Description
Deichbefestigung aus Spundbohlen zur Verstärkung von vorhandenen und neuen DeichenDyke reinforcement using sheet piles to reinforce existing and new dykes
An Küsten, Seen und Flüssen werden zur Zurückhaltung des Wassers Deiche errichtet, um bei erhöhten Wasserständen eine Überflutung des angrenzenden Landes zu verhindern. Die Form der Deiche ist in der Regel so gewählt, daß sie den Seitenkräften des steigenden Hochwassers standhalten können.Dikes are built on coasts, lakes and rivers to hold back water and prevent flooding of the adjacent land when water levels rise. The shape of the dikes is usually chosen so that they can withstand the lateral forces of the rising flood water.
Infolge von Verschwächungen des Deichkörpers, hervorgerufenAs a result of weakening of the dyke body, caused
a) durch mechanische Einwirkungen an den Deichoberflächen oder innerhalb des Deiches durch Aktivitäten von Tieren (Kaninchen, Maulwürfe, usw.),a) through mechanical impacts on the dike surfaces or within the dike through activities of animals (rabbits, moles, etc.),
b) durch Erosion infolge des Angriffs starker Strömungen des Wassers, oderb) by erosion resulting from the attack of strong water currents, or
c) durch die Wirkung von Auftriebskräften auf das Deichmaterial bei zunehmender Durchweichung mit eindringendem Wasserc) due to the effect of buoyancy forces on the dyke material as it becomes increasingly soggy with penetrating water
kommt es bei extremen Hochwasserpegeln zu Durchbrüchen, da die vorhandene Deichmasse den Horizontalkräften des Wassers nicht mehr ausreichend entgegenwirkt.Extreme flood levels can lead to breaches because the existing dike mass no longer adequately counteracts the horizontal forces of the water.
Der im Schutzanspruch 1 angegebenen Erfindung liegt das Problem zugrunde, die vorhandenen, nach Durchbrüchen auszubessernden oder gänzlich neu zu errichtenden Deiche so zu verstärken, daß der bei Hochwasser auftretende Wasserdruck und das in den Deich eindringende Wasser den Deich nicht mehr so erheblich schwächen können, daß es zu einem Bruch kommt.The invention specified in claim 1 is based on the problem of strengthening the existing dikes that are to be repaired after breaches or completely rebuilt in such a way that the water pressure that occurs during flooding and the water penetrating the dike can no longer weaken the dike so significantly that it breaks.
Dieses Problem wird mit dem in Schutzanspruch 1 beschriebenen Merkmalen, das vertikale Einsetzen von ineinandergreifenden Spundbohlen, gelöst.This problem is solved with the features described in claim 1, the vertical insertion of interlocking sheet piles.
Mit der Erfindung wird erreicht, daß infolge der Abdichtung durch die ineinandergreifenden Spundbohlen das weitere Eindringen von Wasser verhindert und insbesondere durch den Kraftschluß der eingebrachten Spundbohlen eine horizontale Verschiebung des Deichkörpers aufgehalten wird. Damit werden entscheidende Verschwächungen des Deiches vermieden.The invention ensures that the sealing by the interlocking sheet piles prevents further water penetration and, in particular, the frictional connection of the sheet piles prevents horizontal displacement of the dyke body. This prevents significant weakening of the dyke.
Eine weitere vorteilhafte Ausgestaltung ist im Schutzanspruch 2 angegeben.A further advantageous embodiment is specified in claim 2.
Dadurch daß die Spundbohlen jeweils unabhängig voneinander bis in den festen, gewachsenen Untergrund eingesetzt werden können, werden die vom Wasserdruck der ansteigenden Flut stammenden Horizontalkräfte und das dadurch eingebrachte Biegemoment durch die feste Einspannung in den Boden weitgehend aufgenommen und nicht mehr in vollem Umfange in den sich landwärts anschließenden Teil des Deiches eingeleitet.Because the sheet piles can be inserted independently of one another into the solid, natural subsoil, the horizontal forces resulting from the water pressure of the rising tide and the bending moment introduced as a result are largely absorbed by the firm clamping into the ground and are no longer fully introduced into the part of the dike adjoining the landward side.
Die in Schutzanspruch 3 angegebenen mit einer Perforation versehenen Spundbohlen geben dem Deich die im Schutzanspruch 2 genannte höhere Festigkeit gegenüber dem Hochwasser und erlauben gleichzeitig den Austausch des Grundwassers im Bereich der Perforation, sofern dies gefordert ist.The sheet piles provided with a perforation specified in claim 3 give the dyke the higher resistance to flooding specified in claim 2 and at the same time allow the exchange of groundwater in the area of the perforation, if this is required.
Infolge der in Schutzanspruch 4 beschriebenen Lösung, daß die Spundbohlen unsichtbar unterhalb der Deichkrone abschließen, bleibt das Bild der Küsten-, Fluß- oder sonstigen Deichlandschaft erhalten und wird nicht durch herausragende Enden von Spundbohlen beeinträchtigt.As a result of the solution described in claim 4, whereby the sheet piles end invisibly below the top of the dike, the image of the coastal, river or other dike landscape is preserved and is not impaired by protruding ends of sheet piles.
Die in Schutzanspruch 5 angegebene Nachrüstung weiterer Bohlen erlaubt es, bei drohendem Wasseranstieg über die Deichkrone hinaus sehr schnell und zu geringen Kosten einen zusätzlichen Schutz vor dem Übertritt des Wassers zu erhalten. Beim Absinken des Pegels können die nachgerüsteten Spundbohlen wieder entfernt werden.The retrofitting of additional sheet piles specified in claim 5 makes it possible to obtain additional protection against water overflow very quickly and at low cost if the water level is threatening to rise above the crest of the dyke. If the water level drops, the retrofitted sheet piles can be removed again.
Durch die in Schutzanspruch 6 angegebene versetzte Anordnung der Spundbohlen können bei der gewünschten Deicherhöhung die aufzusetzende Bohlen sehr leicht in die vorhandenen freien Lücken eingesetzt werden. Danach können die noch offenen Zwischenräume durch das Einschieben weitere Bohlen geschlossen werden.Due to the staggered arrangement of the sheet piles specified in claim 6, the piles to be added can be very easily inserted into the existing free gaps when the dyke is raised to the desired level. The gaps that are still open can then be closed by inserting further piles.
Ein Ausfuhrungsbeispiel der Erfindung wird anhand der Fig. 1 bis 5 erläutert.An embodiment of the invention is explained with reference to Figs. 1 to 5.
In Fig. 1 ist im Querschnitt eines Deichkörpers 2 eine Reihe von Spundbohlen 1 einsetzt, die mit Schlössern ineinandergreifen und in den festen Boden abgesenkt sind.In Fig. 1, a row of sheet piles 1 is inserted in the cross-section of a dyke body 2, which interlock with locks and are sunk into the solid ground.
In Fig. 2 ist beispielhaft bei 5 die Anordnung der Spundbohlen 1 bei unterschiedlicher Tiefe des festen Untergrundes 6 gezeigt.In Fig. 2, the arrangement of the sheet piles 1 at different depths of the solid subsoil 6 is shown as an example at 5.
Die Perforierung 7 der Spundbohlen 1 in dem Bereich des festen Bodens 6 ist in Fig. 3 gezeigt.The perforation 7 of the sheet piles 1 in the area of the solid ground 6 is shown in Fig. 3.
Das Ineinandergreifen der Profile der Spundbohlen 1 mittels Schlössern 8 ist im Querschnitt in Fig. 4 dargestellt.The interlocking of the profiles of the sheet piles 1 by means of locks 8 is shown in cross section in Fig. 4.
In Fig. 5 ist die versetzte Anordnung im oberen Bereich 9 der in einen Deich eingesetzten Spundbohlen 1 zu erkennen. Weitere Spundbohlen 1 können zur Erhöhung des Deiches aufgrund der versetzten Anordnung leicht aufgesetzt werden.In Fig. 5, the staggered arrangement in the upper area 9 of the sheet piles 1 inserted into a dyke can be seen. Additional sheet piles 1 can easily be added to raise the dyke due to the staggered arrangement.
