Tower column construction method in pulling-supporting combined temporary consolidation of variable-cross-section special-shaped cable tower
The invention relates to a variable cross-section special-shaped cable tower pulling-supporting combined temporary consolidation tower column construction method, which comprises the following steps of: arranging a tower side hoop at the upper part of a pre-cast tower section, and arranging a tower side supporting frame and a first counter weight at the inclined template side; a second balance weight is arranged on the side, facing the cast-in-place tower section, of the supporting platform of the bottom support; the positions of the stiff framework and the cable bent tower reinforcement cage are controlled by comprehensively adopting the framework position control bolts, the framework tie bars and the bar top positioning bodies; a formwork position adjusting plate and a formwork position correcting bolt are arranged on the side of the inclined formwork, and the position of the inclined formwork is controlled by comprehensively adopting the formwork position correcting bolt and a telescopic supporting rod; a third counter weight and a formwork inner supporting rib are arranged on the inclined formwork side, and the third counter weight is combined with the tension of a tension rope; and when the first pouring pipe and the second pouring pipe are sequentially adopted for concrete pouring construction of the post-pouring tower section, the height of the partition inserting plate is controlled through the lifting bolt. The positioning precision of the post-pouring section formwork is improved, and the stability of the supporting structure is enhanced.
本发明涉及一种变截面异形索塔拉‑撑组合临时固结中塔柱施工方法，方法如下：在先浇塔段的上部设置塔侧抱箍，并在俯斜模板侧设置塔侧撑架及第一配重；在底部支架的支撑平台面向现浇塔段侧设置第二配重；综合采用骨架控位栓、骨架拉筋和筋顶定位体控制劲性骨架及索塔钢筋笼的位置；在仰斜模板侧设置模板调位板及模板校位栓，综合采用模板校位栓和伸缩撑杆控制仰斜模板的位置；在俯斜模板侧设置了第三配重和模板内撑筋，采用第三配重与张拉绳索的拉力组合；依次采用第一浇筑管和第二浇筑管进行后浇塔段混凝浇筑施工时，并通过升降螺栓控制分区插板的高度。本发明提高了后浇段模板的定位精度，增强了支撑结构的稳定性。
