Ground reinforcement work for infrastructure development | Tiger Pile | Performance certification
Tiger Pile
Acquisition of architectural technical performance certification, high-performance hybrid construction method using stepped steel pipes.
In infrastructure development, long-term stability and durability are required. In particular, the effects of ground subsidence and earthquakes pose significant challenges to the maintenance of infrastructure functionality. To address these challenges, reliable bearing capacity and high seismic resistance are essential. Our Tiger Pile Method has obtained certification for construction technology performance and provides solutions to meet these demands. 【Application Scenarios】 - Foundation reinforcement for roads, bridges, tunnels, etc. - Ground stabilization around structures such as dams and levees - Improvement of bearing capacity for critical infrastructure like airports and port facilities 【Effects of Implementation】 - Enhanced long-term stability of structures - Reduced impact on structures during earthquakes - Lower lifecycle costs for infrastructure facilities

basic information
【Features】 - This is a highly reliable construction method that has obtained the Building Technology Performance Certification (GBRC Performance Certification No. 06-12 Rev. 4). - It demonstrates high bearing capacity through a hybrid method that combines the material strength of steel pipe piles and the frictional force of column methods. - The core material effect enhances resistance to bending and shear forces during earthquakes, reducing the impact of poor ground solidification. - It has a wide applicable ground range, capable of accommodating ground conditions with N' values from 0.15 to 0.6. - Compared to general methods, it can achieve 2 to 4 times higher bearing capacity performance depending on the conditions. 【Our Strengths】 Geotec provides "total ground services," offering a one-stop solution for all ground-related tasks, including ground surveys and reinforcement design/construction for new buildings (from general construction to single-family homes), settlement correction work for existing buildings, and soil contamination investigations. With extensive experience and reliable technology, we create the future of cities from the ground up.

Applications/Examples of results
It can be applied to ground reinforcement measures for a wide range of buildings and structures. Even in highly soft ground or in humus land where poor solidification due to organic components is 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 generated residual soil by up to about one-fourth or less (design example: 27 columns, improved soil volume 37.11 m³ → 8.97 m³, solidification material 12 t → 3.5 t, residual soil volume 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.
