Incremental launching construction method of steel truss girder bridge
The invention discloses an incremental launching construction method of a steel truss girder bridge, which comprises the following steps of: (1) simultaneously installing steel truss girder incremental launching assembly platforms on two sides of the bridge, and installing pier-side auxiliary brackets and incremental launching alignment equipment; (2) a track beam and a steel truss beam with the length of one span are assembled at the same time, and a first pushing mechanism is installed; (3) simultaneously pushing the steel truss girder from the two sides of the bridge position to the middle position along the longitudinal bridge by utilizing a first pushing mechanism; (4) after primary pushing is completed, the pushing auxiliary structure is controlled to pull the first pushing mechanism in the longitudinal bridge direction; (5) splicing a steel truss girder with the length of the next span at the rear part of the steel truss girder, and mounting a second pushing mechanism at the bottom of the steel truss girder with the length of the next span; and (6) the steps (3)-(5) are repeated till the steel truss girder bridge is pushed in place, and closure is completed. The method is easy to operate, the construction cost is saved, the construction period is shortened, the incremental launching process is stable, and construction safety and linear reasonability of the steel truss girder bridge are guaranteed.
本发明公开了一种钢桁梁桥的顶推施工方法，包括以下步骤：(1)在桥梁两侧同时安装钢桁梁顶推拼装平台，并安装墩旁辅助支架和顶推对准设备；(2)同时拼装轨道梁以及一跨长度的钢桁梁，并安装第一顶推机构；(3)同时在桥梁位置的两侧利用第一顶推机构沿纵桥向中间位置顶推钢桁梁；(4)完成一次顶推后，控制顶推辅助结构将第一顶推机构沿纵桥向牵引；(5)在上述钢桁梁的后部拼接下一跨长度的钢桁梁，并在下一跨长度的钢桁梁的底部安装第二顶推机构；(6)重复步骤(3)‑(5)，直至钢桁梁桥顶推到位，完成合龙。本发明的方法操作简单，节省施工成本，缩短了工期，顶推过程平稳，保证了施工安全以及钢桁梁桥的线性合理。
