Camellia nitidissima type structure main tower construction method
The invention provides a camellia nitidissima type structure main tower construction method which comprises the following steps: correspondingly dividing each tower column into a plurality of tower body sections, tower arch sections and closure sections according to a three-dimensional model, and calculating and processing a template and a framework of each section; pouring the tower body sections, and for the tower body sections which incline outwards by more than or equal to 5 degrees in the transverse bridge direction and the longitudinal bridge direction, mounting a tower body longitudinaltensioning device between every two tower bodies, and mounting tower body transverse tensioning devices in the tower bodies so as to ensure the line type control of the tower bodies; pouring the tower arch sections and the closure sections; installing a tower arch longitudinal restraining device between every two tower arches; and installing and tensioning stay cables, and dismantling the tower body longitudinal tensioning devices, the tower body transverse tensioning devices, the tower arch longitudinal restraining devices and a supporting steel frame after tensioning is completed. By meansof the method, it is guaranteed that the line type of the main tower meets the design requirement, and the stability of the main tower structure can be guaranteed in the construction process.
本发明提供了一种金花茶式结构主塔施工方法，包括以下步骤：依照立体模型，将每个塔柱均对应划分若干个塔身节段、塔拱节段和合拢段，计算并加工出各个节段的模板和骨架；浇注塔身节段，对于横桥向和纵桥向均外倾≥5°的塔身节段，还包括：在两个塔身之间安装塔身纵向张拉装置，在塔身内安装塔身横向张拉装置，以保证塔身的线型控制；浇注塔拱节段和合拢段；在两个塔拱之间安装塔拱纵向约束装置；安装斜拉索并张拉，张拉完成后拆除塔身纵向张拉装置、塔身横向张拉装置、塔拱纵向约束装置和支撑钢架。通过本发明保证主塔的线型符合设计要求，且能在施工的过程中保证主塔结构的稳定性。
