Definitions

  • the invention relates to a walk-through sole construction for a landfill with which the load of the landfill body is released on supports and further on foundations and the subsurface and on which layers of sealing material, drainage material or protective material lie, which are connected to a drainage system for the leachate.
  • the aim is to reliably collect and collect all sikker water, to be able to easily check the reliability of the sealing system at any time and to quickly identify and remedy damaged areas.
  • Another aim is to be able to collect leakage water or leachate in the event of damage using a second system.
  • Sealing with a cellar-like cavity is many times more expensive and complex than previously used seals, but it has the advantage of being able to visually check and secure the seals at any time in a simple manner.
  • the landfill body rests on a concrete slab that has a basement.
  • the basement is accessible.
  • the concrete construction can be done in in-situ concrete or precast construction.
  • the main sealing function is performed by a suspended plastic seal (similar to a suspended ceiling) that clings as closely as possible to the basement ceiling and has elastic properties.
  • the platform top is divided into individual fields by raised field boundaries.
  • the leachate is recorded field by field and analyzed for its nature.
  • the present invention is based on the object to improve a walkable, controllable and repairable sole construction under a landfill so that it for a long time rooms is highly resilient and tight in the long term and can also adapt to the deformations of the surface without damage.
  • the object is achieved in that the sole construction consists of individual support elements separated by joints with an upwardly convex or concave shape, the surface of which is inclined towards the supports which rest on supports arranged in a grid and which at the same time collect zones for the leachate form, which are connected to the cleaning system via the drainage system.
  • the individual support elements transfer their loads to the supports arranged in a grid, which are based on the existing floor conditions, for example on simple block foundations.
  • the shape of the support elements ensures that the leachate flows, without crossing a joint, over a short distance to the associated collecting zone, from where it is drained into corresponding drain lines to the cleaning system.
  • the drainage system can be present several times in order to separate the seepage water from different zones according to its pollutant content and treat it separately.
  • the leachate flowing out of the collecting zones can first run through a sight glass for visual control, which is equipped with a device for measuring the amount of leachate and a drain tap for taking samples. The leachate then flows through a flexible, reversible hose into a drain line of the corresponding leachate category.
  • the support elements can be designed in detail according to claims 2 to 5.
  • Cross vaults or folding structures are equivalent components.
  • the upwardly convex supporting elements are designed as three-axis cross vaults or arch-like folding structures which are statically fixed on three supports, so that they can follow an uneven setting of their supports without constraint stresses.
  • support elements that are concave upward are preferably given only one central support.
  • Each support has two tasks to fulfill, according to claim 6, namely that it must on the one hand pass the bearing forces of the support elements onto the foundations and on the other hand it forms the collecting zone for the seepage water flowing off on the back of the support elements.
  • the cavity in the hollow supports and immediately above the supporting elements is filled with a well-permeable material (sand, gravel, etc.) and well compressed.
  • the shape of the vaults or the folding structures is designed in accordance with the support line, so that they are essentially only subjected to pressure and any bending stresses that may occur remain small.
  • the support line is a standing half-ellipse.
  • the support elements have closable openings through which lances which can be pushed up into the landfill body can be inserted. With the aid of these lances, measurements of parameters of the chemical, physical or biological processes taking place there can be carried out and substances can be added or extracted in the landfill body.
  • the joints between the individual supporting elements according to claims 4 to 12 remain movable for the entire life of the sole structure or are closed or they decay as the movements subside can be designed to be closed from the start if the shape-changing capacity of the construction allows for this with regard to the expected shape changes of the subsurface and the load-bearing capacity and tightness of the construction remain guaranteed.
  • Movable joints are only guided along a fall line so that no seepage water flows towards them, but only runs parallel to the joint.
  • the capstone lying over the joint has the task of bridging the open joint and the loads in this area on the two neighboring supports transfer elements.
  • This space can also be squeezed out watertight with a suitable mass, this mass being such that it can be removed from the inside and can be replaced with a new one at any time and as often as required.
  • a further sealing layer inclined above the collecting zones for the leachate with an overlying drainage layer is arranged above the supporting elements and the layer of protective material as well as the layer of drainage material above it, which has downpipes with the collecting zones and the drainage system for the leachate are connected.
  • FIG. 1 and 2 show a sole construction 1 with triangular cross vaults 18 via supports 20 or hollow supports 45 arranged in a triangular grid.
  • FIG. 3 shows a triangular cross vault in a single axionometric view
  • FIG. 4 shows an axionometric view of a section through the sole construction 1 with three-axis cross vaults 18 and a landfill body 2 arranged above it.
  • FIGS. 1 to 4 show a triangular cross vault in a single axionometric view
  • FIG. 4 shows an axionometric view of a section through the sole construction 1 with three-axis cross vaults 18 and a landfill body 2 arranged above it.
  • the triangular cross vault 18 according to FIG. 3 is only one possible embodiment in embodiment 1 of the invention.
  • a three-sided folding mechanism can also be used. Any person skilled in the art is able to replace cross vaults with appropriate folding mechanisms within the scope of the present invention.
  • a walk-in basement 3 from which the joints, which will be explained in detail below, and the components of the drainage system can be checked and repaired.
  • a three-axis cross vault 18 consists of three firmly connected vault parts with an outwardly facing surface 43.
  • the upper Surface 43 of the three-axis cross vault 18 is designed in such a way that the leachate runs along water flow arrows 42.
  • the individual supporting elements or three-axis cross vaults 18 are separated from one another by joints 51, 52 and 53, which are explained in more detail below.
  • Each three-axis cross vault 18 rests on three supports 19.
  • the supports 19 rest on supports 20 and 45, respectively.
  • the supports 19 rest on the corresponding edge regions of supports 20 or hollow supports 45, as shown in FIGS. 1 and 4.
  • the supports 20 and 45 as can be seen above all from FIG. 4, have hexagonal edge regions 21 for the supports 19. 1, 2, 3 and 4 it can be seen that the entire sole construction 1 of the waste landfill is made up of individual support elements 18 which are separated by joints and which are convex at the top. This results in collecting zones 44 for the leachate which are distributed over the sole construction and which, as can be seen in FIG.
  • a lockable drain pipe 10 is connected directly to a lockable drain pipe 10 via a cavity 46 of the hollow support 45 or, in the case of solid supports 20.
  • An opening for taking leachate water samples can also be connected to the sight glass 11.
  • the changeable hose 12 is connected on the basis of the sample taken to the drain line 13 which is intended for the respective leachate.
  • a sealing layer 63 with an overlying drainage layer 64 can be arranged above the layer 8 of drainage material.
  • the landfill body 2 lies on the drainage layer 64.
  • the sealing layer 63 and the drainage layer 64 are inclined. Downpipes 65 are arranged at the lowest point and lead to the lowest point of the collecting zone 44 or the hollow supports 45.
  • the leachate is thus drained off in two ways: firstly via the downpipes 65 and secondly along the water flow arrows 42 over the surfaces 43 of the three-axis cross vault 18. It is essential that the majority of the leachate occurring is already on the surface of the sealing layer 63 via the Downpipes 65 is derived and thereby the aggressive leachate from the surfaces 43 of the three-axis cross vault 18 as far as possible. It can be seen from the figures that the water flow arrows 42 never cross one of the joints 51, 60, 61. This special feature of the sole construction 1 contributes significantly to its tightness.
  • the load from the landfill body 2 is transferred via the three-axis cross vaults 18 and the supports 20 and 45 into foundations, in the exemplary embodiment shown block foundations 4, which derive the load into the subsurface 5.
  • Fills of non-cohesive material 6 are provided between the block foundations 4. It is hereby achieved that although the weight of the landfill body 2 can cause strains due to the settlement depression, these stretches cannot then be reversed.
  • lances 49 also show closable openings 48 through which lances 49 can be pushed up into the landfill body 2 from below.
  • the lances 49 are connected to gas lines 50.
  • Part of the lances 49 can also be used to measure 2 state variables in the landfill body, e.g. To carry out temperature, oxygen content etc. or to supply these substances and to control the physical, chemical or biological decomposition processes taking place in the landfill body 2 or to control them in a desired direction.
  • the sealing layer 63 can be made of material that is inexpensive compared to the layer of protective material 9. This layer intercepts most of the leachate and the downpipes 65 fed. As a result, the expensive layer 9 of protective material can be protected and its service life can be increased.
  • the supporting elements in general can be made from different building materials and according to different building methods.
  • building materials come into consideration reinforced concrete, steel fiber concrete, cast steel, steel GVK "glass fiber reinforced plastic o and similar pressure-resistant and as resistant as possible to the polluted seepage waters.
  • steel fiber concrete, cast steel, steel GVK glass fiber reinforced plastic o and similar pressure-resistant and as resistant as possible to the polluted seepage waters.
  • Fig. 4 reveals capstones 62 over the joints explained in detail below, which in preferred exemplary embodiments are arranged over the joint area to be protected.
  • FIG. 5 shows a top view of a sole construction 1 with four-axis cross vaults 23. These have supports 24 which rest on square edge regions 26 of supports 25. If the collecting zones for the leachate are connected directly to the drainage system 10, 11, 12, 13, the supports 25 can be designed as full supports. But they can also be designed as hollow supports.
  • FIG. 6 shows the schematic plan view of six-axis cross vaults from which a sole construction 1 can be constructed with the interposition of joints 51, 60, 61.
  • the six-axis cross vaults 28 have supports 29 which can rest on hexagonal edge regions 31 of supports 30.
  • FIG. 9 schematically shows a top view of a sole construction 1 made of four-sided funnel-like support elements 33. They have supports 34 which rest on square edge regions 36 of central supports 35.
  • the supports 35 can be designed as hollow supports or as solid supports if the collecting zones 44 are connected directly to the drainage system.
  • FIG. 7 shows the schematic plan view of a sole construction 1 with hexagonal funnel-like support elements 38.
  • the supports 39 rest on hexagonal edge areas of supports 40, which can be designed either as hollow supports or as solid supports.
  • FIG. 8 shows an embodiment of a sole construction 1 consisting of individual four-sided funnel-like support elements 33 placed next to one another, which are supported by a single, centrally arranged support 35.
  • the supports 34 of the four-sided funnel-like support elements 33 rest on square edge regions 36 of the supports 35.
  • the upper sides of the support elements 33 are concave at the top, so that the leachate initially flows into the collecting zone 44 for the leachate within the funnel-like support element 33 and from there through the hollow support 45 Get support 35. They then flow into the cleaning system as already described with reference to FIGS. 1 and 4 .
  • a support group of several supports can be designed and the collecting zone 44 can be connected directly to the drainage system.
  • Movable joints between the individual support elements 18, 23, 28, 33 and 38 essentially prevent the formation of cracks in the sole structure 1 due to settlement differences of the individual supports 20, 45 in the case of an unfavorable subsurface 5. In such cases, the movable joints 51 remain permanent or until movable for subsidence subsidence.
  • the originally movable joints can then be closed.
  • Persistent i.e. Joints 61 which have already been closed from the start can be implemented if the changes in shape of the sole construction 1 are only very small as a result of the settlement and can therefore be absorbed by the material of the supporting elements without the risk of cracking.
  • the cover block 62 which is U-shaped in cross section, covers the region of the joint 51 and lies with its two support surfaces on the mutually facing edges of the support elements 18, 23, 28, 33 and 38 .
  • the resulting joint 47 simultaneously forms the outer sealing system 51.
  • the inner sealing system 53 consists essentially of an elastically deformable seal 55 which is stretched between opposing wedge-shaped grooves 57 in the edges of the support elements 18, 23, 28, 33, 38.
  • a clamping plate 56 is provided, which is fastened by means of screws in the manner shown in FIG. 10 between the opposite edges of the support elements.
  • a freely drainable space 54 which can also be filled with a waterproof mass 48.
  • a drain hose 59 is used to drain the leachate from this area of the outer seal.
  • the waterproof material 48 can be made of PUR foam, for example, and if necessary removed or replaced at any later time and as often as desired with a new filling. If seepage water penetrates through the joints 4 r between the cover brick 62 and the edge areas of the supporting elements, this seepage water that has penetrated is discharged in a controlled manner through the drain hose 29 and fed to the drainage system 10, 11, 12, 13.
  • FIG. 11 shows a further two-part sealing system for a permanently movable joint 51.
  • the cover stone 62 lies on an outer sealing system 52, which consists of drain mats 66 resting on the supporting elements 18, 23, 28, 33, 38 and neoprene extending along the joint 51 -Profiles 67 exists.
  • the freely drainable space 54 is closed off by an inner sealing system 53 with an elastically deformable seal 54 towards the walkable sole construction 1.
  • the inner seal system 53 can be easily removed for inspection and repair of the outer seal system 52.
