Diaphragm Wall
Diaphgram wall is roughly divided into (1) a method of excavating a wall-like groove hole under the ground while preventing collapse of the excavation wall surface using a stabilized solution, inserting a reinforcing cage into the groove hole, and then placing concrete or the like into the groove hole to construct a continuous wall, and (2) a method of kneading the original position soil and cement milk into columns using three-axis stirring wings and the like, inserting H-shaped steel into the column, and constructing a soil cement wall.

Cement milk is mixed and reused to create mountain fastening walls.
It is an ECO method that reduces the amount of excavated residual soil, and can be used in large depths.(Actual result: 70 m)
RC continuous wall
It is possible to construct a reinforced concrete wall that can be used in the ground with high rigidity.
The excavator equipped with a correcting device can be used for construction even at a depth of 100 m class.
SMW
In-situ mixing and stirring of cement milk and soil makes it possible to use the steel as a water stop wall. In addition, a continuous mountain-fastening wall can be constructed by inserting H-shaped steel. Three-axis augers are mounted on a three-point pile driver, which is a base machine. The screws at both ends are completely wrapped and drilled and kneaded, thereby creating a highly water-resistant mountain wall.
