Columnar Ground Improvement "SST Method"

The columnar ground improvement technology "SST method," which enables powerful compaction in the horizontal direction, achieves overwhelming high strength, high load-bearing capacity, and cost reduction.

The SST method is based on the principle of "eliminating voids and water between soil particles to increase density and strength." Unlike conventional in-situ mixing methods, it involves excavating soil and discharging it above ground, where solidifying agents and additional sand are mixed to "combine particles of different diameters." This improved soil is then filled into the excavation hole while being "compressed and compacted with strong force" using a newly developed auger, which binds soil particles together with needle-like crystals of the solidifying agent to construct a robust column. Since the construction is visually monitored on-site, it ensures a uniform and continuous high quality. Additionally, the method allows for powerful compaction not only in the vertical direction but also horizontally, enabling the construction of columns that exhibit high strength and bearing capacity of 2,400 kN/m² as per design standards. Furthermore, the surrounding ground is also compacted strongly, significantly enhancing the overall bearing capacity of the foundation. As a result, the number of columns can be reduced, and since very little excavated soil is generated, the use of large construction machinery, water, and electricity is minimized, greatly improving the applicability and workability on-site and reducing costs. Moreover, due to the immediate development of considerable strength from compaction, the curing period for the solidifying agent is almost unnecessary, leading to a shortened construction period.

[Information] Liquefaction countermeasures using the SST method

We introduce the causes of liquefaction, SST liquefaction countermeasures, and physical principles!

This document introduces liquefaction countermeasures using the SST method. Research and development of countermeasures for liquefaction has a relatively short history, beginning at the national level after the Niigata earthquake in 1964, which caused the collapse of buildings due to liquefaction. By converting the numerous pieces of information obtained from the liquefaction damage during the Great East Japan Earthquake on March 11 into empirical values, we believe that it is possible to select liquefaction countermeasure methods that consider "cost-effectiveness." This document was created to introduce liquefaction countermeasures using the SST method. [Contents (partial)] ■ Introduction ■ Liquefaction phenomenon ■ Causes of liquefaction ■ Problems caused by liquefaction ■ Soil layers at risk of liquefaction *For more details, please refer to the PDF document or feel free to contact us.
