Toe-crossing board traffic structure and construction method thereof
The invention provides a toe board crossing traffic structure which is characterized in that a dam upstream abutment and an in-dam abutment are arranged on the upstream side and the downstream side of a toe board respectively, a traffic bridge is erected on the dam upstream abutment and the in-dam abutment, and the traffic bridge is communicated with a dam upstream construction road and an in-dam construction road; an excavation foundation is arranged on a toe board below a path of the traffic bridge, a toe board bridge abutment is arranged on the excavation foundation, the traffic bridge comprises an upstream bailey bridge and a downstream bailey bridge, and the upstream bailey bridge and the downstream bailey bridge are connected with an upstream bridge abutment and an in-dam bridge abutment of a dam respectively through the toe board bridge abutment. The toe board bridge abutment is arranged at the toe board and serves as a middle pier of the bailey bridge, the cross toe board traffic bridge is divided into two sections, the overall span of the bailey bridge is shortened, the structures and shapes of the upstream and downstream piers are simplified, the pier at the downstream side dam body part keeps a proper space with the panel, and by means of the deformation coordination capacity of rockfill materials, the cross toe board traffic bridge is formed. The problem of panel stress is solved.
本发明提供了一种跨趾板交通结构，在趾板的上下游侧分别设置大坝上游桥台和坝内桥台，所述大坝上游桥台和坝内桥台上架设交通桥，所述交通桥连通大坝上游施工道路和坝内施工道路，所述交通桥在其路径下方的趾板上设置开挖基础，所述开挖基础上设置趾板桥台，所述交通桥包括上游贝雷桥和下游贝雷桥，所述上游贝雷桥和下游贝雷桥通过趾板桥台分别连接大坝上游桥台和坝内桥台。本发明通过在趾板处设置趾板桥台，趾板桥台作为贝雷桥中间桥墩，将垮趾板交通桥分隔成两段，缩短贝雷桥整体跨度，简化上下游桥墩结构和体型，下游侧坝体部位的桥墩保持与面板之间适当的空间，利用堆石料自身的变形协调能力，解决面板受力问题。
