Concrete-filled steel tube temporary consolidation pier for construction of girder cantilever of cable-stayed bridge
The invention discloses a concrete filled steel tube temporary consolidation pier for cable-stayed bridge girder cantilever construction, which comprises a permanent pier base, a permanent pier body is arranged on the permanent pier base, and three pouring steel tubes are mounted on the permanent pier base and positioned on two sides of the permanent pier body. An upper combined supporting structure is connected between the tops of the pouring steel pipes, a supporting platform connected with the permanent pier body is installed on the upper combined supporting structure, and vertical supporting columns are connected between the bottom of the supporting transverse plate and the supporting platform. The construction method has the beneficial effects that the permanent pier base is matched with the permanent pier body to serve as a foundation, the overall bearing capacity and rigidity of the cast steel pipe are improved, the cast steel pipe can meet the requirement for long cantilever construction, the concrete-filled steel pipe temporary consolidation pier does not need to utilize the permanent pier top space, the construction space is reduced, and the construction method can be used for building a supporting platform; and the construction difficulty is reduced, and high applicability and universality are achieved.
本发明公开了一种斜拉桥主梁悬臂施工用钢管混凝土临时固结墩，包括永久桥墩底座，所述永久桥墩底座上设有永久桥墩本体，所述永久桥墩底座上位于所述永久桥墩本体的两侧安装有三根浇筑钢管，所述浇筑钢管的顶部之间连接有上组合支撑结构，所述上组合支撑结构上安装有与所述永久桥墩本体连接的支撑平台，所述支撑横板的底部与所述支撑平台之间连接有竖向支撑柱，有益效果：本申请利用永久桥墩底座配合永久桥墩本体作为基础，提高浇筑钢管整体的承载力以及刚度，使其能满足长悬臂施工所需，钢管混凝土临时固结墩不需要利用永久墩顶空间，减小了施工空间，还可以用于搭建支撑平台，减小了施工难度且具有较强的适用性及通用性。
