Combination sheet pile walls are typically formed by joining a pair of sheet pile sections with regularly spaced king pile patterns and are typically 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 (HZM or tube) together with intermediate sheet piles. The H pile uses standard clutch connections to enable effective transfer of loading from the adjacent sheet piles. The sheet piles are normally shorter than the H piles, varying from 60% to 100% of the length. The H piles are often designed to carry substantial vertical loads in addition to the normal bending loads.
Combination Walls are generally used for large retained heights or where ground conditions are too weak to offer sufficient resistance to the pile loads, requiring long piles to reach more competent soils. In marine applications, it is common for the king piles to be driven to a greater depth so that a bigger axial capacity is obtained.
