Definitions

  • the present invention relates to a hose arrangement for generating a bubble curtain in waters according to the preamble of claim 1.
  • Such a hose arrangement is used in particular for sound insulation when driving a pile into the bottom of a body of water.
  • a so-called large bubble curtain is created.
  • an air hose is laid around the construction site and is attached to the bottom of the body of water.
  • the air hose is supplied with compressed air via at least one compressor, the air hose having a large number of holes or punctures along its length.
  • the compressed air exits through the punctures, forming a curtain of bubbles rising from the air hose.
  • This bubble curtain of air bubbles forms a physical and acoustically insulating barrier for the sound waves that arise during pile driving.
  • the bubble curtains are intended to protect hearing-sensitive marine mammals such as porpoises and seals from hearing damage.
  • the air hoses While at the beginning of the development of the large bubble curtain system, the air hoses were still attached to the bottom of the water by divers and after the ramming work was completed they were either left as lost on the bottom of the water or removed again by divers the air hoses are now positioned using a laying vessel. On these ships, the air hose is rolled up or reeled onto a winch, from which the air hose is reeled off over the stern of the ship and placed on the bottom of the water in a ring around the construction site.
  • metal sleeves are attached to the air hose at intervals along the entire length of the air hose and are connected to one another with a chain.
  • the cuffs and the chain serve as ballast so that the air hose, which is filled with air during operation, remains on the bottom of the water or is secured to the bottom of the water, and on the other hand, they can act as a tension member to absorb the tensile forces that occur when laying and recovering the lines.
  • an air hose is used that is made of a rubber or a polymer.
  • the air hose is provided with a fabric layer or wire mesh insert.
  • the wall of the air hose has a large number of bores or holes. These have a diameter of about 0.5 to about 5 mm and a distance of about 100 cm to about 10 cm from each other.
  • a weighting element in the form of a chain is inserted into the air hose.
  • the chain arranged inside the air hose does not affect the windability of the air hose, so that large lengths of the air hose can be placed on a winding device.
  • the chain arranged in the air hose hinders the air flow within the air hose and promotes the penetration of water through the holes in the wall when the compressed air is switched off.
  • the air hose is usually made of rubber or other polymer materials and the wall is reinforced by at least one additional layer of fabric in order to make the air hose more pressure-stable and, above all, to ensure sufficient tensile strength to prevent damage to the air hose to avoid the tensile forces that occur during operation.
  • An air hose designed in this way must then be processed mechanically or chemically or thermally in order to be able to connect it to the ballast hose, which requires an additional processing step that could possibly damage the air hose or at least impair the discharge of the air bubbles.
  • the DE 20 2014 005 397 U1 describes another possibility Formation of a bubble curtain for sound insulation on a pile to be driven into the seabed.
  • the pile is surrounded by a structure, with a bubble curtain being provided in the space between the structure and the pile.
  • the structure consists of a package of rings connected to each other by a textile fabric.
  • the rings and the textile fabric form a tube that surrounds the post.
  • This air tube forms a kind of cage that reduces the flow of seawater in the space between the tube and the pole.
  • DE 10 2017 104457 A1 a hose arrangement corresponding to the preamble of claim 1.
  • the object of the present invention is to provide a generic hose arrangement which eliminates the disadvantages of the prior art, in particular fixes the air hose to the ballast element in a simple manner and, if necessary, protects it well against external forces and at the same time provides a uniform bubble curtain enabled.
  • a hose arrangement for generating a bubble curtain in water, in which the air hose is preferably covered over its entire longitudinal extent or length or at least over 75% of its length by a holding casing with material webs and openings in between, the air hose being covered over the holding casing, and preferably exclusively via this, is connected to the ballast receptacle in a connection area and the openings are positioned at least in the first peripheral area of the air hose to enable air to escape from the perforation in the air hose.
  • an additional mesh-like sheathing or sheathing provided with openings is provided as a “connecting element” between the air hose and the ballast holder. Thanks to its openings, this does not impair the air being bubbled out of the air hose and at the same time can hold the air hose securely by encasing it and therefore preventing the air hose from buoyancy under pressure.
  • the holding casing can then be connected to the ballast holder under lower requirements and, according to one embodiment, can even partially form it without the air hose itself being influenced, since the mechanical and / or thermal and / or chemical effects that are necessary to form the connection are not related to the air hose itself, since the holding casing is preferably not part of the air hose itself.
  • the holding casing is formed by a network with interconnected fibers, in particular textile or mineral fibers, which form the material webs, and mesh-like openings between them.
  • the net is fixed with lower ends in the connection area to the ballast receptacle, in particular is clamped therewith. This allows a simple connection to be made to the ballast holder, which simplifies the assembly process.
  • the holding casing is formed by a first portion of a polymer band, preferably made of a fabric layer-reinforced polymer, which is folded back on itself and thereby encases the air hose, the polymer band being left out, in particular cut out, in the first portion or is punched out so that openings are formed between material webs which, in the folded-back state of the first partial region, are positioned at least in the first peripheral region of the air hose to enable air to escape from the perforation in the air hose.
  • This makes it possible to provide an alternative option for the holding casing, in which the openings and material webs can be specifically adapted to the application and also the dimensions of the air hose and the weighting element.
  • the material webs can also be subsequently attached to the polymer band in the first partial area, for example by riveting or gluing.
  • the first portion of the polymer tape is then designed in two parts.
  • the first partial region of the polymer tape essentially covers the entire surface of a second peripheral region of the air hose, the second peripheral region preferably being unperforated.
  • peripheral areas of the air hose that do not necessarily have to be exposed can remain covered, so that they are protected from damage, particularly during transport or installation of the hose arrangement on the seabed.
  • the ballast receptacle is formed by a second portion of the polymer tape, which is on is folded back to form the receiving area and to accommodate the weighting element, the first portion and the second portion being made in one piece.
  • a one-piece design of the ballast holder (second sub-area) and the holding casing (first sub-area) can be provided, with the sub-areas forming spaces or receiving areas for the air hose or the weighting element by correspondingly folding back or folding over one another and with the aid of a subsequent connection process .
  • This makes it possible to provide a one-piece solution that can be precisely pre-assembled and can only be assembled at the place of use by turning it over, which simplifies both transport and assembly (and also disassembly).
  • the ballast receptacle is formed by a deformable, plate-shaped element (comparable to the second portion of the polymer tape), which is folded back on itself in a loop-like manner with its edge regions in such a way that a tubular shape with a lengthwise expanded Receiving area results in which the weighting element is received, the edge areas of the plate-shaped element being connected to the holding casing in the connection area.
  • a two-part solution is also conceivable, which can then be combined with a net or a polymer tape (see first part) as a holding casing in order to form the hose arrangement.
  • connecting means are arranged between the holding casing and the ballast receptacle, the connecting means in particular being a screw connection and/or a rope-shaped or a band-shaped connecting means and/or nails and/or rivets and/or pilot bolts are carried out.
  • the connecting means in particular being a screw connection and/or a rope-shaped or a band-shaped connecting means and/or nails and/or rivets and/or pilot bolts are carried out.
  • the holding casing rests loosely over the entire surface of the air hose or that the holding casing is only partially connected to the air hose, for example at the end and/or at intermediate positions, in particular via a cohesive connection, e.g. a PU adhesive, or by a form-fitting and /or non-positive connection, for example a clamp or a rivet connection.
  • a cohesive connection e.g. a PU adhesive
  • a form-fitting and /or non-positive connection for example a clamp or a rivet connection.
  • the hose arrangement has a plurality of air hoses, with two air hoses adjacent in the longitudinal direction being sealingly connected to one another via a hose coupling. This allows a variable structure of the hose arrangement to be achieved, whereby the holding casing can also be continued via the hose coupling, depending on the design.
  • a hose arrangement 100 which has an air hose 4 that can be supplied with compressed air, is placed on the seabed 3 in a ring around the pile 1 to be driven in.
  • a supply ship 5 travels approximately in a circle around the pole 1, with the hose arrangement 100 with the air hose 4 coming from a winding drum 6 located on board the supply ship 5 is drummed off.
  • On board the supply ship 5 there is also at least one special compressor 7, with the help of which compressed air is pressed into the air hose 4 of the hose arrangement 100.
  • the compressed air can be pressed in from one end of the air hose 4 or from both ends of the air hose 4.

  • an air hose 4 is of length L (see Fig. Fig. 5 ), which can be between 20m and 30m, for example, with a wall 4a made of fabric layer-reinforced rubber or a comparable polymer material, which is surrounded or encased by a holding casing 10.
  • the holding casing 10 generally consists of material webs 10a, between which openings 10b are formed, so that parts of the air hose 4 are exposed in order to allow air bubbles to escape from the air hose 4.
  • a network 12 is provided, the textile and / or mineral fibers of which form the material webs 10a, which are linked to one another at crossing points 10c, so that regular openings 10b (meshes) are formed between the material webs 10a.
  • the holding casing 10 is formed by a first portion 13a of a fabric layer-reinforced polymer tape 13 made of a rubber or a comparable polymer material.
  • the material webs 10a and the openings 10b are created by punching out the polymer band 13 in areas. Examples are in Fig. 6 or Fig.
  • the material webs 10a can also be manufactured separately in this embodiment, These preferably have the same or a comparable elastic material as the polymer band 13 and are attached with their ends to the polymer band, for example by riveting or gluing, so that the openings 10b are formed between them.
  • the polymer band 13 is then manufactured in several parts in this first partial area 13a.
  • the hose arrangement 100 in both exemplary embodiments has a ballast holder 20 for a weighting element 21, which is also extended in the longitudinal direction X, by means of which the hose arrangement 100 can be held on the seabed 3.
  • a connection between the air hose 4 and the ballast receptacle 20 is preferably only achieved via the holding casing 10, so that the air hose 4 itself does not have to be subjected to any additional large-area thermal and/or chemical and/or mechanical treatment.
  • An additional adhesive connection for example via a PU adhesive, can be provided at certain points, for example at the end and at selected intermediate positions, between the holding casing 10 and the air hose 4, in order to avoid slipping or twisting of the air hose 4 within the holding casing 10.
  • a non-positive and/or positive connection can also be provided at certain points between the holding casing 10 and the air hose 4, for example by a clamp connection or a rivet connection, for example via a blind rivet piercing the holding casing 10 and the air hose 4.
  • Figure 3 is the hose arrangement 100 with the network 12 as a holding casing 10 shown with dashed lines in a state in which the air hose 4 is not pressurized with compressed air, whereby the air hose 4 is compressed flat in particular by the water pressure acting from the environment U, the network 12 of this movement can follow (not shown for clarity).
  • an interior space 4b of the air hose 4 is pressurized with compressed air, whereupon the air hose 4 expands and assumes a round shape or an oval shape.
  • the air hose 4 of the hose arrangement 100 with the polymer band 13 as a holding casing 10 behaves accordingly in the unpressurized or pressurized state.
  • the wall 4a of the air hose 4 is in accordance with this Fig. 2 or 5
  • a perforation 9 is introduced on the top side along the ridge line, for example by punching.
  • This perforation 9 is preferably formed from the finest slot-shaped or point-like punctures 9a, which are designed in such a way that they can open automatically over a certain opening width of between 1 mm and 3 mm under certain pressure conditions acting in the interior 4b. They act as valves, so to speak, so that the pressurized air can escape from the interior 4b in fine bubbles via the several punctures 9a into the environment U in order to form a bubble curtain BC, which in Fig. 5 is only indicated schematically.
  • the punctures 9a or the perforation 9 are or are in a first peripheral region B1 arranged on the top (see Fig. Fig. 4 ) is introduced into the wall 4a in the area of the ridge line, while the wall 4a remains unperforated in a second peripheral area B2.

  • one to twenty finest punctures 9a per cm 2 are formed in the wall 4a of the air hose 4 in order to form a bubble curtain BC that bubbles out evenly in the longitudinal direction X.
  • the opening width or the size of the individual punctures 9a can also vary in the longitudinal direction
  • the air hose 4 can therefore also be composed of partial areas with different puncture sizes or opening widths.
  • the perforation 9 is then designed in such a way that even with different water pressures in the area U, which arise due to differences in level of the seabed 3, the compressed air can bubble out in fine bubbles evenly distributed over the air hose 4 (in the longitudinal direction X).
  • the respective holding casing 10 surrounds the air hose 4 both in the first circumferential region B1 and in the second circumferential region B2, with the above-described escape of the air bubbles in the first circumferential region B1 not being significantly affected due to the openings 10b (punched outs or meshes) in the retaining casing 10.
  • the openings 10b are preferably positioned in the holding casing 10 in such a way that the air hose 4 is exposed over a large area at least in the first peripheral region B1 and the material webs 10a only cover smaller areas of the air hose 4 or the perforation 9, so that a bubble curtain BC is not formed is noticeably impaired.

  • the two lower ends 14a, 14b of the net 12 designed as a holding casing 10 converge in a lower apex region S of the wall 4a and are releasably connected to the ballast receptacle 20 in a connection region 15 over the entire longitudinal extent.
  • the ballast holder 20 is formed in this embodiment by an elastically deformable, plate-shaped element 20a (or band-shaped comparable to the polymer band 13) made of a rubber material or a comparable polymer material, the plate-shaped element 20a with its edge regions 20b loop-like around the longitudinal axis is folded back on itself or bent over, so that a tubular shape running in the longitudinal direction X with a receiving area 8 results.
  • the edge regions 20b of the folded back plate-shaped element 20a close the lower ends 14a, 14b of the net 12 in the connection region 15 essentially over the entire length L of the air hose 4 between them.
  • a connecting means 16 is provided, which in the present case is formed by a screw connection 16a, the screws being inserted through connecting holes 18 in the edge regions 20b as well as through the openings 10b or meshes of the net 12.
  • the lower ends 14a, 14b of the net 12 are clamped between the edge regions 20b and, due to the mesh-like structure of the net 12, the net 12 is also prevented from being pulled off from the edge regions 20b.
