A Well Point is a piece of pipe that has openings large enough to allow water to enter but also small enough to keep the water-bearing formation in place. There are a variety of well point designs but we are going to look at PVC well points and PVC well Screens.
3 Ιουλ 2024 · Well Point is a well of small diameter that is used for dewatering. Parts consisting in a Well Point are a shallow shaft, a dewatering pump to draw water, a riser pipe that connects the Well Point to the surface, and a small well that fills up. The diameter of a riser pipe is around 38 to 50 mm.
14 Αυγ 2021 · A wellpoint is essentially a pipe that has an opening diameter such that it avoids movement of the water bearing formations but at the same time allows water to enter. Typical wellpoint opening is around 38-50mm in diameter.
2 Οκτ 2024 · A Well Point is a piece of pipe that has openings large enough to allow water to enter but also small enough to keep the water-bearing formation in place. The well point is then drove into the ground, passing the soil and clay until it has reached water bearing gravel and sand.
Typically, Well points are used by people who own country property or cottages near lakes as they use them to install their main or secondary water supply system. There are three basic types of wells, bored/drilled, dug and driven. Well points are used for driven well types.
A wellpoint is a small diameter water abstraction point (the well screen), sometimes referred to as a ‘strainer,’ (So called because of the wire mesh or other strainers of the self-jetting wellpoint) through which the groundwater passes to enter the wellpoint.
