Definitions
- the invention relates to a device for receiving, storing and dispensing flowable or pourable substances, in particular liquids, such as water or rainwater, for installation in the soil, which consists of at least two wall elements to form a cavity.
- tanks are used, which are introduced into the soil, i. are mounted underground.
- tanks are used, which are configured, for example, cylindrical, spherical, square or in a diamond-shaped base.
- These known in the art devices are often made of plastic, metal or a composite material.
- DE 19733589 A1 shows a generic device in the form of a cylindrical underground tank, which is formed from at least two elements and has stiffening ribs or beads on the circumference of the cylindrical surface.
- a second known, generic device is shown in DE 10052324 A1.
- This underground tank is also executed in a preferred embodiment, also in several parts, is characterized by an annular body and has to increase the load on stiffening ribs.
- the tank disclosed in DE 10052324 A1 has the advantage that no support devices arranged inside the tank are required by the stiffening ribs on the cylinder surface or hose surface.
- This object is achieved by a device having at least two wall elements to form a cavity in that the structural design of the wall surfaces takes place in such a way to increase or ensure the required mechanical strength of the tank that results in an increased structural strength.
- the teaching according to the invention recognizes that the mechanical design strength can be maximized by means of a tank wall formed in one piece and comprising a plurality of arched conversion elements, and at the same time the required use of material is minimized.
- the one-piece embodiment are prevented in sealing surface problems that inevitably occur by a multi-part structure.
- the advantage achieved by the invention is that the configuration of the tank wall as at least partially realized curved shape, the structural strength is increased such that additional stiffening elements in the form of ribs or beads are not required. Due to the one-piece embodiment, a construction without sealing surfaces or joining surfaces is supported. As a result of the realized reduced use of materials tanks can also with large tank volumes be carried out in one piece, since the achievable reduced material use contributes to the reduction of the total weight.
- the tank may be made of any known materials such as plastic, e.g. Polyethylene, glass fiber reinforced plastic, sheet metal or other known composite material.
- the tank can be realized in an annular, ideally oval-shaped, elliptical or any oval-shaped construction.
- the various structures have in common that they are at least partially formed by curved wall elements.
- the wall elements may be partially concave or completely concave or convex.
- the curvature can be formed in a circular arc with a constant or variable radius.
- the curvature of the respective conversion element can be configured elliptical.
- the bulges can continue to be formed by free-form surfaces.
- the surface pressure of the soil of the tank can be formed of different wall elements having an identical cross section at the respective transition points of wall element to wall element to support the one-piece design of the tank.
- the axial force component which occurs in each case on the surface element acts in the direction of the tank wall and generates a transverse force acting within the wall, which is also called a transverse force thrust.
- Essential for the dimensioning of the tank wall is the amount of the radial force component. Due to the concave or convex configuration of the respective wall elements and the angular relationships within the force parallelograms dependent thereon, the locally acting radial forces are reduced.
- the associated axial forces act in the longitudinal direction of the tank wall and can produce much higher tensile or compressive loads in terms of magnitude, which can be easily absorbed by the wall material.
- the tank is designed torus-shaped.
- the toroidal, ie annular design of the tank this is formed by a plurality of wall elements.
- the wall elements have a circular cross-section in the axial tank direction.
- the wall elements are formed by convex curvatures.
- the individual wall elements are designed in identical size and shape.
- Another embodiment of an annular tank can be formed by different wall elements. Both the use of concave and convex curvatures of the wall elements as well as their variation of the shape of the bulges may be present. It is also possible that different sized wall elements form a toroidal tank.
- the tank is designed quasi-oval.
- This quasi-oval tank shape is formed by differently configured wall elements.
- This embodiment may be constructed of wall elements with concave or convex or a combination of concave and convex wall elements.
- both the concave and the convex Wandungs comprise Schludge or completely concave or convex may be curved.
- the curvature can be configured in the form of a circular arc with a constant or variable radius, adjoining radii of different values or elliptically.
- wall elements are possible, which are constructed of free-form surfaces.
- the device according to the invention for receiving, storing and dispensing flowable or pourable substances has a ring shape deviating from the circular shape, for example an elliptical shape.
- a ring shape deviating from the circular shape for example an elliptical shape.
- attachments or elements such as eyebolts, pads, manholes, inspection openings or Ranbutzen etc. can be used.
- at least one separation point can be provided at least at one transition point from wall elements to wall elements. In this case, however, the advantage of lacking separating points achieved with the one-piece piece is abandoned.

- Fig. 1 shows a device for receiving, storing and dispensing substances for incorporation into the soil 1 in a first preferred embodiment.
- the tank 1 is designed torus-shaped, the bulges 5 of the wall elements 2 are different.
- the radii of curvature are indicated by RWx and RWx + n.
- the wall elements 2 Within the toroidal, ie annular configuration 10 of the tank 1, this is formed by a plurality of wall elements 2.
- the wall elements 2 have a circular cross-section 6 in the axial direction 10.
- the maximum wall diameter 6 lies with its radius Rz in the axial direction of a wall element 2.
- the wall elements 2 are each formed like a segment and similar to pie pieces joined together to form an annular structure of the tank 1.
- the use of the term "radius of curvature” does not mean that necessarily a circular geometry of the curvature must be present.
- the circular design corresponds to only one embodiment. In principle, any geometry of the curvature is suitable, which supports a branch of the applied compressive forces.
- the tank 1 may contain wall elements 2 that are different relative to each other, the individual wall elements 2 in particular having different curvature radii relative to each other.
- the radius Rz to be recognized in FIG. 1 corresponds to the radial diameter of a wall element 2. Again, the geometry of the wall element 2 does not have to be circular.
- the wall elements 2 have in the illustrated shape in the tank cross-section over a circle geometry and have a circular transition point 4 with a circular cross-section.
- the wall elements 2 can each be formed from a partial element of a spherical triangle.
- Fig. 1 shows the device 1 with evenly distributed over the circumference wall elements 2, characterized possesses each wall element 2 over the circumference of an equal circular arc. It is possible for the wall elements 2 to be of different sizes in the circumferential direction of the toroidal device. are guided, ie the wall elements 2 are at least partially asymmetric along the tank center line.
- the wall elements 2 are formed from complete spherical branches, so that there is a further connection point in the circle center of the device 1.
- the inner diameter Di of the tank 1 would be zero. It is possible to carry out this connection point in the center of the circle by means of a strut within the tank 1 and thereby increase the compressive strength again.
