Foundation structure of rigid tied-arch bridge cable hoisting tower and construction method of foundation structure
The invention discloses a rigid tied-arch bridge cable hoisting tower foundation structure and a construction method thereof. The construction method comprises the following construction steps: step 1, calculating the stress of the tower foundation structure, designing the size of the tower foundation structure, and integrally designing foundation concrete of a left tower foundation and a right tower foundation; secondly, foundation pit excavation is conducted according to the design form; thirdly, an abutment is poured, and a stand column positioning steel plate is pre-buried; fourthly, pre-embedded stand columns are installed on the stand column positioning steel plates, and positioning frameworks are welded to the pre-embedded stand columns; 5, binding foundation steel bars, reserving a balance cable reserved hole channel in the middle of the foundation concrete, and integrally pouring the foundation concrete; and sixthly, after the foundation concrete is maintained to be qualified, corresponding stand columns, transverse bracings, inclined struts and gusset plates are installed on the pre-embedded stand columns and the balance cable reserved hole channels. According to the technology, the tower foundation and the balance cable anchoring structure are designed in a fused mode, and the balance cable anchoring function is achieved while the requirement of the tower foundation is met.
本发明公开一种刚性系杆拱桥缆索吊装塔架基础结构及其施工方法，其施工步骤为：步骤一、进行塔架基础结构受力计算，设计塔架基础结构尺寸，左幅塔架基础和右幅塔架基础的基础混凝土整体设计；步骤二、按照设计形式进行基坑开挖；步骤三、浇筑墩台，预埋立柱定位钢板；步骤四、在立柱定位钢板上安装预埋立柱，在预埋立柱上焊接定位骨架；步骤五、绑扎基础钢筋，在基础混凝土的中间位置预留平衡索预留孔道，整体浇筑基础混凝土；步骤六、在基础混凝土保养合格后，在预埋立柱及平衡索预留孔道上安装对应的立柱、横联、斜撑和节点板。本技术将塔架基础及平衡索锚固结构进行融合设计，在满足塔架基础要求的同时，兼顾平衡索锚固功能。
