Abstract
Description
- The invention relates to driving a series of sheet pile planks which are displaceably couple to one another into the ground. To this end, 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. In this connection, it has already been proposed to fit an injection member to the bottom edge of the sheet pile plank. When the sheet pile plank is driven into the ground, the ground around its bottom edge is locally and temporarily softened by an injected medium, in such a manner that driving into the ground proceeds more easily and quickly. The known 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.
- 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 - keeping at least one of the sheet pile planks stationary,
- driving at least one other sheet pile plank into the ground in such a manner that the other sheet pile plank which is driven into the ground is displaced with respect to the stationary sheet pile plank,
- subsequently keeping the sheet pile plank which has been driven into the ground stationary,
- subsequently driving a sheet pile plank which was initially kept stationary into the ground in such a manner that said sheet pile plank is displaced with respect to the stationary sheet pile plank which was driven into the ground,
- supplying simultaneously a fluid to the bottom ofboth sheet pile planks.
- Also when the sheet pile planks are driven into the ground in a series, as discussed above, it may be desirable to treat the ground by injecting a medium. In this case, however, driving the individual sheet pile planks in is carried out intermittently. This means that a certain sheet pile plank is initially driven into the ground over a distance which is significantly shorter than its own length. However, after it has been driven into the ground over a certain distance, the respective sheet pile plank is kept stationary. If an injection member were present at the bottom edge of the sheet pile plank, this could lead to problems since soil material can enter the holes and block them in this stationary position. For this reason, it has not been readily possible to assist in driving a series of sheet pile planks into the ground by injecting a medium into the ground.
- However, it is an object of the invention to provide a method of the type mentioned in the preamble which does make use of the advantageous effect offered by injection of a medium into the ground. This is achieved by means of a method for driving a series of sheet pile planks which are displaceably coupled to one another in the longitudinal direction into the ground, comprising the following steps:
- the fluid is supplied at a relatively high pressure and/or a relatively high flow rate to the sheet pile plank which driven into the ground,
- the fluid is supplied at a relatively low pressure and/or a relatively low flow rate to the sheet pile plank which is kept stationary.
- When a sheet pile plank is driven into the ground using the method according to the invention, 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. Also, 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.
- This means that the method according to the invention can in particular comprise the following steps:
- using sheet pile planks comprising a permanently open nozzle at the bottom,
- while keeping the sheet pile plank stationary, supplying the fluid at a relatively low pressure with respect to the pressure during fluidization and/or at a relatively low flow rate with respect to the flow rate during fluidization in such a manner that blockage of the nozzle is prevented.
- Furthermore, the method according to the invention may comprise the following steps:
- causing at least two individual drive-in devices to act on the series of sheet pile planks,
- repeatedly and alternately driving each sheet pile plank into the ground and keeping it stationary until the nominal depth position of the sheet pile plank has been reached.
- 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 - Reference is made to
EP-A-1717375 , which 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. However, said device lacks pressure means for supplying a fluid to the sheet pile planks. - Reference is made to the prior art as known from
NL-A-1,004,237 - The invention will now be described further with reference to an exemplary embodiment illustrated in the figures, in which:
-
Figs. 1-4 show different stages of driving a series of sheet pile planks into the ground. -
Fig. 5 shows a perspective bottom view of two sheet pile planks in the series according toFigs. 1-4 . -
Fig. 1 shows aseries 1 comprising foursheet pile planks 4. Thesesheet pile planks 4 are connected in pairs bylock connections 17 known per se which will not be described in more detail. Thebottom edge 5 of thesheet pile planks 4 is arranged on theground 2 into which theseries 1 has to be driven. On theupper edge 6 of thesheet pile planks 4, the device for driving theseries 4 into the ground is denoted overall byreference numeral 3. Thisdevice 3 has ahousing 6 in which four individual drive-indevices 8 are accommodated. Each individual drive-indevice 8 has agripper 10 which acts on theupper edge 6 of an individualsheet 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. - On the
housing 7 of thedevice 3, adistributor 12 is also arranged which is provided with valves and to which apressure pipe 11 is connected. Furthermore,liquid lines 13 are connected to thedistributor 12, each of which leads to one of thesheet pile planks 4. Over the length of each sheet pile plank, asupply line 14 extends to which the associatedliquid lines 13 are connected. On the underside of eachsupply line 14, thetransverse line 15 illustrated inFig. 5 is connected which has a series ofholes 16 along its length. - In use, a liquid, for example water, is supplied to the
pressure pipe 11 at an excess pressure by a pump (not shown). Initially, the valves in thedistributor 12 are all closed. From the starting position shown inFig. 1 , one of the individual drive-indevices 8 is activated. At the same time, the liquid is supplied to thesupply line 14 via thedistributor 12 and the associatedliquid lines 13 and is thus supplied to thetransverse line 15. From theholes 16 in thetransverse 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-indevice 8 on the respectivesheet 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. - When the associated right-hand individual drive-in
device 8 has performed the maximum travel at which driving of the associatedsheet pile plank 4 takes place, this drive-indevice 8 is brought to a stationary position, with the respectivesheet pile plank 4 also being brought into a stationary position. In the next step, illustrated inFig. 3 , the nextsheet pile plank 4 is then driven into the ground along a certain length by means of the adjacent drive-indevice 8. In this case, thedistributor 12 delivers water which is now under excess pressure to said respective sheet pile plank, as a result of whichwater 19 is injected into the ground under excess pressure. Thus, as a result of the combined effect of the respective drive-indevice 8 and the effect which occurs in the ground as a result of thewater 19, this sheet pile plank can be driven into the ground over a certain length. - While this second
sheet pile plank 4 is being driven into the ground, the firstsheet pile plank 4 is stationary, as has already been said before. However, according to the invention, thedistributor 12 also delivers a certain amount of water to thetransverse line 15 of this firstsheet pile plank 4, which is in a stationary position because the associated drive-indevice 8 is switched off. This means thatwater 18 is also injected into the ground from theholes 16 of this transverse line, albeit at a lower pressure and/or with a lower flow rate than thewater flow 19 which is used with the next sheet pile plank which is in the stage of being driven into the ground. The advantage of supplying an amount of water to the stationary sheet pile plank is that theholes 16 in thetransverse 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 theholes 16 and thus in thetransverse 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 awater 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 theholes 16 of thetransverse line 15 of the preceding twosheet pile planks 4. Eventually, theentire series 1 ofsheet pile planks 4 can thus be driven into the ground by a certain distance. Subsequently, 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-indevice 8, saidsheet pile plank 4 can be driven into the ground by a certain distance. In this case, 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 thetransverse line 15 thereof. After a number ofsuch cycles 1, the entire series has been driven into the ground. -
