WELLPOINT SYSTEM

The Wellpoint systems are used when it is necessary to realize excavations in the presence of water, especially for the construction industry, allowing the temporary lowering of the water table in order to promote the dry excavation and prevent cave-in of its walls through the extraction water from underground. The Wellpoint System is so called because the filter tip is the so-called "Wellpoint".


This system is used in all those permeable soils for porosity, for example:

SANDY SOIL
Medium permeability

LOAMY AND CLAYEY SOILS
Low permeability

GRAVELLY SOILS
High Permeability

REMEMBER

Prima di procedere alla progettazione di un sistema wellpoint in campo edile è necessario acquisire almeno le seguenti informazioni:

Stratigraphy of the land concerned to a depth at least two times higher than that of the excavation, to determine the type of implant to be used, the type of installation, the depth of the filter tips, and the distance of the plant from the excavation;

The coefficient of permeability of the soil by means of in situ tests, to determine the distance of the filter tips, the number and power of the suction groups;

Interdependence of the aquifer with surrounding hydrological conditions such waterways;

Logistical conditions of the construction site, to determine the planimetric plant, the means necessary for the installation and execution times.

Il sistema Wellpoint è l'ideale se utilizzato in queste attività:

GEOTECHNICAL DRAINAGE
To increase the soil resistance and to increase their stability

AGRICULTURAL DRAINAGE
To reclaim the land and make it cultivable

DRAINAGE PROVISIONAL
To produce works of engineering that require excavations affecting the water table
