Szczecin: magistrala nie tam, gdzie zakładano. Renowacja potrwa dłużej

Przy modernizacji starych sieci podziemnych rzeczywiste położenie przewodów nie zawsze odpowiada dokumentacji, co wymaga dodatkowych pomiarów i zmian w sposobie prowadzenia robót. Tak jest na ul. Wawrzyniaka w Szczecinie, gdzie nieprzewidziane warunki pod ziemią wydłużyły bezwykopową renowację około 460 m magistrali wodociągowej DN800.

Wodociąg odnawiany jest od wewnątrz. Zastosowano wykładzinę CIPP z tkaniny z włókna szklanego nasączonej żywicą oraz odśrodkowy natrysk kompozytu na bazie żywicy. Według ZWiK Szczecin takie rozwiązanie wykorzystywane jest na wodociągu w mieście po raz pierwszy. Renowacja ma ograniczyć ryzyko awarii.

Przeszkodą okazało się inne niż zakładano usytuowanie magistrali i układu odwodnienia komory zasuw. Wykonawca musiał przeprowadzić dodatkową inwentaryzację i inspekcje oraz dostosować rozwiązania techniczne do zastanych warunków.

Przy komorze stwierdzono także wypłukanie gruntu w sąsiedztwie torowiska. Aby zapewnić bezpieczeństwo jego konstrukcji, konieczna była zmiana sposobu prowadzenia prac. Za realizację zadania odpowiada konsorcjum BLEJKAN S.A. i TERLAN S.A. Wartość robót wynosi 3,483 mln zł netto.
