Definitions

  • EP-A-0 459 015 is a device on a concrete wall of a dam to be sealed od. Like. Hydraulic systems with at least one of these covering and sealing plastic film web known, which is anchored by a longitudinal metal profile on the concrete wall. Such a device is necessary for the dry refurbishment of an empty dam in order to bring the laid film webs smoothly against the retaining wall.
  • a longitudinal, raised box profile is anchored to the concrete wall, over which the plastic film web is laid over the surface of the concrete wall in one piece.
  • a hat-shaped clip rail is slipped over the film, over the box profile and screwed with this center.
  • the two U-shaped flanks of the clip rail move in the direction of the concrete wall and tighten the plastic film on the concrete wall.
  • the invention has for its object to develop a device with which a stronger tensioning over the entire surface of the concrete wall in the dry or wet laid films and an unchanged smooth concern of the sealing films on the concrete wall is made possible.
  • the metal profile is formed in cross-section as a closed hat profile, in the U-shaped interior of an air hose is arranged inflatable.
  • the metal profile is formed in cross-section as a double hat profile, wherein the two U-shaped profiles are arranged at a distance from each other and this thus formed web of the metal profile is anchored to the concrete wall.
  • each of the inflatable tube is arranged under both U-shaped profiles, namely between the concrete wall and the laid film web then each of the inflatable tube is arranged.
  • the hoses are inflated, so also moves the film in the associated U-shaped chambers with the wall of the respective tube, whereby the film is stretched. This is done on both sides of the anchoring of the profile.
  • a firm investment of the film along the concrete wall is the result. This result is achieved regardless of whether the rail in dry or wet, so below the water level of a dam is used.
  • the basic design of said device is also useful when a dam for rehabilitation is only partially emptied and the plastic films must be partially laid below the level in considerable depth. It is proposed to move the individual plastic film webs at the edges with a respective overlap of half a meter. Below the level, the hydraulic pressure is sufficient to seal the seam areas. In the dry but above the level, the seams in the region of the superimposed edge regions of the plastic film webs are mechanically sealed.
  • the defined rail with the inflatable tubes in the U-shaped chambers is also usable. Thus, the two superimposed film edges are pressed against the concrete wall with the air pressure in the two hoses. Of course, this rail can also be used here below the water level for attaching the film webs to the concrete wall to the application. There height differences in the concrete surface or voids are covered, including a mechanically strong connection of the film web with the concrete wall is advantageous.
  • the wall 1 'of the dam 1 or the dam wall as a whole is leaking and should be sealed with a coating on the water-covered side 2.
  • a carrier 4 is mechanically fastened via anchor 5 to the wall 1 '.
  • the carrier has a downwardly open U-shaped cross-section and is optionally accessible on the top.
  • On the support 4 is a defined width -. B. 5 m - and a defined length - z. B. reaching to the bottom of the dam length - the pack 6 'of the plastic film 6 held.
  • the film web 6 is wound around a weighting core mandrel 7, the core mandrel 7 being fixedly connected to the lower end of the film web 6.
  • the intermediate nonwoven fabric can be formed as a swellable nonwoven 8 'and / or as a drainage nonwoven 8 "The swelling nonwoven 8' swells on contact with moisture and assists in sealing the dam The drainage nonwoven 8" serves to check the tightness of the respective coating web, because if there is a leakage arises in the area of the railway, this water flows behind the film web to the bottom of the dam, there or is measured adjacent by a device. The hole can quickly be found and sealed again only in the area of this track.
  • the clamping profile consists of a metallic profile bar 11 which extends over a greater length usually perpendicular to the concrete wall 1 '.
  • the double hat profile consists of two U-shaped bent to the concrete wall 1 'toward open walls, which form the chambers 12, 13. Between the U-shaped walls of the profile extends a connecting web 14, by the screws 15, the profile 11 with the concrete wall 1 'anchor.
  • the concrete wall 1 ' is covered with the plastic film 6.
  • the swelling fleece 8' additionally seals the area of the profile bar 11 against the concrete wall on contact with liquid Chambers 12, 13 of the profiled bar 11 of the swellable nonwoven 8 'are in each case provided with a compressed PVC expansion hose 16, 17 between the swellable nonwoven 8' and the plastic film 6.
  • the tubes 16, 17 can also be upwardly surrounded by a further swellable nonwoven 8 be covered. It is also possible to form the respective hose through the swellable nonwoven by the overlapping swellable nonwoven layers include such inflatable air chambers. However, the condition is the airtightness of the nonwovens in this area.
  • the anchor sleeve 18 has for sealing with the film 6 on a sleeve flange 19, which is welded to the plastic film 6.
  • the tensioning of the film is then carried out by inflation of the two tubes 16 and 17 as shown in Fig. 4.
  • the inflated tubes expand, as far as in the chambers 12, 13 place, and take on their way the film 6 and put your hand on it.
  • this clamping state In order for this clamping state to be permanently fixed, the air in the hoses is ultimately replaced by an incompressible concrete suspension.
  • a plurality of plastic film webs 6 are drained across the width of the dam 1, which overlap at the edges in the seams 19.
  • Below the water level 3 is sufficient to seal this seam portion 19 of the hydraulic pressure of the water.
  • the seams 19 are to be sealed against each other.
  • the same metallic hat profile bar 11 as shown in FIGS. 3 and 4 are used.
  • the source webs 8 ' provide after contact with the dam moisture for additional sealing pressure.
  • geovlies 9 is still arranged according to FIG., Which filled with concrete for the protection of the film against environmental conditions against driftwood and the like. Provides.
