Railway track temporary supporting structure and construction method thereof
The invention discloses a railway track temporary supporting structure which comprises a plurality of fulcrum piles, the fulcrum piles are vertically arranged between an existing railway track and a newly-built tunnel, and the fulcrum piles are evenly arranged along the existing railway track at intervals. The longitudinal supporting beams are horizontally arranged at the upper parts of the fulcrum piles and are arranged in parallel along the direction of the existing railway track; transverse supporting beams are arranged at the intersection points of the fulcrum piles and the longitudinal supporting beams and arranged between the fulcrum piles and the longitudinal supporting beams. A plurality of transverse distribution beams are arranged between every two adjacent transverse supportingbeams; the fulcrum piles, the longitudinal supporting beams, the transverse supporting beams and the transverse distribution beams are combined to form an overhead stress structure; load of the existing railway track is transmitted to the overhead stress structure, settlement of the existing railway track is effectively reduced, the temporary supporting structure is removed after a newly-built tunnel penetrates through an existing railway track section in construction, beneficial construction conditions are provided for tunnel construction, and safety, stability and durability of the existingrailway track are guaranteed.
本发明公开了一种铁路轨道临时支护结构，包括若干支点桩，若干支点桩竖向设置在既有铁路轨道与新建隧道之间，若干支点桩沿既有铁路轨道均匀间隔设置；纵向支撑梁水平设置在支点桩的上部，且沿既有铁路轨道方向平行设置；支点桩与纵向支撑梁的交点处设置横向支撑梁，横向支撑梁设置在支点桩与纵向支撑梁之间；相邻两根横向支撑梁之间设置有若干横向分布梁；本发明利用支点桩、纵向支撑梁、横向支撑梁及横向分布梁组合形成架空受力结构；将既有铁路轨道荷载传递至架空受力结构上，有效减少了既有铁路轨道沉降，待新建隧道施工穿过既有铁路轨道区段后再拆除临时支护结构，为隧道施工提供有利施工条件，保证了既有铁路轨道的安全性、稳定性和耐久性。
