Abstract

U radu je opisano projektno rješenje sanacije mosta Gornja Reka. Počevši od tehničkih karakteristika mosta dobivenih na temelju geodetskog snimanja objekta, preko obavljenog vizualnog pregleda i istražnih radova pa sve do tehničkog rješenja sanacije spomenutog mosta. Ukratko su objašnjeni mehanizmi degradacije armirano-betonskih objekata kako bi čitatelj stekao dojam o mogućoj problematici na konkretnom objektu što je zatim kroz vizualni pregled i istražne radove predočeno na stvarnom primjeru. Kao glavni problem dotrajalosti ovog mosta navodi se nepostojanje hidroizolacije kao niti kolničke ploče što je posljedično dovelo do procurivanja vode kroz most i trošenja materijala. Projektno rješenje prikazuje obnovu mosta po dinamici izvođenja radova praćeno uvjetima kvalitete materijala za sanaciju, programa kontrole i osiguranja kvalitete te troškovnikom.

Abstract (english)

This master thesis describes the project solution for the rehabilitation of the bridge of Gornja Reka. Starting with the technical characteristics of the bridge, which were determined on the basis of the geodetic survey of the structure, through the visual inspections and detailed investigations carried out, to the technical solution for the rehabilitation. At the beginning, the overview of the degradation mechanisms of reinforced concrete structures is briefly explained and then demonstrated on a selected concrete bridge. The project describes the rehabilitation of a concrete arch bridge on a municipal road whose deterioration is mainly caused by water leakage through the asphalt. Indeed, the bridge was built without a waterproofing system. The dynamics of the rehabilitation work are described in detail, followed by the requirements for the quality of the rehabilitation materials, the quality assurance and the cost of the rehabilitation.
