Abstract

The invention discloses a method for building an underwater construction comprising a hardened grout, wherein the device has a housing with a receiving volume, and moreover a filter apparatus which is arranged at least partially therein and which is designed to filter out constituents which have been released from the grout. A filter apparatus which can be used in the device, and a method for filling a device for building an underwater construction with a grout, using this filter apparatus, are moreover.

First claim

What is claimed is:

1. A device for building an underwater construction with a grout, the device comprising:
a housing which has a receiving volume for receiving the grout, the housing having
a filling opening for pouring the grout into the receiving volume;
an outlet opening for an outlet of water forced out of the receiving volume; and
an outer tube and an inner tube;

wherein
a clear width of the outer tube is greater than an outer diameter of the inner tube; and
the inner tube is inserted into the outer tube such that the outer tube surrounds the inner tube and the receiving volume of the housing is formed by an intermediate space between the outer tube and the inner tube;

wherein
the device has at least one filter apparatus;
the filter apparatus is designed to filter out constituents which are released from the grout by water situated in the receiving volume; and
the filter apparatus is arranged at least partially in the receiving volume.

2. The device as claimed in claim 1 , wherein the filter apparatus is arranged between the filling opening and the outlet opening of the housing.

3. The device as claimed in claim 1 , wherein the filter apparatus is arranged to have a changeable position in the receiving volume of the housing.

4. The device as claimed in claim 1 , wherein the filter apparatus is arranged in an immediate vicinity of the outlet opening arranged above the filling opening in an installed position of the housing.

5. The device as claimed in claim 1 , wherein the filter apparatus is weighed down by a sinker.

6. The device as claimed in claim 1 , wherein the filter apparatus comprises at least one water-permeable filter sleeve filled with a filter medium.

7. A method for filling a device for building an underwater construction with a grout, the method comprising:
attaining the device for building the underwater construction with the grout, the device comprising a housing which has a receiving volume for receiving the grout, the housing having
a filling opening for pouring the grout into the receiving volume;
an outlet opening for an outlet of water forced out of the receiving volume; and
an outer tube and an inner tube;

wherein
a clear width of the outer tube is greater than an outer diameter of the inner tube; and
the inner tube is inserted into the outer tube such that the outer tube surrounds the inner tube and the receiving volume of the housing is formed by an intermediate space between the outer tube and the inner tube;

wherein
the device has at least one filter apparatus;
the filter apparatus is designed to filter out constituents which are released from the grout by water situated in the receiving volume;
the filter apparatus is arranged at least partially in the receiving volume;

positioning the housing of the device in or on an underwater subsoil; and
pouring the grout into the receiving volume of the housing, wherein the filter apparatus has been introduced before the grout is poured into the receiving volume of the housing.

8. The method as claimed in claim 7 , further comprising recovering the filter apparatus when pushed out of the receiving volume by the grout.
