This document discusses pile installation methods and equipment. It covers the main installation methods of driving piles and boring piles. For driven piles, it describes the key components of pile driving systems including hammers, rigs, and other accessories. For bored piles, it outlines the equipment used including drilling rigs, augers, and accessories. It also provides details on pile installation procedures for both driven and bored piles.

4. INTRODUCTION :
The commonest function of piles is to
transfer a load that cannot be adequately
supported at shallow depths to a depth
where adequate support becomes available.

6. The two main installation methods are :
1) Installation by driving
2) Installation by drilling (or boring) .

7. Principal components of the pile driving
system

8. H pile

9. Precast pile

10. Basic concepts of bored pile installation

14. 2- EQUIPMENT FOR DRIVEN PILES :
The two key players in pile driving are the pile and
hammer.
1) Rigs
2) Hammers
3)Vibratory pile drivers
4)Other driving accessories

15. 2-2 Hammers :
There are various type of pile-driving hammers that can be
used to install piles :
1) Drop hammers
2) Single- acting hammers ( steam or air )
3) Double acting hammers (steam or air )
4) Differential hammers (steam , air or hydraulic power )
5) Diesel hammer ( single or double acting )
6) Vibratory pile drivers
