Abstract (en)
Concreting device for rotary heads of continuous flight augers (C.F.A.). It consists of a "kelly" bar (1) annexed to the rotary head (2) of a piling rig. Inside the bar a double-effect hydraulic cylinder (3) is placed. The concreting tube (6) is attached to the cylinder's piston (5), therefore the tube being able to switch between two positions: the retracted one (boring phase) and the extended one (concreting phase). During the latter, the lowermost part of the tube (6) is placed below the nose of the boring auger. By means of this device, the concreting tube (6) does not take away any length from the boring rig mast. The invention allows to join in a single rig the advantages of traditional and STARSOL piling systems. <IMAGE>
