Definitions
- the invention relates to a ram boring machine Manufacture of earth bores using the for running monitoring an integrated measuring and transmission unit is provided, whose signals are picked up by an above-ground receiver will.
- Ram boring machines are primarily used for trenchless laying of pipes, especially pipes in the ground and need run monitoring and control that it allow the device to be brought as precisely as possible to the destination.
- the device must drive around obstacles on the ground are or lead just like different earth formations often deviations in direction, that of careful Correction is necessary, as otherwise it is in particular at large distances to large deviations from the target is coming.
- the device tip serves stones and that To penetrate or penetrate soil and to oust; it is therefore a great burden from that surrounding soil.
- For one such a starting pit is - for example in front gardens, under sidewalks or in existing inspection shafts - mostly little space available. This causes the devices to be as short as possible, to be able to get by with narrow starting pits. Analogous the same applies to the target pit.
- the invention is therefore based on the problem of the mechanical stress on the sensitive To keep the measuring and transmitting unit as small as possible and - in cases where it is due to the operating conditions it depends - the device length as short as possible to keep.
- the solution to this problem is accordingly on the one hand in that the transmitter so far from the striking tip to arrange as possible. This will be an arrangement in the direction of advance before the rear stop for the Percussion pistons are most likely to be fair.
- the transmitter is practically outside of the device housing, for example where the connection between the Device housing and a pull tube.
- Such Arrangement solves simultaneously - at least for Part - the problem of additional space; because the transmitter can be inside a hollow cylindrical Connection piece or a ring for the pull tube are located; it can be cast into the ring.
- the Transmitter in an elastic mass, preferably made of silicone or be embedded in polyurethane.
- the device housing can in the area of the transmitter with a plastic cover be closed off for the transmitter signals is permeable, or it is in the area of the transmitter the steel parts surrounding the transmitter slots for the Transmitter signals arranged.
- the measuring unit is preferably equipped with an inclinometer, with whose help it is possible to find directional deviations in the vertical, for example, in the area of surface unevenness or ground obstacles or changing Determine soil layers.
- the ram boring machine corresponds in principle Structure and its mode of operation that in German Patent 21 57 295 device described; it owns a housing 1 with a striking tip 2 and a striking piston 3.
- the percussion piston 3 has in its rear Part of a compressed air chamber 4 with radial control openings 5 and is longitudinally movable on a head tube 6 performed in the device housing 1; he gives his Impact energy when hitting the front wall 7 of the Device housing 1 from.
- a stop ring 8 In the rear part of the device housing there is a stop ring 8 through which Steering tube 6 protrudes beyond the stop ring is connected to a compressed air hose 9.
- a stop ring 8 Immediately behind the stop ring 8 is in a sleeve 13 connected to the device housing 1 Slot 10, in the area of an annular insert 11 is arranged.
- the slot 10 can with a lid sealed or potted with a non-conductive mass be, which does not hinder the transmitter signals.
- the Insert 11 contains the transmitter and sits in the sleeve 13, which also serves as a connection for a pull tube 12 serves that of the ram boring machine in the created by him Earth hole is pulled.
- the annular insert 11 consists of an elastic and shock absorbing plastic; he has one Pocket 14 for a block 15, preferably from a non-conductive elastic mass, for example silicone.
- a non-conductive elastic mass for example silicone.
- the percussion piston 3 moves when the device is propelled under the influence of the compressed air hose 9 and the control tube 6 fed into the percussion piston chamber 4 Compressed air in the device housing 1 back and forth; he gives its impact energy essentially exclusively the end wall 7. Only in the case of a relative reversal of the direction of movement that is rarely necessary the percussion piston 3 is controlled so that it with his rear end meets the stop ring 8. More details this results from the German patent specification 21 57 295. It follows that the transmitter 17 with its sensitive Electronics and also the inclinometer 18 only extremely rare immediate impact of the ramming Percussion piston 3 is exposed. It is therefore subject to a much lower mechanical stress than one arranged in the conventional manner in the striking tip 2 Channel.
