King Pile - Sheet Pile Wall Combinations
Combined sheet pile walls are typically formed by joining a pair of sheet pile sections with regularly spaced king pile patterns. sheet Combined sheet pile walls are mostly used in marine applications where they provide increased stiffness combined to regular sheet pile walls. In marine applications, it is common for the king piles to be driven to a greater depth so that greater axial capacity is obtained.
Combined steel sheet piling is used in many types of temporary works and permanent structures. The sections are designed to provide the maximum strength and durability. The design of the section interlocks facilitates pitching and driving and results in a continuous wall with a series of closely fitting joints. Care should be taken since special interlocks are required between the king piles and the sheet pile walls. Corrosion protection is required for permanent combined sheet pile walls.
For earth retaining systems, the most typical configurations include:
Single H-king pile - sheet pile wall combination
Double H-king pile - sheet pile wall combination
Pipe pile - sheet pile wall combination
King pile wall advantages
Increased wall stiffness
Increased wall moment resistance
Sheet piles can be terminated at higher elevations
King piles can extend deeper to better bearing strata
Might offer a better alternative to other systems
Ideal for heavy marine applications
King pile wall disadvantages
Increased cost when compared to standard sheet piles
Installation more complex compared to sheet piles
Greater coating surface when compared to sheet piles
