Bridge abutment back backfilling treatment construction framework and method based on formed abutment cap
The invention discloses a bridge abutment back backfilling treatment construction framework and method based on a formed abutment cap, and the construction framework comprises a bridge abutment foundation framework which is fixedly arranged on an excavation foundation pit; the paving and pressing cement soil layer is backfilled and paved in the foundation pit, and the paving and pressing cement soil layer forms a flow state backfilling groove area corresponding to the bridge abutment foundation structure; and the flow-state cement soil layer is arranged in the flow-state backfilling groove area in a pouring mode. The technical problems that in the prior art, when a bridge with a formed abutment cap is constructed, due to spatial constraint between the abutment cap and a bearing platform structure, the abutment back backfilling construction difficulty is increased, the backfilling construction period is prolonged, the construction efficiency is reduced, the overall girder erection construction progress is difficult to guarantee, and the engineering economy is not facilitated are solved.
本发明公开了一种基于已成型台帽的桥台台背回填处理施工架构及方法，包括：桥台基础架构，固定设于开挖基坑；铺压水泥土层，回填铺筑设于所述基坑，且所述铺压水泥土层对应于所述桥台基础架构形成有一流态回填槽区；流态水泥土层，浇筑设于所述流态回填槽区。解决了现有技术中在针对已成型台帽的桥梁施工时，受限于台帽与承台结构之间的空间约束导致对于台背回填的施工难度增大，回填施工周期延长，施工效率降低，难以保证整体架梁施工进度，不利于工程经济性的技术问题。
