  • the clayey mass of matter may be clay, preferably recycled.
  • the source material may consist, for example, of bentonite powder, bentonite beads or bentonite pellets.
  • this object is achieved by a method for producing a self-sealing sealing material for sealing of floor surfaces, especially under water, such as soles and slopes of channels or the like, characterized in that clayey mass of material with the addition of at least one at Contact with water swelling source material is homogenized, the resulting material is compacted, formed into a plurality of three-dimensional bodies and the bodies thus formed are dried.
  • this object is achieved according to a further aspect by a method for sealing of floor surfaces, especially under water, such as soles and slopes of channels or the like, in which a clayey mass of earth is first prepared for homogenization and then applied to the bottom surface, characterized in that when homogenizing the clayey mass of matter at least one source material swelling upon contact with water is added, the resulting material is formed into a plurality of three-dimensional bodies, the bodies thus formed are applied to the bottom surface and at least one protective layer is applied to the applied bodies.
  • the prepared mass of material can be mixed with the source material on site, that is at the construction site, or in advance.
  • the protective layer also serves as a ballast layer.
  • the three-dimensional bodies may, for example, have cube shape, cuboid shape, disk shape, lens shape, barley grain shape or the like.
  • this object is achieved according to a further aspect of the invention by a method for sealing of floor surfaces, especially under water, such as soles and slopes of channels or the like, in which a clayey mass of material is processed for homogenization, characterized in that the processed mass of material is mixed with at least one swelling on contact with water source material and then applied to the bottom surface and at least one protective layer is applied thereto.
  • the protective layer also serves as a ballast layer.
  • the three-dimensional bodies may, for example, have cube shape, cuboid shape, disk shape, lens shape, barley grain shape or the like.
  • the present invention provides a device for applying bulk material, in particular self-sealing material according to claim 1, to a bottom surface under water, such as soles and slopes of channels or the like, comprising a chute, characterized in that a Schüttgutleit noise is provided which at least a roll-up or collapsible curtain of water-permeable, flexible material to form a bulk pass under the chute.
  • the method for producing a self-sealing sealing material may be provided that the resulting material is compressed and the plurality of is formed in three-dimensional bodies.
  • the three-dimensional bodies may, for example, have cube shape, cuboid shape, disk shape, lens shape, barley grain shape or the like.
  • the three-dimensional body can be dried by means of hot air or microwaves.
  • the three-dimensional bodies can be dried on a Rüttelrost.
  • the three-dimensional bodies are disk-shaped or platelet-shaped.
  • the three-dimensional body for installation in the embankment area are particularly suitable and can thus achieve high storage densities.
  • the at least one source material is bentonite powder, bentonite beads or bentonite pellets.
  • the three-dimensional bodies are disk-shaped or platelet-shaped.
  • the or at least one protective layer is a filter layer or a layer of water bricks.
  • a release layer preferably from Tonschnitzeln applied.
  • the bottom surface is a channel sole
  • the planum is prepared before applying the shaped body to the channel sole and a release layer, preferably made of clay chips, applied to the planum.
  • the or at least one protective layer is a filter layer or a layer of water bricks
  • a release layer preferably from clay chips, is applied directly to the layer of the mixture of prepared bulk material and at least one source material.
  • the bottom surface is a channel sole, prepared before application of the mixture of clayey mass of material and at least one source material, the planum and a release layer, preferably from Tonschnitzeln, is applied to the subgrade.
  • At least one curtain can be rolled onto a holding roller.
  • two spaced, parallel spreadable curtains are provided.
  • the invention is based on the surprising finding that a self-sealing seal or source seal is achieved by the use of source material, whereby a subsequent processing step can be omitted.
  • the surface seal has a self-healing effect in case of damage or subsidence.
  • FIG. 1 shows a disc-shaped body 10, which consists of clay 12 and thus mixed source material 14.
  • the source material 14 may for example consist of bentonite beads.
  • the body 10 may be dried and solid. Upon contact with water (not shown), the source material 14 begins to swell. In FIG. 1 is shown from top to bottom, as the source material 14 begins to swell and is getting bigger.
  • the bodies 10 may have different shapes depending on the location and condition of use.
  • the body 10 is made by homogenizing natural clay and adding source material so as to give an even distribution in the clay mass, followed by densification and special shaping.
  • the bodies are shaken by means of hot air or microwaves dried so far that sticking of the individual body 10 prevents and a low-deformation transport and storage is possible.
  • the drying process stops the swelling process of the source material.
  • the size of the body 10 depends on the conditions of the individual case, as small a body as possible is always desired in order to achieve the highest possible storage density of the body in a surface seal.
  • FIG. 2 shows a sectional view in the region of a channel bottom 16.
  • the planum 18 is made to avoid mixing with the upcoming sands of the channel bottom 16, the installation of a separation layer 20 made of clay chips.
  • body 10 applied in the form of a sealing layer 22.
  • a further separating layer 24 made of clay chips is applied in order to prevent mixing with the subsequent filter layers 26 and 28.
  • On the filter layer 28 is then applied a layer 30 of water bricks.
  • the filter layers 26 and 28 and the layer 30 simultaneously serve as ballast layers.
  • the bodies 10 When the bodies 10 are placed at the position to be sealed, which may be several thousand bodies per square meter depending on the size, the bodies 10 come into contact with water on their surface and become plastic.
  • the outer bentonite beads incorporated in the bodies 10 as the source material 14 begin to absorb water.
  • the bodies 10 increase in volume (see FIG. 3 ) and begin to self-seal the surface to be sealed. Due to the progressive water absorption The body 10, these are constantly plastic, so that the swelling process continues to progress.
  • the further layers 24, 26, 28 and 30 are applied as required.
  • the ballast layers cause a mechanical vertical pre-compaction of the sealing layer 22.
  • the lower region of the sealing layer 22 is capable of self-sealing these damages, since the latter still has source potential.
  • the swelling volume and the swelling rate can be adjusted,
  • the seal with bodies 10 and moldings made of clay to the requirements of the individual construction measure can be adjusted individually.
  • FIG. 4 shows the sealing situation in the area of a building or a sheet pile 32.
  • the sealing layer 22 is applied to the sheet pile 32 automatically.
  • a device 34 for applying the body 10 is shown as a sealing layer. Said device also serves to apply the separating and filtering layers.
  • Said device 34 has, in addition to a chute 36 for bulk material 38, a bulk material guide device made of a water-permeable and flexible material, in the present case chain mats 40 and 42.
  • the chain mats 40 and 42 extend vertically parallel to each other on two opposite sides of the device 34. More specifically, they extend at right angles to two oppositely disposed floats 44 and 46.
  • the chain mats are rollable on and secured to support rollers 48 and 50. By means of the retaining rollers 48, 50 they can be discharged more or less far down depending on the need and depth of the water 54.
  • the device 34 is still next to the point with built-bulk material 52 from the three-dimensional bodies described above, while in FIG. 6 is arranged above the built bulk 52.
