COMBINED WALL SYSTEMS

Combined wall systems are used when regular sheet piles are not strong enough to carry the required loads. There are a wide variety solutions which give the designer a great deal of flexibility. Each type of system, beam and pipe, has their own advantages.

Components of a combined wall system are:

• Primary: King pile and a pair of intermediary sheet piles

• Connector welded to or interlocked with the king pile connecting 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 piles. The king piles are often designed to carry substantial vertical loads in addition to the normal bending loads.

Applications of Combined Wall Systems • Large Capacity Retaining Walls with Deep Excavations

• Breakwaters

• Deep Cofferdams

• Structures Requiring Retaining Walls to Resist Large Loads
