三川河7号特大桥预应力T梁预制施工工艺

Construction technology for prefabrication of prestressed T-beam in No.7 super large bridge of Sanchuan river

结合三川河7号特大桥预应力T梁施工实践,从T梁钢筋施工和T梁混凝土施工两方面介绍了40 m预应力T梁预制的具体施工工艺,为其他类似桥梁施工提供了参考。

Combined with practice in prestressed T-beam construction of No. 7 super large bridge of Sanchuan fiver, from reinforcement work and concrete construction of T-beam the construction technology for prefabrication of 40 m prestressed T-beam is introduced, which provide good references for the construction of similar works of bridge.
