Construction method for closing stiffening frameworks in steel tube arch bridge
The invention discloses a construction method for closing a stiffening framework in a steel tube arch bridge, which comprises the following steps of: temporarily placing a plurality of longitudinal stiffening plates and a plurality of annular stiffening plates, dragging out the plurality of longitudinal stiffening plates (5) at one end along the inner wall of a chord tube (1) of an arch rib at one end, separating from a stacking plate (7), and overlapping with the chord tube (1) of an arch rib at the other end of the opposite bank; the longitudinal stiffening plates (5) are inserted into the chord pipe (1) of the arch rib at the other end of the opposite bank, the longitudinal stiffening plates and the annular stiffening plates are installed, and the closure opening wrapping plate is installed. The inner stiffening frameworks are folded, the stiffening plates are welded, the requirement for high-altitude butt joint precision is not high, operation is convenient, the buckle cables do not need to be measured and adjusted repeatedly, folding construction is carried out in time, and the construction safety risk is reduced.
本发明公开了一种钢管拱桥内加劲骨架合拢的施工方法，包括以下步骤：若干纵向加劲板、若干环向加劲板临时放置，将一端若干纵向加劲板（5）沿一端拱肋的弦管（1）内壁拖出脱离码板（7）并与对岸另一端拱肋的弦管（1）搭接，使若干纵向加劲板（5）插入对岸另一端拱肋的弦管（1）内，安装若干纵向加劲板、若干环向加劲板，安装合拢口包板。本发明采用内加劲骨架合拢，加劲板采用焊接方式，对高空对接精度要求不高，便于操作，不用反复去测量和调整扣索，及时实施合拢施工，降低施工安全风险。
