Columnar Ground Improvement "SST Method"

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

[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.

Why not update the water pipes without stopping the road?

Why not update the water pipes without stopping the road?

Minimizing both traffic congestion and noise. A next-generation water pipe renewal method that connects to the future.

When it becomes necessary to update water pipes on a busy road, concerns about traffic congestion, noise, and vibrations due to construction arise. The SDF method involves inserting a new **flexible stainless steel pipe** into the aging water pipes without extensive excavation work. This significantly shortens the construction period and minimizes the impact on nearby residents and passing vehicles. It is a construction method that protects essential water infrastructure without disrupting daily life, making it friendly to both the environment and people.

Ground improvement work in Aomori Prefecture! Super Rappu Elniido method.

Ground improvement work in Aomori Prefecture! Super Rappu Elniido method.

[NETIS Registration] Construction of sediment control dams approved!

We carried out ground improvement for a sediment control dam in public civil engineering using the Super Rappu Elniido method. Excavation and improvement were performed down to the bedrock of the supporting layer, and sloped cross-section shaping was also conducted. In mountainous sites, construction conditions are limited, such as the selection of construction machinery and materials. However, the Super Rappu Elniido method can be implemented with basically a general-purpose backhoe and a small amount of materials, making it possible to work in narrow areas. We also introduce various case studies on pages from other prefectures.

[Column] Comparison of Other Construction Methods and Processes / The Reason for the Significantly Faster Construction Time

[Column] Comparison of Other Construction Methods and Processes / The Reason for the Significantly Faster Construction Time

Comparison of construction methods and processes / The reason why the construction time is overwhelmingly fast.

Can we achieve an overwhelming reduction in construction time? ⬛︎Explanation 1: No "slurry production" (compared to cement milk/pile improvement) In the cement milk method and pile improvement, the process begins with "slurry production," where cement and water are mixed at a batch plant. In fact, this preparation alone takes about 90 minutes for a site using 30 tons of cement. The Super Rappu Elneed method eliminates this entire preparation process. Since the solidifying agent is directly inserted in its package, there is no need for a plant or slurry production. The insertion work that took 90 minutes is completed in just 5 minutes. ⬛︎Explanation 2: No "formwork assembly and dismantling" (compared to the Rappu method) In the Rappu method, after "excavation," "formwork assembly" is performed, and after the concrete hardens, "formwork dismantling" occurs. These tasks require specialized craftsmen and are time-consuming processes. The Super Rappu Elneed method utilizes the sides of the excavation hole as a substitute for formwork (earthen formwork), eliminating the entire series of tasks related to "formwork." This allows for reductions in work time, labor costs, and material costs.

[Joint Development with the Ministry of Land, Infrastructure, Transport and Tourism] Ground improvement with a site strength ratio of 1.0 or higher! Support layers visible.

[Joint Development with the Ministry of Land, Infrastructure, Transport and Tourism] Ground improvement with a site strength ratio of 1.0 or higher! Support layers visible.

Eliminating the "invisible" concerns of column improvement. Achieving both direct visual inspection of the support layer and a field strength ratio of 1.0 or higher. Comprehensive comparison table with conventional methods and design standard strengths.

This is a technical document aimed at preventing quality issues in ground improvement. It allows for direct visual confirmation of the "support layer," which has been difficult to verify with conventional columnar improvement methods. Furthermore, through strict slurry management, it achieves a strength ratio of "strength ratio ≥ 1.0," which is generally said to be around 0.2 to 0.8 (field test specimen strength / laboratory mix strength). Please take a look at this reliable quality management method developed in collaboration with the Ministry of Land, Infrastructure, Transport and Tourism and registered with NETIS. 【Contents】 Overview of the method and its reliability Challenges of conventional methods and the technical superiority of this method Design advantages and application conditions Features of quality management
