This construction method is capable of responding to the earthquake resistance, deterioration, and increasing size of vessels at low cost with a short construction period while the facilities are in service.
This method improves the soft ground from the sea by using a special ship.
This method uses a rotary penetration device and a specially shaped head at the tip of the casing to construct compaction piles on soft ground with no vibration and low noise.
This large-diameter (φ 1600 mm to 2000 mm) deep mixing treating method mixes and stirs slurry solidification material and in-situ soil by relative mixing of the outer and inner blades.
This method uses a special stirrer attached to the tip of a backhoe type machine to mix slurry-like improver with in-situ soil to form a stable improver.
The CDM (Cement Deep Mixing) method mixes and stirs slurry solidification material and in-situ soil. The amount of soil equivalent to the input amount of solidification material is then discharged and the construction is carried out without affecting the surrounding ground or structures.
