Eccentric counterweight type ballastless track widening roadbed structure and construction method
The invention relates to the technical field of ballastless track railroad beds, in particular to an eccentric counterweight type ballastless track widening roadbed structure and a construction method. The widening roadbed structure is arranged on the outer side of an existing drainage ditch and comprises a concrete frame, a top plate and a plurality of pile foundations, the pile foundations are embedded in a foundation on the outer side of an existing embankment, the concrete frame is arranged on the outer side of the existing embankment, the bottom of the concrete frame is connected with the pile foundations, and the top plate is arranged on the concrete frame and one end of the top plate extends to be connected to the existing embankment. A balance weight body is arranged in the concrete frame, a cavity used for laying and overhauling comprehensive pipelines is formed between the balance weight body and the inner side wall face of the concrete frame, and a foundation bed surface layer is arranged at the upper end of the top plate. The drainage condition of the existing line is ensured; the balance weight body is arranged in the concrete frame, the gravity center and load distribution of the roadbed structure can be adjusted through balance weight of the balance weight body, the overall load of the roadbed structure is reduced, the additional load on the existing line is reduced, and settlement and deformation of the existing line and the widening roadbed are effectively controlled.
本发明涉及无砟轨道铁路路基技术领域，尤其涉及一种偏心配重式无砟轨道帮宽路基结构及施工方法；该帮宽路基结构设置在既有排水沟外侧，包括混凝土框架、顶板和若干个桩基，桩基埋设在既有路堤外侧的地基内，混凝土框架设置在既有路堤外侧且底部与桩基连接，顶板设置在混凝土框架上且一端延伸连接于既有路堤上，混凝土框架内设置有配重体，配重体与混凝土框架的内侧壁面之间设有用于综合管线布设和检修的空腔，顶板的上端设置有基床表层。本申请保证了既有线排水条件；在混凝土框架内设置配重体，可以利用配重体的配重调节路基结构重心和荷载分布，降低路基结构整体荷载，减小对既有线的附加荷载，有效控制既有线与帮宽路基的沉降和变形。
