Reliable vertical support and secure foundation construction! It is an eco-friendly method.
The "FB9 method" is a construction technique that mechanically expands and excavates the supporting ground at the tip of steel pipe piles, creating an enlarged foundation bulb using a cement milk jet mixing method. This method has been recognized as having equal or greater bearing capacity than the intermediate excavation piles specified in the road bridge guidelines. The soil and sand discharged during the intermediate excavation can be treated as construction-generated soil, preventing secondary pollution. Additionally, it is a low-pollution method with low noise and vibration levels. 【Features】 ■ Environmental conservation ■ Reliable anchoring to the enlarged foundation bulb at the pile tip ■ High excavation efficiency ■ Integrity between the steel pipe pile and the tip bulb ■ Fast continuous construction *For more details, please download the PDF or feel free to contact us.
