Steel box girder installation and construction method for crossing existing high-speed short-time traffic interruption implementation
The invention relates to the technical field of high-speed construction, in particular to a method for installing and constructing a steel box girder across existing high-speed short-time traffic interruption, which comprises the following steps of: S1, before processing and manufacturing the steel box girder, strictly inspecting and measuring a construction site; especially for the plane position and width of the existing high-speed medial strip, the plane positions of wave-shaped guardrails on the two sides of the road and the terrain elevation; s2, according to the measured data, carrying out steel box girder longitudinal segment division on the steel box girder bridge, and numbering and arranging; s3, after longitudinal segments of the steel box girder are divided and determined, each segment is decomposed into a plurality of transverse unit bodies, and the transverse unit bodies are numbered and arranged; s4, installing a temporary support at the medial strip of the existing expressway; and S5, mounting the half-range steel box girder unit bodies crossing the high speed hole by hole according to the erection sequence (segment division sequence). According to the method, the influence on the existing high-speed normal traffic can be reduced, the process is simple and convenient to implement, and compared with an integral hoisting mode, the construction cost is reduced.
本发明涉及高速施工技术领域，具体为一种跨既有高速短时中断交通实施钢箱梁安装施工方法，包括以下步骤:S1、钢箱梁加工制作前，对施工现场进行严密考察、测量，尤其对于既有高速中央分隔带的平面位置及宽度、道路两侧波形护栏的平面位置、地形标高；S2、根据所测量数据，对钢箱梁桥进行钢箱梁纵向节段划分，并编号排列；S3、钢箱梁纵向节段划分确定后，再将每个节段分解成若干个横向单元体，并编号排列；S4、安装既有高速公路中央分隔带处的临时支撑；S5、按照架设顺序（节段划分顺序）逐孔安装跨高速的半幅钢箱梁单元体。本发明通过上述方法能够减少对既有高速正常通车的影响，工序简单，便于实施，相较于整体吊装方式，降低施工成本。
