Dramatic improvement in the reliability of piles! A construction method developed with consideration for the surrounding environment, seeking low noise and low vibration.

The "SENTAN Pile Method" is a construction method based on the all-casing method. After excavation is completed, a split concrete ring installed at the bottom of the hole is pushed in with a load of 2,000 kN/m² or more for each ring, thereby strengthening the tip ground and allowing for pile installation. It is suitable for structures with uneven settlement or strict settlement restrictions, and is appropriate for foundations of railway viaduct construction divided into first and second phases, as well as for the widening of road bridge piers. 【Features】 ■ Dramatic improvement in pile reliability ■ Reduction in total costs ■ Applicable to various structures ■ Compliance with design standards *For more details, please refer to the PDF materials or feel free to contact us.

basic information

【Other Features】 - By applying historical loads, effects similar to those obtained from load tests for verifying bearing capacity can be achieved. - For all piles, the penetration load and settlement amount can be managed in real-time on a computer at ground level. - Since the end bearing capacity of the piles is improved, it is possible to reduce the pile diameter, pile length, and number of piles. - Suitable for structures with uneven settlement or strict settlement restrictions. - In the "Road Bridge Design Guidelines" and "Design Standards for Railway Structures," as well as the design guidelines of the former Japan Highway Public Corporation, the improvement effects on bearing capacity and deformation performance are clearly stated for end-reinforced cast-in-place piles. *For more details, please refer to the PDF materials or feel free to contact us.
