Composite material anti-crack high-strength prefabricated combined wind power tower drum and manufacturing method thereof
The invention relates to a composite material anti-crack high-strength prefabricated combined wind power tower drum and a manufacturing method thereof, and belongs to the technical field of wind power tower drums. Each tower drum slice in the tower drum is mainly composed of an outer side concrete slice layer, a steel plate layer and an inner side concrete slice layer from outside to inside. The outer side concrete sheet layer is mainly composed of high-initial-crack-strength low-shrinkage ultra-high-performance concrete and outer side composite steel bars. The inner side concrete sheet layer is mainly composed of high-tensile-strain low-shrinkage ultra-high-performance concrete and inner side composite steel bars. The invention aims to provide a comprehensive crack control technical scheme for the ultra-high performance concrete prefabricated wind power tower drum. The method starts from multiple aspects of increasing prestress, reducing fracture of prestressed steel bars, reducing shrinkage of the ultra-high performance concrete, increasing initial crack strength of the ultra-high performance concrete on the outer side, increasing tensile strain of the ultra-high performance concrete on the inner side, well connecting all prefabricated parts and preventing the tower drum from collapsing too fast. Therefore, the stress performance, the durability and the safety performance of the ultra-high performance concrete prefabricated wind power tower drum are improved.
本发明涉及一种复合材质抗裂高强预制组合风电塔筒及其制造方法，属于风电塔筒技术领域。所述塔筒中的塔筒分片从外向内主要由外侧混凝土片层、钢板层和内侧混凝土片层组成；外侧混凝土片层主要由高初裂强度低收缩超高性能混凝土与外侧复合钢筋组成；内侧混凝土片层主要由高拉伸应变低收缩超高性能混凝土与内侧复合钢筋组成。旨在为超高性能混凝土预制风电塔筒提供较为全面的裂缝管控技术方案，从增加预应力、减少预应力钢筋断裂、减少超高性能混凝土收缩、增加外侧超高性能混凝土初裂强度、增加内侧超高性能混凝土拉伸应变、连接好各个预制构件以及防止塔筒过快倒塌多方面入手，从而提高超高性能混凝土预制风电塔筒的受力、耐久及安全性能。
