All casing method(6)
This is a method of excavating and removing soil within a tube using a hammer grab while oscillating and pushing in a casing tube to protect the borehole wall.
-
Reverse engineering method(1)
The protection of the borehole wall is achieved by the difference in water head between the water inside the borehole and the groundwater, using a standpipe installed at the surface. The excavation method involves rotating the bit at the tip to cut into the ground and discharging it to the surface using a suction pump along with the water inside the borehole.
-
Multi-drill method(1)
It is a method that is compact and highly mobile, capable of accommodating multiple types of work (all casing/earth drill/auger methods) simply by changing attachments.
-
Seismic-resistant pile driving method(1)
This is a composite cast-in-place pile that replaces parts with high bending moments and shear forces, such as the pile head, with steel pipe concrete piles to further enhance the seismic resistance of conventional cast-in-place concrete piles.
-
Expanded base pile method(1)
The protection of the borehole wall is carried out with casing in the surface layer and with stabilizing fluid at greater depths. Drilling is performed by rotating a drilling bucket to cut into the ground and discharging the soil contained in the bucket to the surface.
-
Vibrator Treme method(1)
Attach the air vibro to the tip of the tremie pipe, and fill the area around the pile with aggregates and concrete through vibration.
-
BKF method(1)
This is a revolutionary construction method that uses a hydraulic transmission system operated by the weight of the hammer grab to open and close the shell, allowing for excavation while achieving lower noise and vibration compared to conventional hammer grabs.
-
SENTAN. Pile Method(1)
This is a technology that improves the pile construction method of the all-casing method, where after excavation is completed, a concrete ring installed at the bottom of the hole is pressed into the ground with a specified load to strengthen the tip soil, allowing for verification of the improvement status.

H-type PC pile(1)
The "H-shaped PC pile" is a prestressed concrete member with an H-shaped cross-section manufactured in a factory, and it is a construction method that builds retaining walls by continuous driving using a three-point pile driver. During construction, it is used as a temporary retaining wall, and at the time of completion, it is used as the final structure. The cross-sectional dimensions are available in three types: width 1070(mm) × height 540, 640, 740(mm), and the design standard strength of the concrete is 70(N/mm²).
