Definitions

  • the present invention relates to an exceptional spillway for dams and similar structures of the type comprising two spillway devices, including a device sized for common floods, the other device being constituted by a spillway threshold whose crest is located at a first predetermined level lower than a second predetermined level corresponding to a maximum level or highest water level for which the dam is designed, the difference of said first and second levels corresponding to a predetermined maximum flow of an exceptional flood, and a moving rise closing said threshold.
  • valves must close off the entire overflow threshold, but that most of them could remain closed almost permanently in the absence of exceptional floods and only open every 20 or 50 years for example.
  • other evacuation device allows the evacuation of the most frequent floods (such as for example bottom, middle bottom or surface evacuators, winnowed or not, where the water intake of a factory hydroelectric, or any other water evacuation device)
  • all of said valves could remain closed almost permanently.
  • valves because their nature, remains an important cause of dam failure. These valves therefore have the drawback of poorer operational safety than free overflow thresholds; moreover they are expensive.
  • a fusible dam section leveled at a lower level than that of the rest of the structure and operating according to the principle of the erosion of its constituent materials, erosion which is generated by a extreme rise in the level of the reservoir during a flood of very exceptional importance.
  • the purpose of this fusible dam is to avoid the uncontrolled and catastrophic discharge of an extreme flood on the whole of a structure, by concentrating the effects of the flood on a section specially equipped to break by erosion and thus offer additional evacuation capacity. After the rupture of the fusible dike, major repair work would be necessary to allow normal operation of the structure again. On the other hand, opening a fusible dam can lead to too rapid an increase in the downstream flow.
  • the problem that the present invention seeks to solve is to close almost permanently, at a cost much lower than that of the valves and at a higher height than before, all or part of a free overflow threshold while allowing , in a completely reliable way, the evacuation of exceptional floods, without external intervention and without major modification of the structure.
  • the present invention therefore constitutes an economical substitute for the fraction of valves intended solely for discharging the least frequent floods.
  • the riser comprises at least one rigid and massive riser, which is placed on the crest of the overflow threshold and is held in place thereon by gravity, said raising element having a predetermined height at least equal to the difference of the first and second predetermined levels and being dimensioned in size and weight so that the moment of the forces applied by the water at the riser reaches the moment of gravity forces which tend to hold the riser in place on the overflow threshold, and that consequently said riser is unbalanced and driven out when the water reaches a third predetermined level at most equal to the second predetermined level.
  • the raising element (s) can be manufactured at a moderate cost compared to the valves and, in the case where they are installed on the threshold of an existing dam, this installation, possibly joined to the installation of the valves, can be made without major modifications to the overflow threshold of the dam, such as we will see it later.
  • a stop of predetermined height is preferably provided on the threshold overflowing at the foot of the raising element, on the downstream side thereof, to prevent it from sliding towards the downstream on the threshold, without however preventing it from tipping over the stop when the level reaches said third predetermined level.
  • the height of the stop is taken into account as will be seen below for the dimensioning in size and weight of the raising element or elements.
  • a seal may be disposed between the overflow threshold and the base of the riser, near the upstream edge of said base.
  • a seal is not absolutely essential if, in the absence of a seal, water leaks between the raising element and the overflow threshold are low and if the area of the overflow threshold on which the said elevation element (s) rests is suitably drained so that no appreciable underpressure can be established under the said elevation element (s).
  • means may be provided for automatically establishing an underpressure under the said elevating element or elements when the water level reaches said third predetermined level, in order to promote the imbalance and tilting of said elevating element or elements at the time where it becomes essential to evacuate an exceptional flood.
  • the invention can be applied both to the spillway of an existing dam and to that of a dam under construction.
  • the crest of the overhanging threshold can be leveled off at a level lower than said first predetermined level and the one or more raising elements are placed on the leveled threshold and plug it. It is thus possible to obtain greater security than with the undisturbed overflow threshold, since the opening which is obtained after tilting of the elevating element or elements has a greater height than in the case of an undisturbed overflow threshold. , thus allowing to evacuate a higher flood flow than the maximum flow of the exceptional flood for which the dam was originally designed.
  • the choice of the difference between the first and second predetermined levels will result from an optimization between increase in safety, reduction in the cost of the works and possible increase in the cost of the valves located on the spillway.
  • each increase element or a group of elements of rise can be dimensioned so as to tilt for a predetermined water level lower than that to which another element or group of rise elements will tilt, the latter being itself dimensioned so as to tilt for a higher water level lower than that to which a third element or group of rising elements will switch, and so on. In this way, a gradual increase in the evacuation capacity is obtained, if necessary, depending on the extent of the flood.

  • the number of elevating elements 11 is not limited to five elements as shown in Figures 3a and 3b, but can be smaller or larger depending on the length of the weir 5 (measured in the longitudinal direction of the dam) .
  • the number of elevating elements 11 is chosen so as to obtain low unit masses allowing easy installation and replacement of said elevating elements.
  • Each rising element 11 has a height H1 greater than RM, is placed on the overflow threshold 6 and is held thereon by gravity.
  • each rising element 11 is retained against any sliding downstream, by a stop 12 located at the foot of the element 11, on the downstream side thereof.
  • the stop 12 can for example be embedded in the threshold 6, as shown for example in Figure 4a, and it can be discontinuous as shown in Figures 3a and 3b. However, if desired, the stop 12 could be continuous.
  • the height of the stop 12 is predetermined, but it can be variable depending on the forces involved and according to the water level from which it is desired to initiate the tilting of each rising element 11.
  • seals 13 are also provided between the vertical side walls, two by two opposite, adjacent elevation elements 11 as is also visible in Figure 3b.
  • a seal 15 is also provided between the overflow threshold 6 and the base of the elevation elements 11 near the upstream edge 16 of said base as is for example visible in Figures 4a and 4b.

  • a drainage system can be arranged continuously in the overflow threshold 6, in the zone of the latter underlying upward 10, in order to dry out this zone and to avoid that, under normal service, an underpressure is applied to the elevating elements 11.
  • a dam in the case where a dam would include a free overflow threshold as the only device for discharging floods, it is possible to envisage equipping only part of this threshold with one or more valves v and the remaining part of a rising fuse 10 according to the invention.
  • a dam in accordance with the invention is thus obtained with a single overflow threshold 6 of which two evacuation devices are associated, one (7) equipped with at least one valve V for the evacuation of current floods, the another equipped with the 10 fuse riser for the evacuation of exceptional floods.
  • each rising element 11 is dimensioned so as to be self-supporting for a water load lower than a predetermined level N, itself at most equal to the maximum level RM of the highest admissible water in the dam.
  • a predetermined level is equal to the level RM, as long as the level of water remains lower than the level RM for floods of low or average importance the water is retained by the increases as shown in FIG. 4a without the rise is not destroyed.
  • the water level reaches, in the aforementioned hypothesis, a predetermined level N equal to or slightly lower than the maximum level RM in the case of a severe flood or exceptional flood or damage in the operation of the device 7, at least one element 11 of the rise 10 is unbalanced under the thrust of the water and rocks around the stop 12 as shown in FIG. 4b and the element or elements 11 which are tilted are evacuated by the water of the flood at least up to the foot of the weir 5, thus allowing the evacuation of the strongest floods. After evacuation of a strong flood having caused the tilting of the rise 10, the water level returns to the level of the normal reservoir RN or to a lower level still.
  • the dams and overflow weirs are dimensioned so that the level of the lake (level of the reservoir) reaches the maximum level RM for the exceptional flood envisaged (project flood).
  • This flood can for example be the flood occurring only one year in a thousand (millennial flood).
  • the height H of the sheet of water necessary to evacuate the flow of the fraction of the project flood that the device 7 does not evacuate corresponds to 20 m3 / s per linear meter of threshold,
  • the threshold 6 can then be fitted with risers in accordance with the present invention, the height of which is greater than or equal to 5 m.
  • the tilting of the elevation element (s) 11 and, consequently, their destruction depends on the balance between, on the one hand, the motor moment, that is to say the moment of the forces which tend to overturn the elevation element considered, and, on the other hand, the resistant moment, that is to say the moment of the forces which tend to stabilize the said rising element.
  • a trigger device directly linked to the water level to trigger the tilting of the raising element with precision for a predetermined water level, the water height corresponding to the above-mentioned equilibrium cannot be fixed only with a margin of uncertainty of up to 0.2 m. Under these conditions, it is necessary, for safety, to reduce the tilting height of the elevation element (s) 11 by an amount corresponding to this margin of uncertainty, for example 0.2 m. However, this uncertainty can be reduced by providing a trigger device which will be described later with reference to FIG. 7.

  • B denotes the height of the stop 12 above the threshold 6
  • z denotes the water level.
  • the driving forces that tend to tilt the elevating element 11 are the thrust P of the water on the upstream face of the elevating element 11 and the underpressure U which is possibly exerted on the base surface of said elevating element and which is due to the existence of possible leaks at the seals or to the presence of a trigger device which will be described later.

  • the 7 is essentially constituted by a pressurization pipe 21 which , in normal service, puts the area underlying the rising element 11 in relation to the atmosphere, the upper end 21a of the pressurization pipe 21 being situated at a level equal to or lower than the level N for which it is desired that the tilting of the elevating element 11 occurs (the difference between the level of the top of the pipe and the level N corresponding to the height of the sheet of water pouring into the pipe and necessary for its filling),

It is clear that according to the value of the pressure applied by the device 24, the tilting of at least one of the raising elements 11 is only possible from the moment when the water has reached a certain level in the detention. This device facilitates a premature selective tilting of the rising elements 11 to prevent a very strong flood for example.
  • This solution must in particular allow, when an exceptional flood is announced, to start emptying the tank in advance by voluntarily and / or automatically causing the tilting of at least one rising element 11 and reducing on the one hand the number of elements which will have to switch during the full effect of the flood on the rise 10, and on the other hand the maximum flow of the flood downstream.
  • the probability of opening of the increase 10 is not modified but, in the event of an exceptional flood, the flow section available after total destruction of the increase 10 is notably increased for the same water level in the reservoir, which makes it possible to safely evacuate a flood having a flow rate much higher than that of the flood for which the structure was originally dimensioned.
