Definitions
- - falls crossing structures use large quantities of water
- a large-size lock 10 meters of fall, uses more than 21,000 m 3 of water
- the object of the invention is to alleviate these drawbacks, by means of steep crossing structures of a new design, appreciably reducing the production costs and the loss of time caused by conventional works, without using more of water
- the invention thus relates to a structure for crossing a drop in level on a waterway, between an upstream level and a downstream level, constituted by a succession of at least three substantially honzontal reaches, between the upstream and downstream levels, the diversion bays being separated by doors, each of them being movable between an open poistion, in which it does not oppose the passage of water, and a closed position, in which it separates, in a substantially sealed manner, two successive reaches, or even a reach with the upstream and downstream of the structure
- the invention also relates to a structure for crossing a difference in level on a waterway, between an upstream level and a downstream level, this structure being constituted by a succession of at least - 2 - a reach and at least one contiguous lock, the reach and lock being separated by doors, each of them being movable between an open position, in which it does not oppose the passage of water, and a closed position in which it separates, in a substantially sealed manner, two successive reaches, two successive locks, a reach and a lock or even a reach with the upstream or downstream of the structure.
- the lock thus plays the role of several diversion bays in the previous structure, which can be advantageous depending on the topography.
- the structure records in particular a passage time and a reduced use of water compared to a traditional lock.
- the invention also relates to a vertical drop crossing structure according to one of the two preceding embodiments, characterized in that at least one reach is equipped with an leveling system, such as a pump, in line with a singular point such as a bridge too low, a threshold too high or a shallow water.
- an leveling system such as a pump
- the invention also relates to a method for crossing a height difference, between an upstream level and a downstream level, by a navigation device circulating on a waterway which comprises a structure for crossing the height difference according to the invention. .
- This process consists in successively controlling the doors of the crossing structure to allow the levels of two contiguous reaches to equalize, at least one of these doors being in the open position between two doors in the closed position, so as to allow the navigation unit to pass to the right of the open door when the levels in the diversion bays are substantially equal.
- the structure and the method of crossing the difference in height according to the invention allow a navigation device to pass, without stopping in reach, from an upstream level to a downstream level.
- the machine crosses, step by step, a succession of substantially horizontal reaches. The passage to the right of each door in the open position, between two doors in the closed position, is carried out after equalization of the levels.
- the invention also relates to a method for passing singular points, whether they are too low, in particular bridges, or too high, in particular shoals or lock thresholds, over a waterway which comprises a structure for crossing a height difference according to one of the two preceding embodiments, this process consisting in lowering or raising the reach where this singular point is located, either by gravity or pumping, until its level allows convoy- type of crossing the singular point, the level of the same reach then being brought back to the initial level.
- This particular crossing process can be provided independently of the fall crossing structures according to the invention, its advantages being maintained.
- V target speed of mobile navigation devices, in m / s
- D displacement of the standard convoy, in m3
- minimum is understood to mean the shortest length so that a navigation device traveling at a given set speed from reach to reach does not have to slow down.
- the structures according to the invention can be placed on a steep slope, that is to say the value of which is greater than approximately 1%.
- the difference in levels between two successive reaches of the structure is, in this case, preferably between 1 and 10 m.
- the works can also be provided in a tunnel.
- Any structure according to the invention can be placed at an angle on the embankment of a dam or the side of a hill.
- the difference in level crossing structures according to the invention are advantageously provided on a navigation channel comprising vertical walls, over at least part of its length.
- These rectangular section channels also have a greater depth, compared to conventional channels, the walls of which are gently sloping, to the bottom of the channel.
- the width of the channel can thus be reduced, while obtaining greater hydraulic efficiency.
- these channels allow the navigation of machines with large gauge.
- the vertical walls of this channel comprise holding means, in particular made of sheet piles.
- this channel may have the following characteristics, taken in isolation or in any technically possible combination:
- the retaining means can be leveled underwater so as to create a gentle slope in the boat area, for ecological reasons (spawning grounds, passages - 4 - animals), technique (damping of waves when passing boats and / or propagation waves) and safety (ease of getting back on track for humans and wildlife).
- the walls of the channel have a coping, for example smooth, which can also be extended by a waterproof layer, in particular of ferro-cement, extending gently sloping beyond the level of the holding means, for example to make the channel substantially waterproof.
- FIG. 1 represents an exemplary embodiment of a structure for crossing a difference in height according to the invention
- FIG. 2 represents an exemplary embodiment of a vertical drop crossing structure according to the invention, in which the presence of a lock and that of leveling systems in the upper and lower reaches is combined,
- Figure 3 is a cross-sectional view of a navigation channel with vertical walls
- - Figure 4 is a partial cross-sectional view of a particular embodiment of the channel of Figure 3.
- Figure 1 shows schematically a longitudinal profile of a waterway, comprising a work of crossing difference in level, occurring under the fo ⁇ e of a fall.
- the bottom 1 of the chute structure represented in FIG. 1, is constituted by a succession of elongated zones 11 to 15, substantially horizontal and connected to each other by bearings 21 to 24.
- Doors 31 to 36 are provided upstream of the first level 21, at each level 21 to 24 and downstream of the last level 24. These doors thus define a succession of five reaches 41 to 45, substantially horizontal.
- the water in the first reach 41 is at level A or upstream level, corresponding to the upper level of the waterfall when the door 32 is closed and the door 31 open.
- the water from the last reach 45 is at level B, or downstream level, corresponding to the lower level of the chute, when the door 35 is closed and the door 36 open.
- the invention is not limited to the number of diversion bays illustrated in FIG. 1. In general, a fall crossing structure according to the invention will include more than five diversion bays.
- a navigation device crosses the fall crossing structure according to the invention, as illustrated in FIG. 1, as follows:
- the door 32 is then replaced in the closed position, as illustrated in solid lines in FIG. 1.
- the boat 3 circulates, in turn, in the opposite direction between the level B and the level A. This boat started from the level B, and according to successive stages such as those which have just been described, the rising boat 3 is in the reach 43. As soon as the doors 32 and 34 are in the closed position, the door 33 is placed in the open position, as illustrated in solid lines in FIG. 1.
- the descending machine 2 and the rising boat 3 can cross, the fall crossing structure according to the invention allowing navigation in both directions.
- the width of the doors is advantageously chosen so as to allow two navigation devices to cross even at the level of the doors of the crossing structure according to the invention. This then constitutes a two-way navigation channel continuous from reach to reach.
- the doors can be made in any way.
- these doors can be manoeuvrable under load or not.
- each door will be associated with a system of pipes, with an appropriate diameter.
- the doors When the doors are maneuverable under load, they can for example be lifted, pivoted, or even lowered. In all cases, the complete opening time of the doors must correspond to the time taken by the boats to reach the reach, at the set speed.
- the cost of the fall crossing structure according to the invention essentially depends on the cost of the doors separating each reach.
- the structure according to the invention can also allow the crossing of an area where the slope of the ground is greater than about 1%.
- This structure also includes a series of substantially horizontal reaches, separated by maneuverable doors.
- the height of the landings between two successive reaches is generally in this case between 1 and 10 m, and preferably less than 7 m. Depending on the length of the boats, their navigation will be two-way, or alternating one-way as in a traditional work.
- FIG. 2 schematically represents a longitudinal profile of a waterway, comprising a drop-off crossing structure according to one of the versions of the invention. It includes only three reaches (46, 47 & 48), reach 47 being in fact the airlock of a conventional lock, for example a pre-existing lock within the framework of an upgrade to a higher gauge of a waterway .
- the number of diversion bays and locks of this type of structure according to the invention is not limited to that illustrated in FIG. 2.
- a lock airlock replaces at least three reaches of a structure, since it makes it possible to connect fixed levels, which the structure and the process described can only do by using four doors .
- the term lock includes locks with a savings basin.
- Doors 37 to 40 are provided upstream of the first landing, at each end of the lock chamber and downstream of the last landing. They delimit the diversion bays or airlocks 46 to 48 and participate in the control of the levels.
- the obstructions are constituted by the too low bridge 61, located above the reach 48, by the downstream threshold 62 and the raft of the lock 17, too high, and by the upstream threshold 63, too high. These obstructions, if one wishes to fully use the maximum overall dimensions, require recourse to the leveling process described below.
- the other elements of the description are similar to those of FIG. 1.
- a navigation device 7 crosses the structure according to the invention, as illustrated in FIG. 2, from level B to level A, as follows:
- the doors 40 and 39 are placed in the closed position.
- the leveling means 71 are then put into operation (pumping or gravity emptying according to the topography) and the level of the reach 48 drops to level 8, which releases under the bridge 61 the desired air draft for free passage of the standard convoy.
- the machine 7 can thus enter under the bridge 61, which it would have touched if the reach level had remained level B, and cross it.
- the speed of the machine 7 in the reach 48 is in particular a function of the speed of the leveling, of the distance between on the one hand the doors 40 and
- the supply valves of the lock 47 are partially opened, which draw the water at level A, while keeping the door 39 closed.
- the level in the lock rises to level 9, which clears above the raft 17 and the threshold 62 the depth necessary for the passage of the standard convoy.
- the opening of the door 39 can then be carried out thanks to the equalization of the levels between the two reaches 47 and 48 at level 9.
- the machine 7 can thus pass from the reach 48 to the reach 47, without risk of striking the threshold 62.
- the door 39 is closed and the supply valve of the lock is reopened.
- the settlement is carried out as in a normal lock, until the level in the lock reaches level A.
- the door 38 can be opened as soon as the levels between the two reaches 47 and 46 are equalized at level A, but if device 7 came out at this moment, it would hit threshold 63.
- the leveling process avoids this by closing the door 37 at this time, and by putting the leveling means 72 into operation, in order to reach in the airlock 47 and in the reach 46 the level 10, which gives off at above the threshold 63 and the bottom 16 the depth necessary for the passage of the standard convoy. As soon as this level 10 is reached, the operation of the leveling means is stopped. If you want a faster filling of the lock airlock, it may be advantageous to close the door
- the craft 7 can then pass from the reach 47 to the reach 46, without the risk of hitting the threshold 63. This is also the appropriate time for a navigation device heading downstream, from the reach 46 to the airlock 47, crossing the threshold 63. As soon as this threshold crossed by the machine or devices, the door 38 is closed. The rest of the downstream part of the cycle can then begin on its side.
- the navigation device 7 can then pass from the reach 46 to the upstream reach.
- the foregoing description shows that it is possible for navigation equipment traveling in the opposite direction to cross in the structure, except in the airlock of the lock or locks, the vertical movement of a single reach between two closed doors excludes this possibility.
- - 8 For reasons of economy, the use of upgrading means may not be systematic, if the characteristics of the navigation devices which use the structure during a certain cycle do not require it (boats half loaded by example).
- the lengths of two contiguous diversion bays are not equal.
- the volumes of water they contain are therefore not equal either. Consequently, the equalization of the levels will not be done halfway up.
- the length of the diversion bays can vary between several kilometers and a few tens of meters, without conceptually departing from the scope of the invention.
- a slope crossing structure can be used in a tunnel, since its doors do not have to be completely watertight. They can therefore adapt to small variations in width under the effect of the lateral pressures of the arch.
- the structure according to the invention can also be placed at an angle on the embankment of a dam, or on the side of a hill.
- the channel illustrated in FIG. 3 has vertical walls 51 and 52 over at least part of its length, the bottom of the channel being designated by the reference 53.
- the water level in the canal is shown in solid lines, under the reference 54.
- the size of navigation devices that can transit on a channel depends on the maximum sinking authorized by it.
- the channel according to the invention is deeper, and thanks to the vertical walls it keeps a sufficient wet section to guarantee an adequate speed for the navigation devices.
- These vertical walls require holding means. They can be constituted by sheet piles, which are not illustrated in FIG. 3. To ensure effective holding, these sheet piles are, for example, driven into the ground, over about a third of their height, or anchored.
- This channel may include a smooth crown, serving in particular as a support or guide for boats.
- the channel has a depth of about 6 meters.
- FIG. 4 illustrates an alternative embodiment of the channel described with reference to FIG. 3.
- an earth shoulder 55 is provided at the foot of the wall 52.
- a similar shoulder is also provided at the foot of the wall 51. They are advantageously preceded by a riser 58.
- the means for holding the vertical walls 51 and 52 are leveled underwater so as to create an area 56 with a gentle slope in the boat area.
- the leveling of the holding means is carried out above the level -0.6 meters.
- the crowning 57 is therefore permanently underwater, which prevents any corrosion.
- the crowning 57 can be continued by a waterproof layer, beyond the water level 54. This can in particular be provided when the channel must be waterproof.
- the waterproof layer is for example made of ferro-cement and gently sloping.
- this waterproof layer can be continued up to at least the +0.6 meter dimension, counted from the water level 54.
- a channel as illustrated in FIGS. 3 and 4 allows the passage of the largest known boats, at a depth of 3.5 meters, while it offers a reduced bulk. Its hydraulic efficiency is very satisfactory, due to its great depth (Schijf theory).
- this channel will be two-way over its entire logger with vertical walls, two-way excluding doors, or even one-way alternating with crossing stations.
- This particular navigation channel can be provided independently of the fall crossing structures according to the invention, its edges being maintained. It is also possible to make a channel according to the method, which allows the passage of large-gauge boats, characterized in that its width at the water level 54 is, over most of its length, substantially equal to that of the existing anterior channel with a small size (18 to 24 m wide) or medium size (25 to 33 m wide), of which it reuses the right of way, which allows not to modify the landscape.
- the width in question being generally insufficient to allow the crossing of two large-gauge boats (boats whose width exceeds 9.5 m), there are plans from time to time to widen the anterior canal, on a straight line which should not exceed one third of the total length of the canal.
- the free width of the channel according to the process is at least twice the width of the project boat, so that in the event of a boat failure it can be exceeded or crossed at very low speed at any point on the canal. In general, this condition will be available along old gauge waterways without the need to touch riparian properties or the curtains of trees that line towpaths. - 10 -
- the reference signs inserted after the technical characteristics mentioned in the claims, have the sole purpose of facilitating the understanding of the latter and in no way limit their scope.
