  • a connecting tube for connection to a Shaft or to a shaft opening in a shaft wall, especially in a caisson wall.
  • a single continuous Frost body can be generated or even several side by side arranged or spaced apart Frost body sections.
  • already existing wall means in Frame of the invention, in particular a wall with defined Surface, extending from the adjacent soil or soil different.
  • Already existing wall means in the frame the invention especially an artificially created wall, preferably a shaft wall, preferably a caisson wall.
  • the wall can also be a tunnel wall, in particular is formed by tubbings.
  • the icing medium by at least a part of the circumference of the Tube or at least along part of the circumference of the Connection opening in the wall running pipeline led and that is about this part of the tube circumference extending frost body is formed.
  • the pipeline runs the invention over the entire circumference of the tube or the connection opening. It is thus a circulating pipeline.
  • a Pipeline according to the invention only a supply line and only one drain line for the icing medium connected.
  • the pipelines according to the invention can Also known as icing loops.
  • the icing medium through one in direct contact with the one to be frozen Ground-standing pipeline is guided.
  • the pipeline is so with the proviso on the outer surface of the wall led that they are in contact with the surrounding soil that is to be frozen.
  • the pipeline in a provided in the outer surface of the wall and outwardly open channel arranged. It is located in Frame of the invention that anchors the pipe in the wall is, for example, with the help of several head bolts, which are connected to the pipeline and in particular to intervene in the concrete of the wall.
  • the at least a pipeline is arranged in the outer wall of a shaft, which shaft is connected to the tunnel via the tube becomes.
  • Outside wall here means the above, already existing wall. It is within the scope of the invention that this wall is a vertically arranged or substantially vertically disposed wall. at the above preferred embodiment is to a Querschlagan Kunststoff a tunnel to the Shaft or to the shaft structure. If this shaft Connected to a tunnel via the tube is after a preferred embodiment of the invention, at least a pipeline for the icing medium also in the tunnel wall intended. The pipeline is then expediently in the outer surface of the tubbings of the tunnel wall arranged. This at least one pipe in the outer surface the tunnel wall is to be preferred Embodiment in the sole area or in the ridge area of the to be made Tube.
  • the shaft may also be a trench wall pit act.
  • the invention is the method for a immediate connection between a tunnel and the Shaft used.
  • the tunnel leads directly into the shaft and in the area of Shaft wall to be created tunnel section forms the inventive Tube.
  • the tunnel becomes in this embodiment in particular to a passage through or Caisson connected.
  • Such a connection finds For example, also in station areas instead.
  • the soil icing is as nitrogen icing and / or carried out as a brine.
  • the soil icing is as nitrogen icing and / or carried out as a brine.
  • One Embodiment of the invention is characterized that in a part of the environment of the tube to be created at least one frost body with the help of at least one in the Ground introduced icing is generated. there So it is a ground icing after the State of the art, usually with icing lances is working.
  • Such a conventional one Soil icing may occur in the ridge area or in the sole area the tube to be created are performed. It but it should be emphasized that this conventional ground icing only as a supplementary measure to the ground icing invention is carried out.
  • the invention also provides a device for creating an underground tube, wherein at least one Wall is provided, in which a connection opening for a is introduced to the wall to be connected tube or introduced is, wherein in the outer surface of the wall at least one intended for the passage of an icing medium Pipeline runs, which pipeline the connection opening at least partially surrounds.
  • the pipe surrounds the connection opening via at least 50%, preferably over at least 60% and very preferred over at least 75% of the circumference of the connection opening.
  • the pipe the connection opening completely surrounds as a loop.
  • the pipeline is preferred in anchored to the wall, for example by means of headed bolts anchored in the concrete of the wall. It is within the scope of the invention that only one supply line to the pipeline and only one drain line for the icing medium connected. It is preferably about Inlet pipes and drain pipes with relatively low Diameter.
  • the invention is based on the finding that with the icing process according to the invention Stability, the life and thus the usability of the structures, i. the shafts and tunnels in comparison significantly improved to the known icing becomes.
  • the structures are only required by the Supply lines or drain lines for the Icing medium only minimally penetrated.
  • Pipelines or icing loops are not disturbed.
  • the figures illustrate a method of preparation an underground tube 1.
  • An icing medium becomes the Generation of this ground icing by at least one in an already existing wall 5 arranged pipe. 6 directed.
  • This pipeline 6 runs along the outer surface the wall 5.
  • the tube 1 in the protection of Bodenvereisung be made.
  • the pipe 6 extends over the entire Circumference of the tube 1 and the connection opening 7 in the Wall. Consequently, a frost body 2, 3, 4 on this entire circumference of the connection opening 7 is formed.
  • the pipeline 6 is in direct contact with the person to be frozen Ground. Appropriately, and in the embodiment closes the pipe 6 flush with the outer surface the wall 5 off. This is especially true in the enlarged Detail of Fig. 1 recognizable.
  • This section also shows that the pipe 6 is preferably in the wall 5 or anchored in the concrete of the wall 5 and although in the embodiment by means of head bolts. 8
  • the cross-connection is a tunnel 10 to a caisson 9 realized.
  • a pipeline 6 for the icing medium runs over the entire circumference of the connection opening 7 in the wall 5 of the caisson 9. This can be seen above all in FIG. 2.
  • the circulating Pipe 6 forms as it were an icing loop the connection opening 7. With this in the wall 5 circulating Pipe, a first frost body 2 is generated. In the bottom region of the tube 1, a second frost body 3 generated by ground icing.
  • piping 6 in the outer surface the tunnel wall 11 or on the outside of the Tubbing this tunnel wall 11 is arranged.
  • Such a pipeline 6 is expediently set in segments, because it is interrupted by the tubbing joints.
  • Such bottom icing in the bottom region of the tube 1 is especially necessary if the distance between tunnels 10 and caisson 9 is relatively large.
  • FIGS. 1 to 3 is otherwise a frost body 4 using the conventional soil freezing measures generated. These are individual icing holes in the ridge region of the tube 1 from the wall 5 brought in. This manufactured according to the prior art Frost body 4 merely supplements the inventively prepared Frost body 2 and 3.
  • the frost body 3 is replaced by additional pipes 6 in the tunnel wall 11 made. But that does not mean that for this Bodenvereisung an additional icing unit or an additional icing medium tank necessary is.
  • it is produced by an advance Supply bore from the caisson 9 to the tunnel 10th towards the icing medium from the caisson 9 to the pipeline 6 and transported to the pipes 6 in the tunnel 10. This feed hole is not in the figures been presented.
  • FIGS. 4 to 6 is a tunnel 10 directly connected to a caisson 9. It This is a particular of a tunneling machine passable caisson 9.
  • the tunnel 10 or the tunnel section in the region of the caisson 9 is in this embodiment at the same time to be created underground tube 1.
  • this pipe 6 is in the embodiment 4 to 6, only a single frost body 2 is frozen on the outer surface of the wall 5. in the Protection of this soil icing, the tunnel 10 at the Countersink 9 can be connected easily.
