Construction method of variable-width variable-inclination-angle steel box girder for road turning
The invention provides a construction method of a variable-width variable-inclination-angle steel box girder for highway turning, which comprises the following steps: S1, mounting a temporary bracket according to the segmentation condition of the steel box girder, and adopting a concrete foundation as a lower foundation of the temporary bracket; s2, hoisting equipment is adopted for hoisting the segmented steel box girders one by one, axis deviation and elevation need to be checked for segmented hoisting and positioning, and after checking is qualified, positioning horse plates are adopted for temporarily fixing the steel box girder segments; s3, after positioning of the steel box girder is completed, welding seams between the sections of the steel box girder are welded; and S4, after welding is completed, anti-corrosion treatment is conducted on the whole steel box girder. According to the construction method of the variable-width variable-inclination-angle steel box girder for the road turning, corresponding foundation treatment measures are taken according to the conditions of foundations where different temporary supports are located according to local conditions, the construction cost is reduced, and the construction efficiency is improved.
本发明提供了一种公路拐弯变宽变倾斜角钢箱梁的施工方法，S1、根据钢箱梁分段情况进行临时支架安装，且临时支架下部基础采用混凝土基础；S2、采用吊装设备对分段的钢箱梁进行逐个吊装，分段吊装定位需检查轴线偏差及高程，检查合格后采用定位马板将钢箱梁分段进行临时固定；S3、钢箱梁定位完成后，进行钢箱梁分段之间的焊缝进行焊接；S4、焊接完成后对钢箱梁整体进行防腐处理。本发明所述的公路拐弯变宽变倾斜角钢箱梁的施工方法，因地制宜，根据不同的临时支架所处地基情况采取相对应的地基处理措施，降低施工成本，提高施工效率。
