Comprehensive construction of a bridge structure
using the incremental launching method
Road S7, Ostróda MS-22
Project parameters:
- Slant angle: 90.0o,
- Span arrangement: Lt = 33.0 m + 5 × 41.0 m + 33.0 m,
- Length of the load-bearing structure: Lcł = 274.34 m,
- Total length: Lc = 288.0 m,
- Total width: Bc = 36.0 m,
- Height of the load-bearing structure: h = 2.70 m,
- Thickness of deck slab: t = 0.20 m to 0.60 m,
- Load-bearing structure: seven-span, continuous, box girder made of prestressed concrete,
- Intermediate supports: columnar pillars, on pile foundations,
- End supports: reinforced concrete abutments, massive, on pile foundations.
Installation technology:
Concreting subsequent segments of the structure at the plants located behind the abutments and incremental launching onto the target supports.
