Definitions

  • the present invention relates to a spillway spillway for dams and similar structures, of the type defined in the preamble of claim 1.
  • Patent US-2 118 535 describes a system similar to the previous one, but in which the rise, produced in the form of a single rigid plate of wood, metal or other material, is connected to the threshold of the spillway by an articulation of horizontal axis allowing the plate to pivot down and downstream when the stakes which support it bend.
  • the barrier with free overflow threshold offers compared to a work provided with valves the best safety vis-a-vis the hydrological hazard which remains one of the major risks for the dams.
  • valve systems which close the overflow threshold when the valves are closed.
  • the valves of whatever nature, conventional or inflatable, of automatic or manual operation, are generally of a fairly high investment cost and they require periodic maintenance and maneuvers. They also require continuous human monitoring or a controlled mechanism reacting to the water level of the reservoir, a mechanism which is often expensive and sophisticated and which is never completely immune to failure.
  • the operational safety and reliability of a gated structure is lower than that of a structure with a free overflow threshold (not gated).
  • the storage capacity of the dam is increased by an amount corresponding to the height of the raising element or elements.
  • the raising element (s) can be manufactured at a very moderate cost compared to the valves and, in the case where they are installed on the overflow threshold of an already existing dam, this installation can be done without the need for d '' make major modifications to the overflow threshold of the dam as we will see below.
  • the plate forming each raising element can be engaged in a groove provided in the threshold itself or in a mounting piece rigidly fixed to the threshold.
  • the plate forming each raising element can have, in transverse vertical section, a substantially L-shape and its horizontal branch can be rigidly fixed to the threshold for example by a bolted connection of the embedding type. Sealing at the base of the plate can be ensured by filling the embedding groove with a suitable filling material, or by a suitable seal or by both.
  • seals can also be arranged between the vertical edges of the plates
  • 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 is preferably leveled at a level lower than said first predetermined level and the one or more rising elements are embedded on the leveled threshold.
  • the storage capacity of the dam can be kept equal to that it had before the overflow threshold was lowered, or it can be increased depending on whether the elevating element or elements are given a height such as their sound or their vertex finds at said first predetermined level, or at a level higher than this, but lower than said third predetermined level.
  • each riser or a group of risers can be dimensioned so as to bend for a predetermined water level lower than that at which another element or group of risers rise will fold, the latter itself being dimensioned so as to fold for a lower water level than that to which a third element or group of rise elements will fold, and so on. In this way, a progressive increase in the evacuation capacity is obtained, if necessary, depending on the extent of the flood.
  • Figure 1 is a perspective view showing a structure, such as a dam, and its outlet spillway floods with a free discharge threshold, to which the invention can be applied.
  • Figures 2a and 2b show, in vertical section and on a larger scale, the crest of the free overflow threshold of the dam of Figure 1 for two different water levels.
  • Figure 3 is an elevational view of the weir of Figure 1, seen from the downstream side and equipped with a fusible link implemented in the present invention.
  • FIG. 4 is a plan view of the weir of FIG. 3.
  • Figure 4a is a view similar to that of Figure 4, showing another possible arrangement of the elements of the fuse riser implemented in the invention.
  • FIG. 5 shows, on a larger scale, a horizontal section of a seal that can be used between two adjacent elements of the riser of FIGS. 3 and 4.
  • Figures 6 and 7 show, on a larger scale and in vertical section, two embodiments of the embedding of the rising elements.
  • FIGS. 8a to 8e are views in vertical section making it possible to explain the operation of the fuse riser implemented in the present invention, before, during and after the passage of a flood.
  • Figures 9a and 9b are graphs showing the forces which, in service, can be applied to a riser used in the present invention.
  • FIG. 10 is a graph representing the variations of the moments of the driving and resistant forces as a function of the height of water above the overflow threshold, as well as the variations of the flow of water discharged as a function of the height of the overflow blade.
  • FIG. 11 is a view in vertical section showing a lifting element used in the present invention, with which is associated a folding trigger device.
  • FIGS. 12a to 12c show, on a larger scale, various protective devices which can be provided at the upper end of the trigger device of FIG. 13.
  • Figures 13a to 13c are cross-sectional views for comparing the maximum heights of overflow blades in the case of the present invention for risers having different heights ( Figures 11a and 11b) and in the case of a threshold known free discharge ( Figure 11c).
  • FIGS. 14a to 14d are views in vertical section making it possible to explain the operation of a double fusible riser according to another embodiment of the invention.
  • Figures 15 to 17 show, in vertical section, other embodiments of a lifting element used in the present invention.
  • FIG. 18 is a perspective view showing a detail of the raising element in FIG. 17.
  • the structure 1 shown in FIG. 1 can be an embankment dam or a concrete or masonry dam.
  • the invention is not limited to the type of dam shown in FIG. 1, but that, on the contrary, it can be applied to any type of known dam with a free overflow threshold. .
  • the reference number 2 designates the crest of the dam, the number 3 its downstream facing, the number 4 its upstream facing, the number 5 a spillway spillway, the number 6 the weir threshold 5 and the number 7 an evacuation channel.
  • the spillway 5 can be located in the central part of the dam 1 or at the end of it or even excavated on a bank without this altering the possibility of using the invention.
  • the level RN of the normal reservoir in operation is that of the crest 8 of the overflow threshold 6. This level RN determines the maximum volume of reservoir that can be kept by the reservoir formed by the dam.
  • the vertical distance R, called revenge, between the crest 8 of the weir and the crest 2 of the dam is the sum of two terms, namely, on the one hand, an increase h1 in the water level due to a flood, up to a maximum level RM or highest water level (PHE), allowing the discharge of the maximum flood ( Figure 2b) for which the structure is dimensioned, and, on the other hand, an additional height h2 intended to protect the ridge 2 of the dam against the oscillations of the water level at its maximum level RM (effect of wind, waves, etc.)
  • the reservoir portion located between the normal retention level RN and the maximum level RM is not stored and is therefore lost for operation.
  • One of the aims of the invention is to enable the level of normal exploitation of the reservoir to be raised almost permanently, and therefore to increase its storage capacity, except during the passage of exceptional floods.
  • the invention provides for fixing by embedding on the overhanging threshold 6 a rise 10, constituted by at least one element 11, in the form of a plate, for example five elements 11a-11e as shown in FIGS. 3 and 4 , said rise 10 or the rise elements 11 being able to resist, without breaking, the water load corresponding to a moderate spill (allowing the passage of the most frequent floods) and being rendered fusible by folding around a installation line for a predetermined water load corresponding to a level N at most equal at the maximum level RM and then allowing the passage of the strongest floods.
  • a rise 10 constituted by at least one element 11, in the form of a plate, for example five elements 11a-11e as shown in FIGS. 3 and 4 , said rise 10 or the rise elements 11 being able to resist, without breaking, the water load corresponding to a moderate spill (allowing the passage of the most frequent floods) and being rendered fusible by folding around a installation line for a predetermined water load corresponding to a level N at most equal at the maximum level
  • the number of elevating elements 11 is not limited to five elements as shown in Figures 3 and 4, but may 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.
  • a conventional seal 13 for example made of rubber, is provided at each of the two ends of the riser 10 between it and the lateral flanks 14 of the weir 5.
  • seals 13 (FIG. 5) are also provided between the vertical lateral edges, two by two facing each other, adjacent elevation elements 11 as is also visible in FIG. 4. All the seals 13 must be such that they do not prevent the folding of the elevating elements 11 relative to one another and relative to the lateral flanks 14 of the weir 5 when it is made necessary for the evacuation of a flood. important.
  • Each elevating element 11 is constituted by a plate made of a metal (suitably protected against corrosion) or other material capable of being folded. At its lower end, the plate 11 can be engaged in an embedding groove 12 formed in the threshold 6 of the weir 5, the groove 12 having a width slightly greater than the thickness of the plate 11 as shown in the figures 6 and 7.
  • the seal at the base of the plates 11 can be ensured by a seal 15 disposed between the threshold 6 and the lower part of the plates 11, for example on the upstream side thereof, and / or by a filling material 16, such as by example of sand, put in the groove 12 on either side of the plates 11.
  • the embedding line 17 around which the elevation elements 11 will bend can be materialized by a support member, continuous or disconstinu, disposed on the downstream side of the elevation elements 11; said support member may be constituted by a longitudinal bar 18, fixed to each elevating element 11, or by a spoiler 19 fixed to the masonry of the threshold 6 in the region of the downstream edge of the groove 12.
  • the elevating elements 11 may comprise, in one or both of their faces, at the level of the embedding line 17, a weakening (not shown) in the form of a groove, continuous or discontinuous, which facilitates the folding of the raising element 11 around the line 17 under a predetermined force.
  • the crest line of the rise 10 is no longer straight, but broken, in a crenelation, so that the length of discharge over the rise 10 is notably increased, which allows, as will be seen below, for a given water level and a given evacuation rate, to reduce the height (thickness) of the overflow blade, therefore to increase the height of the rise and consequently further increase the water storage capacity of the dam .
  • the increase 10 of the present invention makes it possible to raise the level of the normal retention of the level RN (level of the normal retention of the free overflow threshold 6, that is to say without the increase 10) up to the level RN 'corresponding to the height of the rise 10 above the threshold 6.
  • each rise element 11 is dimensioned so as to resist bending for a water load of less than one predetermined level N, itself at most equal to the maximum level RM already mentioned above.
  • said predetermined level is equal to the RM level
  • the water level remains below the RM level for low or medium-sized floods and is between the RN 'and RM levels, the water spills over the rise 10 as shown in figure 8b, without the rise being destroyed.
  • the water level drops to level RN 'or to a lower level if water is drawn into the reservoir.
  • the risks of malfunction due to floating bodies can be easily eliminated by upstream protection using conventional techniques adaptable to each particular case.
  • the protection can for example be constituted by floating lines on the reservoir, at a certain distance upstream from the weir, or by stop devices fixed on the upstream facing of the dam.
  • 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 may for example be the flood occurring only one year in a thousand (millennial flood).
  • the flow of this project flood is for example 200m3 / s and that the free spillway threshold 6 is 40 m long.
  • the height H of the water layer necessary to evacuate the flow of the project flood corresponds to 5m3 / s per linear meter of threshold.
  • the level of the threshold 6 of the weir 5 is leveled 2 m below the maximum level RM to allow the evacuation of the millennial flood, and we lose therefore a useful volume of water corresponding to a 2 meter section.
  • the level of the normal reservoir RN ' is raised to 1.20 m above the level of the normal reservoir RN of the overflow threshold 6 free, that is to say without the elevating elements 11.
  • elevation elements 11 having a height greater than 1.2m the height of the admissible sheet of water will be less than 0.8m and it will be necessary to allow the destruction of the elevation elements, for example every 10 years, but the level of normal restraint will be further increased.
  • elevation elements 11 having a height less than 1.2m we can admit a sheet of water having a height greater than 0.8m, the elevation elements being then destroyed only all 50 or 100 years, but the level of normal withholding will then be lower than in the previous cases.
  • the choice of the height of the elevating elements 11 is therefore essentially an economic choice. In general, it is probably desirable to fix the time interval between two successive total destructions of the fusible riser at approximately 20 years, which would lead to a theoretical height of 1.2 m for the augmentation elements in the example considered here.
  • the destruction of the first element 11c by a medium-sized flood may be sufficient for the flow of the flood without additional rise in the water level, which avoids the destruction of the other elements 11a, 11b, 11d and 11e .
  • the margin of 10 cm which is thus taken is added to the maximum admissible overhanging blade height, so that the height of the rising elements and, consequently, the slice of water gained (RN'-RN) becomes equal at 1.1m (2m-0.8m-0.1m) in the example considered here.
  • the folding of the elevation element or elements 11 and, consequently, their destruction depends on the balance between, on the one hand, the motor moment Mm, that is to say the moment of the forces which tend to bend the rising element considered, and, on the other hand, the resistant moment Mr, that is to say the moment of the forces which oppose the folding of said rising element to the embedding. If a trigger device, directly linked to the water level, is not provided to trigger the folding 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 0.2m.
  • the flow rate of 50m3 / s considered in this example to reduce the height of the maximum permissible overhanging blade before folding the lifting elements to less than 0.8m, by ensuring that the crest line of the elements 11 of the rise 10, considered together, is no longer disposed parallel to the crest of the overflow threshold 6, but along a non-rectilinear line, for example a broken line as shown in FIG. 4a, to lengthen the length of discharge of the flow mentioned above. If this length is doubled, the flow rate of 50m3 / s is then distributed over 80m instead of 40m and the height of the corresponding maximum admissible blade is reduced from 0.8m to 0.5m. This allows, all other things being equal, to raise the height of the elevating elements 11 by 0.3 m and to consequently increase the volume of water stored in the reservoir.
  • Figures 9a and 9b show the forces which, in service, can be applied to a riser 11 of the present invention.
  • the element 11 in the form of a plate, has a thickness e and a height H les above the threshold 6.
  • RM designates as before the maximum level
  • H2 denotes the height of the maximum permissible overhanging blade above the raising element 11
  • z denotes the water level.
  • the driving forces, which tend to bend the raising element 11, are the thrust P of water on the upstream face of the raising element 11.
  • the resistant forces, which oppose the folding of the elevating element 11, are the inherent resistance of the elevating element 11.
  • ⁇ w is the density of water and ⁇ a is the elastic limit of the material used for the construction of the rising element, for example steel.
  • This triggering device essentially consists of a vent pipe 24 which, in normal service, places the space between the plates 11 and 21 in relation to the atmosphere, the upper end 24a of the pipe vent 24 being located at a level N equal to the level for which it is desired that the folding of the plate 11 occurs.
  • the pipe 24 can be bent and pass through the plate 21 as shown in FIG. 11.
  • An orifice 25 having a smaller cross-section than that of the pipe 24 is provided at the lower part of the downstream plate 11, near the threshold 6 , to evacuate the space between the plates 11 and 21 the water due to possible leaks at the joint 22 or the water which could enter through the upper orifice of the pipe 24, because of the waves, before the level of water has actually reached level N.
  • vent pipe 24 is associated with each rising element and each pipe 24 extends upwards to a level N equal to the level N1 or N2 or RM for which the corresponding element must bend.
  • each vent pipe 24 can be equipped with a device for protection against floating bodies, so as not to be blocked by them, or with a device for protection against waves, so that one or more successive waves do not inadvertently trigger the folding of the plate 11.
  • Such protection devices are shown in Figures 12a to 12c.
  • the protection device of FIG. 12a essentially consists of a funnel 26, the upper edge 26a of which is at a level higher than the level N and which has at least one small hole 27 at a level lower than the level N.
  • the protection device consists of the pipe 24 itself, the upper end of which is bent in the form of a siphon 28.
  • the protection device of FIG. 12c consists of a bell 29 , which covers the upper end 24a of the vent pipe 24 and of which the vertex 29a is at a slightly higher level than the level N.
  • the overflow threshold 6 of which was initially leveled depending on the project flood initially chosen, at a level determining the level of the normal reservoir RN (FIG. 13c), to level the threshold 6 a few decimeters below its current coast (corresponding to RN) and to embed on the leveled threshold 6 a fuse increase 10, in accordance with the present invention, composed of at least one increase element 11 dimensioned in height and thickness as described above to fold around line 17 when the water level reaches a predetermined level at most equal to the maximum level RM corresponding to the project flood.
  • 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 pass a flood having a flow rate much higher than that of the flood for which the structure was originally dimensioned.
  • the height chosen for the elevating elements 11 is equal to the leveling height of the threshold 6 (FIG. 13a)
  • the plate 21 remains upright ( Figure 14c) and the normal retention level is only partially reduced (RN''instead of RN' before folding the plate downstream 11). If the folding of the plate 11 was not sufficient to evacuate the flood and if the water level reaches a second predetermined level N2 (N1 ⁇ N2 ⁇ RM), the upstream plate 21 in turn folds as shown on the figure 14d. After folding of the plate 11 and, if necessary, of the plate 21 and after evacuation of the flood, the plate or plates 11 and 21 can be replaced by unfolded plates.
  • each plate 11 (or 21 or 31) forming a raising element was engaged in a groove provided in the threshold 6.
  • the plate 11 (or 21 or 31) can be engaged in a groove formed in a mounting part 32, continuous or discontinuous, which is itself rigidly fixed to the threshold 6, for example by means of bolts and threaded rods 33 sealed in the masonry of the threshold 6 as shown in Figure 15.
  • the threshold 6 is leveled at least by an amount corresponding to the height of the mounting piece 32.
  • the embedding can be carried out as shown in Figure 16.
  • the plate 11 ' seen in vertical section, is curved in the shape of L and its horizontal branch 11'a is rigidly fixed to the threshold 6 by a connection of the embedding type, that is to say a connection where no movement relative is only authorized, for example by means of several bolts and threaded rods 33 (only one is visible in FIG. 16) sealed in the masonry of the threshold.
  • a connection of the embedding type that is to say a connection where no movement relative is only authorized, for example by means of several bolts and threaded rods 33 (only one is visible in FIG. 16) sealed in the masonry of the threshold.
  • straight vertical plates can be used, like the plates 11 of FIGS. 8, 13, 14, 15, which are then rigidly fixed to the threshold 6 by brackets, the vertical branches of the brackets being fixed to the plates for example by welding, while that their horizontal branches can be fixed to the threshold 6 in a manner similar to that shown in Figure 16.
  • FIG. 17 shows, in vertical section, an elevation element 11 composed of two plates 11i and 11j which are removably stacked one on the other. If desired, several plates 11j can be provided and stacked one on the other. Plates 11i and 11j can be held together by at least two pairs of plates 34, one pair of which is visible in FIGS. 17 and 18, which are rigidly fixed to one of the two plates 11i and 11j and which straddle the other plate. Instead of the plates 34, it is also possible to use bars extending over the entire length of the plates 11i and 11j. A seal 35 is provided between the plates 11i and 11j and, if necessary, between the plates 11j when there are several.
  • the plates can all have the same vertical dimension or different vertical dimensions; for example, the upper plate 11j has a smaller vertical dimension than that of the plate 11i.
  • the height of the rise 10 depends on an economic choice, on the desired progressiveness in the folding of the various rise elements, on the precision of the water level at which the folding (precision which can be improved by providing a trigger device as described above with reference to Figure 11) and the shape of the peak line of the rise, line which can be straight or square.
  • the height of the resulting rising elements can vary between 0.9m and 1.5m, allowing, depending on the options taken, to gain between 45 and 75% of the slice of water which would be lost without the use of the fusible link.
  • the fuse increase implemented in the present invention allows to substantially and almost permanently increase the storage capacity of a dam or other structure with a free discharge threshold, while maintaining or increasing the operational safety specific to structures with a free discharge threshold, by reliably allowing the evacuation of exceptional floods by automatic opening (folding of 'at least one element of the increase) without any monitoring or any human intervention or control device. It is also clear that the surge can be manufactured and installed on the weir sill of a dam or other structure for a lower cost than that of previously known valves, and without major modification of the weir sill.
