Adapted for depths of over 50m underground! A thrust construction method that penetrates the ground without excavating the surface.
We would like to introduce our "Shield Method" for constructing tunnels underground. Using a tunnel boring machine called a "shield," we advance underground while preventing soil collapse, safely conducting excavation and lining work inside to build the tunnel. This method adapts to a wide range of soil types and minimizes subsidence. It is also suitable for depths of over 50 meters underground. 【Features】 ■ Adaptability to a wide range of soil types ■ Minimization of subsidence ■ Simultaneous backfill injection is possible ■ Suitable for deep depths and high water pressure *For more details, please refer to the PDF materials or feel free to contact us.
