When completing piles in the diameter range 600 to 1500 mm, the use of a a rotary drilling rig is often inefficient. Crane work is required to install the reinforcement, tremie pipes as well as during the subsequent concreting process, for which the drilling rig is only equipped with an auxiliary winch. <\/p>\n\n\n\n
To ensure safe retraction of the casings, very large drilling rigs are used uneconomically, deliberately avoiding the use of a casing machine. For larger construction projects, it is therefore more economical to use a drilling rig exclusively for the production of the cased borehole and a crane with a compact LEFFER casing pulling machine for the completion of the pile. <\/p>\n\n\n\n
