Techniques for the Construction of the Cast-in-Place ,Simple-Support, Pre-Stressed Concrete Platform Beam of the Elevated Station of a High-Spccd Railway

With the mega bridge at the Wuwei Railway Station of the Hefei-Fuzhou Railway as a practical example, key tech- niques for the construction of the cast-in-place platform beam of the elevated station of a high-speed railway, such as the erection of the bowl-like supporting system, the pre-compressing of the support, the provision of the pre-camber, the fixing of the bridge pedestals, the fixing of the shuttering and steel bars,the pre-laying and pre-burying operation for the pre-station and post-sta- tion junction projects,the construction of the pre-stressed concrete, etc. ,are introduced in detail in the paper. The quality of the body of the beam is found up to the requirements of design by technical tests. The experience obtained from the construction of this project may be of certain value in guiding the technical management of other similar projects in the future.
