Combined wall systems are used when regular sheet piles are not strong enough to carry the required loads. The two main components of a combined wall system are the king pile (Painer PSp profile or Pipe) and a pair or tripple of intermediary sheet piles. The connector is the third component and it can be welded to or interlocked with the king pile and connects the king pile to the sheet pile. The intermediary sheet piles transfer the soil and water pressures to the king piles, which carry most of the load. The sheet piles are usually shorter, varying from 60% to 100% of the length of the king pile. The king piles are often designed to carry substantial vertical loads in addition to the normal bending loads.
- Modular system, which provides options for combined sheet piling plus optimum adaptation to suit structural and constructional requirements
- Secure, structural connections
- Interlocks not sealed by soil particles
- Good driving characteristics thanks to essentially symmetrical arrangement of pile sections.
