The HRW method is designed to address issues associated with existing shallow excavations, such as bracing interference, earth anchor encroachment on adjacent properties, high costs, and extended construction time.
This technology improves economic efficiency and constructability by utilizing helices, which can be retrieved after installation, and simplifies the construction process compared to anchor shoring
Depending on the ground conditions, it is easy to adjust the number and size of the helices to secure various pullout resistance levels.
Compared to existing technologies, the effective diameter and pullout resistance have improved, resulting in an area shared by each helix increasing by over 120%.
The HRW method omits processes such as grouting, pressurization, cementing, and tensioning compared to anchor methods, leading to better economic efficiency.
