A soil retaining system combining flat sheet pile walls in an open cell configuration includes integral soil anchors providing an improved earth retaining system. Another aspect of the invention is a method of designing and installing a soil retaining system with an open sheet pile cell structure having integral soil anchors. The method includes, inter alia, calculating soil forces by taking into account material strength of sheet pile, soil friction against the sheet pile in combination with the strength of the integral soil anchor, selecting sheet pile size and length based on soil forces calculation; and installation of sheet pile to form a soil retaining system. The integral soil anchors serve to provide higher load resistance to the improved earth retaining system.

A pin pile is disclosed for anchoring sections of sheet pile to form a wall structure. The pin pile has a casing with a plurality of external clutches formed around the periphery. In use other corresponding clutches on the sections of sheet pile can interlock with the external clutches of the pin pile over a range of angles in accordance with a directional extent of said wall structure.

A continuity connection system is disclosed that is highly durable, simple to install, and substantially increases the structural capabilities and weight-bearing capacity of a shell (i.e., a form or jacket). The shell can be used to protect a weight-bearing member (e.g., a cement column) from a degrading environment. The shell can have one or several layers of carbon fiber fabric (e.g., spaced apart longitudinally) wrapped around an interior of the shell or embedded within the shell. The continuity connection system is used to provide continuity between two ends of the carbon fiber layer, and can be made up of the carbon fiber fabric reinforcement layer, two pockets, and a laminate having ends positioned in each pocket. The carbon fiber laminate traverses a seam/separation of the carbon fiber fabric and/or a seam of the shell and can be retained in place within the pockets with an appropriate epoxy, for example.
