客运专线连续梁一次性整体支架现浇法施工

One-time overall support casting method construction on continuous beam in passenger line

针对哈大客运专线宫房特大桥跨越公路施工的工程特点,对现浇混凝土连续箱梁一次性整体支架现浇法进行了介绍,具体阐述了施工工艺和安全组织及措施,经实践证明采用一次性整体支架现浇法浇筑连续梁提高了制梁速度、确保了施工工期。

In light of the project characteristics of the construction on Gongfang large Bridge across highway of Ha-Da passenger line, it introduces one-time overall support beam casting method to cast concrete continuous beam, and describes construction technology and sate organizations and measures in detail. Practice shows that： beam-making speeded is increased through adopting one-time overall support casting method to cast continuous beam, and the construction period is also ensured.
