Large-span longitudinal and transverse beam structure for assisting tunnel in underneath passing existing line track
The invention provides a large-span longitudinal and transverse beam structure for assisting a tunnel in underneath passing an existing line track. The structure comprises reinforced concrete longitudinal beams erected along the lower parts of the two sides of the existing line track, and the reinforced concrete longitudinal beams are erected on cast-in-situ bored piles; at least two of the cast-in-situ bored piles are located near the outer contour of the tunnel at the junction of an underpass tunnel and an existing line track, cross beams are erected between the reinforced concrete longitudinal beams at intervals, and steel rails of the existing line track are erected on the cross beams. The structure is reasonable in cost, convenient to construct and suitable for the longitudinal and transverse beam structure for assisting the tunnel to underpass the existing line track with the large cross span, and it is guaranteed that when the tunnel underpasses the existing railway line above, normal and safe operation of the existing railway line is conducted.
本发明提供一种辅助隧道下穿既有线轨道的大跨度纵横梁结构，包括沿既有线轨道两侧下方架设的钢筋混凝土纵梁，所述钢筋混凝土纵梁架设于钻孔灌注桩上，所述钻孔灌注桩中至少两根分别位于下穿隧道与既有线轨道交界的隧道外轮廓附近，所述钢筋混凝土纵梁之间间隔架设有横梁，既有线轨道的钢轨架设于所述横梁上。本发明成本合理、施工方便、适用于交叉跨度较大的辅助隧道下穿既有线轨道的纵横梁结构，保证隧道下穿上方既有铁路线施工时，既有铁路线正常安全运营。
