Definitions

  • the invention relates to a method for increasing the water depth of a body of water, e.g. a fairway, a river, a port or the like, in particular for removing sludge deposits from the bottom of the body of water.
  • the invention further relates to a device for increasing the water depth of a body of water, in particular for removing sludge deposits from the bottom of the body of water, preferably a movable device, preferably an dredger, preferably for carrying out the aforementioned method.
  • the invention also relates to a flushing pipe of a flushing device, preferably for the aforementioned device.
  • the invention is therefore based on the object of specifying a method by means of which the water depth of a body of water can be increased and, after its implementation, a bottom of the body of water that is as flat as possible is left behind.
  • This object is achieved in that dredged material is dredged from the bottom of the body of water and that afterwards the bottom, which has become uneven due to the dredging, is leveled and preferably further lowered, that material of the bottom is whirled up by blasting with a medium and partly by existing natural and / or artificially generated flow is transported away, sometimes evenly distributed again.
  • excavation is advantageously carried out first, whereby an uneven ground can easily arise.
  • the material of the base is then whirled up so that it settles again at least more evenly, so that the unevenness caused by the excavation is compensated for.
  • the material swirled up in the bottom can also be transported over longer distances from the water in the water, so that the water depth can also be advantageously increased further by the swirling process.
  • a sufficient flow for the removal of the whirled up material can preferably also be generated artificially.
  • excavation is preferably carried out with a suction proboscis.
  • the proboscis is preferably pulled over the bottom of the body of water, with suction channels that look like furrows appear in the bottom of the body of water. These channels are leveled by the subsequent whirling process or the bottom is preferably lowered even further.
  • a flow can be used to remove the whirled up base material, which flow can be artificial or natural.
  • the existing flow is directed to a specific base area in a targeted and as concentrated manner as possible, so that the flow in this particular base area can propel the whirled up base material with a particularly great force.
  • An artificial flow can be generated in a particularly favorable manner by taking advantage of the propulsion of a device for carrying out the method, for example by moving a guide device with the device relative to which the water of the water flows, even when the water is at the bottom is more or less calm.
  • a device according to the invention for increasing the water depth of a body of water is characterized by an excavator device and by a flushing device with a flushing line for a flushing medium, at least a portion of which can be brought out to just above the bottom of the water, this part via at least one nozzle for generation a flushing medium jet.
  • a rinsing device is therefore provided, with which at least one jet of rinsing medium is generated, and just above the bottom of the water.
  • the base material is whirled up by means of this jet and is preferably distributed by the existing flow.
  • the existing excavator device preferably has an extractable proboscis.
  • the device according to the invention is preferably an excavator ship, in which the excavator device is arranged on the bow side than the flushing device, so that when the ship is propelled forward, the flushing device follows the dredging device with respect to the same area of the bottom of the body of water, i.e. an excavation process can first be carried out in the sense of the previously described method and the excavated ground is then leveled or further reduced by the flushing process.
  • the section of the flushing line that can be deployed above the bottom is arranged in the working position, preferably approximately dwars to the ship, that is to say transversely to the longitudinal axis of the ship, and approximately parallel to the base plane.
  • This part of a flushing line therefore, covering a certain working width, can also be pulled from the ground by a ship, as was conventionally the case with a rake, but the flushing line does not have to lie on the bottom, and therefore not as easily can get stuck on obstacles like such a rake.
  • the subsection of the flushing line to be routed above the ground is preferably a flushing pipe, on which are arranged at (regular) intervals approximately radially directed (obliquely) basic nozzles with which the flushing medium jet
  • a preferred embodiment of the flushing line provides that the flushing line is designed as an approximately U-shaped bracket, the base section of which is the subsection of the flushing line that can be brought out above the ground, this section running through under the keel or bottom of the ship in the working position and the free ends the leg portions of the bracket are articulated approximately in the area of the ship's side walls.
  • a further development of the invention for which independent protection is also claimed, provides a water guide surface that can be lowered above the ground.
  • an existing or generated flow can be directed to certain basic areas of the water, whereby the guiding process, for example taking into account the Bernoulli or the continuity equation, allows the flow in this basic area to be specifically increased or tightened.
  • the flow is preferably fed to the base region in that the flushing line with its nozzles whirls up the base in order to remove the material whirled up.
  • the guide surface is therefore preferably arranged directly upstream of the subsection of the flushing line which is led above the ground.
  • the directed flow also advantageously forms a water cushion, which additionally effectively prevents the subsequent subsection of the flushing line from sitting on the ground.
  • the guide surface has an angle of inclination of preferably approximately 45 ° obliquely to the base, in such a way that a wedge shape is formed between the guide surface and the base, the edge of the guide surface facing the expected flow with the greater distance from the base.
  • the efficiency of the flushing device is significantly increased by the relatively simple attachment of a guide surface.
  • the lower edge of the inclined guide surface facing away from the flow is preferably guided just above the base, so that the water flowing into the wedge shape between the base and the guide surface has to flow through a narrow gap between the lower edge of the guide surface and the base, whereby the base material is so strong entrains that the bottom behind the guide surface is hollowed down, that is, a step is created behind the area of the guide surface because the bottom in the area behind the guide surface is lowered by the flowing water.
  • the flushing pipe according to the invention of a flushing device preferably a device according to one or more of claims 4 to 11, in particular a device according to claims 9 and 10 or 11, is characterized by at least one approximately radially directed nozzle for generating a flushing medium jet and by an outside on Flush pipe arranged guide surface with an angle of attack in the angular range between radial and tangential.
  • the guide surface is preferably arranged directly on the flushing tube, in such an angular range that the guide surface is directed obliquely to the bottom in the working position of the flushing tube in the direction of the flushing tube.
  • the water flowing to the guide surface is thus forced through the guide surface under the flushing pipe, so that the base area under the flushing pipe is cleared away and, moreover, the flushing pipe rests more or less more securely against damage on a water cushion or water flow.
  • the guide surface preferably has an angle of attack of approximately 45 ° to the radial direction of the tube.
  • the guide surface is preferably attached to one of its longitudinal edges (directly) on the outer circumference of the flushing pipe.
  • the guide surface can be essentially a sheet metal that is welded to the tube.
  • the guide surface is preferably arranged a quarter of the circumference of the flushing pipe away from the nozzle or nozzles, preferably somewhat less. In the working position of the flushing pipe, the nozzles point essentially downwards in the direction of the base, preferably at a slight angle, while the guide surface is arranged on the front of the flushing pipe, the front being the side facing the expected flow or the Direction of travel of the ship pulling the flushing device.
  • the guide surface extends essentially along the flushing pipe.
  • the guide surface has a kink edge running parallel to the flushing pipe, along which the guide surface is bent in the direction away from the flushing pipe.
  • the guide surface is preferably designed such that the fixed section of the guide surface is so long that the free, kinked section of the guide surface is approximately congruent with the tangent running parallel to the radial. So while in the working position of the flushing pipe the fixed section of the guide surface attached to the flushing pipe is directed obliquely to the bottom, the free, kinked section runs approximately parallel to the bottom, so that overall the flowing water can flow into a type of funnel formed by the guide surface and into Direction is directed to the bottom to rinse the bottom.
  • console-like stiffening ribs are provided perpendicular to the guide surface and dividing the area under the guide surface into compartments. These ribs not only stiffen the guide surface, but also form compartments that could be viewed as flow channels for the water.
  • the guide surface is preferably designed as a guide plate.
  • Fig. 1 shows a dredger in side view.
  • This dredger has, in particular in connection with an excavator device, an extractable proboscis 1 which can be brought out and swung down in such a way that its free end can be pulled over the bottom 2 of a body of water, with channels 3 being dredged in the bottom 2 to increase the water depth.
  • This excavator device with suction nozzle 1 is arranged in the region of the bow of the dredger.
  • the dredger In the stern area, the dredger has a flushing device 4 with a flushing line 5.
  • a section of the flushing line 5 is a flushing pipe 6 which runs dwars, that is to say transversely to the longitudinal direction of the ship. In the working position drawn with solid lines in FIG. 1, this flushing pipe 6 is held just above the bottom 2 and runs under the stern area of the ship.
  • the flushing line 5 can be brought into a rest position, which is indicated in FIG. 1 with dash-dotted lines, in which the flushing line is above the water surface and parallel to the water surface, the flushing pipe 6 running behind the stern of the ship.
  • the flushing line 5 is pivotally arranged with its free ends in the area of the ship's side wall.
  • FIG. 2 which shows a top view of the dredger according to FIG. 1, it can be seen in particular that the flushing line 5 is essentially U-shaped, the flushing tube 6 being the basis of this U-shape.
  • Fig. 3 shows the stern area of the dredger according to Fig. 1 in side view again in an enlarged view.
  • the suction line 5 is shown again in more detail, also in its movement sequence when swiveling up and down.
  • the flushing line has in its two leg regions essentially two joints 7 and 8, around which it can be pivoted or angled.
  • the flushing tube 6 can be pivoted about the joint 8 and additionally about a joint 9, so that the flushing tube 6 does not get into the area of the propeller 10 of the dredger when the flushing line 5 is swung up into the rest position.
  • a nozzle 11 pointing downward in the working position is indicated, with which a flushing medium jet can be generated.
  • This nozzle is directed somewhat obliquely against the base 2.
  • a guide surface 12 is arranged along the flushing pipe 6, which is in the working position 6 just above the base 2 at approximately a 45 ° angle to the base 2, the free area 13 of the guide surface 12 is angled relative to the remaining area of the guide surface 12, in such a way that this free area 13 points approximately tangentially to the flushing pipe 6 and parallel to the base 2.
  • the guide surface 12 also has console-like stiffening ribs 14 which divide the area delimited from the regions of the guide surface 12, 13 into compartments or channels through which flowing water is passed, the flowing water being able to come from a natural flow of the water or else can be generated simply by the propulsion of the dredger.
  • nozzles 11 which are preferably arranged at regular intervals along the flushing pipe 6, for example approximately at the intervals at which the stiffening ribs 14 are also arranged.
  • the guide surface 12 could, if necessary, have cutouts so as not to impede the pivoting process of the flushing pipe 5.
  • FIG. 5 shows a section through the flushing pipe 6 according to FIG. 4 along the dash-dotted line labeled V-V in FIG. 4.
  • the angle 16 between the corresponding radial of the flushing pipe 6 and the guide surface 12 is preferably approximately 45 °.
  • the course of the rinsed base 2 is indicated in FIG. 5.
  • the water flowing in from the right in the illustration of FIG. 5 is directed downwards from the guide surface 12 against the base 2 and forced under the flushing pipe 6, where there is only a small gap between the flushing pipe 6 and the bottom 2, since the flushing pipe 6 is scarce is held above ground 2.
  • the bottom 2 is washed away below the flushing pipe 6 by this flow process.
  • the base material whirled up by the nozzles 11 is carried along by the flowing water.
  • a step 17 forms in the bottom 2, which also progresses in the bottom 2 as the flushing device progresses, so that the bottom 2 is ultimately lowered more deeply by this flushing and flow process.
  • the efficiency of the flushing device is effectively increased by the guide surface 12.
  • the base 2 is leveled by the flow process, in particular the channels 3 caused by the proboscis 1.
