Reinforcing system and reinforcing method of wind power generation tower foundation ring foundation
The invention relates to a reinforcing system and reinforcing method of a wind power generation tower foundation ring foundation. The system comprises the foundation ring foundation (1) and a draught fan tower drum (2). The foundation ring foundation (1) comprises a foundation bottom plate (10), a concrete column pier (9) and a foundation ring (8), and the foundation ring (8) is connected with the draught fan tower drum (2). Steel beams (5) are symmetrically arranged on the outer side of the foundation ring (8) and on the top of the concrete column pier (9), the steel beams (5) surround the foundation ring (8) to form a regular-hexagon-shaped area, and steel-reinforced concrete beams (6) are poured around the regular-hexagon-shaped steel beams (5) and on the outer side of the foundation ring (8). The two ends of the steel beams (5) are connected with prestress anchor rod assemblies (7), and the lower ends of the stress anchor rod assemblies (7) are anchored in the foundation bottom plate (10). Pre-tension force is applied to a prestress anchor rod, so that pre-compressive stress is generated on concrete around the foundation ring, and accordingly the crack problem of the foundation ring foundation caused by fatigue can be fundamentally solved.
