Description

1 194243 • Reservoir

The invention relates to a reservoir provided with a base plate of in-situ poured concrete and an upright cylinder jacket of prefabricated bent jacket elements of reinforced concrete, the jacket elements having a vertical groove on both front sides, with opposite grooves of adjacent casing elements to form a space which is filled by a filling body, which serves as a sealing material, in the form of a sealing body, - in which tension elements such as cables are reciprocally spaced inside guides in the casing elements and by the filling bodies in the grooves movable to hold the cylinder jacket together in tensioned condition, - wherein the space of the guides surrounding the tensioning elements is partly filled with the filler body material, and - wherein the space of the guides surrounding the tensioning elements is partly filled with the filler material is filled, and 1 5 - the lower part of the cylinder jacket being pressed against the bottom plate by the pretensioning of the clamping elements.

A reservoir of this type is known from applicants DE 3,335,141 C2. In this reservoir, the jacket elements have a straight inner wall that extends to the bottom and the bottom plate connects to this inner wall. Complications can sometimes occur under special circumstances.

The object of the present invention is to provide a reservoir which can still be manufactured reliably while maintaining or reducing costs, and which, in particular with optimized short construction times, achieves excellent durability with solid connections.

This object is achieved according to the invention in that a niche is arranged in the bottom of each jacket element, which niche is open on the radial inner side of the element, and that the bottom plate extends into the niche and the bottom end of the grooves through the vertical grooves formed spaces.

Because the in-situ poured bottom plate extends into the niches, the jacket elements of the cylinder jacket are coupled in the radial and tangential direction, and if desired also in the axial direction, by the mold with the in-situ poured bottom plate, and the jacket elements are better held together.

The invention is elucidated in the following exemplary embodiment with reference to the schematic drawing, in which: figure 1 is a top view of a reservoir; Figure 2 is a section on line IMI in Figure 1; Figure 3 is an enlarged cross-sectional view of Figure 2 through a jacket element; Figure 4 is a top view, roughly to scale of figure 3, of a joint between two casing elements; Figure 5 is a view approximately on the scale of Figures 3 and 4 of the head end of a wall element in the region of the joint, with the recess formed at the bottom; and Figure 6 is a top view of the turnbuckle shown approximately on the scale of Figures 3,4 and 5.

The cylinder jacket 18,18 * of the reservoir 1 here consists, for example, of eight mantle elements 10,11. Cat can of course also be more or less elements.

In Figure 1, seven identical jacket elements 10 and one jacket element 11 with a liseen 4 are shown, all of which abut against each other at similar joints 12 (see also Figures 4 and 5).

The front side of each element 10 and 11 shown in Figure 5 is provided with a single groove 13 (compare also Figure 4), with rubber seals 14 being provided as pre-seals on the sides of the groove 13. The bottom of the groove 13 has a profile 15. Figure 5 also shows one of the tubes 16 and a clamping element 2 included therein.

50 Via the injection tube 17 shown in figures 3 and 4, which runs from the inside of the reservoir 1 above the bottom 5 into the grooves 13 of a joint 12, filler body material is injected into the grooves 13 from the bottom up. The filling body 3 is thereby formed.

Since in each joint 12 the grooves 13 are closed at their bottom ends by niches 51 protruding and engaging material of the bottom plate 5, no filler material material can be lost at the bottom 55.

The jacket element 11 has a liseen 4 (Figures 1 and 6), in which the end parts 20 of the clamping elements 2 intersect and, after clamping, are secured in storeys 22 by means of fastening devices 21.

In figure 3 it can be seen that in the lower part 18 of the cylinder jacket 18,18 'the tubes 16 and thus the clamping elements 2 incorporated therein are at a smaller distance from each other than in the upper part 18'. 5 The reinforcement 19 shown in figure 3 extends from the jacket elements 10 and 11 into the bottom plate 5. A foundation-like flat mounting ring 6, which is adapted to the substrate, is here both under the elements 10,11 and under the edge of the bottom plate 5 applied. A gravel bed 7 is arranged in a manner known per se between the base plate 5 and the ground 8. 10 The vertical reinforcement 9 serves as the main reinforcement, while a less heavy auxiliary reinforcement θ 'focuses more on the mounting condition. To manufacture the reservoir 1, the individual sheath elements 10 and 11 are first manufactured in a factory for precast concrete elements and brought to the construction site. A mounting ring 6 is built on the construction site, which is constructed depending on the construction site 8. A gravel bed 7 is fitted within the mounting ring 6. On the mounting ring 6 the cylinder jacket 18, 18 'is manufactured from seven jacket elements 10 and one jacket element 11 with a liseen 4. The tension parts 2 drawn in the tubes 16 are then lightly tensioned, so that the jacket elements 10 and 11 are held together. The bottom plate 5 is then poured into concrete on the mounting ring 6 and over the gravel bed 7, whereby bottom plate material is also introduced into the niches 51 formed at the bottom of the joints 12. Thereby a positive fit is obtained between the bottom plate 5 and the jacket elements 10, 11 and at the same time the lower ends of the grooves 13 are closed. Subsequently, the filling body material is injected into the grooves 13 from the bottom upwards through the injection tubes 17, which debouch above the bottom plate 5 in the reservoir 1. During this injection the hollow space is also filled, at least partly, which the clamping elements 2 leave in the tubes 16. The tensioning elements 2 remain free from the filling material; they can therefore slide freely into the tubes 16 and into the filler body 3. The assembly is given time to harden and the clamping elements 2 are then fully tensioned. The clamping elements 2 are fixed in the loops 4 and the plaster layer is applied. The rubber seals 14 have only a temporary sealing function, until the filling bodies 3 have hardened and the final tension of the clamping elements has been reached. 35 Reservoir, fitted with a base plate made of on-site poured concrete and an upright cylinder casing made of prefabricated bent shell elements of reinforced concrete, - in which the shell elements are provided on both ends with a vertical groove, whereby opposite grooves of adjacent shell elements form a space, which are filled by a filler body serving as a sealing filler material, 40. in which tensioning elements such as cables are spaced one above the other inside guides in the jacket elements and can be moved back and forth through the fillers in the grooves to be tensioned to hold the cylinder jacket together thereof, - wherein the space of the guides surrounding the clamping elements is partially filled with the filler body material, and 45. wherein the lower part of the cylinder jacket is pressed against the bottom plate by the pretensioning of the clamping elements, with the feature, that In every ma The counting element (10, 11) is provided with a niche (51) on the underside, which niche (51) is open on the radial inner side of the element, and that the bottom plate (5) extends into the niche (51) and the lower end of closes the spaces formed by the vertical grooves (13).
