Gravity type anchorage structure of splay saddle buttress foundation and approach bridge foundation and construction method
The invention relates to the field of suspension bridge anchoring system construction, in particular to a gravity type anchorage structure of a splay saddle buttress foundation and approach bridge foundation and a construction method. The gravity type anchorage structure comprises an anchor block; splay saddle buttresses which are arranged on the anchor blocks, and approach bridge piers are arranged on the splay saddle buttresses; and side walls which are arranged on the anchor blocks. The construction method comprises the following steps that 1, treating a drainage system through a base; 2, pouring a cushion layer; 3, pouring anchor blocks, splay saddle buttresses and foundations of the splay saddle buttresses layer by layer and block by block; 4, pouring a post-cast strip; and 5, constructing a splay saddle buttress and a side wall. The splay saddle buttress foundation and the approach bridge pier form a composite structure, the composite structure bears force from the approach bridge and the splay saddle at the same time, the bearing capacity of the splay saddle buttress can be improved, the safety of the anchorage foundation is guaranteed, the construction period can be shortened, and the construction cost is reduced.
本发明涉及悬索桥锚固系统施工领域，特别是涉及一种散索鞍支墩基础兼引桥基础的重力式锚碇结构及施工方法。所述重力式锚碇结构包括锚块；散索鞍支墩，所述散索鞍支墩设置在所述锚块上，所述散索鞍支墩上设有引桥桥墩；侧墙，所述侧墙设置在所述锚块上。所述施工方法包括如下步骤：步骤1：基底处理排水系统；步骤2：垫层的浇筑；步骤3：分层、分块浇筑锚块和散索鞍支墩及其基础；步骤4：后浇带浇筑；步骤5：散索鞍支墩和侧墙的施工。本发明通过将散索鞍支墩基础与引桥桥墩组成复合结构，复合结构同时承受分别来自引桥和散索鞍的力，不仅能够提高散索鞍支墩的承载力，保证锚碇基础的安全性，又能缩短工期，降低工程造价。
