Abstract
Incremental launching erection is a widely construction technology, which has the advantages of low cost, low environmental requirements, simple equipment. In this project, the multi-point support rolling device is used instead of the linear or planar slide support system, and the short nose bridge-fishing method is further used to realize the smooth pier of the beam body. According to the site, a simple and easy deviation correction device is designed. According to the simulation results of deflection calculation and field deflection measurement data, the construction monitoring of the process of incremental launching was carried out, and the incremental launching construction was successfully completed.
