Railway integral type jacking frame interchange system and construction method thereof
The invention relates to a railway integral jacking frame interchange system and a construction method thereof. In the jacking construction of an underpass interchange, the two sides of a construction frame interchange need to be constructed with an entrance and exit soil retaining splayed wall which is of an independent two-part structure, the step-by-step construction period is long, and the interference to the operation of a railway is large. The system comprises a frame body, the cross section of the frame body is rectangular, the two sides of the frame body are frame entrance and exit reinforced concrete triangular sections, a triangular steel shed frame is arranged on an inclined face, a beam top steel plate is arranged at the top of the triangular steel shed frame, and the beam top steel plate and the top of the frame body form the same sliding face. The entrance and exit reinforced concrete triangular section and the frame structure are integrally prefabricated, the stress performance is good, secondary pouring of an entrance and exit splayed wall is avoided, the frame entrance and exit reinforced concrete triangular section and the frame structure are jacked in place at a time, the construction period is short, safety is high, and good application and popularization value is achieved.
本发明涉及一种铁路整体式顶进框架立交体系及其施工方法。下穿立交顶进施工中，施工框架立交两侧需要构建出入口挡土八字墙，为独立的两部分结构，分步施工周期较长，对铁路的运营干扰性较大。本发明的体系包括框架主体，框架主体横截面呈矩形，两侧为框架出入口钢筋混凝土三角段，斜面上设置有三角形钢棚架，三角形钢棚架顶部设置有梁顶钢板，梁顶钢板与框架主体顶部组成同一滑动面。本发明的出入口钢筋混凝土三角段与框架结构整体预制，受力性能好，避免出入口八字墙二次浇筑，框架出入口钢筋混凝土三角段与框架结构一次顶进就位，施工周期短，安全性高，具有良好的推广使用价值。
