摘要
官盛渠江大桥主桥为320m跨径的钢筋混凝土中承式拱桥,拱圈由C100钢管砼劲性骨架外包C50砼形成。本文从C100砼配合比设计、泵送施工工艺等方面对官盛渠江大桥劲性骨架内灌C100混凝土材料的制备技术和灌注工艺进行了探讨。
the main bridge of the Guan Sheng canal river bridge is a 320 m span reinforced concrete middle bearing arch bridge. The arch is formed by the C100 steel tube concrete stiffening skeleton outsourced C50 concrete. From the aspect of C100 concrete mix design and pumping construction technology,the preparation technology and pouring process of C100 concrete material for the internal skeleton of the Guan Sheng River Bridge are discussed in this paper.
