Components of the Well Foundation :
(I)Well Curb and Cutting Edge :
a. Bottom portion of the well is tapered and is called well cur
b. It should be strong enough to transfer the design load. Cutting edge, which is integral part of the well curb, is usually made of rails or mild steel plates and angles. Edge of the cutting is sharp to facilitate cutting of soil. Inclined portion of the well curb facilitates easy sinking. After the well curb, outer dimension of the well is very slightly reduced. and this facilitates in reducing skin friction, while sinking the well.
