- Abstract
Based on the construction of the Heishui River Bridge during the reconstruction of National Highway G353 in Ningnan County, a supporting project of Baihetan Hydropower Station, the paper presents the research on the bridge construction technology to convert land-based construction to over-water construction of piers for the continuous rigid frame bridge located in a mountainous reservoir. After comparison of pontoon bridges with cable cranes and catwalks, the "pontoon bridge" proposal was selected and accepted, with the pontoon bridge made up of fabricated polythelene pontoons together with a floating platform, a transfer construction elevator and tower cranes. The results show that the "pontoon bridge" proposal had advantages in construction under such special working conditions, and may provide reference for similar projects.
