The casing may possibly increase to The entire depth or may well terminate above the bond zone, Together with the reinforcing bar continuing to the full depth.
API pipes (American petroleum Institute pipes ) are significant-grade pipes getting a diameter of 5 inches to 11 inches. These pipes are joined using high energy machined flush variety joint threads.
The rebar cage is the same as the cage Utilized in traditional piling. Threaded couplers are accustomed to be a part of the bars together with staggered joints. A centraliser (as per fig) is utilized for positioning the rebar cage Within the bore.
Both of those within and outdoors on the API pipes shall be grouted with or devoid of putting rebar. Centrally reinforcing sort of solid threaded or regular rebar variety (ref fig) can be employed as rebar. API PIPE Units are suggested for compression piles to keep up their lateral steadiness.
