Definitions

  • the invention relates to a seal for the execution of underground structures according to the preamble of claim 1.
  • the invention has for its object to form the seal of the generic type so that the soil masses can be compacted and drained within the seal.
  • the seal according to the invention is arranged in the form of a roof and is designed as an elastically deformable sealing cover gives the decisive advantage that such a sealing cover can adapt to the volume reduction of the soil masses and can also absorb the compressive forces of the groundwater on its outer skin in such a way that additional soil compaction is achieved in the enclosed drainage area.
  • the sealing walls of the sealing cover diverge from a central ridge line that lies on or below the surface run diagonally down to the waterproof floor.
  • This central ridge line which can be a working tunnel or the like, then represents, in cross-section, the upper tip of the cross-section triangle in question in the case of the roof-like, umbrella-like or the like.
  • the enclosed base can be subjected to a vacuum for the purpose of further solidification, whereby an additional compaction of the base in the enclosed drainage area is made possible.
  • Such an airtight sealing sleeve can then also be used as an additional security measure against air loss in compressed air drives in a low ground cover. In the event of unexpected leaks, it is possible in a simple manner to re-seal the sealing sleeve by re-pressing with the help of valve pipes.
  • the soil masses in the sealing shell of the construction site to be driven dry are sealed against the groundwater and the air, dewatered, compressed under the pressure of the groundwater on the outside of the sealing shell and / or stabilized by vacuum, so that a resilient, more stable and dry soil is obtained, which can be continuously developed in line with the progress of construction of the underground structure and can be mined in dry conditions from a protected position.
  • the sealing envelope is formed from sealing walls, the shape of which is adapted to the local conditions and which are formed by injecting a quantity of liquid on the basis of bentonite / filler / cement as a high-tension suspension jet with pressures of 300 to 600 bar into the soil mass to be sealed.
  • the tightness of the sealing sleeve is ensured in that the sealing walls are re-injected at rinsed-out, eroded points with injection agent at a pressure between 50 and 100 bar.
  • the construction pit enclosed by the sealing envelope can then be dewatered and kept dry for the actual construction process.
  • a swelling agent can be added to the injection agent.
  • underground tubes 1 are provided as underground structures, which are to be pre-built underground in dry conditions.
  • sealing walls 2 are provided, which are arranged in the form of a roof and thus form a sealing envelope 3, so that the sealing water 2 prevents the groundwater from the outside.
  • the soil masses 5 to be dismantled located inside or below the sealing shell 3 can be dewatered, for example, by means of vacuum deep wells, not shown, from the groundwater level 4 to a marl layer 8.
  • the external pressure of the groundwater in silt or fine sand 7 is caused by the sealing walls 2 of the sealing shell 3 caught.
  • the sealing walls 2 are integrated in the marl layer 8.
  • the sealing sleeve is formed between the sealing walls 2 or below the sealing walls 3 a drained and stabilized soil zone 5, within which tunnel tubes 1 can be driven.
  • the sealing sleeve 3 consists of roof-shaped sealing walls 2
  • an additional compaction effect is achieved by the pressure of the groundwater on the enclosed soil masses 5, namely in that the roof-shaped sealing walls 2 by adding a filler to the the base bentonite / cement mixture are formed as an elastically deformable sealing sleeve 3.
  • the elastic sealing walls 2 adapt to a volume reduction of the base 5 immediately without impairing the sealing function.
  • the roof of the sealing sleeve 3 is clearly drawn up towards the surface 13, ie that the sealing walls 2 of the sealing sleeve 3 diverging obliquely downwards from a central ridge line lying on the surface 13 into the water-impermeable floor 8 run.
  • the roof-shaped sealing walls 2 are clearly drawn down to the marl layer 8, the sealing walls 2 running from a ridge line below the surface 13 diverging obliquely down into the marl layer 8.
  • the volume of the sealing sleeve 3 is limited by the recessed sealing walls 2 and the area of action is narrowly restricted to the drainage zone 5.
  • This embodiment is particularly suitable for deep-lying construction pits in order to an internal vacuum drainage system, in addition to preventing the entry of groundwater from the outside, also preventing the entry of air from the outside and thus making the negative pressure particularly effective for the associated soil stabilization.
  • Fig. 3 shows an embodiment in which the sealing walls 2, starting from a ridge line, below the surface 13 serving cleats 11, are embedded deeply in the marl layer 8, so that the enclosed sealing sleeve 3 can graze in a very limited space.
  • the two underground tubes 1 are driven in the dry.
  • the degradation of the soil mass 5 from the marl layer 8 is facilitated in that it can be compacted and stabilized by additional injections using the soil fracturing method.
  • a Soilcrete sole 14 under the profiles of the underground tubes 1 serves to secure the hollow structure to the depth.
  • FIG. 4 shows floor plans of the elastic sealing wall 2, which are formed from sealing lamellae 15 and / or from intersecting columns 16.
