Replacing and replacing construction method of elevated bridge stand column
The invention belongs to the technical field of viaduct construction, and discloses a replacement construction method for viaduct stand columns, which comprises the following steps: along the height direction of an original stand column, chiseling off part of original concrete at two ends of the top surface of the original stand column to a first preset depth, and exposing first steel bars in the two chiseled-off positions of the original stand column; the original stand columns incline towards the first direction, and the direction opposite to the first direction is the second direction. The partial length of the top of the first steel bar at the chiseling position is cut off, and the remaining first steel bar after cutting is inclined by a preset angle in the second direction; overlapping a second reinforcing steel bar at the top of the inclined first reinforcing steel bar, wherein the second reinforcing steel bar extends in the vertical direction and can correspond to the position of a sleeve in the bent cap; and the repair concrete is poured into the two chiseled-away positions again, so that the inclined first steel bars are wrapped by the repair concrete, and a new stand column is formed after the repair concrete is solidified. The construction efficiency can be improved, and the cost is reduced.
本发明属于高架桥梁施工技术领域，公开了一种高架桥梁立柱的拆换施工方法，包括：沿原有立柱的高度方向，在原有立柱的顶面的两个端头处凿除部分原有混凝土至第一预设深度，使原有立柱在两个凿除位置处的内部的第一钢筋外露；其中，原有立柱向第一方向倾斜，第一方向的反方向为第二方向；截断凿除位置处的第一钢筋顶部的部分长度，并将截断后剩余的第一钢筋均朝向第二方向倾斜预设角度；在倾斜后的第一钢筋顶部搭接第二钢筋，第二钢筋沿竖直方向延伸并使第二钢筋能够与盖梁内的套筒位置相对应；向两个凿除位置重新浇筑修复混凝土，使修复混凝土将倾斜后的第一钢筋包裹在内，等待修复混凝土凝固形成新立柱。本发明能够提高施工效率，降低成本。
