预应力混凝土梁预制在桥梁结构中,广泛使用预应力混凝土梁。提高技术人员的技术水平、加强现场管理是提高预应力混凝土梁质量的重要手段。预应力混凝土梁的预制施工包含预制场地的选择和建设,模板设计、制造和安装,钢筋绑扎,预应力体系的安装,预埋件的正确埋设,混凝土的拌制、输送和浇注,混凝土的养护,预应力孔道的压
Prestressed concrete beams prefabricated in the bridge structure, the widespread use of prestressed concrete beams. Improve the technical level of technical personnel, strengthen site management is an important means to improve the quality of prestressed concrete beams. Prefabrication of prestressed concrete beams involves the selection and construction of prefabricated sites, the design, manufacture and installation of modules, the binding of reinforcing bars, the installation of prestressed systems, the correct embedding of embedded parts, the concrete mixing, conveying and pouring, the curing of concrete , Prestressed pore pressure
