Dismantling method and dismantling auxiliary device for mixed tower
The invention provides a dismantling method and an auxiliary dismantling device for a mixed tower, and relates to the technical field of wind power generation. The dismantling method comprises the following steps: S1) dividing the mixed tower into a first treatment section and a plurality of dismantling sections; s2) dismantling a prestressed steel strand of the mixed tower; (S3) accessories in the first treatment section are dismantled, and secondary prestress steel strands are applied to the multiple dismantled sections; s4) performing trepanning and chiseling operation at the joint of the first treatment section and the adjacent removal section; s5) hoisting the first treatment section to a specified position; s6) defining the topmost dismantling section as a to-be-dismantled section, and dismantling accessories in the to-be-dismantled section and the secondary prestressed steel strand between the to-be-dismantled section and the adjacent dismantling section; the dismantling method and the dismantling auxiliary device solve the problem that in the prior art, a mixed tower is difficult to dismantle after reaching the designed age limit, the mixed tower is difficult to dismantle.
本发明提供的混塔的拆除方法及拆除辅助装置，涉及风力发电技术领域。拆除方法包括：S1）将混塔划分成第一处理段和多个拆除段；S2）拆除混塔的预应力钢绞线；S3）拆除第一处理段内的附件，向多个拆除段施做二次预应力钢绞线；S4）在第一处理段与相邻拆除段的连接处执行开孔剔凿作业；S5）将第一处理段吊运至指定位置；S6）定义最顶部的拆除段为待拆段，拆除待拆段内的附件以及待拆段与相邻拆除段之间的二次预应力钢绞线；S7）在待拆段与相邻拆除段的连接处执行开孔剔凿作业；S8）将待拆段吊运至指定位置；重复执行步骤S6）‑S8），完成混塔拆除。该拆除方法和拆除辅助装置，解决了现有技术中混塔达到设计年限后拆除困难的问题。
