Suspension bridge channel type anchorage foundation and construction method
The invention discloses a suspension bridge channel type anchorage foundation which sequentially comprises a subbase, a carriageway anchor body and an anchorage concrete abutment pier from bottom to top, wherein the cross section of the carriageway anchor body is in an n shape, foundation bottom plates are arranged between the two sides of the lower end of the carriageway anchor body and the subbase respectively, and a traffic lane is formed between the carriagewayanchor body and the foundation bottom plates. The suspension bridge channel type anchorage foundation has the functions of a channel and an anchorage at the same time, can provide stable tensile resistance to stabilize the bridge, can enable vehicles to pass through the anchorage, and solves the problem of transverse deflection of a main cable under the condition that a route is located on an easement curve. The invention further discloses a corresponding suspension bridge channel type anchorage foundation construction method. According to the construction scheme, deep foundation pit excavation is avoided, foundation pit excavation is reduced, dewatering and drainage are easy in the construction period, the foundation construction difficulty is small, and the method is relatively more environmentally friendly.
本发明公开一种悬索桥通道式锚碇基础，由下至上依次包括有底基、行车道锚体和锚碇砼台墩，所述行车道锚体的截面呈“Π”形，所述行车道锚体下端的两侧与所述底基之间分别设有基础底板，所述行车道锚体与所述基础底板之间形成行车通道。本设计的悬索桥通道式锚碇基础同时具有通道和锚碇的作用，可以提供稳固的抗拉力来稳定桥梁，还可以使车辆从锚碇中通行，解决了路线位于缓和曲线条件下主缆横向偏角问题。本发明还公开相应的悬索桥通道式锚碇基础施工方法，其施工方案避免了深基坑开挖，减少基坑挖方，使施工期间降排水较容易，基础施工难度小，相对更加环保。
