Description

Single mast forepoling drill rig designed to perform consolidation operations for the creation of medium- and large-sized tunnels through the execution, before excavation, of the front and external perimetric forepoling or jet-grouting injections. It is therefore possible to operate in sections of tunnel with a diameter greater than 14 metres and with a treatment depth of up to 24 metres in conditions of maximum reliability, even in the case of extremely onerous uses, with very high production rates, thanks to the adoption of numerous innovative technical solutions and to careful dimensioning of all the structural parts. The mast is equipped with a very efficient system for support and collection of the hydraulic piping and drilling fluid transportation system which goes to the rotary in order to prevent free piping which could interfere with the rest of the machine or make transfer and drilling operations difficult.
