Method and structure for transforming existing foundation ring type fan foundation
The invention relates to a method and structure for transforming an existing foundation ring type fan foundation, and belongs to the technical field of identification and reinforcement. The method comprises the following steps that original reinforced concrete in an existing foundation ring is hollowed out, and holes are drilled in the bottom of the interior of the existing foundation ring to plant steel bars; a plurality of anchor bolt rods are embedded in the hollowed existing foundation ring in the circumferential direction, and the height of an anchor bolt rods is larger than that of the foundation ring; new reinforced concrete is re-poured into the excavated existing foundation ring, the strength of the poured new reinforced concrete is larger than that of the original reinforced concrete. According to the method for transforming the existing foundation ring type fan foundation, the structure of an original fan foundation and an excellent machine position of an original wind field can be utilized, the problem of environmental damage caused by machine position replacement can be reduced, and the method for transforming the existing foundation ring type fan foundation also has obvious economic benefits.
本发明涉及一种既有基础环式风机基础改造方法及结构，属于鉴定加固技术领域，该方法包括如下过程：挖空既有基础环内部原有钢筋混凝土，在既有基础环内部底部钻孔植筋；在挖空后的既有基础环内部圆周方向埋置若干根锚栓杆，其中所述锚栓杆高度要大于基础环的高度；向挖空后的既有基础环内部重新浇筑新的钢筋混凝土，浇筑新的钢筋混凝土的强度要大于原有钢筋混凝土的强度，该方法可以利用原有风机基础的结构，可以利用原风场优良机位，不仅可以减少更换机位带来的环境破坏问题，还具有显著的经济效益。
