Diaphragm walls are common practice in civil engineering as part of or as aids to the building of civil and hydraulic structures.
Info on Soilmec Hydromill Module SH-50:
Mounted on Crane Tiger SC-135:
Basically, a trench is excavated in the ground, generally in the presence of a stabilizing fluid, and it is then back-filled with an appropriate material. The material is cut and loosened with two cutting wheels mounted at the bottom of a steel frame and rotating in opposite directions.
Mud treatment unit SMT-500:
The loosened or cut material mixes into the bentonite slurry suspension which is pumped from the trench by a very powerful suction pump mounted on the hydromill and conveyed to a mud treatment unit plant for cleaning. Hydromill offers a greater rate of penetration for the excavation than most any other type of diaphragm wall technique and also offers the highest level of accuracy in verticality.
