AI Technical Summary

⚠Technical Problem

During the installation of the wind turbine foundation ring, the deformation of the foundation ring caused by high-temperature welding makes it difficult to meet the levelness requirement within 2mm, affecting the installation accuracy of the wind turbine unit.

⚗Method used

The welding process involves first welding the steel beams to the bottom of the foundation ring, and then gradually welding upwards. This is combined with real-time monitoring using a laser level to ensure consistent welding parameters. Stiffening steel plates and steel pipe piles are used for support to minimize deformation of the foundation ring during the welding process.

🎯Benefits of technology

The levelness variation of the foundation ring was effectively controlled, ensuring the installation accuracy of the wind turbine, reducing the workload of re-welding and adjustment, improving construction efficiency and reducing costs.

Abstract

The application provides a construction technology for connecting steel beams in foundation ring construction, comprising the following steps: embedding and assembling a support body for supporting the foundation ring in advance on the outer periphery of the foundation ring; connecting a steel beam between the foundation ring and the support body, and welding the steel beam with the foundation ring and the support body respectively to realize the installation of the foundation ring; welding in the order of first welding the steel beam with the foundation ring, then welding the support body outside the steel beam and the foundation ring after the welding is completed and cooled; welding the steel beam with the foundation ring in the direction from bottom to top along the height direction; the steel beam is several, and the several steel beams are symmetrically constructed with the foundation ring as the center of symmetry, and the two symmetric steel beams are simultaneously constructed in the symmetric construction. The application fully considers the melting reaction caused by high-temperature welding, maximally reduces the height change of the foundation ring, and makes the foundation ring meet the levelness requirement of 2mm.
