Definitions

  • the invention relates in the first instance to a process for placing a concrete pile in the ground, in which a casing with driven rotating screw fitted on the bottom end thereof is screwed into the ground and after the desired depth has been reached is raised, and in which concrete mixture is fed into the casing during this upward movement, said mixture being conveyed into the hole formed through a passage at the bottom end of the casing which is closed during the screwing in.
  • the screw in this known method is closed, as a result of which the earth during screwing in is displaced and compacted around the casing.
  • the chance of the wall of the driLLed hole around the casing collapsing is reduced through the compacting.
  • a disadvantage of the known process is that a high resistance is encountered during screwing into the ground. This can be so high that it is virtually impossible to penetrate through a hard bearing Layer to the desired depth.
  • Another disadvantage of the known process is that when the casing is being withdrawn from the drilled hole the screw drill is turned in a direction opposite to the direction of drilling, in which case, if the upward puLLing movement is not adapted to the pitch of the driLL, the ground is pressed downwards. This can Lead to a conically tapering pile shoe.
  • the object of the invention is to avoid the above- mentioned disadvantages, and to this end the process mentioned in the preamble is characterized in that the screwing of the casing into the ground takes place by a screw fin with openings between the windings, and in that the ground directly above the screw is compacted by a displacer with a closed spiral part having the same screw direction as the drill screw and a spiral part above it with the opposite screw direction, while the casing is rotated in the original screw direction during the pulling up thereof.
  • the screw fin draws the casing relatively easily into the ground.
  • the compacting of the ground takes place as soon as a part of the drill has penetrated into the ground.
  • the displacer will not have a greater external diameter than the screw fin. In principle, the maximum diameters are the same.
  • the driLL can penetrate through hard intermediate Layers and through into a hard bearing Layer. Since the casing is turned in the same direction when going into and coming out of the ground, no earth is pumped downwards.
  • the concrete pile wiLL be sound and cylindrical right to its bottom end.
  • a quantity of sand placed on the surface it is usually preferable for a quantity of sand placed on the surface to be moved into the hole through a screw provided on the top part of the casing, with screw direction opposite to that of the screw at the bottom end of the casing. This sand pressed from the surface into the hole ensures a compacted sand mantle around the casing. Negative adhesion (earth sinks more than piLe) is countered in this way.
  • the invention also relates to a tubular screw driLL in particular intended for use in the process.described above.
  • This driLL has according to the invention a screw fin which extends between one end of the driLL and a displacer successively comprising a closed spiraL part having the same screw direction as the fin and a closed spiral part having the opposite screw direction.
  • the casing provided with a screw driLL can have at a distance from the displacer one or more screw fins whose screw direction is opposite to the screw direction of the fin of the screw driLL.
  • the casing can consist of a number of sections which are Linked together by a simple screw coupling, with the angle of inclination of the screw being at Least 30 degrees relative to the horizontal.
  • the coupling can be detached by turning in the opposite direction.
  • the earth driLL to be used in the process according to the invention is shown in Fig. 2. It is made up of various parts.
  • On the under side is the shut-off point 1 of the casing 2 which prevents water or earth from penetrating into the casing.
  • This point 1 is connected to the casing by means of a screw connection with sharply slanting heads of screw.
  • Wound around the casing 2 is a screw fin which is connected to the casing by welding.
  • the displacer consisting of a bottom part 4 and a top part 5.
  • the part 4 has a closed screw whose external diameter increases spiraLLy from the external diameter of the casing 1 at the Lowest point to a diameter equal to the external diameter of the fin 3 at the highest point.
  • the displacer part 5 also comprises a closed screw, but the diameter now reduces spiraLLy to a value equal to the external diameter of the casing 2.
  • a characteristic is that the screw direction of screw fin 3 is the same as that of part 4, while the screw direction of part 5 is opposite to that of part 4. It is also characteristic that the displacer parts 4 and 5 never have a diameter which is greater than that of the screw fin 3.
  • the driLL is coupled to other sections of the casing 2.
  • the casing 2 with the screw driLL at its bottom end must be rotated, and it must be possible to move it verticaLLy downwards and 0 upwards.
  • This apparatus is indicated schematicaLLy in Fig. 1.
  • the casing At the top end of the casing 2, at the point which wiLL stiLL just penetrate into the ground when the concrete pile is being made, the casing is provided with two fin windings 6, 7 at a distance from each other. These fin windings have a screw direction which is opposite to that of the screw fin 3.
  • the casing 2 can be rotated by the driLLing table 8.
  • the casing 2 is connected by means of a universal joint 9 to the hose 10 of a concrete pump.
  • the table 8 is fastened in guiding fashion to a mast 11. This mast must be able to absorb the maximum moment of the table and must thus be fixed to a machine of sufficient stability. Since this machine must also be able to move over the trench, a caterpiLLar vehicle 12 is preferably selected for it.
  • the drilling table 8 can be driven hydraulically or eLectricaLLy, in which case moment and speed are preferably regulable.
  • a diesel engine 13 placed on the vehicLe 12 can supply the necessary hydraulic pressure or electric current.
  • the casing 2 must not only be rotated, but must aLso first be moved downwards and then pulled upwards. Apart from the torque, the weight of the casing 2, 3, 4 and 5 and of the driLLing table 8 alone is sufficient for the movement downwards of the casing 2.
  • a great upward puLLing force is needed in order to be able to draw up the driLL from the ground. This force is supplied in the present case by a winch 14 which is fastened by means of a tackle to the mast and draws the driLLing table upwards.
  • a hydraulic jack which can exert force on the casing with a cLamp.
  • the centre Line of the casing 2 is first taken so as to be perpendicular above the place where the pile has to go in the ground.
  • the casing 2 is closed off at the bottom end by the shut-off point 1, and the casing 2 is Lowered until it rests on the ground.
  • a quantity of coarse-grained earth sand or graveL is brought in.
  • the driLLing table 8 is put into operation and drives the casing 2 in such a way that the screw fin 3 puLLs the casing 2 downwards.
  • the casing 2 penetrates into the ground.
  • the earth fiLLs the space between the windings of the fin 3.
  • the earth with a volume equal to the volume of the pipe part which has penetrated into the ground is dispLaced. In this way, the pore voLume of the ground round the periphery of the casing 2 is reduced. If the point sinks Less than the pitch of the fin 3 per revolution, then the casing 2 works through the screw fin as a conveyor screw and transports earth upwards.
  • the driLL point 1 remains behind in the ground, and the concrete mixture under pressure, via the casing 2, fiLLs the space which is produced under the driLL in the ground.
  • the concrete pressure helps the driLL here to press upwards (see Fig. 6). Since the casing 2 continues to turn in the same direction during its upward movement, the earth remains between the windings of the fin 3, and from the beginning of the upward movement of the casing a cylinder is formed in the ground. Above the fin 3, the displacer part 5 with opposite screw direction presses back LateraLLy the earth which has faLLen in against the displacer. The only earth which is brought up out of the hoLe is thus the part which is Lodged between the windings of the fin 3.
  • the earth previously dumped on the surface is conveyed into the hole.
  • the earth around and underneath the concrete pile is not released from tension at any point.
  • WhiLe the casing 2 is driLLing into the ground, the earth is displaced over a volume equal to the content of the casing 2, while during driLLing out the displacer part 5 displaces an earth cylinder with a diameter equal to the Largest diameter of the screw box of the displacer.
  • the concrete pressure maintained by the pump ensures that underneath the casing 2 no release of pressure on the earth can occur.
  • a cylinder of concrete is formed in the compressed earth (see Fig. 7).
  • the mantles 19, 20 and 21 are shown round the concrete piLe.
  • the mantle 19 corresponds to the quantity of earth which was transported by the screw blades 6, 7 into the hoLe.
  • MantLe 21 is formed by the displacer part 5.
  • the mantle 20 is Less wide and is formed by displacement of a volume of earth corresponding to the volume of the casing 2. The material caught between the windings of the fins 3 is taken up.
  • the screw connection preferably has a great sLope, for example the angle of the screw relative to the horizontal being at Least 30 degrees. This makes detachment of the casing sections extremely simple.
  • the moment which has to be suppLied for the casing to be able to penetrate deeply enough into the ground depends on the ground resistance and the diameter of the concrete pile to be formed.
  • the casing Length along which the fin 3 extends, the pitch of the parts 3, 4 and 5, and the diameter of the casing 2 play a not insignificant role in this.
  • the possibility of producing piLes of specific bearing power by a suitable choice of these values, with minimum output, is an important advantage of the invention.
  • Layer 27 is a brought-in Layer of coarse sand, which is needed to permit carrying out of the work in good transport conditions;
  • Layer 28 is Loose cLay,
  • Layer 29 is sand with good resistance, but not thick enough,
  • Layer 30 is a Low consolidated cLay, and
  • Layer 31 is sand of good resistance and sufficiently thick for anchoring of the concrete piLes in it.
  • the screw blades 22-26 carry the Large heap of coarse-grained sand which was brought in around each piLe down to the bottom, and it is displaced by the displacer part 5 into the surrounding ground when the rotating casing 2 is drawn out of the ground.
  • the mantle 19 of compressed sand can widen in the process and reach up to the first good sand Layer 29.
  • the subsidence in the original Loose Layer wiLL be greatly reduced, even if the surface is Later Loaded.
  • the mantles around the concrete piLe give the foLLowing advantages: they reduce the concrete Loss in slack Layers, they increase the resistance of the driLLed hole against coLLapsing, and they avoid the occurrence of negative adhesion.
  • the casing is driLLed by an open screw fin over a certain Length into the ground before the ground is compacted by a displacer. It is also important for the casing to be rotated in the original screw direction while it is being drawn up.
