Foundation transformation structure with large fan replacing small fan
The invention relates to a foundation transformation structure with a large fan replacing a small fan. The foundation transformation structure comprises an original concrete foundation, a new concrete foundation, prestressed anchor bolt assemblies, prestressed chemical anchor rods, prestressed anchoring units and original vertical ribs. The new concrete foundation is arranged on the original concrete foundation; the prestressed chemical anchor rods and the original vertical ribs are arranged in the original concrete foundation and the new concrete foundation in a penetrating manner; the prestressed anchoring unit penetrates through the original concrete foundation and the new concrete foundation and is connected with a soil body; the pre-stressed anchor bolt assembly is arranged in the new concrete foundation, and the foundation transformation structure is connected with the upper fan tower drum through the pre-stressed anchor bolt assembly. Compared with the prior art, the thickness of the foundation is increased without increasing the diameter of the foundation, the excavation volume of the on-site foundation can be greatly reduced, and the operation difficulty is reduced; the bearing capacity is large, and the anti-fatigue bearing capacity of the stand area is improved; the prestress anchoring unit is adopted for transforming the foundation, the bearing capacity of the transformed foundation is greatly improved, and a foundation ring of an original foundation is taken out.
本发明涉及一种大风机代替小风机的基础改造结构，包括：原混凝土基础、新混凝土基础、预应力锚栓组合件、预应力化学锚杆、预应力锚固单元、原竖筋；新混凝土基础设于原混凝土基础上；预应力化学锚杆、原竖筋均穿设于原混凝土基础、新混凝土基础内；预应力锚固单元贯穿原混凝土基础、新混凝土基础，并与土体连接；预应力锚栓组合件设于新混凝土基础内，基础改造结构通过预应力锚栓组合件与上部风机塔筒连接。与现有技术相比，本发明增加基础厚度而不增加基础直径，可大幅度减小现场基础的开挖量，降低操作难度；承载力大，提高台柱区域的抗疲劳承载力；采用预应力锚固单元改造基础，极大提高改造基础承载力，将原来基础的基础环取出。
