摘要
苏通大桥主引桥为双幅6车道75 m跨等截面PC连续梁桥,其上部结构采用预制节段拼装架设的施工方法。介绍TP75节段拼装架桥机在该工程中的设计方案、主要部件及施工步骤。
The main parts of the approach bridges of Sutong Bridge are of twin prestressed concrete continuous girder bridges with spans each 75 m of constant cross sections and six lanes on the carriageways, and the superstructures of the parts of the bridges were erected by precast segmental assembling construction method. In this paper, the design alternatives, principal components and construction sequences of the TP75 overhead launching gantry used for the segmental assembling of the bridges are described.
