洛三高速改扩建双拼段新老梁板拼接技术研究

Research and application on the technologies of old and new slab splicing in Luosan Expressway Expansion Semi-detached Section

在交通流量大、重荷载车辆多的情况下,针对双拼段空心板桥及T梁桥的改扩建施工,分别提出了两种施工工艺,以保证交通安全畅通的前提下桥梁拼接施工顺利实施。

In the cases of heavy traffic and enormousvehicleswith heavy load, for the expansion and construction ofHollow Slab Beam and TBridge in semi-detached section, this paper proposed two construction technologies respec-tively to ensure the smooth implementation of the mosaic and bridge construction under safe and smooth traffic.
