2. my country has become the world's largest carbon dioxide emitter since 2007, and the increasing energy demand is in contradiction with the rigorous task of energy saving and emission reduction. my country has abundant onshore wind energy resources, and the development of wind power energy has become an important part of the national energy structure transformation strategy. In order to obtain stable power generation, wind turbines are erected high in the sky through supporting structures. In recent years, the single-unit capacity, hub height and diameter of wind power structures have been gradually increasing. Due to the limited bearing capacity of traditional conical steel tower support structures, it has become increasingly difficult to meet the trend of large-scale development of wind power structures. First of all, the increase in the wall thickness of the round steel pipe has a limited contribution to the lateral stiffness of the member, and the increase in the diameter is restricted by the processing cost and transportation conditions. Secondly, the local buckling of the round steel pipe section will cause the section's bending resistance to decline rapidly, and it will become more serious as the diameter-to-thickness ratio increases.

3. The cost of concrete per cubic meter is less than one-tenth of steel per ton. The introduction of concrete will reduce the amount of steel used in supporting structures and help break through the application limitations of wind power structures due to cost and other issues. In order to reduce the transportation size and lifting weight, the concrete tower usually needs to be prefabricated in pieces in the factory and assembled on site. However, the resulting horizontal and vertical joints not only destroy the integrity of the structure, but also affect the construction Quality and construction schedule. For example, the use of grouting material to smooth the wet connection of the filling joint, because the construction quality inside the sealing strip is often unable to be visually inspected, and the construction will be interrupted due to the difficulty of improving the strength during winter construction. The utility model integrally casts the longitudinal steel bars of the tower section and the connecting flange to form a frame, and then stretches the ring prestressed tendons to form a whole, which not only improves the ductility and stability of the tower tube, but also improves the installation efficiency of each tower section , Realizing the effective compatibility of "high integrity" and "quick construction". It avoids the need for excessive installation accuracy and the adverse effects of winter construction.
