DIAPHRAGMS, POLES OR JET-GROUTING
When the excavation is confined by diaphragms or micropiles, the drainage system –similarly to the plant with sheet piles – proceeds by installing the equipment inside the excavation itself (or externally in some cases) for the abatement of the groundwater up to the desired level. Particular attention must be paid to the type of protection chosen to adapt the system, with the possibility of concluding the drainage with the aid of drainage pipes.
