    2 By allowing the sluice systems on both sides of the aqueduct arrangement to be in communicating connection with each other, the position energy of the filled sluice chamber water volume is used to fill the second emptied sluice chamber to half lift height, and the remaining water volume to the lifting sluice chamber can either be taken from an accumulator volume with sufficient pressure, or simply pumped from the decreasing sluice chamber volume. In this way, you get a hydrodynamically acting efficient system that allows a level crossing between road and canal.
    The invention will be described in the following in connection with a pair of shown exemplary embodiments, where Fig. 1 shows a side view in section of a level crossing according to the invention in a first starting position, Fig. 2 is a view similar to fi g. 1 but in an intermediate position, F ig. 3 is a view similar to fi g. l but in a second starting position »Fig. 4 shows a variant of a level crossing according to fi g. l, now with associated accumulator magazine, Fig. 5 is a view similar to fi g. 2 in an ongoing locking position, and where Fig. 6 is a view similar to fi g. 3, i.e. in the vicinity of a second starting position. 3 The level crossing between canal / watercourse and road / railway according to fi g. 1 has a first lock 1 which is maximally filled and a second lock 2 which is completely emptied, i.e. the lock gates are open to an aqueduct part at the maximum height level at lock 1 and to the height level of the canal / watercourse at lock 2, resp. closed outwards at lock l and inwards at lock 2. The open lock gate between lock l and the aqueduct allows boats to pass in and out. A widening of the aqueduct part makes it possible for there to be boats in both directions during the locking process, ie. when both lock gates delimiting the aqueduct part are closed. The volume of water found in the aqueduct part is in principle constant and changes only in dependent change of the displacement of the boats accommodated in the aqueduct, ie. the water level in the aqueduct part is kept as constant as possible. The length of the aqueduct part corresponds in principle to the width of the road and can preferably accommodate boats traveling in both directions. It then has a width that allows this, ie. meeting between boats in the aqueduct part.
    It should be noted that here only one lock chamber has been shown at each end of the aqueduct part. However, there is nothing to prevent two or two of your lock chambers from being used at one or both ends of the aqueduct section.
    I fi g. 2 thus shows the intermediate position where the lock chambers are emptied resp. filled, which can be done very efficiently until an equilibrium situation has arisen. In order for the volume flow to be as constant as possible, there may be reasons to restrict a free flow at the greatest height differences between the water levels in the two lock chambers, while the closer equilibrium position may require an active pumping effect to have a reasonable time to the equilibrium position and thereafter. an active pumping action is required for the second starting position to be achieved and for the lock gate to enter the canal / watercourse to be opened, resp. the lock gate in the second lock chamber must be able to open to the aqueduct part. This mode is displayed in fi g. 3.
    I f1g. 4 shows a water accumulator reservoir with a volume of at least half the sluice chamber volume and with an overpressure or a spatial location completely above the highest level in a completely filled sluice chamber. It is thus possible to place such an accumulator magazine on an elevation in the surrounding landscape, or to build it into the lock system itself at a higher level. Which alternative is chosen depends on the soil conditions, ie. if it is relatively easy to reinforce the ground for both the lock water volumes, the aqueduct with water volume and the accumulator with water volume.
    Fig. 5 shows a connected turbine function for throttling the water flow between the lock chambers in an initial volume change stage, which turbine can, directly or indirectly, drive a pump to charge the accumulator part.
    I fi g. 6 shows how the volume accommodated in the accumulator part can be used to fill the lock chamber, if necessary, ie. to compensate for water losses.
    It should be noted that the present invention can be used both in canal systems or watercourses with no or little water fate. In the case of watercourses with a larger volume ack fate, accumulator reservoirs with water under pressure can be achieved relatively easily. In excavated canal systems without significant fl fate, the level crossing function can be performed with little water consumption, except that a pumping effect must be applied to drive the transport function of the level crossing for the watercraft.
    The invention is not limited to the embodiments shown above, but the invention can be modified and given other embodiments on the basis of the following stated claims.
