Combined pipe sheet pile wall
So-called combined tubular sheet pile walls are becoming increasingly popular for securing large slopes.
In this economical way of constructing a wall, tubular support piles alternate with steel sheet piles. Corner profiles are welded to the steel pipes for a friction-locked connection, into which the sheet piles are threaded and brought to depth during installation. Both Z-sheet piles and U-sheet piles can be used as intermediate piles for this construction method. This creates an economical wall that can take high loads.
You will find some examples in the two tables.
