The drilling of water wells is performed with a drill that supports and rotates a drilling shaft with a notched chisel able to drill rocks or any boulders find in the underground.
For the first one or two meters, where the ground is inconsistent, a pipe with a diameter greater than that of the final well is first fixed, then it is drilled until reaching the groundwater. Once the flap is reached, the pipe that constitutes the real well is inserted and can be made of non-toxic steel in areas with layers of incoherent material (ie sand and fine gravel), or, in classic PVC in case of rocky materials.
The first meters of the tube (the deepest ones) are equipped with a window in the area near the pitch to allow water to enter the pipe. The well must then be completed by placing some siliceous gravel in correspondence with the windowed area and cementing the part towards the surface to prevent superficial drainage from entering the well and therefore into the water table with the consequent possibility of pollution.
The well must then be drained and kept pumped for a few hours or even a few days to clean it from silt and sand that pass through the well-windowed area of the well tube. Subsequently the submerged electro-pump is inserted with its delivery pipe (RC drilling Australia). Then the well is sealed with a special steel cap that can be at ground level or inside a concrete
A micropile is a special foundation pole used for the reclamation of buildings and buildings characterized by structural subsidence. These types of events may be due to several factors, for example, landslides.
The installation of micropiles, which are usually small in size compared to medium-sized poles but, on the other hand, are more easily applicable even in urban settings. it is necessary where the presence of other buildings or protrusions like balconies can make the work of a team specialized in the consolidation of buildings and land more difficult.
Thanks to the action of the micropiles, it is possible to report in depth those loads that a particular structure entrusts to the subsoil, in the specific case in which the characteristics to support them are not present in the ground at the base of the building.
When in a field it is necessary to identify in detail the stratigraphic sequence, it is necessary to perform a continuous drilling rig. The carrots extracted during the survey are placed in special cataloging boxes (in wood, metal or plastic), equipped with dividers and a hinged lid.
The boxes must be kept, for as long as necessary, protected from atmospheric agents. The RC drilling Australia technique currently most used for continuous drill drilling is the rotary drilling technique. The ground is pierced by a tool pushed and rotated by a coil of rods.
