The gateway to the savings pool 5 is as follows.

With the lower gate 3 closed and the upper gate 2 closed, the vessel is entered into the main measure 1. The water level in the filled chamber 1 corresponds to the water level in the upstream 13. At this point, the water displacing element 7 is in the upper part of the savings pool 6 and auxiliary. 1, chamber 14 is filled with water to the level of the upper pool 13, and the gate of the semi-gateway 15 is open. A vessel whose dimensions correspond to the dimensions of chamber 14 or several small size vessels of the main chamber 1 is entered into the auxiliary chamber 14 from the upper bay 13 after the channel 16. After entering the vessels into the main 1 and auxiliary 14 chambers, the upper gate 2 and the gate opener 15 are closed and The main chamber 1 is emptied. For this purpose, the water-displacing element 7 moves along the savings pool 6, lowering its curviline bottom 8 from the top point 12 to the bottom point 17 towards the downstream 20. Releasing in front of the water-displacing element 7, the volume is filled by the water-flow flowing here 5

Two of the main chamber with water 4, and lowering the water level in the main chamber corresponds to lowering element 7 along the bottom 8 when moving along the savings pool 6 and lowering the water level in the basin 6 itself. This allows you to save water depth before element 7, and therefore, it is possible to unload the actuator 9 by means of the cable block system I1 by the counterweight 10. The counterweight 10 can be implemented as platforms with a load on a track or a load moving in a vertical bashna (not shown). It is intended to be accumulated — converting the potential energy of water as the water level decreases when snapping into the potential energy of the raised counterweights 10.

The vessel in the main chamber 1 is lowered vertically during its emptying, as in

The research institute pool 13 is carried out in reverse order, with the accumulated energy of the raised counterweights 10 being expended to raise the level in chambers 1 and 14 by displacing element 7 out of the savings pool 6. If necessary, the gateway can work as usual savings pool b overlap of the conduit 4 gate 5.

Emptying with an auxiliary with the lower pool, in the displacing chamber 14 occurs at a decrease in the output from the savings pool of the element level in basin 6 by an amount T, after which the navigable hole is made, with After that, water in pool 6 is supplied only to 25 e.m. The parameter a is determined for the area to from the main chamber 1. This occurs when element 7 is located at point 22 of bottom 8 of basin 6. Water depth T in sub-chamber 14 is assigned not only based on the conditions for safe entry of the vessel into it from the headwater 13, but also from the condition of safe withdrawal of the vessel from sub-chamber 14 while along the savings pool 6 while simultaneously lowering the water level in chamber 14 and basin 6. As element 7 displaces water, moves along savings bank 6 along its curvilinear bottom 8, described by a special dependence, from the midpoint 22 the lower point 17, the final emptying of the main chamber 1 occurs.
