Abstract

Flood protection system comprises a base plate (30) having a device connected to the base plate consisting of a recess on the edge of the base plate and reinforcing elements protruding into the recess. The recess is dimensioned so that two opposite-lying base plates can be joined using cast concrete. An independent claim is also included for displacing protective elements of a flood protection system. Preferred Features: The reinforcing elements are formed as a connecting reinforcing loop. The base plates are joined using cast concrete so that the reinforcing loop and the recesses are cast.

Description

Die Erfindung betrifft ein Hochwasserschutzsystem typischerweise mit einer Vielzahl von Schutzelementen, bei dem durch hochklappbare Schutzelemente ein Hochwasserschutz errichtet wird.The invention relates to a flood protection system typically with a plurality of protective elements, in which flood protection is erected by folding protective elements.

Hochwasserschutz ist insbesondere in dichtbesiedelten Gebieten, die durch Flüsse, Seen oder auch durch ihre Meeresnähe hochwassergefährdet sind, ein bekanntes Problem. Aber auch zum Schutz wichtiger ziviler oder sogar militärischer Anlagen und Einrichtungen ist ein funktionierender Hochwasserschutz eine immer wichtiger werdende Aufgabe. Während in Gebieten mit häufigem oder ständigem Gefährdungspotential, insbesondere in Küstengebieten mit Sturmflutgefahr, üblicherweise Deiche mit einer dem maximalen Gefährdungspotential entsprechenden Schutzhöhe zum Einsatz kommen, wurde lange Zeit in Gebieten mit nur gelegentlichem Hochwassergefährdungspotential auf Notmassnahmen, z.B. mit dem Schutz von Gebieten mit Sandsäcken oder ausnahmsweise mit Dammbalken, bei akuter Gefahr zurückgegriffen.Flood protection is a well-known problem especially in densely populated areas, which are threatened by rivers, lakes or also by their proximity to the sea. But also for the protection of important civilian or even military installations and facilities a functioning flood protection is an increasingly important task. While in areas with frequent or permanent hazard potential, especially in coastal areas with storm surge danger, usually dikes with a maximum hazard potential corresponding protection height are used, was long time in areas with only occasional flood hazard potential on emergency measures, e.g. with the protection of areas with sandbags or exceptionally with dam beams, resorted to in acute danger.

Insbesondere an Flüssen und anderen Gewässern mit ähnlichem Gefährdungspotential war aber seit langem auch ein anderer Hochwasserschutz bekannt und üblich, nämlich die Flutung von speziellen Überflutungsgebieten, bei denen, z.B. als Wiesen, kein nennenswerter Schaden zu befürchten war. Durch dieses gesteuerte Fluten wurde der Hochwasserpegel an den gefährdeten Stellen massiv gesenkt und damit das akute Gefährdungspotential vermindert.In particular, on rivers and other waters with similar potential danger but also another flood protection has long been known and common, namely the flooding of special flood areas where, for example as Meadows, no significant damage was to be feared. Through this controlled flooding, the flood level was massively reduced at the vulnerable places and thus reduced the acute hazard potential.

Durch gestiegenen Zivilisationsdruck aber wurde die Ausweisung von entsprechenden Überflutungsgebieten immer schwieriger, so dass in den letzten Jahren an vielen Stellen der Welt Überschwemmungen auch von besiedeltem Gebiet mit untragbar grossen Schäden auftraten. Zudem ist auch das von den Gewässern ausgehende Gefährdungspotential dadurch angestiegen, dass insbesondere Flüsse mehr und mehr begradigt, kanalisiert oder auf andere Art eingeengt wurden, so dass ihnen ihre natürlichen Ausweichmöglichkeiten im Hochwasserfall genommen wurden.However, increased civilization pressure has made the designation of floodplain areas increasingly difficult, with the result that in many parts of the world in recent years floods have also occurred in populated areas with unacceptably high levels of damage. In addition, the risk posed by the waters has also risen as a result of the fact that rivers in particular have been straightened, channeled or otherwise narrowed, so that their natural alternatives have been taken in the event of floods.

Grundsätzlich ist es möglich, mit Dämmen und Deichen entsprechender Bauhöhe die Gefährdung von besiedeltem Gebiet zu mindern oder ganz auszuschalten. Allerdings verlaufen die Grenzen zwischen dem Gewässer, von dem die Gefährdung ausgeht und den gefährdeten Zonen in vielen Fällen gerade in besiedeltem Gebiet, so dass eine Verbauung mit solchen Dämmen und Deichen nicht auf die zur Sicherung notwendige Akzeptanz stösst. Zumeist wird zudem gewünscht oder verlangt, dass die baulichen Massnahmen nicht oder nur wenig störend wirken, wenn die Gefährdung nicht akut ist, also bei normalem oder nur gering erhöhtem Wasserstand.Basically, it is possible to reduce the risk of populated areas with dams and dikes of appropriate height or completely off. However, the boundaries between the water from which the hazard originates and the vulnerable zones in many cases run straight in populated areas, so that obstructing such dams and dykes does not meet with the acceptance required for safety. In most cases, it is also desired or required that the structural measures do not or only slightly disturbing, if the threat is not acute, so at normal or only slightly increased water level.

Seit langem ist es bekannt, mit baulichen Massnahmen Schutzzonen gegen Überschwemmungen zu schaffen, wobei die Schutzelemente ohne akute Gefährdung ganz oder teilweise abgesenkt werden können. Dabei gibt es grundsätzlich verschiedene Schutzmöglichkeiten, wie das vertikale Ausfahren von Schutzwänden oder das Hochklappen von Schutzelementen, wobei - je nach den baulichen und bedrohungsseitigen Rahmenbedingungen - einer der Möglichkeiten der Vorzug zu geben ist.For a long time, it has been known to create protection zones against floods with structural measures, whereby the protective elements can be completely or partially lowered without acute danger. There are basically various protection options, such as the vertical extension of protective walls or the folding of protective elements, depending on the constructional and threat-related conditions one of the possibilities should be preferred.

Aus der DE-195 14 205 A1 ist z.B. eine bauliche Massnahme mit klappbaren Elementen bekannt, bei der eine Aufnahmekammer einerseits eine flutbare Schwimmkammer und andererseits eine Einschwenkkammer umfasst und das Schwenkelement aus der Horizontalen in die Vertikale geschwenkt wird. Die dort beschriebene bauliche Massnahme basiert auf der Grundidee, das Ausschwenken durch das Aufschwimmen der als Pontonteile ausgebildeten Schutzwand in der Schwimmkammer zu bewirken oder zumindest zu unterstützen. Dies hat sich aber nicht als vorteilhaft herausgestellt. Weiterhin soll die Fläche der Schutzelemente zu den Zeitpunkten, in denen keine akute Gefährdung stattfindet, für andere Zwecke genutzt werden, wie z.B. als Fusswege, als Fahrwege etc.From the DE-195 14 205 A1 For example, a structural measure with hinged elements is known, in which a receiving chamber on the one hand, a floodable swimming chamber and on the other hand, a Einschwenkkammer includes and the pivoting element is pivoted from the horizontal to the vertical. The structural measure described there is based on the basic idea of causing or at least supporting the swiveling out by the floating of the protective wall designed as a pontoon part in the floating chamber. However, this has not turned out to be advantageous. Furthermore, the surface of the protective elements should be used for other purposes at those times when there is no acute danger, such as footpaths, driveways, etc.

Aus der WO 99/24675 A1 ist ein Hochwasserschutz bekannt, bei dem auf die Schwimmkammer bereits verzichtet werden kann und bei dem mit Hilfe einer Antriebseinrichtung die Schutzstellung im aufgeklappten Zustand oder die Ruhestellung eingenommen werden kann. Im aufgeklappten Zustand wird dabei ein Teil der Klappwand in einen Kanalunterbau abgesenkt. In der WO 99/24675 A1 wird dabei vorgeschlagen, die Antriebseinrichtung im oder am Drehlager wirksam werden zu lassen.From the WO 99/24675 A1 a flood protection is known in which the floating chamber can already be dispensed with and in which by means of a drive means the protective position in the unfolded state or the rest position can be taken. In the unfolded state while a part of the flap wall is lowered into a channel substructure. In the WO 99/24675 A1 It is proposed that the drive device be effective in or on the pivot bearing.

Aus dem deutschen Gebrauchsmuster DE-202 04 097 U1 ist ein aus der WO 99/24675 A1 weiterentwickelter Hochwasserschutz mit klappbaren Elementen bekannt, der ebenso einen Kanal zum Absenken eines Teils der Klappelemente und zur Aufnahme der Antriebselemente aufweist.From the German utility model DE-202 04 097 U1 is one of the WO 99/24675 A1 advanced flood protection with hinged elements known, which also has a channel for lowering a portion of the folding elements and for receiving the drive elements.

Bei einer Abschätzung der Durchführbarkeit von solchen permanenten Hochwasserschutzsystemen hat sich nun ergeben, dass der Aufwand - und damit die Kosten - für einen solchen Hochwasserschutz so erheblich sein kann, dass eine planmässige Verbauung insbesondere über eine grössere Schutzlänge nicht realisiert werden kann. Damit wird der Wert der vorstehend diskutierten Schutzsysteme nicht in Frage gestellt, lediglich bei längeren Verbauungslinien sind auch Alternativen permanenter Hochwasserschutzverbauung mit beweglichen, in Ruhestellung nicht störenden Schutzelementen zu suchen.In an estimation of the feasibility of such permanent flood protection systems has now shown that the cost - and thus the cost - for such a flood protection can be so significant that a planned obstruction can not be realized in particular over a longer protection length. Thus, the value of the above-discussed protection systems is not questioned, only for longer Verbauungslinien are also alternatives permanent flood protection with movable, at rest not disturbing protective elements to look for.

Weiterhin wird von dem durch die vorliegende Erfindung vorgeschlagenen Hochwasserschutzsystem verlangt werden müssen, dass eine Verbauung einfach und schnell ausgeführt werden können muss und dass das "Aufrichten" der Schutzelemente mit einfachen Mitteln durchgeführt werden kann.Furthermore, from the flood protection system proposed by the present invention, it must be required that an obstruction can be easily and quickly carried out and that the "erection" of the protective elements can be carried out by simple means.

In der DE-A-102 40 687 ist eine Schutzanlage für den Einsatz bei Hochwasser vorgeschlagen worden, bei der die nebeneinander zu verlegenden Elemente jeweils aus einem geneigten Schild und einem horizontalen Schild bestehen, die durch Gelenke verbunden sind. Die Neigung des geneigten Schildes wird dabei durch eine Stütze bewirkt, die am Ende des horizontalen Schildes durch ein Gelenk befestigt ist und das geneigte Schild mit Hilfe eines Elementes aus einem Winkeleisen stützt. Dieser Vorschlag bildet gemäss der vorliegenden Erfindung den nächstliegenden Stand der Technik und ist deshalb im Oberbegriff von Anspruch 1 reflektiert.In the DE-A-102 40 687 a flood protection system has been proposed, in which the elements to be laid side by side each consist of an inclined shield and a horizontal shield, which are connected by joints. The inclination of the inclined shield is effected by a support which is fixed at the end of the horizontal shield by a hinge and supports the inclined shield by means of an element of an angle iron. This proposal forms the closest prior art according to the present invention and is therefore reflected in the preamble of claim 1.

Als weiteres Problem hat sich herausgestellt, dass die eingesetzten Schutzelemente im Boden so gut verankert sein müssen, dass sie auch bei einem Anschwellen des Grundwasserpegels fest in ihrer Verankerung verbleiben. Insbesondere ist es wünschenswert, dass im eingeklappten Zustand des Hochwasserschutzsystems die Verbauungslinie strassenartig befahrbar sein soll. Bei der Verlegung sind weiterhin Massnahmen vorzusehen, die ein Einfrieren durch Regenwasser und damit ein ungestörtes Aufklappen auch in einem solchen Zustand verhindern. Wie sich herausgestellt hat, sind diese Aufgaben mit der DE-A-102 40 687 noch nicht gelöst.Another problem has been found that the protective elements used must be anchored so well in the ground that they remain firmly in their anchorage even with a swelling of the groundwater level. Especially It is desirable that in the collapsed state of the flood protection system, the construction line should be road-like passable. When laying, further measures must be taken to prevent freezing by rainwater and thus undisturbed unfolding even in such a condition. As it turns out, these tasks are with the DE-A-102 40 687 not yet solved.

Die vorstehend beschriebenen Probleme mit den bestehenden, zuvor vorgeschlagenen Hochwasserschutzsystemen gilt es also durch die vorliegende Erfindung zu lösen.The above-described problems with the existing, previously proposed flood protection systems, it is therefore to be solved by the present invention.

Die Erfindung löst die Aufgabe durch einen Hochwasserschutz nach Anspruch 1 und ein Verfahren nach Anspruch 16. Dabei haben die Massnahmen der Erfindung zunächst einmal zur Folge, dass die Grundplatten gegeneinander abgedichtet sind und dass eine relativ einfache und wenig aufwendige Konstruktion standardisiert implementiert werden kann, ohne dass an den Schutzanforderungen gegenüber der Hochwasserbedrohung irgendwelche Abstriche gemacht werden müssten. Als weiteres haben die Massnahmen der Erfindung zur Folge, dass auf ein eigenes, allenfalls anfälliges Antriebssystem für das Aufrichten der Schutzelemente verzichtet werden kann, ohne dass dabei ein hoher händischer Aufwand notwendig wird. Dazu tragen die Massnahmen der Erfindung in ihrer Kombination bei. Durch die spezielle Art des Zusammenspiels der Elemente ist insbesondere berücksichtigt, dass ein Festfrieren der Elemente durch eingedrungenes Regenwasser etc. ein sicheres Öffnen verhindert. Bei einer entsprechenden Auslegung der Dicke der Elemente ist zudem ein sicheres Befahren ohne Beschädigung der Elemente im eingeklappten Zustand möglich, da - im Gegensatz zu der in der DE-A-102 40 687 vorgeschlagenen Lösung - eine sich berührende Klappfläche gewährleistet werden kann.The invention solves the problem by a flood protection according to claim 1 and a method according to claim 16. The measures of the invention initially have the consequence that the base plates are sealed against each other and that a relatively simple and inexpensive construction can be implemented standardized, without that the protection requirements against the flood threat would have to be compromised. Another consequence of the measures of the invention is that it is possible to dispense with a separate, at most, vulnerable drive system for erecting the protective elements, without necessitating a high level of manual effort. Contribute to the measures of the invention in their combination. Due to the special nature of the interaction of the elements is taken into account in particular that a freezing of the elements by penetrating rainwater etc. prevents safe opening. With a corresponding design of the thickness of the elements safe driving is also possible without damaging the elements in the folded state, since - in contrast to the in the DE-A-102 40 687 proposed solution - a touching flap surface can be ensured.

Das Hochwasserschutzsystem umfasst eine Vielzahl von Schutzelementen, die jeweils zumindest eine erste, schwenkbare Schutzplatte zur Ausbildung einer Schutzwand in einem in eine Schrägstellung geschwenkten Zustand und zur Ausbildung einer im wesentlichen ebenen Fläche in einem horizontalen, schutzwirkungsfreien Zustand, eine zweite, in etwa waagerecht am Boden festinstallierte Grundplatte, zumindest zwei Stützmittel - vorzugsweise Schwerlastdeckenstützen mit Kopfplatten - zum Abstützen der Schutzplatten in der in Schrägstellung geschwenktem Zustand, Dichtmittel zum Abdichten der Schutzplatte gegen die Grundplatte und zum Abdichten von zwei nebeneinander angeordneten Schutzplatten gegeneinander, nämlich Dichtbänder, die ohne Reibungsfläche eingesetzt werden können. Die Dichtmittel wirken dann dichtend, wenn sich die Schutzplatten in aufgeschwenkten Schutzzustand befinden.The flood protection system comprises a plurality of protective elements, each at least a first, pivotable protective plate for forming a protective wall in a tilted state in an inclined position and to form a substantially flat surface in a horizontal, Schutzwirkungsfreien state, a second, approximately horizontally on the ground fixed base plate, at least two support means - preferably heavy duty ceiling supports with top plates - For supporting the protective plates in the swung in inclined state, sealing means for sealing the protective plate against the base plate and for sealing two juxtaposed protective plates against each other, namely sealing tapes that can be used without friction surface. The sealing means then act sealing when the protective plates are in the swung-open protective state.

Nicht unterschätzt werden sollte das Merkmal, dass die Schutzplatten überlappende Fugen aufweisen, die dann beim Wasseranstau durch den Wasserdruck verstärkend abdichten.It should not be underestimated that the protective panels have overlapping joints which then reinforce the water accumulation by the water pressure.

Weiterhin nicht unterschätzt werden sollte das Merkmal, dass die Grundplatten unten jeweils zu der Seite der benachbarten Grundplatte angefast sind, da sie so zuverlässig mit minimalem Abstand durch den Einsatz von Hilfsmitteln (z.B. Hubstaplern) verlegt werden können.Further, it should not be underestimated that the base plates are chamfered down to the side of the adjacent base plate, respectively, because they can be reliably relocated with minimum clearance through the use of tools (e.g., lift trucks).

An der hinteren Seite, die beim Einbau der Wasserseite entspricht, bildet das Abschlussfundament 220 zu den Plattenseiten hin einen Kanal aus, um ein problemloses Schwenken der Schutzplatte 20 zu ermöglichen.The designated in Figure 1 as a whole with 100 flood protection system consists of a bottom element as applied to an L-shaped reinforced concrete foundation 60 base plate 30 and to the base plate 30 made of reinforced concrete with a hinge 40 pivotally mounted protective plate 20 - also made of reinforced concrete. On the front side, which corresponds to the installation of the dry side, a final foundation 210 is to see, usually a road or building completion. At the rear side, which corresponds to the installation of the water side, the end foundation 220 forms a channel towards the side of the plate to allow a smooth pivoting of the protective plate 20.

In der Bodenplatte 30 sind Verankerungsbohrungen 36 - im vorliegenden Ausführungsbeispiel weist jede Grundplatte 30 vier Verankerungsbohrungen auf - zu sehen, mit denen die Grundplatte 30 am - im vorliegenden Ausführungsbeispiel L-förmigen - Stahlbetonfundament 60 mit Hilfe von Verbundankern befestigt ist. In Figur 2 sind die im vorliegenden Ausführungsbeispiel verwendeten Schutzplatten 20 zu sehen.In the bottom plate 30 are anchoring holes 36 - in the present embodiment, each base plate 30 has four anchoring holes - to see, with which the base plate 30 on - in the present embodiment, L-shaped - reinforced concrete foundation 60 is fixed by means of composite anchors. FIG. 2 shows the protective plates 20 used in the present exemplary embodiment.

In Figur 3 sind entsprechend die nebeneinander angeordneten Grundplatten 30 dargestellt, die untereinander mit einer Vergussbetonmasse 72 abgedichtet sind. Die Vergussbetonmasse 72 hat dabei ein E-Modul, das so ausgewählt ist, dass die Ausbetonierung erfolgt, ohne dass Schwindrisse auftreten. Die Vergussbetonmasse wird dabei in einen Bereich eingefüllt, die durch Aussparungen jeweils an den Rändern der Grundplatten 30 ausgebildet sind und in die hinein Anschlussarmierungsbügel stehen, die sich nach der fertigen Montage der Elemente gegenseitig überlappen. In Querrichtung der Betonelemente werden so genannte Verteilungseisen eingesetzt bevor die Ausbetonierung mit dem speziellen Vergussbeton mit Dichtungszusatz vorgenommen wird.In Figure 3, the side by side arranged base plates 30 are shown, which are sealed with each other with a Vergussbetonmasse 72. The grouting concrete mass 72 has an E-modulus which is selected such that the concreting takes place without shrinkage cracks occurring. The Vergussbetonmasse is thereby filled in an area which are formed by recesses respectively at the edges of the base plates 30 and in which are Anschlussarmierungsbügel, which overlap each other after the finished assembly of the elements. In the transverse direction of the concrete elements so-called distribution iron are used before the concreting is carried out with the special grouting concrete with sealing additive.

Figur 4 zeigt die Scharniereinrichtung 40 für die Schwenkbewegung der Schutzplatte 20 gegen die Grundplatte 30. Es hat sich herausgestellt, dass für eine Platte mit einer Länge von 6 m (bezogen auf die Bodenplatte 30) zwei Chromstahlscharniere mit einer Länge von 150 mm und einer Dicke von 20 mm ausreichen. Im Ausführungsbeispiel sind - besonders vorteilhaft - Verankerungsplatten 42 und 43 mit einer Dicke von 20 mm und einer Tiefe von typischerweise 70 bis 120 mm - im Ausführungsbeispiel von 90 mm - in die Schutzplatte 20 bzw. in die Grundplatte 30 in einem Winkel von ca. 45° eingearbeitet. Wie auch aus der Figur 4 hervorgeht, sind die beiden Platten 20 und 30 mit einem Winkel von ca. 30° und einer Tiefe von ca. 370 mm angefast, um einen Öffnungsbereich für das Öffnen des Scharniers und damit des Aufschwenkens der Schutzplatte 20 zu ermöglichen. In diesem angefasten Bereich, im beschriebenen Ausführungsbeispiel in etwa in der Mitte, sind sowohl an der Grundplatte 30 wie auch an der Schutzplatte 20 über die gesamte Länge der Platten Dichtbänder 70 angeordnet. Dieser Zusammenhang geht auch aus Fig. 10 hervor.Figure 4 shows the hinge means 40 for the pivotal movement of the protective plate 20 against the base plate 30. It has been found that for a plate with a length of 6 m (relative to the bottom plate 30) two chrome steel hinges with a length of 150 mm and a thickness of 20 mm suffice. In the exemplary embodiment are - particularly advantageous - anchoring plates 42 and 43 with a thickness of 20 mm and a depth of typically 70 to 120 mm - in the embodiment of 90 mm - in the protective plate 20 and in the base plate 30 at an angle of about 45 ° incorporated. As can also be seen from FIG. 4, the two plates 20 and 30 are chamfered at an angle of approximately 30 ° and a depth of approximately 370 mm in order to allow an opening region for the opening of the hinge and thus the swiveling up of the protective plate 20 , In this chamfered region, in the described embodiment, approximately in the middle, sealing strips 70 are arranged both on the base plate 30 and on the protective plate 20 over the entire length of the plates. This relationship is also apparent from Fig. 10.

In Figur 5 ist die Ausgestaltung der Stützenauflager 52 dargestellt. Die Stützenauflager 52 weisen seitlich eine Halterung 58 auf, in die die Kopfplatten 56 der Schwerlastdeckenstützen 50 eingeschoben werden. Im vorliegenden Ausführungsbeispiel sind Schwerlastdeckenstützen nach DIN 4424 vorgesehen, um allenfalls ein Standardteil verwenden zu können. Die Stützenauflager 52 sind in den Schutzplatten 20 wie auch in den Bodenplatten 30 mit Hilfe der Kopfbolzendübel 54 verankert und weisen im vorliegenden Ausführungsbeispiel einen Winkel von 30° bis 45° gegenüber der Plattenoberfläche auf, damit sie die Kopfplatten 56 der Schwerlastdeckenstützen 50 eben abstützen können.FIG. 5 shows the configuration of the support supports 52. The support supports 52 have laterally a holder 58 into which the top plates 56 of the heavy-duty ceiling supports 50 are inserted. In the present embodiment, heavy-duty ceiling supports according to DIN 4424 are provided in order to use a standard part if necessary. The support supports 52 are anchored in the protective plates 20 as well as in the bottom plates 30 by means of the head bolt dowels 54 and have in the present embodiment at an angle of 30 ° to 45 ° relative to the plate surface so that they can support the top plates 56 of the heavy duty ceiling supports 50 just.

Im vorliegenden Ausführungsbeispiel sind in den Bodenplatten 30 Aussparungen zur Aufnahme der Schwerlastdeckenstützen 50 im Ruhezustand des Hochwasserschutzsystems vorgesehen.In the present embodiment 30 recesses for receiving the heavy duty ceiling supports 50 are provided in the resting state of the flood protection system in the bottom plates.

Aus den vorstehend beschriebenen geometrischen Verhältnissen ergibt sich der besonders vorteilhafte Schutzmechanismus des erfindungsgemässen Hochwasserschutzsystems, bei dem nämlich ein Aufschwenken der Schutzplatte 20 um ca. 60° vorgesehen ist. Falls dieser Winkel abgeändert werden soll, muss - neben der Länge der nachstehend beschriebenen. Stützen 50 und der Einbauanordnung - dazu der Winkel der Anfasung der beiden Platten 20 und 30 geändert werden. Allerdings hat sich herausgestellt, dass ein Aufschwenken der Schutzplatten 20 um 55° bis 65°, vorzugsweise in etwa 60° die besten statischen Verhältnisse ermöglicht.From the geometric conditions described above, the particularly advantageous protective mechanism of the flood protection system according to the invention results, in which a pivoting of the protective plate 20 is provided by about 60 °. If this angle is to be changed, it must - in addition to the length described below. Supports 50 and the mounting arrangement - to the angle of the chamfering of the two plates 20 and 30 are changed. However, it has been found that a pivoting of the protective plates 20 by 55 ° to 65 °, preferably in about 60 ° allows the best static conditions.

Das Aufrichten der Schutzplatten 20 ist gemäss der vorliegenden Erfindung mit Hilfe einer Hebeeinrichtung (Schwenkkran) vorgesehen, die die einzelnen Schutzplatten 20 des Hochwasserschutzsystems nacheinander aufrichtet und somit einen Schutzwall herstellt. Im vorliegenden Ausführungsbeispiel müssen selbstverständlich die Schutzplatten 20 mit der oben ausgebildeten Verbreiterung jeweils zuerst aufgerichtet werden. Grundsätzlich ist für das hier beschriebene Hochwasserschutzsystem auch ein händisches Aufrichten der Schutzplatten 20 möglich, allerdings erfordert dies einen Einsatz von einigen Personen. Nach dem Aufrichten der Schutzplatten 20 werden sodann jeweils zwei der vorstehend beschriebenen Schwerlastdeckenstützen 50 pro Schutzplatte 20 in die Halterung für die Kopfplatten eingeschoben und können allenfalls noch durch ein Sicherungselement (Befestigungsmittel wie Schraubbolzen, Splint oder ähnliches) gesichert werden.The erecting of the protective plates 20 is provided according to the present invention by means of a lifting device (jib crane), which raises the individual protective plates 20 of the flood protection system successively and thus produces a protective barrier. In the present embodiment, of course, the protective plates 20 with the widening formed above each be raised first. Basically, a manual erection of the protective plates 20 is possible for the flood protection system described here, but this requires the use of some people. After erecting the protective plates 20 then two of the heavy-load ceiling supports 50 described above per protective plate 20 are then inserted into the holder for the top plates and can at best even by a securing element (fasteners such as bolts, cotter pin or the like) are secured.

Im Weiteren wird beschrieben, wie die Hochwaaserechutzelemente seitlich an bestehende Bauten etc. angeschlossen werden können. Dabei werden die Bauten zum Beispiel mit Einrichtungen versehen, die den Fugendichtungen zwischen den einzelnen Schutzplatten 20 entsprechen bzw. gleichwirkend sind. Dies kann durch schräge Vorsprünge wie bei den Schutzplatten 20 bewirkt werden. Möglich und vorgesehen ist es aber auch, dass die schräg aufgerichteten Schutzplatten nach dem Aufrichten temporär dichtend mit den entsprechenden Bauten verbunden werden, z.B. durch Metallwinkel etc. Dazu sind dann Gewindeelemente in den äusseren Schutzplatten 20 vorgesehen, um solche Winkel an den Schutzplatten dichtend zu befestigen.In the following, it will be described how the high-wave protective elements can be connected laterally to existing buildings, etc. The buildings are provided, for example, with facilities that correspond to the joint seals between the individual protective plates 20 and are equally effective. This can be effected by oblique projections as in the protective plates 20. However, it is also possible and provided for the obliquely erected protective plates to be temporarily sealed to the corresponding structures after erection, e.g. by metal angles, etc. For this purpose, threaded elements are then provided in the outer protective plates 20 in order to sealably secure such angles to the protective plates.

Bei einer Richtungsänderung der Verbauungslinie des Hochwasserschutzsystems gemäss dem hier beschriebenen Ausführungsbeispiel der vorliegenden Erfindung ist vorgesehen, an Stelle der Grundplatten ein der Liegehöhe der Schutzplatte entsprechendes Fundament, z.B. mit dem vorgesehenen Winkel der Richtungsänderung, bereitzustellen. Weiterhin ist für ein solches Teilstück vorgesehen, mit vorgefertigten, entsprechend der Änderung der Verbauungslinie geformten Blechplatten die entsprechende Schutzlücke zu schliessen. Solche Blechplatten werden, wie oben für die Metallwinkel beschrieben, an die aufgerichteten Schutzplatten angeschraubt.In a change in direction of the line of construction of the flood protection system according to the embodiment of the present invention described here is provided instead of the base plates of the deck height of the protective plate corresponding foundation, for example, with the intended angle of change in direction to provide. Furthermore, it is provided for such a section to close with prefabricated, according to the change in the obstruction line shaped sheet metal plates the corresponding protection gap. Such metal plates are, as above for the metal angle described screwed to the erected protective plates.
