Deep foundation pit anchorage and construction method
The invention relates to the technical field of bridge engineering, and discloses a deep foundation pit anchorage and a construction method. The deep foundation pit anchorage comprises a construction foundation, a foundation top plate, a saddle weight, a splay saddle buttress, and an anchor chamber; the construction foundation is buried underground; the foundation top plate is arranged at the top of the construction foundation and extends out in the direction away from a bridge; the saddle weight is arranged on the upper surface of the extending part of the foundation top plate; the splay saddle buttress is arranged at the top of the foundation top plate, located above the construction foundation and used for being connected with a bridge cable; and the saddle weight and the splay saddle buttress are fixedly connected through the anchor chamber. The deep foundation pit anchorage and the construction method have the following advantages and effects that compared with a traditional construction foundation anchorage structure, the gravity center of the whole anchorage is moved backwards through postposition and jetting out of the saddle weight, the plane size of the construction foundation can be reduced under the same external condition while no tensile stress occurs on an anchorage base, construction excavation is reduced, and finally the purposes of reducing the construction cost and shortening the construction period are achieved.
本发明涉及桥梁工程技术领域，公开了一种深基坑锚碇及施工方法，包括：施工基础，埋设于地面之下；基础顶板，设置于施工基础的顶部，并朝着远离桥梁方向伸出；压重块，其设置于基础顶板伸出部分的上表面；散索鞍支墩，其设置于基础顶板的顶部，并位于施工基础的上方，用于和桥索连接；锚室，其将压重块和散索鞍支墩固定连接。本发明具有以下优点和效果：本申请的深基坑锚碇及施工方法，相比于传统施工基础锚碇结构，通过压重块后置外挑使得整个锚碇重心后移，实现锚碇基底不出现拉应力的情况同时可在同等外界条件下，减小施工基础平面尺寸，减少施工开挖，最终实现降低工程造价、节约施工工期的目标。
