Conclusions
-
1.
To accomplish complete interception of the inflow of groundwater to a perfect (fully penetrating) trench by light wellpoint vacuum installations, wellpoints with high sand filling or wellpoints with air pipes should be used in the installations.
-
2.
A comprehensive calculation of complete interception can be performed by the given method determining the order of performing the calculation operations.
