Description

The invention relates to a method for eliminating Material, especially deposits or deposits and / or loading grew, below the level of a preferably liquid Me diums, preferably a method for cleaning in the me surfaces, for example of walls, bodies or similar.

The invention further relates to a device for beating of material, especially deposits or deposits and / or vegetation, preferably below the level liquid medium, preferably for performing the aforementioned procedure.

There is a wide range of work in which material under the Mirror of a medium must be eliminated, especially under half a water surface in the water.

For example, on surfaces of pools, floats pern, tanks, containers, pipes or the like the deposits or deposits are removed once before Repair or maintenance work can be carried out. Such work often has to be below the water surface area, i.e. while these areas are in the Water.  

In addition, basins, rivers, ports, canals, Kü dash lines or the like, as well as tanks or containers container to be cleaned from time to time so the function ability remains intact.

It may also be necessary to carry out work in which for example in the bottom of a body of water or more generally one Medium-containing basin wells are introduced to lay pipelines or other bodies organize.

All of this work must be carried out as carefully as possible can be tet. In particular, with regard to even Pollutants that are released are becoming increasingly common Requirement that the material removed in such work trolled and completely disposed of.

The invention has for its object a method or a device for removing material for implementation tion or for use below the level of a medium admit at which the material to be removed con trolled aside.

With regard to the procedure, the task set solved according to the invention in that the material with little Irradiated at least one jet and sucked in at the same time or suctioned off.

The method according to the invention is therefore advantageous the material to be removed is not just simply one cleaning surface, after which the dissolved material through existing flows are transported away or distributed  could, but the loosened material is at the same time when loosening sucked in so that a controlled elimination of the mate rials takes place without material diffusing in an uncontrolled manner could.

The medium is preferably used to generate the jet se itself used, for example, by a pump circuit will be produced. This is possible in a particularly simple manner Lich if the medium is water.

When sucking or sucking off the dissolved material preferably sucked a medium-material mixture. A next ste further development of the method provides that the material is separated from the medium after suction. This is at for example possible with a filter or sieve device. After the separation, the medium separated from the material preferably fed to the jet (again).

This is a controlled elimination, especially Ent supply, the material possible, and in a very economical way way in which the medium in which the work is carried out be carried out, even multiple times as a vehicle for the material and as a nozzle jet medium to dissolve the mate rials is used.

After a further development of the invention The method can also, preferably metered, the jet at least one additional additive of any phase is added will. This can be gaseous, liquid or act solid substances, in particular the dissolving process of start removing material from a surface to be cleaned  can increase. For example, can also be separated, previously side material as additive to the jet stream (dosed) be added again. For example, this makes sense if there is an area of sludge in a body of water should be freed. The sludge already sucked out, which in the we contains considerable sands, the jet can partially again are fed so that a harder, better solvent nozzles beam arises, for which the main thing is preferably the um ambient water, for example sea water.
