River-adjacent existing roadbed embankment wall section widening structure and construction method
The invention provides a river-adjacent existing roadbed embankment wall section widening structure and a construction method, a concrete base is poured along the sideline of a widened roadbed, a concrete prefabricated baffle is arranged on the base along the longitudinal direction of the roadbed, and a vertical rod and a pull rod for reinforcing the baffle are arranged on the base; a plurality of steps are arranged on the existing roadbed slope, and foam light soil is filled between the baffles and the roadbed slope. The requirement of the baffles for bearing of the foundation is low, and when the broadened roadbed sideline is located on the side slope of the existing embankment, damage to the existing embankment is small; when the broadened roadbed side boundary coincides with the position of the existing embankment wall or is located in the river channel, the existing embankment wall does not need to be dismantled, the existing embankment wall can be fully utilized, treatment of the river channel foundation is avoided, construction investment can be reduced, and stability of the existing embankment is guaranteed.
本发明提供一种临河既有路基路堤墙段加宽结构及施工方法，沿加宽路基边线浇筑有混凝土基座，基座上沿路基纵向设有混凝土预制挡板，并设有加固挡板的立杆及拉杆；既有路基边坡上设有多级台阶，挡板与路基边坡之间填筑泡沫轻质土。本发明的挡板对基础的承载要求较低，当拓宽路基边线位于既有路堤边坡上时，对既有路堤破坏小；当拓宽路基边线与既有路堤墙位置重合或位于河道中时，无需拆除既有路堤墙，能充分利用既有路堤墙，避免了河道地基的处理，能降低施工投入，并保证既有路堤稳定。
