Detail Description of Rotary Drilling Rig
Bored rotary drilling rig is used in bored piling. It consists of piling rig, concrete injection-molding system, power head and long spiral drilling stem. Its inclined strut adjustment, pile frame rotary and movement functions are all controlled by the hydraulic system. The cymbiform track walking-type movement mode enables flexible slew and convenient movement. The Bored rotary drilling rig can conduct long spiral drilling, which has a better pile-sinking performance than hammer piling, and has a lower damage chance than vibratory hammer.
Bored rotary drilling rig can conduct multi-pile engineering, improve the working efficiency and reduce the labor intensity. It can be equipped with various working devices to meet different needs: Drilling machine or vibratory hammer can conduct concrete pouring piling; Diesel hammer can conduct hammer driven piling; Homotaxial or multiaxial drill stem can conduct stirring pile plant engineering.
