Sheet steel pile joints are durable.
Steel sheet pile installed.
Design moment would be considered equivalent.
Since hot rolled steel sheet piles are produced from steel at high temperatures the interlock tends to be tighter.
They are installed in sequence along the planned excavation perimeter.
For example say in a section of plans which has 500 feet 152 m of wall length and a sheet piling length of 48 feet 14 6 m you require a minimum design moment of 75 8 k in ft 28 kn m m.

As the piling was going on we moved a total of 70 000 cy of dirt installed 30 000 square feet of sheet pile put in the storm water pipe and demoed 10 000 cy of concrete all within five weeks.
Jetting involves delivering a water jet to the soil at the toe of the sheet pile reducing friction.
There are several ways to install steel sheet piles into the ground.

In piling hot rolled steel sheet pile and cold formed steel sheet pile are two primary methods of manufacturing sheet pile.
Outer sheet piles are installed with 5m offset from the deep pit structure first on the three sides to the required elevation as required based on the ifc drawing and geotechnical investigation report and one side is left open for moving manpower equipment for earthwork excavation and for removal of excavated material to designated area to dumping yard.
Pre auguring refers to the use of a continuous flight auger to penetrate the ground along the pile line in advance of the sheet pile installation.
Individual pieces or pre interlocked pairs are installed by driving using impact hammers vibrators or by water jetting.
Then any hot rolled steel piling section meeting the required 75 8 k in ft.
While there are differences between these two methods the most important distinction is the interlock.
