Composite iron tower bearing platform suitable for frost heaving area and construction method
The invention discloses a composite iron tower bearing platform suitable for a frost heaving area and a construction method. The iron tower bearing platform has the gradient functions of high durability and high toughness and comprises a tower foot steel structure embedded part, a UHPC prefabricated base, a UHPC prefabricated shell and core area functional gradient concrete, and the tower foot steel structure embedded part is of a hollow bell-shaped appearance; and shape parameters are optimized by utilizing a topology technology, so that the strength requirement of stress transmission is met under the condition of minimum material consumption, and the self weight of the structure is reduced. The UHPC component is prefabricated and maintained in a factory, the quality of the component is guaranteed, and meanwhile the factory level of a project is improved; on the construction site, rapid assembly construction is achieved through annular notches formed in the UHPC prefabricated base, the construction speed is increased, and meanwhile the construction difficulty is greatly reduced; and the UHPC shell is also used as a template for pouring the field functional gradient concrete inner core, so that manufacturing and erecting of the template in the construction process are avoided.
本发明公开一种适用于冻胀区的复合铁塔承台及施工方法，所述的铁塔承台具有高耐久性和高韧性梯度功能包括塔脚钢结构埋件、UHPC预制底座、UHPC预制外壳和核心区功能梯度混凝土四部分，所述塔脚钢结构埋件采用空心钟状外形，利用拓扑技术优化形状参数，实现最小材料用量下，满足应力传递的强度需求，降低结构自重。在工厂进行UHPC构件的预制与养护，保证构件质量的同时提升工程的工厂化水平。在施工现场，利用UHPC预制底座设置的环状槽口实现快速拼装施工，加快施工速度的同时大幅降低施工难度。现场功能梯度混凝土内芯的浇筑也以UHPC外壳作为模板，避免了施工过程中模板的制作与架设。
