The invention relates to the field of hydropower, in particular to the construction of river low-head hydroelectric power plants using the method of their delivery from the factory to the place of their operation, where complete all work to full readiness for exams.
There is a method of towing in the Kola Bay tidal power plant built in the dry dock and using pontoons and tugs delivered in an Acidic lip, which successfully works from 1968 to the present day.
The disadvantage of this method is the impossibility of its implementation for designs, sizes, which at times exceed Kislogubskuyu PES, the use of the dock significantly increases the cost of such construction. The technical result of the invention is that its implementation requires a single berth and complex at the same time carried out on a single work schedule in line with the overlap of the river, such as the strengthening of the coast, structures interfacing counter dams, and products, prefabricated, includes power units installed in the float globular structures with their unique ability to work with little under a stream of any kind, two pairs of double partitioned gate, their willingness must come before the Assembly floating Foundation, because when the tug is VKE they must be inside the walls of the Foundation, and one pair in the cargo compartment gateway protected flooring, temporarily used as pontoons as when building the raft Foundation and build up the sides (walls) float hydroelectric (SGPP). The common ground consists of two compartments: engine compartment (MO) and navigation airlock compartment (SHO), - collect the berth of the pipes, steel or special W/b, the diameter of which provides sufficient buoyancy to support the load in the form of racks to build walls and tubular supports for mounting the gate. Weld the pipe on the pontoons in separate blocks, to build the framework of the Foundation they need 5, two longitudinal and three transverse, with two belonging to SHAW, the weld ribs being samouglubleniyu under the weight of the structure, they will prevent possible erosion due to the difference of the difference of levels inside SHO.
This technical result is achieved in that the assembled Foundation with the help of tugs bring overlap a channel that already has a concrete stops, provides a stop of the Foundation at a given point, one of the stops connected with interfacing dam, which laid the siphons for interfacing them with weirs float of units in the design of the Foundation. Complete work on the building sides (walls) on the Foundation, and the uses standardized ready slabs of reinforced concrete, setting them W/W of the rack, and at the same time while building the walls of the shipping gateway, strengthen them outside alluvial soil, then set both pairs of double shut-off gate, leaving them open before you put the culverts and block closure channel located between the wall of the gateway module and interfacing dam opposite Bank of the river.
When you install the units and connect them to the spillways and outlet and overlapping the gate line, float power, combined with the shipping gateway, and commissioned. When excess energy resource of the river there is an opportunity to connect in addition to the previously installed culverts pavanelli working in horizontal turbines.
In figure 1, the plan shows a diagram of the float hydroelectric, combined with shipping gateway, and 8 of the float units, 4 of them installed in the vertical position of the turbines, the other connected to the culverts that are in mating dams. The viaduct over the gateway is not shown, it may be in the form of a drawbridge.
Figure 2 schematically shows the float unit in the section.
1 - camera fill hydroblaster for turbine installation in the horizontal position,
2 - chamber for the reception of ballast vertical turbine operation.
Summary of the invention for luchetta is the Foundation for the total building where is located the engine and shipping gateway, gather at the pier of the port or factory of steel or reinforced concrete pipes of large diameter, with sufficient buoyancy to together with pontoons to deliver the basement to the ground floor river target, and with it the necessary frame construction. The construction of hydroelectric power plants with a combined shipping gateways allows you to save expensive materials in the form of steel sheet piles and piles, as if floating the method of construction eliminates the need for costly paranah. In this way need only two pile stops to keep being afloat Foundation, to which both sides by reclamation erect interfacing of the dam body, which lay along the siphons, his discharge is able to provide operation of the float units. The value of the units that they are in working condition as soon as they will attach to the jet stream. The versatility of the units in the fact that a turbine with a generator located in the spherical case, in which there are two chambers for receiving water ballast. The cameras are positioned so that, filling one chamber, the turbine is connected to the work in a vertical position, freeing about the ballast first and filling them a second, turbine is in a horizontal position, the most productive because of parametreleri. In the construction of walls on the Foundation he flooded outside the walls of the airlock compartment strengthened alluvial soil. Float hydropower and navigation gateway are in working condition after will be closed both pairs of the gate and has at least one unit. Overpass, bridge, paving over the gateway of the camera.
