Definitions

  • the present invention relates to a method and a plant for the construction of concrete structures in seawater, preferably in greater coastal distance.
  • foundations floating foundations which include a plurality of anchoring elements positioned on the seabed as ballast body and hold the wind turbine at the specified location.
  • the anchoring elements resting on the seabed for positioning are made of concrete with a volume of up to 1,000 m 3 each or more.
  • the use of land-based or anchoring structures on land is associated with high costs and high costs in terms of transport.
  • work vessels are used for the construction of concrete structures at sea, which have a mixing and delivery unit to mix an underwater concrete as a standard concrete at the site and pump to the seabed. All required for the concrete recipe raw materials (cement, sand, gravel, water, additives) are from their Heinrichs. The place of extraction was taken to a port, loaded there in silos on the working ship and taken from there to the place of work. Because of the limited loading capacity of the working ships, they must return to the port more frequently than would be required, for example, to replace the personnel.
  • Another object of the present invention is to provide such a method and apparatus for use at a greater distance from the shore, which requires the least possible frequency of ship movements.
  • the method according to the invention can be in contact with seawater, in particular standing in sea concrete structures even at a greater distance from the coast, for example, a ship-borne concrete mixing and conveyor system, ie ultimately with a special ship.
  • the total weight of the structures erected by the ship in one action may be substantially greater than the carrying capacity of the ship.
  • the total weight of the concrete structures can be significantly greater than the weight of land-borne material.
  • the invention makes it possible by exclusively or at least predominantly aggregates and mixing water are used for the production of the concrete from which the structure is built, which are taken from the sea.
  • the aggregate is sea gravel from the seabed.
  • the mixing water is seawater.
  • the terms "seawater” and “seawater” are used synonymously for saline water, which is not freshwater.
  • the ship carries at least one ash-generated binder component in suitable bunkers.
  • the remaining constituents of the concrete in particular its aggregate and its mixing water, originate from the sea and are correspondingly saline. It has been found that with saline giants, which have been obtained in the sea and according to saline mixing water can produce a durable and durable concrete. This is particularly the case when the aggregate extracted comes from a deposit from whose vicinity suitable seawater has been taken, which has the same salt content as the seawater with which the aggregate was previously in long-term contact.
  • cement and fly ash are suitable as the binder component.
  • a binder of cement, fly ash and additives can be used here.
  • a large part for example about 50% of the total transport capacity of the production ship in question can be used to transport the binder component and optionally the metal structures or scaffolds to be installed in the concrete structure. This results in long cycles for the use of the production ship. The number of harbor voyages depends on the loading capacity of the binder.
  • the production ship preferably contains at least in a preferred embodiment a plurality of silo containers, in which seaweed obtained from the seabed can be temporarily stored.
  • the intermediate storage can serve several purposes. For example, it may allow drainage of the sea gravel to adjust a desired degree of moisture.
  • Such silo containers can be regularly refilled with sea gravel, which is obtained, for example, by a suction dredger in the rinsing process, transported to the production vessel and then conveyed into the aggregate bunker. This method is particularly suitable for production in larger coastal distance, which also results in cost savings, because the port only for the binder uptake, i. less often must be approached.
  • the production vessel can also load its bunkers with sands and gullies from silo facilities in the port to begin production before the suction dredger delivers sand and gravel from the seabed.
  • the production ship preferably has a concrete conveyor system in addition to the mixing device.
  • the concrete delivery system consists of storage tanks as an intermediate station from the transition of the discontinuous production of fresh concrete and the continuous pumping by stationary concrete pumps in the required number (usually two or three) and designed according to the building specific installation conditions piping including the interposed depending on the requirement boom.
  • the concrete installation on the seabed is carried out in the process of underwater concrete. It can be installed while monitoring and monitoring equipment for concrete installation.
  • the aggregate supply with the suction dredger can start at regular intervals in order to fill the designated bunker with sea gravel and to start to drain it.
  • the first ready fresh concrete is then with the Concrete delivery system filled in the sunken on the seabed metal frame, which also serves as formwork.
  • the seabed metal frame which also serves as formwork.
  • it is externally provided with a preferably water-permeable wall, for example a reinforced textile fleece.
  • the individual anchoring elements are now erected in the same way, with the unclassified aggregate, ie the sea gravel taken from the seabed and brought in via the suction dredger, being used as soon as necessary for further concrete production.
  • the mixing water is always seawater.
  • the concrete production and concreting work can be carried out continuously and quickly without major interruptions to the supply of aggregate and fresh water. The construction times are significantly reduced.
  • the inventive method is also suitable for the construction of concrete structures near the sea on land, the corresponding mixing plant and required for material storage bunkers can be land-based.
  • unclassified sea gravel from a submarine deposit in combination with sea water is also used as mixing water in this case, so that natural resources or expensive replacement materials and energy can also be saved here.

  • FIG. 2 shows the material flow in the process carried out on the production vessel
  • FIG. 3 shows the production vessel when erecting a ballast body
  • Figure 4 shows the suction dredger in the removal of sea gravel
  • Figure 5 shows the production ship in a schematic representation.
  • a suction dredger 9 is placed, which serves for the extraction of sea gravel from a mining site on the seabed. It has for this purpose a corresponding technical equipment 11, as it is symbolically illustrated in Figure 4.
  • the suction dredger 9 may periodically start the production ship 8 to transfer the recovered sea gravel 14 as an aggregate for concrete production.
  • the production ship 8 is illustrated separately in FIGS. 3 and 5. These representations are schematized. The production ship 8 is symbolized in Figure 5 only on the basis of the rough outline of his hull with the omission of all other construction and installations.
  • the production ship 8 includes a plant 15 for the production of fresh concrete from a brought by land binder component and additives and sea water and sea gravel.
  • the system 15 has one or more storage containers 16 for the binder component, for example cement, fly ash and additives.
  • the cement and the Fly ash can be stored in various storage containers or as a ready-made binder component in a reservoir.
  • the production vessel 8 has a mixing plant 17 suitable for concrete production. Preferably, in particular their coming into contact with the fresh concrete components made of seawater resistant material. This also applies to all subsequent to the mixing plant 17 components, for example, to the concrete conveyor 18 and one of the mixing plant 17 to the concrete conveyor 18 leading line and a leading away from the concrete conveyor 18 line leading to an apparent from Figure 3 concrete conveyor line 21 leads.
  • the production ship 8 preferably carries a plurality of bunkers 22 for storage with unclassified sea gravel. These bunkers 22 also serve to drain the sea gravel, i. its separation from the rinse water, which was brought to the suction dredger 9. For this purpose, the bunker 22 initially serve as settling vessels, being provided with outlets for the excess water. In addition, precipitating seawater can be supplied as mixing water to the mixer. Alternatively, seawater can be taken directly from the environment of the production ship 8 and preferably fed to the mixing plant 17 without separate treatment.
  • the bunkers 22 are filled at port stays with interim, unclassified sea gravel. About a conveyor and metering the bunker 22 are connected to the mixing plant 17.

  • the aggregate silo plant can be filled with unclassified marine gravel extracted from the sea.
  • the ship then runs out. In the scheme of Figure 1, it starts directly to the production site.
  • the production then begins immediately, as indicated in Figure 3, first with a loading crane one or more metal scaffolds 29 are lowered to the seabed.
  • the metal scaffolds wrap the concrete body to be produced and stiffen it, allowing excess water to drain off.
