Definitions
- the invention relates to a method for constructing a seal protection layer in a landfill site for sludge industrial and mining waste and a geotextile protection tube mat for performing the method.
- the mechanical damage can result from driving on and passing the sealing level.
- the application of a UV and thermal insulation layer of sand, earth or mixtures containing concrete is possible, but in view of the large di- the mud ponds and their enclosing embankment are big machines for transporting and distributing the masses.
- the lower sealing layer is often damaged, so that it can also lead to leaks when using multi-layer waterproofing membranes, resulting in a significant environmental hazard.
- GCL mat Gelar Clay Liner
- the object of the present invention is therefore to provide a method for establishing a seal protection layer in a landfill site for sludge industrial and mining waste, by which the actual sealing level is protected from heat and UV radiation and mechanical damage.
- a protective tube mat made of a water-permeable geotextile fabric leads to a significant reduction in weight during transport, in comparison to the introduction of large quantities of sand or concrete for covering the sealing layer.
- the geotextile protective tube mats can be delivered rolled up and are then laid out on the floor of the landfill site and on the embankments. For laying, it is not necessary to drive on the waterproofing membranes with heavy working equipment, so that mechanical damage to the waterproofing membranes is avoided.
- the geotextile, from which the protective tube mats are formed optically so dense that there is already in the unfilled state, a substantial protection against UV radiation for the underlying geomembranes.
- the geotextile protective tube mats can thus be designed at an early stage and can be subsequently aligned in their position to each other, being given already without filling a good UV protection for the geomembranes.
- the tube tubes formed therein are then individually filled with an aqueous suspension.
- parallel connection lines are present on the protective tube mats which a lower and upper layer of the fabric are connected to each other, in particular, are woven together, with each forming a tube between the connecting lines.
- These tube tubes are separated from each other, that is, the layers are so closely connected that, although water, but no sludge can flow into an adjacent tube.
- the tube tubes are also each individually closed at its end, z. B. by sewing the two layers. At one end, the tube can initially remain open and serve as a filling opening. It is also possible to introduce a separate filling opening on the upwardly facing position of the protective tube mat.
- the tube is then filled via the filling opening so that a rib-shaped structure is formed, as with an air mattress, but with chambers separated from one another.
- the forming on the tube fins are in the bottom area of the landfill in any orientation, and preferably so that the maximum production length for the tubular mat of about 150m is optimally utilized and laying with as little seam or overlap sites as possible.
- the orientation is such that the tube tubes or the ribs formed later by filling run in the direction of fall. They can also be arranged slightly obliquely, but only at an acute angle, in order to preserve the flowability of the filled-in sludge during the installation of the protective layer.
- the filling can be done with a water-sand mixture or with concrete.
- the water can escape quickly through the geotextile.
- a dehydration and thus an automatic compression of the filled substance within the tube are already carried out during the filling process.
- Essential here is the use of mats with separate, tubular subdivisions, because due to the relatively small diameter of a single tube in relation to the mat overall, the water has to cover only small ways, until it gets to the geotextile outer skin and there drain or evaporate ,
- the shape of the tube also means that the filled strand is almost completely surrounded by geotextile tissue, ie in particular also at the side edges at which the connecting lines are formed.
- the waste sludge to be stored in the landfill site itself can also be used to complete the protective hose mat.
- the material and transport costs account for it and also because the reduction of capacity due to the up to 30 cm high protective layer is eliminated.
- the use of the waste sludge for filling is completely harmless, since the tightness with respect to the ground is in any case effected exclusively by the base sealing layers, which comprises, for example, a plastic sealing strip.
- the water-permeable but opaque geotextile fabric of the protective tube mat prevents sediment from being blown away by the influence of wind after the mud has dried out, potentially contaminating toxic substances. Since the water contained in the sludge can escape quickly through the geotextile, according to the invention, a dehydration and thus an automatic compression of the filled substance within the tube takes place already during the filling.
- the transport of the filler without vehicles is possible by a pumpable suspension is introduced via a hose system in the tube tubes.
- the hose tubes have one or more filling openings, depending on their length.
- the filling openings are arranged in particular in a central area, so that a flow direction on both sides and thus a uniform filling result. It is also possible to provide additional filling openings in the respective end areas in the floor protection tube mats, in order to fill the tube tubes quickly.
- the filling opening is preferably provided at the top of the protective hose mat to be arranged so that here either a hose nozzle is introduced and the sludge from there runs down in the tube or that the tube is pushed through the filling opening in the tube and then is gradually withdrawn with increasing filling level.
- a preferred application provides for the protective tube mat to be laid on a bentonite-containing base sealing layer.
- water comes out, which leads to the swelling of the bentonite.
- this also provides a ballast, which prevents rising of the geomembranes and / or uneven swelling of bentonite webs.
- a geotextile suitable for carrying out the method is given in claim 9 and comprises at least one lower and one upper layer, which are interconnected by at least two parallel connecting lines, so that at least one tubular tube is formed between the connecting lines.
- a subdivision into several tube tubes takes place. Since the tube tubes, which are initially lying flat, rise up in rib form during filling, a subdivision into a plurality of individual tube tubes serves, in particular, to reduce the height of the completely filled protective tube mat.
- a further preferred embodiment of a geotextile protective tube mat provides an additional UV protective layer, which is formed from a synthetic fiber fleece and is placed on the outwardly facing sun-exposed surface of the protective tube mat.
- This UV protective layer is at least selectively connected to the multi-layered protective mat, so that the installation of the protective tube mat and its UV protective layer can be done in a single operation.
- the UV protection layer protects the sun-exposed areas, especially at the slope protection tube mats.
- a UV protective layer is generally not required, provided that the commissioning and filling of the landfill site takes place shortly after laying.
- Fig. 1 is a protective tube mat in a sectional perspective view
- Fig. 2 is a protective tube mat in plan view
- Fig. 3 is an empty landfill corners in a perspective view
- Fig. 5 is a landfill corners with some designed protective hose mats, in a perspective view
- FIG. 1 shows a protective tube mat 10 required for carrying out the method according to the invention in a sectioned perspective view.
- This consists of a lower layer 17 and an upper layer 18, which are each formed as geotextile, wherein the layers 17, 18 are connected to each other along parallel connecting lines 15, in particular interwoven with each other.
- Another connecting line 15 is in each case at the outer edges. Additional fasteners, such as zippers, may be provided at the edges to allow adjoining tubular protective mats to overlap each other without overlap.
- Filling openings 13 serve to fill the tube tubes 12 formed between the adjacent connecting lines 11 and between the interconnected layers 17, 18.
- an additional UV protective layer 19 is applied. This is connected to the underlying fabric layer of the upper layer 18 along the connecting lines 1 1, 15.
- Figure 2 shows the protective tube mat 10 in the unfilled state from above.
- the width, and thus the size and number of connecting lines 1 1 and tube 12, is limited production technology and is about 5 m. In the longitudinal direction, however, very long track lengths of up to more than 100 m are possible.
- This width is for example divided so that the tube stirring 12 in the filled state have a height of about 30 cm - 40 cm. Since there is no strong internal pressure during the filling, which takes place solely with hydrostatic pressure, an elliptical cross-section results for each tube after filling, the z. B. has a width of about 60 cm at the said height of 30cm - 40 cm. Together with the surface required for weaving, welding, gluing or sewing along the connecting lines 11, 15, the width per tubular tube 12 in the unfilled state is approximately 70-90 cm, so that over a web width of 5 m approximately 5 to 7 Tube tubes 12 are placed side by side.
- FIG. 2 shows a relatively short protective tube mat 10, which is provided for covering a slope. Therefore, filling openings 13, which allow access to the tube tubes 12, introduced only in an upper end region.
- the protective tube mat 10 is closed at its respective ends with a transverse seam 14.
- Figure 3 shows a landfill 1, which has a bottom portion 2 and this embracing embankment 3.
- the embankment 3 rises to a slope crown 4 and then falls outwards again.
- the landfill 1 is already prepared by flattening the substrate and by applying a ground seal layer.
- FIG. 4 shows a possible laying plan for the landfill site 1.
- the dashed lines indicate the location of the embankment protection mats 10 to be erected later.
- the dotted lines indicate the location of the ground-protection tube mats 10 '.
- All protective tube mats 10, 10 ' can be prefabricated accurately to an allowance at the landfill corners 1, so that they fit accurately after laying and mutual bonding on the slope 3 and on the floor 2, even in curved areas of the slope.
- FIG. 5 shows the landfill site 1 with some protective hose mats 10, 10 'shown by way of example.
- a floor protection hose mat 10 ' is designed on the left edge, which extends over the entire length of the floor 2.
- the slope area 3 left next to a slope protection tube mat 10 is placed.
- the embankment mat 10 lies on top.
