en.Wedoany.com Reported - Recently, the beam and slab erection work for the Da'an No. 3 Bridge on the Cangtai Expressway Lot 9 project in Zhejiang Province, undertaken by the Corps Construction Company of China's Beixin Road & Bridge Group, was successfully completed, with the final T-beam precisely positioned. This road and bridge milestone provides a foundation for the comprehensive construction of the subsequent bridge deck system and ancillary works.
The Da'an section of this road and bridge project comprises a total of five bridges, numbered 1 through 5. The superstructures all utilize prestressed concrete post-tensioned T-beams, designed with a construction process of simply supported first, then continuous. Following the completion of the erection task for the Da'an No. 3 Bridge, the cumulative total of beams and slabs erected for Da'an Bridges 1 through 5 has reached 312 pieces.
During the advancement of this road and bridge construction, the project team faced multiple construction condition constraints. A 35kV high-voltage power line traverses above the bridge, with strict control standards for safety clearance; below, the bridge needed to span a local township road, involving multiple tasks such as temporary road closures and surrounding traffic management. In response to the complex on-site conditions of this road and bridge, the Cangtai Expressway Lot 9 project department prepared a specialized construction plan, strictly controlling the safety distance between the bridge erecting machine and the high-voltage line throughout the process, and simultaneously implementing bottom protective measures for the beams during the road closure construction period to ensure the safe advancement of beam erection operations under high-risk working conditions.
The project team will continue to advance the subsequent construction of this road and bridge, striving to meet the annual construction targets.
