随着城市建设的发展,不断涌现处各种新技术、新工艺。由于预应力混凝土连续箱梁具有结构整体性好、跨径大,能有效减少桥面伸缩缝的数量,使得行车环境变的更加舒适而得到广泛应用。以此为出发点,本文结合工程实例,分析了预应力混凝土连续箱梁预制施工中底模、钢筋、模板、波纹管、预埋件等方面的质量控制要点,提出了施工改进措施,旨在提高预制质量。 With the development of urban construction, a variety of new technologies and new processes are emerging. As the prestressed concrete continuous box girder with good structural integrity, large span, can effectively reduce the number of bridge expansion joints, making the driving environment becomes more comfortable and widely used. Taking this as a starting point, this paper analyzes the key points of quality control of bottom mold, steel bar, template, corrugated pipe, embedded parts and so on in the precast construction of prestressed concrete continuous box girder by combining with the engineering examples. The improvement measures of construction are put forward to improve Prefabricated quality.
