在跨越既有线路的钢-混凝土组合连续箱梁施工中,针对悬臂现浇段侵入既有线路限界比较多、净空不够的桥梁,通过搭接式贝雷梁悬挑伸入既有线路搭设混凝土箱梁作业平台,利用上下搭接式贝雷梁提高既有线路位置支架底面标高,以满足净空要求,能保证线路运营和施工安全。
In the construction of steel-concrete composite continuous box girder across existing lines, in the case of in-situ cantilever intrusion into the existing lines more limited boundaries, insufficient clearance of the bridge, through the overhang Beilei cantilevered into the existing line set up concrete Box girder work platform, the use of upper and lower overlapping Beiliang improve the elevation of the floor of the existing line elevation bracket to meet the clearance requirements, to ensure the operation of the line and construction safety.
