Abstract: The invention relates to an arrangement for closing building openings in a watertight manner, wherein a frame is arranged at right angles on a watertight, stable covering panel, all the way round the latter and at a constant spacing from a wall of the building opening, and at least one pressure hose with an openable and closable pressure-hose connection is arranged all the way round the frame, and a periphery of the covering panel that projects beyond the building opening has, on the building side, an all-round sealing element and at least one swing-away handle is arranged on the outside of the covering panel, and projecting parts of the building opening are surrounded by the periphery of the covering panel such that the periphery of the covering panel, with the all-round sealing element, encloses the building opening in a watertight manner.

Abstract: System for protection against high waters is constructed from assembled protective walls, fixed on the ground/dam and interconnected between them selves, each to another. Each protective wall 1 contains, in its body, a first edge 1.1 and second edge 1.2, that are positioned under right angles, lying from the both sides of the guiding plates 2. The guiding plates 2 stands forward, over the body, with the edge 1.1, whereby it forms first gap S1 in the U-shape in the form of slot, and two other guiding plates 2, formed the second edge 1.2 that creates second gap S2 in the form of slot. The third edge 1.3 is extended from the upper side, while the fourth edge 1.4 is parallel with the second edge 1.2 while in the gap S2, between guiding plates 2, the protective wall is attached as a slider. The guiding plates 2 are arranged on the first edge 1.1, appropriately distanced from the fourth edge 1.

Abstract: The mobile protection against high waters that is contained from transportable structural elements that are water proof and that can be filled or emptied with water where the structural elements can be placed aside each to other and each over other, taking the shape of rectangular vessels (1) in case of linear flow of the protective wall against high waters and the shape of key segments (2) when the flow is curved. The hook hanger (9) represents easy up cap with opposite hooks (20) to the structural elements that lay across it. The easy up caps at the segments (2) have additional prolongation of the basic plate (19) because of the assurance of the segments (2) with the vessels (1) throughout the opposite hooks (20). The vertical jacket element (8) is in shape of half-profile, and it is unsolvable adhered over the layer of caouchouc. The jacket element (10) from the segment (2) has a profile in shape of mushroom. The jaws (17) are made of PE-HD-plate with inserted steel tops.
