Definitions

• the invention relates to a device for temporarily establishing a flood protection line.
• sandbags As a mobile flood protection device, sandbags are known which are stacked along a flood protection line in order to build a dam.
• the major disadvantage is that both the erection and the subsequent dismantling of such a dam are associated with a very high expenditure of time and work.
• Another disadvantage is inefficiency, since the sandbags cannot be recycled.
• the object of the invention is therefore to create a device for temporarily erecting a flood protection line which avoids the aforementioned disadvantages, but nevertheless reliably and reliably protects against floods.

• the single angle element has a triangular cross section. Since the individual angle element stands with its underside on the base, its front, which forms the dam for the flood, is inclined relative to the base. Thus, the water pressure for the individual angular element creates a force component that acts vertically in the direction of the base. Likewise, the back of the individual angle element, which forms the support wall for deriving the water pressure acting on the dam wall, is inclined with respect to the base area. Viewed overall, this results in a very high level of stability for the device according to the invention.
• the individual angle element can be open on its transverse sides, since no forces have to be dissipated here, i.e. the individual angle element can be designed as a simple angle profile.
• the underside of the individual angle element is open.
• the individual angle element with the lower edges of its front and back stands on the base. Because this significantly reduces the effective contact area of the individual protruding element, the force component acting vertically from the water pressure in the direction of the base area also increases, which further increases the stability of the device according to the invention.
• the individual angle elements can be stacked on top of one another or in one another in a particularly space-saving manner, so that the device according to the invention requires only a small storage space in flood-free times when it is not required.

• Angle elements can be covered by means of a tarpaulin or film in order to achieve tightness.
• the tightness is achieved in that the at least the front sides serving as a baffle wall form angled angular elements which form a substantially flat or smooth contact surface for the tarpaulin. Because due to the flat or smooth contact surface, the tarpaulin is subjected to an even contact pressure under the effective water pressure. Because the tarpaulin lies evenly, the risk is minimized that the tarpaulin will be torn by flotsam impacting under the flow of the flooding and thus lose its tightness.
• Holding elements such as weights or the like, must be fixed to their To prevent abortion under the influence of the flood. Since such holding elements result in a tension of the tarpaulin under the action of the flood, it is provided that the outer longitudinal edge of an angle element has a radius of preferably about 30 millimeters. As a result, there is no, so to speak, a sharp edge at which the tarpaulin could enter.
