Definitions

  • the present invention relates to a fuse-up for a hydraulic structure such as a weir in a river, a spillway over a dam or a protective dyke comprising a structure forming a watertight or substantially water-tight wall, installed on said hydraulic structure and maintained on it by gravity , and can be erased so as to allow the water to pass unobstructed, said structure being sized in weight and size to be expelled by the water when the latter reaches a predefined level.
  • Fusible heaters of this type are well known and are installed in the usual way on the crest of a threshold disposed across a tank in order to raise the water level of the tank upstream of said threshold. Installed on the threshold of a dam, they make it possible to raise the level of reservoir retention or to improve the safety of the dam in the face of floods. They may also be installed on the weir of a dike bordering a river and be intended to protect neighboring areas against floods, the weir being in this case installed on the dike at a chosen location so that in case of water flows into a temporary storage tank or a safe area chosen for other areas adjacent to the river.
  • the fusegates can be of the non-spill type or of the overflow type, ie in the latter case, they can let a certain amount of water over their ridge when the water level upstream of the rise is greater than the retention height h RN of the ridge and as long as this water level does not exceed a predefined height h MAX . In any case, the fusegates must be erased if the water level upstream of the rise reaches a predefined level MAX during a flood, in order to release the volume of water that it retains in the water. reservoir, and thus avoid a flooding of water from neighboring regions upstream or damage to the dike or dam.
  • Fusible hoists apply in particular to a dyke or dyke or embankment dam, or to a dyke or mixed dam constructed partly of backfill and partly of concrete or masonry.
  • the dike can be a dike across a stream, or a dike along a stream to protect the surrounding land from flooding.
  • a dam it can be any type of dam creating a water reservoir, or a dam associated with the neck dam aforementioned.
  • breaking points which in the event of exceptional events, such as exceptional floods threatening the destruction structure, yield in predetermined locations of the structure chosen for Damage to the structure itself and / or to people or property flooded by the structure being broken is minimal.
  • These breaking points can be formed using fusegates located on the crest of the portion of the dike, backfill or dam chosen, or other system for evacuation of the required flows.
  • Such an increase comprises at least one rigid and massive rising element which is placed on the crest of the pouring threshold and is held in place thereon by gravity, said rising element having a predetermined retention height RN RN and being dimensioned in size and weight so that the moment of the forces applied by the water to the raising element reaches for a certain predefined level h MAX , the moment of the gravitational forces which tend to keep the raising element in place on the threshold discharging and as a result said rising element is unbalanced and driven out when the water level upstream of the rise reaches the predefined level h MAX .
  • the water can be evacuated by the valves and other devices sized for the most common flows, without resulting in a destruction of the rise and therefore without the weir ceases to be closed by said rise.
  • the level of the water reaches the predefined level MAX of imbalance of the rise and one or more elements of rise are automatically unbalanced and driven out by the water under the sole action of the water forces, so without any outside intervention being necessary, thus giving the threshold its full evacuation capacity.
  • means are provided for generating a pressure, known as underpressure according to the terminology allowed by the hydraulicians, in a chamber formed under the rising element or elements, when the water level reaches the predefined level h MAX of imbalance of the rise.
  • Such means may advantageously be arranged so that the underpressure applied in the chamber of the raising element remains zero or very low as long as the level of the water remains below the predetermined level h MAX , and for a sub substantially higher value pressure is suddenly applied to the rising element at the moment when the water level reaches said predetermined level, the dimensioning of the elements being such that at this moment the destabilizing motor moment becomes greater than the stabilizing moment.
  • Such means are in particular constituted by a conduit called a well having a lower end which opens into said chamber and an upper end which is located at a level corresponding to said predefined level.
  • Such a device may consist of a funnel whose upper edge is at a level higher than the predefined level as described in the patent applications.
  • the bell shape covering the upper end of the duct does not offer sufficient guarantees against the risk of obstruction by floating debris or by waves. Indeed, for this embodiment, in normal operation, that is to say when the water level is less than or equal to the retention height h RN of the rise, the water inlet opening the bell is located above the water level, so that floating debris can obstruct the water inlet where the well itself and in addition the well remains accessible to potential vandals.
  • the fuse heats described above remain subject to the following degraded operating causes: vandalism, in particular the theft of metal parts, effects related to large waves that can trigger the rocking of the rise while the level n ' is not really achieved, and the shutter means pressurizing floating debris on the surface of the water.
  • the setting of the predefined height of tilting of the rises is not precise.
  • the water level of the reservoir or watercourse is significantly higher than the height of retention h RN of the rise (cf. figures 9 )
  • the water level tends to decrease, a height ⁇ h, approaching the rise, due to the increase in the flow velocity of the water in the channel 14 connecting the reservoir of water at the pouring threshold.
  • the object of the present invention therefore has the main object of proposing an increase overcoming the problems of the prior art mentioned above, whose sensitivity to the problems of vandalism and aggression by external natural phenomena is less and whose the operation is optimized, and allowing, in particular, a finer regulation of the height of tilting of the rises.
  • the water intake that is to say the water inlet opening in the structure is located under the ridge of the rise.
  • the fuse-up for a hydraulic structure such as a river sill, a spillway over a dam or a protective dyke, includes a massive element disposed on the crest of the structure and held on it by gravity forming a watertight or substantially watertight wall, installed on said hydraulic structure and being able to be erased so as to allow the water to pass unobstructed when the level reservoir or stream reaches a predefined level, a chamber being formed at the base of the solid element between it and the surface which supports it, pressurizing means for filling the chamber with the water to create under the massive element a thrust directed upwards when the water of the reservoir or stream reaches the predefined level, characterized in that these pressurizing means consist of a hold of water at a feed structure provided with two compartments defined by an inner vertical wall, the two compartments being in communication with each other by at least one passage formed in part ha of the intake, one of the compartments having one or more openings in its lower part allowing the entry of water from the reservoir or the water
  • the water inlet opening in the feed structure is immersed.
  • the entry of water into the pressurizing means is effected regularly from a submerged opening, in the lower part of the feed structure, so that all the risks of obstruction of the entry of the pressurizing means by floating debris to the surface of the water are avoided because they are below said surface.

  • a finer regulation of the level of water in the upstream reservoir is obtained during episodes of flood. It is also possible to delay the rocking of the first rise because the tilt level difference between the feed structures is reduced.
  • the water level on the spillway decreases due to the increase in flow velocities on the sill and it is difficult to make a well that allows the lower chamber to be lowered. pressure for higher water levels in the tank.
  • An adequate configuration of the feed structure of the hoists according to the invention with a water intake on the front face makes it possible to generate a pressure (H) resulting from the static pressure corresponding to the water level on the weir (h e ) and the kinetic pressure corresponding to the speed of the flow of water on the weir (v 2 / 2g).
