Chimney perpendicularity control and deviation rectification construction method
The invention discloses a chimney perpendicularity control and deviation rectification construction method. The method comprises the following steps that S1, the center point of a chimney cylinder body foundation is determined; s2, determining and checking the central position of the chimney cylinder body; s3, centering inspection and positioning are conducted on the chimney cylinder body reinforcing steel bars and the outer formwork; and S4, deviation correction is conducted, specifically, the center deviation direction is determined according to the measurement result of the bottom of the chimney cylinder body, the number of times of lifting is increased for 5-10 hydraulic jacks in the center deviation direction, meanwhile, needle valves of other hydraulic jacks are closed, and one side of the operation platform is raised intentionally to correct the center. The operation platform is visual, clear and simple, and it is proved that the whole operation platform is parallel to the ground and does not deviate all around as long as it is observed that the relative positions of reference objects of the center of the plumb bob and the center of the bottom of the chimney coincide at any time in the lifting process and after the plumb bob is jacked in place.
本发明公开了一种烟囱垂直度控制及纠偏施工方法，包括以下步骤：S1：烟囱筒身基础中心点的确定；S2：烟囱筒身筒体中心位置的确定及检验；S3：烟囱筒身钢筋和外模板对中检验及定位；S4：纠偏：根据烟囱筒身底部测量结果定出中心偏差方向，对中心偏差方向的5～10个液压千斤顶增加提升次数，同时关闭其他液压千斤顶的针型阀，使操作平台一侧有意提高来纠正中心。直观，清晰，简洁，只要在提升过程和顶升到位后，随时观测这个铅锤中心和烟囱底部中心参照物的相对位置重合，那就证明整个操作平台是平行与地面的，没有发生前后左右的偏移。
