This involves choosing the appropriate pile diameter, size, and product to deliver sufficient load-carrying potential and resistance to settlement and lateral masses.
The condition of such casings shall be absolutely free from considerable distortion and shall have a uniform cross area all over the duration.
extend pile Concreting at the least 60cm to 90cm higher than the cutoff stage to make sure excellent concrete for proper embedment into pile cap.

The exam load information ended up gathered and converted into graphical forms. The effects have been interpreted via load-settlement curves making use of many approaches for figuring out the allowable load bearing ability with the pile.
