Space-limited inclined vertical pushing pier-side support
The space-limited inclined vertical pushing pier side support comprises a bearing platform, a pier body is arranged in the middle of the bearing platform, a vertical supporting structure is arranged around the outer ring of the pier body, the vertical supporting structure gradually inclines outwards in the direction from the bearing platform to the pier body, one end of the vertical supporting structure is fixed to the bearing platform, and the other end of the vertical supporting structure is fixed to the pier body. One end of the vertical supporting structure is fixed on the pier body through a pre-stress opposite-pulling structure, the other end of the vertical supporting structure is fixed on the pier body through a pre-stress opposite-pulling structure, and a buttress structure is further arranged between the vertical supporting structure and the pier body. Temporary structures are reduced, and the problem that the construction space is limited due to the fact that an old bridge is adjacent is solved; meanwhile, the structural form is simple and reasonable, safety and reliability are achieved, and the stress requirement of steel beam pushing can be met.
一种空间受限斜立式顶推墩旁支架包括承台，承台中部布设墩身，环墩身外圈布设竖向支撑结构，所述竖向支撑结构由承台向墩身方向逐渐外倾，所述竖向支撑结构的一端固定在承台上，所述竖向支撑结构的另一端通过预应力对拉结构固定在墩身上，所述竖向支撑结构、墩身之间还布设有扶墙结构，本发明以自有承台作为墩旁支架基础，不需要在墩旁重新打入桩和钻孔桩，减少临时结构避免了因毗邻老二桥导致施工空间受限的问题；同时，其结构形式简单合理、安全可靠能满足钢梁顶推的受力需求。
