Reinforcement Work for
Excisting Steel Tower for
Firefighting Emergency Radio Tower at Sendai

This is a project of seismic reinforcement of existing steel towers. The objective was to increase the strength of the ground, and we were able to achieve 100% improvement of the footing directly beneath the existing structure using the jet grouting method (φ6.4m, oscillation type, 160-degree fan-shaped jet grouting column) without causing any damage to the existing structure.

In addition, we also carried out the construction of communication tower fabrication, reinforcement of existing communication towers, excavation work, embankment work, slope shaping work, and vegetation work.
