Abstract

1. Гидроаккумулирующая электростанция с подземным расположением нижнего бассейна, содержащая бассейн, расположенный на поверхности земли, водозаборное сооружение, вертикальный напорный водовод, коммуникационную шахту, аэрационную шахту, наклонную шахту выдачи мощности, станционный узел с гидроагрегатами, нижний бассейн с основными камерами и наклонный транспортный туннель, отличающаяся тем, что нижний бассейн дополнительно имеет короткие туннели, соединительные галереи, напорные соединительные водоводы и распределительную камеру, при этом основные камеры нижнего бассейна выполнены в виде спирально расположенных туннелей в плане, а станционный узел с гидроагрегатами размещен в центре спиралей нижнего бассейна, причем гидроагрегаты станционного узла посредством отсасывающих труб и коротких туннелей соединены с распределительной камерой, которая посредством напорных соединительных водоводов, размещенных радиально относительно нее, соединена с основными камерами нижнего бассейна.2. Комбинированный способ проходки нижнего бассейна, включающий проходку основного наклонного транспортного туннеля от поверхности к подземным сооружениям с помощью туннелепроходческого механизированного комплекса и сооружение основных камер нижнего бассейна, отличающийся тем, что параллельно основному наклонному туннелю проходят дополнительный транспортный туннель и затем осуществляют сооружение нижнего бассейна, который является продолжением транспортных туннелей, при этом сооружение нижнего бассейна ведут в два этапа: на первом этапе проходят пилотную выработку открытым туннелепроходческим механизирован�1. Pumped storage power plant with an underground location of the lower basin, containing a basin located on the surface of the earth, a water intake structure, a vertical pressure conduit, a communication shaft, an aeration shaft, an inclined shaft for power delivery, a station unit with hydroelectric units, a lower pool with main chambers and an inclined transport tunnel , characterized in that the lower basin additionally has short tunnels, connecting galleries, pressure connecting water conduits and a distribution chamber, while the main chambers of the lower basin are made in the form of spirally located tunnels in the plan, and the station unit with hydraulic units is located in the center of the spirals of the lower basin, and The hydroelectric units of the station unit are connected by means of suction pipes and short tunnels to the distribution chamber, which is connected to the main chambers of the lower basin by means of pressure connecting conduits located radially relative to it. The combined method of driving the lower basin, including driving the main inclined transport tunnel from the surface to underground structures using a tunnel-boring mechanized complex and the construction of the main chambers of the lower basin, characterized in that an additional transport tunnel passes parallel to the main inclined tunnel and then the construction of the lower basin is carried out, which is the continuation of the transport tunnels, while the construction of the lower basin is carried out in two stages: at the first stage, they are piloted by an open tunnel-boring mechanized

Claims

1. A pumped storage power plant with an underground lower pool, comprising a pool located on the surface of the earth, a water intake structure, a vertical pressure pipe, a communication shaft, an aeration shaft, an inclined power output shaft, a station unit with hydraulic units, a lower pool with main cameras and an inclined transport tunnel characterized in that the lower pool additionally has short tunnels, connecting galleries, pressure connecting conduits and a distribution chamber, In this case, the main chambers of the lower basin are made in the form of spiral tunnels in plan, and the station assembly with hydraulic units is located in the center of the spirals of the lower basin, and the hydraulic units of the station assembly are connected to the distribution chamber by means of suction pipes and short tunnels, which are installed via radial pressure connection ducts relative to it, connected to the main chambers of the lower basin.

2. The combined method of driving the lower pool, including the passage of the main inclined transport tunnel from the surface to the underground structures using a tunneling mechanized complex and the construction of the main chambers of the lower pool, characterized in that an additional transport tunnel runs parallel to the main inclined tunnel and then the lower pool is constructed, which is a continuation of the transport tunnels, while the construction of the lower basin is carried out in two stages: at the first At the second stage, pilot development is carried out by an open tunneling mechanized complex, and at the second stage, they are finalized to the design circuit using the blasting method, and at the same time as the main chambers of the lower basin are drilled, a station assembly with hydraulic units is constructed, which is located in the center of the lower basin spirals.
