Reinforcing structure of railway turnout zone and frame bridge structure passing through existing railway underneath
The embodiment of the invention provides a reinforcing structure of a railway turnout zone and a frame bridge structure penetrating through an existing railway. The reinforcing structure of the railway turnout zone is used for underneath passing through a frame bridge of an existing railway, and the reinforcing structure comprises a plurality of pile foundations, a plurality of cross beams, a plurality of longitudinal beams and overhead supporting beams. The multiple pile foundations are sequentially arranged along the two sides of the railway. The multiple cross beams extend along the crossing railway and are used for bearing the rail bottom or the sleeper bottom of an existing sleeper. The two ends of each cross beam are supported on a guard pile foundation, and the cross beams are disconnected at the area where a pull rod of a railroad switch is arranged. The longitudinal beams extend in the railway direction, are arranged above the cross beams and are connected with the cross beams, and the longitudinal beams are disconnected in the switch area. The overhead supporting beams extend in the railway direction and are arranged below the railroad switch at intervals, and the two ends of each overhead supporting beam are connected with the cross beams on the two sides of the railroad switch respectively. By the adoption of the scheme, the strength and rigidity of the turnout zone in construction of the frame bridge can be guaranteed, and driving safety is guaranteed.
本申请实施例中提供了一种铁路道岔区的加固结构及下穿既有铁路的框架桥结构。其中，铁路道岔区的加固结构，用于下穿既有铁路的框架桥，该加固结构包括多个桩基础、多根横梁、多根纵梁和架空支撑梁。多个桩基础沿铁路的两侧依次设置。多根横梁沿横跨铁路延伸，用于承托轨底或既有轨枕的枕底。横梁的两端支撑在防护桩基础上，横梁在设置有转辙器的拉杆的区域处断开。多根纵梁沿铁路方向延伸，纵梁设置于横梁的上方并且与横梁连接，纵梁在转辙器区域断开。架空支撑梁沿铁路方向延伸，架空支撑梁间隔设置于转辙器的下方，架空支撑梁的两端分别与转辙器两侧的横梁连接。采用上述方案，能够保证框架桥的施工中道岔区的强度和刚度，确保行车安全。
