Definitions

  • the invention relates to a device according to the preamble of claim 1.
  • a device of this type is known from DE-OS 2 236 901.
  • this known device uses more than one vibrating tube on a common leader only in the event that the vibrating tubes are arranged in a line next to one another and are used to produce a narrow diaphragm wall in the ground.
  • a single vibrating tube can be used in the known device.
  • Guide blades can be arranged on both sides of the tip of the vibrating tube for better guidance in the ground.
  • Such a vibrating tube has a diameter of approximately 40 cm. This diameter cannot be increased significantly since experience has shown that it is the optimum for penetration of the vibrating tube.
  • the speed of penetration of a vibrating tube into the ground is greater, the smaller its diameter, the greater its vibrating frequency and the greater its vibration amplitude.
  • the interior of the hollow vibrating tube is used in the known device as a concrete feed tube, which is open at the bottom of the vibrating tube.
  • the concrete feed pipe is filled with pressurized concrete or the like during the penetration of the device into the ground so that no ground can penetrate into the open end of the feed pipe.
  • piles with a larger diameter are either introduced in such a way that they are poured and hardened outside the ground and then hammered into the ground by means of impact hammers with a high level of noise and vibration, or by lengthy drilling out of the ground beforehand with a drill and then the Concrete is filled into the resulting cavity.
  • the invention is intended to improve a device of the type mentioned at the outset so that piles with the cross-section of a vibrating tube of 40 cm in diameter substantially exceeding closed cross-sections, the smallest transverse dimension of which is ⁇ approximately 40 cm, are introduced into the ground in a simple and rapid manner can.
  • the vibrating tubes which are rigidly connected to the displacement box, cause the entire device to vibrate in such a way that it can effectively penetrate the soil.
  • the oblique sliding surfaces of the displacement box interact with the tips of the vibrating tubes to displace the soil.
  • the closed cross-sectional shape of the device ensures favorable compaction of the displaced soil.
  • the displacement box is preferably made of hollow steel sheet or the like.
  • a cross-sectional ratio in which the cross-section of the displacement box is approximately 1: 2 to the sum of the cross-sections of all vibrating tubes has proven to be particularly expedient, although this ratio is not essential for the device according to the invention.
  • Embodiments designed with two, three or four vibrating tubes are particularly advantageous.
  • a material feed pipe is preferably arranged in the displacement box, where it is best protected against damage and opens at the bottom near an opening of the displacement box. If it is to be avoided that soil penetrates the displacement box, the two openings can also coincide.
  • Claims 4 to 6 relate to advantageous refinements of devices for fixing the parts of the device to one another and to the leader carrying them.
  • the opening of the displacement box can be closed after taking up the soil and thus the penetrated soil can be pulled out with the device.
  • the displacement box is given a greater height so that it extends over the entire length of the vibrating tubes.
  • a material feed pipe 18 running parallel to the vibrating pipes 10 is provided in the middle thereof, which ends at the bottom in an opening 20 and has a feed line 22 at the top.
  • the displacement box 16 has at its lower end approximately in the region of the tips 12 of the vibrating tubes 10 sliding surfaces 24 converging obliquely downwards, which form an opening 26 directed downwards.
  • the opening 26 is located so that concrete or the like introduced under pressure in the material feed pipe 18 can flow out through the opening into the ground, while the device is pulled up again after the end of the lowering, so that the material completely clears the released cavity in the ground fills out.
  • Each vibrating tube is interrupted in its upper area in a manner known per se via a hard elastic coupling member 32 which largely dampens the vibrations generated by the vibrating motor, not shown, in the lower part of the vibrating tube in the section of the vibrating tube 10 located above the coupling member 32.
  • These upper sections of the vibrating tubes are connected to one another by a rigid support part 28, while those subjected to the vibrating vibrations lower sections of the vibrating tubes 10 are connected to each other and to the displacement box 16 by a hard elastic connecting member 30.
  • the connecting member 30 is preferably attached approximately at the level of the amplitude of the vibrating tube vibrations.
  • the vibrating tubes 10 are held stably in the recesses 14 of the displacement box 16 by the carrier part 28 and the connecting member 30.
  • FIGS. 5 and 6 has four parallel vibrating tubes 10, which are arranged in corresponding recesses 14 ′′ of a displacement box 16 ′′ and, with this, result in an approximately square overall cross section of the device with rounded corners formed by the vibrating tubes 10.
  • This device accordingly produces a very stable concrete pile with an approximately square cross section.
  • the inclined sliding surfaces 24 ′′ form a much larger opening 26 ′′ at the lower end of the displacement box 16 ′′, through which the material feed tube 18 exits and protrudes somewhat.
  • the opening 26 ′′ is essentially square and can be closed in the closed position shown in the left half of FIG. 6 by a likewise slidable closure slide 44 that can be moved in the axial direction of the device, ie parallel to the vibrating tubes 10.
  • the plate-shaped closure slide 44 has a central opening 46 which comprises the material feed pipe 30.
  • the piston rods 48 are pivotably articulated by two vertically acting hydraulic cylinders, which in turn are pivotally mounted at their upper ends on a holding bridge 52 welded firmly in the displacement box 16 ′′.
  • the holding bridge 52 carries a central ring 54 which surrounds the material feed pipe 18.
  • the hydraulic cylinders 50 are extended and the opening 26 ′′ is thereby closed.
  • the soil located inside the displacement box 16 '' is therefore taken upwards when the device is pulled, so that not only the lowering of the device due to the penetration of the soil into the displacement box 16 '' is opposed to less resistance, but also the filling the resulting cavity with concrete or the like. Is significantly facilitated.
  • the displacement box 16 ′′ extends essentially over the entire height of the vibrating tubes 10.
