Strengthening Of Reinforced Concrete Box Structure Design And Construction

Background paper for the Guangdong Guangzhou-Huizhou Expressway project Xiaojinkou Box Interchanges reinforcement.Interchange is located in a small Chrysostom, Huizhou City, Guangdong Province, close to Xiao Jin Town. Chrysostom exchange hub is located in a small and hilly terrain, geological conditions good, loam, sandstone, conglomerate.2 main line viaduct for small Chrysostom exchange hub for one of the main bridge. In order to successfully complete the background of works, through study and research, primarily in technology to address the following points:â‘ Strengthening of reinforced concrete box girder Crack Detectionâ‘¡Strengthening of reinforced concrete box girder structure calculation and analysis of the reasons for crack formationâ‘¢Strengthening of reinforced Concrete Reinforcing Design Boxâ‘£Strengthening of reinforced Concrete Reinforcing Construction BoxLarge quantities of PC box girder after years of use, has been gradually or specification does not permit the cracks began to appear, through this study, we can draw on for such reinforcement Tigong.This comprehensive summary of the Guangdong Guangzhou-Huizhou Expressway Interchanges Box Xiaojinkou Key construction reinforcement techniques, Crack PC box girder construction technology processing role to provide a reference and reference value.The following article is divided into six parts:1, briefly introduced the non-pre-stressed concrete box girder box girder cracks significance of the research, evaluation and reinforcement of existing bridges disease situation, RC box girder concrete crack job description, and explains the purpose and significance of this paper and main tasks.2, on the background of engineering Guangdong Guangzhou-Huizhou Expressway Interchanges Xiaojinkou Status and Inspection of the box have been described, including the project profiles, content and methods of testing, quality test results and evaluation.3, this section focuses on small Chrysostom Guangdong Guangzhou-Huizhou Expressway Interchanges Box ansys solid65 analysis.4, this section focuses on small Chrysostom Guangdong Guangzhou-Huizhou Expressway Interchanges Box Box crack causes.5, this section focuses on the Canton-Canton Freeway Interchanges Xiaojinkou box reinforcement.6, this section focuses on small Chrysostom Guangdong Guangzhou-Huizhou Expressway Interchange Interchange Box Reinforcement Construction.
