Definitions
- the object of the invention is a device for
- Devices for breaking out and expanding a tunneling section in a closed construction pit which comprise a knife sheath consisting of knife heads and adjoining knife tails.
- the entire knife sheath is held by support frames during the advance.
- the individual support frames dissipate their forces into the tunnel sole, while they support the individual knife heads or knife tails. If the knife sheath is closed in cross section, the supporting forces in the frame cancel each other out.
- breaking out the knives are driven individually or in groups and the support frames are subsequently lowered in order to follow the knife sheath in the breakout direction.
- a formwork device with formwork elements with formwork elements is also provided in the end region of the knife tails.
- the second device serves as inner formwork and is arranged with its outer side at a distance from the mountain or ground that corresponds to the inner diameter of the tunnel shell.
- the knife tails form the outer formwork.
- the expansion takes place, for example, by placing concrete in the space between the underside of the knife tails and the top of the formwork device. As the knife sheath advances, an intermediate space with a height corresponding to the thickness of the knife tails is created between the concrete layer and the mountain or floor.
- the space mentioned must be filled and pressed, for example with concrete or granulate, so that the floor does not penetrate into the space can break in.
- the concrete to be introduced into the intermediate space is supplied via lines, each of which opens into an outlet opening in the end region of the knife tail at its rear end edge.
- Such a known device is used when it comes to Losb ⁇ den.
- the tunnel opening is first pre-drilled and then concreted using a sliding formwork.
- sliding formwork can comprise supporting frames on which individual formwork slats are supported, the outer skin of the entire formwork device tapering slightly from front to back as seen in the feed direction in order to avoid constraints in the freshly concreted area along the individual formwork slats as they advance. If, for example, thickness tolerances and / or load deflections of the lamellae in the longitudinal direction caused unevenness in the concrete and thus constraints are exerted on the fresh concrete, this would lead to considerable damage without the conical taper.
- the formwork slats serve as inner formwork elements or as inner formwork slats, while the fixed floor serves as outer formwork.
- the concrete is pressed into the correspondingly sealed space at the foremost end of the sliding formwork, viewed in the direction of advance, the tunnel shell, which has already been concreted, used as a repository.
- the object is achieved by the features specified in claim 1.
- at least some of the end parts adjoining the cutter heads are used directly as inner formwork elements or inner formwork slats.
- a cavity is formed between the rock or ground and the top of the inner formwork slats. So that the cavity created above the inner formwork lamella, which is not supported, does not immediately collapse when the cutter heads are propelled, means for filling in self-hardening material or support material and binder are provided in the region of the transition between at least one cutter head and its inner formwork lamella.
- the inner formwork slats have means for filling in self-hardening material or support material and binding agent.
- the arrangement of the abovementioned means for every third or fourth inner formwork lamella has proven to be particularly advantageous.
- the materials mentioned are continuously introduced into the cavity as the cutter heads advance in order to achieve the required support effect.
- the cutter heads and the adjoining end parts are supported on a support frame of a walking frame.
- the device is preferably designed in such a way that all end parts which join the cutter heads are designed as internal formwork slats, in order thereby to achieve a uniform expansion over the tunnel wall.
- the cutter heads can be connected in one piece with the inner formwork lamellae or also be separated.
- a total length of the knife head and knife tail of usually around 10 to 15, it is advisable, at least with regard to the transport and the structure of the knife sheath, before it is introduced into the mountains, at least the knife heads and separate the inner formwork slats for transport and put them together on site. It may even be advisable to separate the inner formwork lamella and / or the cutter head at several points.
- a separation between the inner formwork lamella and the cutter head can take place, for example, perpendicular to the main plane thereof and can be designed in steps for constructional reasons. With certain cutter head lengths, it may also be necessary to design the cutter head in two or more parts.
- a particularly favorable connection point between the parts of the cutter head is arranged at the top of the inner formwork lamella.
- the lower part of the head can also be integrally formed with the inner formwork lamella ⁇ °.
- Knife head even during the advance, at least one insertable spacer or at least one insertable intermediate part is arranged between the parts of the cutter head.
- the top of the inner formwork slats is adjustable in their distance from the mountain or 35 floor. This is preferably achieved in that between each Inner formwork lamella and the support frame are each arranged in the main support frame height-adjustable and separately operable bearings. Due to the adjustability of the bearings, the inner formwork slats can move away from the concrete area individually or in groups.
- the inner formwork slat is either moved away due to the weight of the inner formwork slats when their bearings are loosened, or the inner formwork slat is pushed away from the freshly concreted area at the latest when constraints occur in the freshly concreted area, for example due to thickness tolerances.
- the proposed embodiment is at least intended to ensure that the inner formwork lamella does not press too hard against the fresh concrete and possibly damage it when advancing.
- the bearing between the cutter head and the support frame assigned to it should not be changed, so that the cutter head maintains its position when advancing and at a standstill.
- the height-adjustable coupling between the cutter head and the inner formwork lamella ensures that the inner formwork lamella can be easily moved away. But even with the one-piece design of the cutter head and inner formwork lamella, the
- the inner formwork lamella behaves like a self-supporting, clamped beam, with the clamping point representing the transition between the inner formwork lamella and the cutter head.
- a wedge bearing between the inner formwork slats and the support frame is a preferred embodiment of the actuatable bearing.
- the wedges lying on each support point at each support point are on the one hand with the inner formwork slats and on the other hand with the support frames firmly connected.
- the inner formwork slats from separate profiles, between which a bearing or a further bearing is arranged.
- the inner formwork slats then have an upper support profile facing the floor or the concreted shell and a lower box profile, which are connected via a shear-resistant coupling arranged between them.
- the shear-resistant coupling between the aforementioned profiles ensures that the profiles can move against each other perpendicular to the direction of the breakout, but are moved forward together in the direction of the breakout.
- the bearing provided between the support profile and the box profile can be designed hydraulically and / or pneumatically. If the upper support profile is to move away from the concreted area, this can be done by switching the hydraulic / pneumatic mounting from a rigid to a flexible mounting. It can also be arranged a gas buffer storage, which results in an elastic / resilient mounting of the upper support profile on the lower box section.
- the control of the storage can also be achieved with the help of a pressure relief valve that is arranged in the hydraulics or pneumatics. If the constraints become so great that a certain pressure between the support profile and the box profile is exceeded, the pressure relief valve automatically ensures that the bearing slackens or gives way.
- the means for filling in self-hardening material or support material and binding agent consist of at least one feed line, in particular a pipeline with filler neck, the outlet opening of which is arranged on the surface of the inner formwork lamella or on the back of the cutter head.
- the required support effect is achieved in that at least continuously through such a feed line during the advance of the cutter head
- Support material is pressed into the resulting cavity.
- the support material can consist of granules, while the self-hardening material, which also serves as the support material, consists of liquid concrete, for example. If required, a certain proportion of metal and / or plastic fibers can be added to the liquid concrete in order to increase the strength of the concrete.
- binders for example in the form of cement slurry or cement milk, into the granules. is pressed.
- the same filler neck through which the support material is also fed can be used for the binder.
- additional means for filling the binder which also consist of at least one feed line, in particular a pipe with a filler neck, the outlet opening of which is arranged on the top of the inner formwork lamella.
- a plurality of feed lines for the binders with outlet openings are arranged on the top of the inner formwork lamellae along their length and preferably distributed in the rear region or section thereof.
- the excavation area behind the cutter heads can initially be supported by the shielding plate, so that no rock or soil particles can fall into the cavity. This makes it possible, for example, to arrange the feed lines for the support material or the self-hardening material a little further away from the cutter head in a closed construction pit.
- the shielding plate used also results in the open design,
- all cutter heads can be moved forward by a maximum of about the length of the shielding plate without, for example, concrete being immediately pressed into the cavity. This creates a continuous cavity
- the shielding metal supply lines in the transition area between the cutter head and the inner formwork lamella are unnecessary. It is also conceivable that, for example, only the upper or some upper formwork slats contain the feed lines for the concrete 35 when the excavation pit is open. It is most favorable when arranging the shielding plate that it is connected to the top of the cutter head facing the floor, as a result of which a maximum cavity can be obtained. It is particularly advantageous if the shielding plate extends over the entire width of the cutter head. It may be desirable for narrow strips to remain free in the shielding sheets through which a non-interfering part of material falls into the cavity, but on the other hand the pressed-in concrete or the pressed-in binders penetrate beyond the shielding sheet into the surrounding soil.
- shielding plate is made of individual spaced apart
- Binder is mixed and care is taken that the spacing of the individual sheet metal parts is made larger or smaller, depending on the soil conditions.
- At least some cutter heads have strips or teeth on their surface facing the mountain or ground.
- the teeth tear open the floor, loosen it and the directly pressed-in self-hardening material or the support material can penetrate into the resulting cavities.
- the use of teeth in gravel is particularly advantageous or floating floors, but use with other floors is also possible.
- the gravel material falling into the cavity behind the cutter head can be immediately mixed into a favorable concrete mixture if, for example, cement slurry or similar binders are pressed in instead of liquid concrete.
- the hardening support material or the binder penetrate into the loosened soil and solidify it far beyond the surface of the cutter head.
- the entire gravel portion does not first have to be removed from the construction pit and other gravel mixed in the concrete has to be reintroduced, since the existing gravel can be used immediately to produce the required concrete.
- the teeth are advantageously spaced apart from one another.
- the formation of the teeth as longitudinal teeth extending in one piece over the length of the cutter head guarantees continuous scoring and thus a continuous surface design of the cavity, which may be necessary under certain static conditions. This also applies to the arrangement of the tips of the teeth in one plane.
- the teeth on a lower part of the cutter head can be arranged, the thickness or thickness (cross-sectional height) of which corresponds to the thickness or thickness of the subsequent inner formwork lamella.
- the teeth on the lower part of the cutter head can be removed individually or on a common lower part and are therefore arranged interchangeably. If a height adjustment of the teeth is desired, this can be done by arranging at least one insertable spacer or at least one insertable intermediate part. Depending on the change in the nature of the rock or soil, it may be advantageous to alternately replace a closed upper part with a toothed upper part.
- sheet metal extensions can be arranged at their ends facing the inner formwork lamella, which extend against a part of the inner formwork lamella in the direction of the breakout. If, for example, the floor is very loose or if excessive penetration of material into the cavity behind the cutter head is not desired, the arranged sheet metal extensions provide partial support for the excavation surface.

- FIG. 2a represents a longitudinal section through the device according to FIG. 1.
- the direction of advance or excavation is shown with an arrow.
- the cut is made through an inner formwork lamella 12 with a knife head 24.
- the cutter head 24 is formed in two parts and has a horizontal connection point 28 running at the top 26 of the inner formwork lamella 12.
- the cutter head 24 and the inner formwork lamella 12 are collectively referred to as a cutter 30 of the cutter cover.
- a number of knives 30 lying next to one another are shown distributed over the tunnel cross section 22 up to the sole.
- Each knife 30 is supported on four paired support frames 16, each pair of support frames 16 connected via frame feed presses 32 forming a walking frame 34.
- at least one frame feed press 32 is required, of which, depending on the circumstances, per walking frame
- the entire knife sheath is put together at the beginning of the tunnel cross section 22, which is prepared accordingly.
- the knives 30 are initially arranged with their ° knife tips 36 in the circumferential direction in one plane and are advanced individually or in groups during the advance.
- the tip 36 of each cutter head 24 penetrates the soil by a certain step. The fact that the surface 26 of each inner formwork lamella 0 12 relative to the corresponding top 38 of the
- Knife head 24 is set back, creates a cavity at the end 40 of the knife head 24 between the mountains or ground - hereinafter referred to as soil. So that the soil does not enter the knife 30 when it is being driven
- Filling opening 42 arranged.
- support material for example granules 44
- the fill opening is pressed continuously through the fill opening when the knife 30 is being driven into the resulting cavity.
- Granules 44 take place in the resulting cavity as long as the end region 46 of the inner formwork lamella 12 is still in contact with the already concreted part 10. It is therefore possible to move the entire knife sheath around in several steps
- the granulate 44 must first be mixed with binders, for example cement paste.
- binders for example cement paste.
- the binder can either be supplied through the filling opening 42 or through additional injection or filling openings 48.
- the cement paste is mixed so that the cement paste can mix well in the cavity
- cement paste preferably by the on the surface of the Inner formwork lamella is pressed in along the longitudinal direction of the filling openings 48 which are distributed.
- the cement paste it is advantageous, depending on the type of soil, that the cement paste not only spreads in the cavity, but also partially penetrates into the soil.
- the knives 30 can be advanced further.
- the problem may arise that constraints occur between the freshly concreted part (shell) 10 and the upper side 26 of the inner formwork lamella 12, which are caused by thickness tolerances in the inner formwork lamella 12 along its length and which affect the concrete as height tolerances transferred.
- the support of the inner formwork lamella 12 can be loosened by the wedge bearing, whereby the inner formwork lamella 12 moves away from the freshly concreted shell either by its own weight or at the latest when constraints occur. Moving away the inner formwork lamella 12 can be supported by a height-adjustable coupling of the inner formwork lamella 12 to the cutter head 24.
- the inner formwork lamella 12 will separate from the cutter head due to the elasticity of the material of the inner formwork lamella bend away. It is crucial that the cutter head 24 is not lowered during the advance. Therefore, as is also shown in FIG. 2a, there is no wedge bearing on the support frame 16, which is assigned to the cutter head 24. If the cutter head 24 is also lowered during the advance, the tunnel cross-section would taper correspondingly with increasing advance, which is not desirable.
- the inner formwork lamella 12 is then raised again to its original level, so that the top 26 of the inner formwork lamella 12 presses tightly against the previously concreted piece. This ensures that there is no step-like tapering with increasing tunneling distance even when finished.
- FIG. 2b shows a longitudinal section through an alternative device similar to that shown in FIG. 2a. Identical parts have identical reference numerals with regard to FIG. 2a.
- the device according to FIG. 2b differs from that according to FIG. 2a on the one hand in that instead of supporting material a solidifying material is immediately pressed into the resulting cavity and on the other hand in that the height adjustment of the inner formwork lamella is solved in a different way.
- the cutter head 24 has an insertable spacer as an intermediate part 29, with which the distance between the upper side of the cutter head 24 and that of the inner formwork lamella 56 has been increased compared to FIG. 2a.
- a solidifying material is - For example, concrete, pressed into the resulting cavity. Fresh concrete is pressed in continuously during the advance of each knife 50, so that the tunnel shell consists of pieces concreted together
- FIG. 3a shows a section through a spline bearing 14 along line 2-2 of the embodiment in Fig. 2a.
- the wedge bearing 14 consists of an upper wedge 64, which is fixedly connected to the inner formwork lamella 12, and a lower wedge 66, which is fixedly connected to the support frame 16.
- FIG. 3b shows a section corresponding to FIG. 3a along the line 3-3 of the device from FIG. 2b.
- a fixed bearing is provided between the support frame 16 and an inner formwork lamella 56.
- the inner formwork lamella 56 is composed of an upper one
- 35 two profiles 58, 60 is a hydraulic and / or Pneumatic storage 68 is provided, which, if necessary, namely when the knife 50 advances, allows the upper support profile 58 to move away from the concrete 54 to the lower box section 60, for example by switching to an additional gas buffer storage, which can be provided in the area of the storage 68 an elastic / resilient bearing is achieved.
- a hydraulic / pneumatic pressure relief valve can also be activated, so that when the pressure in the hydraulic / pneumatic bearing 68 increases, for example as a result of constraints, the pressure medium can escape via the pressure valve, so that the upper support profile 58 moves away from the concrete 54 can.
- the cutter head 70 has a special embodiment.
- the cutter head 70 usually consists of a profile which is closed in cross section, as indicated by a broken line 74 in FIG. 5. At this point it should be noted that it is necessary for the construction of a
- the Cutter head gives the most diverse design options.
- the cutter head can thus be formed in one piece and pass over to the inner formwork lamella without a separation or connection point.
- the cutter head can be connected to the inner formwork lamella via a connection point running perpendicular to its main plane, which can also be designed such that it can be adjusted in height.
- a connection running parallel to the main plane of the cutter head similar to that in FIG 2a at 28 connection may be advantageous, in which the cutter head consists of an upper part and a lower part, which is provided in one piece with the inner formwork lamella. 5
- the cutter head shown in FIGS. 4 and 5, however, has the special feature that its upper part 76 consists of strips or teeth 80 placed on an intermediate part 77.
- the intermediate part 77 is in turn on a lower part 78 of the
- Teeth 8 * 0 can be any, depending on the static and / or soil conditions. In this way, the tips of the teeth 80 can be arranged on one plane or can have a different height. The teeth 80 can in

- the effect of the shielding plate 84 is that a certain area of the ground can be supported or covered during the advance.
- the solidifying material which is pressed in under pressure, or the support material can penetrate into the soil between the single sheets 90 in order to specifically solidify certain areas.
- gravel floors for example, it can be possible, owing to the pressure that is injected, that a certain
- Portion of gravel penetrates into the cavity behind the cutter head 86 in order to mix and solidify with the pressed-in material. 5
- the shielding plate 84 can also be formed as a continuous plate covering the entire width of the inner formwork lamella 88. With such a configuration of the shielding plate 84, for example the fill opening 0 for the solidifying material can be arranged in the area of the covering of the shielding plate 84 in the inner formwork lamella 88. A fully covering shield 84 then also the knife 82 may be approximately the length of the shielding plate 84 are driven, without continuously consolidating material or immediately 5 1 support material is pressed in, since the soil through the
- Shielding plate 84 is fully supported and can not penetrate into the cavity behind the cutter head 86.
- the shielding plate 84 is then supported during the advance on the already at least partially solidified shell, so that a deflection of the shielding plate 84 is also avoided.
- a cavity can thus first be formed, which is only subsequently filled. Thereby, it is closed in the 0 as possible in the open excavation, to equalize the advancing of the shell and the filling of support material at least partially to perform ie separated in time.
- each of the inner formwork lamellas it is then not necessary for each of the inner formwork lamellas to have a filling opening for the material which is hardening or the support material.
