved.

Two different procedures are conceivable for insertion into the trough. In one approach, the line body could already be designed as largely as possible parallel to its final position on the base section, in order then to be picked up by the displacement plate or an attachment on the displacement plate and, if necessary, to be guided over the displacement plate and finally into the trough produced by the displacement plate to be inserted. In the other method, the line body is transported by the displacement plate or a vehicle accompanying the displacement plate in its movement or a vehicle guiding the displacement plate. The line body is wound on a reel, for example. The The lead body is then provided with the progress of the movement of the displacement plate and inserted into the depression by the displacement plate or an attachment on the displacement plate. In both of the above-mentioned procedures, the line body deposited in the trough is no longer moved. The attachment and or the displacement plate has a guide section which guides the line body into the trough.

If the floor is compacted by the displacement plate in such a way that a trough with stable and / or stable flanks is created, it is possible to position the line body in the trough at a later time. The time period between the production of the trough and the time of installation of the line body is preferably several days long. The length of the time period essentially depends on the weather and further on on the material of the bedding material in the floor section and partly also on the degree of compaction and the load-bearing capacity of the floor.

Here, as a further method step, it is provided that, in the case of a trough with stable and / or stable flanks, the displacement plate is removed from at least a section of the trough, preferably completely from the trough, then the trough in the section is free over a period of time, in particular also is kept free of support means, and after the period of time a line body is positioned in the trough. This enables the individual construction processes to be decoupled. It is also possible to check the dimensional accuracy of the compression after the compression.

As a final method step, it is provided that the floor section and the line body positioned in the trough are covered with further floor material and the further floor material is compacted. This creates a uniform compaction of the soil around the line body.

The displacement plate can be moved in such a way that the displacement plate moves independently over the bottom section. For this purpose, the displacement plate has a chassis, for example. However, it is also possible for the displacement plate to be pulled or pushed or guided over the floor section by a movement device. In this context, the term guide means that the displacement plate is moved along the route by the movement device and is held above the base section in such a way that the displacement plate, in particular as a result of the movement of the displacement plate, has no or only slight horizontal forces, in particular in the direction of movement, in the Soil.

An independent movement of the displacement shield can also be achieved by a horizontally oriented vibration, which is aligned parallel to the direction of movement.

According to the invention, a device is provided for producing a bedding for the floor, in particular for a line body of a line structure. The device has a displacement plate with a flat body and at least one profiling section. The flat body has an underside which faces and is assigned to the soil to be worked. The sheet also has an upper side that is opposite the lower side and faces away from the floor. The at least one profiling section is skid-like and is formed on the underside of the sheet. The profiling section is raised relative to the flat body, in particular extends distally in the direction of the floor.

Unless otherwise stated, all directions refer to the correct use of the device and the intended orientation of the displacement plate.

The profiling section is preferably elongated and oriented with its longitudinal axis parallel to the direction of movement of the displacement shield. As a result, a uniform surface pressure can be achieved over at least part of the length of the profiling section. It is also possible for part of the profiling section to convey soil out of the trough profile or to compact it into the flanks of the trough. Finally, part of the profiling section can serve as a support for the trough and / or as an insertion aid for the line body.

According to a further embodiment of the device, it is provided that the displacement plate has at least one vibration generator. The sheet is preferably designed as a vibration compressor, the vibration generator being arranged in the sheet or on the top of the sheet.

Alternatively or in addition, the displacement plate can have at least one receptacle for a vibration compressor, in particular as a separate, independent device. Such a receptacle is preferably provided on the top of the sheet and comprises fastening means for releasably connecting the vibration compressor to the displacement plate. Such a vibration compressor can be, for example, a vibration plate compressor.

A further advantageous embodiment of the device provides that at least one mass body is detachably arranged on the displacement plate. The at least one mass body is preferably arranged on the upper side of the surface body. The mass body or bodies can be designed, for example, as a vibration compressor.

It has proven to be particularly advantageous that each profiling section is covered by at least one mass body. As a result, the vibration applied by one or more vibration generators can be transmitted uniformly into the profiling sections.

The mass of the device, in particular of the displacement shield with the vibration compressors and / or mass bodies, is preferably distributed uniformly, particularly preferably symmetrically, over the cross section of the displacement shield.

A further design of the device provides that the displacement plate has a displacement body for each profiling section. These displacement bodies are arranged in front of the profiling sections in the direction of movement of the displacement shield. Each of the displacement bodies has a cross-sectional geometry that is tapered towards its distal and / or an axial end. The distal end is the section of the displacement body that points to the floor when the displacement shield is used. An axial end is the section of the displacement body which lies in the direction of movement of the displacement shield at the front, in particular in front of the profiling section of the displacement body or at the rear, behind the profiling section. The displacement body and the profiling section are preferably produced in one piece or the displacement body is integrally formed on the profiling section in a manner that is flush with the contour. In these cases, the front end of the profiling section and the rear end of the profiling section form the axial ends of the displacement shield.

The device has a movement device, by means of which movement of at least the displacement shield is made possible in at least one direction of movement. The displacement plate is moved, for example, by means of vibration. The vibration is oriented horizontally and parallel to the profiling section and / or the longitudinal path. The movement can also take place by means of a wheel or caterpillar drive. For example, the device can be self-propelled and can have a wheel or caterpillar drive for this purpose. It is also possible for the displacement plate to be detachably attached as an attachment to a self-propelled construction machine. For example, construction machinery such as excavators, wheel loaders, pavers or caterpillars can be provided as the movement device. The displacement plate is then moved with the construction machine. Furthermore, it is also possible for the displacement plate to be moved by a stationary movement device, for example a construction machine, by means of a chain or cable pull.

It is preferably provided that the displacement body, in particular the ventral end of the displacement body which is further forward in the direction of movement of the displacement shield, is conically shaped. This enables a particularly strong and even compaction of the soil into the flanks. According to a further embodiment, it is provided that the distal end of the displacement body and / or the transition from the displacement body to the profiling section is positioned below a mass body.

Another embodiment of the device provides that the front, ventral end of the displacement body is configured so as to point in the direction of movement of the displacement shield at the bottom. This makes it possible to raise soil and / or to convey it out of the trough.

According to one embodiment, the displacement body has a ridge in the middle on its upper side. This ensures that the raised and / or conveyed soil is deposited evenly on both sides next to the displacement body. According to another embodiment, the displacement body is designed and configured, in particular together with the profiling section, to displace and compact floor material downwards and into the flanks. It is also possible for the displacement body to convey a part of the base material out of the trough and to displace and compact another part of the base material into the flanks, that is to say it is realized as a combination of the two aforementioned embodiments.

According to a further embodiment, the profiling section guided in the trough has at its free end pointing against the direction of movement a rear extension which is oriented upwards and / or towards the center of the trough, that is to say is configured away from the flank flanks. This ensures a clean sliding without damaging the flanks.

At the rear of the profiling section and / or at the rear extension of the profiling section, the distal end preferably extends further back than a proximal section of the profiling section.

A special configuration of the profiling section and / or the Displacement shield provides that the profiling section and / or the displacement body, at least their distal ends, are vertically adjustable. This makes it possible to adapt the displacement plate to different trough depths, soil types or compaction dimensions. A further development of this embodiment provides that the profiling section and / or the displacement body can also be adjusted in width. It is also possible for the displacement body or the rear extension to be adjustable in their vertical and / or horizontal alignment.

The profiling section and in particular also the displacement body can have different shapes. A circular section, in particular a semicircle, has proven to be particularly suitable. However, other cross-sectional shapes are also possible and may be more advantageous. For example, oval cross-sectional shapes are suitable for narrow, deep troughs and flat, wide troughs; cross-sectional shapes with flat edges are ideally designed such that roundings are provided in the corner regions between two edges. Polygonal cross-sectional shapes are possible, as are wave-like cross-sectional shapes.

For the introduction of the line body, it has proven to be advantageous that a fastening section or a sliding body is provided at the dorsal end of the displacement shield, in particular on the profiling section, in particular on the rear extension. A line body can be attached to the fastening section and thus pulled into the trough with the movement of the displacement shield, or pulled through the trough. Alternatively, a line body can be let into the trough via the sliding body, so that, in contrast to the displacement plate, the line body is not moved relative to the floor in the direction of movement of the displacement plate. Here, the line body is either unwound from a reel and / or fed laterally. However, it is also possible for the line body to be lifted up and / or underneath by the displacement plate.

According to the invention, the use of a device is provided in which a base bed, in particular for a line body of a line structure, is produced, the groove in the base bed being used to produce a groove-shaped, longitudinally trough with a uniform cross-sectional geometry.

According to the invention, a line body is understood to mean, for example, a pipe of a pipeline or a cable or a group of a plurality of combined cable runs as an electrical or optical supply or communication line or a cladding or training pipe for any installation.

The described method and the described device make it possible, in particular in the case of a device-guided manufacture of the trough, to attach one or more objects directly to the displacement plate and / or profiling template and to pull them into the profile of the trough during the manufacture of the trough.

Advantages result from the invention, inter alia with regard to the positional stability, the positional accuracy and the compression in the gusset area between the fighter and the sole of the object to be installed. Because the compaction of the soil material is optimally guaranteed in the invention. Sags in the trough, i.e. the bedding of the property, can be prevented in this way. This applies both to a trough that is made compact and to a trough that is made uncompressed. After the object has been installed and at least one layer of further soil material has been installed, an undensified depression is evenly compacted together with the additional soil material by the intended application of force, that is to say mechanically, or by settlement.
