Definitions
- the invention has for its object to provide means using which a hole of preselected dimensions can be made in the ground in very simple manner, wherein, otherwise than with a ground auger, the material from the hole does not come to lie on the ground and then has to be carried away, but remains present in the ground and wherein the immediate area of the hole has undergone a considerable compacting.
- the invention also has for its object to provide facilities which enable use to be made for this purpose of known drive devi ⁇ ces.
- a further object of the invention is to offer provi ⁇ sions using which holes can be made with a very high degree of precision, even by untrained personnel.
- the invention now provides a tool for making holes in the ground comprising a ram tip and coupling means for con- necting to a drive device, for instance a hydraulically or pneumatically operating tool driving machine or a vibrator operating for instance with eccentrically placed rotatably drivable masses for successively exciting the ram tip in the direction of the free end by vibration or percussion.
- a drive device for instance a hydraulically or pneumatically operating tool driving machine or a vibrator operating for instance with eccentrically placed rotatably drivable masses for successively exciting the ram tip in the direction of the free end by vibration or percussion.
- the tool has the feature that the free end of the ram tip has a first portion with a substantially conical form.
- a very effective force transfer onto the ground is herewith achieved, with one the one. hand a desired dis ⁇ placement and on the other a desired compacting of the ground with the displaced ground material.
- the tool has the further feature that a second frustro-conical portion with a smaller apex angle than the first portion connects onto the conical free end.
- a further effective displacement of the ground is hereby performed in combination with the said compacting.
- An embodiment having the feature that a third, frus ⁇ tro-conical portion with a smaller apex angle than the second portion connects onto this second portion has the great advantage that after making the hole it is easily removed therefrom by being retracted.
- the conical form which in practice can differ relatively little from a cylindrical form, for example by a few degrees, results in the air being able to enter easily into the space between the formed hole . wall and the tool.
- the embodiment is recommended in which the ram tip is hollow.
- the ram tip is hollow.
- use is preferably made of mutually connected reinforcing ribs received in the hollow ram tip. It may be useful to mechanically separate the transmission of forces from the coupling means to the free end of the ram tip from the force transmission through the wall of the ram tip. To this end the tool can have the feature that the ribs rest against the wall of the ram tip but are not connected there ⁇ to.
- the tool displays the feature that a central elongate element such as a rod or a tube extends between the coupling means and the free end of the ram tip for transmitting excitation forces from the coupling means to that free end.
- a central elongate element such as a rod or a tube extends between the coupling means and the free end of the ram tip for transmitting excitation forces from the coupling means to that free end.
- This variant can for instance be embodied such that the ram tip -is partially filled with more or less particulate material.
- This material can for instance contain sand or iron, in general preferably a cheap and heavy material.
- the tool preferably has the characteristic that at least the outer surface of the free end consists of a hard, wear-resistant and rugged material such as manganese steel. Other types of steel, particularly steel types rich in car ⁇ bon, can also be considered suitable. Less extreme demands are made on the second and third portions than on the first portion.
- the outer surfaces of the second and third portion can for instance consist of steel- 52.
- An embodiment for use with a drive device whereof the drive end comprises a pivot joint can preferably have the feature that the coupling means comprise a pivot joint of which the shaft lies substantially perpendicular to the shaft of the pivot joint forming part of the drive device.
- the freely suspended tool makes a vertical hole in the ground.
- the axis of the ram tip must intersect both pivot shafts. If during making of a hole in the ground the ram tip encounters an obstacle, for instance a rock, it can avoid this obstacle as a result of the cardan suspension.
- the coupling means take a substantially cardan form.
- the tool has the charac ⁇ teristic that the coupling means can be coupled to the drive device by means of a coupling block which is mechanically connected for instance by pressing, shrinking or welding to a tool such as a hammer or chisel for coupling to the drive device.
- a coupling block which is mechanically connected for instance by pressing, shrinking or welding to a tool such as a hammer or chisel for coupling to the drive device.
- the tool according " to the inven ⁇ tion can very easily be made suitable for use with any suit- able drive device.
- the manufacturer of the tool can for instance acquire a hammer or chisel which fits into a drive device that a customer has at his disposal.
- This hammer or chisel is then connected in appropriate manner to the coup ⁇ ling block, which in turn has suitable coupling means avail- able for coupling to any tool according to the invention.
- the tool displays the characteristic that the block has a transverse recess and the ram tip likewise has a transverse recess in the corresponding zone, in which recesses a coupling pin can be inserted from outside after they have been placed mutually in register.
- This coupling is operationally very reliable and inexpensive and has the advantage of allowing of easy disconnection into components when desired, for example for changing tool.
- the tool has the feature that at least one of both recesses has a greater length axially than the coupling pin, such that the ram tip is axially displaceable to a limited extent relative to the coupling block.
- This embodiment can have the advantage that registering of the recesses takes place easily so that coup ⁇ ling can be effected more rapidly.
- a mechanically looser coupling can also provide the advantage that diverse com ⁇ ponents of the drive device are subjected to a smaller mecha- nical load.
- the co- acting contact surfaces of the ram tip and the coupling block can be rotationally symmetrical and for one of the said reces ⁇ ses to extend over the whole periphery.
- the tool can if desired rotate round its longitudinal axis.
- the invention further relates to the coupling means as specified " above and in the claims 18-20.
- the invention also relates to a method for making holes in the ground. This method is characterized by the following steps, in appropriate sequence, of;
- the invention also relates to a method of the type described above for manufacturing a tubular foundation in the ground.
- This method is characterized by the steps of: (9) making a hole with the method as claimed in claim 22, the depth of which is smaller than the depth of a tubular foundation for manufacture;
- the method can be characterized by (13) performing step (9) such that the depth of the hole amounts to roughly half the depth of the finished foundation.

- Fig. 1 shows a lifting device 1 carrying a hydraulic tool driving machine 2.
- This tool driving machine 2 carries a chisel 3 which in a manner to be further described bears a ram tip 4.
- the device 1 comprises a hydraulic pressure source for driv ⁇ ing the device 2 by means of flexible hydraulic lines 6, 7 such that the chisel is excited with vibration or percussion.
- the ram tip 4 is placed at the desired position, the tool driving machine 2 is set into operation by appropriate energizing of the hydraulic source and the ram tip is moved downward while vibrating through control of the hydraulic lifting cylinders generally designated with 8.
- the ground material is hereby displaced, thus creating a hole, the immediate area of which has under ⁇ gone a considerable compacting.
- Figure 2 shows the internal structure of the ram tip 4.
- the lowest, first portion 9 of the ram tip 4 has a substantially conical shape. Connecting thereto is a second portion 10 with the form of a frustrum cone. The apex angle of this cone is smaller than the apex angle of the first portion 9.
- a third, frus- tro-conical portion 11 Joining onto this second portion 10 is a third, frus- tro-conical portion 11 which has a smaller apex angle than the second portion 10.
- the ram tip 4 is hollow. It is internally reinforced by reinforcing ribs 12 and 13 located respectively above and below a strengthening partition 14.
- the ribs 12 extend from an inner tube 15 to the wall of the. third portion 11, to which they are fixedly welded, and have a mutual angular distance of approximately 90°.
- the ribs 13 are correspondingly placed and extend between a slimmer inner tube 16 and the wall of the respective portions 11, 10 and 9.
- the tubes 15 and 16 connect onto the partition 14 and in this manner connect the driven top end of the ram tip 4 to the first portion 9, thereby ensuring a very effective trans ⁇ fer of the percussion forces.
- the outer surface of the first portion 9 consists of manganese steel, while the outer surfaces of the second portion 10 and the third portion 11 consist of steel-52.
- the ram tip 4' according to figure 3 is virtually identical to the ram tip 4 as in figure 2. It differs however from the ram tip 4 in the fact that the ribs 13 rest against the wall of the ram tip 4', but are not connected thereto. In this manner the transmission of forces from the top part of the ram tip 4* to the first portion 9 is mechanically separa ⁇ ted from the force transmission through the wall of the ram tip 4 1 . According to circumstances this can result in an even greater effectiveness of the tool.
- Figure 4 again shows the ram tip 4. In this embodiment it is partially filled with sand.
- the ram tip 4 comprises two divided spaces, designated 17 and 18 respectively.
- the space 17 is bounded by the wall of the portions 9, 10, 11 and the partition 14, while the space 18 is bounded by the partition 14, the wall of the upper part of the third portion 11 and the end wall 19.
- the respec ⁇ tive sand masses 20 and 21 are not initially set into motion due to their freedom of movement in the spaces. Owing to their inertia they do however subsequently exert a percussive force. This configuration can also increase the effectiveness of the tool according to the invention.
- FIG. 5 shows the ram tip 4, wherein however the spaces 17, 18 are partially filled with the respective iron masses 22 and 23. These masses consist of waste material.
- Figure 6 shows the ram tip 4 which is suspended from the tool driving machine 2.
- the tool driving machine 2 can be suspended for free swinging in all directions from fixing ears 25 (see figure 1) which form part of the lifting device 1.
- the ball and socket joint is provided at its top with a fixing ear 26.
- Figure 7 shows a substantially cardan coupling 27 with which the tool driving machine 2 is suspended from the lift ⁇ ing device 1.
- a coup ⁇ ling plate 30 onto which are fixed two blocks 31.
- Connected to these blocks 31 by means of pivot shafts 32 is a thus pivotable block 33 through which extends a pivot shaft 34 that is connected to the ears 35 which are in turn connected to a coupling member 36 for coupling to the lifting device 1.
- FIG 8 shows the manner in which the ram tip 4 can be coupled to the tool driving machine 2.
- the tool driving machine 2 carries a chisel 3. This is coupled by means of a coupling pin 37 to a drive means (not shown) .
- An annular coupling block 38 is arranged on the chisel 3 by pressing, shrinking or welding. This coupling block 38 has an annular recess 39.
- the ram tip 4" bears at its top end a coupling ring 40 which fits round the annular coupling block 38 and is provided with through-holes extend ⁇ ing in tangential direction for receiving two coupling pins 41 which, in the inserted position, are situated at a loca ⁇ tion such that they extend through the annular recess 39.
- the coupling between the ram tip 4" and the tool driving machine 2 is thus ensured, wherein a certain axial freedom of move ⁇ ment is obtained by an enlarged axial dimension of the recess 39.
- Figure 9 shows a schematic side view of a crash bar- rier 48 which is supported in foundations 46 according to the invention.
- Figures 10-14 show schematic vertical sections through a hole 42 made in the ground 5 by a ram tip 43.
- the depth of the hole 42 is designated with 1/2T. This will be discussed further with reference to figures 13 and 14.
- the ram tip 43 is removed from the hole 42.
- a concrete mass 44 is then poured into the hole 42. The filling with concrete takes place in this embodiment such that the hole is approximately half filled with con ⁇ crete.
- the ram tip 43 is replaced in the hole 42 in the manner shown in figure 12 and the hole is made longer by appropriate driving of the tool driving machine (not drawn here) .
- the concrete is distributed along the ram tip 4 so that a tubular concrete casing 45 is created.
- the total length to be reached equals T.
- the concrete has also partial- ly penetrated into the ground material, whereby the casing 45 is firmly anchored in its immediate surrounding area.
- FIG. 16 and 17 show a variant, according to which the ramp tip 4* is connected by flexible pull resistant elements, like chains 48, with a tool driving machine 49. These elements 48 serve for lifting up the ram tip 4 out of the hole.
