Definitions

  • the invention relates to hydraulic engineering and in particular to floatable closures of culvert structures, e.g. Protective dikes.
  • a culvert structure in a protective dyke is usually arranged on waterways near larger port cities and can, among other things, be part of existing structures to protect against flooding.
  • Such closures place particularly high demands on their operational reliability not only when closing off a passage opening, but also to a lesser extent when they are opened, which can also be used in emergency situations, e.g. in the event of a leak in the cells, a power failure, etc.
  • a fundamental difference between floatable closures of passage structures for diving equipment, floating docks and submarines is that the floatable closure has to sit on the sole or the basic threshold of a passage opening when immersed.
  • the floatable closure is intended for use in the event of flooding in strong waves, a water level gradient and, as a result, under conditions of strong currents.
  • a floatable closure of a passage structure with a water dam which contains a ballast and bilge system which includes ballast and dry cells.
  • the lower part of the ballast cells is in the floating state of the closure below the water line. Openings with slides for taking water are always made in the bottom sections of the ballast cells (SU-A-242750).
  • ballast cells which have openings in the bottom section with slides for taking water, and dry cells.
  • the lower part of the ballast cells is in the floating state of the closure below the water line.
  • This floatable closure is lowered by opening flood valves and filling ballast cells with water through flood valves in self-flow. To lift the closure, water is removed from ballast cells with the help of pumps.
  • a disadvantage of this float-in closure, as with the one described above, is that it has a relatively low operating reliability, which is due to the following causes.
  • the invention has for its object to provide a floatable closure of a passage structure in which the ballast and bilge system contains such cells and these cells are designed and arranged in relation to each other and on the water line, as well as these cells with the surrounding medium are related to the fact that damage to the water baffle body when it is placed on the basic threshold of the passage opening is excluded and an emergence of the water baffle body is ensured in the event of damage to the ballast cells due to water pouring out of the latter.
  • ballast and bilge system which includes ballast cells which have openings with slides for water drainage in floor sections and dry cells
  • the ballast and bilge system contains additional cells , whose bottoms love no higher than in the level of the dry cell cover, that the additional cells have calibrated openings in their bottom parts, which are below the water level mark on the underwater side in the lowered state of the water accumulation body, and have openings for connecting their internal cavities to the atmosphere above them Brand lie, and that the ballast cells are also arranged above this mark, where openings with slides in the bottom parts of the ballast cells as well as calibrated openings in additional cells on the pressure-free side of the water dam.
  • the water level mark on the underwater side in the lowered state of the water dam body is always understood to mean a predetermined imaginary line on the water dam body, which is on the basic threshold of the passage opening, which corresponds to the maximum expected underwater level.
  • the presence of additional cells ensures the stability of the water accumulation body after dry cells have been completely immersed.
  • the presence of calibrated openings and openings for connecting the internal cavities of these cells with the atmosphere in the additional cells, the execution of these openings below or above the water level mark on the underwater side in the lowered state of the water accumulation body and the execution of the calibrated openings on the pressure-free side of the water accumulation body When flooding the ballast cells, the immersion speed of the water accumulation body can be reduced after the dry cells have been completely flooded, which prevents damage to the water accumulation body when it is placed on the basic threshold of the passage opening and consequently makes the floatable closure more reliable in operation.
  • the reduction in the diving speed of the water accumulation body is due to the fact that water levels in additional cells are always below the underwater level when submerged.
  • the total cross-sectional sum of the calibrated openings Through the choice of the total cross-sectional sum of the calibrated openings, one can achieve an optimal, safe immersion speed of the water accumulation body when it is placed on the basic threshold.
  • the ratio of the immersion speed of the water accumulation body and the total cross-sectional area of the calibrated openings can be determined using known calculation methods.
  • the arrangement of the ballast cells above the underwater level in the lowered state of the water accumulation body ensures that the water accumulation body emerges in the event of damage to the ballast cells due to a water drain from them in self-flow.
  • the invention thus ensures high operational reliability.
  • a floatable closure of a passage structure contains two water dammers 1 (Fig.1), which are designed as wings.
  • An embodiment variant of the floatable closure which contains a water accumulation body is possible.
  • Each water dam 1 is connected to a weir flap 4 by a frame 2 with the aid of a ball joint 3.
  • the closure also contains a drive 5 for extending the water accumulation body 1 into the passage opening 6 and for pulling it into a recess 7.
  • the ballast and bilge system is arranged inside the water accumulation body 1 and consists of dry cells 8 (FIGS. 2, 3 and 4 ) with a floating material, e.g. Foam 9 filled and arranged in the area of the swimming water line 10 (FIG. 2) in the floating state of the water dam body, ballast cells 11 and additional cells 12.
  • the ballast cells are above the mark of the water level 13 (FIG. 3), which is on the side of the underwater 14 is in the lowered state of the water accumulation body 1, ie in its position on the basic threshold 15 of the passage opening 6 (FIG. 1) and have openings 16 (FIG. 4) in their bottoms for water drainage with slides 17.
  • the slides 17 are provided with electric or manual drives 18, which are arranged in dry, heated rooms 19.
  • the additional cells 12 are arranged in the end regions of the water accumulation body 1 in such a way that they ensure stability (the desired trim position) of the water accumulation body after the dry cells have been fully immersed. Bottoms of the additional cells 12 are no higher than in the plane of the cover of the dry tariffs 8.
  • Calibrated openings 20 are made in the bottoms of the additional cells 12, which are connected via filler neck 21 to outside water on the pressure-free side 22 of the water dam body 1.
  • Openings 23 are made in the covers of the additional cells 12, by means of which the inner cavities of these cells are connected to the atmosphere.
  • the calibrated openings 20 are arranged below the mark of the water level 13 and the openings 23 above this mark.
  • Openings 24 in the ballast cells 11 connect inner cavities of these rows to the atmosphere on the pressure-free side 22 of the water accumulation body 1 via (not shown) connectors.
  • Inner hollow space me of the additional cells 12 can be connected to the atmosphere via the openings 23 also on the pressure side of the water accumulation body, but sockets with a long length should be used because an upper water level can significantly exceed an underwater level.
  • the floating closure works as follows.
  • the slide 17 is opened, after which water flows out of the ballast cells 11 through the openings 16 to the underwater side. Water also flows out of the additional cells 12 on the underwater side independently via the calibrated openings 20.
  • the floatable closure of a culvert structure according to the invention is generally intended for arrangement on waterways in the vicinity of larger port cities and can, among other things, belong to the existence of structures for flood protection.
