Abstract

The longitudinal sides of the U-shaped, bent, steel profiles (1), with length dependent on the expected water level, from an arcuated structure, oriented w.r.t. the ground and are bolted together. Thus the wall forms a ventilated structure diverging the water pressure to the vault stringers. Pref. the thrust forces, diverged to the stringers are taken up by an underground construction, if required, or by the existing building structure.

Description

a) The steel profiles 1 have a bevel of about 10 cm width on both sides. This bend is not at right angles, but is bent at an angle that deviates slightly from 90 degrees and is derived from the radius of the arc. The bends are drilled at a distance of approx. 0.50 m for screwing the steel profiles together. The screws are screwed together using a quick screw system similar to that used in scaffolding. The tightness between the longitudinal sides of the steel profile takes place in that the arching action presses the longitudinal sides against one another. It is the same process that occurs in every vaulted structure in the building. If necessary, sealing strips made of elastic rubber-like material can be inserted between the folds.
b) A rib-like steel profile 4 is provided on the inside of the vault to stabilize the vault and to ensure that the vault thrust is properly derived from the fighter points, which has the same effect as the ribs in church vaulting.
c) The triangular interception structure 3 to be erected at the so-called fighter points consists of steel profiles which are also screwed together by means of the aforementioned quick screw system. The distance of these fighter points is the span of the (horizontal) vault. It can be set up to approx. 8.00 m without excessive forces.
d) All steel profiles are so light in weight that they are of one Person can be worn.
e) The places and the floor in the arch area where the protective wall is provided must meet certain requirements for this purpose, namely

1) Be flat and free from obstacles

2) For the triangular construction described under c, an abutment must be provided in the earth area according to the horizontal thrust that occurs. If the protective wall is at a short distance from the building, the pushing forces can be directed into the building in question using simple supports lying on the floor.
These measures are relatively easy to carry out, but must be done for the First planned and prepared, but are then for everyone further re-establishment reusable.

Achieved advantages

Einfache Methode mit der ohne Hilfsgeräte in kürzester Zeit eine Hochwasserschutzwand bei Bedarf errichtet werden kann. Das Aufstellen ist nicht schwieriger und zeitraubender als der Aufbau einer Zuschauertribühne und brauch daher erst dann zu erfolgen, wenn die Hochwasserprognosen dies erfordern.Simple method with one without auxiliary devices in the shortest possible time Flood protection wall can be erected if necessary. The putting up is no more difficult and time consuming than building an auditorium and therefore only need to take place when the flood forecasts require this.

Es wird nur für die Zeit der Hochwassergefahr der betreffende Bereich sei es nun eine relativ schmale Straßenzufahrt oder eine größere Gebäudefront, abgeriegelt und auch nur während dieser Zeit ist die Sicht versperrt. Z. B. die anläßlich des Hochwassers diskutierte Erhöhung der Kölner Uferschutzmauer und die damit verbundene, auch städtebaulich unmögliche, bleibende Sichtversperrung auf den Rhein wäre vom Tisch.It will only affect the area in question during the period of flooding be it a relatively narrow street entrance or a larger building front, the view is blocked off and only during this time blocked. For example, the increase in. Discussed during the flood Cologne bank protection wall and the associated, also urban planning impossible, permanent obstructions to the Rhine would be off the table.

Die Stahlprofile lassen sich als einfache lehnenlose Parkbänke in unmittelbarer Nähe der für das Hochwasser zu errichtende Schutzwand aufstellen. Es werden dadurch Lager- und Transportkosten gespart. Die Stahlprofile lassen sich durch einfach ab- und anzumontierende Lehnen und Sitzauflagen in komfortablere Sitzbänke verwandeln. Sie sind gegenüber Holzkonstruktionen darüber hinaus fast unbegrenzt haltbar. Die Investitionskosten der Hochwasserschutzwand dienen somit einer weiteren nützlichen Maßnahme der öffentlichen Hand, wie z. B. der Freiraumgestaltung im Uferparkgelände.The steel profiles can be used as simple backless park benches the immediate vicinity of the protective wall to be erected for the flood put up. This saves storage and transport costs. The Steel profiles can be easily removed and attached to the backrests and Convert seat cushions into more comfortable benches. You are opposite Furthermore, wooden constructions have an almost unlimited shelf life. The investment costs the flood protection wall thus serve another useful public measure, such as B. the Open space design in the riverside park area.

Claims

1. Mobile flood protection wall, characterized in that on the long sides U-shaped steel profiles, the length of which depends on the height of the flood to be prevented, in a vertical position, based on the plan, arched, set up, screwed together and thus by the arched Set up a vault that derives the water pressure on the fighters of this vault.

2. Mobile flood protection wall according to claim 1, characterized in that the thrust forces derived from the fighters are derived from a structure designed as required in the subsurface or to existing structures. TECHNICAL FIELD OF THE INVENTION The invention relates to a system for erecting a protective wall against flooding, namely:

a) against high water levels.
b) which can be erected quickly if necessary.
c) that not only narrow passages such. B. can block dyke openings.

No such systems are known. The object of the invention was to develop a system which made it possible to erect a protective wall in the simplest possible way, if possible without any large technical auxiliary device, with the least effort and in a short time . 50 cm wide steel profiles ( 1 ), which are bent in a U-shape, with a length that is required depending on the requirements (equal to the required height of the flood to be prevented) are screwed together vertically on their long sides. The arrangement of the steel profiles is arched based on the floor plan. The steel profiles arranged in this way thus form a horizontal vault and divert the horizontal water pressure to the respective so-called fighter points ( 2 ), as these points are called in vault construction. A steel structure ( 3 ) is installed to divert the thrust forces that occur at the fighter points, and divert the shear forces into the ground. The execution of this steel structure can be done in different ways and will depend among other things on the size of the forces occurring. A truss-like triangular construction is the simplest solution.
