Abstract: The present invention relates to a hose arrangement for creating a bubble curtain in bodies of water, comprising at least one air hose including an interior space enclosed by a wall, where a perforation consisting of individual punctures is introduced in the wall at least in an upper, first circumferential area, from which air can be discharged, when the interior space is pressurized, for creating a bubble curtain extending in the longitudinal direction of the air hose, and a ballast receptacle including a receiving area extending in the longitudinal direction, in which an elongated ballast element is received.

Abstract: The present invention relates to a hose arrangement (100) for creating a bubble curtain (BS) in bodies of water, comprising at least one air hose (4) including an interior space (4b) enclosed by a wall (4a), where a perforation (9) consisting of individual punctures (9a) is introduced in the wall (4a) at least in an upper, first circumferential area (B1), from which air can be discharged, when the interior space (4b) is pressurized, for creating a bubble curtain (BC) extending in the longitudinal direction (X) of the air hose (4), and a ballast receptacle (20) including a receiving area (8) extending in the longitudinal direction (X), in which an elongates ballast element (21) is received.

Abstract: The present disclosure relates to a container with an encasement, the encasement surrounding a filling, whereby the encasement is made of a yarn, the yarn comprising a core and a sheath surrounding this at least in part, where the core comprises a mineral fibre extending in the longitudinal direction of the yarn. According to the present disclosure, it is provided for the sheath to comprise at least one biodegradable sheath fibre, whereby the mineral fibre is encased, at least in certain regions, by the at least one biodegradable sheath fibre.
