Definitions

  • the invention relates to a sound-emitting device comprising a tool in the form of a pile driver and a workpiece in the form of a pile or sheet pile, the pile or sheet pile being provided for processing by the pile driver and a bellows on the pile driver to reduce noise emissions and / or the driven pile, respectively the sheet pile, is arranged, the bellows at least substantially surrounding the sound-emitting area of the tool and workpiece and the bellows being designed as corrugated bellows.
  • Sound-emitting devices are known from the prior art. So are z. B. pile driving devices for driving a pile or sheet pile into the ground are known.
  • the pile driver itself is here by the boom z. B. held a vehicle displaceable in the vertical direction.
  • the pile driver is guided by a guide post, which is also held by the boom of the vehicle.
  • the pile driver itself has a pile hood, with the pile hood sitting on top of the pile as part of the pile driver.
  • the object on which the invention is based is to achieve a significant reduction in sound emission in sound-emitting devices, this being done with the simplest possible means.
  • the bellows be designed as a corrugated bellows.
  • a corrugated bellows has a similarly simple structure to a bellows, but ensures a significantly higher level of sound absorption.
  • the bellows comprises a plurality of elements which are arranged in a row in cross section and which are undulating and which are connected to one another in the region of the transition from one undulating element to an adjacent undulating element; the wave-shaped elements are closed in a ring.
  • a corrugated bellows is formed from several elements with a wave-shaped cross-section, which are arranged in series with one another and which are connected to one another by sewing and / or gluing, the wave-shaped elements also being ring-shaped for the circumferentially closed casing of the sound-emitting device are closed.
  • the inlet frames are designed to be circumferential in a ring shape.
  • the edging frame not only results in a more stable connection between two wave-shaped elements, but also gives the bellows overall greater stability, in particular against buckling.
  • the ring-shaped element which is undulating in cross section, is formed from at least two ring segments, the two ring segments being connected to one another; the connection can be made by sewing and / or gluing.
  • the wave-shaped element has at least one reinforcement coated with an elastomer, wherein the reinforcement is advantageously designed as a material, in particular as a fabric.
  • the element which is wave-shaped in cross section, has two leg areas and a web area.
  • a first and a second leg track made of a reinforcement coated with an elastomer to be provided in the leg area, the two leg tracks being connected by a web made of reinforcement also coated with an elastomer.
  • the connection is also advantageously made here by gluing and / or sewing.
  • the production of the waveform in a ring segment e.g. B. a semicircular ring segment, is particularly easy to accomplish. This in so far as no circular paths have to be prepared for the leg area, but only semicircular paths. Not only is this easier, but it also saves material.
  • a sound-emitting device comprising a pile driver and a pile driver, e.g. B. a driven pile or a sheet pile, with a corrugated bellows, as has been described above.
  • the pile driver forms the tool, the pile driver the workpiece.
  • the corrugated bellows is connected by at least one holder to the ramming member or the ramming device and here in particular the ram hood of the ramming device. It is advantageous if the ram hood of the piling device, which is the end of the Driving pile or the sheet pile surrounds like a cup, is connected to the corrugated bellows. This in so far as an essentially tight seal can then be achieved in the upper end area of the driven pile.
  • the holder can in this case advantageously be formed by the upper, last edging frame of the corrugated bellows, which in this respect can be screwed to the end face of the ram hood to the ram member.
  • the upper border frame then only covers a leg path.
  • an edging frame can likewise be provided, with which the corrugated bellows stands on the floor and to the extent that the wear on the bellows itself is reduced in this area. From this it becomes clear that the sound-emitting area of the piling device and the driven pile or sheet pile is encased not only tangentially all around, but also over the length of the pile, through bellows with an annular cross-section during the driving of a ram link into the ground.
  • corrugated bellows which is advantageously attached to the end face of the ram hood, is pulled over the length of the ram member and ultimately the corrugated bellows rests on the ground with its lower end.
  • the corrugated bellows is gradually shortened as the ramming progresses.
  • the guide post 3 has on its upper end a traverse 4 with several deflections for a cable pull 5, on which the pile driver 10 is arranged to be movable in the vertical direction.
  • the pile driver 10 has at its lower end the bellows 20, which in Fig. 1 is shown in the contracted state.
  • the driven pile 12 can be seen below the corrugated bellows 20, over which the corrugated bellows 20 is slipped over the entire length for the purpose of soundproofing.
  • the pile driving device 10 which is mounted on the guide pile 3 so as to be longitudinally displaceable, has at its lower end the driving hood 14, which is cup-shaped and rests on the upper end of the driving pile 12.
  • the corrugated bellows, designated as a whole by 20, is arranged on the end face of the ram hood 14.
  • the corrugated bellows 20 extends over the length of the driven pile 12 down to the floor 7, the corrugated bellows standing on the floor 7 at the lower end. This means that the driven pile 12 is essentially hermetically sealed by the corrugated bellows 20 over its circumference and over its length. In the course of driving the driven pile 12 into the Bottom 7, the corrugated bellows 20 is compressed in the axial direction in accordance with the progress of the ramming.
  • Fig. 3 shows the corrugated bellows 20 in a shortened representation. It can be seen that the corrugated bellows 20 comprises a plurality of wave-shaped elements 22 connected to one another in series, which are connected to one another in the region of the transition from one wave-shaped element to the adjacent wave-shaped element. Such a wave-shaped element 22 and its connection to the adjacent wave-shaped element 22 is shown in accordance with the illustration FIGS. 4 and 5 refer to.
  • the two wave-shaped elements 22 are not only connected to one another by gluing and / or sewing, but also advantageously by a border frame labeled 24 , which encompasses the transition area between two wave-shaped elements in a closed, circumferential manner.
  • the last upper edging frame 24 can be provided for attachment to the pile hood 14. This means that the corrugated bellows 20 with the last upper border frame 24 is in particular screwed to the end face of the cup-shaped pile hood 14 in the transition to the driven pile 12. It can also be provided that the corrugated bellows 20 with the last lower border frame 24 stands up on the floor 7 in order to reduce wear.
  • the corrugated bellows 20 has two semicircular ring segments 27 to form the annular, undulating elements 22, which are sewn and / or glued to one another in an overlapping manner at the joints 29 to form the annular, undulating element 22.
  • the wave-shaped element 22 has two leg regions in cross section, which are marked by the arrows 31 and 32.
  • the wave-shaped element 22 has two leg regions in cross section, which are marked by the arrows 31 and 32.
  • first and a second leg web 33, 34 coated with an elastomer which are connected in the web or apex region 35 by a third web 36 coated with an elastomer by sewing and / or gluing.
  • a respective edging frame 24 is provided, which encompasses the leg paths of two adjacent wave-shaped elements 22 in a ring-shaped manner.
  • a fastening support 40 is used as a layer of material, e.g. B. as a woven or knitted fabric, provided, the reinforcement carrier 40 at least on one, but advantageously on both sides, a layer 42 made of an elastomer, for. B. EPDM.
  • a plurality of fastening supports 40 can also be provided one above the other, the individual fastening supports being connected to one another by layers 42 of elastomer. That is to say, the reinforcement support or supports 40 as individual layers are embedded on all sides in layers 42 made of elastomer.
