Abstract: A system for draining sludge is provided using water-permeable hoses which are closed at both ends and filled with sludge. A first, lower row of sludge-filled hoses located parallel to one another, and one beside the other, has arranged on it at least a second row of sludge-filled hoses located parallel to one another, and one beside the other. The second row can have arranged on it a third, fourth or further row of sludge-filled hoses. On the upper side of each row which bears at least one further row of sludge-filled hoses, drainage pipes, which extend over the length of the hoses, are arranged in the upwardly open channels, which are formed by in each case two sludge-filled hoses located one beside the other. The hoses have a diameter of 0.4 to 1.6 m and a length of at least 10 m.

Abstract: Composite fabric for reinforcing soil layers, including a textile lattice and a water-permeable, flat textile structure which is joined to the lattice. The invention provides a geotextile composite fabric web whose positioning not only achieves good reinforcement but also allows for the rapid and reliable consolidation of the subsoil situated beneath the textile composite fabric web. The lattice includes strips which are at least 4 cm wide, extend at distances of at least 30 cm in the longitudinal direction of the composite fabric web and have high tensile strength, and second strips which are at least 4 cm wide, extend at distances of at least 30 cm at right angles to the first strips and have high tensile strength. At the points of intersection, the second strips are joined to the first strips in a non-slip manner.
