AI Technical Summary

Technical Problem

In existing technologies, the prefabrication of steel shell segments in steel-concrete towers leads to extended construction periods and limited room for improvement in construction quality.

Method used

The construction method adopts precast concrete-steel shell composite segments, including the positioning and support of inner and outer wall panel units, welding, concrete pouring, welding robot welding, and construction of bridge site ring concrete. The rigidity of the segments is improved by replacing dense angle steel with concrete, and the construction cycle is shortened.

Benefits of technology

By replacing dense angle steel with concrete, the overall rigidity of the segments was improved, the construction period of the bridge site was shortened, and the construction quality and precision were guaranteed.
