Large-deformation reinforcing structure for road shoulder sheet-pile wall and construction method
The invention discloses a large-deformation reinforcing structure for a road shoulder sheet-pile wall and a construction method, aiming at effectively controlling the deformation of a reinforcing pile, and being convenient to construct and good in economical efficiency. The structure comprises existing reinforcing piles, embankment filling bodies and existing breast boards, wherein the existing reinforcing piles are arranged at intervals in the line direction, the lower portions of the existing reinforcing piles are buried in a foundation, the existing breast boards are arranged between the adjacent existing reinforcing piles, and the embankment filling bodies are filled on the portions, on the inner sides of the existing reinforcing piles and the existing breast boards, of the foundation in a layered mode. Reinforced concrete stress beams abutting against the existing reinforcing piles are arranged on the foundation on the outer sides of the existing reinforcing piles, supporting bodies are filled in gaps between the rear walls of the reinforced concrete stress beams and the front walls of the existing breast boards between the adjacent existing reinforcing piles, and reinforcing anchor cables with the axes inclining downwards are transversely arranged between the reinforcing piles at intervals. The inner end of the reinforcing anchor cable penetrates through the supporting body and the soil retaining plate to be anchored in the foundation, and the outer end of the reinforcing anchor cable is anchored on the reinforced concrete stress beam after prestress is applied.
一种路肩桩板墙大变形加固结构及施工方法，以使有效控制加固桩的变形，而且施工方便，经济性好。包括既有加固桩、路堤填筑体和既有挡土板，既有加固桩沿线路方向间隔设置，其下部埋入地基内，既有挡土板设在相邻既有加固桩之间，路堤填筑体分层填筑于既有加固桩、既有挡土板内侧的地基之上。既有加固桩的外侧地基上设置与各既有加固桩紧靠的钢筋混凝土受力梁，相邻既有加固桩之间在钢筋混凝土受力梁后壁与既有挡土板前壁之间的空隙内填筑支撑体，各加固桩之间横向间隔设置其轴线倾斜向下的加固锚索，加固锚索的内端穿过支撑体、挡土板锚固于地基内，施加预应力后加固锚索的外端锚固于钢筋混凝土受力梁上。
