Vostochny launch pad that had cavities in its concrete foundation ready for launches
MOSCOW. Oct 19 (Interfax-AVN) - Cavities detected in the concrete foundation of the Vostochny launch pad have been filled, the press service of the Center for Operation of Space Ground-Based Infrastructure (TsENKI) told Interfax on Friday.
"Special solution has been infused into cavities under the launch pad foundation. The condition of the launch pad foundation on the mobile tower's route was reconciled with the engineering documentation. The pad is ready for launches," the press service said.
TsENKI executives visited the Vostochny launch pad and lauded the accomplished works, it said.
"Thanks to the decisions made on the ground, cavities were filled ahead of schedule without breaching the technology," the press service said.
The mobile tower will be transported by rail as planned, it said.
"The high pace of works and the warm weather made it possible to finish the works, which were initially planned for next year," the press service said.
TsENKI detected inferior concrete under the launch pad foundation. Cavities were found under the ferroconcrete foundation of the mobile tower's rail line in the Vostochny Cosmodrome in July 2018 after the foundation of the mobile tower, the control joint between Blocks A and B, wall waterproofing, and leaks on the site of the construction of the Soyuz-2 launch pad were examined.
According to documents published on the public procurement website, TsENKI will spend over 4.5 million rubles on fixing the cavities. The contract for filling cavities under the ferroconcrete foundation of the mobile tower's rail line has been concluded with LLC Adonis based in Blagoveshchensk.
