Definitions
- the present invention relates to an automatic rise for a hydraulic structure such as a river threshold, weir over a dam or a protective dike, of the type comprising a structure forming a watertight or substantially watertight wall, installed on said hydraulic structure.
- Automatic hikes of this type are well known.
- automatic rises are installed for example on the crest of a threshold arranged across a river in order to raise the water level of the river upstream of the threshold. They can also be installed on the threshold.
- a weir of a dam in order to raise the level of the reservoir (reservoir) of the dam. They can still be installed on the threshold of the weir of a dyke bordering a river and intended to protect the regions neighboring against the flooding of the river, the weir being, in the latter case, installed on the dyke at a location which is chosen so that, in the event of a flood, the water flows into a storage tank or onto a chosen land, safe for other regions bordering the river.
- Automatic rises can be of the non-spill type or of the spill type, that is, in the second case, they can allow a certain amount of water to pass over their crest as long as the level of the water upstream of the rise does not exceed a predetermined height.
- the automatic rises must be able to be erased automatically if the water level upstream of the rise reaches a predetermined level during a flood, in order to release the mass of water which it retains and thus avoid flooding of the regions surrounding the river or, if necessary, damage to the dam or dam.
- FIG. 1 of the accompanying drawings shows schematically, in side elevation, a known automatic rise of the type defined above, which can be considered to represent the state of the art closest to the present invention.
- a model of this known automatic rise was exhibited at the time of the International Congress of Large Dams which was held in DURBAN, in the Republic of South Africa, in November 1994.
- the known automatic rise represented in figure 1 is essentially constituted by a plate 1, vertical or oblique, which, at its base, is articulated on the crest 2 of the threshold or weir 3 in masonry by means of a hinge 4 or other similar element.
- the plate 1 is retained in the upright position shown in solid lines in FIG.
- the fastener 6 comprises two parts 6a and 6b, which are respectively fixed to the masonry of the threshold or the weir 3 and to the tie rod 5, and a dowel 6c, which is threaded in aligned holes drilled in the parts 6a and 6b and which couples these two parts to each other .
- the body of water 7 which is retained by the plate 1 exerts a thrust thereon.
- tie rod (s) 5 are under tension and, as a result, that the pin 6c of the fastener 6 is subjected to a shearing force.
- the value of this shear force is proportional to the value of the tension of the tie rod 5, which is itself proportional to the value of the thrust exerted by the body of water 7 on the plate 1.
- the value of this thrust is itself an increasing function of the level of the body of water 7, that is to say of the height of water above the crest 2 of the threshold or of the weir 3.
- pin 6c breaks and, under the pressure of the water, plate 1 automatically collapses on the ridge 2 of the threshold or weir 3 by pivoting around the axis of the hinge 4 as far as the position shown in dashed lines in FIG. 1.
- the diameter and / or the material (generally steel) of the dowel 6c so that it has an appropriate shear strength, it is possible to make out e that the pin 6c of the fastener 6 breaks for a predefined water load, therefore when the water level upstream of the plate 1 reaches a predefined level.
- the lock (s) must be actuated by an operator to detach the panel (s) and release the mass of water they retain, so that this rise does not work automatically.
- One could easily conceive of an automation of the operation of this rise by replacing the movable element of the lock by a shearable pin similar to that described in connection with the known automatic rise described with reference to Figures 1 and 2 of the accompanying drawings.
- the increase would still suffer from the same defect as the known increase previously described in this which concerns the precision of the water level at which the rupture of the shearable anchor occurs.
- the present invention therefore aims to provide an automatic rise of the type defined in the preamble, which operates with better precision than the known automatic increases of the same type, with regard to the water level which causes the triggering of the rise.
- the rise according to the present invention is characterized in that it further comprises a massive element which is movably mounted on said structure and coupled to said body of water so as to be in a stable equilibrium position as long as the water remains below a predetermined level, and to pass into an unstable state and to be moved when the water reaches said predetermined level, and in that the connection between said elongate retaining element and the reaction point is eliminated by the displacement of said solid element.
- said solid element can be constituted by a slab installed on said work so as to be able to tilt upwards around a horizontal axis which extends along a first side of the slab and which is perpendicular to the direction of the thrust exerted by the body of water on the movable wall forming the rise.
- the solid element can be mounted so as to be able to slide vertically in a cavity open upwards formed in said structure.
- the elongate retaining element may be constituted either by a tie rod or by a strut. In both cases, the connection between the tie rod or the strut and the reaction point can be eliminated in response to the rocking or sliding movement of the solid element.

- the riser 10 is installed at the top of the masonry 11 of a hydraulic structure which is only partially shown in Figure 3 and which can be for example a river threshold or a weir of a dam or a flood protection dike.
- the riser 10 comprises, in known manner, at least one panel 12 which, in normal service, is vertical or slightly inclined relative to the vertical and which is mounted so as to be able to tilt or pivot around a horizontal, virtual or real, which extends parallel to the lower edge of the panel 12, near said lower edge.
- the panel 12 may for example be constituted by a metal plate, a reinforced or unreinforced concrete plate, a composite structure such as a metal frame in which cofferdams are embedded or fixed, or any other structure forming a sealed or substantially wall waterproof.
- the panel 12 or each panel 12 is retained in its vertical or substantially vertical position by at least one tie rod 13, for example two tie rods 13 as shown in FIG. 6.
- Each tie rod 13 can be constituted for example by a metal rod, a cable or a chain.
- One end of each tie 13 is connected to the panel 12 in the upper region thereof, at 14, while the other end of each tie 13 is attached to the masonry 11 by a detachable connection 15 which will be described further several embodiments.
- the rise 10 further comprises a massive element 16, produced here in the form a rectangular slab ( Figure 6) which can be for example concrete, reinforced or not, metal or synthetic material, reinforced or not.
- the slab 16 is placed horizontally on the masonry 11 of the threshold or of the weir and it can tilt upwards around a horizontal axis A which extends along its rib 16a.
- a stop 17 having, for example, seen in cross section, a trapezoidal shape.
- the stop 17 can extend over the entire length of the side 16a of the slab 16 or be made in the form of separate studs as shown in Figure 6, Under these conditions, the tilt axis A of the slab 16 is coincident with the lower edge on its side 16a.
- the abutment (s) 17 are made of masonry and then form an integral part of the masonry 11 of the threshold or of the weir, or they can be constituted by metal parts anchored in an appropriate manner to the masonry 11.
- the or the stops 17 can be replaced by hinges.
- the use of one or more stops 17, in particular in masonry offers the advantage that they are less prone to corrosion than metal hinges.
- the slab 16 has, in its upper surface, near its side 16a, a groove 18 which extends parallel to said side 16a and which has a width greater than the thickness of the lower edge of the panel 12.
- the lower edge of the panel 12 is engaged in the groove 18 and bears against the side 18a of the groove 18 which is closest to the side 16a of the slab 16, as is better visible in FIG. 4, thus, under certain conditions, as as will be seen later, the panel 12 can tilt down around the upper edge B on the side 18a of the groove 18.
- the panel 12 can be connected to the slab 16 by a hinge 19 as shown in FIG.
- the panel 12 can be mounted tilting or pivoting with respect to the masonry 11, for example, the groove 18 can be formed in the masonry 11 downstream of the stop 17 as shown in FIG. 5a or the hinge 19 or other equivalent means can be fixed to the masonry 11 as shown in FIG. 5b, also downstream of the stop 17.
- a seal is placed between the panel 12 and the slab 16 or the masonry there.
- the seal can be installed in the bottom of the groove 18 or, as shown in FIGS. 3 to 5, it may consist of a strip 21, of rubber or other elastomeric material, which is fixed by a flange 22 to the lover face of the panel 12 and extends downward to the upper surface of the slab 16 by covering groove 18 or hinge
- Another seal may also be provided between the slab 16 and the masonry 11, in the region of the side 16b of the slab 16 opposite the side 16a.
- a first embodiment of the detachable link 15 will now be described.
- the lower end of the tie rod 13 is attached to a fixing part 23, which is engaged and retained in a slot 24 arranged between the slab. 16 and the masonry 11.
- the slot 24 extends roughly horizontally under the slab 16 from its side 16b to its side 16a.
- the fixing piece 23 is here constituted by a metal plate with an elongated rectangular cross section, which, when it is engaged in the slot 24, comprises a part which protrudes beyond the side 16b of the slab 16 and to which is attached the lower end of the tie rod 13, As shown in Figure 6, the two tie rods 13 extend parallel to one another and are all two attached to the plate 23 which has a length equal to or slightly shorter than the length of the rib 16b of the slab 16. However, as indicated in phantom in Figure 6, the two tie rods 13 can converge towards the other and be attached to the same point of the plate 23, located in the middle of the length of the side 16b of the slab 16. In the latter case, the plate 23 may have a length significantly shorter than that shown in the figure 6.
- the body of water 25 retained by the panel 12 exerts on it a thrust Pi, the value of which is an increasing function of the height h. water above the crest of the masonry 11.
- This thrust Pi tends to tilt the panel 12 downward around the edge B (FIG. 4 or 5a) or around the axis of articulation of the hinge 19 ( Figure 5 or 5b).
- each of the two tie rods 13 is energized and the tension T of each tie rod is an increasing function of the thrust PT, therefore of the height h water, The tension T of each tie rod is transmitted to the plate 23 which, therefore, tends to tilt upwards around its edge C ( see also FIG. 10).
- the plate 23 applies to the panel 16 a force F which is directed upwards and whose intensity is an increasing function of the voltage T.
- the intensity of the force F also depends on the cosine of the angle between the direction of the tension T and the vertical direction, and the ratio between the distances l ⁇ to 1 2 for application of the forces T and point F, respectively, with respect to the edge C (see Figure 10).
- the slab lô tends to tilt upwards around the axis A formed by the lower edge of its side 16a.
- the slab 16 is subjected to its own weight P ⁇ , to the weight Pa of the mass of water located above it and to a force P * which is the result of the thrust Pi and the weight proper of the panel 12. It will be noted that the influence of this last force P * on the balance of the slab 16 can be canceled or made negligible if, by construction, the direction of the force P 4 intersects the axis A or passes very close to it. In the case of FIGS. 5a and 5b, the force P * is not to be taken into consideration since the panel 12 is supported by the masonry 11 and does not exert any direct action on the slab 16. As long as the moment of the force F with respect to the axis
- the slab 16 remains in its equilibrium position shown in FIG. 3.
- the tension T of the tie rods 13 increases and, consequently, the force F also increases as does the weight Pa of the body of water 25 above the slab 16,
- the moment of the force F with respect to the axis A increases faster than the antagonistic moment of the weight Ps with respect to the axis A.
- the moment of the force F relative to the axis A reached and exceeds the sum of the moments of the forces P 2 , Ps and possibly F ⁇ relative to l axis A.
- the slab 16 is unbalanced and begins to tilt up around the axis A.
- the slot 24 widens and the water penetrates under the slab 16 and exerts on the face lower of this pressure directed upwards, which quickly tends to balance the weight P 3 of the water on the slab 16, thus promoting the tilting of the latter around the axis A.
- the slot 24 widens further (see Figure 8) and, after the slab 16 has tilted a few degrees upwards, the plate 23 is released (see Figure 9).
- the panel 12 is no longer retained by the tie rods 13 and, under the thrust Pi of the body of water 25, it rocks around the edge B of the groove 18 (FIG. 4 or 5a) or around of the hinge pin 19 ( Figure 5 or 5b). Consequently, the panel 12 collapses on the masonry 11 and releases the mass of water 25.
- the slab 16 is no longer subjected to the action of the force F, it falls back under the effect of its own weight P 2 and resumes its equilibrium position as shown in FIG. 9,
- said panel can be connected by at least one short flexible link 26, such as a cable or a chain, to a ring 27 anchored to the masonry 11, as shown in Figures 3 and 5a.
- link (s) 26 it is also possible to provide at least one element 28 forming a hook, which is fixed to the downstream face of the panel 12, near the lower edge of the latter, and which cooperates with an additional element retaining 29 rigidly fixed to the slab 16, as shown in Figure 4.
- the water level N for which the automatic rise is triggered can be adjusted by modifying the weight of the slab 16.
- a ballast 31 can be fixed to the slab 16 ( Figure 3).
- the IT level can be adjusted either by modifying the weight value of the ballast 31, or by modifying the position of the ballast 31 on the slab 16, in particular its distance from the tilt axis A.
- conduit 32 (FIGS. 3 or 3a) of which a first end 32a opens out under the slab 16, while its second end 32b opens on the upstream side of the panel 12 at a level corresponding to the predetermined level N.
- the conduit 32 can extend in part in the masonry as shown in Figure 3, or it can be fixed vertically on the slab 16 as shown in Figure 3a.
- the slab 16 and the conduit 32 can also be made in one piece by pouring concrete into a suitable formwork. In the case of FIG.
- the aforementioned weight P2 is the total weight of the slab 16 and of the conduit 32, the latter may for example have a circular cross section ( FIGS. 3 and 6) or an oval cross section or elongated with a hydrodynamic profile such as that shown in phantom in 32c in FIG. 3a.
- the upper end 32b of the conduit 32 will open at a slightly lower level, for example a few centimeters, than the predetermined level N in order to obtain a flow of water sufficient to quickly fill the conduit 32 when the water reaches level N,
- a vertical thrust P s directed upwards, is applied to the slab 16. This thrust P s is established in a relatively short period of time, adds to the force F and quickly causes the tilting of the slab 16 upwards around the axis A.
- the underside of the slab 16 ( Figure 4) or the part of the masonry 11 which is located under the slab 16 ( Figure 3), or both at the same time ( Figure 10) are hollowed out so as to define a chamber 33 into which the end 32a of the duct 32 opens.
- another duct or channel 34 is provided in the masonry 11 (FIG. 3) or in the lower surface of the slab 16 (FIG. 4) to drain towards the 'downstream the water which is possibly in the chamber 33 and whose presence may be due to a defect in the sealing of the aforementioned seals or else to waves which can cause the pipe 32 to fill before the level mean water reaches the predetermined level N.
- the duct 34 has a smaller passage section than that of conduit 32 so that the flow in the duct 34 is weaker than in the duct 32 and that the chamber 33 can be quickly filled with water when the water level has actually reached the predetermined level F.
- the automatic rise 10 described above can be a pouring or non-pouring rise depending on whether the height of the panel 12 is chosen such that its upper edge is at a level lower or higher than the predetermined level N, respectively,
- the panel 12 does not necessarily have an essentially planar shape like that shown in FIGS. 3 and 6, but it can have, when viewed in horizontal section, a non-linear profile, for example a profile crenellated like that of panel 12 ′ as shown in FIG. 7.
- this makes it possible to increase the length of the crest of the panel, therefore to increase the flow rate of the sheet of water which pours over the crest of the panel for a given water level.
- a certain body of water may be present on the downstream side of the panel 12, with a level below the water level of the upstream side of the panel 12, in this case, the body of water downstream of the panel 12 can exert on the downstream face thereof a thrust which partially counterbalances the thrust PT of the water on the upstream face of the panel 12.
- the thrust exerted on the downstream face of the panel 12 has the effect of reducing the value of the tension T of the tie rods 13, therefore also to reduce the value of the force F which tends to tilt the slab 16 upwards. In this case, this thrust should therefore be taken into account for the calculation of the tension T and the force F.
- FIG. 10 illustrates an alternative embodiment of the detachable link 15.
- each tie rod 13 is constituted at least in part by a flexible element such as cable or chain, and passes around a deflection element 35, which is fixed on the slab 16 in the region of its side 16b, so that the end portion of the tie rod 13 which is attached to the plate 23 extends approximately vertically.

- the side 16b of the slab 16 is made in the form of a rounded edge.
- each tie 13 is constituted, at least in part, by a flexible element such as cable or chain, which passes around the rounded edge 16b of the slab 16.

- the fixing piece 23' may for example be constituted by a cylindrical bar having a diameter larger than the width of the horizontal branch of the slot 24, but smaller than the width of the vertical branch of said slot.
- the detachable link 15 shown in Figure 11 operates as follows. As in the previous embodiments, the tie rods 13, which are under tension, tend to tilt the slab 16 around the axis A ( Figure 3).
- the slab 16 rocks upwards, and as soon as the width of the horizontal branch of the slot 24 becomes greater than the diameter of the round section of the bar 23 ', this bar is extracted of the slot 24 under the effect of the tension of the tie rod 13, so that the panel 12 is no longer retained and can collapse under the thrust Pi of the water.

- the tie rod (s) 13 exert on the upper end of the lever (s) 23 "a pull which tends to rotate the said lever (s) 23" in an anticlockwise direction around the point of support constituted by the cylindrical bar 37, and which maintains the lower end of the lever (s) 23 “against the respective stopper (s) 41. It follows that the lever (s) 23" apply to the support point 37, therefore to the slab 16, a force F which tends to tilt it around the axis A ( Figure 3).

- the massive element whose movement causes the triggering of the rise when the water level upstream of the panel 12 reaches the predetermined level ÎT can for example be constituted by a block 16 similar to that described in propo.s of figure 17, but without notch 24 '.
- the block 16 ′ is moved only by the thrust Ps of the water which enters the chamber 33 through the conduit 32 when the water level reaches the predetermined level K.
- a retaining element similar to element 53 of FIG. 17 may be necessary to limit the displacement of the block 16 ′ upwards.
- the upper end of the tie rod 13 is indirectly connected to the panel 12 by a first arm 55 of a pair of articulated arms 55 and 56.
- the second arm 56 of said pair of arms is supported directly or indirectly on the masonry 11 at 57.
- the solid element 16 is constituted by a slab similar to that shown in FIG. 3 and the second arm 56 is supported on a stop 58 formed on slab 16 near its side
- the stop 58 could be formed on the masonry 11.
- the first arm 55 is articulated, at 14, on the downstream face of the panel 12.
- a stop 17 for the slab 16 is provided on the masonry 11.
- the lower end of the tie rod 13 is connected to the masonry 11 by a detachable link 15 similar to that described in connection with Figure 3.
- the detachable link 15 shown in Figure 19 could be replaced by any of the links shown in Figures 10 to 17.
- the slab 16 can be replaced by a sliding block 16 'like that in Figure 17.
- the panel 12, the tie rod 13 and the detachable link 15 constitute a mechanical coupling system between the slab 16 or the block 16 ′ and the body of water 25, while the conduit 32 constitutes a hydraulic coupling system between the slab 16 or the block 16 'and the body of water 25.
- the detachable link 15 or 15' is removed in response to the movement of the slab 16 or of the block 16 'either under the effect of the mechanical coupling system alone, either under the effect of the hydraulic coupling system alone or even under the effect of the two coupling systems at the same time according to the embodiments described.
