Definitions

  • the invention relates to a system and a method for distributing concrete, in particular for tunnel and gallery construction.
  • a number of branch lines are connected to a delivery line coming from a concrete pump via a distribution line, which lead into the formwork space at the end.
  • the branch lines first run outward in the radial direction in the tunnel and are then angled in the axial direction.
  • Each branch line can be opened and closed using a shut-off valve. After filling a formwork room, the concrete comes to rest in the respective branch line and there is a risk of setting, especially if no setting retarders are used for the concrete mixture. Even in the event of malfunctions, to prevent the concrete from setting in the distribution line and in branch lines, the entire line system must be disassembled, the concrete poured out and the pipes rinsed out.
  • a distribution system for concrete is known from US Pat. No. 3,556,116, in which a distribution line is connected to a delivery line and has a number of branch lines one behind the other at intervals.
  • a series connection of the branches is used here.
  • Plug the injection line by inserting a sealing plug.
  • Water pipe connections are also illustrated in order to rinse out the feed pipe in the reverse direction, but in this way a feed pipe filled with concrete cannot be cleaned sufficiently.
  • the object of the invention is to provide a system with which it is possible at any time to keep the distribution line including the branch lines free of setting concrete without having to dismantle the distribution line and / or the branch lines.
  • the drain line is preferably permanently connected to a concrete ejection device known per se via a shut-off valve. If there is a malfunction, which can have many causes, especially in tunnel construction, the delivery line is e.g. connected to the collecting container by means of a two-way slide valve and, after opening the shut-off valve in the drain line, a cleaning plug or cleaning ball is pressed into the line system by means of pressurized water, whereby the concrete column is pushed out of the distribution line and the subsequent part of the delivery line. All branch lines are filled with the plugs so that the line system can be completely cleared of concrete.
  • the concrete column can also be sucked out by switching the concrete pump to suction mode, but the cleaning plug or cleaning ball must always be used to remove any concrete residues.
  • the invention enables conventional concrete without Ab to use binding retarders, which previously seemed impossible, and even setting accelerators can be used, since the distribution system can be emptied when a concrete ring has been completed, and there is necessarily a pause in concreting during the subsequent implementation of an inner formwork ring.
  • the invention makes it possible to design the sealing plug in each branch line in such a way that, in its open position, it blocks the outgoing part of the distribution line, so that there is no concrete in the distribution line downstream of the respective branch. If all branches are operated one after the other, the concrete flow does not come to a standstill anywhere in the system, which is very advantageous for fast-setting concrete.
  • the method according to the invention comprises the measures according to claim 14.
  • the invention enables fully automatic operation, which also includes the emptying process.
  • the downtime of the concrete pump is continuously measured automatically and compared with a time limit set for the concrete quality, and when this limit value is reached the emptying process is automatically initiated while the concrete pump remains stopped. It is important that the emptying of the system can be effected at any concreting stage, so that the invention creates a high degree of safety, particularly when concreting tunnel tubes.
  • the distribution system according to FIG. 1 comprises a concrete mixing container 10, a double-acting concrete pump 12, the usual changeover valve 14, a delivery line 16 with schematically induce Clear telescopic tube extension 18 and an annular distribution line 30, which is arranged in a transverse plane of a tunnel and thus essentially at right angles to the longitudinal extent of the delivery line 16 and has a number of branching points 32 arranged at circumferential intervals and which via a pipe loop 39, 40 to the delivery line 16 connected.
  • the distribution line 30 lies on a diameter which is larger than the diameter of an inner ring formwork 22 and runs closely adjacent to an end formwork 24 which closes a formwork space between an outer ring formwork 20 and the inner ring formwork 22 to the front.
  • the distribution line 30 thus lies in the annular gap 42 between the outer and inner ring formwork and, thanks to the close proximity to the end formwork 24, short, straight branch lines 34 at each branch point 32, which penetrate the end formwork 24, are sufficient.
  • the delivery line 16 is extended in the interior of the tunnel beyond the level of the front formwork 24.
  • a pipe bend 39 extends around the front edge of a pressure ring 76 and a subsequent connecting pipe 40 bridges the width of an inner formwork segment including the width of the pressure ring, as can be seen in particular from FIG. 2 results. This pipe loop is necessary in order to be able to assemble the next inner formwork ring 22.
  • a shut-off device 36 is provided with which the branch line 34 can be shut off.
  • the distribution line 30 extends along a circumferential angle of more than 270 ° and at its end is connected via a pipe loop 44, 46, which corresponds to the pipe loop 39, 40 and serves the same purpose, an emptying line 48 which extends parallel to the delivery line 16 and runs back into the tunnel.
  • the drain line 48 is connected via a valve 50 to a concrete pushing device 52, which has a holding device 54 for a hose has plug 55.
  • a pressurized water pump 56 is connected to the holding device 54.
  • a circulation line 58 branches off from the drain line 48 and can be shut off by a valve 51 and leads back into the mixing container 10.
  • the shut-off valve 36 has three quick couplings 38, by means of which it is connected to the incoming part 30a of the distribution line 30, the outgoing part 30b and the short straight branch line 34.
  • a plug 66 in the form of a piston is slidably mounted, which has a curved front surface 70, which for a constant transition of the concrete flow from the incoming part 30a of the distribution line 30 with deflection by 90 ° in the branch line 34 provides.
  • This curved end face 70 of the sealing plug 66 also ensures that the sealing plug 66 is longer in the area of the outgoing part 30b of the distribution line 30 and thus in the area shown in FIG.
  • the sealing plug 66 is connected at the rear to a drive cylinder 69, which moves it forward into a closed position in which the sealing plug 66 comes out of the branch line 34 penetrates into the formwork space beyond its mouth 68 and thereby completely fills the branch line 34.
  • the plug 66 has a transverse channel 74 which, in the closed position of the plug 66, connects the incoming part 30a to the outgoing part 30b of the distribution line 30.
  • the ring line 30 is fastened on both sides of each shut-off device 36 to the front formwork 24 by means of holders 25.
  • the distribution line 30 is then filled with concrete, since all the shut-off elements 36 located in between are in the open position.
  • the other shut-off elements 36 can now be opened one after the other in any order in order to complete a concrete ring 26.
  • the front formwork 24 which is connected to the outer formwork 20, moves.
  • the front formwork 24 is pushed partly by the pressure of the pressed-in concrete and partly pulled by a cylinder 28 which is fastened to a frame 29 of the driving head.
  • the front formwork 24 has arrived at the front end of an inner formwork ring 22, the concrete ring 26 is finished (FIG. 3).
  • the pressure ring 76 is pulled forward by means of cylinder 78 and a new inner formwork ring 22 is mounted (FIG. 4) which is then pressed against the inner formwork by means of the pressure ring 76.
  • the concreting process then continues in order to produce a new concrete ring in the area of the annular gap 42.
  • valve 51 can first be opened in order to keep the concrete in motion throughout the pipeline system by the concrete pump 12 running slowly.
  • the plugs 66 are all in their closed positions.
  • the concrete pump 12 is switched off, a slide 80 in the delivery line is closed and a slide 81 in an outlet line connected to the delivery line is opened, after which the pressurized water pump 56 is started, which removes the cleaning plug 55 inserted into the holding device 54 through the emptying line 48, the annular distribution line 30 and the part of the delivery line 16 lying in front of the slide 80, the concrete located in this line system being pushed out in a collecting container 82. Since the cross-sections of all the lines 16, 30, 48 including the valve passages differ only slightly from one another at most, the elastically designed cleaning plug 55 ensures almost complete emptying of the line system, the pressurized water flushing out any concrete residues.
  • FIG. 7 to 12 a modification of the distribution system is shown, which differs from the one described above only in that the distribution line 130 does not run directly adjacent to the plane A of the face formwork 24 but at a distance therefrom in a plane B, so that the distribution line 130 in front of the pressure ring 76 runs.
  • the distribution line 130 is interrupted for each branch point 32.
  • the two interruption ends are connected to one another by means of a pipe loop 84, which extends into the annular gap 42 between the two ring formworks 20, 22 approximately parallel to the tunnel axis up to near the end formwork 24 and in whose apex the shut-off device 36 is arranged.
  • a pipe loop 84 which extends into the annular gap 42 between the two ring formworks 20, 22 approximately parallel to the tunnel axis up to near the end formwork 24 and in whose apex the shut-off device 36 is arranged.
  • 36 spaces are exposed in the annular gap 42 between two shut-off valves, which for example for other purposes as an additional support for the
  • each pipe loop consists of two parallel pipes 84, which extend in the longitudinal direction of the tunnel, and two pipe bends 86, which are connected to the housing of the shut-off device 36 by means of the quick couplings 38.
  • the distribution system according to FIG. 13 to 18 consists of a distribution line 30, which has no axial pipe loops, because it is arranged in front of the pressure ring 76 and attached to it.
  • the two lower ends of the distribution line 30 are connected to one another by a connecting tube, so that there is a circumferentially closed ring line, at the ends of which a shut-off device 90 and 91 is provided.
  • Another shut-off element 93 closes the end of the drain line 48.
  • the displacement axis 162 (FIG. 18) of the sealing plug 166 does not cross the ring axis of the distribution line 30 here, but is offset radially outward by an amount that is equal to the sum of the radii of the branch line 34 and the distribution line 30.
  • the inner circumferences of both lines touch each other.
  • the pipe section 160 for receiving the sealing plug 166 has an opening 92 through which the branch line 34 communicates with the distribution line 30.
  • the closure piece 166 has no through channel corresponding to the channel 74 in the previously described embodiments.
  • the shut-off device 36 has a flat slide 88 which is displaceable in a slot 94 in the valve housing and is actuated by a drive cylinder 96.
  • the plane of displacement of the flat slide 88 almost touches the pipe section 160, forms the Ver with a radial plane passing through the axis 162 of this pipe section 160 partial line 30 an angle of about 30 ° and closes the outgoing part of the distribution line 30 in its closed position.
  • the flat slide valves 88 are preferably located in both ring halves of the distribution line 30 above the respective branches 32 because the distribution system according to FIG. 13 to 18 allows concrete to be fed from below into both halves of the distribution line 30 without having to fill the remaining part of the distribution line 30 with concrete.
  • the valves 90, 91 are opened in order to operate the branch line 34 at the bottom right.
  • the flat slide 88 are in the closed position. It is then possible to switch to the next higher branch line 34 by closing the valves 90, 91 and opening the flat slide 88 of the valve arranged at the bottom left. After a formwork space is filled with concrete (FIG.
  • the pressure ring 76 with the distribution line 30 and face formwork 24 is pulled forward by one formwork width by actuating the cylinder 78, and since a segmental formwork is used in this exemplary embodiment, a new ring made of segment segments 98 is installed and pressed against the remaining tubbing formwork by means of the pressure ring 76 (FIG. 15).
  • the cylinder 28 is actuated, which, like the cylinder 78, is supported on a trailing part 100 of the cutting machine in order to advance the outer formwork 20 by a segment width.
  • the concrete is then poured into the formwork space 27 as described. The result is shown in FIG. 16.
  • the two valves 90, 91 are closed and the valve 93 is opened after the valve 80 in the delivery line 16 has been closed and the valve 81 in the outlet pipe has been opened. Then, after the pressure water pump 56 has started, the cleaning ball 55 can be pressed through the entire line system in the manner already described, in order to insert the concrete column into the Slide out container 82. It is understood that the plugs 166 are in the closed position and the flat slide 88 are in the open position during the emptying of the system. The connecting line between the two valves 90, 91 can also subsequently be flushed when the two flat slides 88 of the two lowest shut-off elements 136 are closed.
  • FIGS. 19 and 20 illustrate an annular distribution line 30 with shut-off device 36.
  • the distribution line 30 lies within an inner ring formwork 22 and the branch lines 34 extend in the same radial plane in which the distribution line 30 lies radially outwards and into the inner ring formwork 22.
  • the pipe loops 39, 40 are omitted. Otherwise, the system does not differ in principle.
  • FIG. 21 shows a distribution system which, with regard to the annular distribution line 30 and the shut-off elements 136 of the embodiment according to FIG. 13 corresponds. However, the difference is that the connecting line with the valves between the two lower ends of the distribution line 30 is omitted. This is followed by parallel pipes 17, 19 running in the longitudinal direction, which are connected to the common delivery line 16 by means of a two-way valve 102 and optionally receive concrete from the concrete pump 12. In this simple version, too, both halves of the annular distribution line 30 can be fed from below.
  • the two pipes 17, 19 are detached from the distribution line 30 by means of the quick couplings 38 and two hoses 104, 106 are coupled, one of which leads into the collecting container 82 and the other of which is connected to the emptying line 48.
  • This embodiment is simpler thanks to the lack of valves, but requires manual intervention to empty the line system.
