The wells are arranged either in a line or a rectangular form where the wellpoints are created at a distance of at least 2m from each other.
Well point dewatering procedure.
Water is released at the rate of 20 to 25 liters per second at these well points which causes the soil to be dug and the well point to sink deeper into the ground.
The following procedure is adopted in the well point.
The ground water table is influenced by means of drawing it down through the well points spears that are installed around the excavation area.
Wellpoint method of dewatering excavations 1 a series of wells of required depth are created in the vicinity of the excavated area from where the water has to be pumped out.
A typical wellpoint system consists of a series of small diameters wells known as wellpoints connected via a header pipe.
Procedure of well point system.
Well points are prepared at a distance of about 1m around the area to be excavated.
