Definitions

  • the invention relates to a shield tail for a Schildvortriebs adopted with a number of open to a tail shield, feedable with filling grouting lines for pressing an annular gap with the filler, which are supplied with additive feedable overhead lines, which open in an end portion of the grouting lines in the grouting lines.
  • Such a shield tail for a shield propulsion device is known from DE 100 40 777 A1.
  • the previously known shield tail has a number of open to a tail shield, feedable with filler grouting lines for pressing an annular gap with the filler.
  • feed additive feed lines are available with additives, which open into the injection lines in one end section of the injection lines.
  • the filler material and the additive or additives are mixed in a mixing chamber, before the mixture exits through a relatively small, opening into the outer region of the shield tail outlet opening to the outside.
  • a disadvantage of the previously known shield tail is that, in particular during prolonged shutdowns, the mixed material hardens in the mixing chamber and can be removed from it only with great difficulty.
  • a shield tail is known, in which open to a shield tail end Verpress Gustaven are present, which are formed from steel castings and welded in a shield tail coat.
  • the grouting lines can be fed with mortar as filling material for an annular gap.
  • closable rinsing openings are provided for cleaning the injection lines with lids, can be removed on the at a work interruption in the grouting lines existing mortar before it hardens and closes the grouting lines.
  • a disadvantage of this device is in addition to the relatively cumbersome and laborious cleaning the need for a work stoppage and use To begin relatively quickly with cleaning from relatively quickly solidifying filler material to avoid closure of the injection lines.
  • the invention has for its object to provide a shield tail of the type mentioned, in which a reliable entry of the solidification accelerating additives is created in the filler.
  • the aggregate lines end having a trained with a valve assembly line head and that moreover the line head valve assembly having a valve body with outlet openings and at least one outlet openings covering ring sleeve made of an elastic material.
  • the sealing units each have at least one surrounding the associated additive medium line seal, a clamping nut and at least one cooperating with the clamping nut, the associated Zuschlagstofftechnisch enclosing clamping ring, wherein when tightening the clamping nut, the associated Zuglertechnisch fixable and at a certain position of the clamping nut the assigned additional agent line is displaceable in the longitudinal direction.
  • FIG. 1 shows a sectional view of an exemplary embodiment of a shield tail 1 according to the invention of a shield propulsion device (not shown in FIG. 1).
  • the shield tail 1 according to the embodiment of FIG. 1 has a shield tail coat 2, in which a number of straight in an end region Verpress effet 3 are integrated.
  • the grouting lines 3 open in the region of a shield tail end 4 formed with a shield tail seal according to the single-lip type when the shield driving device is used in an annular gap 7 formed between segments 5 and pending soil 6.
  • filling material such as mortar for filling the annular gap 7 can be fed.
  • an additive medium line 8 is made of a rigid, However, to some extent still bendable material introduced which can be fed with a filler to be added to the filler such as in particular a solidification accelerator.
  • Each additional supply line 8 extends through an inserting adapter 9 which is formed integrally with the shielding-tailed shell 2 in the illustrated exemplary embodiment and which receives a sealing unit 10 surrounding the respective additional-supply line 8. With the sealing units 10, the additive medium lines 8 can be fixed in a specific position.
  • Each with an insertion section 11 at an angle to the respective Verpress effet 3 aligned aggregate line 8 is in a from the Einstockedadapter 9 to the tail end 4 extending end portion 12 of the associated Verpresstechnisch 3 after a bend with a prepared by turning and corresponding alignment parallel section 13 is substantially parallel and disposed approximately centrally within the end portion 12 of the respective Verpress effet 3.
  • each aggregate supply line 8 is equipped with a valve assembly having a line head 14 through which the additive is inserted into the respective grouting line 3.
  • the additive mixes with the filler only immediately before entry of the filler into the annular gap 7, so that the effects desired by the additive, such as accelerated solidification of mortar only within of the annular gap 7 and not already within the grouting lines 3 further in front of the shield tail 4 with the risk of unwanted and only extremely complicated to be removed again solidification in the grouting lines 3 occur.
  • FIG. 2 shows in a sectional view a further exemplary embodiment of a shield tail 1 according to the invention, which has a number of injection lines 3 which run angled in front of the end section 12 in the flow direction of the filling material and open into the annular gap 7 explained with reference to the embodiment according to FIG.
  • the additive medium lines 8 terminate near the shield tail 4 formed in the embodiment of FIG. 2 with a brush-type seal.
  • the aggregate lines 8 in this exemplary embodiment extend between the filling material which can be fed into the injection lines 3 in the flow direction a last bend 15 arranged Ein 1500adapter 9 with a parallel portion 13 and the tail end 4 substantially parallel and approximately centrally to the respective Verpresstechnisch 3, so that from the in the illustration of FIG. 2 directly in the region of the tail end 4 arranged in the line head 14 leaking additive is relatively homogeneously miscible with flowing in the injection lines 3 filling material.
  • FIG. 3 shows in a sectional view a further embodiment of a shield tail 1 according to the invention with a comparison with the arrangements of FIG. 1 and FIG. 2 staggered additional supply line 8.
  • the line head 14 in the end portion 12 of the injection line. 3 arranged with a certain distance from the tail end 4, so that from the head 14 in the flow of filling material leaking additive still within the remaining portion of the end portion 12 to to the shield tail 4 mixes with the filler and caused by the additive effects already occur before the mixture enters the annular gap 7. Due to the specific arrangement of the line head 14 is thus a relatively accurate adjustment of the properties of the mixture of the filler and the admixed additive at the exit from the shield tail 4 achievable.
  • an end piece 16 of an additive supply line 8 is ejected.
  • the end piece 16 was cut in the direction of flow of the additive upstream of the sealing unit 10 and re-fed with a line head 14 stocked aggregate 8 in the direction of the tail end 4 with sufficiently relaxed sealing unit 10 brought into the position shown in Fig. 4.
  • Upon further advancement of the additive supply line 8 in the direction of the tail end 4 of the tail 16 is finally ejected into the annular gap 7.
  • blockages of injection lines 3 occurring in the region of the tail of the shield 4 can be eliminated in this way even in the region of the tail of the shield 4 by ejecting the stopper 16 which engages with a stop while entraining the stopper.
  • FIG. 5 shows a sectional view of an exemplary embodiment of a sealing unit 10 for the sealed fixing of an additive medium line 8 and an exemplary embodiment of a line head 14 of an additive medium line 8.
  • the sealing unit 10 has seals as round cord seals 17, which are inserted into corresponding recesses of the Ein 2015adapters 9 and surrounding the aggregate supply line 8 sealingly. Furthermore, the Sealing unit 10 equipped with a clamping nut 18 and cooperating with the clamping nut 18 clamping rings 19.
  • the clamping nut 18 can be screwed onto a thread formed on the Ein 1500adapter 9, wherein when tightening the clamping nut 18, the clamping rings 19 are pressed against the aggregate line 8 while fixing the same.
  • the contact pressure of the clamping rings 19 is reduced, so that at a certain position of the clamping nut 18, the additive medium line 8 is displaced in the longitudinal direction.
  • the line head 14 has a cylindrical valve body 20 which is attached via a latching connection 21 at the end of the parallel section 13 of the additive medium line 8 facing the tail end 4.
  • the valve body 20 has a valve arrangement with a number of introduced into the wall outlet openings 22 which are covered by annular sleeves 23 made of an elastic material.
  • the covering the outlet openings 22 seat each annular collar 23 is secured by circumferentially on the outside of the valve body 20 projecting annular shoulders 24.
  • the line head 14 has an end-side end piece 25, with which the direction away from the parallel section 13 end of the valve body 20 is closed.
  • the line head 14 of FIG. 5 exits from a certain pressure within the aggregate line 8 through the outlet openings 22 additive, while the annular collars 23 prevent the ingress of filler in the aggregate 8.
  • FIG. 6 shows in a sectional view a development of a line head 14 of a supplemental line 8 according to FIG. 5.
  • a number of, for example, are in the valve body 20 and in the end piece 25 annular depressions 26 are introduced, which are in the case of solidification of the mixture of filler and additive in the injection line 3 with a trained in the injection line 3 plug in engagement.
