Springleaf & Tagore

As of today, 6 crawler cranes and 1 piling rig lies at the Springleaf site. A hydromill trench cutter has been attached to one of the cranes, marking the start of excavation for the diaphragm walls.

Trench excavation process
2 cutting drums are attached to the base of the trench cutter, operating in reverse circulation as it excavates the earth. As it excavates, soil is loosened, broken down and mixed with a support fluid which is then pumped to the desanding plant at the surface via mud pumps. The slurry is then cleaned and subsequently recirculated into the trench.
