随着我国公路桥梁事业的发展桥梁科研水平的提高桥梁技术体系不断丰富有钢架桥悬索桥拱式体系梁式体系桥梁等等。其中梁式体系在大中型桥梁中占有一席之地而预应力砼箱梁的预制质量优劣关系着后续工序诸如体系转换等环节的成败。又预应力混凝土箱梁施工生产过程中梁体产生各种裂纹箱梁裂纹影响梁体整体质量给以后使用埋下重大隐患现结合作者本人所在项目部的一座预应力混凝土连续箱梁大桥来谈谈箱梁预制时出现裂纹采取的一些质量控制措施。以供同行参考!
With the development of road and bridge in our country, the research level of bridges has been improved. The bridge technology system has been enriched continuously with arch bridge beam system bridges of steel suspension bridge and so on. Among them, the beam system occupies a place in large and medium-sized bridges and the quality of the prefabricated concrete box girder is related to the success or failure of subsequent processes such as system conversion. And prestressed concrete box girder during the production process of producing a variety of cracks in the box girder crack affect the overall quality of the beam to the future use of buried under a major hidden danger Now I am in the project department of a prestressed concrete box girder bridge to talk about Some quality control measures taken when cracks occur in box girder prefabrication.
