Description

The invention relates to a storage facility for waste in the form of a with respect to a vertical axis of rotationally symmetrical large containers individual concrete segments, the wall surface of which is at least in one part is richly double-skinned and a space for inspection forms purposes.

The permanent storage of waste, especially those that more or Containing less dangerous substances creates increasing difficulties. In conventional landfills, it has been shown in many cases that Hazardous substances can enter the groundwater and flow on from there be sported. It has therefore become common to landfill areas through foils cover and thus seal liquid-tight. Slides can each but are destroyed, and in particular there is a construction hardly any possibility of early detection of leaks.

It is therefore also known to mul the site intended for a landfill to be dug out and to be versed with a double-shell concrete tub hen, which contains a walk-in space for inspection purposes. However, here is a relatively high effort in relation to the capacity required to the landfill.

Cylindrical large containers with a better capacity Diameter from about 50 to 100 m and corresponding height, which from individual concrete segments from top to bottom while excavating the Bottom can be made inside the container. With these containers is it is also known to inspect passages below the floor hen. Here, too, the cost is considerable.

The invention is therefore based on the object of a bearing device in the Form to create a large container that is relatively small Material costs can be produced.

This object is achieved in that the large container is essentially spherical and made of precast reinforced concrete consists of an inner plate, an outer plate and a support device  device that connect the plates to form a gap det.

The biaxial curvature of the spherical shape leads to particularly favorable statics conditions that enable a corresponding material saving. Due to the composition of the large container made of precast concrete the construction of the large container is simplified.

The large container is at least partially, i.e. up to the equator line, embedded in the floor. The excavation can be used as a fill for the upper one Part are used so that the impression of a Hü gels that can be planted.

The individual precast reinforced concrete elements can have a triangular, pentagonal, have hexagonal or other polygonal outline. There are a number system for dividing a spherical surface into a limited number of approximating polygonal partial areas, such as in footballs or is the case with golf balls.

The support device that connects the inner and outer surface and at the same time at a distance, can consist of one or more columns, struts or the like Chen exist.

Further refinements of the invention result from the subclaims chen.

Fig. 12 is a partial cross section through a wall region of the large container.

Fig. 1 shows a spherical large container 10 , which is built into an approximately hemispherical trough 12 buried in the ground, so that the large container is embedded approximately up to the equator line in the original bottom surface 14 . The resulting excavation and possibly further Bo forms a fill 16 on the protruding part of the spherical bulk container from the bottom surface, which also forms a ramp 18 that allows the approach of garbage trucks. In the area of the ramp 18 there is a throw-in opening (not shown) for waste. From this throw-in opening, a distribution system, not shown, starts in the interior of the large container, which enables a uniform filling of the large container and includes, for example, an overhead crane.

The wall of the large container consists of individual elements in the form of prefabricated reinforced concrete, which form a double-shell wall construction with a hollow space, as will be explained in more detail later. Between the inner and the outer plate of the individual finished parts are the supporting devices that keep them at a distance. In Fig. 1, a first type is a finished part 20 with inclined struts as a support means and to the right of another type (22) with support columns shown on the left side.

Fig. 2 shows an example of a composition of the surface of a sphere of hexagonal elements and a few pentagonal elements. One of these pentagonal elements is located, for example, in the center of the circle shown in FIG. 2.

Fig. 3 shows a spherical surface, which is composed of triangles. Here, too, the triangles form a pentagon in some points of the surface, but otherwise a hexagon.

FIG. 4 is a section of the spherical surface according to FIG. 2.

Fig. 5 shows a first embodiment of a finished part 24 as a wall element for the inventive spherical surface. The prefabricated part shown has an inner plate 26 and an outer plate 28 made of concrete, which are parallel to one another and connected by a support or column 30 in the center and at the same time kept apart.

Fig. 6 in turn shows a triangular inner plate 26 and a triangular outer plate 28 which are connected by a support 32 lying in a corner of the triangles.

Referring to FIG. 7, the triangular inner and outer panels 26, 28 interconnected by three located in the corners of columns 34, 36, 38.

Fig. 8 shows a finished part with a triangular inner panel 26 and outer panel 28, the oblique by three struts 40, 42, 44 are connected, which run from the corners of the inner plate 26 to the center of the outer plate 28.

Fig. 9 shows a finished part with a hexagonal inner plate 46 and outer plate 48 of hexagonal. These plates 46 , 48 are connected to one another via a support or column 50 arranged in the middle.

Fig. 10 shows the two hexagonal plates 46 , 48 , which are connected by three supports 52 , 54 , 56, which are located at three corners of the hexagonal plates.

Referring to FIG. 11 are inner plate 46 and outer plate 48 by three oblique struts 58, 60, 62, the plate from the center of the outer run 48 to three corners of the inner plate 46.

Fig. 12 shows a wall section from the spherical container from the substantially perpendicular part of the wall. It can be seen that the individual finished parts with their inner and outer plates together form an inner shell 64 and an outer shell 66 , which are connected to one another by supports or columns 68 and are supported against one another to form a cavity. In this space, a mobile Ge advises 70 is indicated, in which a pendulum-suspended passenger compartment 72 is arranged, the surface always adjusts vertically in view of the constantly changing inclination of the ball. This passenger compartment 72 serves to accommodate the control personnel.

Channels are provided in the panels of the elements, through which in the Monta the tensioning strands with which the elements are connected and can be tensioned.

To seal the container, the surfaces can be sealed with a suitable seal be coated with medium, for example with sealing slurries, paints Latex or the like. Films or bitumen sheets or the like can be glued on. Sheets made of stainless steel, copper, Lead or other metals of the appropriate size are placed in the formwork and in egg can be concreted in one operation.

Seals are placed in the joints between the finished parts Clamping the finished parts are pressed together and so contribute to the sealing of the joints.

Precast concrete parts are considered to be particularly advantageous which have only one support or column for connecting two plates, which is supported in the center of the two plates, as shown in FIGS. 5 and 9. With precast concrete parts of this type, high, essentially punctiform loads at the corners of one or both slabs are avoided, as can possibly occur in the other embodiments. Furthermore, a simpler mold with only two parts can be used, while four-part molds are necessary for finished parts according to FIG. 7, 8, 10 or 11.

For prefabricated parts with a support or column, the plates can be three, four, be pentagonal or hexagonal or polygonal in some other way.  

As shown in FIGS. 5 and 9, the supports or pillars can merge into the two plates in a bow or cone shape at both ends. This enables the reinforcements to be placed in a structurally advantageous manner.

The supports or columns can be polygonal, round or angled in cross-section broadly shaped.
