Existing-newly-built side-by-side sheet-pile wall retaining structure and construction method
The invention provides an existing-newly-built side-by-side combined embankment pile sheet wall retaining structure and a construction method. The structure comprises existing pile bodies, existing breast boards, newly-built pile bodies and newly-built breast boards, the newly-built pile bodies are arranged between the adjacent existing pile bodies, the pile tops of the newly-built pile bodies arehigher than the pile tops of the existing pile bodies, the anchoring depth of the newly-built pile bodies is larger than that of the existing pile bodies, and the newly-built breast boards are arranged over the existing breast boards and located in the same plane. The side pressure shared by the newly-built breast board is borne by the new pile, the side pressure shared by the existing breast board is borne by the newly-built pile body and the existing pile body jointly, and the newly-built pile body and the existing pile body cooperate. According to the structure, the bearing effect of an existing pile plate wall is fully played, meanwhile, the requirements of a newly-built roadbed for strength, rigidity and stability are met, and the influence of construction of the newly-built pile plate wall on an existing line is within a controllable range.
本发明提供了一种既有‑新建并排组合路堤桩板墙支挡结构及施工方法。该结构包括既有桩体、既有挡土板、新建桩体和新建挡土板，新建桩体设置在相邻既有桩体中间，新建桩体桩顶高于既有桩桩顶，且新建桩体锚固深度大于既有桩体，新建挡土板设置在既有挡土板正上方，两者处于同一平面内。新建挡土板分担的侧压力由新桩承担，既有挡土板分担的侧压力由新建和既有桩体共同承担，两者协同作用。该结构充分发挥了既有桩板墙的承载作用，同时又满足了新建路基对强度、刚度和稳定性的要求，且新建桩板墙的施工对既有线路的影响在可控范围内。
