Hybrid construction method for obtaining architectural technology performance certification that contributes to equipment stability.
In factory construction, a strong and stable foundation is required for the stable operation of large equipment and precision machinery. In particular, vibrations during operation and the placement of heavy objects can impose significant loads on the foundation, potentially causing settlement and differential settlement. These issues can have serious consequences, such as reduced equipment accuracy, malfunctions, and production line stoppages. The Tiger Pile Method by Geotech Co., Ltd. is a soil-cement column method that uses a stepped steel pipe as the core material and has obtained certification for construction technology performance. By combining the material strength of steel pipe pile methods with the large frictional force of column methods, this hybrid method overcomes the challenges of ground variability and small-diameter steel pipe piles, ensuring reliable high load-bearing capacity. The core material effect also enhances resistance during earthquakes, reducing the impact of some poorly solidified areas. 【Application Scenarios】 - Ground improvement for large machinery installation sites - Prevention of settlement in precision equipment installation areas - Ground reinforcement due to production line expansions - Ground strengthening in areas requiring vibration mitigation 【Benefits of Implementation】 - Stable operation and longevity of equipment - Maintenance and improvement of production accuracy - Reduction of risks from unexpected ground settlement - Assurance of a safe operating environment

Applications/Examples of results
It can be applied to ground reinforcement measures for a wide range of buildings and structures. Even in humus soil where very soft ground and poor solidification due to organic components are likely to occur, making conventional soil column design difficult, it enables reliable design and planning by considering the material strength of the core material (60-400 kN). When compared to general methods under the same ground conditions, the high load-bearing capacity significantly shortens the improvement length, reducing the amount of improved soil, solidification materials (cement-based solidifying agents), and the amount of generated residual soil to about one-fourth or less (design example: 27 columns, improved soil amount 37.11 m³ → 8.97 m³, solidification material 12 t → 3.5 t, residual soil amount 7.4 m³ → 1.8 m³). It achieves shortened construction periods and reductions in CO2 and exhaust gases from construction equipment, demonstrating excellent economic and environmental performance.
