Definitions
- the invention relates to a ram for ramming pipes such as protective or conduit pipes.
- jacking pipes generally requires a starting pit or a starting shaft in which the ram and jacking pipe are prepared.
- German utility model 87 07 158 that the ram can no longer be engaged directly or by means of a ramming attachment in the rear tube end, but must be arranged in the jacking tube. In this way, the required length of the launch pit is essentially determined only by the length of the jacking pipe.
- the known inner ram is enclosed by a cladding tube arranged in the jacking tube, the conical impact tip of the ram positively engaging in an inner ring arranged at the forward end of the cladding tube in the direction of advance, so that the thrust force of the ramming over the either movable or with the ram housing rigidly connected impact tip on the inner ring and thus transmits the enveloping tube.
- the invention has for its object to improve the internal ramming of pipes, in particular to reduce the mechanical effort.
- this object is achieved in that the rear end of the ram is preferably positively connected to the rear end of the jacking tube in the direction of advance, for which purpose the rear end of the ram can advantageously be provided with a tapering approach to the direction of advance. Due to the connection according to the invention of the thickened rear end of the ram or the ram housing with the rear end of the jacking tube, the thrust of the ram is introduced directly, ie without deflection as jacking force into the jacking tube. This does not require a tube which additionally envelops the ram and is also provided with a collar, or a tensioning device which couples the jacking tube to the ram in order to avoid impact impacts.
- the rear end of the ram By means of a connecting piece, such as a ram cone or a ram segment, between the extension and the jacking pipe, the rear end of the ram, thickened by the extension, can be adapted to different pipe diameters; it is only necessary to push one or more connecting pieces corresponding to the inside diameter of the jacking pipe onto the ramming attachment.
- a connecting piece such as a ram cone or a ram segment
- a ram 3 is arranged, which is supported with its conical striking tip 4 in a support ring 5.
- the rear end of the ram 3 has a tapering in the direction of the impact tip 4 approach 6 and a push-fit on the approach 6, formed as a ram cone 7, so that the rear end of the ram 3 over the approach 6 and the ram cone 7 with the rear End of the jacking pipe 2 is connected.
- FIG. 2 shows the attachment of a following pipe 2b to a jacking pipe 2a which is almost completely rammed into the soil 8.
- the following pipe 2b is in the starting position shown in a starting pit 9 and is supported on a base frame 12 by means of support rollers 11 arranged prismatically on bases 10.
- the rear end of the ram 3 is positively connected to the rear end of the follow-up tube 2b in the direction of propulsion via the conical extension 6 and the intermediate ram cone 7.
- the percussion piston is usually acted upon pneumatically, hydraulically or mechanically.
- compressed air is passed from a compressor (not shown) via an air hose 13 with an integrated reversing valve 14 into the interior of the ram 3.
