Incremental launching construction method for small-radius steel box girder in cross-road section
The invention relates to a road-crossing section small-radius steel box girder incremental launching construction method which comprises the following steps: splicing steel box girders and mounting guide girders, namely hoisting the steel box girders to a steel box girder assembling bracket and a steel box girder incremental launching bracket to be assembled, and mounting the guide girders at the front ends of the assembled steel box girders; incremental launching construction is conducted, in the incremental launching process, the speed ratio of walking type incremental launching equipment on the inner arc side and the outer arc side of the steel box girder and the guide girder needs to be adjusted to achieve arc incremental launching, and the steel box girder and the guide girder are made to make arc movement gradually along the designed arc till the steel box girder and the guide girder move to the specified positions; the steps of section-by-section pushing, section-by-section lengthening and continuous pushing are adopted for construction in the pushing process, the weight of the pushing structure can be effectively reduced, temporary facility investment is reduced to the maximum extent, the construction period is shortened, meanwhile, in the arc pushing process, arc pushing can be achieved by adjusting the speed ratio of walking type pushing equipment on the inner arc side and the outer arc side through an arc-shaped guide beam, and the construction efficiency is improved. By means of the scheme, the construction difficulty is reduced, and meanwhile the construction quality and the construction period can be effectively guaranteed.
本发明涉及一种跨路地段小半径钢箱梁顶推施工方法，包括以下步骤：钢箱梁拼接及导梁安装，将钢箱梁吊装至钢箱梁组拼支架和钢箱梁顶推支架上拼装，并在拼装后的钢箱梁前端安装导梁；顶推施工，顶推过程中需调节钢箱梁及导梁内外弧侧步履式顶推设备的速比来实现圆弧顶推，使得钢箱梁和导梁沿着设计弧线逐渐做弧线移动，直至移动至规定位置；顶推过程采用逐段顶推、逐段接长、连续顶推的步骤施工，可有效减少顶推结构的重量，实现最大限度的减少临时设施投入并节约工期，同时在圆弧顶推过程中，可通过弧形导梁及调节内外弧侧步履式顶推设备的速比来实现圆弧顶推，通过如上方案减小了施工难度，同时施工质量及工期均可得到有效保证。
