Steel beam pushing method for transverse widening and longitudinal slope changing
The invention relates to a steel beam pushing method for transverse widening and longitudinal slope changing, which comprises the following steps of dividing a bridge into a plurality of pushing sections, arranging a temporary pushing buttress on each pushing section, and arranging an assembling platform, a pushing device and a lifting station in each pushing section, assemblingsteel beam sectionson the assembling platform, installing guide beams on the assembling platform, pushing the steel beam sections on the assembling platform out of the assembling platform, continuously assembling the steel beam sections on the assembling platform, pushing the steel beam sections out of the assembling platform, and repeatedly assembling and pushing the steel beam sections until all the steel beams in the pushing sections are pushed, after the steel beams are laid in the first pushing section, repeating the pushing action in the other pushing sections until the steel beams in each pushing sectionare completely pushed, and finally, removing the guide beams and the temporary pushing buttresses, and cutting off the steel beams at the positions of all the expansion joints. The method can effectively solve the problem of planar linear control such as transverse widening or longitudinal slope changing, and is high in practicability.
本发明涉及一种用于横向变宽与纵坡变化的钢梁顶推方法，包括以下步骤：先将桥梁划分若干顶推段，在每个顶推段上设置临时顶推支墩，在每个顶推段中还设置有拼装平台、顶推装置及提升站；然后在拼装平台上拼装钢梁段及安装导梁；再将拼装平台上的钢梁段推出拼装平台；然后在拼装平台上继续拼装钢梁段，并将其顶推出拼装平台，重复拼装、顶推，直至顶推段中的钢梁全部被顶推完成；再当首个顶推段中铺设完成钢梁后，在其他顶推段中重复顶推动作，直至每个顶推段中的钢梁全部被顶推完成；最后拆除导梁及临时顶推支墩，并将钢梁在每联伸缩缝位置处进行切割断开。本发明能够有效解决横向变宽或纵坡变化等平面线型控制问题，实用性强。
