钢筋混凝土刚架拱桥现浇施工工艺主要是搭设满堂拱架,现浇拱片、横系梁混凝土,使主拱先合拢成单片拱片,然后安装微弯板、再浇筑混凝土填平层及桥面形成整体。文章通过某大桥满堂拱架现浇施工技术的实践,对此进行了详细阐述。
The construction steps in rigid-frame bridge construction are full framing erection, in-situ casting of arch rib and straining concrete beam, folding of the arch ribs into a whole arch together, installation of the minor angle block and concrete filling till the deck forms into an integrity.
