Bridge foundation protection structure for abrupt slope terrain and construction method
The invention discloses an abrupt slope terrain bridge foundation protection structure and a construction method, and the abrupt slope terrain bridge foundation protection structure comprises an enclosing wall structural body which is arranged on a side slope around a bridge pier and abutment foundation; anchoring structural bodies which are arranged at intervals in the wall surface direction of the enclosing wall structural body, and the two ends of each anchoring structural body are anchored and fixed to the enclosing wall structural body and the side slope correspondingly; lightweight concrete which is arranged in a three-dimensional space formed by the enclosing wall structural body and the side slope; a bridge pile foundation which penetrates through the lightweight concrete, and the lower portion of the bridge pile foundation enters the slope stable area; and a bridge bearing platform which is arranged at the top of the bridge pile foundation and fixedly connected with the bridge pile foundation. The construction platform formed by the enclosing wall structural body and the lightweight concrete is arranged on the side slope of the abrupt slope terrain, so that the problem that the bridge pile foundation and the bearing platform are difficult to construct is solved, and the problems that a high side slope needs to be reinforced and excavated when the bridge foundation construction platform is built through slope cutting and the engineering investment is high are solved; the problems of insufficient rigidity and difficult deformation control caused by a traditional high pile foundation bearing platform of a bridge are solved.
本发明公开了一种陡坡地形桥基防护结构及构筑方法，其中陡坡地形桥基防护结构包括围墙结构体，设置在桥梁墩台基础周围的边坡上；锚固结构体，顺着围墙结构体墙面方向间隔布置，且锚固结构体的两端分别与围墙结构体、边坡锚固固定；轻质混凝土，设置在围墙结构体与边坡形成的立体空间内；桥梁桩基，穿过轻质混凝土，且下部进入边坡稳定区域中；桥梁承台，设置在桥梁桩基顶部，并与桥梁桩基固定连接。本发明通过在陡坡地形的边坡上设置由围墙结构体和轻质混凝土形成的施工平台，解决桥梁桩基和承台施工困难问题，避免了切坡修建桥梁基础施工平台需要加固开挖高边坡及工程投资高的问题，解决了桥梁传统高桩基承台造成的刚度不足和变形控制困难问题。
