T构桥0号块预埋件多，管道密集，结构受力复杂，是桥梁施工的关键部位。结合大桥乡大桥0号块施工实践，重点介绍了托架与模板设计、预应力箱的张拉与孔道灌浆技术。对普通钢筋的施工及混凝土灌注也作了较详细的阐述。

The start elements of Tshaped girder bridges, which have numerous embedded parts, concentrated pipes and complex structural stress, are critical parts of bridge construction. On basis of the construction of the start elements of Daqiaoxiang bridge, the author presents the design of the brackets and formworks, the tensioning of the prestressed boxes, the duct grouting technology, the construction of ordinary rebars and concrete casting.
