Anti-crack high-toughness high-strength high-rigidity wind power tower drum with composite structure and manufacturing method thereof
The invention relates to an anti-crack high-toughness high-strength high-rigidity wind power tower tube with a composite structure and a manufacturing method thereof, and belongs to the technical field of wind power tower tubes. Each tower drum fragment in the wind power tower drum is mainly composed of a concrete anti-rust layer, a steel plate layer and a concrete rigidity enhancing layer from outside to inside. The concrete anti-rust layer is made of high-initial-crack-strength high-tensile-strain low-shrinkage impervious ultra-high-performance concrete; the concrete rigidity enhancement layer is composed of high-rigidity high-initial-crack-strength low-shrinkage ultra-high-performance concrete and composite steel bars. The composite steel bars are composed of negative poisson ratio steel bars and common steel bars. The steel plate layer is formed by taking a steel plate as a framework, and inner and outer side anchoring structures are arranged on the steel plate. According to the method, the stress, durability and safety performance of the ultra-high-performance concrete prefabricated wind power tower are improved from multiple aspects of increasing prestress, reducing breakage of prestressed steel bars, reducing shrinkage of the ultra-high-performance concrete, increasing tensile strain and tensile strength, well connecting all the prefabricated parts and preventing the wind power tower from collapsing too fast.
本发明涉及一种抗裂高韧性高强度高刚度复合结构风电塔筒及其制造方法，属于风电塔筒技术领域。所述风电塔筒中的每个塔筒分片从外向内主要由混凝土防锈层、钢板层和混凝土刚度增强层组成；混凝土防锈层由高初裂强度高拉伸应变低收缩抗渗超高性能混凝土制成；混凝土刚度增强层由高刚度高初裂强度低收缩超高性能混凝土和复合钢筋组成；复合钢筋由负泊松比钢筋与普通钢筋组成；钢板层由钢板作为骨架构成，钢板上设有内、外侧锚固构造。本发明从增加预应力、减少预应力钢筋断裂、减少超高性能混凝土收缩，增加拉伸应变、抗拉强度、连接好各个预制构件以及防止风电塔筒过快倒塌多方面入手，提高了超高性能混凝土预制风电塔筒的受力、耐久及安全性能。
