Definitions

  • the invention relates to the production of an underground passage, such as a tunnel.
  • the invention is concerned in particular with the production of the underground passage in such a way that the objects present above it do not suffer any disruption.
  • Examples that can be mentioned are the production of tunnels below existing sections of rail, roadways and the like. In such cases it is extremely important that the existing sections are not in the least disrupted by slight subsidence and the like. The fact is that subsidence leads to poor conditions on the section of road or rail, and this makes travelling on it less comfortable, and can also lead to dangerous situations and even to section closures.
  • a further disadvantage is that the corresponding entrances and exits are relatively long, since their gradient percentage must remain limited. This also means that the potential excess water in the event of heavy rainfall is proportionately greater, which in turn gives rise to the need for providing fairly large water storage cellars. All this leads to relatively high costs, and sometimes, as a result of such long entrances and exits, the use of such tunnels is made difficult or even impossible if work has to be carried out in an existing environment which offers little room for manoeuvre or alternative routes.
  • the object of the invention is therefore to provide a method of the type described in the preamble in which these disadvantages are overcome. That object is achieved by means of a method for producing an underground passage, comprising the steps of:
  • the pipe sections can be driven into the subterranean ground in all kinds of known ways.
  • a known method is, for example, to use hydraulic piston/cylinder devices by means of which the pipe sections are driven in succession into the subterranean ground.
  • the disadvantage of this known method is, however, that the diameter and total length of the sequentially placed pipe sections that can be handled by it are limited.
  • pile-driving devices can be used.
  • a first type is a pile-driving device that strikes hammer blows on the pipe section with relatively high frequency.
  • the disadvantage of these pile-driving devices is that when they are used in certain types of ground with relatively high moisture, flow can occur. This is, of course, very undesirable, since it can cause subsidence in the subterranean ground above the pipe sections. Since in the case of the production of tunnels there is generally only a relatively shallow layer above the tunnel, such a flow phenomenon will directly give rise to subsidence.
  • pile-driving devices that can deliver blows with relatively low frequency, with high energy and at high speed.
  • shear occurs between the soil particles, instead of flow.
  • a number of pipe sections can be used in succession in the usual manner, which pipe sections are connected to each other.
  • This connection can be obtained, for example, by means of welding, or by means of mechanical connections.
  • bentonite can be added on the inside and/or the outside of said sections.
  • the non-round, slightly flattened shape of the pipe sections can be obtained in various ways.
  • two cylindrical pipe bodies fixed to each other by means of connecting plates can be used next to each other, which plates are fitted above and below the two pipe bodies situated next to each other.
  • a pipe section formed in this way possesses relatively great strength and rigidity, particularly also with regard to external loads in the vertical direction. These loads can be absorbed in a suitable manner by the two cylindrical pipes.
  • a flattened pipe section for use in the case of the method according to the invention can, however, also be obtained in another way.
  • a possible alternative that can be ' mentioned is the embodiment in which a pipe section comprising two facing cylindrical pipe halves or shell halves is used, which pipe halves are fixed to each other by means of connecting plates at their facing edges.
  • the connecting plates can be connected to each other by a vertical partition.
  • a further alternative is formed by a pipe section of reinforced or unreinforced concrete or plastic, which is provided with a head-end reinforcement on at least one end.
  • the invention also relates to a pipe section for use in the method described above.
  • Said pipe section according to the invention comprises a cross section whose height measurement is less than the width measurement.
  • Such a pipe section can be designed in the various ways described above.
  • any other flattened shape is possible, of course, in so far as it can withstand the loads that are exerted when the pipe section is being forced into the subterranean ground, and the loads that are exerted by the subterranean ground itself and by the installations above it, such as railways, roadways and the like.
  • the pipe section driven into the subterranean ground first preferably has a cutting edge in order to make the insertion work easier.
  • Fig. 1 shows an embankment 1, on which two traffic lanes, such as rail tracks or road lanes 2 are present.
  • a traffic tunnel has to be made in this embankment 1, and it must be made in such a way that the traffic making use of the traffic lanes 2 is not disrupted by the work. In other words, during the making of the tunnel it must always be ensured that no subsidence can occur in the embankment 1.
  • a first pipe section 3 is driven into the embankment 1 by means of an approximately horizontally placed pile-driving device 4.
  • This pile-driving device 4 is placed with a bedplate 5 on the subterranean ground 6 so sturdily that it can perform blows of sufficient magnitude on the pipe section 3.
  • Said pipe section 3 preferably has a front edge 7 which is in the form of a cutting edge.
  • a following pipe section 8 can be fixed to it, for example by welding.
  • the pile-driving device 4 is subsequently made to work in concert with said following pipe section 8, and so on, until the complete passage 9 opens out on the opposite sides in the embankment 1.
  • pipe sections 3, 8 of a flattened shape are therefore used, for example as shown in Figures 2 and 3.
  • the pipe section 3, 8 in cross section consists of two cylindrical pipes 10, 11, which are connected to each other by two connecting plates 12, 13.
  • Such a pipe section 3, 8, in view of the cylindrical pipes 10, 11, possesses a relatively high resistance to vertical loads.
  • a traffic lane can be provided in each of the pipes 10, 11.
  • the connecting plates 12, 13 can be fixed to each other, for example by means of welding, bolted connections and the like.
  • the pipes 10, 11 can also be fixed to each other.
  • FIG. 3 An alternative pipe section 3, 8, comprising two semi-cylindrical shell halves 14, 15, is shown in the embodiment of Figure 3. Said shell halves 14, 15 are connected to each other at their facing edges by connecting plates 12, 13. For the sake of strength, said connecting plates 12, 13 are connected to each other by a reinforcing partition 16. Traffic lanes can be provided on either side of said reinforcing partition 16.
  • Figure 4 shows an embodiment in which the pipe section 3, 8 is made of reinforced concrete and is of a rectangular cross-sectional shape with vertical walls 19 and horizontal walls 20.
  • the one head end of such a pipe section is provided with a head-end reinforcement in connection with the blows to be struck upon it by a pile-driving device; the other head end can be provided with a controllable cutting edge.
  • pile-driving device 4 is mentioned above in connection with making the passage 9 in the subterranean ground 6, other devices are also conceivable.
  • a hydraulic press device could be used.
  • said pile-driving device is preferably designed in such a way that it delivers blows with high energy and at high speed in combination with a low frequency. This prevents flowing of the material making up the embankment 1, which is important particularly in the case of types of subterranean ground 6 that are saturated with water.
  • a pile-driving device 4 which works with low frequency with higher energy blows causes shear in the particles in the subterranean ground 6, so that flowing of the subterranean ground 6 is avoided and subsidence can be prevented in a reliable manner.
