Construction technology and quality control of new prestressed concrete T beam

Abstract

Prestressed concrete T beam has been widely used in the construction of modern expressways and railway bridges, and its excellent carrying capacity and economic benefits have been unanimously recognized by the engineering community. However, with the increasing of project scale and the improvement of design requirements, how to improve the construction quality and engineering efficiency of prestressed concrete T beam has become the focus of current research. This paper discusses the production process of new prestressed concrete T beam, including the raw material selection, concrete modulation, steel binding, mold selection and production and prestress application, supervises the whole process of quality control, and proposes solutions to the problems in the project. Through the research on the construction technology and quality control of the new prestressed concrete T beam, it provides a set of valuable engineering practice experience for the relevant personnel in the industry, which is helpful to improve the completion quality and efficiency of the project.
