Project description:
The underpass located on the Bucuresti – Ploiești direction aims to improve the road traffic on the DN1 in the northern area of the capital.
Lower passage width: 14 m
• two traffic lanes on each direction
• two technical sidewalks (one for each path)
Vertical clearance: 5 m
Tehnology:
The underpass consisted of the construction of two parallel alignments of walls made up of 80 cm diameter tangent columns, between which an excavation will be carried out up to the level of the undercrossing red line. These walls act both as retaining walls and supports for the superstructure.
The underpass superstructure is made up of prestressed precast beams with adherent strings (L=17.50 m; h=0.80 m) arranged juxtaposed on the supporting benches made at the top of the walls from tangent columns. Over these beams, the overconcreting slab was poured, by means of which the frame nodes with the walls were also made.
