Abstract: | Short-line method of prefabrication and segmental erection of"Simple Supporting before Continuous Joints"are complex,with high construction difficulty and high quality control difficulty,so it is necessary to conduct in-depth study on the key technologies of construction quality control.Taking a viaduct project as the case,this paper studies the construction quality control technology of several key steps,such as survey,concrete pouring,prestressing,segmantal beam gluing and temporary tensioning.The case study has achieved good results in practice and can provide reference for similar projects in the future. |
