Definitions

  • Piling devices which comprise a frame which is equipped with guides for a ram, which with a rotating Chain can be pulled up and along the guides on one in the Earth rod to ram falls.
  • the chain is equipped with drivers, into which the ram automatically engages to pull up while it automatically unlatches in the raised position.
  • Such a thing Piling equipment is shown for example in EP-A-0 569 339.
  • Such rammers have the disadvantage that in addition to Ram a frame with the drive means and the corresponding guides must be carried, which has a considerable weight. There such ramming probes often have to be carried out in the field, which is rather impassable is a transportation of this facility to the Location associated with a lot of effort.
  • the poles used to ram into the ground have one certain length on. These can be extended with additional poles become. In the above example, it is therefore necessary for each The piling device is lifted off the last bar must be so that the rod can be extended by another rod can. Then the pile driver has to be put back on the newly inserted pole be put on. This involves a relatively large amount of work, it is practically not possible to use a ramming probe Have the device carried out by a single person.
  • the anvil is advantageously made of an annular body formed, which can be fastened to the rod by means of wedges, which enables the The anvil can be adjusted in height with little effort, using the attachment is optimal.
  • the top end region of the ram is advantageously included provide an end cover so that between the piston and end cover a room is formed in which the compressed air can be supplied, to raise the ram.
  • FIG. 1 is to be rammed into the ground 1
  • Rod 2 an anvil 3 put over.
  • This anvil 3 consists of one annular body 4, the wedges 5 on the rod 2 on a selectable Height is fixed.
  • the pile driver 6 is mounted on the anvil 3.
  • This comprises a piston rod 7, which is hollow-cylindrical is and through the longitudinal opening 8, the rod 2 is guided.
  • the piston rod 7 is equipped with a piston 9.
  • a valve device 16 is arranged in the end cover 13, while an inlet opening 17 for compressed air is provided in the ram 10, which opens into the space 18 between the piston 9 and the end cover 13. Furthermore, there is a ventilation opening in the lower end region 14 of the ram 10 19 attached. The operation of this valve device 16 the inlet opening 17 and the vent opening 19 will be precise later described.
  • Fig. 3 shows the pile driver 6, which corresponds to Fig. 1 on the Piston rod 7 is supported on the anvil 3.
  • the ram 10 is in the lower position, which is taken when, for example, a blow to the anvil 3 is done.
  • Drain openings 28 attached in the illustrated position of the ram 10 are closed by the annular disc 27, for which purpose this with a Sealing washer 29 is provided.
  • the annular disc 27 is through made of bolts 30 guide means guided such that they differ from End cover 13 can move away against the piston 9 to the To be able to release drain openings 28.
  • the ram 10 is started up until one in the Ram 10 attached vent 35 has passed over the piston 9, whereby the room 18 is connected to the environment. Once that position is reached, there is a drop in pressure in space 18, the compression springs 32 cause the annular disc 27 to move away from the end cover 13 and are pressed against the stops 31, the drain openings 28 in End cover 13 are opened, the ram 10 falls down and strikes anvil 3. This impact, which is caused by the anvil 3 is transferred to the rod 2, the rod 2 by a certain amount in rammed the floor.
  • FIG. 5 shows that at this embodiment in the end cover 13 six over the circumference distributed outlet openings 28 are provided. Furthermore are three guide bolts 30 attached to guide the annular disc 27. Of course, other arrangements could also be used. Of furthermore, in this embodiment, a ram 10 is used, which consists of a thick-walled hollow cylinder is formed. Here, too, there would be other forms possible, it would also be conceivable for additional weights to be attached to the ram could become.
  • An embodiment of such an inventive Piling equipment can, for example, have a total weight of around 35 kilograms exhibit.
  • the fall height of the ram is about 20 cm.
  • This Piling equipment is very easy to use, which is easily done one person can be carried out.
  • For commissioning can be in the Piling device and the anvil inserted a rod to be rammed into the ground the anvil is attached to the rod, the rod is inserted into the vertical position, the ramming process can begin.
  • the pile driver by the very simple lifting device can be lifted off the anvil.
  • To extend one rod by another becomes only the one that can be placed on the rod Part 20 is removed from the rod that has already been partially rammed into the ground and placed on the extension rod inserted in it. So it is not necessary, the piling device every time the pole is extended to be lifted off the shelf completely, which makes operation very easy becomes.
