SOCKETING OF BORED PILES IN ROCK
2017-5-14 · of bored piles being used are 1000 mm, 1200 mm and 1500 mm. Since these piles are designed for heavy loads (from 450T to 650T per pile), they are essentially to be taken to bed rock level and are to be socketed into rock. In the piling specifications, socketing in solid/hard rock is usually specified for termination criteria. For all practical
