Embodiment Construction

[0020] A reinforcement method for a foundation ring bottom flange, comprising the following steps:

[0021] A new opening 7 is opened on the outer side of the base ring bottom flange 1;

[0022] U-shaped radial steel bars 3 that open outwards are arranged through the newly added openings 7;

[0023] Circumferential reinforcing bars 4 are respectively arranged in the upper and lower parallel sections passing through the U-shaped radial reinforcing bars 3 .

[0024] Such as figure 1 , figure 2 As shown, it is a steel bar assembly made by adopting the reinforcement method of the foundation ring bottom flange of the present invention. Directional reinforcing bars 3, circumferential reinforcing bars 4 respectively arranged in the upper and lower parallel sections of the U-shaped radial reinforcing bars 3.

[0025] There are 3 original openings on the outer side of the base ring bottom flange 1, and 117 new openings 7, all 120 openings are evenly distributed in a ring shape, an...

Abstract

The invention discloses a foundation ring bottom flange reinforcement method and a steel bar assembly in the technical field of wind power generation foundation structure design, and aims to solve theproblem that in the prior art, the outer side concrete of the foundation ring bottom flange is easy to crack due to overlarge tensile stress, under the influence of the long-term load of the fan, thefoundation can be shook or even collapsed, and great potential safety hazards is caused. The method comprises the following steps that a newly-added hole is formed in the outer side of the foundationring bottom flange, a U-shaped radial steel bar with the outward opening is arranged through the newly-added opening hole; annular steel bars are arranged on the upper parallel section and the lowerparallel section of the U-shaped radial steel bar respectively.

Description

technical field [0001] The invention relates to a reinforcement method for foundation ring bottom flanges and a reinforcement component, and belongs to the technical field of wind power generation foundation structure design. Background technique [0002] The connection form between the wind turbine and the fan foundation generally includes two types of foundation ring and anchor bolts. The connection form of the foundation ring fixes the foundation ring to the fan foundation made of concrete through the flange. In the prior art, the concrete on the outer side of the ring bottom flange of the foundation is prone to cracking due to excessive tensile stress. Under the influence of the long-term load of the wind turbine, the foundation of the wind turbine may shake or even collapse, posing a great safety hazard. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned defects or one of the defects existing in the prior art, an...
