On the 25th of July 2013 works on installation of continuous flight auger piles for the Service Zone foundation along the New Safe Confinement northern trench, which is the area of the Arch design position after the skidding, were completed.
The first pile for the Service Zone foundation was installed on April 19 this year. 1,058 cubic meters of concrete was laid and 208 continuous flight auger piles were installed at a depth of 19 meters each during the concrete bedding process. The works were performed under radiation-hazardous conditions of the Shelter Object Local Zone.
The works on assembling of reinforcement cages and laying of concrete for installation of ground beams of the Service Zone foundation at the northern trench are in progress at the moment. As of July 25, 2013, out of the total amount 33.79% of reinforcement bars was assembled and 8.23% of concrete mixture was laid.
The installation of the southern trench foundations are planned to be commenced in September 2013 following the state expert review of the design documentation.
