Prestressed concrete continuous girder section precast assembling marks the development direction of current bridge building. Precast and assembling can be carried out at the same time and the factorized and mechanized construction quality is guaranteed. The technology has little impact on environment, can shorten construction period and improve con-struction efficiency. Thus, the technology that simply supports first and then precasts and assembles later is applied to the construction of the approach bridge of Taohuau Yellow River Bridge of Wuxi Freeway. The paper introduces the construction and technology, namely, section assembling can be quicken by optimized equipment, splicing material and technique.
