The rigid portal systems.

The rigid portal systems are prefabricated units made of reinforced concrete and serve as bedding for the longitudinal bearer units. Dimensioned and reinforced in accordance with the checked structural-analysis data, they are placed on the deep foundations and thus connected. The rigid portal systems, in turn, serve as bedding for the longitudinal bearer units (LTEs).

The rigid portal systems installed in the test section have a length of 1.5 m, a width of 3.0 m and a height of 0.5 m.
