Definitions
- the invention relates to a geotextile sand container for underwater protection of buildings, in particular as Kolkschutz with a geotextile shell and a sand filling. Furthermore, the invention relates to a method for lowering geotextile sand containers, wherein the sand container is positioned on the water surface and released, so that it sinks to the seabed.
- Such geotextile sand containers are known in coastal protection in a variety of arrangement and application and different sizes. Exemplary is a publication at HCU Symposium Geoa for the coastal zone of 07. October 2010 "Geotextile Sand Containers in Coastal Protection” by Matthias Bleck, Uwe Momsen and Michael Schöner The KED engineers Knabe Enders D versatilekop Engineers GmbH referenced. From this, the use of geotextile sand containers as Kolkschutz to foundation structures, such as monopiles known.
- any submerged underwater structure interferes with the dynamic balance between the body of water and the mobile seabed.
- the US 2009/0 208 288 A1 describes a flexible, water-permeable tube made of a geotextile for receiving a filling material, wherein the tube spans at its two opposite ends after receiving the filler flat plane end faces, so that in the longitudinal direction joined together such sand tubes result in a seamless transition. It is thus avoided that ocean currents can attack at adjacent ends of the sand tubes.
- ballast According to the sand container is placed with its in installation position down, ballast mandat section on the water surface, immersed and released in this orientation, in the sinking the container holds by the ballast its relative orientation in the water body and decreases according to its relative weight in the water and its flow resistance in Essentially straightforward to the seabed.
- the flow around the sand container when sinking can be optimized by the fact that the geotextile shell has formed in its in-mounting position below section a tip, convex protrusion or three-sided prism. This flow optimization further stabilizes the sinking behavior and increases the sinking rate.
- the known cushion shape of the geotextile sand container can be maintained, the installation position with its largest cross-section flat oriented on the seabed.
- a sinking with its largest cross-section oriented normal to Absinkraum represents a stable position in the water, which is a substantially straight-line sinking.
- the sinking process is relatively slow, since the flow resistance around the pillow is relatively high. Accordingly, there is a higher risk of dripping with larger water depths and / or stronger ocean currents.
- hydrodynamic guide vanes are formed on the longitudinal sides of the sand container oriented in the installation position.
- This guide wings stabilize the sinking of the ballasted sand container, especially at a faster sinking speed, which is made possible by a hydrodynamically optimized shaping of the sand container, for example in the manner of a torpedo armature.
- the guide vanes are formed from the geotextile of the shell, as there are thus no further different materials to be provided on the sand container and damage to adjacent and / or passing sand containers are avoided.
- the flow resistance in the water body in the sinking direction decreases significantly, preferably together with the features of subclaim 2, so that the sinking rate increases.
- the sand container to be lowered is released spontaneously without transmitting motion impulses to the sand container.
- the sand container at the moment of letting go in the body of water still receives a change in orientation and thus does not meet its actual destination on the seabed with sufficient accuracy.
- the storage target on the seabed for the sand container can be precisely reached by providing calculated hold even with relatively slowly sinking sand containers (pillow containers) or with very strong ocean currents ,
- Fig. 1 shows a sand container 1 with a possible elongated shape with a geotextile sheath 10 and a sand filling 2 received therein.
- a lying in installation position portion 11 of the sand container 1 is ballasted by that therein heavier material 21, for example with water saturated sand or gravel is filled.
- dry sand 22 is filled. This can be achieved, for example, with a sand container completely filled with dry sand, which is in a proper orientation in a water bath prior to installation, which leads to ballast (water saturation) of the lower, standing in the water part of the sand container.
- FIG. 2 Alternatively to in FIG. 1 shown vertically elongated shape of the sand container 1 is in FIG. 2 a similarly shaped sand container 1 shown, the lying in the installed position section 11, however, along a long side of the sand container 1 is arranged.
- FIG. 3 a cylindrical sand container 1 is shown, which has a downwardly tapered conical shape in its lower position in the mounting position 11 in the shell 10, so that this sand container 1 sinks during the sinking process through the ballast and the flow-technically meaningful cone shape to the cylinder axis of the sand container.
- a sand container 1 shown which in turn has a cylindrical basic shape, but in addition to the ballasting of a lying in position below section 11 by heavy material 21, for example water saturated sand and / or gravel four wings 15 on its formed in Zylindermantelform longitudinal side.
- heavy material 21 for example water saturated sand and / or gravel four wings 15 on its formed in Zylindermantelform longitudinal side.
- the wings 15 stabilize the trajectory of the sand container 1.
- the wings 15 are the stronger, the higher the relative speed (descent) of the sand container 1 in the water body.
- a sand container 1 has a substantially cylindrical shell 10, but in which the underlying section 11 has a conical tip 13 which is ballasted. Further points this embodiment, the attached on the cylinder jacket-shaped longitudinal side wings 15. In a sinking movement in the direction of the cylinder axis 14, the water is displaced centering in the Absink Gay and stabilized by the relative movement in the body of water along the wings 15, the Absinkière.
- the upper end of the sand container tapers, so that a further reduction of the hydraulic resistance is achieved in the sinking of the sand container. Accordingly, the sand container thus formed reaches a relatively high sinking speed, similar to torpedo anchors known.

Derartige geotextile Sandcontainer sind im Küstenschutz in vielfältiger Anordnung und Anwendung und unterschiedlichen Größen bekannt. Beispielhaft wird auf eine Veröffentlichung bei HCU Symposium Geoinformationen für die Küstenzone
Grundsätzlich gilt, dass jede Gründungsstruktur unter Wasser bei einer Umströmung das dynamische Gleichgewicht zwischen dem Wasserkörper und dem mobilen Meeresboden stört. Durch Wechselwirkungen zwischen der Gründungsstruktur, den hydrodynamischen Belastungen und dem beispielsweise aus mehr oder weniger dicht gelagerten Sanden bestehenden Meeresboden entstehen Erosions- und Sedimentationsvorgänge im Nahbereich des Bauwerkes sowie Auflockerungen des Meeresbodens in größerer Umgebung. Dabei gefährden insbesondere Sohlveränderungen im Nahbereich, die sog. Kolkbildung die Standsicherheit der Gründungsstruktur bzw. des Bauwerkes. Es gilt daher geeignete Kolkschutzmaßnahmen vorzusehen. Hierzu gibt es Untersuchungen und Veröffentlichungen, die sich insbesondere mit dem Kolkschutz für die Gründung von Offshore-Windenergieanlagen beschäftigen, wie in der
Die
In der Veröffentlichung im Tagungsband des 8. FZK-Kolloquiums "
Ausgehend von diesem Stand der Technik ist es Aufgabe der Erfindung, einen geotextilen Sandcontainer so auszubilden, dass er eine weitestgehend gleichmäßige Absinkbewegung durch den Wasserkörper vollführt und in einer vorbestimmbaren Orientierung den Meeresboden erreicht.Based on this prior art, it is an object of the invention to form a geotextile sand container so that it largely as possible performs uniform Absinkbewegung by the body of water and reaches the seabed in a predeterminable orientation.
Gelöst wird diese Aufgabe mit einem geotextilen Sandcontainer mit den Merkmalen von Patentanspruch 1 sowie einem Verfahren gemäß Anspruch 8.This object is achieved with a geotextile sand container having the features of patent claim 1 and a method according to claim 8.
Dadurch, dass ein in Einbaulage unten liegender Abschnitt des Sandcontainers mit einer wassergesättigten Füllung und/oder durch Zugabe von im Vergleich zur restlichen Sandfüllung des Sandcontainers schwererem Material eine höhere Dichte hat, wird der unten liegende Abschnitt des Sandcontainers ballastiert, womit er eine stabilere Lage beim Absinken im Wasserkörper einnimmt und Dreh- sowie seitliche Bewegungen verhindert bzw. reduziert werden. Folglich kann ein Sandcontainer von einem Schiff durch freies Absinken lassen durch den Wasserkörper erheblich genauer am Meeresboden positioniert werden. Die Trajektorie des Sandcontainers durch den Wasserkörper ist durch die Ballastierung deutlich zielgerichteter und nicht durch zufällige Taumelbewegungen, Drehungen und seitliches Abgleiten bestimmt.The fact that a lying in installation position below section of the sand container with a water-saturated filling and / or by adding compared to the remaining sand filling of the sand container heavier material has a higher density, the lower portion of the sand container is ballasted, bringing a more stable position in the Sinking in the water body takes and rotation and lateral movements are prevented or reduced. Consequently, a sand container can be positioned by a ship by free sinking through the body of water much more accurately on the seabed. The trajectory of the sand container through the body of water is determined by the ballast clearly targeted and not by random tumbling movements, rotations and lateral sliding.
Verfahrensgemäß wird der Sandcontainer mit seinem in Einbaulage unten liegenden, ballastierten Abschnitt auf die Wasseroberfläche gesetzt, eingetaucht und in dieser Orientierung losgelassen, bei der Sinkbewegung hält der Container durch die Ballastierung seine relative Ausrichtung im Wasserkörper und sinkt entsprechend seines Relativgewichts im Wasser und seinem Strömungswiderstand im Wesentlichen gradlinig zum Meeresboden.According to the sand container is placed with its in installation position down, ballastierten section on the water surface, immersed and released in this orientation, in the sinking the container holds by the ballast its relative orientation in the water body and decreases according to its relative weight in the water and its flow resistance in Essentially straightforward to the seabed.
Die Umströmung des Sandcontainers beim Absinken kann dadurch optimiert werden, dass die geotextile Hülle in seinem in Einbaulage unten liegenden Abschnitt eine Spitze, konvexe Auswölbung oder dreiseitiges Prisma ausgebildet hat. Durch diese strömungstechnische Optimierung wird das Sinkverhalten weiter stabilisiert und die Sinkgeschwindigkeit erhöht.The flow around the sand container when sinking can be optimized by the fact that the geotextile shell has formed in its in-mounting position below section a tip, convex protrusion or three-sided prism. This flow optimization further stabilizes the sinking behavior and increases the sinking rate.
Alternativ kann auch die bekannte Kissenform des geotextilen Sandcontainers beibehalten werden, wobei die Einbaulage mit seinem größten Querschnitt flach auf dem Meeresboden aufliegend orientiert ist. Versuche haben gezeigt, dass bei einem kissenförmigen Sandcontainer ein Absinken mit seinem größten Querschnitt normal zur Absinkrichtung orientiert eine stabile Lage im Wasser darstellt, womit ein im Wesentlichen gradliniger Sinkvorgang erfolgt. Allerdings ist bei der bekannten Kissenform der Absinkvorgang relativ langsam, da der Strömungswiderstand um das Kissen relativ hoch ist. Entsprechend besteht bei größeren Wassertiefen und/oder stärkeren Meeresströmungen eine höhere Gefahr der Verdriftung.Alternatively, the known cushion shape of the geotextile sand container can be maintained, the installation position with its largest cross-section flat oriented on the seabed. Experiments have shown that in a pillow-shaped sand container a sinking with its largest cross-section oriented normal to Absinkrichtung represents a stable position in the water, which is a substantially straight-line sinking. However, in the known pillow shape, the sinking process is relatively slow, since the flow resistance around the pillow is relatively high. Accordingly, there is a higher risk of dripping with larger water depths and / or stronger ocean currents.
Ergänzend sind an den in Einbaulage orientierten Längsseiten des Sandcontainers hydrodynamische Leitflügel ausgebildet. Diese Leitflügel stabilisieren den Absinkvorgang des ballastierten Sandcontainers, insbesondere bei einer schnelleren Sinkgeschwindigkeit, die durch eine hydrodynamisch optimierte Formgebung des Sandcontainers, beispielsweise in Art eines Torpedo-Ankers ermöglicht wird. Bevorzugt sind die Leitflügel aus dem Geotextil der Hülle gebildet, da somit keine weiteren unterschiedlichen Materialien am Sandcontainer vorzusehen sind und Beschädigungen von nebeneinander liegenden und/oder aneinander vorbeibewegten Sandcontainern vermieden werden.In addition, hydrodynamic guide vanes are formed on the longitudinal sides of the sand container oriented in the installation position. This guide wings stabilize the sinking of the ballasted sand container, especially at a faster sinking speed, which is made possible by a hydrodynamically optimized shaping of the sand container, for example in the manner of a torpedo armature. Preferably, the guide vanes are formed from the geotextile of the shell, as there are thus no further different materials to be provided on the sand container and damage to adjacent and / or passing sand containers are avoided.
Wenn der Sandcontainer in Absinkrichtung langgestreckt ausgeführt ist, verringert sich, bevorzugt zusammen mit den Merkmalen von Unteranspruch 2, der Strömungswiderstand im Wasserkörper in Absinkrichtung erheblich, so dass die Absinkgeschwindigkeit steigt.If the sand container is designed to be elongated in the sinking direction, the flow resistance in the water body in the sinking direction decreases significantly, preferably together with the features of
Wenn sich der Sandcontainer zum in Absinkrichtung oberen Ende verjüngt, wird der Strömungswiderstand weiter verringert, so dass der Sandcontainer in Art eines Torpedo-Ankers mit relativ hoher Sinkgeschwindigkeit und damit in sehr gradliniger und von anderen Einflüssen, wie beispielsweise der Meeresströmung, kaum beeinflusster Art zum Meeresboden sinken wird.When the sand container tapers towards the upper end in Absinkrichtung, the flow resistance is further reduced, so that the sand container in the manner of a torpedo armature with a relatively high rate of descent and thus in a very straightforward and by other influences, such as the ocean currents, hardly affected kind to Seabed will sink.
Verfahrensgemäß ist es wichtig, dass der abzusenkende Sandcontainer spontan losgelassen wird, ohne dabei Bewegungsimpulse auf den Sandcontainer zu übertragen. Somit kann vermieden werden, dass der Sandcontainer im Moment des Loslassens im Wasserkörper noch eine Orientierungsveränderung erhält und somit sein eigentliches Ziel am Meeresboden nicht mit ausreichender Genauigkeit trifft.According to the method, it is important that the sand container to be lowered is released spontaneously without transmitting motion impulses to the sand container. Thus it can be avoided that the sand container at the moment of letting go in the body of water still receives a change in orientation and thus does not meet its actual destination on the seabed with sufficient accuracy.
Wenn Meeresströmungen im Wasserkörper im Zielbereich zum genauen Positionieren des Sandcontainers an der Wasseroberfläche gemessen und/oder abgeschätzt werden, kann das Ablageziel am Meeresboden für den Sandcontainer durch daraus errechnetes Vorhalten auch bei relativ langsam absinkenden Sandcontainern (Kissencontainern) oder bei sehr starken Meeresströmungen zielgenau erreicht werden.If ocean currents in the water body are measured and / or estimated in the target area for accurately positioning the sand container on the water surface, the storage target on the seabed for the sand container can be precisely reached by providing calculated hold even with relatively slowly sinking sand containers (pillow containers) or with very strong ocean currents ,

In einer nicht weiter dargestellten Ausführungsform verjüngt sich das obere Ende des Sandcontainers, so dass eine weitere Verringerung des hydraulischen Widerstands beim Absinken des Sandcontainers erreicht wird. Entsprechend erreicht der so ausgebildete Sandcontainer eine relativ hohe Absinkgeschwindigkeit, ähnlich wie bei Torpedo-Ankern bekannt.In a non-illustrated embodiment, the upper end of the sand container tapers, so that a further reduction of the hydraulic resistance is achieved in the sinking of the sand container. Accordingly, the sand container thus formed reaches a relatively high sinking speed, similar to torpedo anchors known.
Insgesamt wird herausgestellt, dass durch die Ballastierung des Sandcontainers in seinem in Einbaulage unten liegenden Abschnitt 11 und bedarfsweise durch hydrodynamisch geeignete Ausbildung der bei der Absinkbewegung angeströmten Fläche und der abgewandten Fläche sowie Ausbildung von Flügeln 15 entlang der Längsseiten des Sandcontainers eine erhebliche Stabilisierung der Bewegungsbahn des Sandcontainers im Absinkvorgang erreicht wird. Ferner wird eine Erhöhung der Absinkgeschwindigkeit erreicht, so dass etwaig im Wasserkörper wirkende laterale Strömungen nur geringen Einfluss auf die Zielgenauigkeit des abzusenkenden Sandcontainers haben. Ferner kann durch geeignete Messmittel die Meeresströmung gemessen und die Positionierung des Sandcontainers an der Wasseroberfläche so gewählt (vorgehalten) werden, dass der Sandcontainer trotz der Meeresströmung sein Ziel genau erreicht.Overall, it is found that by the ballasting of the sand container in its in-mounting position below
