Project description:
The subject of the work was the delivery and installation of an additional prestressing system with a weight of prestressing reinforcement of 22.2 tons. The bridge structure C203 brings Hradecká street in the direction from the centre to Svitavy over the Královopolská street. The bridge structure C204 brings Hradecká street over Královopolská Street in the direction from Svitavy. The load-bearing structure is designed as a three-span beam, straight. The span of the individual fields is 22.5 + 32.0 + 22.5 m. In the transverse direction, the load-bearing structure has the shape of a two-chamber beam. The supporting structure was prestressed by longitudinally lifted cables 12o Ls15.7 - 1860 Mpa. The upper slab was prestressed with longitudinal cables 7o Ls15.7 - 1860 Mpa. The end crossmembers were transversely prestressed with 7o Ls15.7 - 1860 MPa cables. The cables were stored in steel protectors type LW 80 mm and 65 mm. After prestressing the structure, the cable ducts were grouted with cement mortar.
