Definitions

  • the invention relates to a method for driving in ramming parts under water, in which a ramming device hanging on a support element and a submersible, electro-hydraulic drive unit are lowered under water and a ramming part is driven in by the ramming device driven by the submerged drive unit, and a method suitable for carrying out this method Drive unit.
  • the ram piles used for this must often be dimensioned stronger and heavier than for the actual anchoring of the structure is necessary so that the ram pile, which is particularly long in the first phase of ramming and is therefore sensitive to bending forces, does not suffer bending damage from the heavy weight of the pile driver weighing several hundred tons and its high impact energy, or from the intended one Driving direction differs.
  • Such thick-walled tubular steel piles which in practice are often over a hundred meters long, are not only very expensive, but also difficult and dangerous to handle, especially since workshop ships with correspondingly large and strong jib cranes are required.
  • the ram pile which initially protrudes long from the sea floor, can only be pre-rammed with a light piling device with relatively low impact energy until no more difficulties with its flexibility are to be expected. Then the light pile driver has to be caught up and a heavier pile driver has to be lowered onto the pile in order to drive it into the intended penetration depth. To do this, however two different pile drivers are lowered one after the other onto the pile and brought up again over water, which takes a lot of time under the not always favorable weather conditions for offshore work and therefore a correspondingly high effort because of the enormous costs of modern workshop ships.
  • the object of the invention is now to provide a method for driving in rammed parts under water of the type mentioned at the outset and a drive unit suitable for this purpose, which in a simple manner enables time and labor-saving, more economical driving in of rammed parts.
  • the thin, thin-walled and lighter driven piles corresponding to the actual foundation requirements can be rammed in much more quickly and efficiently without risk of damage, using two preferably different heavy rammers.
  • the advantages are particularly pronounced when a plurality of adjacent driven piles are to be driven in. Since both pile drivers can be driven with one and the same drive unit in accordance with their energy requirements, only one drive unit is required flexible implementation of pile driving.
  • the invention furthermore, based on the preamble of claim 16, relates to a submersible, electrohydraulic drive unit for underwater piling equipment which is suitable for carrying out the method and has the features of claim 16.
  • This drive unit can also be designed in the manner described in the parallel European patent application EP-A-030 1116 from the same filing date.
  • the conventional method of driving free-standing ramming piles under water works with a ramming hammer 1 hanging from a crane rope 4 from the crane K of a work ship 5, which has several with a drive unit 2 with a pressure medium container 13 attached to its top with this connected via hose lines 12, each driven by electric motors pump units 11 with the interposition of shock absorbers.
  • the pump units 11 are connected to the hydraulic cylinder (not shown) of the ramming hammer 1 by hose lines 9 and 10.
  • the drive unit is supplied with electrical energy via a umbilical 8 guided by a winch 6 of the work ship 5 via a deflection roller 7.
  • the umbilical 8 contains a sufficient number of electrical lines and, in the usual way, the control lines, air supply lines, etc. required for actuating and controlling the ramming hammer 1 and the drive device 2. Since the parts of the drive device are arranged one above the other in the longitudinal direction, the one in the Practice at least about 20 m long hammer 1 and the overall arrangement consisting of at least about 30 m of the drive unit is of considerable length, so that it is particularly difficult to handle, particularly when picking up and putting down on the deck of the work ship 5. In addition, the elongated overall arrangement when lowering under water is difficult to position over the head of the ram pile in such a way that the ramming hammer 1 can be properly placed on the ram pile 14.
  • the heavier pile driver 1 hanging on the suspension cable 4 of the crane K of the work ship 5 is lowered with a lighter pile driver 15 attached to it via a further support element 3 and enclosed by a drive unit 2 connected to it which in turn is supplied with energy via an umbilical 8 and, on the other hand, is not only connected to the associated piling device 15, but also to the heavier piling device 1 via hose lines 9 and 10 and signal lines (not shown).
  • the pump units of the drive unit 2 can each be driven individually or in groups, and the pressure medium flow supplied by them can be supplied to the two rammers 1 and 15 via a switching device with adjustable volume fractions, these can also be driven independently of one another.
  • the lighter ramming device 15 connected to the drive unit 2 is placed on a ramming pile 14 installed ready to drive on the seabed, but still projecting freely with most of its length.
  • the lighter pile driver 15 is now driven by the drive unit 2 to first drive the pile driver 14 with a relatively low weight load and limited impact energy to such an extent that the heavier pile driver 1 can then be placed on the pile driver 14 without endangering it.
  • FIG. 5 This state is shown in which the lighter pile driver 15 moves from the already sufficiently driven pile 14 to an adjacent one Driving pile 14 implemented and the heavier pile driver 1 was applied to the pre-driven pile.
  • the lighter pile driver 15 is then simultaneously driven to advance its pile, while at the same time the heavier pile driver 1 driven by the drive unit 2 via the hose lines 9 and 10 rams the previously driven pile 14 to the intended penetration depth.
  • FIG. 6 shows an advanced phase of a similar mode of operation, but in which the drive unit 2 is connected to the heavier pile driver 1.
  • This arrangement has the advantage that the smaller piling device 15 freed from the drive unit 2, when placed on the ramming pile 14, causes the weight of the latter to be significantly lower, so that it can be pre-rammed particularly gently.
  • both pile drivers 1 and 15 are seated next to each other on adjacent pile piles 14 in the manner shown in FIGS. 5 and 6, it is of course also possible first to drive the pile pile 14 which has already been rammed in with the heavier pile driver 1 with the full energy of the drive unit 2 to the intended penetration depth , whereupon the next pile driver 14 is pre-rammed with the smaller pile driver 15.
  • this requires longer hose lines between the drive unit 2 and the ramming device 1 or 15, which is separate from the latter, since these move farther from one another than when working with the reverse driving sequence. The longer hose lines also make handling more difficult and cause additional costs.
  • two ramming devices 1 and 15 of different weights and different impact energy can be driven in with one and the same drive unit 2 and the ramming piles one after the other in a time-saving and efficient manner with only one lowering of the devices. Since that is in the meantime the necessary catching up of the devices over water and the associated handling risk is eliminated, overall considerable time, labor and cost savings are achieved.
  • the pile drivers 1 and 15 can be lowered on separate support ropes 4 and 3 so that the drive unit 2 attached to a pile driver 15 can both be driven with this , as well as via hose lines 9 and 10 and signal lines as well as a shorter distance limiting rope 47 is connected to the other pile driver 1.
  • the lighter pile driver 15 is designed as a vibration pile driver with unbalance motors driven by the hydraulic pumps of the drive unit 2 via hydraulic motors. According to a modified method of operation, indicated by dash-dotted lines in FIG.
  • one of the pile drivers preferably the lighter vibration pile driver 15, can also be suspended directly from the umbilical 8, which is required anyway for supplying the drive unit 2, and which is driven by a winch 6 on the work ship via a deflection roller 7 hangs on the crane k.
  • the Umbilical 8 which is designed for rough handling during offshore work, is usually designed to be particularly robust anyway and also withstands a relatively large tensile load.
  • This arrangement also makes it possible to keep the very expensive Umbilical 8 shorter, since it does not first have to be guided from the winch 6 to a deflection roller 7 at the upper end of the crane boom, which has a significant impact on work cranes with boom lengths over 100 m.
  • the lighter piling device 15 first rams one or more ramming piles 14 and / or the heavier piling device 1 simultaneously drives in another, possibly more resilient piling pile 14 and then is to be converted to pre-rammed piles 14 or both ramming piles 1 and 15 should drive in ram piles 14 which are assigned side by side.
  • it can also make sense to have two To drive rammers with the same impact power or weight next to each other by the same drive unit 2.
  • the progress of the individual ramming processes can also be observed side by side and, if necessary, the volume distribution of the pressure medium flow conveyed by the drive unit into the partial flows supplied to the individual ramming devices 1 and 15 can be adapted appropriately.
  • the left pile driver 14 has already been rammed a sufficient distance with the lighter pile driver 15, while the heavier pile driver 1 is either held above the right pile driver 14 or is deposited on it in the manner shown in broken lines. He can either remain stationary there or, if the drive unit has sufficient drive capacity and the delivery quantity divided as required, can work simultaneously with the lighter piling device 15.
  • the lighter ramming device 15 designed as a ramming hammer with the attached drive unit 2 is placed on a ramming pile 14 provided with a striking plate 28.
  • the drive unit 2 has a jacket housing with a continuous central receiving shaft A, an annular upper supporting plate 17, an annular lower supporting plate 18 provided with an insertion cone 19, an outer jacket wall 16 connecting the supporting plates and a cylindrical inner wall 20 surrounding the receiving slot A.
  • the annular space lying between the cylindrical jacket wall 16 and the inner wall 20 is a plurality of around its circumference
  • Distributed pump units 11 are arranged, each comprising an electric motor 21 and a hydraulic pump 24 connected to it and are aligned parallel to the longitudinal axis of the receiving shaft A.
  • Each pump unit is assigned an essentially cylindrical pressure medium container 22, which is connected to the hydraulic pump 24 via a hose line 46.
  • the electric motors 21 are connected to corresponding electrical lines in the umbilical 8 via separate electrical lines 43 and a watertight junction box arranged on the upper support plate 17.
  • the pump units 11 are each attached to the inner wall 20 via elastic support elements (not shown), which in turn is elastically cushioned relative to the lower support plate 18 and the upper support plate 17 by a plurality of prestressed spring cylinders 29 with pistons 30 distributed over the circumference and advantageously additionally by corresponding spring cylinders can also be supported radially inwards against the pile 14 or the hammer housing of the pile driver 15.
  • the pressure medium conveyed by the hydraulic pumps 24 flows via a hose line 44 to a switching device 37 arranged on the upper support plate 17, connected to the umbilical 8 via a signal line 42 and via a downstream collecting connection 31 and a hose line 33 to the hydraulic cylinder of the ramming device 15 and, if appropriate Via a hose line 9 to the ramming device 1.
  • the returning pressure medium runs via a hose line 34 or 10, the collecting connection 31 and a return line 45 to the pressure medium container 22. Further details in the arrangement, design and suspension of the electric motors 21, the hydraulic pumps 24 and the pressure medium container 22, and the lines connecting them to each other and to the piling device 15 are in the parallel European patent application further explained to the applicant from the same filing date.
  • At least one buoyancy tank 23 is also attached in the annular space between the jacket wall 16 and the inner wall 20, which either has a wall that withstands the intended diving depth or can be filled with gas via a supply line integrated in the umbilical 8 while expelling water.
  • FIG. 11 shows, two buoyancy containers 23 are provided in the embodiment shown, which extend over essentially the entire height of the jacket wall.
  • Each buoyancy tank 23 expediently has a lockable opening on the bottom for the inlet and outlet of water and a lockable top inlet opening for gas, so that both the extent of the gas filling in the buoyancy tank 23 and the gas pressure can be adjusted by appropriate control.
  • the pile driver 15 is detachably connected to the lower support plate 18 of the drive unit 2 via a fastening flange arranged in the lower section of the hammer housing.
  • the lower support plate 18 also carries a cylindrical downwardly projecting pile guide 25, the interior of which is also designed as a buoyancy container 26. This can be filled with gas via a gas supply line 38, a valve 39 and a passage opening 40.
