Director of the Dnieper Hydroelectric Power Station Viktor Kucher said that the issue of reconstruction of the hydroelectric power station is very important and requires an early solution. The DniproHES dam has been in operation for more than 89 years, it has experienced destruction and restoration twice in its history, and today the state of the structure is assessed by specialists as of limited working capacity.
Very important for Ukrhydroenergo and the city of Zaporozhye, the issue of reconstruction of the road crossing through the DneproGES dam was discussed at the next meeting of the Scientific and Technical Council. The meeting was attended by the first deputy mayor for the activities of the executive bodies of the council of the city of Zaporozhye Alexander Vlasyuk and the deputy mayor for the activities of the executive bodies of the council of the city of Zaporozhye Alexander Konstantinov, the chairman and deputy chairman of the district administration for the Dnieper region.
The considered variant of the conceptual solution provides for a two-level auto-crossing over the dam of the hydroelectric power station with wide pedestrian and bicycle paths. The chief engineer of the project, Vadim Galat, presented the first stage of the project development on the basis of conceptual solutions developed and previously approved by the scientific and technical council for the development of the reconstruction of the road crossing.
“An important element that has been added to the project is the supports of the bridge across the front chambers, since during the post-war period these supports were not subject to detailed examination and restoration. Together with the designers, we came to the understanding that these structures require a very detailed survey and strengthening, "- said Vadim Galat.
Vadim Galat also noted that before the construction of the bridge, a large-scale survey will be carried out, including the underwater parts of the dam.
The Scientific and Technical Council approved the project developed by the Ukrgidproject for the reconstruction of a bridge crossing over the dam of the Dnieper hydroelectric power station as part of a single-tier flyover through locks, sections of the interface with the left bank of metal spans on reinforced concrete supports, a two-tiered reinforced concrete bridge across the dam with a metal bridge through a variable-section anterior chamber, connecting the two-tiered structure of the bridge over the dam and the road on the right bank. Reinforcement of all pillars of the bridge across the forecourt with a reinforced concrete bandage and reinforcement of the dams in accordance with the design requirements will also be carried out, and the reconstruction of the surfaces of the bulls and the weir surfaces of the dam will be carried out.
