Abstract
Description
- The invention rel ates to a method for driving a pile into the ground to a position below the ground level by means of a lengthening piece which is pulled out of the ground after the pile has been driven to the desired depth, wherein said pile is provided with at least one pipe which is open at its ends, said pipe extending at least substantially along the length of the pile and being fixed to said pile.
- Such a pipe fixed to the pile is used for supplying grout into the ground near the lower end of the pile while the pile is being driven into the ground, in such a manner that the pile is being provided with a grout envelope.
- When the pile is inserted into the ground in such a manner that the upper end of the pile is positioned near the ground level, such supplying of grout can generally take place without any problems. A problem arises, however, when the upper end of the pile is to be driven into the ground to a position some distance below the ground level by means of a so-called lengthening piece that is to be placed on the upper end of the pile.
- According to the invention, a lower end of a flexible pipe accommodated within the extension piece is connected to the upper end of the pipe that is fixed to the pile, and an upper end of the flexible pipe that freely extends within the lengthening piece is connected to a grout pump via a lead-through extending through the wall of the lengthening piece, with grout being forced into the ground through the open lower end of the pipe that is fixed to the pile, via the flexible pipe and the pipe fixed to the pile, by means of the grout pump during the pile-driving operation, and once the pile has been inserted into the ground to the desired depth, the lengthening piece together with the flexible pipe accommodated in the lengthening piece is pulled out of the ground, with the flexible pipe being pulled loose from the pipe that is fixed to the pile.
- The use of a flexible pipe in the lengthening piece, which is only connected to a lead-through extending through the wall of the lengthening piece with one end and which is connected to the pipe that is fixed to the pile with its other end prevents the flexible pipe being exposed to load variations during the pile-driving operation, which load variations may cause the connection between the pipe and the lengthening piece and even the pipe itself to fracture in those cases in which a rigid pipe fixed to the lengthening piece is used.
- In accordance with the invention, a suitable lengthening piece for implementing the method according to the invention is provided with a flexible pipe extending freely within the lengthening piece, which pipe is connected with one end to a lead-through extending through the wall of the lengthening piece.
- The invention will be explained in more detail hereinafter with reference to the accompanying schematic Figures.
- Figure 1 schematically shows the insertion of a pile into the ground by means of a lengthening piece placed on the upper end of the pile.
- Figure 2 is a sectional view of Figure 1 along the line I-I in Figure 2, showing the pile in a position turned through 90° relative to the position that is shown in Figure 1.
- Figure 1 schematically shows a
pile 1, which has been inserted into the ground to a position some distance below the ground level 3 by means of alengthening piece 2. As is shown in particular in Figure 2, apile 1 of H-shaped section is used in the illustrated embodiment, but it will be understood that the method according to the invention can be carried out in the same manner with piles having a different sectional shape. - Two rigid pipes or
tubes 4 having open ends are fixed to thepile 1, which pipes are intended for passing grout therethrough. Furthermore, aweighted foot 5 is connected to the lower end of thepile 1 in the illustrated embodiment. - As already said before, a
lengthening piece 2 placed on top of thepile 1 is used for driving thepile 1 into the ground to a position below the ground level, on the upper end of which lengthening piece apiling hammer 6 may act for driving the pile into the ground. - A
hammering plate 7, which is supported on the upper end of thepile 1 during the pile-driving operation, is mounted in thelengthening piece 2 at a position some distance above the lower end of the lengthening piece. As a result of this arrangement, the lower end of the lengthening piece extends around the outer circumference of thepile 1 over some distance, for example a distance of 1 m, during the pile-driving operation, so that any attachments present at that location for subsequent anchoring of the pile or the like are protected during the pile-driving operation. - A
closing plate 8 surrounding thepile 1, which may or may not be fixed to the lengthening piece, may be provided at the lower end of the lengthening piece for preventing soil entering the lengthening piece during the pile-driving operation. - A lead-through or
bent tube 9 is passed through a hole formed in the wall of thelengthening piece 2 and fixed to the lengthening piece near the upper end of the lengthening piece. - The upper end of a
flexible pipe 11 is connected to the end of the lead-through 9 present in the interior of thelengthening piece 2 by means of arubber buffer 10. As is shown in Figure 1, theflexible pipe 11 freely extends in downward directions within thelengthening piece 2. In addition to theflexible pipe 11 as shown, a second flexible pipe (not shown) will be provided in a similar manner. Said flexible pipes are passed through holes formed in thehammering plate 7. - Before the
pile 1 is driven into the ground to a position below the ground level 3, theflexible pipes 11 are connected to the ends of thepipes 4 that are fixed to thepile 1, which pipes still extend above the ground level at that stage. In order to enable said connecting of the lower ends of theflexible pipes 11 to the upper ends of thepipes 4, ahole 12 is formed in the wall of the lengthening piece at a position below thehammering plate 7, so that the lower ends of theflexible pipes 11 and the upper ends of thepipes 4 are accessible via said hole for connecting thepipes 11 to thepipes 4. - One end of a further
flexible pipe 14 is connected to the end of the lead-through 9 extending outside thelengthening piece 2 by means of arubber buffer 13, whichpipe 14 is connected to agrout pump 15 with its other end. The other flexible pipe, too, will be connected to the grout pump in a similar manner. - While the
pile 1 is being driven into a ground to a position some distance below the ground level, grout can be pumped to the lower end of thepile 1 by means of thegrout pump 15 via theflexible pipes 14, the lead-throughs 9, theflexible pipes 11 and thepipes 4, as a result of which agrout envelope 16 is formed around thepile 1 in a manner which is known per se. Also as a result of the presence of therubber buffers flexible pipes - Once the pile has been driven to the desired depth, the
lengthening piece 2 can be pulled out of the ground, during which operation the ends of theflexible pipes 11 are pulled off thepipes 4, with theflexible pipes 11 possibly being severed from ends of thepipes 11 that remain behind on the upper ends of thepipes 4.
