The installation method (jetting, insertion into boreholes, etc.) for the well-points is highly dependent on the subsoil conditions. The pictures show well-points in the form of self-jetting well-point. The self-jetting well-points are installed using high-pressure water supplied to the top of the riser pipe from a water jetting pump. At the tip of the self-jetting well-point below the wellpoint screen, there is a hollow jetting shoe. Near the lower … |
