Soilmec SR-80 CAP Hydraulic Rotary Rig Double rotary for cased augered piles

The versatile SR-80 drilling machine used both with telescopic bars and Continuous Flight Auger (CFA) is here on display in its double rotary version for Cased Augered Piles (CAP). This technology maintains the typical speed of auger drilling while adding the privilege of the casing protecting and driving the hole, which makes the machine particularly suited to perform cased secant piles (CSP). Ultimately this technology is proposed in some cases as a winning alternative to the traditional bored pile. The lower rotary featuring a large passageway allowing the separate extraction of the auger whenever required, leaving the casing in place. Finally, in order to ensure jobsite safety, the SR-80 is equipped with a spoil collecting and conveying system. This system is characterized by its simplicity and the fact that it does not hinder the drilling stroke, which can still reach the maximum depth afforded by the machine.
