山区组拼式桁架箱梁外侧模整体推拉向前施工工法

Mountain spellers truss girder lateral mode of push-pull forward construction methods as a whole

对钢桁架、倒角钢模、方木及竹胶板面板在地面平整场地上的组拼进行了介绍,总结了通过吊车将各节段吊装至首件梁支架上进行逐节拼装完成梁体制作的施工要点,并利用人工或小卷扬机牵引作用而逐孔向前进行拆装作业,采用该方法进行桥梁施工不仅加快了施工进度,而且节约了成本。

The paper introduces the construction points of steel truss, chamfering steel mould, square wood and bamboo surface glue board on the plain ground, summarize the eonstruction points of crane will each segment lifting to the first beam bracket and segmental assembling beam production, carries out dismantle work with artificial or small winch drag, which not only speeds up construction schedule, but also saves cost.
