Definitions

  • the invention relates to a dam, in particular for the closure of a tidal water course in the event of a storm surge.
  • Storm surge barriers are systems in tidal waterways, the closures of which are generally open, which on the one hand enables normal tidal waves to swing in and out unhindered and on the other does not affect the passage of ships.
  • the major requirements placed on the passage openings of the barriers include the following: On the one hand, the continuous fairway of at least 200 to 400 m wide and about 12 to 15 m depth under medium low water should not be restricted in any way by the structure. On the other hand, the overall cross-section of the waterway should be changed as little as possible in order to avoid serious effects on the tide course.
  • the invention is therefore based on the object to provide a barrage with a barrage which, even with a correspondingly large dimensioning, the requirements for stability can be produced easily, without significant change in the river cross-section, without expensive construction and without great effort, and ensures reliable and safe function in an emergency.
  • the barrier proposed for the solution consists of locking elements or parts which can be moved on inclined planes and which have the peculiarity of being telescopically pushed into one another.
  • the road inclination to be selected is not only based on the best possible adaptation of the straight inclined path to the irregular river profile. Since the width and height of the navigation channel should not be restricted, the bottom depth of the main fairway at its lateral boundary is a compulsory point for the height of the inclined planes for the closure parts. The low point below the middle of the fairway is then a few meters below the target level for the navigation, whereby the driveway always has a sufficient water level for the draft of large ships even in low water.
  • Pushing the locking parts together in the rest position reduces the space required for the elements when not in use.
  • the closure parts can be completely moved out of the water and pushed together at least above the average flood level.
  • the closure parts can have individual drives and can be moved independently of one another.
  • the storage of the closure parts in their rest position outside of the water is advantageous here. As with the basic bodies, the tidal course is not impaired and gentle and maintenance-friendly storage of each closure part is achieved.
  • the cross section of the closure elements has a triangular shape, the sea side carrying the dam wall and the inner side predominantly absorbing the supporting forces.
  • the baffle walls can be flat or curved, with what a more favorable introduction of the occurring forces into the base body can be connected.
  • the angles between the legs of the closure elements at their upper edge result from corresponding calculations of the frame stiffness according to the local conditions and planning.
  • a right angle at the top leads z. B. to the favorable design of an isosceles triangle with the force system, the dam wall side as a carrier on two supports, which rests below in the carriageway and on top of the rear support structure.
  • Vertical end edges are formed on the closure elements at least where two elements must close in the middle of the river when approaching each other.
  • the upper edge of the elements runs approximately parallel to the inclination of the inclined plane, but not steeper than this, so that the upper edge is higher on the upper side than on the river side, also influenced by the individual length and inclination of the road.
  • the lowest points of the upper edge lie at the height of the highest storm surge water level to be prevented, whereby an occasional wave overturn is accepted.
  • a horizontal solid wall closes the barrier to the shore, the crown of which is at the height of the maximum storm surge water level. In the rest position, the segments are pushed into each other over this wall.
  • each closure element In the closed position, all elements seal against each other and against the sole. Seals between the individual elements and on the sole are arranged so that they only lie fully in the final closed position. In the intermediate positions and in the rest position, on the other hand, they release a flow gap, which is achieved by suitable shaping of the surfaces on which the seals bear. Lowering the carriageways for the closed position of each closure element can also support the effective sealing.
  • the intermediate seals are attached to the inside of each segment on the edge facing the bank. In the closed position, they are pressed against bead-shaped contact surfaces on the baffle wall of the next higher element.
  • the base seal is created by spring plates protruding in front of the baffle wall, which have rubber profiles on their underside, which run along the baffle wall. These sheets are attached to the lower edge of the elements and seal by pressing the water pressure against corresponding contact surfaces.
  • the contact surfaces are located in front of the front track of the respective closure part on the base body.
  • the closure elements run in lanes, with each closure part traveling in its own lakefront and inland lanes.
  • the carriageways are recessed into the base body and have sloping flanks, so that the closure parts are positively centered by the flank slopes during the closing or opening movement.
  • the closure elements For guidance in the raceways or lanes, the closure elements have rollers and, for their failure, auxiliary runners which can also act as wheel break supports.
  • the roles are attached under the legs of the closure elements so that longitudinal and transverse forces can be transferred well into the base body, for. B. at right angles to each other.
  • the flanks of the trough-shaped carriageways, which are loaded by the rollers, are reinforced for this purpose and / or have corresponding internals as supports.
  • the bearings of the rollers can be elastic, which ensures improved smoothness in the event of vibrations.
  • the problem here is the increased rolling resistance due to deposits on the road surface.
  • the barrage according to the invention can of course also be used to shut off river courses.
  • the river water In the blocking position, the river water is dammed up in front of the barrier and prevented from flowing out.
  • This can e.g. B. happen for the purpose of water storage in dry seasons or to protect densely populated areas downstream from flooding.
  • the barrier elements could e.g. B. be hidden in previously provided chambers of the valley walls.
  • a tidal stream 4 has z. B.
  • the bottom 41 indicated by dash-dotted lines in FIG. 1.
  • This river bottom 41 runs steeper towards the bank 42 and is flattened in the middle.
  • the bottom 21 of the watercourse 4 which is indicated in Fig. 2, consists of a base body 2, which forms an inclined plane 22, starting from points above the river bank to the deepest point, which is located approximately in the middle of the river course .
  • the bottom 21 is flatter and is lower in the middle of the river course 4 than the original bottom 41. This peculiarity benefits the fairway 43 lying in the middle of the river.
  • FIG. 2 shows the roadways 23 of the baffle walls 11 and the support walls 12 on the base body 2.
  • a storage wall 11 and a support wall 12 together form a closure element la to ld.
  • the support walls 12 have no covers and have openings between their supports.
  • Fig. 1 shows the sea-side view of the half barrage in the closed position. With 44 the average flood level is indicated and 45 with the maximum.
  • closure elements 1a to 1d overlap one another at their vertical end edges 14 and have seals 15 at the overlap points of the baffle walls which rest on the bead-shaped contact surfaces of the next higher element, not shown.
  • the closure elements 1a to 1d are the same in shape but of different sizes.
  • Your upper edge 13 is inclined according to the inclined plane 22, but can also run differently than shown, for. B. flatter.
  • the elements 1a to 1d are getting smaller from the middle of the river to the bank, marked with the letters a to d. 1 z. B. they are shown very exaggerated.
  • closure elements 1a to 1d use is made, among other things, of drive sticks or toothed racks, and support for the opening movement by means of traction means driven by winches is also contemplated.
  • the required drive machines are housed in the machine house 6.
  • the base body 2 which is made of concrete, is shown in section. It contains, among other things, cable channels and operating aisles 28, not shown, of which one, located in the center of the base body 2, is shown as an example. Under the storage wall side of the closure elements 1a to 1d, the base body 2 is anchored by an additional sealing wall 29 in the subsurface or bottom of the watercourse 21 and is protected against being washed out. The lanes 23 for the retaining walls 12 and baffle walls 11 are located on the base body 2.
  • lanes 23 are designed identically for both baffle and retaining walls 11, 12 and have a trough-shaped cross section 25 with inclined flanks 26 Closure elements la to ld of the same design lower edges 3 with rollers 31 on the flanks 26 of the trough-shaped roadway 23.
  • the flanks 26 have angles of 45 ° and the rollers 31 of the closure elements 1a to 1d are correspondingly arranged at right angles to one another.
  • the arrangement of the rollers 31 or the inclination of the flanks 26 is intended to enable the stowage and support walls 11, 12 to be supported favorably. Further configurations with differently inclined flanks are conceivable, to which the rollers 31 are arranged to match.
  • a combination of differently inclined flanks in a carriageway or carriageway group 23, in each case according to the storage or support wall 11, 12, is also possible here.
  • closure elements 1a to 1d are shown pushed together over the wall 5 in their rest position. Not shown is the seal 15 present on its respective inner side 16 on the front edges 14 (see FIGS. 1 and 2). On the baffle walls 11, the plates 18 are hatched.
  • Fig. 4 shows an enlarged section of the lower edge 3 in a roadway 23.
  • the flank flanks 26 contain embedded reinforcements 24, z.
  • Runners 32 are indicated on both sides, close to the rollers 31, on which a closure element 1 can slide for the rollers as an alternative.
  • a sheet 33 projects on its lower edge 3, on the underside 34 of which a rubber profile 35 is fastened.
  • This profile 35 which runs along the lower edge 3, lies in a bearing surface 27, which runs in front of the roadway 23 in a channel-like manner, in a sealing manner due to the water pressure and thus prevents the penetration of sea water under the dam walls 11.
  • Fig. 5 shows different operating positions a to e of the half barrier.
  • position a all closure elements 1a to 1d are in the rest position above the wall 5.
  • position b is an element, e.g. B. have been extended for maintenance work in front of the others.
  • position c and d show positions of readiness c and increased readiness d in the event of an expected storm surge. Since the flow velocity accelerates extraordinarily with increasing narrowing of the cross-section and an increasing gradient also builds up, which leads to an increasing load on the closure elements 1a to 1d, it should be problematic to have them retract rapidly into the closed position one after the other.
  • Position e shows the barrier in the closed position with the maximum flood level 45 indicated.
  • the sloping upper edge corresponding to the inclination of the road would have to be replaced by a horizontal support structure for the storage of the storage flaps.
  • the flaps which are held approximately horizontally during the retraction of the elements, are only lowered into the inclined position for final closing, which corresponds to the inclination of the storage wall of the other closure elements.
