Definitions

  • the invention relates to a method for producing diaphragm walls, in which wall sections adjoining one another on the end face are concreted in succession and sealed by a vertically running joint tape, preferably provided with a horizontal shoulder in the area of the base plate connection, for which purpose a slot section is excavated in the length of the wall section to be produced, a formwork element extending over the diaphragm wall height, partially receiving the joint tape, which on its front side facing the slot section has projections for interlocking the individual wall sections, is arranged vertically at the end of the slot section, the slot section is provided with a reinforcement cage, concrete in Contractor procedure is introduced into the slot section, the subsequent slot section is excavated on the back of the formwork element and the formwork element after the partially embedded nated joint tape is lifted vertically.
  • the formwork element is pulled in the vertical direction, as is generally customary, for which purpose push-off cylinders act on the underside of a cross member which is fastened to the upper end of the formwork element projecting above the earth's surface.
  • the formwork element tapers towards its lower end in order to facilitate vertical pulling.
  • This vertical pulling which can possibly be made easier in a known manner by using formwork removal means such as greases or oils applied to the formwork element, poses a danger to the joint tape and its correct arrangement. This proves the long relative movement between the formwork element and the released joint tape when pulling vertically in the direction of extension of both parts as particularly disadvantageous.
  • the joint tape adheres locally to the formwork element, the joint tape can easily tear, especially since penetration of concrete slurry along the joint tape into the formwork element cannot always be prevented despite the transverse flange provided on the joint tape, which is supposed to seal against the formwork element.
  • the formwork elements can often no longer be pulled even after the above-mentioned auxiliary measures have been used after the concrete has more or less completely set, which is particularly the case with deep diaphragm walls is the case.
  • drawing may have to be started early, for example 3 to 4 hours after the start of the contractor procedure, which in the case of deep slots means a step-by-step drawing that begins before the relevant slot wall section is filled with concrete. It can be seen that pulling forces are already transferred to the joint tape before it is fixed in its upper areas in the more or less strongly set concrete.
  • Another source for improper joint tape sealing is another source for improper joint tape sealing.
  • formwork elements There two different formwork elements are provided, namely a box-shaped formwork element with a corresponding thickness in the contact area on the diaphragm walls, which largely makes it impossible for the concrete to pass to the rear of the formwork element, and a narrow formwork element in the form of a plate, the inclined walls of which slant towards one another from the longitudinal edges project and end at a distance from each other to accommodate the joint tape.
  • This formwork element which is thin on its sides opposite the walls of the slot, has a trapezoidal cross section which corresponds to the toothed recess to be formed in the band section to be produced. Accordingly, the formwork element is less wide than the slot and only delimits the slot in a central area.
  • the freshly filled concrete can indeed laterally flow past the formwork element, without the latter is flexed more in the longitudinal direction, but the diaphragm wall portion made receive frontally no smooth finish as is to be required for a single w andtransport slot wall without Erdei circuiting.
  • the invention has for its object to improve the above-mentioned method so that the risk of damage or displacement of the joint tape is largely eliminated from its intended sealing position, while a simple handy formwork element should be used at the same time.
  • This object is achieved in that the concrete introduced into the slot section for filling voids is also passed to the rear of the formwork element, that when or after the subsequent slot section is excavated, concrete adhering to the back of the formwork element is chiseled off and that the formwork element before it is lifted vertically from the manufactured wall section into the subsequent slot section into the side.
  • the formwork element does not have to be pulled after a short time, but can be done, for example, 24 to 48 hours after concreting, which is also advantageous from an organizational point of view.
  • the formwork element is still not lost and can be used again because on the one hand the back of the formwork element is chiseled free and therefore the adhesion to the concrete is limited to the front of the formwork element and on the other hand the formwork element is not pulled vertically but pushed off to the side, with the push-off force being targeted can be brought up to the height at which the formwork element has not yet detached.
  • Existing concrete bridges also tear between the front and the back of the formwork element, which do not cause any problems due to the comparatively small thickness of the formwork element.
  • the lateral pressing of the formwork element leads to a particularly short relative movement between the formwork element and the joint tape, so that the risk of tearing is low.
  • the joint tape is fixed in its sealing position by the already largely set concrete, even with deep diaphragm walls over the entire length of the joint tape.
  • the intended chiseling off of the concrete does not make the process much more difficult, since the access to the rear of the formwork element is provided in any case by lifting the subsequent slot section and since the adhering concrete can be chiseled off comparatively easily from the smooth back of the formwork element.
  • a chisel tool must also be used when excavating the subsequent slot section.
  • the concrete can be guided laterally around the formwork element to the rear, especially since breakouts can also be expected in the side walls of the excavated slot and a thin formwork element then offers no significant resistance to the flow around the concrete.
  • a formwork element which essentially closes off the diaphragm wall section and to be independent of any accidentalities caused by the respective geological formation, it makes sense to guide the concrete through the formwork element to the rear side thereof.
  • connections can be made at predetermined longitudinal distances between the front and the back of the formwork element, the connection cross-sections being dimensioned such that the concrete bridges penetrating the formwork element tear when the formwork element is pushed away from the side with a predetermined amount of force.
  • the invention also relates to a formwork element for carrying out the method according to the invention, consisting of an elongate plate with a flat rear side and with two stiffening members provided on the front side of the plate and running essentially over the entire length of the plate, which have transverse outer surfaces inclined to one another and between them Form a receptacle for the part of the joint tape to be embedded in the adjoining wall section.
  • Such a formwork element is, as stated, already known (US Pat. No. 3,464,665), even if it is only of training a toothed recess in the diaphragm wall section and not to limit the diaphragm wall section over its entire thickness.
  • Such a plate-shaped thin formwork element is particularly suitable for carrying out the method described above if its width is adapted to the diaphragm wall thickness.
  • this formwork element is designed such that the stiffening members also have outer surfaces which are inclined in the longitudinal direction. This measure is made possible by pressing the formwork element sideways before lifting it out. It not only leads to the fact that the adjoining wall sections are interlocked with one another in the vertical direction in addition to in the horizontal direction - which was previously only possible with concrete formwork elements remaining in the diaphragm wall (DE-OS 19 25 025) - in addition, in Interest in protecting the joint tape ensures that the formwork element must necessarily be pressed laterally to a predetermined extent, for example 20 cm, before it can be lifted vertically. A vertical pull in the usual way is thus excluded.
  • Lifting cylinders which can be extended and retracted can be integrated into the formwork element with longitudinal distances of, for example, 3 to 4 m and can be extended to an extent of, for example, 20 cm required for lateral pressing.
  • Figures 1 to 3 each show stages in the plan view (top) and in a vertical longitudinal section (bottom) with a shortened slot length in the manufacture of a subsequent slot wall section.
  • FIG. 4 to 7 show the first embodiment of the formwork element in a front view and a side view, in each case a central region of the formwork element being omitted, and in the two sections VI-VI and VII-VII made clear in FIG. 4.
  • Fig. 8 shows a perspective view, also with the omission of the central area, the end face of the wall section produced, the partially broken joint tape including the molded shoulder in the area of the lower sole plate is also shown.
  • Fig. 9 shows a perspective view of the joint between two adjoining vand sections with the joint tape.
  • Figures 10 to 13 show the second embodiment of the formwork element, again in front view, side view and in two characteristic sections indicated in Fig. 10.
  • Figures 1 to 3 illustrate the operation in the manufacture of a diaphragm wall section.
  • guide walls 1 and 2 are set in a known manner, which protrude, for example, approximately 1.5 m deep into the ground and determine the width of the slot to be excavated and thus the slot wall thickness.
  • the arrangement of the upper edge 3 of the guide walls 1 and 2 in alignment with the surface 4 of the soil 5 can be seen from the figures.
  • Fig. 1 is based on a concrete wall section 6 with a not yet drawn or raised formwork element 7.
  • a subsequent slot section 8 is excavated in a known manner.
  • the back of the formwork element is cleaned by lowering a tool 10 with chisels 11, which is already known for crushing the earth material to be excavated, into the slot section 8.
  • This tool 10 has been equipped with toothed strips 12 which chisel off the concrete 13 adhering to the rear of the formwork element 7.
  • the tool 10 is provided with an inclined run-up surface 14 which, in accordance with the force decomposition indicated by arrows, ensures that the toothed strips 12 are pressed against the smooth rear side of the formwork element 7.
  • the formwork element 7 After cleaning the back of the formwork element 7, this is pressed laterally into the slot section 8, as indicated in FIG. 2, which can be done in the manner described above and is not indicated in more detail.
  • the formwork element 7 detaches from the joint tape 15 previously received in it, which, as indicated, is approximately half embedded in the wall section 6 that has already been produced. After the lateral pressing, the formwork element 7 is lifted out of the slot section 8.
  • the mold member 7 is provided with a new joint tape 15 'and corresponding to FIG. 3 on the loading placed the re its concrete wall portion 6 facing away from the end of the slit section 8.
  • a reinforcement cage is arranged in the slot section 8 in a known manner, whereupon it is filled with concrete in the contractor process.
  • This concrete penetrates through the formwork element 7 or past its narrow longitudinal edges into the cavities 16 indicated in FIG. 3 on the back of the formwork element, as a result of which the concrete 13 shown in FIG. 1 and later demolished is formed.
  • the formwork element according to Figures 4 to 7 consists of an elongated plate 21, from the front of which two stiffening rails 22 protrude, which extend parallel to one another, form a slot-shaped receptacle 23 for the joint tape 15 and have end faces 24 which are inclined in the longitudinal direction.
  • the stiffening rails 22 are designed as a hollow profile with an inner leg 25 running perpendicular to the plate 21 and an inclined outer leg 26.

  • the stiffening rails 22 have also created a recess 34.
  • the joint tape 15 can be seen, the freely projecting section 36 was received in the slot-shaped receptacle 23 of the formwork element. Also shown in the area of the not shown sole plate on the joint tape 15 is the projection 37, which seals against water penetrating in the vertical direction.
  • FIG. 9 shows the wall section 32 with the adjoining wall section 38 and reveals the transverse toothing between the two wall sections and the position of the joint sealing tape 15, which is provided with a transverse flange 35 projecting on both sides.
  • the second embodiment of the formwork element shown in FIGS. 10 to 13 has a plate 41 which has on its front side two stiffening members 42 and 43 which extend in the longitudinal direction and are designed and arranged symmetrically to the longitudinal center plane.
  • the stiffening members 42 and 43 are releasably connected to the plate 41 by screws 44 (Figs. 12 & 12), so that the plate 41 can, if necessary, be exchanged for another plate of different widths.
