Method for manufacturing, transferring and installing conversion section concrete tower drum
The invention belongs to the technical field of wind power engineering concrete tower drum construction, and particularly relates to a manufacturing, transferring and installing method of a conversion section concrete tower drum. A prefabricated annular steel plate is installed and leveled on a prefabrication site, an inner formwork is installed, reinforcing steel bars are bound on the outer side of the inner formwork, a steel strand hole channel is reserved, two sets of embedded sleeves are embedded in the side wall of the inner formwork in a bilateral symmetry mode, the outer formwork is closed, a conversion section tower drum is poured, and the formworks are dismantled. Connecting a connecting rod in each pre-embedded sleeve, hanging a steel wire rope on the connecting rod and hoisting the conversion section tower drum, so as to complete the manufacturing, transferring and mounting of the conversion section concrete tower drum. According to the method, pouring is conducted through an inverted method with the upper opening facing downwards and the lower opening facing upwards, the conversion section concrete tower drum is transferred to the upper opening of the middle section concrete tower drum through an overturning method, it is effectively guaranteed that after the tower drum is prefabricated, the water flatness of the upper edge opening of the tower drum meets the requirement, and the whole fan tower drum can operate safely and stably.
本发明属于风电工程混凝土塔筒施工技术领域，具体涉及一种转换段混凝土塔筒的制作及转移安装方法。本发明通过在预制场地上安装并调平预制环形钢板、安装内模板、在内模板外侧绑扎钢筋并预留钢绞线孔道、在内模板侧壁上左右对称的预埋两套预埋套筒、封闭外侧模板并浇筑转换段塔筒、拆除模板、在每个预埋套筒内连接连接杆并在连接杆上悬挂钢丝绳及起吊转换段塔筒八个步骤，完成了转换段混凝土塔筒的制作及转移安装。本发明采用上口朝下，下口朝上的“倒置法”进行浇筑，采用“翻转法”将转换段混凝土塔筒转移至中间段混凝土塔筒的上口，有效保证了塔筒预制完成后，其上沿口水平度满足要求，使得整个风机塔筒能够安全平稳运行。
