From the prior art, it is known to introduce such Rammpfähle means of a dredged ramming head, ie a hammer and a hammer, in the ground. The ram head is a kind of hammer device which is attached to a boom of the excavator.

Since the driven pile must always be loaded with force along the driving direction during insertion, the driving head must always be held vertically above the pile to be driven into the earth, which places high demands on the guidance of the boom of the excavator used and therefore requires trained or long-learning personnel , In addition, in the known from the prior art method for driving in the ramming piles extensive staff needed. For example. to attach the piles to the excavator and to bring it to the correct position for ramming. Usually, an entire strand of piles at a position in the soil or the soil is introduced. On a first pile, as soon as it is completely introduced into the ground, a subsequent pile pile is placed and Both piles are introduced into the soil by forces applied to the following pile. As a result, a plurality of pile piles can be inserted one behind the other in the ground. Usually, the ramming piles have at one of their ends a sleeve for receiving the respective subsequent driven pile.

The object of the present invention is to provide a piling device which operates safely and increases the speed with which the piles to be brought into the ground can be driven into the ground in a construction site.

The placement of the additional pile from the ready position to the pile position is automated by the feeder. As a result, the speed of driving in the piles is drastically increased and reduced the labor costs for driving in the piles. As a result, a total of costs are saved because the piling device requires less staff at a higher speed. In addition, a high level of operational safety is ensured, since no personnel performs directly on or under the pile performs, but can run all the necessary workflows automated.

It is advantageous if the magazine device can accommodate several other piles in the respective staging positions, so that, for example, six or seven pile piles in the magazine device can be accommodated in a respective supply position and a pile pile after the other via the feeder each can be brought into a Einrammposition and then rammed into the ground.

In the embodiment just described, the piling device as part of the holding device on a gripping device, this gripping device is designed such that it forms the feeder, so remove piles from the staging position in the storage device and can transfer into the Einrammposition.

It is particularly advantageous if the gripping device can refer to the respective further driven pile from the ready position by pivoting towards the magazine device. This represents a cost-effective, safe and efficient way of realizing a feeder.

The sleeve-like storage device serves to precisely place the bottom end of the pile and to guide over the contact rollers. The contact rollers allow a relative movement between the bearing device and the driven pile along the driving direction. However, the contact rollers prevent that the driven pile moves in a radial direction, so quasi breaks out of its intended driving direction.

About the membrane unit and / or the spring unit, the contact rollers can be moved to the pile and can contact them safely. As a result, the driven pile can be guided in a simple and safe manner along the driving direction, so that the driving operation can always be controlled and carried out in a precisely predetermined direction. This also allows very accurate pile logs, which provide information about the soil conditions at the point where the pile pile in the ground is rammed. For this purpose, for example, the penetration rate is recorded, so that can directly during the pile production of the different storage densities in the ground co-determine, which are responsible for how long the pile located in the ground must be in order to be securely anchored.

It is also advantageous if the piling device has a logging unit which records how large the penetration speed per meter of pile is and connects this to the respective position at which the pile pile was introduced into the ground. It is particularly advantageous if the protocol device is executed tamper-proof, so that the created Rammprotokolle can not be manipulated. As a result, a reliable and for example. Quality assurance measures, detection of the stability of the pile or billing purposes required logging of the construction process is ensured.

It is meant by a force orthogonal to the gripping direction that the force exerted on the clamping surfaces has a component which is orthogonal to the gripping direction, so that this force does not act exclusively in the gripping direction. As a result, the driven piles can be "caught" in an advantageous and simple manner and taken up in the magazine racking device and held in the ready position. If the clamping surfaces are relieved of the force acting orthogonally to the gripping direction, they open and release this driven pile.

As a result, the removal of the driven pile from the respective magazine grab device is made possible in a simple manner. It is advantageous if the magazine racking device is biased in the open position, in particular by a spring. This facilitates the removal of a ram pile held in the magazine racking device. In addition, it makes it possible in a simple way to grasp further ramming piles through the magazine gripping device.

It is preferred if the pile shoe providing unit between the pile shoe storage and the bottom of the pile is pivotable so that they can bring the pile shoe from the pile shoe storage by pivoting under the Rammpfahl einzurammenden. The pile shoe provision unit can be designed, for example, as a pivotable plate or as a rotating disc with recesses. Different pile shoes can be used.

Pile shoes with a diameter corresponding to the diameter of the pile can be used if the pile is initially hollow and later filled with mortar or concrete. If the pile is to be surrounded with mortar or concrete in the soil, a pile shoe is alternatively used, which has a diameter which is greater than that of the pile pile.

The pile shoe propelled during the drilling operation creates an annular space hole in the ground which is larger than the diameter of the pile pile. The cavity between the pile pile and the perforated wall is pressed or filled during mortising with mortar or concrete. In this case, a pile shoe is attached to a strand of piles only on the first pile. All other pile piles of a pile pile string are then inserted into a socket at the top of the previous pile pile. So a strand of virtually any (depending on the nature of the soil) many piles are introduced into the ground.

It is also advantageous if the piling device comprises a separating unit with a separating means for separating a piling pile partially introduced into the ground, the separating means preferably comprising a rotatable cutting disk. After reaching the final depth of the pile of, for example, 30 m for a Rammpfahlstrang this does not necessarily correspond to the end of the currently in Einrammvorgang Rammpfahls, so that it protrudes from the ground. The pile must then be separated at a planning height.

In FIG. 1 carries a piling device as a whole the reference numeral 10. The piling device comprises a hammer device 12 which is operable via a hammer drive 14. Along a driving direction 16, which is represented by an arrow and a dashed axis, a driving pile 18 is shown below the hammering device 12 in a Einrammposition EP.

The driven pile 18 comprises an elongate shaft portion 20 and a sleeve portion 22 arranged on the hammer device side. In the region of the sleeve portion 22, the driven pile 18 is held in the driving position by means of a gripping device 24. The gripping device 24 forms together with a cuff-shaped bearing device 26, a holding device 28. The bearing device 26 will be described later with reference to the FIGS. 17 and 18 further described in detail.

The piling device 10 also includes a carriage-like guide means 30. On the guide device 30, the hammer device 12 with its drive 14 and the gripping device 24 along the driving direction 16 are arranged movable. Likewise movable along the guide means 30, the bearing means 26 is mounted.

In the present case, a ramming device-side pivotable and rotatable coupling device 32 is arranged on the guide device 30, which can be coupled to a quick coupling device 34 of, for example, an excavator, wherein this excavator-side quick coupling device 34 is presently shown on a partially illustrated excavator boom 36. The guide device 30 is in contact with a floor 40 via a foot element 38 and is pivotable in all directions via the excavator boom 36.

On the piling device 10, a pile shoe providing unit 42 is arranged on the bottom side, which is shown in two positions, wherein a lowered position is shown by a dashed line. On the pile shoe providing unit 42, a pile shoe 44 is held. Prior to driving the pile 18 into the ground 40, the pile shoe providing unit 42 is lowered and the pile shoe 44 is placed on the floor 40. The shaft portion 20 of the driven pile 18 is then inserted with its bottom end in the pile shoe 44 and the pile shoe providing unit 42 moved out below the pile 18, the pile shoe 44 remains on the pile pile 18 before the Einrammvorgang begins.

Above the pile shoe provision unit 42, a separation unit 46 is arranged on the bearing device 26, which comprises a separating means 48 that is presently designed as a rotatable cutting disk 48. A soundproofing contributes in FIG. 1 the reference numeral 50 and is shown schematically. On the soundproof device 50 will be later with reference to the FIGS. 6 to 8 and 11 to 14 further elaborated in detail.

Subsequently, the Einrammvorgang is described with respect to the driven pile 18. Is the pile 18 in the Einrammposition as in FIG. 1 shown, it is lowered in this position along the driving direction 16 to the bottom 40 and inserted into the pile shoe 44. The pile shoe 44 then sits on the floor 40. During this entire time, the driven pile 18 is held by the gripping device 24 and the bearing device 26 in its ramming position along the driving direction 16.

At the beginning of the Einrammvorgangs the hammer device 12 starts driven by its drive 14 with a sudden impact of the driven pile 18 with forces that drive the pile pile 18 and thus the pile shoe 44 in the bottom 40. The forces are exerted by the hammer device 12 on the sleeve portion 22 of the driven pile 18. The in FIG. 1 Pile shoe 44 shown has a diameter which is greater than the diameter of the shaft portion 20 of the driven pile 18. This results in a ring-shaped hole in the bottom 40, which has a diameter corresponding to the diameter of the pile shoe 44. One wall of the hole in the bottom 40 is thus spaced from the shaft portion 20 of the driven pile 18, thereby forming an annular cavity. This annular cavity is simultaneously with the Impact the pile with mortar or concrete pressed. Distance can be filled in a subsequent step with mortar or concrete.

However, the piling device 10 according to the invention can also be used with pole shoes 44, which correspond to the diameter of the pile 18, so that no distance between the wall of the hole in the bottom 40 and the driven pile 18 is formed. If the first driven pile with the pile shoe 44 is completely sunk in the ground 40, a further driven pile 54 is required. To provide a further driving pile 54, the magazine device 52, which is in FIG. 2 , which is a top view of the in FIG. 1 shown piling device 10 shows.

In the magazine device 52 further ram piles 54 are each received in a ready position BP. Each of the further ramming piles 54 is via a self-tapping magazine magazine 56, of which in FIG. 2 not each bearing a reference numeral held in a respective staging position BP. The self-gripping magazine magazine 56 are each movable along a circumferential path 58.

At the in FIG. 2 shown magazine device 52 while two of these circumferential tracks 58 are provided. The gripping device 24 simultaneously forms a feed device 60, since it can transfer the further ramming piles 54 from its provision position BP in the magazine device 52 into the Einrammposition EP. This will be with reference to the FIGS. 5 to 8 later discussed in detail.

In FIG. 3 one of the circulating tracks 58 is shown in detail. The revolving web 58 has two drive units 60 designed as rotatable wheels, the rotatable wheels can be rotated arbitrarily along a direction of rotation 62. By the rotation of the rotatable wheels 60, a belt-like rail unit 64, which may also be formed as a chain, is moved in accordance with the rotation of the drive unit 60. Attached to the track unit 64 are the self-tapping magazine racks 56, which in turn hold the further ramming piles 54 of their respective deployment position BP.

An upper portion of the piling device 10 from FIGS. 1 and 2 is in FIG. 4 shown in a front view, wherein the soundproofing device 50 is not shown. In the FIGS. 5 to 8 the transfer of a further pile pile 54 from the provision position BP into the Einrammposition EP is illustrated. For clarity, only in FIG. 5 both circumferential tracks 58 of the magazine device 52 shown. In FIG. 5 the magazine racking device 24 is empty and the soundproofing device 50 is closed. A further pile pile 54 to be removed is identified by a reference symbol. About the circulating path 58 moves to be taken further Rammpfahl 54 in its ready position BP to the gripping device 24 out. This position of the further pile 54 is in FIG. 6 shown.

The gripping device 24 has a first joint 62 and a second joint 64, via which the gripping device 24 can be tilted in each case to one side with respect to the guide device 30. The gripping device 24 can therefore be tilted on both sides via the two joints 62, 64. The soundproofing device 50 has an openable and closable access opening 66, which in the present case is implemented via two hinge elements 68.

In FIG. 6 the access opening is shown in the open state. In FIG. 7 It is shown how the gripping device 24 pivots about their first joint 62 to the removal of another ram pile 54 and this attacks. In FIG. 8 is shown as the gripping device 24 is pivoted back and the soundproofing device 50 and its access opening 66 is closed again. The previously further pile pile 54 is now in the Einrammposition EP and represents a Rammpfahl 18 to be eingurammenden.

The following are with reference to the Figures 9 and 10 the self-tapping magazine magazine device 56 explained in more detail. Figures 9 and 10 show such a self-tapping magazine magazine 56 each in a semi-transparent schematic representation. The magazine grip device 56 has an anchor point 70, via the anchor point 70, the magazine grip device is connected to the magazine device 52.

The magazine gripping device 56 also has a first element 72 with a first clamping surface 74 and a second element 76 with a second clamping surface 78, wherein the second clamping surface 78 is pivotally mounted on the second element 76 via a hinge 80.

In FIG. 9 the magazine catcher 56 is shown in a first, open position O and in FIG FIG. 10 in a second, gripping position G. In the second gripping position, the clamping surfaces 74, 78 are displaced toward one another along a gripping direction 82. The anchor point 70 is displaceable relative to the first element 72 and the second element 76. If a force acts orthogonal to the gripping direction 82 on one of the clamping surfaces 74, 78, then the corresponding first element 72 or second element 76 shifts relative to the anchor point 70 and the clamping surfaces 74, 78 shift along the gripping direction 82 towards each other.

The magazine catching device 56 is biased by a spring 84 in the open position O. If, therefore, a further driven pile 54 is gripped by the magazine catching device 56, then the further driven pile 54 is inserted between the clamping surfaces 74, 78. The further driven pile 54 then rests on one of the clamping surfaces 74, 78 and the magazine catching device 56 is pulled back over the anchor point 70. The further driven pile 54 then exerts a force orthogonal to the gripping direction 82 on the clamping surface 74, 78 contacting it.

As a result, the magazine catching device 56 engages as described above, since the anchor point displaces relative to the first element 72 and the second element 76, respectively, and the clamping surfaces 74 and 78 displace towards one another, thus contacting the driven pile 54 to a greater extent and effectively grabbing it. In this case, the clamping surfaces 74, 78, the stronger, the higher the weight of the driven pile 54. If the driven pile is pushed towards the anchor point 70, then the clamping surfaces 74, 78 open and the driven pile 54 can be removed from the magazine catching device 56.

FIGS. 11 and 12 show soundproofing devices 50 from the FIGS. 1 . 2 and 5 to 8 in detail. In this case, the magazine device 52 and, for example, gripping device 24 in the illustration of FIGS. 11 and 12 not shown to ensure a clear presentation. FIG. 11 represents a side view of the soundproofing devices 50. Stands 83 are provided to enable a safe and harmless parking the piling device.

It can be seen that the hinges 68 extend along the entire extension of the soundproofing device 50 in the direction of the driving direction 16. In FIG. 12 is the closable access opening 66 with solid lines shown in the open state and with dashed lines in the closed state.

FIG. 13 shows an alternative embodiment of the soundproofing device 50, which from the in the FIGS. 11 and 12 shown embodiment differs in that it has a substantially triangular cross-section. In the FIG. 13 Soundproofing device 50 shown also has an openable and closable access opening 66 which is mounted via a hinge 68.

Another alternative embodiment of the soundproofing device 50 is shown in FIG FIG. 14 shown. This embodiment has a plurality of soundproofing elements 86 which can be pushed into one another in the driving direction 16. In the uncoupled state of the soundproofing elements 86, these envelop the gripping device 24, the bearing device 26 and thus the holding device 28 as a whole, as well as the feed device 60 formed by the gripping device 24 is enclosed and also the hammer device 12 is surrounded by the sound insulation elements 86 pushed together.

If the soundproofing elements 86 are pushed together, then the feed device 60, the gripping device 24 or the holding device 28 as a whole as well as the hammer device 12 are accessible from the radial direction. The soundproofing elements 86 are telescopable in that they each have an upper portion 88 which is wider than a respective lower portion 90, so that the soundproofing elements 86, which are hollow inside, can be pushed into one another in a simple manner.

The pushing together of the soundproofing elements 86 can be carried out in a simple manner, for example via a tensioning system 92, that a tensioning element 94, which is designed here as a rope, which is attached to the lowermost soundproofing element 86 and is connected via a deflection roller 96 with a winch 98. Via the winch 98, the lowermost soundproofing element 86 can be pulled upwards, as a result of which all the soundproofing elements 86 located above are likewise pulled upwards so that all soundproofing elements 86 can be pushed into one another.

In FIG. 15 a pile shoe store 100 is shown.

The separating means 48 designed as a rotatable cutting disc is mounted by means of a pivotable arm 108 and can be moved about the driven pile 18 by means of a traversing mechanism 110. If the cutting disk 48 is moved along a first direction 112, the pivotable arm 108 folds up against the driven pile 18 and, via a rotation of the cutting disk 48, the driven pile 18 is severed. When the blade 48 is moved along a second direction 114, the pivotable arm 108 folds the blade 48 away from the driven pile 18. This position is shown by a dashed line.

As a result, the cutting disc 48 can be moved back to its original position without being in contact with the driven pile 18. In FIG. 17 is the storage device 26 in Detail shown. The bearing device 26 has a membrane unit 116. The membrane unit 116 can be filled with air, whereby it expands inwards in the radial direction, which is indicated by arrows with the reference numeral 118.

When the membrane unit 116 is moved inwardly, four rollers 120 mounted on the membrane unit also move radially inward. The rollers 120 serve for contacting the ramming pile 18 held in the bearing device 26. The rollers 120 permit a movement of the driven pile along the ramming direction orthogonal to the image plane. The rollers 120 are designed to be blockable. The membrane unit can also be widened in the radial direction, which is represented by further arrows with the reference numeral 122. As a result, the driven pile 18, which is held in the bearing device 26, are released.

FIG. 18 shows a section through the bearing device 26 along the line XIII-XIII FIG. 17 , A retracted state of the diaphragm unit 116 in the radial direction is shown by a broken line, while the radially narrowed state of the diaphragm unit 116 is shown by a solid line.

In FIG. 19 a movable support system 124 for the piling device 10 is shown. The mobile support system 124 is designed as a tracked vehicle with Auslegearm 36. Chains 126 are located at the bottom of the support system. The mobile support system 124 is presently a conventional excavator. On the support system 124 depot devices 128 are arranged. In the depot 128 additional ramming piles 130 are added to respective storage positions LP.

Not all of the additional piling piles 130 received in the depot facilities 128 are in FIG. 19 shown and only two of the illustrated additional piles 130 carry a reference numeral.

In the in FIG. 19 Depot devices 128 are shown mounted near the chains 126. However, this is not absolutely necessary, but in the context of the invention, other locations for attaching the depot facilities 128 are possible.

In FIGS. 20 and 21 is a lower part of the support system 124 in a plan view and in FIG. 21 shown in a side view.

FIG. 22 shows how the additional ramming piles 130 from the depot device 128 can be received in the magazine device 52. For this purpose, the magazine device 52 is moved down along the guide device 30 and the boom 36 of the support system 124 is tilted. The self-tapping magazine catcher 56 then engages a forward end or sleeve portion 22 of an additional driven pile 130.

If the boom 36 is then pivoted back, then the self-tapping magazine magazine 56 closes and pulls the additional pile pile 130 from its storage position LP. The magazine gripping device 56 is then moved upwards along the guide device 30, which then transfers the additional driven pile 130 to the ready position BP, so that this additional driven pile 130 is then a further driven pile 54 in the magazine device 52. The erected position of the piling device 10 and the guide device 30 is in FIG. 22 represented by a broken line.

The support system 124 has a position sensor device 132. The position sensor device 132 is designed as a differential GPS device via which the Support system 124 can detect its position on a construction site and transmit to, for example, a central host computer system. Likewise, the support system 124 may receive control signals from a controller through the position sensor device 132. A differential GPS device may also be provided on the guide device itself in order to detect their position accurately.

Alternatively, the support system 124 may also have autonomous self-control, which autonomously departs a blueprint using the differential GPS signals and autonomously introduces ram piles 18 at designated locations.

In FIG. 23 an advantageous development of the piling device 10 according to the invention is shown. In the FIG. 23 shown development comprises a mortar supply 134 with a conveying direction 136th

Mortar can be introduced into a ground pile 40 located in the bottom 40 via the mortar feed device 134. Hereby, the driven pile 18 can be filled with mortar on the one hand, and on the other hand, a mortar casing for the driven pile 18 can be created if it is introduced into the ground 40 with an oversized pile shoe 44. The ascending first section 138 and the second partially extend in the soundproofing device 50, while the flexible second section 140 of the mortar supply device 134 runs completely in the soundproofing device 50. This ensures that no increased noise emissions occur through the use of the mortar feed device 134.

The FIGS. 24 to 26 show a further possibility for the formation of the magazine device 52.

The magazine device 52 comprises two arms 142, each having a rail 144. On the rails 144 self-tapping magazine storage devices 56 are in turn arranged to be movable.

The arms 142 are pivotable via a pivoting device 146 designed as a cable (see FIG. 25 ). As a result, inclined piles can be easily introduced into the ground.

Via the rails 144, the additional piles 54 of the gripping device 24 can be supplied.

The additional posts 54 held by the self-tapping magazine catchers 56 are retained at their upper end in the self-tapping magazine catchers 56 and also at lower ends 148 on lower arms 148.

When pivoting the arms 142 via the pivoting device 146, the lower arms 148 are also pivoted. The additional piles 54 can thus be placed obliquely and obliquely introduced into the ground.

The soundproofing device 50 can, as in FIG. 27 shown to be box-shaped. The soundproofing device 50 can also comprise at least one door 150, preferably a plurality of doors 150, via which additional piles 54 can be supplied to the gripping device 24.
