Definitions

  • the invention relates to a handling device for gripping and inserting a pile tube into a hole in the ground to form a foundation pile, with a base frame, a gripping device for gripping and holding the pile tube and a holding element for releasably connecting the base frame with a hoist, in particular a support cable, according to the preamble of claim 1.
  • the invention further relates to a method for gripping and inserting a pile tube into a hole in the ground, according to the preamble of claim 12.
  • From the EP 2 930 275 A1 disclose a method and an arrangement for producing a foundation pile for a structure in water.
  • a borehole with a support pipe is first created in the ground.
  • the resulting hole is filled with a liquid, especially water.
  • a pile pipe is inserted into the cased borehole created in this way, for which a simple steel pipe with a tubular base body is used.
  • the external support pipe is then pulled out and the annular space between the inserted pile pipe standing on the bottom of the borehole and the surrounding bore wall is filled with a hardenable medium.
  • the surrounding water can remain within the pile tube.
  • the load-bearing capacity of the foundation pile created in this way is determined by the outer surface of the pile tube used in relation to the surrounding soil with the hardened medium in the surrounding annular space. If necessary, the interior space, which is only filled with water, can be used to install measuring or testing equipment.
  • a device for handling and inserting a pile pipe into a bore is known.
  • the device is designed to be attached to a suspension cable of a crane. Using gripping elements, an annular edge of the pile tube can be gripped in a non-positive manner. Overall, the device is designed so that the pile tube can be pivoted from a horizontal storage position into a vertical insertion position.
  • the underwater drilling rig can be placed on a body of water.
  • a foundation hole is created using tubular elements.
  • the tubular elements can also be used to anchor the drilling device under water.
  • the outer annular space between the lateral surface of the pile tube and the surrounding hole wall is filled.
  • a hardenable medium such as mortar or a cement suspension
  • the introduction of the curable medium should, if possible, take place in such a way that the annular space is filled from below, so that liquid in the annular space, in particular water, is displaced by the curable medium from bottom to top.
  • the hose is usually inserted into the annular space manually from outside the bore.
  • the problem is that a supply hose can get caught in a central area of the drilling and therefore does not reach the bottom of the drilling hole. This is usually not detectable from outside the bore.
  • the curable suspension is supplied with such an incorrectly inserted supply hose, liquid can remain in the annular space below the supply hose and be enclosed by the curable suspension above it. In such a case, a pile tube would not be connected to the surrounding soil over its entire length after the suspension has hardened. This reduces the load-bearing capacity of a correspondingly formed foundation element, so that a reliable foundation is no longer guaranteed.
  • the invention is based on the object of specifying a handling device and a method with which a pile tube can be efficiently inserted into a hole in the ground to form a foundation element.
  • the handling device is characterized in that at least one inlet device for supplying a curable medium is arranged on the base frame in an upper region and at least one outlet device for the curable medium to the pile tube is arranged in a lower region.
  • a basic idea of the invention is to use the handling device not only to grip and insert the pile tube into the bore, but also to introduce the hardenable medium into the bore.
  • the handling device is not detached from the pile tube, in particular after the pile tube has been inserted into the bore, but can remain in a defined initial position on the pile tube, which was assumed outside the bore when the pile tube was gripped by the handling device. Through the so specified Relative position between the pile pipe and the handling device, a reliable supply of the curable medium can take place via the handling device.
  • the handling device on the base frame has at least one inlet device for supplying a curable medium in an upper region and at least one outlet device for the curable medium to the pile pipe in a lower region.
  • the outlet device can be connected to a corresponding feed device on the pile pipe.
  • a preferred embodiment of the invention is that the gripping device has a plurality of gripping elements for positively and/or non-positively holding the pile tube.
  • the gripping device serves to releasably connect the handling device to the pile tube.
  • the connection can be made in any suitable way, in particular solely by or in conjunction with a non-positive tensioning of the pile tube.
  • clamping or clamping devices in particular collet chucks, can be provided.
  • the gripping device is designed for positively and/or non-positively holding the pile tube on its inside.
  • the gripping device can therefore grip and hold the pile tube solely on its inside, in particular tension it in a non-positive manner.
  • the handling device can be designed so that it is located within the outer circumference of the pile tube and does not protrude beyond an outer diameter of the pile tube.
  • the handling device can therefore be arranged entirely or partially within the pile tube.
  • the pile tube can thus be inserted into a bore with an only slightly larger bore diameter and thus a correspondingly small annular space between the outer circumference of the pile tube and the surrounding bore wall. In this way, consumption of hardenable medium, in particular mortar or a cement suspension, can be kept as low as possible.
  • a particularly reliable holding of the pile tube can be achieved in that the gripping device has at least one actuating cylinder, with which at least one gripping element between a Holding position for holding the pile tube and a release position is adjustable, in which the at least one gripping element is released from the pile tube.
  • the actuating cylinder can in particular be designed as a hydraulic cylinder or a pneumatic cylinder.
  • the actuating movement of the actuating cylinder which is preferably arranged in the longitudinal direction of the handling device and the pile tube, can be transmitted to one or more gripping or holding elements via a lever mechanism.
  • the inlet device has a connecting device for connecting a supply line.
  • the supply line can be a so-called umbilical, which can be designed to supply the curable medium, energy, in particular electrical, hydraulic and/or pneumatic energy, other fluids, such as a rinsing liquid and/or air, and/or data.
  • the connecting device can in particular be designed in the form of a plug connection or in another suitable manner.
  • the connecting device can also be particularly advantageous for the connecting device to include a quick-release device in order to ensure quick release in certain emergency or dangerous situations, such as heavy seas, in order to avoid an uncontrolled tearing of the supply line.
  • the outlet device has at least one outlet for connecting to a feed opening on a pile pipe.
  • One or more delivery lines can extend along the handling device between the inlet device and the outlet device.
  • the outlet device can also be designed in such a way that it can engage with a corresponding feed device on the pile pipe in order to ensure a reliable transfer of the curable medium from the outlet device to the feed opening on the pile pipe.
  • One or more inlet funnels can preferably be arranged on the feed device on the pile pipe, into which one or more outlet pipes of the outlet device protrude and/or can be inserted.
  • the funnels can also be referred to as inlet funnels, which make it easier to insert and thus connect the outlet device and the feed opening.
  • an attachment element for placing the handling device on the pile tube is arranged in the bore.
  • the handling device is connected to the pile tube, in particular before the pile tube is inserted into the bore. This allows a reliable and controlled connection between the handling device and the pile pipe.
  • the placement or arrangement can take place at an upper edge of the pile tube and/or also in an interior area of the pile tube at a suitable position.
  • a particularly efficient operation of the handling device can be achieved by arranging at least one adjusting device with which the attachment element with the pile tube can be adjusted and adjusted relative to a surrounding wall of the bore, a support tube and/or a base frame of the handling device.
  • the handling device can therefore also be used for a certain subsequent adjustment of the pile pipe relative to the surrounding bore wall. This allows the quality of the foundation element to be formed to be further increased.
  • the adjusting device can in principle be designed with a suitable adjusting device for adjustment and adjustment. According to one embodiment of the invention, it is particularly advantageous that the adjusting device has at least one actuating cylinder, in particular a hydraulic cylinder.
  • the handling device can in particular be attached to a hoist, in particular a support cable or a support rod on a crane. It is advantageous that the holding element has an eyelet or a hook. In this way, a detachable connection can be produced in a particularly simple and reliable manner, in particular with a crane hook or another common connecting element on a support cable or a support rod.
  • the inlet device and the outlet device extends two delivery lines, which can be switched by means of a valve device in such a way that they can be connected in parallel to form a double supply line or connected in series for a flushing operation.
  • the curable medium can be supplied via the at least two delivery lines in the same direction.
  • the valve device By actuating the valve device, the two delivery lines can be connected in series, so that a first delivery line can serve as a supply line for a rinsing liquid and the series-connected second delivery line can serve as a return line for the rinsing liquid.
  • the two delivery lines can be reliably flushed free of the curable medium so that they do not become clogged and can therefore be used multiple times.
  • the invention further relates to a method for gripping and inserting a pile tube into a hole in the ground, using a previously described handling device according to the invention. With this method, the advantages described above can be achieved when using a handling device.
  • a hardenable medium is supplied to the pile pipe via the handling device while the pile pipe is held by the handling device.
  • hardenable medium can be supplied to the pile tube from the outside in a particularly reliable manner and, in particular, can be introduced into a surrounding annular space around the pile tube. In this way, a high quality foundation element can be produced without excessive consumption of curable medium.
  • the handling device is arranged with an attachment element on the pile tube and that the base frame with the gripping device and the pile tube held therewith is adjusted and adjusted relative to a support tube or the bore with at least one adjusting device. This allows an exact alignment of the pile tube within the bore with the handling device.
  • a further advantageous method variant according to the invention is that the handling device is attached to the pile pipe after it has been inserted into the bore is released from the hoist and/or a supply line and can remain as a load on the pile pipe.
  • the handling device is further attached to the pile tube and can thus remain as an additional ballast for fixing the pile tube thereon, at least until the curable medium introduced into the annular space around the pile tube has sufficiently hardened and solidified.
  • the handling device can then be detached from the pile pipe and recovered using the hoist.
  • a pile tube 10 with a tubular base body 12 is provided.
  • a bulkhead plate 20 directed transversely to the longitudinal axis of the tubular base body 12, which divides the interior region 13 into a lower section 14 and an upper section 15 and separates them from each other.
  • An annular sealing element 19 can be arranged on a lower edge of the tubular base body 12, with which the pile tube 10 can be placed on a borehole base in as sealing as possible.
  • the bulkhead plate 20 has two schematically indicated through openings 22, which can be opened or closed in a targeted manner by means of a closure device 24, which is also schematically indicated.
  • a feed device 30 with two schematically indicated feed openings 32, each with an insertion funnel 34, as will be described in more detail below in connection with Fig. 3 is described.
  • the feed openings 32 with the insertion funnels 34 serve to supply a hardenable medium, in particular mortar or cement suspension, whereby the hardenable medium can be guided below the bulkhead 20 via lines 26 to a lower end region of the tubular base body 12.
  • the lines 26 extend through a tube wall 16 of the base body 12 and each open into an outlet opening 28 on the outer circumference 17 of the base body 12. Curable medium can thus be passed over an inner area 13 of the pile tube 10 to a lower end area and via the outlet openings 28 exit outside the pile tube 10, as described in more detail below in connection with Fig. 2 is explained.
  • FIG. 2 A lower end region of a pile tube 10 according to the invention is shown schematically and not to scale, which is inserted into a hole 4 in the ground 1. Only the lower area of the hole 4 is shown, whereby the hole 4 can have a depth of several meters, typically between 5m and 30m.
  • the bore 4 is filled with a liquid, in particular water or another supporting liquid, for support, so that the bore 4 does not collapse even at greater bore depths.
  • a support tube can also be provided at least in some areas.
  • the pile tube 10 with a bulkhead plate 20 can be easily inserted into a bore 4 filled with liquid in this way if the through openings 22 on the bulkhead plate 20 are opened by the closure devices 24.
  • the through openings 22 can be closed again with the closure devices 24.
  • Hardenable medium can now be introduced into the bore 4 via the lines 26, the hardenable medium being supplied within the pile tube 10 in the lower area with the lines 26 and passing through the tube wall 16 at the lower end area and into an annular space 6 via the outlet opening 28 can exit.
  • the annular space 6 is between an outer circumference 17 of the tubular Base body 12 and a substantially cylindrical wall 8 of the bore 4 are formed.
  • the curable medium can fill the annular space 6 from bottom to top due to its higher density compared to the liquid in the bore 4. Liquid is displaced upwards from the annular space 6 by the curable medium.
  • the intended bulkhead plate 20 seals a lower section 14 of the interior area 13 of the pile tube 10 at the top with the through openings 22 closed.
  • the liquid in the lower section 14 of the pile tube 10 cannot be displaced upwards, so that no or hardly hardenable medium can penetrate into the inner region 13 of the pile tube 10.
