Why piling is required?
End bearing piles: These piles are used to bear vertical loads. They are driven into the ground until hard bed is met with. The load of super structure is transferred to the hard strata through these piles. These piles act similarly like columns carrying structural load but below ground level. Friction piles: There are various types of friction piles however, most common and widely used in building construction is under-reamed pile. Under reamed piles: (Instruments used for work) * Auger with special blades to excavate the pile hole * Reaming tool to form the bulb. * Bucket to collect and remove the excavated soil from the hub. * Extension rod to extend the length of reaming tool or auger. * Tripod or pulley block to take out the reaming tool or auger from hole. Dewatering work : In some cases while excavating, it happens that one meets with water at intermediate stage, before reaching the required strata. Unless and until the water is removed, one can not proceed with the work. In mos
