Definitions

  • the invention relates to driving a series of sheet pile planks which are displaceably couple to one another into the ground.
  • the series of sheet pile planks is first assembled, in which case they engage with one another along their longitudinal edges so as to be displaceable.
  • the bottom edge of the series which is thus assembled is then placed on the ground.
  • a drive-in apparatus engages with the upper edge of the series and can drive the various sheet pile planks individually into the ground and/or keep them stationary.
  • Such a drive-in apparatus is known per se, and will therefore not be described in more detail. It has grippers, each of which can grip a sheet pile plank, and drive means for displacing the grippers with respect to one another.
  • Driving into the ground can be carried out by, for example, static pressing by means of hydraulic piston/cylinder devices, vibrating and the like.
  • the speed at which sheet pile planks can be driven into the ground depends inter alia on the soil conditions.
  • an injection member may, for example, consist of a pipe which extends along the bottom edge of the sheet pile plank, which pipe has holes from which the medium flows out.
  • the medium results in a softening of the soil material, but at the same time the flow has to be sufficiently powerful to prevent soil material from entering the holes. This is important in order to prevent the holes from becoming blocked and thus prevent the injection member from becoming inoperative.
  • JP-A-6-101229 A method for driving a series o sheet pile planks which are displaceably coupled to one another in the longitudinal direction into the ground is disclosed in JP-A-6-101229 , which is regarded as closest prior art.
  • Said prior art method comprises the steps of:
  • a continuous flow of the medium from the injection member is maintained, even during those stages in which the sheet pile plank is kept stationary.
  • This has the advantageous effect that even during these stationary stages, material from the ground is prevented from collecting in the holes of the injection member as a result of the groundwater pressure.
  • a flow at a slight excess pressure is maintained from said holes which may, however, be significantly smaller than the flow which is required to drive the sheet pile plank into the ground.
  • the injection member may be of a simple design, since no valves are necessary to prevent material from the ground from entering.
  • the holes in the injection member may be permanently open without this causing a blockage which could result in obstruction during the stage when the sheet pile plank is driven into the ground, which follows a stationary stage.
  • the method according to the invention may comprise the following steps:
  • the invention furthermore relates to a device for carrying out the method according to one of the preceding claims, comprising individual drive-in means for acting on a sheet pile plank, pressure means for supplying fluid to the individual sheet pile planks at excess pressure, which pressure means are designed for dispensing fluid either at a relatively high pressure and/or at a relatively high flow rate, on the one hand, or dispensing fluid at a relatively low pressure and/or a relatively low flow rate, on the other hand, as well as control means for activating the drive-in means associated with a first sheet pile plank.
  • Such a device is disclosed in JP-A-6101229 as well.
  • the object of the invention is to improve said prior art device. Said object is achieved in that the individual drive means are for individually acting on at least two sheet pile planks and in that the control means are carried out for the pressure means to be simultaneously supplying the fluid at a relatively high pressure and/or a relatively high flow rate to said first sheet pile plank and simultaneously supplying the fluid at a relatively low pressure and/or a relatively low flow rate to a second sheet pile plank which is kept stationary.
  • EP-A-1717375 discloses a device for sheet pile planks.
  • Said device comprises individual drive-in means having several independent drives for acting simultaneously on a corresponding number of individual sheet pile planks.
  • said device lacks pressure means for supplying a fluid to the sheet pile planks.
  • Fig. 1 shows a series 1 comprising four sheet pile planks 4. These sheet pile planks 4 are connected in pairs by lock connections 17 known per se which will not be described in more detail.
  • the bottom edge 5 of the sheet pile planks 4 is arranged on the ground 2 into which the series 1 has to be driven.
  • the device for driving the series 4 into the ground is denoted overall by reference numeral 3.
  • This device 3 has a housing 6 in which four individual drive-in devices 8 are accommodated. Each individual drive-in device 8 has a gripper 10 which acts on the upper edge 6 of an individual sheet pile plank 4.
  • the device 3 is suspended from a stand, which is known per se (not shown) for treating the series of sheet pile planks.
  • a distributor 12 is also arranged which is provided with valves and to which a pressure pipe 11 is connected. Furthermore, liquid lines 13 are connected to the distributor 12, each of which leads to one of the sheet pile planks 4. Over the length of each sheet pile plank, a supply line 14 extends to which the associated liquid lines 13 are connected. On the underside of each supply line 14, the transverse line 15 illustrated in Fig. 5 is connected which has a series of holes 16 along its length.
  • a liquid for example water
  • a pump not shown
  • the valves in the distributor 12 are all closed.
  • one of the individual drive-in devices 8 is activated.
  • the liquid is supplied to the supply line 14 via the distributor 12 and the associated liquid lines 13 and is thus supplied to the transverse line 15.
  • water 19 is thus injected into the ground under excess pressure, in such a manner that as a result of the softening of the ground in combination with the driving forces exerted by the drive-in device 8 on the respective sheet pile plank 4, the respective sheet pile plank is driven into the ground for a certain distance.
  • Fig. 2 shows this first stage of introducing the series of sheet pile planks into the ground, with the sheet pile plank on the right-hand side having already been driven into the ground slightly.
  • this drive-in device 8 When the associated right-hand individual drive-in device 8 has performed the maximum travel at which driving of the associated sheet pile plank 4 takes place, this drive-in device 8 is brought to a stationary position, with the respective sheet pile plank 4 also being brought into a stationary position.
  • the next sheet pile plank 4 is then driven into the ground along a certain length by means of the adjacent drive-in device 8.
  • the distributor 12 delivers water which is now under excess pressure to said respective sheet pile plank, as a result of which water 19 is injected into the ground under excess pressure.
  • the distributor 12 also delivers a certain amount of water to the transverse line 15 of this first sheet pile plank 4, which is in a stationary position because the associated drive-in device 8 is switched off.
  • the advantage of supplying an amount of water to the stationary sheet pile plank is that the holes 16 in the transverse line 15 thereof do not become blocked in the stationary position. The fact is that an excess pressure may build up in the ground as a result of the injection of water, so that water mixed with soil material could end up in the holes 16 and thus in the transverse line 15 if there were no counterpressure.
  • the above-described process is repeated by then driving the third sheet pile plank 4 into the ground using a water flow 19 having a relatively high pressure and/or a relatively high flow rate, and by simultaneously causing a certain water flow 18 (having a relatively low pressure and/or low flow rate) to flow from the holes 16 of the transverse line 15 of the preceding two sheet pile planks 4.
  • a certain water flow 18 having a relatively low pressure and/or low flow rate
  • the first sheet pile plank is again driven further into the ground, with liquid at a higher pressure and/or at a higher flow rate being supplied to said sheet pile plank, so that, in combination with the action of the associated drive-in device 8, said sheet pile plank 4 can be driven into the ground by a certain distance.
  • the supply of water at a certain excess pressure to the other three sheet pile planks is maintained, so that no blockage can occur in the transverse line 15 thereof.
