Reinforcing device and reinforcing method for wind turbine foundation concrete pillar
The invention discloses a reinforcing device for a wind turbine foundation concrete pillar, and belongs to the field of wind turbine foundation reinforcement. The reinforcing device comprises a splittype steel ring arranged on the periphery of the concrete pillar, the split type steel ring comprises at least two arc-shaped sections, every two adjacent arc-shaped sections are fastened and connected through a corresponding flange and a corresponding bolt, the steel ring fastened and connected together applies confining pressure to the outer side of the pillar to reinforce the pillar, the innerradius of the steel ring is slightly smaller than the outer radius of the pillar, and the height of the steel ring is equal to the pillar height. The invention further discloses a reinforcing method of the wind turbine foundation concrete pillar. According to the device and the method, through confining pressure loading of the split type steel ring on the concrete pillar, the circumferential tensile stress in the concrete pillar is effectively reduced, generation and expansion of pillar cracks are effectively inhibited, the bonding performance of steel bars and concrete can further be enhanced, the problem that the concrete pillar is prone to cracking and grout emitting is thoroughly solved, and a reliable guarantee is provided for normal operation of a wind turbine. The reinforcing methoddoes not need to damage an existing wind turbine foundation structure, construction is efficient, and manpower and time cost are saved.
本发明公开了一种风机基础混凝土台柱的加固装置，属于风机基础加固领域。该加固装置包括设置在混凝土台柱外周的分体式钢环，分体式钢环包括至少两个弧形段，两两相邻的弧形段之间通过法兰和螺栓紧固连接，紧固连接在一起的钢环对台柱外侧施加围压形成加固。钢环内半径略小于台柱外半径，其高度等于台柱高度。还公开了风机基础混凝土台柱的加固方法。本发明通过分体式钢环对混凝土台柱的围压加载，有效降低混凝土台柱内的环向拉应力，有效抑制台柱裂缝的产生及扩展，还能增强钢筋与混凝土的粘结性能，彻底解决混凝土台柱容易裂缝、冒浆的问题，为风机正常运行提供可靠保障。该加固方法无需破坏现有风机基础结构，施工高效，节省人力及时间成本。
