摘要： A method for assembling a segment girder in a bridge is provided to combine a middle fixing segment with side movable segments conveniently and safely by manufacturing the segments with prestressed concrete beams. A steel beam(200) is installed longitudinally on a worktable(100), and a middle fixing segment(300a) is mounted on the steel beam. A sheath pipe(330) for a tendon(320) is laid in the lower part of the middle fixing segment, and side movable segments(300b) are set at sides of the middle fixing segment and placed on a moving unit(400). The moving unit is formed by attaching a roller to a latticed frame. The tendon is inserted to the sheath pipe laid in the middle fixing and side movable segments, and the side movable segments are combined with the middle fixing segment by straining both ends of the tendon. The height of the middle fixing segment is adjusted by mounting a hydraulic jack in the lower part of the middle fixing segment.
摘要翻译：提供一种在桥梁中组装段梁的方法，通过用预应力混凝土梁制造段，方便安全地组合中间固定段与侧可移动段。钢梁（200）纵向安装在工作台（100）上，中间固定段（300a）安装在钢梁上。用于腱（320）的护套管（330）被放置在中间固定段的下部，侧面可动段（300b）设置在中间固定段的侧面并放置在移动单元（400）上。移动单元通过将滚子附接到网格框架而形成。将肌腱插入到位于中间固定和侧面可动节段中的鞘管中，并且通过使筋腱的两端紧固，将侧面可动部分与中间固定部分组合。通过将液压千斤顶安装在中间固定段的下部来调节中间固定段的高度。

摘要： A construction method of a channel bridge for correcting sag is provided to construct the channel bridge securely and accurately by longitudinally prestressing U-shaped segments in restricting subsidence of the U-shaped segments supported in a temporary beam. Temporary beams(320) are longitudinally and successively installed on a temporary lower structure(310) with temporary bents spaced longitudinally, and a rail member(323) is mounted in the temporary beam. A lifting unit(400) with a hydraulic jack is installed in an upper part of a trolley(330) moving along the rail member, and a U-shaped segment(100) is loaded in the trolley and directly supported in the lifting unit. Plural U-shaped segments are integrally connected by pushing the trolley forward along the temporary beam, and sag of the U-shaped segment is corrected by operating the lifting unit. A tendon(500) penetrating the U-shaped segments is strained and fixed to support a lower bridge structure with the U-shaped segments. The U-shaped segment is supported in the lifting unit, and moved along the rail member of the temporary beam with the trolley.
摘要翻译：提供了一种用于校正下垂的通道桥的施工方法，通过纵向预应力的U形段来稳定而准确地构造通道桥，以限制支撑在临时梁中的U形段的沉降。临时梁（320）纵向并连续地安装在临时下部结构（310）上，临时横梁纵向间隔开，并且轨道构件（323）安装在临时梁中。具有液压千斤顶的提升单元（400）安装在沿着轨道构件移动的手推车（330）的上部，并且U形段（100）被装载在手推车中并直接支撑在提升单元中。多个U形段通过沿着临时梁向前推动手推车而一体地连接，并且通过操作提升单元来校正U形段的松弛。穿过U形段的腱（500）被应变并固定以支撑具有U形段的下桥结构。 U形节段被支撑在提升单元中，并且沿着具有手推车的临时梁的轨道构件移动。
