Direct Mud Circulation method of pile foundation installation is used for bored cast-in-situ piles. Direct Mud Circulation method is best suited when working-space is a huge constraint. In Industries and power plants where there is a labyrinth of pipelines snaking all around, DMC comes to the rescue. While the other methods are comparatively expensive, DMC is a fairly cheaper method to install piles. The apparatus basically comprises a Tripod with pulley, winch machine, wire-rope, Chisel, drill pipes, tremie pipes, a vertical pump, and a pit where bentonite powder is mixed with fresh water. A tripod as the name suggests is a three-legged structure that is mounted with a pulley at the apex to maneuver the chisel that bores the earth, which is further appended to drill pipes in tandem with a wire rope that is ultimately knotted to the winch machine. To make it sound simple, the chisel is the primary boring tool and the drill pipes are mere appendages that provide the depth, and also, suffuse the bore with bentonite suspension. The number of drill pipes required varies depending on the depth of the bore required. Besides this, a vertical pump is installed in the bentonite pit so as to pump the bentonite solution into the borehole through drill pipes and a chisel. The method is termed as Direct Mud Circulation because it involves the circulation of mud from the pile bore directly to the bentonite pit where the pump reuses the bentonite slurry leaving alone the settled mud.
