Further, the calculated number of rectangular blocks of the new pipe is set on the side of the installation area of units of the new pipe. Then anchor plates and metal cross-bars are installed from two external sides from installed units of new pipe. Thereafter, blind anchors are formed at the inlet, on the side of the assembly area of units of the new pipe, and at the outlet, after the installed units of the new pipe. Then 2 bundles of 12 strands are drawn through centering holes and clips and collets are fixed on blind anchors, wherein in the area of assembly of blocks of the new pipe, as well as in the area of dismantling of blocks of the old pipe, both bundles of strands are equipped with butt joints.
