DESCRIPTION:
BRIEF SUMMARY
The invention relates to a large container for accommodating pourable,
pasty and sludge-like materials which essentially has the shape of an upright cylinder, and also to a method in which these containers can be used.
Large containers for the above-mentioned materials primarily have concrete walls or steel walls; other materials are also conceivable here, for example plastic walls. However, the disadvantage of all these containers is that the costs are relatively high. This may not be troublesome if the material is high-grade or, for example, inflammable. The application possibilities of such previously known containers is therefore limited.
Another disadvantage is that no liquid can escape through the walls. Therefore no sludge or mud for draining the same can be stored in such containers. On the contrary, the procedure is adopted of first depositing the mud behind sand dams and the like where it can drain. This normally takes a very long time, because in humid regions more water always comes from above in the form of rain. After sufficient draining, the mud can then be taken to another place for the final dumping, which requires a considerable amount of work.
In a large container of the type mentioned at the outset (East German Patent Specification No. 93,511), textile material is provided as a component of the wall material. However, this container is still very expensive, because it requires special stabilizing rings for absorbing the high circumferential tensile forces of the filled container and also permanent supporting structures. These stabilising rings and supporting structures cannot be removed after the container is filled, because otherwise the container would no longer be stable. Since it conflicts with the recognized rules of architecture to install additional bulky objects which cannot decay such as masts, steel ropes, etc., in dump sites and since these parts are in addition very expensive, the container can only be used in special cases.
A further previously known container (East German Patent Specification No. 84,588) likewise requires permanent supporting structures and in addition a special woven fabric. Finally, in the case of this container, as can be seen from the figures, it is obvious that only a relatively small container is intended and not a large container.
The object of the invention is to create a simply constructed large container which is inexpensive and can be used for purposes for which large containers could not be used previously, and which is suitable in particular for the inexpensive and space-saving processing of sludge and mud into dumps or for using in the casting of concrete.
The solution according to the invention is that the side wall is made of a textile material which is strengthened with woven fabric reinforcements which are arranged diagonally to the directions of the weft and warp.
The side wall of the container according to the invention is therefore made exclusively of textile material. Any stabilizing rings or the like are not necessary. Also not necessary are permanent supporting structures which at most have to be used just partly during the filling of the container, but can be dismantled when the container is completely filled.
As a result of the invention, a large container is created for the first time, the walls of which are made exclusively of textile material. The prejudice is thereby overcome that walls made exclusively of textile material cannot resist the forces occurring in a large container. That this is possible is because it is achieved quite substantially by the woven fabric reinforcements arranged diagonally to the directions of the weft and warp, as a result of which woven fabric reinforcements the container can no longer distort unsymmetrically. Previously, expensive permanent supporting structures had to be provided in order to avoid these possibilities and problems.
Stable textile materials suitable for the container according to the invention are, for example, the geotextiles which are used for stabilizing ground structures. At t
