Space rigid frame bridge crossing existing special line and construction method
The invention provides a spatial rigid frame bridge crossing an existing special line, which comprises a main span, the main span obliquely crosses the existing special line, and the two ends of the main span extend to the two sides of the existing special line along a preset path until the side edge in the width direction of the main span is separated from the roadbed range of the existing special line; the auxiliary span extends in the extension direction of the existing special line, and a settlement joint is arranged between the auxiliary span and the main span; side walls located on the two sides of the existing special line are arranged on the two sides of the auxiliary span, so that a train channel is formed above the existing special line; rigid wall piers connected with the side walls on the two sides of the auxiliary span into a whole are arranged below the main span, and the shape of the rigid wall piers is matched with the shape of the parts, located on the two sides of the auxiliary span, of the main span. The main span and the auxiliary span are arranged, the main span is used for spanning the existing special line and bearing the newly-repaired high-speed rail line, the auxiliary span is used for protecting the existing special line, the high-speed rail line and the existing special line form vertical crossing, the high-speed rail line and the existing special line have independent operation spaces, and therefore interference of the high-speed rail line on the existing special line is reduced.
本发明提供一种跨既有专线的空间刚构桥，包括：主跨，主跨倾斜跨越既有专线，主跨两端沿预设路径向既有专线的两侧延伸，直至主跨宽度方向的侧沿脱离既有专线的路基范围；副跨，副跨沿既有专线的延伸方向进行延伸，副跨与主跨间设置沉降缝；其中，副跨的两侧设有位于既有专线两侧的侧墙，以在既有专线的上方形成列车通道；主跨的下方设有与副跨两侧的侧墙连为一体的刚壁墩，刚壁墩形状与主跨位于副跨两侧部分形状相适配。设置主跨和副跨，主跨用于跨越既有专线，用于承载新修的高铁线路，通过副跨对既有专线进行保护，使高铁线路和既有专线形成立体交叉，二者具备独立的运行空间，从而降低高铁线路对既有专线的干扰。
