“河南第一高桥”逢石河特大桥是河南省高速公路上最大的连续刚构桥梁,主桥上部为预应力混凝土连续刚构,下部为矩形空心薄壁墩,最高墩为107m,直径2.2 m的群桩基础;高墩采用自提式翻板施工方法、箱梁采用悬壁浇筑两“T”同步施工挂篮方法;成立现场工程质量实施小组,对现场安全、原材料质量等环节实施全过程质量安全管理和技术保证;从而加快了施工进度,确保了工程质量和施工安全,为连续刚构桥结构设计和施工质量控制积累了重要的工程经验。
“Henan first Takahashi ” every Shihe River Bridge is the largest continuous rigid frame bridge on the highway in Henan Province, the upper part of the main bridge is prestressed concrete continuous rigid frame, the lower part is rectangular hollow thin-walled piers, the highest pier is 107m, Diameter of 2.2 m pile foundation; high piers using self-lift flap construction method, the use of cantilever pouring two “T” synchronous construction hanging basket method; set up on-site project quality implementation team, on-site safety, raw material quality And other aspects of the implementation of the entire process of quality and safety management and technical assurance; thus speeding up the construction schedule to ensure the quality of the project and construction safety for the continuous rigid frame bridge structural design and construction quality control has accumulated important engineering experience.
