Abstract
The invention relates to a process and a device for the production of drilling holes from an angled position with respect to the drilling axis, wherein the system has a free-moving drilling support with a drilling machine axially movable thereon. According to this process the drilling rod is provided with a flexible configuration that is diverted by passing through a bend guide affixed to a drilling support, from the rotation axis of the drilling machine to the axis of the drill hole. According to this device, the flexible drilling rod system consists of a tubular core and of wires or rods twisted around this core.
Claims27
Device for forming drill hole from an angled position with respect to a longitudinal axis of said drill hole comprising:
- a freely movable drilling support;
- a drilling machine supported by said support drilling and movable along a rotation axis relative to said support;
- a bend guide mounted on said drilling support;
- a flexible drilling rod passing through said bend guide from the rotation axis of said drilling machine to the longitudinal axis of said drilling hole, said rod including a tubular core and a plurality of wires twisted around said core, said twist being no more than three circumrevolutions per meter of drilling rod.
