Large Diameter Wells Service

So far in the excavation of these pits were limited only to land media texture to drilling because ould not cross the rocks of extreme hardness and interventions on such grounds could be considered almost prohibitive to the usual technical knowledge so far tested.

In December 2007 the high specialization of "know how Ital Sonda " studing and put in practice a new method of excavation defined “digging vertical cutter”, making for the first time in Italy a vertical drilling shafts with a diameter of 3000 mm and with a depth of tens of meters underground in lava soil of extreme hardness and resistance geomechanical (> 1800-2500xcmq Kn)

The methodology digging vertical cutter to be pushed without limitation divided into several stages:

Phase A (Geological Study)

1. Geognostic surveys and knowledge of the land to be crossed
2. Detailed study of the geomechanical strength of soils

Phase B (Planning)

1. Detailed studies of the excavation equipment and the most appropriate
2. Study phase processing and organization of site

Phase C (Construction)

1. Weakening of the core of excavation
2. Excavation progress and push for vertical
3. Removal of land resulting
4. Erection of the pipe jacket
5. Anchorages and cementing

Thanks to this new type technology Italsonda today can satisfy any kind of technical and structural requirements for the formation of these works also finding many uses in various fields of use reducing by far is the execution time that the costs of its implementation compared to the old technology of excavation weakening of micro, superficial progress, progress in depth, erection of piping
